Spin.com visitors served malware instead of music

Compromised site sent visitors to Rig exploit kit to infect them with a range of malware including Infostealer.Dyranges and Trojan.Zbot.


On October 27, while tracking exploit kits (EKs) and infected domains, Symantec discovered that the popular music news and reviews website spin.com was redirecting visitors to the Rig exploit kit. This exploit kit was discovered earlier this year and is known to be the successor of another once popular EK, Redkit. The Rig EK takes advantage of vulnerabilities in Internet Explorer, Java, Adobe Flash, and Silverlight and was also one of the EKs associated with the askmen.com compromise back in June.

At the time of writing, the spin.com website was no longer compromised. However, spin.com is a popular site in the US, according to Alexa, so the attackers could have potentially infected a substantial amount of users’ computers with malware during the time the site was compromised. The number of potential victims could grow substantially depending on the length of time the website was redirecting visitors to the EK prior to our discovery. Our data shows that the attack campaign mainly affected spin.com visitors located in the US.

How the attack worked
The attackers injected an iframe into the spin.com website, which redirected users to the highly obfuscated landing page of the Rig EK.

When the user arrives on the landing page, the Rig EK checks the user’s computer for driver files associated with particular security software products. To avoid detection, the EK avoids dropping any exploits if the security software driver files are present.

The EK then looks for particular installed plugins and will attempt to exploit them accordingly. In the recent compromise, the Rig EK took advantage of the following vulnerabilities:

Upon successfully exploiting any of these vulnerabilities, a XOR-encrypted payload is downloaded onto the user’s computer. The Rig EK may then drop a range of malicious payloads such as downloaders and information stealers including banking Trojan Infostealer.Dyranges, and the infamous Trojan.Zbot (Zeus).

Symantec protection
Symantec has detections in place to protect against the Rig EK and the vulnerabilities exploited by it, so customers with updated intrusion prevention and antivirus signatures were protected against this attack. Users should also ensure that they update their software regularly to prevent attackers from exploiting known vulnerabilities. Symantec provides the following comprehensive protection to help users stay protected against the Rig EK and the malware delivered by it in this recent website compromise:
