MegaCortex is a type of malware known for its harmful effects on computer systems and devices. It was identified by Dragos, a cybersecurity firm, as having a relationship with another ransomware called EKANS. Both MegaCortex and EKANS have specific characteristics that pose unique risks to industrial operations not previously observed in ransomware operations. They represent hardened ransomware variants that can disrupt operations, steal personal information, or hold data hostage for ransom. Over the years, MegaCortex has been used in various cyberattacks, paralyzing major corporations' operations. In addition to MegaCortex, other ransomware such as LockerGoga, Hive, and Dharma were also deployed by cybercriminals to carry out their attacks. These criminals targeted large corporations in 71 countries, causing losses of several hundred million euros. Qakbot, also known as Qbot and Pinkslipbot, served as an initial infection vector for various ransomware gangs, including those using MegaCortex. After remaining undetected in compromised systems for months, these criminals would deploy different types of ransomware and present a ransom note to the victims, demanding payment in Bitcoin in exchange for decryption keys. However, there has been some success in combating MegaCortex and similar ransomware. Last year, decryptors for BlackCat, Hive, and MegaCortex ransomware variants were released, providing a means to recover encrypted files without paying a ransom. Additionally, Swiss authorities, along with No More Ransom and cybersecurity firm Bitdefender, developed decryption tools for LockerGoga and MegaCortex ransomware variants. This progress followed the arrest in Ukraine of five members of a group accused of using ransomware strains like Hive, LockerGoga, MegaCortex, and Dharma in attacks that netted them hundreds of millions of dollars.
