On Tuesday May 28, 2013 at 17:30 UTC a massive pharmaceutical-based spam campaign began, using the Subject: header “Only 24 Hours Left to Shop!”. Cisco witnessed volume rates peaking as high as 8 out of every 10 spam messages being sent. The indiscriminate nature of the attack’s recipients suggests that most anti-spam vendors, including Cisco, will have blocked this attack very quickly.

In the days leading up to #OpUSA, security professionals were busy making preparations for the supposed flood of new attacks coming on 7 May 2013.

In other cases, they are enhanced by increased publicity. By 4 May 2013, speculation arose that #OpUSA was a trap; this likely caused some potential participants to rethink their plans to join. Posts similar to the one below were made on Twitter, Facebook, and YouTube. Read More »
“Watering Hole” attacks, as evidenced by the recent attack involving the U.S. Department of Labor, are becoming increasingly popular as alternatives to attacks such as Spear Phishing. In a “Watering Hole” attack, the attacker compromises a site likely to be visited by a particular target group, rather than attacking the target group directly. Eventually, someone from the targeted group visits the “trusted” site (A.K.A. the “Watering Hole”) and becomes compromised.
Cisco identified suspicious GET requests made to the www.sellagreement.com, a malicious site which was recently linked with the Department of Labor attack. According to the evidence we have, the sites www.kforce.com and www.sbc.net were among those compromised during this attack. The webpages that were serving malicious content from these sites were mostly job-search related, but several requests to www.sellagreement.com lacked a “Referrer:” HTTP header entirely. Read More »
