Newsletters: @RISK


@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

TOP VULNERABILITY THIS WEEK: The .cn TLD was hit by what Chinese authorities described as the country's "largest-ever" DDoS attack over the weekend, disrupting service there for approximately four hours. The attack, whose source is so far unknown, highlights the vulnerability of the modern Internet to flooding attacks, which have been a growing scourge for financial institutions, governments, and others in the last few years.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: China suffers "largest-ever" DDoS attack
Description: An attack on the .cn registry and associated DNS services hit at midnight Sunday local time this weekend, taking out service for a large swath of the Chinese portion of the Internet. The outage, which prompted an official apology from the state-run China Internet Network Information Center, was described as the biggest attack to ever hit the country's core infrastructure. The source of the attacks is unclear at this point, with some arguing that even a single unknown individual may have been responsible.

Snort SID: N/A
ClamAV: N/A

Title: New Android malware sample uses SMTP to send mail
Description: While most Android malware uses some combination of SMS, HTTP, and/or a custom binary protocol to communicate with the outside world, a recently discovered sample from China uses SMTP to send stolen data to its controllers. This novel technique illustrates the growing complexity of Android malware, which continues to thrive in third-party markets, particularly in Asia.

Snort SID: 27725
ClamAV: ANDR.Trojan.SMSAgent-1

Title: New version of DirtJumper malware adds anti-DDoS tool features
Description: In an excellent illustration of the ongoing cat-and-mouse game between malware creators and network defenders, a new version of the popular DirtJumper DDoS software was recently released which intelligently probes for the presence of certain types of network defense tools. While security vendors are responding by updating their detection mechanisms, such measures are reactive at best, and will necessarily suffer from coverage gaps when further updates to the toolset are released.
