Ransomware Criminals Claim To Have Stolen Deloitte's Data
A ransomware group which focuses uses phishing and spear phishing exploits, known as Brain Cipher, claims to have stolen 1TB of data from Deloitte, the leading multinational firm.
Deloitte have responded that, while they aware of the claims made by the threat actor, their network systems have not been affected.
Deloitte operate a multinational professional services network, one of the so-called “big four” accounting and audit firms, and include Cyber Risk in their range of services.
Brain Cipher has listed the Deloitte UK affiliate on its victim site on the Dark Web and claims to have stolen more than 1TB of compressed data, including countdown timer with their post which gives the company less than 11 days to react. It has until December 15th, 2024.
“Unfortunately, giant companies do not always do their job well,” Brain Cypher claim. They also say that Deloitte did not observe “elementary points” of information security and threatens to release more information about the incident, data samples, and others. “We will show excellent (not) monitoring work, and tell what tools we used, and use there today,” the gang said on the Dark Web.
According to SentinelOne, Brain Cipher targets multiple critical industries and governmental organisations and engages in multi-pronged extortion. It posts victims on its TOR-based data leak site, and its malicious payloads are based on LockBit, a threat group which has now been dissolved by international law enforcement.
It is though that that Brain Cipher's claim relates to a single client’s system which sits outside of the Deloitte network.
