You have the option of donating these rewards to charity instead, and Google will double the amount.<br /> <br /> To qualify for the ideal integration reward, projects must show that:<br /> <br /> <ul> <li>Fuzz targets are checked into their upstream repository and integrated in the build system with <a href="https://github.com/google/sanitizers">sanitizer</a> support (up to $5,000). </li> <li>Fuzz targets are <a href="https://github.com/google/oss-fuzz/blob/master/docs/clusterfuzz.md#performance-analyzer">efficient</a> and provide good code coverage (>80%) (up to $5,000). </li> <li>Fuzz targets are part of the official upstream development and regression testing process, i.e. they are maintained, run against old known crashers and the periodically updated <a href="https://github.com/google/oss-fuzz/blob/master/docs/ideal_integration.md#seed-corpus">corpora</a> (up to $5,000). </li> <li>The last $5,000 is a “<a href="https://en.wikipedia.org/wiki/Leet">l33t</a>” bonus that we may reward at our discretion for projects that we feel have gone the extra mile or done something really awesome. </li> </ul> We’ve already started to contact the first round of projects that are eligible for the initial reward. If you are the maintainer or point of contact for one of these projects, you may also <a href="https://docs.google.com/a/google.com/forms/d/e/1FAIpQLSdh4LZVbo3TuViaHqMLbHP5J0fWe0_u_RPUupgq-HHp4W9wGg/viewform">reach out</a> to us in order to apply for our ideal integration rewards.<br /> <br /> <span style="font-size: large;"><b>The future </b></span><br /> <br /> We’d like to thank the existing contributors who integrated their projects and fixed countless bugs. We hope to see more projects integrated into OSS-Fuzz, and greater adoption of fuzzing as standard practice when developing software. <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Google Online Security Blog:OSS-Fuzz: Five months later, and rewarding projects&url=https://security.googleblog.com/2017/05/oss-fuzz-five-months-later-and.html&via=google'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://security.googleblog.com/2017/05/oss-fuzz-five-months-later-and.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='comment-container'> <i class='comment-img material-icons'>  </i> <span class='cmt_count_iframe_holder' data-count='0' data-onclick='javascript:window.open(this.href, "bloggerPopup", "toolbar=0,location=0,statusbar=1,menubar=0,scrollbars=yes,width=640,height=500"); return false;' data-post-url='https://security.googleblog.com/2017/05/oss-fuzz-five-months-later-and.html' data-url='https://security.googleblog.com/2017/05/oss-fuzz-five-months-later-and.html' style='color: #4184F3;'></span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://security.googleblog.com/2017/05/oss-fuzz-five-months-later-and.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> </div> </div> </div> <div class='post' data-id='7671315843065492633' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://security.googleblog.com/2017/05/protecting-you-against-phishing.html' itemprop='url' title='Protecting You Against Phishing'> Protecting You Against Phishing </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> May 5, 2017 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> <span class="byline-author">Posted by Mark Risher, Director, Counter Abuse Technology</span><br /> <br /> As many email users know, phishing attacks—or emails that impersonate a trusted source to trick users into sharing information—are a pervasive problem. If you use Gmail, you can rest assured that every day, millions of phishing emails are blocked from ever reaching your inbox.<br /> <br /> This week, we defended against an email <a href="https://productforums.google.com/forum/#!topic/docs/zbkCm9Ohw0s;context-place=topicsearchin/docs/phishing%7Csort:date">phishing campaign</a> that tricked some of our users into inadvertently granting access to their contact information, with the intent to spread more phishing emails. We took quick action to revoke all access granted to the attacker as well as steps to reduce and prevent harm from future variants of this type of attack.<br /> <br /> Here’s some background to help you understand how the campaign worked, how we addressed it, and how you can better protect yourself against attacks.<br /> <br /> <b>How the campaign worked and how we addressed it </b><br /> <br /> Victims of this attack received an email that appeared to be an invite to a Google Doc from one of their contacts. When users clicked the link in the attacker’s email, it directed them to the attacker’s application, which requested access to the user’s account under the false pretense of gaining access to the Google Doc. If the user authorized access to the application (through a mechanism called OAuth), it used the user's contact list to send the same message to more people.<br /> <br /> Upon detecting this issue, we immediately responded with a combination of automatic and manual actions that ended this campaign within an hour. We removed fake pages and applications, and pushed user-protection updates through Safe Browsing, Gmail, Google Cloud Platform, and other counter-abuse systems. Fewer than 0.1% of our users were affected by this attack, and we have taken steps to re-secure affected accounts.<br /> <br /> We protect our users from phishing attacks in a number of ways, including: <br /> <ul> <li>Using machine learning-based detection of spam and phishing messages, which has contributed to 99.9% accuracy in spam detection. </li> <li>Providing <a href="https://www.google.com/transparencyreport/safebrowsing/">Safe Browsing</a> warnings about dangerous links, within Gmail and across more than 2 billion browsers. </li> <li>Preventing suspicious account sign-ins through dynamic, risk-based challenges. </li> <li>Scanning email attachments for malware and other dangerous payloads. </li> </ul> <br /> In addition, we’re taking multiple steps to combat this type of attack in the future, including updating our policies and enforcement on OAuth applications, updating our anti-spam systems to help prevent campaigns like this one, and augmenting monitoring of suspicious third-party apps that request information from our users.<br /> <br /> <b>How users can protect themselves </b><br /> <br /> We’re committed to keeping your Google Account safe, and have layers of defense in place to guard against sophisticated attacks of all types, from anti-hijacking systems detecting unusual behavior, to machine learning models that block malicious content, to protection measures in Chrome and through Safe Browsing that guard against visiting suspicious sites. In addition, here are a few ways users can further protect themselves:<br /> <br /> <ul> <li>Take the <a href="https://myaccount.google.com/secureaccount?pli=1">Google Security Checkup</a>, paying particular attention to any applications or devices you no longer use, as well as any unrecognized devices. </li> <li>Pay attention to <a href="https://support.google.com/mail/answer/1074268?hl=en">warnings and alerts</a> that appear in Gmail and other products. </li> <li>Report <a href="https://support.google.com/mail/answer/8253?hl=en">suspicious emails</a> and <a href="https://safebrowsing.google.com/safebrowsing/report_phish/">other content</a> to Google. </li> </ul> <br /> <b>How G Suite admins can protect their users </b><br /> <br /> We’ve separately notified G Suite customers whose users were tricked into granting OAuth access. While no further admin or user action is required for this incident, if you are a G Suite admin, consider the following best practices to generally improve security:<br /> <br /> <ul> <li>Review and verify current <a href="https://support.google.com/a/answer/162106?hl=en">OAuth API access by third-parties</a>. </li> <li>Run <a href="https://support.google.com/a/answer/6124308?hl=en">OAuth Token audit log reports</a> to catch future inadvertent scope grants and set up automated email alerts in the Admin console using the <a href="https://support.google.com/a/answer/3230421?hl=en">custom alerts feature</a>, or script it with the <a href="https://developers.google.com/admin-sdk/reports/v1/reference/activity-ref-appendix-a/token-event-names">Reports API</a>. </li> <li>Turn on 2-step verification for your organization and use <a href="https://support.google.com/accounts/answer/6103523?co=GENIE.Platform%3DAndroid&hl=en">security keys</a>. </li> <li>Follow the <a href="https://support.google.com/a/answer/2984349?hl=en-uk&hlrm=en">security checklist</a> if you feel that an account may be compromised. </li> <li>Help prevent abuse of your brand in phishing attacks by publishing a <a href="https://support.google.com/a/answer/2466580?hl=en">DMARC</a> policy for your organization. </li> <li><a href="https://support.google.com/a/answer/6374496">Use</a> and enforce rules for <a href="https://support.google.com/a/answer/7280976?hl=en">S/MIME encryption</a>.</li> </ul>  Here is a list of more <a href="https://www.google.com/safetycenter/everyone/start/">tips and tools</a> to help you stay secure on the web.<br /> <div> <br /></div> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </script> <noscript> <span class="byline-author">Posted by Mark Risher, Director, Counter Abuse Technology</span><br /> <br /> As many email users know, phishing attacks—or emails that impersonate a trusted source to trick users into sharing information—are a pervasive problem.
