MIDDLE EAST, February 6, 2011 – Fortinet® (NASDAQ: FTNT) – a leading network security provider and the worldwide leader of unified threat management (UTM) solutions – today announced its January 2011 Threat Landscape report, which identifies a 61 percent exploitation rate of new vulnerabilities found this period and tracked by FortiGuard Labs. On a typical month, exploit activity falls between 30 percent and 40 percent. Half of new vulnerabilities rated as “critical” were targeted, opening doorways for an attacker to execute any command(s) on a target machine.
“It is no secret that software vulnerabilities continue to be disclosed in large numbers on an ongoing basis – especially critically rated ones,” said Derek Manky, senior security strategist at Fortinet’s FortiGuard Labs. “Hackers are sinking their teeth into unprotected systems, thanks to readily available exploit code and attack frameworks that support these new vulnerabilities. Since they are freshly disclosed, not everyone may have up-to-date signatures or proper patches in place. It is imperative to ensure both are updated in a timely fashion in order to effectively combat this threat. Also, with the use of communication through common protocols, application control is becoming more important in identifying malicious activity on the application level.”
Top Three Malware Detections for the Month
Two Virut variants surfaced during this report period and, as of this writing, they are still receiving commands from Virut controllers to download and execute malware. Virut.U uses an updated IRC channel and encrypts all traffic to this IRC channel, while Virut.A continues to connect to the IRC server unencrypted. Both variants are using port 65520 for connection. Virut, which has been around since 2006 and has been in Fortinet’s Top 10 and Top 100 lists ever since, is a rigid file infector that contains a bot component, making it very difficult to clean since it spreads to thousands of files on a system once it hits. FortiGuard Labs observed Virut downloading other botnets, meaning an infected system would soon have multiple pieces of malware in place. Virut is one of the most persistent botnets the lab sees today, since it is tough to remove from an infected system, uses a public IRC domain and has hybrid spreading capabilities.
