The FBI’s takedown of the LockBit ransomware group last week came as LockBit was preparing to release sensitive data stolen from government computer systems in Fulton County, Ga. But LockBit is now regrouping, and the gang says it will publish the stolen Fulton County data on March 2 unless paid a ransom. LockBit claims the cache includes documents tied to the county’s ongoing criminal prosecution of former President Trump, but court watchers say teaser documents published by the crime gang suggest a total leak of the Fulton County data could put lives at risk and jeopardize a number of other criminal trials.

In early February, Fulton County leaders acknowledged they were responding to an intrusion that caused disruptions for its phone, email and billing systems, as well as a range of county services, including court systems.
On Feb. 13, the LockBit ransomware group posted on its victim shaming blog a new entry for Fulton County, featuring a countdown timer saying the group would publish the data on Feb. 16 unless county leaders agreed to negotiate a ransom.
“We will demonstrate how local structures negligently handled information protection,” LockBit warned. “We will reveal lists of individuals responsible for confidentiality. Documents marked as confidential will be made publicly available. We will show documents related to access to the state citizens’ personal data. We aim to give maximum publicity to this situation; the documents will be of interest to many. Conscientious residents will bring order.”
Yet on Feb. 16, the entry for Fulton County was removed from LockBit’s site without explanation. This usually only happens after the victim in question agrees to pay a ransom demand and/or enters into negotiations with their extortionists.
However, Fulton County Commission Chairman Robb Pitts said the board decided it “could not in good conscience use Fulton County taxpayer funds to make a payment.”
“We did not pay nor did anyone pay on our behalf,” Pitts said at an incident briefing on Feb. 20.
Just hours before that press conference, LockBit’s various websites were seized by the FBI and the U.K.’s National Crime Agency (NCA), which replaced the ransomware group’s homepage with a seizure notice and used the existing design of LockBit’s victim shaming blog to publish press releases about the law enforcement action.
The feds used the existing design on LockBit’s victim shaming website to feature press releases and free decryption tools.
Dubbed “Operation Cronos,” the effort involved the seizure of nearly three-dozen servers; the arrest of two alleged LockBit members; the release of a free LockBit decryption tool; and the freezing of more than 200 cryptocurrency accounts thought to be tied to the gang’s activities. The government says LockBit has claimed more than 2,000 victims worldwide and extorted over $120 million in payments.
In a lengthy, rambling letter published on Feb. 24 and addressed to the FBI, the ransomware group’s leader LockBitSupp announced that their victim shaming websites were once again operational on the dark web, with fresh countdown timers for Fulton County and a half-dozen other recent victims.
“The FBI decided to hack now for one reason only, because they didn’t want to leak information fultoncountyga.gov,” LockBitSupp wrote. “The stolen documents contain a lot of interesting things and Donald Trump’s court cases that could affect the upcoming US election.”

LockBit has already released roughly two dozen files allegedly stolen from Fulton County government systems, although none of them involve Mr. Trump’s criminal trial. But the documents do appear to include court records that are sealed and shielded from public viewing.
George Chidi writes The Atlanta Objective, a Substack publication on crime in Georgia’s capital city. Chidi says the leaked data so far includes a sealed record related to a child abuse case, and a sealed motion in the murder trial of Juwuan Gaston demanding the state turn over confidential informant identities.
Chidi cites reports from a Fulton County employee who said the confidential material includes the identities of jurors serving on the trial of the rapper Jeffery “Young Thug” Williams, who is charged along with five other defendants in a racketeering and gang conspiracy.
“The screenshots suggest that hackers will be able to give any attorney defending a criminal case in the county a starting place to argue that evidence has been tainted or witnesses intimidated, and that the release of confidential information has compromised cases,” Chidi wrote. “Judge Ural Glanville has, I am told by staff, been working feverishly behind the scenes over the last two weeks to manage the unfolding disaster.”
LockBitSupp also denied assertions made by the U.K.’s NCA that LockBit did not delete stolen data as promised when victims agreed to pay a ransom. The accusation is an explosive one because nobody will pay a ransom if they don’t believe the ransomware group will hold up its end of the bargain.
The ransomware group leader also confirmed information first reported here last week, that federal investigators managed to hack LockBit by exploiting a known vulnerability in PHP, a scripting language that is widely used in Web development.
“Due to my personal negligence and irresponsibility I relaxed and did not update PHP in time,” LockBitSupp wrote. “As a result of which access was gained to the two main servers where this version of PHP was installed.”
LockBitSupp’s FBI letter said the group kept copies of its stolen victim data on servers that did not use PHP, and that consequently it was able to retain copies of files stolen from victims. The letter also listed links to multiple new instances of LockBit dark net websites, including the leak page listing Fulton County’s new countdown timer.
LockBit’s new data leak site promises to release stolen Fulton County data on March 2, 2024, unless paid a ransom demand.
“Even after the FBI hack, the stolen data will be published on the blog, there is no chance of destroying the stolen data without payment,” LockBitSupp wrote. “All FBI actions are aimed at destroying the reputation of my affiliate program, my demoralization, they want me to leave and quit my job, they want to scare me because they can not find and eliminate me, I can not be stopped, you can not even hope, as long as I am alive I will continue to do pentest with postpaid.”
In January 2024, LockBitSupp told XSS forum members he was disappointed the FBI hadn’t offered a reward for his doxing and/or arrest, and that in response he was placing a bounty on his own head — offering $10 million to anyone who could discover his real name.
After the NCA and FBI seized LockBit’s site, the group’s homepage was retrofitted with a blog entry titled, “Who is LockBitSupp? The $10M question.” The teaser made use of LockBit’s own countdown timer, and suggested the real identity of LockBitSupp would soon be revealed.
However, after the countdown timer expired the page was replaced with a taunting message from the feds, but it included no new information about LockBitSupp’s identity.
On Feb. 21, the U.S. Department of State announced rewards totaling up to $15 million for information leading to the arrest and/or conviction of anyone participating in LockBit ransomware attacks. The State Department said $10 million of that is for information on LockBit’s leaders, and up to $5 million is offered for information on affiliates.
In an interview with the malware-focused Twitter/X account Vx-Underground, LockBit staff asserted that authorities had arrested a couple of small-time players in their operation, and that investigators still do not know the real-life identities of the core LockBit members, or that of their leader.
“They assert the FBI / NCA UK / EUROPOL do not know their information,” Vx-Underground wrote. “They state they are willing to double the bounty of $10,000,000. They state they will place a $20,000,000 bounty of their own head if anyone can dox them.”
In the weeks leading up to the FBI/NCA takedown, LockBitSupp became embroiled in a number of high-profile personal and business disputes on the Russian cybercrime forums.
Earlier this year, someone used LockBit ransomware to infect the networks of AN-Security, a venerated 30-year-old security and technology company based in St. Petersburg, Russia. This violated the golden rule for cybercriminals based in Russia and former soviet nations that make up the Commonwealth of Independent States, which is that attacking your own citizens in those countries is the surest way to get arrested and prosecuted by local authorities.
LockBitSupp later claimed the attacker had used a publicly leaked, older version of LockBit to compromise systems at AN-Security, and said the attack was an attempt to smear their reputation by a rival ransomware group known as “Clop.” But the incident no doubt prompted closer inspection of LockBitSupp’s activities by Russian authorities.
Then in early February, the administrator of the Russian-language cybercrime forum XSS said LockBitSupp had threatened to have him killed after the ransomware group leader was banned by the community. LockBitSupp was excommunicated from XSS after he refused to pay an arbitration amount ordered by the forum administrator. That dispute related to a complaint from another forum member who said LockBitSupp recently stiffed him on his promised share of an unusually large ransomware payout.

KrebsOnSecurity sought comment from LockBitSupp at the ToX instant messenger ID listed in his letter to the FBI. LockBitSupp declined to elaborate on the unreleased documents from Fulton County, saying the files will be available for everyone to see in a few days.
LockBitSupp said his team was still negotiating with Fulton County when the FBI seized their servers, which is why the county has been granted a time extension. He also denied threatening to kill the XSS administrator.
“I have not threatened to kill the XSS administrator, he is blatantly lying, this is to cause self-pity and damage my reputation,” LockBitSupp told KrebsOnSecurity. “It is not necessary to kill him to punish him, there are more humane methods and he knows what they are.”
Asked why he was so certain the FBI doesn’t know his real-life identity, LockBitSupp was more precise.
“I’m not sure the FBI doesn’t know who I am,” he said. “I just believe they will never find me.”
It seems unlikely that the FBI’s seizure of LockBit’s infrastructure was somehow an effort to stave off the disclosure of Fulton County’s data, as LockBitSupp maintains. For one thing, Europol said the takedown was the result of a months-long infiltration of the ransomware group.
Also, in reporting on the attack’s disruption to the office of Fulton County District Attorney Fani Willis on Feb. 14, CNN reported that by then the intrusion by LockBit had persisted for nearly two and a half weeks.
Finally, if the NCA and FBI really believed that LockBit never deleted victim data, they had to assume LockBit would still have at least one copy of all their stolen data hidden somewhere safe.
Fulton County is still trying to recover systems and restore services affected by the ransomware attack. “Fulton County continues to make substantial progress in restoring its systems following the recent ransomware incident resulting in service outages,” reads the latest statement from the county on Feb. 22. “Since the start of this incident, our team has been working tirelessly to bring services back up.”
Update, Feb. 29, 3:22 p.m. ET: Just hours after this story ran, LockBit changed its countdown timer for Fulton County saying they had until the morning of Feb. 29 (today) to pay a ransonm demand. When the official deadline neared today, Fulton County’s listing was removed from LockBit’s victim shaming website. Asked about the removal of the listing, LockBit’s leader “LockBitSupp” told KrebsOnSecurity that Fulton County paid a ransom demand. County officials have scheduled a press conference on the ransomware attack at 4:15 p.m. ET today.
The cybercrime economy is one of the runaway success stories of the 21st century — at least, for those who participate in it. Estimates claim it could be worth over $1 trillion annually, more than the GDP of many countries. Part of that success is due to its ability to evolve and shift as the threat landscape changes. Trend Micro has been profiling the underground cybercrime community for many years. Over the past five years, we’ve seen a major shift to new platforms, communications channels, products and services, as trust on the dark web erodes and new market demands emerge.
We also expect the current pandemic to create yet another evolution, as cyber-criminals look to take advantage of new ways of working and systemic vulnerabilities.
Shifts in the underground
Our latest report, Shifts in the Cybercriminal Underground Markets, charts the fascinating progress of cybercrime over the past five years, through detailed analysis of forums, marketplaces and dark web sites around the world. It notes that in many product areas, the cost of items has dropped as they become commoditised: so where in 2015 you expected to pay $1000 per months for crypting services, today they may be as little as $20.
In other areas, such as IoT botnets, cyber-propaganda and stolen gaming account credentials, prices are high as new products spark surging demand. Fortnite logins can sell for around $1,000 on average, for example.
The good news is that law enforcement action appears to be working. Trend Micro has long partnered with Interpol, Europol, national crime agencies and local police to provide assistance in investigations. So it’s good to see that these efforts are having an impact. Many dark web forums and marketplaces have been infiltrated and taken down over the past five years, and our researchers note that current users complain of DDoS-ing and log-in issues.
Cybercriminals have been forced to take extreme measures as trust erodes among the community, for example, by using gaming communications service Discord to arrange trades, and e-commerce platform Shoppy.gg to sell items. A new site called DarkNet Trust was even created to tackle this specific challenge: it aims to verify cybercrime vendors’ reputations by analysing their usernames and PGP fingerprints.
What does the future hold?
However, things rarely stay still on the cybercrime underground. Going forward, we expect to see a range of new tools and techniques flood dark web stores and forums. AI will be at the centre of these efforts. Just as it’s being used by Trend Micro and other companies to root out fraud, sophisticated malware and phishing, it could be deployed in bots designed to predict roll patterns on gambling sites. It could also be used in deepfake services developed to help buyers bypass photo ID systems, or launch sextortion campaigns against individuals.
Some emerging trends are less hi-tech but no less damaging. Log-ins for wearable devices could be stolen and used to request replacements under warranty, defrauding the customer and costing the manufacturers dear. In fact, access to devices, systems and accounts is so common today that we’re already seeing it spun out in “as-a-service” cybercrime offerings. Prices for access to Fortune 500 companies can hit as much as $10,000.
Post-pandemic threats
Then there’s COVID-19. We’re already seeing fraudsters targeted government stimulus money with fake applications, sometimes using phished information from legitimate businesses. And healthcare organisations are being targeted with ransomware as they battle to save lives.
Even as the pandemic recedes, remote working practices are likely to stay in many organisations. What does this mean for cybercrime? It means more targeting of VPN vulnerabilities with malware and DDoS services. And it means more opportunities to compromise corporate networks via connected home devices. Think of it like a kind of Reverse BYOD scenario – instead of bringing devices into work to connect, the corporate network is now merged with home networks.
Tackling such challenges will demand a multi-layered strategy predicated around that familiar trio: people, process and technology. It will require more training, better security for home workers, improved patch management and password security, and much more besides. But most of all it will demand continued insight into global cybercriminals and the platforms they inhabit, to anticipate where the next threats are coming from.
Fortunately, this is where Trend Micro’s expert team of researchers come in. We won’t let them out of our sight.
