"Cybercriminals constantly evolve malware and attack techniques to evade security and gain the most profit from their targets. Sixty percent of the mass-distributed malware we examined can easily slip past anti-virus software, and when that doesn't work, cybercriminals fool email recipients with phishing emails that inject malware into networks and computers at unprecedented rates," said Rob Kraus, director of SERT. "Most organizations simply don't have the internal resources needed to keep pace with modern malware attacks. To stay ahead of the threats, protect their brands and defend against breaches they need products, solutions and services that are focused purely on reducing security risks."
SERT research revealed that the majority of mass-distributed malware samples were banking Trojans, malware that uses man-in-the-browser keystroke logging to steal victim's bank account information so that it can later be used to make fraudulent charges. The most common method of delivery used for the banking Trojans was phishing emails claiming to be legitimate - such as UPS delivery confirmations, BBB complaints, flight ticket confirmations and scanned documents - that lured victims to compromised websites. Once infected, the victims' browsers were redirected, unbeknownst to them, to a Blackhole Exploit Kit landing page, which then installed additional malware, such as Zeus or Cridex.
"The malware types identified in our report impact enterprises, SMBs, government agencies and consumers," added Kraus. "They leave businesses exposed to data breaches, banks liable for millions in fraudulent charges, and consumers reeling from the impact of identity theft."
The last quarter also produced evidence of a new era in cyber espionage with the rise of advanced, modular toolkits. Flame, first discovered in May 2012, appears to have been written for espionage and has become the model for sophisticated attack toolkits. Gauss, the next toolkit to be identified, targets financial and social-media information for a specific area in the Middle East.
Late in the quarter two other trends were identified by SERT: new Zero-day exploits and increased attacks on the financial sector. The end of August brought the discovery of a Java Zero-day (CVE-2012-4681) in the wild. The exploit downloads a payload executable that resembles a Poison Ivy variant and acts as a remote access tool (RAT), allowing a remote "operator" to control a system. In September two more notably significant Zero-day vulnerabilities were observed, including one that affected Microsoft's Internet Explorer and another that had to do with Java's sandboxing mechanisms. There were also significant issues observed during the month of September regarding attacks against the financial sector. The first was financial transaction fraud conducted using malware, which in some cases was preempted or followed up by Distributed Denial of Service (DDoS) attacks. The other issue observed was DDoS attacks against a significant volume of banking websites, although these highly disruptive attacks appear to be driven by a hacktivist agenda rather than financial theft.
· Ninety-two percent of malware analyzed during the quarter was mass distributed
· Nearly 60% of all malware goes undetected by common anti-virus software
· The majority of malware samples analyzed in Q3 were banking Trojans, with Cridex taking the lead at 91%
· Only 54% of the Cridex banking Trojan samples were detected by common anti-virus software at the time of analysis
· The Blackhole Exploit Kit continued to be the most popular exploit kit used by cybercriminals
