“As part of his duties, the defendant was provided with details regarding the attack and information regarding the ransom demand and typically the victim’s applicable insurance coverage and negotiating strategy,” the factual proffer said.
Martino used BlackCat’s live chat system to negotiate ransom payments. Starting in April 2023, he “began communicating with BlackCat actors through the messaging platform Tox and in a separate ‘intermediary chat’ tab of the BlackCat panel,” which “was only accessible to the defendant and the BlackCat negotiators and affiliates,” the factual proffer said.
Martino used the intermediary chat tab to provide confidential information about clients.
“The purpose of these intermediary chat communications was to maximize the ransom payments paid by those victims to the BlackCat actors,” the court document said. “This information provided by the defendant without the victims’ knowledge included the victims’ insurance policy limits and internal negotiation positions. In exchange for providing confidential information, the defendant received a portion of the ransomware payments in digital currency.”
In May 2023, Martino obtained affiliate access to the BlackCat panel, and he shared that access with the co-conspirators. “After the defendant obtained affiliate access, the defendant, Co-conspirator 1, and Co-Conspirator 2 agreed to, and did use the BlackCat ransomware and platform to attack and extort victims and share the ransom proceeds amongst themselves and with the BlackCat admin,” the factual proffer said.
DigitalMint “also an unknowing victim”
In a statement provided to Ars today, DigitalMint said it had no knowledge of Martino’s criminal actions while he was employed there. DigitalMint said it fired the employees involved in the conspiracy after learning of the allegations from the Department of Justice, “and fully cooperated with federal authorities throughout the investigation.”
“The actions of Martino and his co-conspirators were deliberately concealed from DigitalMint and were in clear violation of the company’s values, ethical standards, and the law,” DigitalMint said. “The government has now publicly made it clear that DigitalMint was also an unknowing victim of these crimes.”
DigitalMint said Martino evaded the company’s internal safeguards that attempt to prevent fraud.
“DigitalMint maintained controls consistent with industry standards, including background checks and compliance procedures, but Martino intentionally hid his conduct from the company, including through separate, unauthorized communication channels that the government’s filings describe as accessible only to Martino and the BlackCat negotiators and affiliates,” DigitalMint said. “When federal authorities brought the allegations to the company’s attention, DigitalMint acted immediately.”
Sygnia told CNN and other media outlets in November that it terminated Goldberg “immediately upon learning of the situation.” Sygnia said the company itself was not a target of the investigation and that it was working closely with the FBI.
