Cyber Security and the White House

A few months ago, an article appeared on arstechnica.com asking the question "Should cybersecurity be managed from the White House?" During the recent presidential elections in the United States and the federal elections in Canada, the two major players in both parties had differing views that crossed borders. In the US, the McCain campaign tended to favor free market solutions to the problem of cybersecurity, and the Conservatives in Canada took a similar position... more

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

The Jaynes Case is Finally Over

Last September the Virginia Supreme Court issued a surprise ruling that reversed its previous decision and threw out the state’s anti-spam law on First Amendment grounds. The Commonwealth made a last ditch appeal to the US Supreme Court, which I predicted they’d be unlikely to accept. I guessed right... more

Searching for Truth in DKIM: Part 5 of 5

Throughout this series of articles we've been talking about DKIM, and what a valid DKIM signature actually means. .. What this means for senders (of any type) is that with DKIM, you’re protected. On the internet, your domain name is a statement of your brand identity – so by signing messages with DKIM, you can finally, irrevocably tie those messages to your brand. more

Searching for Truth in DKIM: Part 4 of 5

Once you've determined that you can trust the signer of a message, as we discussed in part 3, it's easy to extrapolate that various portions of the message are equally trustworthy. For example, when there's a valid DKIM signature, we might assume that the From: header isn't spoofed. But in reality, DKIM only tells us two basic things... 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. This malicious piece of software, also known as Downup, Downadup and Kido, spreads among computers running most variants of the Windows operating system and turns them into nodes on a multi-million member ‘botnet’ of zombie computers that can be controlled remotely by the worm’s as yet unidentified authors. more

StopBadware.org and Consumer Reports Launch BadwareBusters.org

StopBadware.org and Consumer Reports WebWatch have announced today the full launch of BadwareBusters.org, a new online community for people looking for help preventing and countering viruses, spyware, and other "badware" on their computers and websites.

"The collective wisdom of the BadwareBusters community will inform not only individuals, but the entire technology industry." more

Searching for Truth in DKIM: Part 3 of 5

Last year, MAAWG published a white paper titled Trust in Email Begins with Authentication [PDF], which explains that authentication (DKIM) is “[a] safe means of identifying a participant-such as an author or an operator of an email service” while reputation is a “means of assessing their trustworthiness.”

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

X-Force Report: Corporations Becoming No. 1 Security Threat to Their Own Customers

With the alarming increase in cyberattacks, criminals are literally turning businesses against their own customers in order to steal consumer's personal data, warns the latest annual X-Force Trend and Risk report from IBM. "The security industry puts a lot of effort into the technical evaluation of security threats, examining, sometimes at great length, the potential threat that each issue might present to corporations and consumers. Criminal attackers out for profit, however, have considerations that the security industry does not always take into account, such as monetization cost and overall profitability." 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

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
