Some of the most visited sites on the Internet began delivering malware laden ads this weekend. The sites affected included The New York Times, the BBC, MSN, and AOL. Those who visited a site delivering the ads are not at risk unless they clicked on an infected ad. After clicking, users are taken to another website which attempts to infect them with either Cryptowall ransomware or a trojan that gives the attackers control of the infected computer. The good news for FOSS Force readers is that the malware seems to only work against Windows, so GNU/Linux users are considered safe.
