U.S. Indicts 2 Top Russian Hackers, Sanctions Cryptex

September 26, 2024

The United States today unveiled sanctions and indictments against the alleged proprietor of Joker’s Stash, a now-defunct cybercrime store that peddled tens of millions of payment cards stolen in some of the largest data breaches of the past decade. The government also indicted a top Russian cybercriminal known as Taleon, whose cryptocurrency exchange Cryptex has evolved into one of Russia’s most active money laundering networks.

Who Stole 3.6M Tax Records from South Carolina?

April 16, 2024

For nearly a dozen years, residents of South Carolina have been kept in the dark by state and federal investigators over who was responsible for hacking into the state’s revenue department in 2012 and stealing tax and bank account information for 3.6 million people. The answer may no longer be a mystery: KrebsOnSecurity found compelling clues suggesting the intrusion was carried out by the same Russian hacking crew that stole of millions of payment card records from big box retailers like Home Depot and Target in the years that followed.

From Cybercrime Saul Goodman to the Russian GRU

February 7, 2024

In 2021, the exclusive Russian cybercrime forum Mazafaka was hacked. The leaked user database shows one of the forum’s founders was an attorney who advised Russia’s top hackers on the legal risks of their work, and what to do if they got caught. A review of this user’s hacker identities shows that during his time on the forums he served as an officer in the special forces of the GRU, the foreign military intelligence agency of the Russian Federation.

$10M Is Yours If You Can Get This Guy to Leave Russia

May 4, 2023

The U.S. government this week put a $10 million bounty on the head of a Russian man who for the past 18 years operated Try2Check, one of the cybercrime underground’s most trusted services for checking the validity of stolen credit card data. U.S. authorities say 43-year-old Denis Kulkov’s card-checking service made him at least $18 million, which he used to buy a Ferrari, Land Rover, and other luxury items.

Lawmakers Probe Early Release of Top RU Cybercrook

March 15, 2022

Aleksei Burkov, a cybercriminal who long operated two of Russia’s most exclusive underground hacking forums, was arrested in 2015 by Israeli authorities. The Russian government fought Burkov’s extradition to the U.S. for four years — even arresting and jailing an Israeli woman to force a prisoner swap. That effort failed: Burkov was sent to America, pleaded guilty, and was sentenced to nine years in prison. But a little more than a year later, he was quietly released and deported back to Russia. Now some Republican lawmakers are asking why a Russian hacker once described as “an asset of supreme importance” was allowed to shorten his stay.

WeLeakInfo Leaked Customer Payment Info

March 15, 2021

A little over a year ago, the FBI and law enforcement partners overseas seized WeLeakInfo[.]com, a wildly popular service that sold access to more than 12 billion usernames and passwords stolen from thousands of hacked websites. In an ironic turn of events, a lapsed domain registration tied to WeLeakInfo let someone plunder and publish account data for 23,000 people who paid to access the service with a credit card.

Why Were the Russians So Set Against This Hacker Being Extradited?

November 18, 2019

The Russian government has for the past four years been fighting to keep 29-year-old alleged cybercriminal Alexei Burkov from being extradited by Israel to the United States. When Israeli authorities turned down requests to send him back to Russia — supposedly to face separate hacking charges there — the Russians then imprisoned an Israeli woman for seven years on trumped-up drug charges in a bid to trade prisoners. That effort failed as well, and Burkov had his first appearance in a U.S. court last week. What follows are some clues that might explain why the Russians are so eager to reclaim this young man.

A man arrested in Thailand this week on charges of stealing millions from online bank accounts fits the profile of a miscreant nicknamed “bx1,” a hacker fingered by Microsoft as a major operator of botnets powered by the ZeuS banking trojan.
