Feds Target $100M ‘GozNym’ Cybercrime Network

Law enforcement agencies in the United States and Europe today unsealed charges against 11 alleged members of the GozNym malware network, an international cybercriminal syndicate suspected of stealing $100 million from more than 41,000 victims with the help of a stealthy banking trojan by the same name.

The indictments unsealed in a Pennsylvania court this week stem from a slew of cyber heists carried out between October 2015 and December 2016. They’re also related to the 2016 arrest of Krasimir Nikolov, a 47-year-old Bulgarian man who was extradited to the United States to face charges for allegedly cashing out bank accounts that were compromised by the GozNym malware.

Prosecutors say Nikolov, a.k.a. “pablopicasso,” “salvadordali,” and “karlo,” was key player in the GozNym crime group who used stolen online banking credentials captured by GozNym malware to access victims’ online bank accounts and attempt to steal their money through electronic funds transfers into bank accounts controlled by fellow conspirators.

According to the indictment, the GozNym network exemplified the concept of ‘cybercrime as a service,’ in that the defendants advertised their specialized technical skills and services on underground, Russian-language, online criminal forums. The malware was dubbed GozNym because it combines the stealth of a previous malware strain called Nymaim with the capabilities of the powerful Gozi banking trojan.

The feds say the ringleader of the group was Alexander Konovolov, 35, of Tbilisi, Georgia, who controlled more than 41,000 victim computers infected with GozNym and recruited various other members of the cybercrime team.

Vladimir Gorin, a.k.a “Voland,”  “mrv,” and “riddler,” of Orenburg, Russia allegedly was a malware developer who oversaw the creation, development, management, and leasing of GozNym.

The indictment alleges 32-year-old Eduard Malancini, a.k.a. “JekaProf” and “procryptgroup” from Moldova, specialized in “crypting” or obfuscating the GozNym malware to evade detection by antivirus software.

Four other men named in the indictment were accused of recruiting and managing “money mules,” willing or unwitting people who can be used to receive stolen funds on behalf of the criminal syndicate. One of those alleged mule managers — Farkhad Rauf Ogly Manokhim (a.k.a. “frusa”) of Volograd, Russia was arrested in 2017 in Sri Lanka on an international warrant from the United States, but escaped and fled back to Russia while on bail awaiting extradition.

Also charged was 28-year-old Muscovite Konstantin Volchkov, a.k.a. “elvi,”  who allegedly provided the spamming service used to disseminate malicious links that tried to foist GozNym on recipients who clicked.

The malicious links referenced in those spam emails were served via the Avalanche bulletproof hosting service, a distributed, cloud-hosting network that for seven years was rented out to hundreds of fraudsters for use in launching malware and phishing attacks. Avalanche was dismantled in Dec. 2016 by a similar international law enforcement action.

The alleged administrator of the Avalanche bulletproof network — 36-year-old Gennady Kapkanov from Poltova, Ukraine — has eluded justice in prior scrapes with the law: During the Avalanche takedown in Dec. 2016, Kapkanov fired an assault rifle at Ukrainian police who were trying to raid his apartment.

Bot Roundup: Avalanche, Kronos, NanoCore

It’s been a busy few weeks in cybercrime news, justifying updates to a couple of cases we’ve been following closely at KrebsOnSecurity. In Ukraine, the alleged ringleader of the Avalanche malware spam botnet was arrested after eluding authorities in the wake of a global cybercrime crackdown there in 2016. Separately, a case that was hailed as a test of whether programmers can be held accountable for how customers use their product turned out poorly for 27-year-old programmer Taylor Huddleston, who was sentenced to almost three years in prison for making and marketing a complex spyware program.

First, the Ukrainian case. On Nov. 30, 2016, authorities across Europe coordinated the arrest of five individuals thought to be tied to the Avalanche crime gang, in an operation that the FBI and its partners abroad described as an unprecedented global law enforcement response to cybercrime. Hundreds of malicious web servers and hundreds of thousands of domains were blocked in the coordinated action.

The alleged leader of the Avalanche gang — 33-year-old Russian Gennady Kapkanov — did not go quietly at the time. Kapkanov allegedly shot at officers with a Kalashnikov assault rifle through the front door as they prepared to raid his home, and then attempted to escape off of his 4th floor apartment balcony. He was later released, after police allegedly failed to file proper arrest records for him.

But on Monday Agence France-Presse (AFP) reported that Ukrainian authorities had once again collared Kapkanov, who was allegedly living under a phony passport in Poltav, a city in central Ukraine. No word yet on whether Kapkanov has been charged, which was supposed to happen Monday.

HOW WELL DO YOU REALLY WANT TO KNOW YOUR CUSTOMERS?

Lawyers for Taylor Huddleston, a 27-year-old programmer from Hot Springs, Ark., originally asked a federal court to believe that the software he sold on the sprawling hacker marketplace Hackforums — a “remote administration tool” or “RAT” designed to let someone remotely administer one or many computers remotely — was just a benign tool.

The bad things done with Mr. Huddleston’s tools, the defendant argued, were not Mr. Huddleston’s doing. Furthermore, no one had accused Mr. Huddleston of even using his own software.

The Daily Beast first wrote about Huddleston’s case in 2017, and at the time suggested his prosecution raised questions of whether a programmer could be held criminally responsible for the actions of his users. My response to that piece was “Dual-Use Software Criminal Case Not So Novel.

The court was swayed by evidence that yes, Mr. Huddleston could be held criminally responsible for those actions. It sentenced him to 33 months in prison after the defendant acknowledged that he knew his RAT — a Remote Access Trojan dubbed “NanoCore RAT” — was being used to spy on webcams and steal passwords from systems running the software.

Of course Huddleston knew: He didn’t market his wares on some Craigslist software marketplace ad, or via video promos on his local cable channel: He marketed the NanoCore RAT and another software licensing program called Net Seal exclusively on Hackforums[dot]net.

This sprawling, English language forum has a deep bench of technical forum discussions about using RATs and other tools to surreptitiously record passwords and videos of “slaves,” the derisive term for systems secretly infected with these RATs.

Huddleston knew what many of his customers were doing because many NanoCore users also used Huddleston’s Net Seal program to keep their own RATs and other custom hacking tools from being disassembled or “cracked” and posted online for free. In short: He knew what programs his customers were using Net Seal on, and he knew what those customers had done or intended to do with tools like NanoCore.

The sentencing suggests that where you choose to sell something online says a lot about what you think of your own product and who’s likely buying it.

Daily Beast author Kevin Poulsen noted in a July 2017 story that Huddleston changed his tune and pleaded guilty. The story pointed to an accompanying plea in which Huddleston stipulated that he “knowingly and intentionally aided and abetted thousands of unlawful computer intrusions” in selling the program to hackers and that he “acted with the purpose of furthering these unauthorized computer intrusions and causing them to occur.” Continue reading →

‘Avalanche’ Crime Ring Leader Eludes Justice

The accused ringleader of a cyber fraud gang that allegedly rented out access to a criminal cloud hosting service known as “Avalanche” is now a fugitive from justice following a bizarre series of events in which he shot at Ukrainian police, was arrested on cybercrime charges and then released from custody.

On Nov. 30, authorities across Europe coordinated the arrest of five individuals thought to be tied to the Avalanche crime gang, in an operation that the FBI and its partners abroad described as an unprecedented global law enforcement response to cybercrime.

According to Ukrainian news outlets, the alleged leader of the gang — 33-year-old Russian Gennady Kapkanov — did not go quietly. Kapkanov allegedly shot at officers with a Kalashnikov assault rifle through the front door as they prepared to raid his home, and then attempted to escape off of his 4th floor apartment balcony.

Ukrainian police arrested Kapkanov and booked him on cybercrime charges. But a judge in the city of Poltava, Ukraine later ordered Kapkanov released, saying the prosecution had failed to file the proper charges (including charges of shooting at police officers), charges which could have allowed authorities to hold him much longer. Ukrainian media reports that police have since lost track of Kapkanov.

Ukraine’s Prosecutor General Yuri Lutsenko is now calling for the ouster of the prosecutor in charge of the case. Meanwhile, the Ukranian authorities are now asking the public for help in re-arresting Kapkanov.
