More details have emerged on individuals arrested in conjunction with Phobos ransomware and the seizure of 8Base sites. From the U.S. Attorney’s Office, District of Maryland:
The Justice Department today unsealed criminal charges against Roman Berezhnoy, 33, and Egor Nikolaevich Glebov, 39, both Russian nationals, who allegedly operated a cybercrime group using the Phobos ransomware that victimized more than 1,000 public and private entities in the United States and around the world and received over $16 million in ransom payments. Berezhnoy and Glebov were arrested yesterday as part of a coordinated international disruption of their organization, which includes additional arrests and the technical disruption of the group’s computer infrastructure.
From May 2019, through at least October 2024, Berezhnoy, Glebov, and others allegedly caused victims to suffer losses resulting from the loss of access to their data in addition to the financial losses associated with the ransomware payments. The victims included a children’s hospital, health care providers, and educational institutions.
According to court documents, Berezhnoy, Glebov, and others operated a ransomware affiliate organization, including under the names “8Base” and “Affiliate 2803,” among others, that victimized public and private entities through the deployment of Phobos ransomware.
As part of the scheme, Berezhnoy, Glebov, and others allegedly hacked into victim computer networks, copied and stole files and programs on the victims’ network, and encrypted the original versions of the stolen data with Phobos ransomware. The conspirators then allegedly extorted the victims for ransom payments in exchange for the decryption keys to regain access to the encrypted data by, among other things, leaving a ransom note on compromised victim computers and separately reaching out to victims to initiate ransom payment negotiations.
As alleged, the conspirators also threatened to expose victims’ stolen files to the public or to the victims’ clients, customers, or constituents if the ransoms were not paid. The conspirators are further alleged to have established and operated a darknet website where they repeated their extortionate threats and ultimately published the stolen data if a victim failed to pay the ransom.
After a successful Phobos ransomware attack, criminal affiliates paid fees to Phobos administrators for a decryption key to regain access to the encrypted files. Each deployment of Phobos ransomware was assigned a unique alphanumeric string in order to match it to the corresponding decryption key, and each affiliate was directed to pay the decryption key fee to a cryptocurrency wallet unique to that affiliate.
The charges unsealed today against Berezhnoy and Glebov follow the recent arrest and extradition of Evgenii Ptitsyn, a Russian national, on charges relating to his alleged administration of the Phobos ransomware variant.
In parallel with today’s arrests, Europol and German authorities have announced an international operation involving the FBI and other international law enforcement partners to disrupt over 100 servers associated with this criminal network.
Berezhnoy and Glebov are charged in an 11-count indictment with one count of wire fraud conspiracy, one count of wire fraud, one count of conspiracy to commit computer fraud and abuse, three counts of causing intentional damage to protected computers, three counts of extortion in relation to damage to a protected computer, one count of transmitting a threat to impair the confidentiality of stolen data, and one count of unauthorized access and obtaining information from a protected computer. If convicted, Berezhnoy and Glebov face a maximum penalty of 20 years in prison on each wire fraud-related count; 10 years in prison on each computer damage count; and five years in prison on each of the other counts. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.
Erek L. Barron, U.S. Attorney for the District of Maryland; Supervisory Official Antoinette T. Bacon of the Justice Department’s Criminal Division; and Special Agent in Charge William J. DelBagno of the FBI Baltimore Field Office, made the announcement.
The FBI Baltimore Field Office is investigating the case. The Justice Department extends its thanks to international judicial and law enforcement partners in the United Kingdom, Germany, Japan, Spain, Belgium, Poland, Czech Republic, France, Thailand, Finland, and Romania, as well as Europol and the U.S. Department of Defense Cyber Crime Center, for their cooperation and coordination with the Phobos ransomware investigation. The Justice Department’s National Security Division and Office of International Affairs also provided valuable assistance.
Assistant U.S. Attorney Thomas M. Sullivan for the District of Maryland and Senior Counsel Aarash A. Haghighat of the Criminal Division’s Computer Crime and Intellectual Property Section (CCIPS) are prosecuting the case. Former CCIPS Trial Attorney Riane Harper and former Assistant U.S. Attorneys Aaron S.J. Zelinsky and Jeffrey J. Izant for the District of Maryland provided substantial assistance.
