DDoS-for-Hire Service Webstresser Dismantled

April 25, 2018

Authorities in the U.S., U.K. and the Netherlands on Tuesday took down popular online attack-for-hire service WebStresser.org and arrested its alleged administrators. Investigators say that prior to the takedown, the service had more than 136,000 registered users and was responsible for launching somewhere between four and six million attacks over the past three years.

Deleted Facebook Cybercrime Groups Had 300,000 Members

April 16, 2018

Hours after being alerted by KrebsOnSecurity, Facebook last week deleted almost 120 private discussion groups totaling more than 300,000 members who flagrantly promoted a host of illicit activities on the social media network’s platform. The scam groups facilitated a broad spectrum of shady activities, including spamming, wire fraud, account takeovers, phony tax refunds, 419 scams, denial-of-service attack-for-hire services and botnet creation tools. The average age of these groups on Facebook’s platform was two years.

Powerful New DDoS Method Adds Extortion

March 2, 2018

Attackers have seized on a relatively new method for executing distributed denial-of-service (DDoS) attacks of unprecedented disruptive power, using it to launch record-breaking DDoS assaults over the past week. Now evidence suggests this novel attack method is fueling digital shakedowns in which victims are asked to pay a ransom to call off crippling cyberattacks.

Correcting the Record on vDOS Prosecutions

November 21, 2017

KrebsOnSecurity recently featured a story about a New Mexico man who stands accused of using the now-defunct vDOS attack-for-hire service to hobble the Web sites of several former employers. That piece stated that I wasn’t aware of any other prosecutions related to vDOS customers, but as it happens there was a prosecution in the United Kingdom earlier this year of a man who’s admitted to both using and helping to administer vDOS. Here’s a look at some open-source clues that may have led to the U.K. man’s arrest.

Stress-Testing the Booter Services, Financially

August 17, 2015

The past few years have witnessed a rapid proliferation of cheap, Web-based services that troublemakers can hire to knock virtually any person or site offline for hours on end. Such services succeed partly because they’ve enabled users to pay for attacks with PayPal. But a collaborative effort by PayPal and security researchers has made it far more difficult for these services to transact with their would-be customers.

Spreading the Disease and Selling the Cure

January 26, 2015

When Karim Rattani isn’t manning the till at the local Subway franchise in his adopted hometown of Cartersville, Ga., he’s usually tinkering with code. The 21-year-old Pakistani native is the lead programmer for two very different yet complementary online services: One lets people launch powerful attacks that can knock Web sites, businesses and other targets offline for hours at a time; the other is a Web hosting service designed to help companies weather such assaults.

Another Lizard Arrested, Lizard Lair Hacked

January 16, 2015

Several media outlets are reporting that authorities in the United Kingdom early this morning arrested an 18-year-old in connection with the denial-of-service attacks on Sony Playstation and Microsoft Xbox systems over Christmas. The arrest is one of several tied to a joint U.K. and U.S. law enforcement investigation into a group calling itself the “Lizard Squad,” and comes as the group’s attack-for-hire online service was completely compromised and leaked to investigators.
