Analysis of the Rubrik facts theft
It is not unheard of for ransomware groups to steal details and keep away from deploying a locker – the destructive payload that blocks a sufferer from accessing their information.
Given the increase – and resultant good results- of the double extortion ransomware model in recent many years, some groups have opted for a simple extortion-only strategy when it will come to attacks.
This signifies they will breach a company’s techniques, steal facts, and hold the details to ransom only, leaving the enterprise with total obtain to its programs.
A noteworthy example of this was the LAPSU$ group which rose to prominence in early 2022. Originally considered to be a rival ransomware operation, hacks on massive providers like Nvidia and Samsung uncovered that they adopted an extortion-only model.
It appears Rubrik’s incident is 1 of these, uncharacteristic of the Cl0p team which is regarded for deploying lockers in its attacks.
Organisations that are accused of struggling ransomware attacks while earning no mention of ‘ransomware’ in their explanations frequently increase issues about why they make your mind up not to use the terminology.
In this circumstance, Rubrik created no point out of ‘ransomware’ in any of its communications, possibly to the public or straight to the media.
It is not unusual for victims to distance them selves from the time period ‘ransomware’ to keep away from the reputational damage that comes with these attacks.
It remains unclear whether ransomware was associated in the Rubrik incident or not. The organization has neither confirmed nor denied the existence of ransomware in its responses to the general public and to IT Pro privately.
It would be unusual for the Cl0p group to not deploy a locker in an attack, but not solely unachievable both.
