According to the Cybersecurity & Infrastructure Security Agency (CISA), there are “16 critical infrastructure sectors whose assets, systems, and networks are considered so vital that their incapacitation or destruction would have a debilitating effect on security, national economic security, national public health or safety, or any combination thereof”. Cyber attacks against critical infrastructure, including healthcare institutions, have become high-value targets for ransomware gangs looking to cause systemic disruption and societal chaos.

Conti, also known as Ryuk, has increased its focus on targeting Canadian companies following the shutdown of the REvil/Sodinokibi ransomware gang at the hands of the U.S. law enforcement agencies. The Conti group uses the “double extortion” ransomware tactic against its victims. They not only encrypt the victim’s data but also threaten to sell it to other threat actors if they don’t get paid the ransom demand. Recently Conti’s affiliate program appears to have pivoted from publishing and selling its victim’s stolen files to selling access to many of the organizations it has hacked.

Currently, over 50% of eSentire customers operate within the critical infrastructure segments recognized by CISA.
