Rustock, Xarvester Spambots Capable of Sending 25,000 Messages Per Hour, Says New Study

A recent study suggests Rustock and Xarvester malware provided the most efficient spambot code, enabling individual zombie computers to send 600,000 spam messages each over a 24 hour period. "Over the past few years, botnets have revolutionized the spam industry and pushed spam volumes to epidemic proportions despite the best efforts of law enforcement and the computer security industry. Our intention was to better understand the origins of spam, and the malware that drives it," said Phil Hay, senior threat analyst, TRACElabs (a research arm of security company Marshal8e6)... more

A Few More Thoughts on Email Authentication… errr… Trust

Mike Hammer's thoughtful article, A Few Thoughts on the Future of Email Authentication, should trigger thoughtfulness in the rest of us. Email abuse has been around a long time. Anti-abuse efforts have too. Yet global abuse traffic has grown into the 90+% range, with no hint of trending downward. The best we hear about current effectiveness is for last-hop filtering, if you have the money, staff and skills to apply to the problem... more

Is It Time to Supplement Desktop Security Protections?

Internet users are acutely aware of their exposure on the Internet and clearly concerned about their safety. Increased downloads of scareware as Conficker made headlines in the mainstream media are only the latest evidence. Desktop software is often viewed as a one-stop shop for fighting Internet threats such as viruses, worms and other forms of malware and phishing. These solutions have served us well but more protections are needed to address the dynamic and increasingly sophisticated web based exploits being launched... more

Asia, Europe Top the Charts on Conficker Worm Infections

Amidst hype and anticipation of the Conficker worm which is expected to become active in millions of Windows system within the next few hours, IBM Internet Security Systems team reports they have been able to locate infected systems across the world by reverse-engineering the communications mechanisms. Holly Stewart, X-Force Product Manager at IBM Internet Security Systems, writes: "... the details are still unfolding, but we can tell you from a high level where most infections are as of today. Asia tops the charts so far. By this morning, it represented nearly 45% of all of the infections from our view. Europe was second at 31%. The rest of the geographies held a much smaller percentage overall." more

Project GhostNet: Canada (and Google) Save the World from Cyber-Spying - Again!

While most people I know are at either VoiceCon or CTIA this week, this one is worth staying home for. Also, I'm sure all the Skype followers are focused today on the news about working with the iPhone -- and that IS a big story. However -- for very different reasons -- I'm sure you'll find this one of interest too. This was a front page story in today's Globe and Mail, and no doubt many other Canadian dailies... more

Worming Our Way Out of Trouble

The Conficker worm will be active again on April 1st, according to an analysis of its most recent variant, Conficker.C, by the net security firm CA.

Data Breach Costs Continue to Rise, 40% Increase Since 2005

According to a new study by PGP Corporation and Ponemon Institute, data breach incidents cost U.S. companies $202 per compromised customer record in 2008, compared to $197 in 2007. The study is based on 43 organizations across 17 different industry sectors with a range of 4,200 to 113,000 records that were affected.

Malware Detection Declining, Anti-Phishing Filters Detect Less than 50% of Attacks, Says Report

A study comparing best-of-breed computer security vendors suggests more than half of active malware and phishing threats on the Internet go undetected, with an average detection rate of 37% for malware and 42% for phishing. "Given the dynamic nature of today's online threats and the traditionally reactive approach taken by today's malware and phishing detection technology, conventional signature-based solutions are inherently at a disadvantage to keep up," said Panos Anastassiadis, CEO and Chairman of Cyveillance. "Because the majority of damage occurs during the first 24 hours of an attack, early detection of attacks is crucial." more

What Google Sees While Processing 2 Billion Enterprise Emails Per Day

While the news will not be terribly surprising to CircleID readers, Google's latest report on the status of spam and 2009 predictions posted today, might be of particular interest due to the company's shear email processing volume at 2 billion enterprise email connections per day (drawn from company owned Postini Message Security network)... more

Tough Economy Requires Knowledge and Vigilance Online

If current predictions are correct, 2009 will be a tougher year than 2008 in terms of the economy. In tough economic times such as these it becomes increasingly important for us to follow recommended safety practices when going online. As the numbers of Internet-related fraud and financial scams continue to increase we should expect the current economic situation to produce more victims of cybercrime. Knowledge and vigilance are the keys to remaining safe while online. more

Internet Population Passes 1 Billion, and We’re Still Afraid

We're learning this week that we have officially passed the one billion number in terms of people using the Internet. Eric Schonfeld writes in his article on TechCrunch that the number is probably higher than that. One billion is a staggering number, even though it makes up only 15 to 22 percent of the world's population. Nevertheless, those one billion Internet users give us a lot to deal with on their own in terms of social and security issues on the web. more

Spam Peaked at 200 Billion per Day in 2008, Botnets Nexus of Criminal Activity, Says Cisco

In a 52 page security report released by Cisco, the company has confirmed what has been consistently been observed through out this year: "the Internet-based attacks are becoming increasingly sophisticated and specialized as profit-driven criminals continue to hone their approach to stealing data from businesses, employees and consumers." The 2008 edition of the report has specified the year's top security threats and offers recommendations for protecting networks against attacks that are propagating more rapidly, becoming increasingly difficult to detect, and exploiting technological and human vulnerabilities. more
