Lockbit leak sites hit by mysterious DDoS attack after Entrust hack

Pierluigi Paganini August 23, 2022

LockBit ransomware gang claims to have hacked the IT giant Entrust and started leaking the stolen files.

Entrust Corp., provides software and hardware used to issue financial cards, e-passport production, user authentication for those looking to access secure networks or conduct financial transactions, trust certificated for websites, mobile credentials, and connected devices.

The Lockbit ransomware gang claimed to have hacked the company and is threatening to leak the stolen files. The name of the company has been added to the LockBit 3.0 Tor leak site.

Cybersecurity researcher Dominic Alvieri published a notice sent to Entrust customers on July 6, which inform them that some files were taken from its internal systems.

Initially, the group fixed the deadline for the payment of the ransom on August 19, at the time of this writing the group started leaking the files.

The group published tens of screenshots of allegedly stolen Entrust data, including accounting, legal, and marketing data.


The news of the ransomware attack against Entrust made the headlines in July, the security breach was also confirmed by Entrust.

“We promptly began an investigation with the assistance of a leading third-party cybersecurity firm and have informed law enforcement,” Ken Kadet, vice president of communications at Entrust, said in a statement. “While our investigation is ongoing, we have found no indication to date that the issue has affected the operation or security of our products and services, which are run in separate, air-gapped environments from our internal systems and are fully operational.”

Curiously, the LockBit ransomware’s Tor leak sites were unreacheable due to a DDoS attack. The attack was launched by a threat actor ordering Lockbit gang to remove Entrust’s stolen data.

According to the security research group VX-Underground, the DDoS attacks against Tor sites of the gang were launched by someone linked to Entrust.

HTTPS requests sent by the attackers included a message to LockBit group in the browser user agent field ordering them to delete Entrust’s data.

The news was confirmed by BleepingComputer who reached representatives from the group:

“Ddos attack began immediately after the publication of data and negotiations, of course it was them, who else needs it? In addition, in the logs there is an inscription demanding the removal of their data,” LockBitSupp told BleepingComputer.

The Lockbit group shared negotiations with Entrust with the security researcher Soufiane Tahiri. This chat reveals that the gang initially demanded an $8 million ransom, and dropped to $6.8 million later.

BleepingComputer also reported that LockBitSupp told them that another victim in the past, Accenture, conducted a similar attack against their data leak sites, but without success.

LockBit operators also announced to have stolen dats from the US engineering giant Wabtec.
