A Canadian man pleaded guilty to playing a central role in one of the most far-reaching cyberattacks of 2024 — the widespread compromise of more than 165 Snowflake customer environments, resulting in massive data theft for extortion, the Justice Department said Wednesday. 

Connor Moucka earned $495,000 by extorting his victims, offering stolen data for sale online, and in one case re-extorted a victim with stolen data of a government official and members of a then-former government official’s immediate family, authorities said.

Moucka and his alleged co-conspirators John Binns and Cameron Wagenius stole billions of sensitive records and received more than $2.5 million in extortion payments combined, according to prosecutors. Victims of the attack spree included AT&T, Ticketmaster, Advance Auto Parts and Santander.

“Hiding behind a screen is no shield from justice,” Brett Leatherman, assistant director of the FBI’s Cyber Division, said in a statement. “Moucka learned that when he was arrested just months after he began targeting U.S. companies, stealing sensitive information, and extorting victims for millions of dollars.”

Authorities arrested Moucka relatively quickly because he caused significant damage, said Allison Nixon, chief research officer at Unit 221B. 

“His gang went on a spree of maximizing harm, which directly correlated to maximizing the resources devoted to stopping it,” she said. 

“His behavior was bizarre throughout. Even while stealing data and extorting victims, he did many unnecessary things like threatening me because he thought I was working on his case. I was not working on his case before he threatened me,” Nixon added.

Moucka, who used several aliases online, including “Waifu,” “Judische,” “Catist” and “Ellyel8,” was arrested Oct. 30, 2024, in Kitchener, a city in the Canadian province of Ontario, at the behest of U.S. authorities. He was extradited to the United States in March 2025.

Moucka and his co-conspirators used stolen credentials to access the data storage platform’s customers’ accounts en masse. Records of more than 100 million people were exposed by the data theft campaign, including call and text history records, banking and other financial information, payroll records, government ID numbers and other personally identifiable data. 

Officials said victim companies bore more than $9.5 million in losses combined, not including losses attributable to their respective customers. 

Moucka’s threats and re-extortion tactics were calculated and predatory, and his actions did real harm to his victims, be they companies targeted for theft and extortion or the millions of everyday people who are their customers,” W. Mike Herrington, special agent in charge of the FBI Seattle field office, said in a statement.

Researchers said Moucka and his co-conspirators are all associated with The Com, a sprawling cybercriminal network of minors and young adults who engage in violence, extortion, sextortion and various forms of cybercrime.

“His legacy is one of failure. He extorted and then scammed his victims by not deleting the data, casting doubt on all future pay-or-leak extortion gangs,” Nixon said. 

“The pay-or-leak business model was popularized by him and his gang,” and his claims of data deletion were a lie, she added. “With copycat gangs, defenders grapple with the uncertainty of whether the threat actors are honest.”

Moucka pleaded guilty to computer fraud, wire fraud, aggravated identity theft and a related conspiracy. He is scheduled for sentencing Oct. 27 and faces up to 32 years in prison.

A 41-year-old Ghanaian national was sentenced to 85 months in prison for stealing more than $10 million from mostly older, lonely and vulnerable victims via romance scams, the Justice Department said Tuesday. 

Derrick Van Yeboah was a longtime and high-ranking member of a criminal organization primarily based in Ghana linked to more than $100 million stolen from romance scams and business email compromises, officials said. Van Yeboah served as a “sakawa boy,” impersonating fake romantic partners and directly interacting with victims online from February 2015 to October 2024.

“Romance scammers do not simply steal money — they weaponize trust,” Jay Clayton, U.S. attorney for the Southern District of New York, said in a statement. 

Van Yeboah was arrested in Ghana in June 2025, acting on a request from the Justice Department, and extradited to the United States two months later. He pleaded guilty to conspiracy to commit wire fraud and agreed to forfeit $10.15 million in fraudulent proceeds as part of a plea agreement in March.

Authorities said they identified at least 20 of Van Yeboah’s victims, noting that some were deceived into sending their money to the criminal organization, creating companies and using those entities to unwittingly launder funds from other victims. 

Victims include a woman from Delaware who either sent or laundered $1.9 million, a woman from Ohio who sent or laundered $2.3 million and another woman who sent or laundered about $1 million. Van Yeboah also tricked a North Carolina man to send $123,000, claiming he needed a loan to pay for his mother’s funeral expenses and to remove imaginary gold and diamonds from storage in Italy, according to court records.

Officials said Van Yeboah received a substantial amount of money from his criminal acts. He told pretrial services his assets include a house worth $1.5 million and jewelry worth $515,000. When he was arrested, Ghanaian police found him in possession of two vehicles stolen from the United States and Canada.

“Victims lost large portions of their life savings, money they had counted on for retirement. They were emotionally devastated to learn that the personas they had been talking to every day, personas who claimed to be in love with them, were in fact frauds,” Clayton wrote in a pre-sentencing letter to the court. 

Van Yeboah’s conduct was cruel, and he fully understood the financial and emotional harm he was causing to his victims, he added. 

“Van Yeboah’s conduct was far from an aberration. Van Yeboah engaged in the fraud scheme for nine years. It wasn’t isolated conduct; it wasn’t a blip,” Clayton wrote. “Indeed, it appears to be the only real job Van Yeboah has ever had. Day after day, for years, he targeted vulnerable victims, lied to them, and stole from them.”

An Armenian national who was extradited from Ukraine to the United States last year pleaded guilty to participating in a series of attacks in 2019 and 2020 involving Ryuk ransomware, the Justice Department said Thursday.

Karen Serobovich Vardanyan pleaded guilty to computer fraud and conspiracy to commit fraud and extortion. He agreed to pay nearly $1.2 million million in restitution and faces up to 15 years in jail.

The 34-year-old admitted to participating in cybercrime from November 2019 to April 2020 when he and his co-conspirators deployed Ryuk ransomware against three U.S.-based organizations while living in Ukraine and Russia.

Vardanyan’s victims include a Michigan-based company that paid a ransom of nearly $1.2 million in January 2020, a Watsonville, Oregon-based technology company that was attacked in December 2019 and a Texas-based school breached in February 2020.

Prosecutors previously accused Vardanyan and his co-conspirators — Ukrainian nationals Oleg Nikolayevich Lyulyava and Andrii Leonydovich Prykhodchenko, and Armenian national Levon Georgiyovych Avetisyan — of illegally accessing computer networks to deploy Ryuk ransomware on hundreds of compromised servers and workstations between March 2019 and September 2020.

Ryuk ransomware was prevalent in 2019 and 2020, infecting thousands of victims globally across the private sector, state and local municipalities, local school districts and critical infrastructure, including a wave of attacks on U.S. hospitals.

Victims of Ryuk ransomware attacks include Hollywood Presbyterian Medical Center, Universal Health Services, Electronic Warfare Associates, a North Carolina water utility and multiple U.S. newspapers.

Ryuk ransomware operators extorted victim companies by demanding ransom payments in Bitcoin in exchange for decryption keys. Justice Department officials said Vardanyan and his co-conspirators received about 1,160 bitcoins — valued at more than $15 million at the time — in ransom payments from victim companies.

Vardanyan, as part of his guilty plea, also acknowledged that his conviction will have immigration consequences resulting in removal from the United States after serving his sentence. 

The U.S. District Court for the District of Oregon has yet to schedule his sentencing.

A San Antonio man who sexually exploited children while leading 8884, an offshoot of the notorious violent extremist collective 764, was sentenced to 40 years in prison in federal court Wednesday, the Justice Department said. 

Alexis Aldair Chavez began associating with 764 as a child in 2022 when a co-conspirator introduced him to 7997, one of many 764 offshoots affiliated with the Com. The sprawling nihilistic network of thousands of people, typically between 11 and 25 years old, seek to foster social unrest by destroying civilized society through the corruption and exploitation of children and other vulnerable populations.

The 19-year-old, also known as “Zack” and “Zack8884,” attempted to coerce a girl to commit suicide and blackmailed another girl into self-mutiliation, animal torture and illicit content production in late 2023, according to court records. He later worked with multiple co-conspirators and blackmailed some of his victims to coerce other girls to degrade themselves on camera and produce child sexual abuse material (CSAM).

Chavez was arrested and has been detained without bail since October 2024. He pleaded guilty to multiple crimes involving the sexual exploitation of children in December 2025 and faced up to 60 years in prison for racketeering, distribution and possession of CSAM.

“Chavez’s crimes reveal the ruthless exploitation and manipulation at the core of nihilistic violent extremist groups,” John A. Eisenberg, assistant attorney general for national security, said in a statement. 

“These organizations target children as part of their broader mission to spread terror. These groups ultimately seek nothing less than the destruction of our society,” he added. “The National Security Division will use every resource at its disposal to identify and prosecute 764-linked criminality and to protect the most innocent among us from these predators.”

The indictment filed against Chavez in the U.S. District Court for the Western District of Texas details a series of horrifying crimes he committed with co-conspirators and some of his victims. 

Prosecutors said Chavez and a co-conspirator coerced a girl to cut her tongue, and torture and kill a cat on a live video call in late 2023. He and co-conspirators also, that same month, groomed and extorted several other girls to commit self harm and degrade themselves on camera.

Allison Nixon, chief research officer at Unit 221B, told CyberScoop the sentence is appropriate even if people understandably dislike imprisoning young people. 

“In this space, a certain personality profile is highly predictive of who will risk a prison sentence like this: an obsession with maximizing harm,” she said. 

“Reoffending after release is a huge problem. All major global hacking incidents from the Com are done by serial reoffenders — all obsessed with harmfulness, some graduated from the 764 sextortion space,” Nixon added.

Too many jurisdictions are naive in how they handle cases involving members or associates of the Com, allowing these criminals to go home to parents who won’t supervise them, she said.

Officials pressed on this in their reaction to Chavez’s sentencing as well. “Parents need to know what their children are doing online and must stay engaged, ask difficult questions, and not fall into the trap of believing their child is ‘just playing games’ or ‘just talking with their friends,’” Justin R. Simmons, U.S. attorney for the Western District of Texas, said in a statement. 

“There is darkness present within many people in this world that want nothing more than to see the United States and western civilization fail. There is no limit to the actions these individuals will take to accomplish that goal, including torturing and abusing children,” Simmons added.

Chavez, who was also ordered to pay $10,000 in restitution and serve lifetime supervised release, joins other 764 members already serving long sentences for similar crimes. Bradley Chance Cadenhed, who founded 764 as a 15-year-old in 2021, was arrested later that year and sentenced to 80 years in prison in 2023. 

When the FBI executed a search warrant at Chavez’s residence in July 2024, prosecutors said he came out the backdoor and threw his phone over a neighbor’s fence in an attempt to hide evidence.

Chavez’s sentencing follows a period of heightened law enforcement activity, which has netted arrests of multiple alleged 764 leaders and members. Some of the alleged 764 members arrested since 2025  include: Leonidas Varagiannis and Prasan Nepal, Baron Cain Martin, Tony Christopher Long, Erik Lee Madison, Zachary Sweeney and Aaron Corey. 

“True rehabilitation is the best outcome, but no one knows how,” Nixon said. 

“The total number of offenders who fit this harm-obsessed profile is vanishingly small. Giving them maximum sentences won’t overflow jails,” she added. 

Law enforcement and judges have to be realistic about what it takes to prevent the victimization of children, and handing down lifelong or lengthy prison sentences strikes the right balance between the rights of the offender and society, Nixon said.

FBI officials and agents who track these offenders and gather evidence on their crimes draw similar conclusions. 

“Nothing is more abhorrent than those who prey on children and other vulnerable members of our society and this defendant will pay a steep price for doing just that,” Coult Markovsky, acting assistant director of the FBI’s counterterrorism division, said in a statement.

“This sentencing demonstrates the FBI’s unwavering resolve to identify, hunt down, investigate, and prosecute criminals like Chavez who prey on children through violent online networks, including 764, and orchestrate horrific, unspeakable acts of exploitation and violence,” Daniel Faith, special agent in charge of the FBI San Antonio field office, said in a statement. 

“These predators use social media, messaging apps, gaming platforms, chat rooms, and video services to groom vulnerable children,” Faith added. “Staying engaged in your child’s online life, maintaining open communication, recognizing the warning signs, and reporting suspicious online activity to law enforcement are critical to stopping these offenders.”

A longtime former member of Conti, a ransomware group that attacked more than 1,000 organizations globally before it disbanded in 2022, pleaded guilty to participating in some of those attacks in federal court Wednesday, the Justice Department said.

Oleksii Oleksiyovych Lytvynenko, also known as Alexsey Alexseevich Litvinenko, admitted he joined the prolific cybercrime group in September 2021 and held data on 12 victims, including eight based in the United States. The 44-year-old told the court he developed malware that Conti used in some of its attacks, according to officials. 

“The defendant and his conspirators used the Conti ransomware to terrorize people and businesses in the United States and around the world, causing millions of dollars in damage,” A. Tysen Duva, assistant attorney general of the Justice Department’s criminal division, said in a statement.

Lytvynenko and his co-conspirators used the ransomware to attack more than 1,000 victims globally, ensnaring victims in 47 states, Washington, Puerto Rico and about 31 countries, according to the Justice Department. The FBI estimates Conti extorted more than $150 million in ransom payments from victims.

The Ukrainian national pleaded guilty to conspiracy to commit wire fraud and faces up to 20 years in prison upon sentencing, which is scheduled for Sept. 10. 

Lytvynenko was arrested in Ireland in July 2023, extradited to the United States in October 2025, and remains in federal custody in Tennessee where at least three of his victims are based. He left Ukraine in 2022 and obtained temporary protective status in Ireland, residing in Cork at the time of his arrest. 

Prosecutors said Lytvynenko and his co-conspirators extorted about $634,000 in Bitcoin from two victims in Tennessee, including an undisclosed government entity that resulted in the compromise of a sheriff’s department, local emergency medical services and a local police department. According to an indictment that was unsealed last fall, Lytvynenko and his co-conspirators also leaked data they stole from another Tennessee-based victim after it refused to pay a $3 million ransom demand.

Four of Lytvynenko’s alleged co-conspirators — Maksim Galochkin, Maksim Rudenskiy, Mikhail Mikhailovich Tsarev and Andrey Yuryevich Zhuykov — were indicted in 2023 in the same federal court for crimes related to their suspected involvement in Conti attacks from 2020 to 2022. 

Authorities said Lytvynenko engaged in cybercrime after Conti disbanded and its members splintered off into new groups, adding that he “was asleep but within arms’ reach of an open laptop running Cobalt Strike” at the time of his arrest.

At one point, Conti was among the most prolific ransomware groups globally, impacting hundreds of critical infrastructure providers, Costa Rica’s government in 2022, and ultimately leading the State Department to offer a $10 million reward for information related to Conti’s leaders. The group was notoriously resilient, bouncing back with new infrastructure and hitting new targets after a massive leak exposed chats between the group’s members in 2022.

Conti disbanded later that year, but members of the Cyrillic-language group rebranded under three subgroups: Zeon, Black Basta and Quantum, which quickly rebranded to Royal, before rebranding again to BlackSuit in 2024.

“Lytvynenko’s guilty plea is a significant step toward holding cyber criminals accountable for the damage they inflict on victims worldwide,” Brett Leatherman, assistant director of the FBI’s cyber division, said in a statement “Lytvynenko profited from fear and coercion, conspiring to use Conti ransomware to extort victims and steal their data.”

A Tennessee man accused of abusing and sexually exploiting children while actively participating in 764, a sprawling online nihilistic violent extremist collective affiliated with The Com, pleaded not guilty Thursday to a series of charges that could keep him locked up for 50 years.

Zachary Sweeney has allegedly victimized multiple children, on numerous occasions grooming and coercing minors to produce child sexual abuse material that he distributed and sometimes sold, the Justice Department said. One of the 30-year-old’s alleged victims later died of an overdose.

Sweeney has been the subject of multiple FBI investigations, which uncovered extensive crimes against children dating back to at least 2022, prosecutors said. His alleged involvement in 764 and, by extension, The Com, underscores the growing, multi-faceted threat of physical violence, cybercrime, extortion and the pursuit of criminal underground notoriety posed by thousands of members typically between 11 and 25 years old.

Victims of these crimes are often young, vulnerable and degraded or traumatized for years with life-altering impact.

“Violent extremists who victimize vulnerable children online are among the worst predators in our community and across the country,” Braden Boucek, U.S. attorney for the Middle District of Tennessee, said in a statement.

Members of 764 and related groups commit crimes in the United States and engage with other extremists globally to foment social unrest and destroy civilized society through the corruption and exploitation of vulnerable people, the Justice Department said.

Police arrested Sweeney Thursday and charged him with three counts of sexual exploitation and attempted sexual exploitation of a minor and three counts of receiving visual depictions of CSAM. Prosecutors said they intend to request Sweeney remain detained at his next court appearance June 3. 

Sweeney allegedly traveled to New York, Indiana, Missouri and Georgia to meet numerous victims in person. Officials received reports from some of his alleged victims and online platforms, triggering FBI interviews with some of his alleged victims as early as 2023. 

One of his alleged victims, who began interacting with Sweeney when she was a teenager, told investigators she degraded herself and participated in virtual self-harm group video calls with a group of people she described as friends of his in The Com. Sweeney alleged raped her and streamed the crime online. 

She died of an overdose in 2024, approximately ten days after FBI agents interviewed her. 

Sweeney allegedly drugged and raped other victims and shared videos of those acts online, according to court records.

The FBI searched Sweeney’s residence in St. Louis in September 2023, more than two months after Meta sent a pair of tips to the National Center for Missing and Exploited Children that linked him to Instagram chats containing CSAM.

Agents seized devices containing evidence of 99 possible CSAM images and videos, but encryption and passwords prevented authorities from conducting further examination, according to court records.

Sweeney moved to Tennessee in the summer of 2024 and allegedly continued to travel out of state to meet victims in person and coerce other victims to produce CSAM through at least the summer of 2025.

Authorities accuse Sweeney of boasting about his crimes and sharing blackmail material, sexual assault and CSAM depicting underage female victims.

Authorities have arrested multiple members of 764 during the past year, reflecting heightened law enforcement activity targeting the violent extremist collective and other offshoots affiliated with The Com.

Two alleged leaders of 764, Leonidas Varagiannis and Prasan Nepal, were arrested and charged for directing and distributing CSAM in April. Alexis Aldair Chavez, of San Antonio, pleaded guilty in December to multiple crimes involving the sexual exploitation of children while acting as an administrator and leader of 8884, a splinter group of 764.

“This operation puts every child predator on notice: the FBI will hunt you down and bring you to justice,” Terence Reilly, special agent in charge of the FBI Nashville Field Office, said in a statement. “Removing violent extremists from our streets protects our most innocent and vulnerable members of society.”

A federal judge sentenced a Latvian national to 102 months in prison for his involvement in a series of ransomware attacks for more than two years prior to his arrest in 2023, the Justice Department said Monday.

Deniss Zolotarjovs, a resident of Moscow at the time, helped an organization led by former leaders of the Conti ransomware group extort payments from more than 54 companies. 

The 35-year-old was mostly tasked with putting pressure on the crew’s victims. In one case, Zolotarjovs urged co-conspirators to leak or sell children’s health records stolen from a pediatric healthcare company and ultimately sent a collection of sensitive data to “hundreds of patients,” according to court records. 

The ransomware crew identified itself in ransom notes under multiple names during Zolotarjovs’ involvement, including Conti, Karakurt, Royal, TommyLeaks, SchoolBoys Ransomware, Akira and others. 

Zolotarjov and his co-conspirators extorted nearly $16 million in confirmed ransom payments from their victims. Officials estimate the group’s crimes resulted in hundreds of millions of dollars in losses, not including the psychological and future financial exposure confronting tens of thousands of people whose personal data was stolen.

“Deniss Zolotarjovs helped his ransomware gang profit from hacks of dozens of companies, and even on a government entity whose 911 system was forced offline,” A. Tysen Duva, assistant attorney general of the Justice Department’s Criminal Division, said in a statement. 

Officials said Zolotarjovs searched for points of leverage after researching victim companies and analyzing stolen data. Many of the victims impacted during his active participation between June 2021 and August 2023 were based in the United States.

Zolotarjov was arrested in the country of Georgia in December 2023 and extradited to the United States in August 2024. He pleaded guilty to money laundering and wire fraud in July 2025. 

“Cybercriminals might think they are invulnerable by hiding behind anonymizing tools and complex cryptocurrency patterns while they attack American victims from non-extradition countries,” Dominick S. Gerace II, U.S. attorney for the Southern District of Ohio, said in a statement. “But Zolotarjovs’s prosecution shows that federal law enforcement also has a global reach, and we will hold accountable bad actors like Zolotarjovs, who will now spend significant time in prison.”

The Russian ransomware crew was prolific and spread across multiple teams, relying on companies registered in Russia, Europe and the United States to conceal its operations. Authorities said the group included former Russian law enforcement officers whose connections allowed members to access Russian government databases to harass detractors and identify potential new recruits.

Conti was among the most prolific ransomware groups globally for a time, impacting hundreds of critical infrastructure providers, Costa Rica’s government in 2022, and ultimately leading the State Department to offer a $10 million reward for information related to Conti’s leaders. The group was notoriously resilient, bouncing back with new infrastructure and hitting new targets after a massive leak exposed chats between the group’s members in 2022.

Conti disbanded later that year, but members of the Cyrillic-language group rebranded under three subgroups: Zeon, Black Basta and Quantum, which quickly rebranded to Royal, before rebranding again to BlackSuit in 2024.
