What is LockBit?

LockBit is each a cyberattack group and a malicious software program used to hold out prison assaults.

LockBit, the group, operates as a ransomware-as-a-service business, the place groups develop malware that’s licensed to affiliate networks, which use it to hold out assaults, stated Sumit Bhatia, the director of innovation and coverage on the Rogers Cybersecure Catalyst at Toronto Metropolitan University.

Security software program firm BlackBerry’s web site says LockBit malware infiltrates its targets’ networks by means of unpatched vulnerabilities, insider entry and zero-day exploits — flaws in software program found earlier than the corporate which created it realizes the issue, giving them “zero days” to repair it.

LockBit is then capable of set up management of a sufferer’s system, accumulate community data and steal or encrypt information, the positioning stated.

“LockBit attacks typically employ a double extortion tactic to encourage victims to pay, first, to regain access to their encrypted files and then to pay again to prevent their stolen data from being posted publicly,” BlackBerry stated.

How prolific is LockBit?

LockBit has made not less than $100 million in ransom calls for and extracted tens of hundreds of thousands of {dollars} in funds from victims, stated a courtroom doc filed within the District of New Jersey in a 2022 case towards a suspected LockBit member.

LockBit emerged as early as January 2020 and members have since executed not less than 1,000 LockBit assaults towards victims within the U.S. and around the globe, the doc alleged.

Who is behind LockBit?

That’s a tough query, stated Bhatia, as a result of “these folks operate in such shadows.”

“But what we understand largely is that there’s a deep connection to Russia and to former members of the Russian community, who may not necessarily be based out of Russia anymore, but could be operating from a series of different locations across Europe, and form a part of this large network that LockBit has launched,” he added.

That means LockBit members may very well be situated anyplace on this planet. In November, for instance, the U.S. Department of Justice charged twin Russian and Canadian citizen Mikhail Vasiliev in connection along with his alleged participation in a LockBit ransomware marketing campaign.

Was Indigo’s cyberattack carried out by the LockBit gang or somebody utilizing LockBit software program?

Indigo has stated its community was “accessed by (alleged) criminals who deployed ransomware software known as LockBit,” however added it doesn’t know particularly who’s behind the assault.

LockBit’s different victims embrace the U.Ok.’s Royal Mail, French know-how group Thales and the Lisbon Port Authority in Portugal.

What can corporations do to keep away from being a sufferer to a LockBit assault?

LockBit depends totally on phishing assaults, stated Bhatia.

Phishing usually begins with fraudulent emails or textual content messages meant to appear to be they have been despatched by a reliable firm. They usually dupe individuals into coming into confidential data reminiscent of passwords right into a fraudulent web site or downloading malware onto a pc with entry to an organization’s community.

“Ransomware, especially through phishing, does often come down to the human element,” stated Bhatia.

That means one of the best ways to cease it’s to make sure that workers are cautious and perceive methods to evaluate hyperlinks and messages they get to keep away from scams.

“It’s really understanding how to be on the lookout for something that is seen as suspicious,” Bhatia stated.

Is it a good suggestion to pay attackers to entry your system or decrypt information and information should you’re attacked with ransomware?

“From a law enforcement perspective, organizations are encouraged not to pay and that’s … because you’re not really guaranteed, even after paying that you’re not going to be affected adversely,” Bhatia stated.

“You can’t really rely on the commitments being made by these attackers.”

Authorities additionally discourage paying as a result of it encourages criminals to proceed their assaults and propagates a cycle, he stated.

However, he famous “small businesses don’t always have the luxury of not paying or those that are working with critical sectors, where access to that data or access to those systems is critical and can have a severe adverse effect.”

Indigo has refused to pay its attackers, who the corporate stated deliberate to submit on the darkish internet the worker information it stole.

“The privacy commissioners do not believe that paying a ransom protects those whose data has been stolen, as there is no way to guarantee the deletion/protection of the data once the ransom is paid,” Indigo stated on its web site.

“Additionally, we cannot be assured that any ransom payment would not end up in the hands of terrorists or others on sanctions lists.”
