Rickrolling is an Internet meme typically involving the music video for the 1987 Rick Astley song "Never Gonna Give You Up". The meme is a bait and switch: a person provides a web link that he or she claims is relevant to the topic at hand, but the link actually takes the user to the Astley video.

Over the past few months we have noticed attacker efforts to maximize blackhat SEO tactics and increase infection rates at the same time by abusing the popular social news aggregate site Digg.com. Digg allows users to create, vote, and comment on news stories.

Malware distributors have been creating false stories with catchy subject lines as an attempt to bait users into clicking links which lead to Malware. In some cases the attackers do not create the news story themselves, rather linking to others relevant content. Below is an example of the attacker (in red) taking advantage of a valid digg submission. The malicious comment reads, "Heath Ledger naked in the shower, playing with herself." and is posted to a relevant story about Heath Ledger. The "playing with herself" part is a bit confusing but my guess is that the attackers are using automation scripts to auto-generate content based on topic relevancy or that they are manually doing this and have no idea who Heath Ledger is.

Example on Digg

My initial search identified 52 accounts posting news stories or comments with malicious URI's. The links all point to various fake codec sites, which lead to rogue anti-malware infections. We detect and block the malware as Adware/VideoPlay.

Update: Dancho Danchev reported that there has been over 500,000 malicious comments posted via Digg since last year.
