In a presentation EU Commissioner Viviane Reding gave a preview of the new Privacy regulation her DG is preparing. As she states, privacy rules need to be brought up to date and harmonized. With all 27 member states having the same rules and tools to enforce, a company only will deal with one privacy commissioner... So, what if we, for the sake of this blog, take this initiative towards spam and cyber crime. What would this do to spam enforcement? more»
Every couple of years there's a new "hot threat" in security for which vendors abruptly tout newfangled protection and potential customers clamor for additional defense options. Once upon a time it was spyware, a few years ago it was data leakage, and today it's mobile malware. It's a reoccurring cycle, analogous to the "blue is the new black" in fashion -- if you fancy adopting a certain cynical tone. more»
A lot of pixels have been spilled in the last few years about "advanced persistent threats" (APT); if nothing else, any high-end company that has been penetrated wants to blame the attack on an APT. But what is an APT, other than (as best I can tell) an apparent codename for China? Do they exist? After thinking about it for a while, I came up with the following representation... more»

As the weeks remaining in 2011 dwindle and 2012 peaks out from behind the last page of the calendar, it must once again be that time of year for purposeful reflection and prediction. Or is that navel gazing and star gazing? At the highest level of navel gazing you could probably sum up 2011 with one word -- "More"... But let's put that aside for now. What does 2012 hold in stall for us? more»
In my last post I blogged about greylisting, a well-known anti-spam technique for rejecting spam sent by botnets. When a mail server receives a an attempt to deliver mail from an IP address that's never sent mail before, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail senders always retry, badly written spamware often doesn't. I found that even though everyone knows about greylisting, about 2/3 of IPs don't successfully retry. more»
Greylisting is a hoary technique for rejecting spam sent by botnets and other poorly written spamware. When a mail server receives an attempt to deliver mail from a hitherto unseen sending host IP address, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail software does try again, at which point you note that the host knows how to retry and you don't greylist mail from that IP again. more»
In an article on CSO.com.au a report from Sophos Australia is reported on. The anti-virus software company had bought 50 usb drives for analyses at a public transport auction of devices left on the Sydney trains. When they wrote that 66% was infected with malware, I presumed that they were left behind consciously, but were they? more»
The Virus Bulletin Conference last month had some good presentations, including this one by Fabio Assolini of Kaspersky. He spoke about how Brazil is the the newest up-and-comer on the cyber crime block. The tale begins with the story of Igor and Emily, two cyber criminals operating out of Brazil. Together, the two of them stole $300,000 US from a single Brazilian bank in one year. more»
While at that same Virus Bulletin conference that I was talking about earlier in my other post, I also had the chance to check out a session on Chinese DDoS malware put on by some folks from Arbor Networks. As little insight as I have into Android malware, I know even less about Chinese DDoS malware. So what's Chinese DDoS malware like? What are its characteristics? more»
Is desktop anti-virus dead? Someday I'd love to make that announcement, but it still feels to me that there's a Patron Saint of Voodoo with an affinity for bringing it back to life -- like some macabre mirror image of the malicious zombies it's supposed to provide protection against. It's kind of ironic that today's innovation in desktop anti-virus isn't really happening at the desktop; rather it's occurring in the cloud. more»
Last month at the Virus Bulletin Conference in Barcelona, I took in one of the sessions on mobile malware. This type of malware is foreign to me because I mostly stay in the email space at work (and even then, I am focusing more on day-to-day issues of running a large mail provider than I am on spam and abuse). What's mobile malware like? What are the threats? How do users get infected? more»
Yesterday law enforcement officials arrested 6 people and charged them with running a massive internet fraud ring. Over 4 million PCs were part of the botnet. According to the FBI, "the cyber ring used a class of malware called DNSChanger to infect approximately 4 million computers in more than 100 countries. There were about 500,000 infections in the U.S., including computers belonging to individuals, businesses, and government agencies such as NASA." more»
The last couple of years have seen a growth in commercial sinkholing operations. What was once an academic method for studying botnets and other types of Internet-born threat, has more recently turned in to an increasingly profitable business for some organizations. Yesterday I published a blog on the DarkReading site titled Sinkholing For Profit, and I wanted to expand upon some aspects of the sinkholing discussion (there's only so much you can fit in to 800-ish word limits). more»
Recent news stories (based on research by Stanford student Feross Aboukhadijeh) state that an Adobe bug made it possible for remote sites to turn on a viewer's camera and microphone. That sounds bad enough, but that's not the really disturbing part. more»
