Study Reveals 76% of Internet Users Vulnerable to Browser History Detection

A recent study reveals a browser history detection method, largely dismissed as an issue with minimal impact, can in fact be used against a vast majority of Internet users with significant malicious potential. Researchers, Artur Janc and Lukasz Olejnik, analyzed real-world results obtained from 271,576 Internet users and have reported the results in a paper titled, "Feasibility and Real-World Implications of Web Browser History Detection".

ICANN Security Team Reports on Conficker Post-Discovery Analysis

A paper released today by ICANN provides a chronology of events related to the containment of the Conficker worm. The report, "Conficker Summary and Review," is authored by ICANN's Dave Piscitello, Senior Security Technologist on behalf of the organization's security team.

Fake Anti-Virus Peddlers Taking Aggressive Steps to Avoid Detection

Over at Krebs on Secrity blog, Brian Krebs reports: "Purveyors of fake anti-virus or 'scareware' programs have aggressively stepped up their game to evade detection by legitimate anti-virus programs, according to new data from Google. In a report being released today, Google said that between January 2009 and the end of January 2010, its malware detection infrastructure found some 11,000 malicious or hacked Web pages that attempted to foist fake anti-virus on visitors."

Botnet Takedowns Having Limited Impact on Overall Spam Volumes, Says Google

Google, which through its Postini email security and archiving service processes over 3 billion email connections a day, reports that despite recent series of major botnet takedowns, spam levels during the first quarter of 2010 have held fairly steady. "This suggests that there's no shortage of botnets out there for spammers to use. If one botnet goes offline, spammers simply buy, rent, or deploy another, making it difficult for the anti-spam community to make significant inroads in the fight against spam with individual botnet takedowns."

Malware and Botnet Operators Setting Up Their Own Data Centers

Dennis Fisher of Thread Post reports: "The malware writers and criminals who run botnets for years have been using shared hosting platforms and so-called bulletproof hosting providers as bases of operations for their online crimes. But, as law enforcement agencies and security experts have moved to take these providers offline, the criminals have taken the next step and begun setting up their own virtual data centers."

Vietnam Primary Source of Spam in November

Vietnam is now responsible for more than 10% of the worlds spam, according to threat analysis from managed security firm, Network Box. November saw malware threat levels remain consistently high with Vietnam taking the number one spam spot from last month’s chart topper, Brazil.

60 Minutes Investigates Cybersecurity and the Reality of Sabotaging Critical Infrastructure

CBS's 60 Minutes aired a special report last night investigating how hackers can get into the computer systems that run crucial elements of the world's infrastructure, such as the power grids, water works or even a nation's military arsenal. From the report: "At the Sandia National Laboratories, Department of Energy security specialists like John Mulder try to hack into computer systems of power and water companies, and other sensitive targets in order to figure out the best way to sabotage them. It's all done with the companies' permission in order to identify vulnerabilities. In one test, they simulated how they could have destroyed an oil refinery by sending out code that caused a crucial component to overheat."

APWG: The Internet Has Never Been More Dangerous

Anti-Phishing Working Group (APWG) released its latest Phishing Activity Trends Report today warning that the number of unique phishing websites detected in June rose to 49,084, the highest since April, 2007's record of 55,643, and the second-highest recorded since APWG began reporting this measurement. "The number of hijacked brands ascended to an all-time high of 310 in March and remained, in historical context, at an elevated level to the close of the half in June," says the report.

Google Exec: ISPs Must Get Tough on Malware Infested Computers on Their Networks

Ryan Naraine reporting at Threatpost: "Head of Google's anti-malvertising team Eric Davis wants Internet Service Providers (ISPs) to look beyond profits and take a more proactive approach to dealing with malware-infested computers on their networks. During a keynote presentation at the Virus Bulletin conference here, Davis said competitors in the ISP space must look beyond profits and partner on new initiatives to deal with the "parasites" that have taken control of the Internet landscape."

Latest Study Suggests Computers Remain Infected Far Longer Than Previously Suggested

Contrary to previous security reports suggesting compromised machines remain infected for 6 weeks, experts at Trend Micro say these estimates are far from accurate. In its recent blog post the company said: "During the analysis of approximately 100 million compromised IP addresses, we identified that half of all IP addresses were infected for at least 300 days. That percentage rises to eighty percent if the minimum time is reduced to a month." Additionally the study also indicates that while three quarter of the IP addresses were linked to consumer users, the remaining quarter belonged to enterprise users.

Latvian ISP Closure Dents Cutwail Botnet ...for a Whole 48 Hours

From MessageLabs' latest report: "Real Host, an ISP based in Riga, Latvia was alleged to be linked to command-and-control servers for infected botnet computers, as well as being linked to malicious websites, phishing websites and 'rogue' anti-virus products. Real Host was disconnected by its upstream providers on 1 August 2009. The impact was immediately felt, where spam volumes dropped briefly by as much as 38% in the subsequent 48-hour period. Much of this spam was linked to the Cutwail botnet, currently one of the largest botnets and responsible for approximately 15-20% of all spam. Its activity levels fell by as much as 90% when Real Host was taken offline, but quickly recovered in a matter of days."

Apparently Legitimate Estonian ISP Operating as Large Cybercrime Hub Since 2005

An apparently legitimate ISP in Tartu, Estonian is reported to have been serving as the operational headquarters of a large cybercrime network since 2005 according to TrendWatch, the security research arm of TrendMicro. "An Estonian company is actively administering a huge number of servers in numerous datacenters, which together form a network to commit cybercrime. It appears that the company from Tartu, Estonia controls everything from trying to lure Internet users to installing DNS changer Trojans by promising them special video content, and finally to exploiting victims' machines for fraud with the help of ads and fake virus infection warnings..."

MAAWG Issues ISP Guidelines for End-User Bot Removal

Messaging Anti-Abuse Working Group (MAAWG) has issued the first best practices aimed at helping the global ISP industry work more closely with consumers to recognize and remove bot infections on end-users' machines. The paper outlines a three-step approach with recommendations for detecting bots, notifying users that their computers have been compromised, and guiding them in removing the malware.

Survey Suggests Strained Budgets Causing Security Cutbacks on Known Threats

A recent survey of security professionals by RSA Conference with regards to critical security threats and infrastructure issues currently faced, revealed budgetary constrains as the top challenge currently faced. According to reports, the study suggests that even though practitioners are most concerned about email phishing and securing mobile devices, technologies addressing these needs are at risk of being cut from IT budgets. 72% percent of respondents indicated a rise in email-borne malware and phishing attempts since Fall 2008, with 57% stating they have seen an increase in Web-borne malware. Concerns about zero-day attacks and rogue employees as a result of layoffs were cited by 28% and 26% of survey respondents, respectively.
