Native Client

Security Contest Terms and Conditions

NO PURCHASE NECESSARY TO ENTER OR WIN. VOID WHERE PROHIBITED. CONTEST IS OPEN TO RESIDENTS OF THE 50 UNITED STATES, THE DISTRICT OF COLUMBIA AND WORLDWIDE, EXCEPT FOR ITALY, BRAZIL, QUEBEC, CUBA, IRAN, SYRIA, NORTH KOREA, SUDAN AND MYANMAR.

ENTRY IN THIS CONTEST CONSTITUTES YOUR ACCEPTANCE OF THESE TERMS AND CONDITIONS.

  1. Binding Agreement

    In order to enter the Native Client Security Contest (“Contest”), you must agree to these Terms and Conditions (“Terms”). Therefore, please read these Terms prior to entry to ensure you understand and agree. You agree that submission of an entry in the Contest constitutes your agreement to these Terms. After reading the Terms and in order to participate, each Participant (as defined below) must complete the registration form, clicking the “I understand and agree” box (or the equivalent), on the Contest entry webpage. Once the Participant clicks the “I understand and agree” box (or the equivalent), the Terms form a binding legal agreement between each Participant and Google with respect to the Contest.

    Participants may not submit an Exploit, Issue or Summary to the Contest and are not eligible to receive the prizes described in these Terms unless they agree to these Terms. If a Participant is part of a team, each member of the team must read and agree to these Terms and click on the “I understand and agree” box (or the equivalent) described herein. Failure of any member of a team to agree to these Terms and click on the “I understand and agree” box (or the equivalent) described herein will disqualify the entire team.

    By entering, Participant warrants that Participant has not violated any employment agreement or other restriction imposed by his or her employer by participating in this Contest.

  2. Description

    The Contest is organized by Google and is designed to motivate the developer community to identify and report security Exploits (as defined below) on Google’s Native Client software and reward those developers who identify one or more security Exploits that are evaluated as a winning exploit by the Judges.

    Once a Participant has registered for the Contest, the Participant will be asked to identify security Exploits in Google’s Native Client Software and enter those Exploits on Google’s Native Client Issue Tracker web site using the “Security Contest Template.” At this point, the Exploit will become an Issue and will no longer be able to be identified by another Participant. Google will then verify that the Issue is reproducible. If so, that Issue will become a Verified Issue. Finally, the Participant will submit a Summary of up to his or her top ten best Issues that were submitted on the Native Client Issue Tracker. Since it is possible that an Issue may not be verified until after the Contest End Date, if a Participant includes such an Issue in their Summary and such Issue is not ultimately verified, then that Issue will not be considered to be part of the Summary.

    Prizes will be awarded to those Participants who submit the best Summaries as determined in the sole discretion of the Judges when considering the Judging Criteria described herein.

  3. Sponsor

    The Contest is sponsored by Google Inc. (“Google” or “Sponsor”), a Delaware corporation with its principal place of business at 1600 Amphitheater Parkway, Mountain View, CA, 94043, USA.

  4. Term

    The Contest begins at 9:00:00 A.M. Pacific Time (PT) Zone in the United States on Februrary 25th, 2009 (“Contest Start Date”) and ends at 11:59:59 P.M. PT on May 5th, 2009 (“Contest End Date”). Participants must register by May 5th, 2009 at 11:59:59 Pacific Time to be eligible to participate. ENTRANTS ARE RESPONSIBLE FOR DETERMINING THE CORRESPONDING TIME ZONE IN THEIR RESPECTIVE JURISDICTIONS.

  5. Definitions

    Throughout these Terms, Google will use the following defined terms and words. Please review them carefully to ensure you understand.

    1. Covert Channel Attack: A “Covert Channel Attack” means an attempt to manipulate certain properties of a communications medium in an unexpected, unconventional, or unforeseen way in order to transmit information through the medium without detection by anyone other than the entities operating the covert channel. Exploits that are Covert Channel Attacks are excluded from the Contest.
    2. Exploit: An “Exploit” means a sequence of steps that require and use Native Client to produce or have the potential to produce behavior prohibited by Native Client’s security policies and design which can be found at http://src.chromium.org/viewvc/native_client/trunk/src/native_client/README.html. Google reserves the right to modify the security policies and design at any time. An example of an Exploit would be producing file system or network access outside of the scope of permissible use via JavaScript in a browser. An Exploit that defeats one but not all Native Client security measures is still considered to produce behavior prohibited by Native Client’s security policies for the purposes of this Contest and would be entitled to be identified as an Exploit in the Contest.
    3. Inner Sandbox: The “Inner Sandbox” means the Native Client security system that a) inspects executables before running them to try to detect the potential for an executable to produce prohibited behavior, and b) prevents from running any executables that are detected to have the potential to produce prohibited behavior.
    4. Issue: An “Issue” means an entry of a single Exploit by a Participant into the Native Client Issue Tracker using a properly filled out Security Contest Template. Once the Exploit has been properly entered it becomes an Issue.
    5. Native Client Issue Tracker: The “Native Client Issue Tracker” is located at http://code.google.com/p/nativeclient/issues/list. It is a web application that manages and maintains a list of Issues, including Issues that are not eligible for contest entry.
    6. Native Client Version Number: The “Native Client Version Number” is defined as the number between the platform name (separated by an ‘_’) and the file extension (separated by a ‘.’) in the Native Client download. For example, if the the filename of the download on the Native Client download page is “nacl_linux_0.1_32_2009_01_16.tgz” or “nacl_windows_0.1_32_2009_01_16.zip”, the Version Number is “0.1_32_2009_01_16”.
    7. Outer Sandbox: The “Outer Sandbox” means the Native Client security system that 1) observes executables while they are running to detect the attempts at prohibited behavior and 2) terminates misbehaving executables if it observes any attempts to produce prohibited behavior.
    8. Participant: A “Participant” means any individual or team of individuals that has agreed to these Terms, meets the eligibility criteria described below, and is participating in the Contest.
    9. Side Channel Attack: A “Side Channel Attack” means any attack based on information gained as a side-effect of the implementation of a cryptosystem, rather than brute force or theoretical weaknesses in the algorithms. For example, attacks that use timing information, power consumption variation, electromagnetic leaks or sound to obtain information illicitly are side channel attacks. Exploits that are Side Channel Attacks are excluded from the Contest.
    10. Summary: A “Summary” means the final electronic document complying with the requirements of Section X that each Participant must submit in order to participate in the Contest. A Summary may contain up to 10 Issues. If Issues do not ultimately become Verified Issues, they will not be considered as part of the Summary and Participant understands and accepts the risk that if the Participant identified an Issue on a Summary that had not yet been verified, that Issue will not be considered as part of the Summary if not subsequently verified.
    11. Verified Issue: A “Verified Issue” means an Exploit that has been a) submitted to the Native Client Issue Tracker in accordance with these Terms, and b) confirmed by the Native Client team at Google to exhibit the behavior described in the Issue report.
  6. Eligibility

    The Contest is open to Participants who (1) have agreed to these Terms; (2) who are of or above the legal age of majority, at the time of entry, to form valid contracts in their respective country, province or state of legal residence (and at least the age of 20 in Taiwan); (3) are not residents of Italy, Brazil, Quebec, Cuba, Iran, Syria, North Korea, Sudan, or Myanmar; and (4) who have software development experience. Sponsor reserves the right to verify eligibility and to adjudicate on any dispute at any time. The Contest is void in, and not open to residents of, Italy, Brazil, Quebec, Cuba, Iran, Syria, North Korea, Sudan, Myanmar, or to individuals and entities restricted by U.S. export controls and sanctions, and is void in any other nation, state, or province where prohibited or restricted by U.S. or local law.

    Employees and contractors of Google, affiliates and subsidiaries of Google, the Judges and members of their immediate families (defined as parents, children, siblings and spouse, regardless of where they reside and/or those living in the same household of each) are not eligible to participate in the Contest. Judges may not help any Participant with their submissions and Judges must recuse themselves in cases where they have a conflict of interest that becomes known to the Judge.

  7. Registration & Entry Process

    1. All Participants must register at code.google.com/contests/nativeclient-security/ by May 5th, 2009 at 11:59:59 Pacific Time. All individuals participating in the Contest (either as an individual Participant or as a member of a team) must provide the following registration information:

      1. Email Address(es) of the Participant. The first member of a team to register must list the email addresses of all members of the Participant team, and all members must ultimately agree to the Terms as described more fully below.
      2. Nationality and primary place of residence of the Participant.
      3. If the Participant is a team, the email address of the team member who is selected to be the recipient of the prize. The first member of the team to register will designate this information in the initial team registration.
      4. Participant name, which is the team name in the case of a team or the user name chosen by an individual in the case of an individual Participant.

      Failure to fully, completely and accurately provide this information will disqualify the Entry.

    2. Any potential prize recipient may be required to show proof of being the authorized account holder for an email address. The “Authorized Account Holder” is the natural person assigned to an email address by the relevant provider of email services.

    3. Participants that are teams must provide the above registration information for every individual who is a member of the team. Every individual who is part of the team must agree to the Terms in order for the team to be eligible to participate by clicking the “I understand and agree” box (or the equivalent) on the Contest entry webpage. Members of a team will be able to edit the information relating to the team only until the last member of the team has accepted these Terms by clicking the “I understand and agree” box (or the equivalent) on the Contest entry webpage. Issues submitted by members of a team prior to the time that all individual members of the team have clicked the “I understand and agree” box (or the equivalent) will not be valid Issue submissions and will not be eligible entries in the Contest. Google will send an email to all members of the team when the final team member has accepted the terms, however Google will have no liability for failure to send such an email or for the failure of any team member to receive the email.

    4. Issues submitted by Participants who are individuals prior to the time that the individual has clicked the “I understand and agree” box (or the equivalent) will not be valid Issue submissions and will not be eligible entries in the Contest. Google will send an email to the individual when the individual has accepted the terms, however Google will have no liability for failure to send such an email or for the failure of any team member to receive the email.

    5. All entries become the property of Sponsor and will not be acknowledged or returned. Entries are void if they are in whole or part illegible, incomplete, damaged, altered, counterfeit, obtained through fraud, or late.

    6. LIMIT ONE ENTRY PER PERSON. Individuals may only enter one time, whether as an individual Participant or as a team Participant. Google, in its sole discretion, may disqualify any Participant (including team Participants) that it believes has violated this provision.

  8. Submission Process

    1. Each Participant must submit:
      1. At least one Issue in the Native Client Issue Tracker that describes an Exploit and includes the information detailed in the “Issues” section below. Any team member can submit an Issue on behalf of the team. All entries will be deemed made by the Authorized Account Holder of the email address submitted at the time of entry.
      2. One Summary per Participant that includes the information detailed in the “Summary” section below. Participant will be entitled to amend its Summary until the Contest End Date and only the last version will be considered by the Judges.
    2. Each Issue must be written in the English language. Google or the Judges may refuse to review submissions that they deem incomprehensible, include Issues that are not repeatable as determined by Google, or that otherwise do not meet the requirements of these Terms.
    3. To enter an Issue in the Native Client Issue Tracker, each Participant must use the “Security Contest Template” and provide completely and accurately all information requested by the template. Any Issues that are not entered with the “Security Contest Template” may not be considered by the Judges. Each Issue must contain the items described in the “Issues” section of these Terms.
  9. Issues

    1. Minimum requirements for Issues: Participant must identify an Exploit and enter the Exploit into the Native Client Issue Tracker. Once the Exploit is submitted it becomes an Issue. Each submitted Issue must include (i) the following information and (ii) all additional information requested on the “Security Contest Template”:
      1. The user name (in the case of Individual Participants) or the team name (in the case of team Participants) of the Participant submitting the Issue, which must be identical to the user name or team name submitted during the registration process.
      2. A gzipped tar archive (with paths relative to nacl/googleclient/native_client/tests/) that contains any instructions and files necessary to reproduce the Exploit, which must include:
        1. A README.txt file that describes:
          • The version number of current version of Native Client at the time of submission. Issues submitted with a version number listed other than the current version at the time of submission will be invalid;
          • The steps required to reproduce the Exploit;
          • The effect of the Exploit; and
          • Platform requirements for the Exploit, including but not necessarily limited to:
          • browser version;
          • operating system name(s) and version(s); and/or
          • any other platform requirements relevant to the Exploit.
        2. If the Exploit requires a binary executable, both the source code and binary executable must be provided upon creation of the Issue. Any subsequent updates to the source code or binary executable after the creation of the Issue will not be considered for the purposes of this Contest. The binary executable must build cleanly by executing the command “make” in the exploit directory (e.g. nacl/googleclient/native_client/tests/exploit1).
    2. Verified Issues: In order for an Issue to become a Verified Issue, Google will first examine the submitted Issue to determine whether it complies with the following:
      1. The Exploit must not contain or depend upon access or use of any third party software or code that Google does not have readily available to it or that would require complying with third party license agreement that Google in its sole discretion deems onerous or burdensome.
      2. Google must be able to replicate the Exploit in its sole discretion.
      3. The Exploit must affect at least one “opt-” platform from a standard build of the most recent released version of Native Client as of the time of submission of the Issue for the Exploit.
    3. Timeliness
      1. If the vulnerability exposed by the submitted Exploit was disclosed in a previously reported Issue (whether or not submitted by a Participant) or in the previously published Native Client release notes, the submission will be invalid for the purposes of this Contest. Two Exploits are considered to expose the same vulnerability if the theoretical patch required to fix one vulnerability also fixes the second vulnerability.
      2. Google will update the Native Client source code base at most twice per week. These updates, if they occur, will appear Mondays and Thursdays between 3 p.m. and 8 p.m. Pacific Time.
      3. Issues will not be valid if they have been entered before the later of (i) the Contest Start Date or (ii) the time at which all members of a team Participant or the individual Participant, as the case may be, have accepted these Terms.
    4. Excluded Exploits. The following types of Exploits are invalid for the purposes of this Contest:
      • Covert Channel Attacks;
      • Sidechannel Attacks;
      • Exploits requiring a virtualized CPU;
      • Exploits that rely on features, misfeatures or defects of virtual machines (i.e. VMWare, Xen, Parallels etc.);
      • Exploits that require the machine to be previously compromised by malicious software (including but not limited to viruses or malware); and
      • Exploits that rely on hardware failures, other than Exploits which, in Google’s sole judgment, depend on CPU errata but which can be reproduced reliably with a common system configuration and under normal operating conditions, or statistically improbable hardware behaviors. Examples include but are not limited to Exploits that rely on memory errors induced by cosmic radiation, and Exploits that require abnormal heating, cooling or other abnormal physical conditions.
    5. Completeness. Issues submitted that lack any of the above materials or fail to meet any of the above criteria, may not be considered in the judging process at Google’s sole discretion. Issues that are not included in a Participant Summary (see section below) will not be considered.
  10. Summary

    1. Every Participant must submit a Summary at the Native Client Issue Tracker complying with the requirements of this section. The Participant must select no more than 10 of the Verified Issues submitted by the Participant for inclusion on the Summary. Each Summary must be in English and must contain the following information:
      • The Issues must be listed in descending order of severity, as determined by the Participant in accordance with the Judging Criteria.
      • Each Issue listed in the Summary must be identified by ID number of the Issue. The ID number is the identifying number created for each Issue as listed on the Native Client Issue Tracker.
      • A description of the effect of each Exploit.
      • The platform requirements of each Exploit.
      • The version number(s) of Native Client software affected by each Exploit (which must be the version number of the Native Client software current at the time the Issue was submitted to the Native Client Issue Tracker).
      • Any other details about the Exploit and the submission that are relevant to the judging criteria, such as, for example, the approach used in finding the exploits, innovative or scalable techniques used to discover exploits, or architectural analysis.
      • The team name or user name of the Participant. Google may, in its sole discretion, eliminate or disqualify any Summary that lists user names or team names that are not identical to the user name or team name of the Participant listed on the Contest entry form.
    2. Each Summary must be a maximum of 8 pages long, in PDF format viewable with Adobe Reader version 9. The Summary must be formatted for 8.5 inches x11 inches or A4 paper, with a minimum font size of 10 pt. Any submission that does not meet these formatting criteria may be disqualified at the sole discretion of Google.
    3. All Issues listed in the Summary will be verified by Google before submission of the Summary to the Judges after the Contest Closing Date. Participants may submit or resubmit their Summary at any time during the duration of the Contest, however, the Judges will consider only the last Summary from each Participant prior to the Contest Closing Date and ignore all other Summaries previously submitted by the Participant.
  11. Judging

    1. After the Contest End Date and on or about May 15th, 2009, all submitted Summaries will be judged by one of at least three panels with a minimum of three experts in the field of online security (“Judges”) on each panel. Judges will evaluate each Summary in accordance with the Judging Criteria described below. Each panel will evaluate a number of the submitted Summaries using the Judging Criteria described below and will select the highest ranking Summaries to move to the next level of judging. During the first round of judging, each panel will select no more than ten Summaries to move forward to the second round of judging unless there is a tie between or among any Participants. During the second round of judging, those Summaries selected during the first round of judging will then be evaluated by all Judges using the below Judging Criteria and the top five Summaries will be selected as potential winners. All decisions of the Judges are final and binding.

    2. Judging Criteria. The Judges will consider each Summary under following judging criteria (“Judging Criteria”):

      1. Quality of Exploit. Quality will be decided by the Judges in their sole discretion and will be based on (in order of importance to the Judges) Severity, Scope, Reliability and Style.

        1. Severity: the more disruptive the effects of the Exploit, the higher its quality. Here is a non-exhaustive ranking of the most common Exploits starting from ‘minor’ to ‘severe’:

          • Browser crash;

          • Denial of service or machine crash;

          • Compromise of the Outer Sandbox;

          • Information leak (such as of a cookie or password);

          • Compromise of both the Inner and Outer Sandbox; and/or

          • Prohibited side effect (such as reading or writing files to the client machine), escalation of privilege (such as executing other programs outside of Native Client).

          Any Exploit that does not address the above elements will be evaluated on a case-by-case basis and the severity of such Exploits will be determined solely at the Judge’s discretion.

        2. Scope: the more computers that an Exploit would potentially affect, the bigger its scope and therefore higher the quality of the Exploit. Consider the following:

          • Exploits that affect all platforms supported by Native Client (where platform is defined as a browser, operating system and hardware combination) have higher quality than an Exploit specific to a particular platform.

          • Exploits that require non-current or beta versions (historic or future) of hardware or software are lower quality.

          • Exploits that rely on concurrent usage of other installed software or web content must make a compelling case about the likelihood of the prerequisite software or content being present, or they will be considered of lower quality.

        3. Reliability: The more frequent or probable the occurrence identified by the Exploit, the more “reliable” it may be. Consider the following:

          • Exploits that require uncommon software to be installed on the machine in order to function will be deemed to have lower quality.

          • Entries that include Exploits that cannot be reproduced 100% of the time, but which can be reproduced a significant percentage of the time, will be deemed to have a lower quality to account for a lowered probability that the attack will succeed.

        4. Style: Submissions that demonstrate exceptional style will receive a higher ranking. Factors that contribute to style include:

          • Ingenuity in mechanism used to bypass security;

          • Uniqueness of the Exploit;

          • Ingenuity in methods used to discover vulnerabilities; and/or Minimal size of Exploit to achieve the effect.

      2. the Quantity of Exploits: Participants that submit more Exploits in their Summary (but no more than 10) may receive a higher ranking, weighted by quality. However, it is still possible that a Participant who submits one Exploit could still outweigh a Participant that submits several Exploits.

      Considering each of the factors described above, the Judges will give each Summary a “Score” from 1-10 that represents the Judges evaluation of the Summary. This “score” will determine which participants move from the first round of judging to the second round of judging, and which participants will be selected as a winner.

    3. Winner Selection

      Judges will review the Summaries as discussed in the “Judging” section, above. The Summaries with the five (5) highest scores will be selected as potentially winning Participants. In the event of a tie ranking for two or more Summaries, the Participant whose Summary had the highest ranking for “Severity” will receive the higher prize. In the event of a second tie, the Participant whose Summary had the highest ranking for “Scope” will receive the higher prize. Odds of winning depend on the number of eligible entries received and the skill of the Participants.

      The Judges are under no obligation to provide feedback on their decisions or on their judgment on specific Exploits they consider.

    4. Team Winners

      A special note about the prize distribution process for Participants who are entering as part of a team:

      A single member of each team shall be designated to receive the prize, if any, awarded to such team at the initial registration of the team, and Google shall have no responsibility for distribution of the prize among the team members.

      Each individual that enters as part of a team, understands and agrees that if his/her team is selected to receive a prize, the team is responsible for ensuring the funds are appropriately distributed to each member of the team. In addition, once a team has registered, the team may not add, remove, or substitute any members or otherwise change the composition of the team for the duration of the Contest. If any member of a team does not comply with these Terms, is ineligible or is disqualified, the team as a whole may be disqualified in Google’s sole discretion.

  12. Prizes

    1. Information Required for Eligibility

      1. On or about May 15th 2009 and upon selection of potential winners, Google will contact all winning Participants using the email addresses submitted at registration. In order to win the Contest and receive prizes, Participants, including each individual on a team, must provide additional information including:
        • first and last name;
        • address;
        • phone number; and
        • all other necessary information required by the US tax and legal authorities and /or the authorities of the countries they reside in.
      2. All Participants will need to verify their identity with Google, before receiving their prize; however, Participants may provide an alias for use in any public documentation and marketing material issued publicly by Google, subject to limitations of the law and as required by law enforcement. Please be aware that in some jurisdictions, a list of winners must be made available and your name, and not the alias, will be provided on that list. If a Participant, or in the case of a team, any individual member of the team, refuses or fails to provide the necessary information to Google within 14 days of the Contest administrators’ request for the required information, then Google may, in its sole discretion, disqualify the Participant’s entry and select as an alternative potential winner the Participant with the next highest overall ranking. Google will not be held responsible for any failure of potential winners to receive notification that they are potential winners. Except where prohibited by law, each potential winner may be required to sign and return a Declaration of Eligibility, Liability & Publicity Release and Release of Rights and provide any additional information that may be required by Google. If required, potential winners must return all such required documents within 14 calendar days following attempted notification or such potential winner will be deemed to have forfeited the prize and Google will select the Participant with the next highest overall ranking as the potential winner.
      3. Prizes will be awarded within 6 months after the Contest End Date.
      4. If fewer than 5 Participants or teams are found eligible, fewer than 5 winners will be selected.
      5. Prizes are not transferable or substitutable, except by Google in its sole discretion in the event a prize becomes unavailable for any reason. In such an instance, Google will award a prize of equal or greater value.
      6. LIMIT: Only one prize per Participant.
    2. Prize Amounts and Announcement

      Provided that the Participant has complied with these Terms, eligible Participants that are ranked in the top 5 positions of the competition by Judges will receive the following awards in U.S. Dollars based on their rank: 1st prize: $8,192.00, 2nd prize: $4,096.00, 3rd prize: $2,048.00, 4th prize: $1,024.00, 5th prize: $1,024.00. Winning Entries will be announced on or about December 7th.

    3. Distribution of a Prize

      Google is not responsible for any division or distribution of the prizes among or between team members. Distribution or division of the prize among individual team members is the sole responsibility of the participating team. Google will award the prize only to the one (1) member of the team, who was identified by the Participant to receive the prize as part of the registration process. Google will attempt to reach only the designated recipient for purposes of distribution of the prize.

      Prizes are awarded without warranty of any kind from Google, express or implied, without limitation, except where this would be contrary to federal, state, provincial, or local laws or regulations. All federal, state, provincial and local laws and regulations apply.

    4. Taxes

      Payments to potential prize winners are subject to the express requirement that they submit to Google all documentation requested by Google to permit it to comply with all applicable US, state, local and foreign (including provincial) tax reporting and withholding requirements. All prizes will be net of any taxes Google is required by law to withhold. All taxes imposed on the prize are the sole responsibility of the prize recipient.

      In order to receive a prize, potential prize recipients must submit the tax documentation requested by Google or otherwise required by applicable law, to Google or the relevant tax authority, all as determined by applicable law, including, where relevant, the law of the potential prize recipient’s country of residence. The potential prize recipient is responsible for ensuring that (s)he complies with all the applicable tax laws and filing requirements. If a potential prize recipient fails to provide such documentation or comply with such laws, the prize may be forfeited and Google may, in its sole discretion, select an alternative potential prize recipient.

  13. General Conditions

    1. Right to Disqualify. A Participant may be prohibited from participating in or be disqualified from this Contest if, in Google’s sole discretion, it reasonably believes that the Participant or any member of a Participant team has attempted to undermine the legitimate operation of the Contest by cheating, deception, or other unfair playing practices or annoys, abuses, threatens or harasses any other Participants, Google, or the Judges. Google further reserves the right to disqualify any Issue that it believes in its sole and unfettered discretion infringes upon or violates the rights of any third party, otherwise does not comply with these Terms, or violates U.S. or applicable local law in Participant’s country of residence.

      Google further reserves the right to disqualify any Participant who tampers with the submission process or any other part of the Contest. Any attempt by a Participant to deliberately damage any web site or undermine the legitimate operation of the Contest is a violation of criminal and civil laws and should such an attempt be made, Google reserves the right to seek damages from any such Participant to the fullest extent of the applicable law.

    2. Internet Disclaimer. Google is not responsible for any malfunction of the entire Contest, the web site displaying the Contest terms and entry information, or any late, lost, damaged, misdirected, incomplete, illegible, undeliverable, or destroyed Exploits, Issues or Summaries due to system errors, failed, incomplete or garbled computer or other telecommunication transmission malfunctions, hardware or software failures of any kind, lost or unavailable network connections, typographical or system/human errors and failures, technical malfunction(s) of any telephone network or lines, cable connections, satellite transmissions, servers or providers, or computer equipment, traffic congestion on the Internet or at the web site displaying the Contest or any combination thereof, including other telecommunication, cable, digital or satellite malfunctions which may limit an entrant’s ability to participate. Google is not responsible for availability of the Native Client Issue Tracker from your preferred point of Internet access. In the event of a technical disruption, Google may, in its sole discretion, extend the Contest End Date for a reasonable period. Google will attempt to notify Participants of any such extension by email at the email address in the registration information, but shall have no liability for any failure of such notification.

    3. Exploits Independently Discovered by Google. You acknowledge and understand that Google may discover Exploits independently that may be similar to or identical to your Issues in terms of function, vulnerability, or in other respects. You agree that you will not be entitled to any rights in, or compensation in connection with, any such similar or identical applications and/or ideas. You acknowledge that you have submitted your entry voluntarily and not in confidence or in trust.
