Odious web ads that pop up or otherwise make themselves a nuisance have been around since the internet dark ages. Occasionally, they can be more than a nuisance, especially when appearing on lesser known or unsavory websites. Adware, spyware or even malicious exploits can be served up from a web ad.
Last week exactly that happened on some well-established and highly esteemed brand names: BBC, New York Times, MSN, AOL and a few others. Cybercriminals managed to infiltrate one of the major ad delivery network and served up ads that landed readers on pages full of exploits, including the infamous Cryptowall ransomware.
Do you know how to protect yourself from ransomware? How confident are you that you could either avoid an infection, or be able to restore any encrypted files from secure backups?
