Our resolution of this error reduced the median amount of time sites spent on the malware list. ![]() We rectified the error within a day and removed the erroneously classified sites from the malware list. We flagged the hosting providers for malware instead of the infected subdomains by mistake because it is difficult to determine which domains were maintained by each hosting provider. Safe Browsing scanners identified malware on subdomains of a significant number of hosting providers. Safe Browsing’s algorithms automatically identify these domains and detect more than 6,000 attack sites per week. Attack sites had been using a technique called “domain rotation” to quickly move their malware distribution networks. Safe Browsing identifies malware campaigns that infected more than 62,000 sites, redirecting users to the attack site gumblar.cn/. In total, Safe Browsing identifies more than 100,000 infected hosts during this week.Īpril 2009. The previous campaign that originally launched attacks from gumblar.cn/ starts directing users to martuz.cn/, which infects more than 42,000 sites. Users receive more than 90 million browser warnings and 330 million search warnings per week as a result. A large majority of these sites redirected users to the Blackhole exploit kit. More than 90,000 sites compromised with malware are identified. However, these feeds must meet stringent standards to ensure very low false positive rates. Phishing protection in Safe Browsing obtains some of its data from third-party feeds. One of the third-party phishing feeds that provides Safe Browsing with data is temporarily removed because of concerns with too many false positives. The same Blackhole campaign that caused more than 90 million browser users to receive malware warnings also generated more than 330 million warnings in Google Search. However, users continue to see a warning page if they click on a link to an unsafe site, and the number of warning page views during this time increases by 31%. ![]() An error prevents malware warning labels from appearing on Google Web Search results (Image Search is unaffected) and decreases the number of labels displayed directly on the results page. Malware warnings on Google SearchĪpril 28, 2013. Safe Browsing's Client Side Phishing detection algorithm launches in Google Chrome, which doubles the number of phishing warnings that users receive each week. More than 90 million users receive malware warnings as a result. A large campaign infects more than 106,000 unique sites in July, directing people to sites launching the Blackhole Exploit Kit. Cybercriminals using Red Kit infect enough sites to increase the number of users who receive malware warnings by 32 million. (Update: an earlier version of this report erroneously indicated that 75 million users received malware warnings).Īpril 2013. As a result, more than 28.6 million Safe Browsing API users receive malware warnings during this week. A campaign targeting vulnerabilities in Java and Acrobat Reader infects more than 7,500 sites. ![]() Number of sites deemed dangerous by Safe Browsing We are working to restore the data feed.įebruary 2021: Data charts for Unsafe websites detected per week and How we identify malware stopped being updated and were archived. The "Warnings displayed per week" and "Website owner response time (in days)" charts are currently only showing data through December 2022.
