Counter-eCrime Operations Summit (APWG) In Prague Next Week

The sixth annual Counter-eCrime Operations Summit (CeCOS VI) will engage questions of operational challenges and the development of common resources for the first responders and forensic professionals who protect consumers and enterprises from the ecrime threat every day. This year's meeting will focus on the shifting nature of cybercrime and the attendant challenges of managing that dynamic threatscape.

Mac Hit by Another Wave of Malware… Users in Denial?

In case you haven't been watching cyber news recently, last week various security researchers published that Macs were infected by the Flashback Trojan and that the total number of infections worldwide was 600,000. This number was published by a couple of blogs. I debated writing about this topic since we had a previous Mac outbreak last year that initially spiked up, caused Apple to go into denial about the affair before issuing a fix, and then the malware kind of went away. Will this follow the same pattern?

Global Payments Breach Confirmation

This morning, Global Payments held a conference call with investors and analysts covering their earlier breach announcement and projected earnings. Global Payments had also released an update advisory yesterday stating that "the company believes that the affected portion of its processing system is confined to North America and less than 1,500,000 card numbers have been exported" and that only Track 2 card data may have been stolen.

The Take Away from Global Payments Breach

Global Payments, an Atlanta-based payment card processing firm, announced yesterday that they had suffered "unauthorized access into a portion of its processing system". Sometime in early March they uncovered the attack, and there are some indications that the breach occurred between January 21st and February 25th of this year... There are a number of unverified reports that a New York City street gang with Central American ties took control of "an administrative account that was not protected sufficiently".

Kelihos Is Dead: Long Live Kelihos

The King is dead. Long live the King! Or, given this week's events, should the phrase now be "Kelihos is dead. Long live Kelihos"? It is with a little amusement and a lot of cynicism that I've been watching the kerfuffle relating to the latest attempt to take down the Kelihos botnet. You may remember that a similar event ("Kelihos is dead") occurred late last year after Microsoft and Kaspersky took it on themselves to shut down the botnet known as Kelihos (or sometimes as Waledac 2.0 or Hlux).

Household Botnet Infections

Pinning down the number of infected computers is really, really hard. I'd go as far as saying it's practically impossible to calculate, let alone observe. Still, that's not going to stop people from attempting to guess or extrapolate from their own observations. Over the years I've heard "reliable" numbers ranging from 10% through to 60% -- and I don't trust any of them. There's a whole gaggle of reasons why the numbers being thrown out to the public are inaccurate and should ideally be interpreted with a lot of skepticism by any right-minded folks.

Microsoft Disrupts the Zeus Infrastructure

Over the weekend and this morning, Microsoft, working in conjunction with others, issued civil lawsuits to sinkhole numerous domains associated with the Zeus botnet. When I say "botnet", I use the term loosely because Zeus is not a botnet in the sense that Rustock or Waledac is (or was). Rather, Zeus is a tool kit that online criminals can buy that lets them create phishing pages, perform fast fluxing, host drive-by downloads in addition to spamming. It's more like infrastructure than a botnet, although it does have a large botnet under its control.

The Top 3 Emerging Threats on the Internet

Last week at RSA, Bruce Schneier gave a talk on the top 3 emerging threats on the Internet. Whereas we in the security field usually talk about spam, malware and cyber crime, he talked about three meta-trends that all have the potential to be more dangerous than the cybercriminals. Here are my notes.

Most Abusive Domain Registrations are Preventable

As the WHOIS debate rages and the Top-Level Domain (TLD) space prepares to scale up the problem of rogue domain registration persists. These are set to be topics of discussion in Costa Rica. While the ICANN contract requires verification, in practice this has been dismissed as impossible. However, in reviewing nearly one million spammed domain registrations from 2011 KnujOn has found upwards of 90% of the purely abusive registrations could have been blocked.

Closing the Gaps: The Quest for a Secure Internet

Over the last year the world has been virtually buried under news items describing hacks, insecure websites, servers and scada systems, etc. Each and every time people seem to be amazed and exclaim "How is this possible?" Politicians ask questions, there is a short lived uproar and soon after the world continues its business as usual. Till the next incident. In this blog post I take a step back and try to look at the cyber security issue from this angle...
