Fortinet Threatscape Report Shows Botnets Battling for Digital Real Estate

Fortinet® (NASDAQ: FTNT) - a leading network security provider and worldwide leader of unified threat management (UTM) solutions – today announced its April 2010 Threatscape report, which showed high activity from the Gumblar and Sasfis botnets.

While Gumblar remained in the No. 1 position in Fortinet’s Top 10 Network Attacks list, the Sasfis botnet had two of its executables appear in Fortinet’s Antivirus Top 10 listing. Like Bredolab, Sasfis is a botnet loader that reports statistics, and retrieves/executes files upon check-in. However, Sasfis differs by being newer, and does not employ encryption for communications. Sasfis continues to spread aggressively, and is typically used to load banking trojans onto unsuspecting people’s computers.

Additional key threat activities for the month of April include:

* Microsoft Vulnerabilities: The Internet Explorer vulnerability MS.IE.Userdata.Behavior.Code.Execution (CVE-2010-0806) was the second-most detected malicious network activity for the second report in a row. While in its zero-day state, Fortinet observed attacks on this vulnerability that installed the infamous Gh0st RAT spy-trojan, a fully-functioning remote administration tool that also streams Webcam video and audio feeds. FortiGuard Labs also discovered two new memory corruption vulnerabilities in Microsoft Office Visio that allow a remote attacker to compromise a system through a malicious document. The vulnerabilities are triggered when opening and rendering a Visio file. A remote attacker could craft a malicious document that exploits either one of these vulnerabilities, allowing them to compromise a system.

* Adobe Acrobat vulnerabilities: Fortinet’s FortiGuard Labs discovered two new memory corruption vulnerabilities in Adobe Reader / Acrobat, which allow a remote attacker to compromise a system through a malicious document. The vulnerabilities are triggered when opening and rendering a PDF document. A remote attacker could craft a malicious document which exploits either one of these vulnerabilities, allowing them to compromise a system.

* Ransomware and Scareware still top virus detection: This is no surprise, as Scareware has been consistently prevalent since September 2008. Ransomware, on the other hand, began making headway in 2010 due to incentives from affiliate-backed programs that pay out when victims purchase the fake products.

* Cutwail spambot leveraged for money mule recruitment: Fortinet continues to observe the Cutwail spambot, which has been active for years, send various spam campaigns on behalf of its customers. The spam sent by Cutwail this month typically included malicious links to eCard binaries, or emails with the binaries themselves attached. There were various money mule recruitment themes observed in spam emails in April, showing a growing demand for jobs on the black market.

“Money mules are essentially money laundering vehicles used by cyber criminals to handle and transfer illicit funds,” said Derek Manky, project manager, cyber security and threat research, Fortinet. “The mule receives a commission for doing the transfer. These transfers are typically done in batches of $10,000 USD or less. Money mule positions are, more times than not, crafted as legitimate sounding jobs, such as accounts receivable positions. If something seems too good to be true, it generally is.”
