The U.S. Cybersecurity and Infrastructure Agency (CISA) has urged a “Shields Up” defense in depth approach, as Russian use of wiper malware in the Ukrainian war escalates. The Russian malware “HermeticWiper” and “Whispergate” are destructive attacks that corrupt the infected computers’ master boot record rendering the device inoperable. The wipers effectuate a denial of service attack designed to render the device’s data permanently unavailable or destroyed. Although the malware to date appears to be manually targeted at selected Ukrainian systems, the risks now escalate of a spillover effect to Europe and the United States particularly as to: (i) targeted cyber attacks including on critical infrastructure and financial organizations; and (ii) use of a rapidly spreading indiscriminate wiper like the devastating “NotPetya” that quickly moves across trusted networks. Indeed, Talos researchers have found functional similarities between the current malware and “NotPetya” which was attributed to the Russian military to target Ukranian organizations in 2017, but then quickly spread around the world reportedly resulting in over $10 billion dollars in damage.[1] The researchers added that the current wiper has included even further components designed to inflict damage.

Ransomware basics

Ransomware is a serious form of cyber extortion that employs malware to prevent users from accessing their systems or data, either by locking the system or encrypting critical files until a ransom is paid. The hacker holds the key to unlock the system and usually demands payment in cryptocurrency.

Ransomware has been a known cyber threat vector for over a decade. In recent years, hackers have embraced increasingly sophisticated methods to exploit vulnerabilities and introduce ransomware into systems. They have also expanded the scope of impact by targeting ...
