Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
1 distinct threat actor attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
The WLDR agent is a sophisticated PowerShell-based C2 memory implant that features encrypted beaconing, task queuing, and a Runspace execution engine for executing additional payloads.
14 distinct techniques documented for this family, organized by ATT&CK tactic.
The threat actor executed a multistage campaign that involves deploying a weaponized HTA downloader via Microsoft HTML Application Host (“mshta.exe”) on the victim's machine, likely utilizing a ClickFix technique.
Talos discovered that the threat actor executed a curl command to download and execute additional PowerShell script payloads of the WLDR C2 framework from another C2.
The PowerShell stager is heavily obfuscated... The compiled Python loader is a relatively large file obfuscated with numerous junk functions... implementing XOR decryption
It performs system reconnaissance, assembling the victim profile that includes the system hardware-bound unique identifier (HWID), total RAM size of the victim machine, and installed antivirus.
The initial connection to the C2 is established through an HTTP POST... All subsequent traffic is sent to C2 over HTTPS, with headers designed to mimic a Chrome browser session.

A bespoke in-memory PowerShell remote access implant delivered through a WLDR stager/downloader chain. It uses encrypted HTTP/HTTPS C2 communications, host reconnaissance, mutex protection, reconnect logic, and a RunspacePool-based task execution engine for interactive remote PowerShell execution and modular payload delivery.
A bespoke PowerShell in-memory remote access implant delivered in this campaign as a later-stage payload. It uses encrypted HTTP/HTTPS C2 communications, host reconnaissance, mutex protection, retry/reconnect logic, and a Runspace-based concurrent task execution engine for interactive remote PowerShell operations.
