Wonknu: A Spy For The 3rd ASEAN-US Summit

概要

In the era of APT’s, it feels like something is amiss when there is a forum of governments and no malware arises. But the 3rd ASEAN-United States Summit on 21 November 2015 did not disappoint. A few days before the Kuala Lumpur summit, a subdomain under asean.org for the ASEAN Secretariat Resource Centre (ARC) was compromised. Malicious code was appended to the compromised script file, which redirected a visitor. While still compromised, the ARC website also hosted an archive with the filename: the 3rd ASEAN Defence Ministers’ Meeting.rar. This contained malware that we detect as Backdoor:W32/Wonknu.A.
