Category | Details |
---|---|
Threat Actors | Not explicitly named, but associated with the WannaCry ransomware campaign. |
Campaign Overview | Aggressive ransomware attack targeting systems globally using the ETERNALBLUE exploit; highly virulent due to lateral movement capabilities. |
Target Regions | Global impact; specific targets not listed, but included both supported and legacy systems. |
Methodology | Exploitation of SMB vulnerability (MS17-010), propagation via lateral movement, and embedding ransomware payload in systems. |
Product Targeted | Microsoft Windows systems, including legacy operating systems like Windows XP. |
Malware Reference | WannaCry 2.0 |
Tools Used | ETERNALBLUE SMB exploit, kill-switch domains, embedded downloader scripts, UPX packer, PHP-based droppers. |
Vulnerabilities Exploited | Microsoft SMB v1.0 vulnerability (CVE-2017-0144); delayed patching in enterprise environments. |
TTPs | Lateral movement via SMB scanning, encryption of user files, use of random strings for payload obfuscation, creation of persistence mechanisms. |
Attribution | Likely associated with actors leveraging leaked NSA tools (EternalBlue). |
Recommendations | Apply security patches (MS17-010), block SMB ports 139/445, monitor kill-switch domains, isolate unpatched systems, and establish ransomware incident protocols. |
