Researcher Finds Three New Exploits Targeting Latest IE Zero-Day

A researcher at AlienVault has discovered three new servers delivering exploits targeting the latest zero-day vulnerability in Internet Explorer. Jamie Blasco, AlienVault Labs manager, said the one of the servers is delivering a new malware payload, and all of them appear to be targeting defense contractors in the United States and India.

Microsoft Recommends Workarounds to Mitigate Latest IE Zero-Day; Patch Still to Come

Microsoft issued a security advisory Monday night and recommended several workarounds to mitigate a zero-day vulnerability in Internet Explorer reported over the weekend that is being exploited in the wild. Microsoft said it is still investigating the vulnerability, and may issue an out-of-band security update to patch the problem, or wait until the next Patch Tuesday update Oct. 9.


A new version of the TDSS/TDL-4 botnet is rapidly growing, primarily because it’s having great success using an evasion technique known as a domain generation algorithm (DGA) to avoid detection, researchers at Damballa Security revealed today.The algorithm helps the latest version of the botnet carry out click-fraud campaigns and is used primarily to rapidly move communication between victims and command-and-control servers from domain to domain, a technique known as domain fluxing, similar to fast fluxing.

Forensic analysis of a number of Flame malware toolkit command-and-control servers revealed an additional three unidentified pieces of malicious code are under the control of the attackers, including one in the wild. Researchers at Kaspersky Lab, Symantec, CERT-Bund/BSI, and the International Telecommunication Union’s Impact Alliance said today they also pinpointed the first work done on the Flame espionage campaign was carried out in 2006, much earlier than the 2010 date development was initially thought to have begun.

Exploits embedded inside Microsoft Office documents such as Word, PDFs and Excel spreadsheets have been at the core of many targeted attacks during the past 24 months. Detection of these attack methods is improving and nimble hackers are recognizing the need for new avenues into enterprise networks. Some have been finding success using rich text format (RTF) files to spread malware that exploits Office vulnerabilities.

FireEye reported today it had detected a new critical PDF attack targeting the aviation defense industry. Malware Page exploits a stack-based buffer overflow vulnerability in Adobe Acrobat and Adobe Reader. An attacker would be able to execute code remotely via a crafted argument to the getIcon method of a Collab object, according to the CVE alert.

A botnet known as Nitol, built on the backs of PCs and laptops loaded with malware somewhere in the supply chain, was taken down by Microsoft. Microsoft’s Digital Crimes Unit was given permission this week by the U.S. District Court for the Eastern District of Virginia to take over the 3322.org domain and more than 70,000 sub-domains hosting the Nitol botnet.
