According to computing.co.uk, “the gang’s claims are false and relate to a client’s system, not its own”.
The ransomware group Brain Cipher has claimed to have hacked Deloitte UK and threatened to release 1tb of stolen data earlier this week.
Hackers post read,
“Soon we will tell you about this incident.
“We will provide an example of data that has leaked.
“The volume of compressed data [is] more than 1tb.”
Brain cipher Group said, “We will show excellent (not) monitoring work, and tell what tools we used, and use there today.”
According to WatchGuard, the group uses a slightly modified version of the LockBit 3.0 builder for its encryption tool.
“Not affecting the target organization’s systems doesn’t mean there’s no impact,” Javvad Malik, lead security awareness advocate at KnowBe4, told Infosecurity. “The mere suggestion of a breach can harm reputations, affect stock prices, or trigger costly and unnecessary responses. Thus, even an empty threat carries the same weight as shouting ‘fire’ in a crowded theatre.”
Deloitte’s Response:
Deloitte UK has not confirmed or denied the breach publicly, and cybersecurity experts are monitoring the situation for updates.
Deloitte experienced another cyber incident recently, IntelBroker to claim to have leaked internal communications.
IntelBroker, the leader of the CyberN—–s ransomware gang, claims to have obtained email addresses, internal communications, and other internal company settings.
Deloitte accidentally exposed an Apache Solr server to the internet, leading to the breach, reported cyberdaily.au.
The group uses various extortion tactics to pressure victims and operates a TOR-based site to publish breaches and stolen data.
Brain Cipher ransomware attacks various critical sectors like healthcare, education, and manufacturing, as well as government and law enforcement. A notable incident was the attack on Indonesia’s National Data Center, which disrupted public services including immigration and student registration.
