Malware Increasingly Uses DNS As Command and Control Channel to Avoid Detection

Number of malware threats that receive instructions from attackers through DNS is expected to increase, and most companies are not currently scanning for such activity on their networks, security experts said at the RSA Conference 2012 on Tuesday. While most malware-generated traffic passing through most channels used for communicating with botnets (such as TCP, IRC, HTTP or Twitter feeds and Facebook walls) can be detected and blocked, it's not the case for DNS (Domain Name System) and attackers are taking advantage of that, said Ed Skoudis, founder of Counter Hack Challenges and SANS fellow. more

Japan Developing Distinctive Anti-Cyberattack Virus

The Japanese Defense Ministry is creating a computer virus capable of tracking, identifying and disabling sources of cyberattacks, according to reports. The development of the virtual cyberweapon was launched in 2008. Since then, the weapon has been tested in a closed network environment. "The most distinctive feature of the new virus is its ability to trace cyber-attack sources. It can identify not only the immediate source of attack, but also all "springboard" computers used to transmit the virus." more

Botnets: Most Prevalent Threat on the Internet for the Enterprises

Based on the total number of transactions, Zscaler reports botnets as the biggest security risk on the Internet for the enterprises. "Once a host gets infected, the botnet usually spreads quickly within an enterprise. It also generates a significant amount of traffic to the command and control server, to download additional malware or perform other actions." more

Typosquatted Domain Names Pose Plenty of Risk But Surprisingly Little Malware

A recent study took an in-depth look at the scale and the risk of domain name typosquatting -- the practice of registering mis-spellings of popular domain names in an attempt to profit from typing mistakes. "Applying every possible one-character typo to the domain names of Facebook, Google, Twitter, Microsoft, Apple and Sophos," Paul Ducklin, Sophos' Asia Pacific head of technology collected HTTP data and browser screenshots from 1502 web sites and 14,495 URLs. In this report, Ducklin analyses the data revealing unexpected results within the typosquatting ecosystem. more

Mobile Malware Growing Exponentially, Limited Capability of Current Security Solutions Big Concern

Security analysis suggest troubling and escalating trends in the development of malware that exploits vulnerabilities on mobile devices. "From turning mobile devices into bots, to infiltration of mobile applications, driven by the use of personal devices in the workplace, cybercriminals are taking full advantage of this market," reports M86 Security Labs in its just released Threat Predictions Report. more

Mega International DNS Malware Operation Dismantled, Reports FBI

FBI today announced six Estonian nationals have been arrested and charged with running a sophisticated Internet fraud ring that infected millions of computers worldwide with a virus and enabled the thieves to manipulate the multi-billion-dollar Internet advertising industry.

Duqu Reported as Precursor to a Future Stuxnet-Like Attack

Virus researchers at Symantec Corp. have revealed a variant of the Stuxnet worm, named Duqu, that is found to be stealing information about industrial control systems. Symantec reports: "Duqu's purpose is to gather intelligence data and assets from entities, such as industrial control system manufacturers, in order to more easily conduct a future attack against another third party. The attackers are looking for information such as design documents that could help them mount a future attack on an industrial control facility... Parts of Duqu are nearly identical to Stuxnet, but with a completely different purpose." more

OPTA revokes Diginotar License as TTP

Wout de Natris: "In this decision OPTA revokes the registration of Diginotar as a so called Trusted Third Party. Diginotar issued certified certificates for digital signatures. The security breach by Iranian hackers over the summer, which Diginotar did not report to the authorities, lead to severe credibility issues for all Diginotar certificates issued before. This included Dutch government websites, but also led to severe breaches of privacy for Iranian end users, in multiple countries. As a result of OPTA's decision all certificates issued by Diginotar have to be revoked, while at the same she is forbidden to issue new ones. more

New Research Reveals 56% Rise in Cost of Cybercrime

New research indicates cyberattacks increasingly plague businesses and government organizations, resulting in significant financial impact, despite widespread awareness. Conducted by the Ponemon Institute, the Second Annual Cost of Cyber Crime Study revealed that the median annualized cost of cybercrime incurred by a benchmark sample of organizations was $5.9 million per year, with a range of $1.5 million to $36.5 million each year per organization. This represents an increase of 56 percent from the median cost reported in the inaugural study published in July 2010. more

Automated Web Application Attacks Can Peak at 25,000 an Hour

Web applications, on average, experience twenty seven attacks per hour, or roughly one attack every two minutes, according to the newly released Imperva Web Application Attack Report. Report also notes that when websites came under automated attack they received up to 25,000 attacks in one hour, or 7 attacks every second. more
