Brazil: The Newest Up and Comer

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

Water Supply System Apparently Hacked, with Physical Damage

According to press reports, a water utility's SCADA network was hacked. The attacker turned a pump on and off too much, resulting in physical damage to the pump. ... For years, security specialists have been warning that something like this could happen. Although more and more people have started to believe it, we still hear all of the usual reassuring noises -- the hackers don't know enough, we have defenses, there are other safeguards, etc. That debate is now over... more

What Chinese DDoS Malware Looks Like

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

Taking the Leap to Cloud-Based Malware Inspection

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

What Mobile Malware Looks Like

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

Biggest Botnet Takedown to Date

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

ICANN: The Stakes in Registrar Accreditation

Law enforcement demands to domain name registrars were a recurring theme of the 42d ICANN public meeting, concluded last week in Dakar. The Governmental Advisory Committee (GAC) took every opportunity at its public meetings with GNSO and Board, and in its Communique to express dismay, disappointment, and demands for urgent action to "reduce the risk of criminal abuse of the domain name system." more

New Threats Demand a New Approach to DDoS Protection

In the past 24 months, distributed denial of service (DDoS) attacks have changed profoundly. Gone are the days when attackers worked under the radar, when machines were infected by botnet code unknowingly and attacks were disguised leaving very little to trace the exact origin. ... The other game-changer: It's easier than ever to execute attacks. The tools are so widely available that anyone with basic skills and a high-speed connection can become a "hacktivist." more

Growth in Commercial Sinkholing Operations

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

The Sins of the Flash

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
