Botnet Hiding Commands as JPEG Images

Security researchers have stumbled on a new botnet that uses an interesting technique to mask its nefarious intentions.
The Monkif/DIKhora botnet, which is pushing out Trojan downloaders to infected machines, is encoding the instructions to appear as if the command-and-control server is returning a JPEG image file, according to SecureWorks researcher Jason Milletary.  Read the full story [secureworks.com]

GENEVA — In a sign that cyber-criminals are investing more time and resources into attacks against Apple’s Mac users, a new malware affiliate program has been discovered offering 43c for every infected Mac machine.
During an eye-opening presentation at the VB Conference 2009 conference here, Sophos Labs researcher Dmitry Samosseikko provided a glimpse into the “Partnerka,” a Russian network of spam and malware affiliates that have turned their attention to the Mac platform — using social engineering tricks to load fake codecs and scareware programs.

The IDG News Service is reporting on a new FBI investigation [computerworld.com] of a rash of online hacking attacks and bank robberies against school districts in Illinois.

FBI investigators are working on a computer intrusion case at the Crystal Lake School District in Crystal Lake, Illinois, said Ross Rice, a spokesman with the FBI’s Chicago office. But several other school districts also believe that they have been hit by the same malicious software, Rice said.  The Clampi malware family [secureworks.com] may  be linked to these attacks.

In the never-ending battle to protect computer networks from intruders, security experts are deploying a new defense modeled after one of nature’s hardiest creatures — the ant.
Unlike traditional security devices, which are static, these “digital ants” wander through computer networks looking for threats, such as “computer worms”  — self-replicating programs designed to steal information or facilitate unauthorized use of machines. When a digital ant detects a threat, it doesn’t take long for an army of ants to converge at that location, drawing the attention of human operators who step in to investigate.  Read the full story [wfu.edu]
