Google is sharing some interesting statistics on malware, such as the number of entries on the Google Safe Browsing Malware List that have occurred over the last twelve months, and search results containing a URL labeled as harmful.
“We’re glad to share this sort of data because we believe that collaboration and information sharing are crucial in driving anti-malware efforts forward,” says Niels Provos of Google’s Security Team.
Number of Entries on the Google Safe Browsing Malware List
“As we mentioned in our Top-10 Malware Sites blog post, we have seen a large increase in the number of compromised sites since April,” says Provos. “The number of entries on our malware list has more than doubled in one year, and we have seen periods in which 40,000 web sites were compromised per week. However, compared to infections associated with Gumblar and Martuz — two relatively large and well-known pieces of malicious code, many compromised web sites now point to hundreds of different domains.”
In January of last year, 1.2% of all Google search queries contained at least one such result. The trend has mostly been downward in the time that has passed since then, although you can see fluctuations.
Search Results Containing a URL Labeled as Harmful
Google says that as malware trends evolve, they’re constantly improving their systems to better detect compromised sites. The company notes that the increase in compromised sites they observed could partially be influenced by such improvements.
