The week may have been cut short for some due to Thanksgiving, but the security news machine kept churning nonetheless.
A report by security firm BitDefender highlighted the challenge of malicious links and malware on Facebook. According to BitDefender, more than 20 percent of the people using the company’s safego application were exposed to malicious content in wall posts and news feeds.
“The threats we are talking about are menaces that the user gets exposed to, like a link that you should not click or a third-party app that you should not install,” Catalin Cosoi, head of BitDefender’s online threats lab, told eWEEK. “Only a small percentage of those threats were actually linking to malware. Most of the time, these are apps that will promise the user extra features, or different games, in order to convince you to install them. Once you do, they will post messages on your behalf [in order to continue spreading] and will have access to your personal information.”
According to a new report from Dasient, 1.2 million Websites were infected with malware in the third quarter of 2010. Much of that malware is being spread via drive-by downloads, the firm reported, explaining that the popularity of Web-based e-mail services such as Microsoft Hotmail and Google Gmail has resulted in e-mail attachments being scanned by antivirus technology.
Elsewhere in the world of malware, code for one of thezero-days exploited by the infamous Stuxnet worm was made public online during the week. The code targets a Windows Task Scheduler vulnerability that can be used for privilege escalation. The exploit code was added to the Exploit Database operated by Offensive Security Nov. 20. The flaw is currently unpatched, but Microsoft said a fix is forthcoming.
Google started the week off with news that it had issued a fix for a flaw affecting Gmail users. The bug was actually patched Nov. 20 after it was reported by TechCrunch. The situation impacted users who visited the site while they were still logged onto Gmail, and it reportedly worked regardless of whether or not the user was browsing in Google Chrome’s “Incognito” mode.
“We quickly fixed the issue in the Google Apps Script API that could have allowed for e-mails to be sent to Gmail users without their permission if they visited a specially designed Website while signed into their account,” a Google spokesperson said. “We immediately removed the site that demonstrated this issue, and disabled the functionality soon after. We encourage responsible disclosure of potential application security issues to [email protected].”
