Cyberattacks against PLC systems, ICS devices, and OT networks are increasing in volume and variety as nefarious activities of three new cybercriminal outfits have come under the scanner of researchers. Tracked as Kostovite, Petrovite, and Erythrite, these new groups are actively targeting organizations in the energy sector to gain direct access to the firms’ infrastructure, move laterally, and steal data.

A unique covert hacking tool used by the Equation Group threat actors has also been unraveled by security experts. Dubbed Bvp47, the malicious implant sports a two-way communication mechanism to exfiltrate sensitive data. Furthermore, in a major revelation, researchers have 
unearthed similarities between the Dridex trojan and a little-known ransomware called Entropy.
