Threat Score
The report describes an active Koobface worm campaign that leverages social engineering on social networks (fake video/Flash updates) to propagate; Zscaler observed a recent spike in unique C2 servers (about 122 IPs with a top-10 highlighted), enumerated many C&C URLs and sample malicious binaries, and recommends layered defenses (URL filtering, IDS/IPS, antivirus) while noting increased activity on weekends.
