NEWARK, N.J. – A dual Russian and Israeli national was extradited to the United States on charges that he was a developer of the LockBit ransomware group, United States Attorney John Giordano announced.

In August, Rostislav Panev, 51, was arrested in Israel pursuant to a U.S. provisional arrest request.  Today, Panev was extradited to the United States and had an initial appearance before U.S. Magistrate Judge André M. Espinosa where Panev was detained pending trial.

“Rostislav Panev’s extradition to the District of New Jersey makes it clear: if you are a member of the LockBit ransomware conspiracy, the United States will find you and bring you to justice,” said United States Attorney John Giordano. “Even as the means and methods of cybercriminals become more sophisticated, my Office and our FBI, Criminal Division, and international law enforcement partners are more committed than ever to prosecuting these criminals.”

“No one is safe from ransomware attacks, from individuals to institutions. Along with our international partners, the FBI continues to leave no stone unturned when it comes to following LockBit’s trail of destruction. We will continue to work tirelessly to prevent actors, such as Panev, from hacking their way to financial gain,” said Acting Special Agent in Charge of the FBI Newark Division Terence G. Reilly.

According to the superseding complaint, documents filed in this and related cases, and statements made in court, Panev acted as a developer of the LockBit ransomware group from its inception in or around 2019 through at least February 2024. During that time, Panev and his LockBit coconspirators grew LockBit into what was, at times, the most active and destructive ransomware group in the world. The LockBit group attacked more than 2,500 victims in at least 120 countries around the world, including 1,800 in the United States. Their victims ranged from individuals and small businesses to multinational corporations, including hospitals, schools, nonprofit organizations, critical infrastructure, and government and law-enforcement agencies. LockBit’s members extracted at least $500 million in ransom payments from their victims and caused billions of dollars in other losses, including lost revenue and costs from incident response and recovery.

LockBit’s members were comprised of “developers,” like Panev, who designed the LockBit malware code and maintained the infrastructure on which LockBit operated. LockBit’s other members, called “affiliates,” carried out LockBit attacks and extorted ransom payments from LockBit victims. LockBit’s developers and affiliates would then split the ransom payments which were extorted from victims.

As alleged in the superseding complaint, at the time of Panev’s arrest in Israel in August, law enforcement discovered on Panev’s computer administrator credentials for an online repository that was hosted on the dark web and stored source code for multiple versions of the LockBit builder, which allowed LockBit’s affiliates to generate custom builds of the LockBit ransomware malware for particular victims. On that repository, law enforcement also discovered source code for LockBit’s StealBit tool, which helped LockBit affiliates exfiltrate data stolen through LockBit attacks. Law enforcement also discovered access credentials for the LockBit control panel, an online dashboard maintained by LockBit developers for LockBit’s affiliates and hosted by those developers on the dark web.

The superseding complaint also alleges that Panev exchanged direct messages through a cybercriminal forum with LockBit’s primary administrator, who, in an indictment unsealed in the District of New Jersey in May, the United States alleged to be Dimitry Yuryevich Khoroshev (Дмитрий Юрьевич Хорошев), also known as LockBitSupp, LockBit, and putinkrab. In those messages, Panev and the LockBit primary administrator discussed work that needed to be done on the LockBit builder and control panel.

Court documents further indicate that, between June 2022 and February 2024, the primary LockBit administrator made a series of transfers of cryptocurrency, laundered through one or more illicit cryptocurrency mixing services, of approximately $10,000 per month to a cryptocurrency wallet owned by Panev. Those transfers amounted to over $230,000 during that period.

In interviews with Israeli authorities following his arrest in August, Panev admitted to having performed coding, development, and consulting work for the LockBit group and to having received regular payments in cryptocurrency for that work, consistent with the transfers identified by U.S. authorities. Among the work that Panev admitted to having completed for the LockBit group was the development of code to disable antivirus software; to deploy malware to multiple computers connected to a victim network; and to print the LockBit ransom note to all printers connected to a victim network. Panev also admitted to having written and maintained LockBit malware code and to having provided technical guidance to the LockBit group.

The LockBit Investigation

The superseding complaint against, and apprehension of, Panev follows a disruption of LockBit ransomware in February 2024 by the U.K. National Crime Agency (NCA)’s Cyber Division, which worked in cooperation with the Justice Department, FBI, and other international law enforcement partners. As previously announced by the Department, authorities disrupted LockBit by seizing numerous public-facing websites used by LockBit to connect to the organization’s infrastructure and by seizing control of servers used by LockBit administrators, thereby disrupting the ability of LockBit actors to attack and encrypt networks and extort victims by threatening to publish stolen data. That disruption succeeded in greatly diminishing LockBit’s reputation and its ability to attack further victims, as alleged by documents filed in this case.

The superseding complaint against Panev also follows charges brought in the District of New Jersey against other LockBit members, including its alleged primary creator, developer, and administrator, Dmitry Yuryevich Khoroshev. An indictment against Khoroshev unsealed in May alleges that Khoroshev began developing LockBit as early as September 2019, continued acting as the group’s administrator through 2024, a role in which Khoroshev recruited new affiliate members, spoke for the group publicly under the alias “LockBitSupp,” and developed and maintained the infrastructure used by affiliates to deploy LockBit attacks. Khoroshev is currently the subject of a reward of up to $10 million through the U.S. Department of State’s Transnational Organized Crime (TOC) Rewards Program, with information accepted through the FBI tip website at www.tips.fbi.gov/.

A total of seven LockBit members have now been charged in the District of New Jersey. Beyond Panev and Khoroshev, other previously charged LockBit defendants include:

• In July, two LockBit affiliate members, Mikhail Vasiliev, also known as Ghostrider, Free, Digitalocean90, Digitalocean99, Digitalwaters99, and Newwave110, and Ruslan Astamirov, also known as BETTERPAY, offtitan, and Eastfarmer, pleaded guilty in the District of New Jersey for their participation in the LockBit ransomware group and admitted deploying multiple LockBit attacks against U.S. and foreign victims. Vasiliev and Astamirov are presently in custody awaiting sentencing.
• In February 2024, in parallel with the disruption operation described above, an indictment was unsealed in the District of New Jersey charging Russian nationals Artur Sungatov and Ivan Kondratyev, also known as Bassterlord, with deploying LockBit against numerous victims throughout the United States, including businesses nationwide in the manufacturing and other industries, as well as victims around the world in the semiconductor and other industries. Sungatov and Kondratyev remain at large.
• In May 2023, two indictments were unsealed in Washington, D.C., and the District of New Jersey charging Mikhail Matveev, also known as Wazawaka, m1x, Boriselcin, and Uhodiransomwar, with using different ransomware variants, including LockBit, to attack numerous victims throughout the United States, including the Washington, D.C., Metropolitan Police Department. Matveev remains at large and is currently the subject of a reward of up to $10 million through the U.S. Department of State’s TOC Rewards Program, with information accepted through the FBI tip website at www.tips.fbi.gov/.

The U.S. Department of State’s Transnational Organized Crime (TOC) Rewards Program is offering rewards of:

Khoroshev, Matveev, Sungatov, and Kondratyev have also been designated for sanctions by the Department of the Treasury’s Office of Foreign Assets Control for their roles in launching cyberattacks.

Victim Assistance

LockBit victims are encouraged to contact the FBI and submit information at www.ic3.gov. As announced by the Department in February, law enforcement, through its disruption efforts, has developed decryption capabilities that may enable hundreds of victims around the world to restore systems encrypted using the LockBit ransomware variant. Submitting information at the IC3 site will enable law enforcement to determine whether affected systems can be successfully decrypted.

LockBit victims are also encouraged to visit www.justice.gov/usao-nj/lockbit for case updates and information regarding their rights under U.S. law, including the right to submit victim impact statements and request restitution, in the criminal litigation against Panev, Astamirov, and Vasiliev.

The FBI Newark Field Office, under the supervision of Acting Special Agent in Charge Terence G. Reilly, is investigating the LockBit ransomware variant. Israel’s Office of the State Attorney, Department of International Affairs, and Israel National Police; France’s Gendarmerie Nationale Cyberspace Command, Paris Prosecution Office — Cyber Division, and judicial authorities at the Tribunal Judiciare of Paris; Europol; Eurojust; the United Kingdom’s National Crime Agency; Germany’s Landeskriminalamt Schleswig-Holstein, Bundeskriminalamt, and the Central Cybercrime Department North Rhine-Westphalia; Switzerland’s Federal Office of Justice, Public Prosecutor’s Office of the Canton of Zurich, and Zurich Cantonal Police; Spain’s Policia Nacional and Guardia Civil; authorities in Japan; Australian Federal Police; Sweden’s Polismyndighetens; Canada’s Royal Canadian Mounted Police; Politie Dienst Regionale Recherche Oost-Brabant of the Netherlands; and Finland’s National Bureau of Investigation have provided significant assistance and coordination in these matters and in the LockBit investigation generally.

Assistant U.S. Attorneys Andrew M. Trombly, David E. Malagold, and Vinay Limbachia for the District of New Jersey and Trial Attorneys Debra Ireland and Jorge Gonzalez of the Criminal Division’s Computer Crime and Intellectual Property Section (CCIPS) are prosecuting the charges against Panev and the other previously charged LockBit defendants in the District of New Jersey.

The Justice Department’s former Cybercrime Liaison Prosecutor to Eurojust, Office of International Affairs, and National Security Division also provided significant assistance.

Additional details on protecting networks against LockBit ransomware are available at StopRansomware.gov. These include Cybersecurity and Infrastructure Security Agency Advisories AA23-325A, AA23-165A, and AA23-075A. 

The charges and allegations contained in the superseding complaint and above-named Indictments are merely accusations, and the defendants are presumed innocent unless and until proven guilty.
