Video-sharing site DailyMotion, one of the most popular destinations on the Web, is in the throes of an attack where it is serving malicious ads redirecting users to a fake AV scam.
Security firm Invincea reported the issue to the website, and as of 4 p.m. ET, DailyMotion was still serving the fake AV malware.
This is the second malvertising attack reported this week. Earlier, Yahoo sites in Europe were serving ads that dropped an iframe sending users to domains hosting the Magnitude exploit kit, which then seeded victims with a host of financial malware.
DailyMotion attracts 17 million monthly visitors and is the 95th-ranked website according to Alexa.
Invincea said that the malicious ads redirect to a third-party domain in Poland called webantivirusprorh[.]pl (93[.]115[.]82[.[246). According to VirusTotal, 10 of 47 antivirus products detect the threat; most detect it as a variant of the Graftor Trojan. The initial redirect, Invincea said, is loaded via engine[.]adzerk[.]net.
When the user lands on the DailyMotion home page, an invisible iframe redirects to the scam which warns the user of a critical process that must be cleaned to prevent system damage. The victim is then presented with a dialog box that offers to clean the computer of the problem. If the user agrees, they’re asked to run a file which is the malicious executable.
