Who Wrote the Flashback OS X Worm?

April 3, 2013

A year ago today, Apple released a software update to halt the spread of the Flashback worm, a malware strain that infected more than 650,000 Mac OS X systems using a vulnerability in Apple’s version of Java. This somewhat dismal anniversary is probably as good a time as any to publish some clues I’ve gathered over the past year that point to the real-life identity of the Flashback worm’s creator.

Fool Me Once…

April 2, 2013

When you’re lurking in the computer crime underground, it pays to watch your back and to keep your BS meter set to ‘maximum.’ But when you’ve gained access to an elite black market section of a closely guarded crime forum to which very few have access, it’s easy to let your guard down. That’s what I did earlier this year, and it caused me to chase a false story. This blog post aims to set the record straight on that front, and to offer a cautionary (and possibly entertaining) tale to other would-be cybersleuths.

The Obscurest Epoch is Today

March 18, 2013

To say that there is a law enforcement manhunt on for the individuals responsible for posting credit report information on public figures and celebrities at the rogue site exposed.su would be a major understatement. I like to think that when that investigation is completed, some of the information I’ve helped to uncover about those affiliated with the site will come to light. For now, however, I’m content to retrace some of my footwork this past weekend that went into tracking individuals who may have been responsible for attacking my site and SWATing my home last Thursday.

The World Has No Room For Cowards

March 15, 2013

It’s not often that one has the opportunity to be the target of a kinetic and cyber attack at the same time. But that is exactly what’s happened to me and my Web site over the past 24 hours. On Thursday afternoon, my site was the target of a fairly massive denial of service attack. That attack was punctuated by a visit from a heavily armed local police unit that was tricked into responding to a 911 call spoofed to look like it came from my home.

A Closer Look at Two Bigtime Botmasters

December 11, 2012

Over the past 18 months, I’ve published a series of posts that provide clues about the possible real-life identities of the men responsible for building some of the largest and most disruptive spam botnets on the planet. I’ve since done a bit more digging into the backgrounds of the individuals thought to be responsible for the Rustock and Waledac spam botnets, which has produced some additional fascinating and corroborating details about these two characters.

Infamous Hacker Heading Chinese Antivirus Firm?

November 14, 2012

What does a young Chinese hacker do once he’s achieved legendary status for developing Microsoft Office zero-day exploits and using them to hoover up piles of sensitive data from U.S. Defense Department contractors? Would you believe: Start an antivirus firm?

That appears to be what’s happened at Anvisoft, a Chinese antivirus startup that is being somewhat cagey about its origins and leadership. I stumbled across a discussion on the informative Malwarebytes user forum, in which forum regulars were scratching their heads over whether this was a legitimate antivirus vendor. Anvisoft had already been whitelisted by several other antivirus and security products (including Comodo), but the discussion thread on Malwarebytes about who was running this company was inconclusive, prompting me to dig deeper.

‘Project Blitzkrieg’ Promises More Aggressive Cyberheists Against U.S. Banks

October 8, 2012

Last week, security firm RSA detailed a new cybecriminal project aimed at recruiting 100 botmasters to help launch a series of lucrative online heists targeting 30 U.S. banks. RSA’s advisory focused primarily on helping financial institutions prepare for an onslaught of more sophisticated e-banking attacks, and has already received plenty of media attention. I’m weighing in on the topic because their analysis seemed to merely scratch the surface of a larger enterprise that speaks volumes about why online attacks are becoming bolder and more brash toward Western targets.

Inside the Grum Botnet

August 20, 2012

KrebsOnSecurity has obtained an exclusive look inside the back-end operations of the recently-destroyed Grum spam botnet. It appears that the crime machine was larger and more complex than many experts had imagined. It also looks like my previous research into the identity of the Grum botmaster was right on target.

Harvesting Data on the Xarvester Botmaster

August 6, 2012

In February, I published the results of an investigation into the identity of the man behind the once-infamous Srizbi spam botnet. Today’s post looks at the individual(s) likely involved in running the now-defunct Xarvester botnet, a spam machine that experts say appeared shortly after Srizbi went offline and shared remarkably similar traits.

Srizbi was also known in the underground as “Reactor Mailer,” and customers could register to spam from the crime machine by logging into accounts at reactormailer.com. That domain was registered to a mserver@mail.ru, an address that my reporting indicates was used by a Philipp Pogosov; more commonly known by his nickname SPM, Pogosov was a top moneymaker for SpamIt, a rogue online pharmacy affiliate program that was responsible for a huge percentage of junk email over the past half-decade.

Who Is the ‘Festi’ Botmaster?

June 13, 2012

Pavel Vrublevsky, the co-founder of Russian payment processor ChronoPay, is set to appear before a judge this week in a criminal case in which he is accused of hiring a botmaster to attack a competitor. Prosecutors believe that the man Vrublevsky hired in that attack was the curator of the Festi botnet, a spam-spewing machine that also has been implicated in a number of high-profile denial-of-service assaults.
