Combatting the ‘Death Note’-inspired ransomware

So, here’s why Ryuk has been a preferred method of attack and what can be done to prevent and discourage attackers from cashing out their ill-gotten gains on major exchange platforms.

The Trojan at the city gates: Ryuk

These newer vectors of attack mentioned in Kaspersky’s July report have not quite garnered the same reputation as the Ryuk ransomware. Toward the end of 2019, Kaspersky released another report that highlighted the plight of municipalities and cities that have fallen prey to ransomware attacks. Ryuk was identified by the…
