LazyScripter

Also known asLazyScripter

LazyScripter is a named threat actor tracked in the provided content as using open-source remote access Trojans in its operations, including hosting those RATs on GitHub. The actor has used spam or spearphishing-style emails weaponized with archive or document attachments to lure users into opening malicious files as an initial infection vector. Observed execution tradecraft includes use of PowerShell scripts, JavaScript, and batch files, with batch files used to deploy open-source and multi-stage RATs. For persistence, LazyScripter has written a PowerShell script to an autorun registry key. The content also associates LazyScripter with UDL-file-based spearphishing attachment activity. ATT&CK techniques directly referenced in the content for LazyScripter include T1059.001 (PowerShell), T1027.010 (Command Obfuscation), T1190 (Exploit Public-Facing Application), T1608.001 (Upload Malware), and T1608.002 (Upload Tool). No additional aliases, sub-groups, or nation-state attribution are provided in the content.

Associated malware families

FamilyContextEvidenceLast seen

Cobalt StrikeDetects the PowerShell pattern used at the end of a Cobalt Strike PowerShell loader to perform the decompression of the executable. This loader is used in attacks such as scripted web delivery. Cobalt Strike is a legitimate, commercial penetration testing tool that has been largely co-opted by ransomware gangs to launch attacks. Cobalt Strike's popularity is mainly due to its beacons or payload being stealthy, and easily customizable. Cobalt Strike Beacon provides encrypted communication with the C&C server to send information and receive commands.1May 6, 2026

NetSupport RMMThe following analytic detects the loading of specific dynamic-link libraries (DLLs) associated with the NetSupport Remote Manager (RMM) tool... This helps to identify instances where the legitimate NetSupport tool is being misused by adversaries as a Remote Access Trojan (RAT).1Mar 17, 2026

NishangThe following analytic detects the use of the Nishang Invoke-PowerShellTCPOneLine utility, which initiates a callback to a remote Command and Control (C2) server.1Mar 17, 2026

CVE-2025-9491Microsoft Windows LNK File UI Misrepresentation Remote Code Execution VulnerabilityIn the wildEvidence2

This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
