Singapore's Cyber Security Agency (CSA) has issued a stark warning to businesses about a new strain of ransomware known as "Akira." It is kind of unusual. Instead of fiat money, it demands victims to pay the ransom in Bitcoin.
Just as you would expect, Akira ransomware encrypts victim data, rendering it inaccessible.
Attackers then demand some amounts of Bitcoin as ransom to decrypt the data. Once they get paid, the data gets unlocked. But that's not a 100% guaranteed, of course.
The ransomware attacks only Windows PCs. As it often happens, Mac OS devices are not targeted.
The report underscores the importance of incident response planning. Companies should be prepared to act swiftly in the event of a ransomware attack. This includes having clear protocols for isolating infected systems and communicating with stakeholders.
Authors of the report also note that ransomware attacks have become increasingly sophisticated. Attackers are using advanced techniques to avoid detection and maximize impact.
The CSA encourages businesses to report ransomware incidents. Sharing information about attacks can help in understanding and countering the threat landscape. Using victim's experience other market participants can take measures to avoid the attack. And thus withstand ransomware more effectively.
