Darky Lock Ransomware: In-Depth Analysis, Detection, and Mitigation
Darky Lock ransomware belongs to the category of commodity-tier ransomware and is built upon the publicly accessible Babuk source code. The emergence of the Darky Lock family was initially detected in July 2022 when infecting systems with Darky Lock, the operators’ first objective is turning off several processes, including older Intuit QuickBooks and Symantec antivirus versions.
Target and Methods
Darky Lock ransomware demonstrates a broad targeting approach, aiming at large enterprises, high-value targets, and small to medium-sized businesses (SMBs).
Darky Lock ransomware employs various methods to infect its victims, including trojanized downloads and phishing emails. Additionally, they distribute malicious payloads through third-party frameworks like Empire, Metasploit, and Cobalt Strike. This wide range of attack vectors allows them to cast a wider net and increase the chances of successful infections across different types of organizations.
