Amnesty International’s UK website has been compromised and is serving drive-by downloads. Historical data indicates the website AIUK was compromised on or before Friday, December 16.
Visiting hxxp://www[.]amnesty[.]org[.]uk loads hxxp://3max[.]com[.]br/cgi-bin/ai/ai.html via an iframe. 3max.com.br, which itself is a legitimate but compromised Brazilian automotive website, loads malicious Java content (stolen from the Metasploit project), which targets CVE-2011-3544. If the exploit is successful, malware is installed on the visitor’s system.

The exploit payload possesses properties of targeted malware but is being served by an exploit of a popular, public website. The working theory for this anomaly relates to Amnesty International as a human rights non-governmental organization. To explain, certain countries use zero day exploits and other techniques to gain electronic information about the activities of human rights activists. Of course, a subset of these activists are too smart to click on links in even well-worded spear phishing emails. But what if you compromised a website frequented by these activists (e.g., Amnesty International)? Then your targets come to you. The context-specific damage potential is significant.
Amnesty International UK has been notified about the compromise.
