Cybercriminals have cleverly hacked the English website of the major Russian newspaper Pravda ("The Truth").
The news site has been rigged with malicious scripts that target vulnerabilities in your computer, and can silently infect your system and execute code without your knowledge, Mikko Hypponen, chief research officer for the security firm F-Secure wrote.
The hack is "particularly devious," Hypponen said, because it exploits the familiarity regular Pravda readers have developed with the website over the years.
"An end user might go to the same news website every morning for years, learning to trust it," Hypponen said. "Then one day it has become dangerous and will take over your computer, just by opening your favorite page."
To stay safe, don't visit Pravda's site, and make sure you have up-to-date antivirus software installed on your computer.
UPDATE: Pravda has now removed the malicious scripts from its website, Hypponen wrote on Twitter.
