Loading threat actor…
UNC5687 is a tracked threat actor associated with phishing campaigns that impersonate the Security Service of Ukraine to deliver MESHAGENT, an open-source remote access framework. Observed delivery chains use malicious links and CAPTCHA-gated lure pages that lead victims to download installer packages or executables, followed by script-based retrieval and execution of additional payloads. Tradecraft associated with the actor includes obfuscated PowerShell downloaders, staged payload delivery, and remote-access enablement for follow-on intrusion activity. UNC5687 has been linked to campaigns in which MESHAGENT is configured to communicate with infrastructure associated with AnonVNC. Based on the observed use of phishing for malware delivery and remote administration tooling for victim access, the actor demonstrates initial access, defense evasion, persistence, and post-exploitation capability. Publicly available information in this context does not establish a confirmed nation-state attribution or broader alias set beyond UNC5687.
