Advanced, a managed software provider to the UK National Health Service, has confirmed that customer data was indeed lifted as part of the attack by cyber baddies that has disrupted operations for months. The incident disrupted healthcare customers, forcing NHS 111 medical services operators, for example, to revert back to pen and paper as digital services went AWOL, sources told us at the time.

Lockbit ransomware affiliates are encrypting victims via Microsoft Exchange servers hacked using exploits targeting unpatched vulnerabilities. In at least one such incident from July 2022, the attackers used a previously deployed web shell on a compromised Exchange server to escalate privileges to Active Directory admin, steal roughly 1.3 TB of data, and encrypt network systems.

The relatively new Bl00Dy Ransomware Gang has started to use a recently leaked LockBit ransomware builder in attacks against companies. Last week, the LockBit 3.0 ransomware builder was leaked on Twitter after the LockBit operator had a falling out with his developer.

This week we saw some embarrassment for the LockBit ransomware operation when their programmer leaked a ransomware builder for the LockBit 3.0 encryptor. Ransomware operations were launched in the past from the leaks of the Babuk ransomware builder and Conti source code.

The LockBit ransomware operation has suffered a breach, with an allegedly disgruntled developer leaking the builder for the gang's newest encryptor. After security researcher 3xp0rt shared the tweet about the leaked LockBit 3.0 builder, VX-Underground shared that they were contacted on September 10th by a user named 'protonleaks,' who also shared a copy of the builder.

The DDoS attack last weekend that put a temporary stop to leaking Entrust data was seen as an opportunity to explore the triple extortion tactic to apply more pressure on victims to pay a ransom. LockBitSupp said that the ransomware operator is now looking to add DDoS as an extortion tactic on top of encrypting data and leaking it.

LockBit ransomware gang announced that it is improving defenses against distributed denial-of-service attacks and working to take the operation to triple extortion level.The gang has recently suffered a DDoS attack, allegedly on behalf of digital security giant Entrust, that prevented access to data published on its corporate leaks site.

The LockBit ransomware group last week claimed responsibility for an attack on cybersecurity vendor in June. LockBitSupp, the public face of LockBit that interacts with companies and cybersecurity researchers, told Shukuhi that the group's data leak site was getting 400 requests a second from more than 1,000 servers and that the group promised to add more resources to the site and to "Drain the ddosers money," he wrote.

The LockBit ransomware operation's data leak sites have been shut down over the weekend due to a DDoS attack telling them to remove Entrust's allegedly stolen data. Soon after they started leaking data, researchers began reporting that the ransomware gang's Tor data leak sites were unavailable due to a DDoS attack.

This post was originally published on August 18th. The LockBit ransomware gang has claimed responsibility for the June cyberattack on digital security giant Entrust. Today, security researcher Dominic Alvieri told BleepingComputer that LockBit had created a dedicated data leak page for Entrust on their website, stating that they would publish all of the stolen data tomorrow evening.
