What You Need to Know About Cactus Ransomware:
2023 has marked the emergence of a new ransomware contender – Cactus. Unlike its counterparts, this ransomware exhibits a unique signature, distinguishing itself with innovative evasion techniques and a distinct encryption modus operandi.
The Origin: Cactus Ransomware made its initial appearance in March 2023. Its name originates from the filename provided in the ransom note, which is typically “cAcTuS.readme.txt”.
How Does Cactus Ransomware Infiltrate Systems?
Cactus predominantly targets VPN appliances, especially vulnerabilities within Fortinet VPNs. The trend observed across incidents indicates that unauthorized access is often obtained via a VPN server using a VPN service account. Once inside, the threat actor doesn’t waste time and initiates internal scouting using tools like SoftPerfect Network Scanner.
Cactus’ Unique Encryption Strategy:
Cactus employs a sophisticated encryption process. After securing the encryptor binary using 7-Zip, the binary is released with specific flags. This allows it to run while being shielded by its encrypted configuration, reducing chances of detection.
- Pre-encryption, files adopt the .CTS0 extension.
- Post-encryption, files take on the .CTS1 extension.
However, files might also undergo a double encryption process, leading to compounded extensions, e.g., .CTS1.CTS7.
Defensive Measures:
- Stay Updated: As Cactus capitalizes on vulnerable VPN appliances, particularly Fortinet VPNs, ensuring these are updated and patched is vital.
- Access Control: Ensure stringent controls and regular audits of VPN service accounts.
- Network Oversight: Monitor for abnormal data transfers, which could be indicative of data exfiltration attempts.

Smoke testing is a term used to describe the testing process for servers after patches are applied. 
Estimating an average time for patching servers and PCs can be a bit tricky. It can vary from one month to the next, depending upon the number and complexity of the patches released by your software vendors. You must consider all versions of operating systems and have a complete inventory of all your application software to do this job correctly. Our experience has shown that manual patching of systems takes on average of about 1.5 hours each.
This is a basic cost calculator for you to compute your typical monthly cost for patching your servers, PCs, laptops, tablets and associated application software. It also forms the basis for you to begin calculating your Return on Investment for software patching, or for comparison with alternatives to the manual process of patching operating systems and application software—such as Patch Management as a Service, also known as Vulnerability Management as a Service.
