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

Implications of California Telecom Attack Gone Un-Reported

In an article titled "A Cyber-Attack on an American City", Bruce Perens writes: "Just after midnight on Thursday, April 9, unidentified attackers climbed down four manholes serving the Northern California city of Morgan Hill and cut eight fiber cables in what appears to have been an organized attack on the electronic infrastructure of an American city. Its implications, though startling, have gone almost un-reported. That attack demonstrated a severe fault in American infrastructure: its centralization. The city of Morgan Hill and parts of three counties lost 911 service, cellular mobile telephone communications, land-line telephone, DSL internet and private networks, central station fire and burglar alarms, ATMs, credit card terminals, and monitoring of critical utilities..." 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

Security Researchers Uncover Cyber Espionage Network Invloving 103 Countries

A report released over the weekend by Information Warfare Monitor along with an exclusive story by the New York Times, revealed a 10-month investigation of a suspected cyber espionage network (dubbed GhostNet) of over 1,295 infected computers in 103 countries. 30% of the infected computers are labeled as high-value targets, including ministries of foreign affairs, embassies, international organizations, news media, and NGOs. Greg Walton, editor of Information Warfare Monitor and a member of the Toronto academic research team that is reporting on the spying operation, writes... more

DNS Insecurity

The Internet as we know it and use it today -- is broken, badly broken. Yes broken so much so that we are really crazy to have any expectations of privacy or security. Yes, really. The Internet was conceived as somewhat of a utopian environment, one where we all keep our doors, windows and cars unlocked and we trust all the people and machines out there to "do the right thing...". 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. Maxim Weinstein, manager of StopBadware.org at Harvard University's Berkman Center for Internet & Society, says the site is not only a useful destination, but also a piece of a bigger puzzle. "BadwareBusters.org is part of StopBadware's strategy to bring together the people, the organizations, and the data that allow us to fight back against the spread of badware," Weinstein said. "The collective wisdom of the BadwareBusters community will inform not only individuals, but the entire technology industry." more

U.S. Cyber Security: Blurred Vision

It has been beaten, butted, and batted around quite a bit in the past few weeks -- let's look at a rough timeline of political issues which bring me to this point. Let's look at the power struggle (I prefer to call it confusion) in the U.S. Government with regards to "Cyber Security" -- in a nutshell. In the latter part of 2008, the U.S. House of Representatives Homeland Security Committee determined that DHS was not capable of providing proper critical infrastructure protection (and other Cyber protection capabilities) due to a number of issues. This may well be a political maneuver, or it may well actually have merit. more

C-SPAN Interview: Internet and Cybersecurity

C-SPAN interviews professor Gene Spafford from Purdue University on the topic of cybersecurity and how the current Internet is a conduit for all types of "cybercrime". He also talks about the much discussed article "A New Internet?" by John Markoff in the February 14, 2009, New York Times in which he was quoted. The piece argued for a new type of Internet that is more secure with the trade-off of users giving up more of their anonymity. Professor Spafford talks about alternative solutions and he responded to questions via telephone calls and email. more

An Economic Outlook on Information Security
