The Kill ransomware group, also known as KillSec or KillSecurity, is a cybercriminal organization. They employ a ransomware-as-a-service (RaaS) model, allowing affiliates to execute attacks using their malware infrastructure. KillSec is known for targeting various industries, including manufacturing and wholesale sectors.
KillSec’s ransomware variants, such as KillSecurity 2.0 and KillSecurity 3.0, are designed to encrypt files and demand ransom payments for decryption. The group utilizes various tactics, techniques, and procedures (TTPs) to infiltrate networks, including phishing emails, exploiting unpatched vulnerabilities, and leveraging remote desktop protocol (RDP) brute-force attacks. Organizations are advised to implement robust cybersecurity measures, including regular data backups, system updates, and employee training, to mitigate the risk of falling victim to such ransomware campaigns.
