PureLog is a Windows-focused information stealer associated with financially motivated malware delivery ecosystems that commonly use ClickFix and fake CAPTCHA social-engineering lures. It is frequently delivered as a follow-on payload in multi-stage intrusion chains alongside other stealers and remote access trojans, including Lumma, RedLine, Vidar, NetSupport, XWorm, AsyncRAT, and Quasar. Observed delivery activity in this ecosystem relies on users executing malicious clipboard-pasted commands, typically through PowerShell, after interacting with deceptive verification pages or similarly themed lures.
PureLog has been referenced as part of campaigns that use layered loaders, obfuscated scripting, Windows Management Instrumentation-launched PowerShell, steganographic retrieval of .NET components, trojanized libraries, and process hollowing to deploy final payloads. It also appears in delivery clusters tied to two-archive runtime-plus-payload packaging associated with PureHVNC/PureLog and Amatera stealer activity. These tradecraft patterns indicate an ecosystem built for flexible payload substitution and staged deployment rather than a single fixed infection chain.
At high confidence, PureLog is best characterized as an infostealer used to collect and exfiltrate victim information from compromised Windows systems. It is not confidently attributable here to a specific threat actor, but it is consistently associated with cybercrime-oriented distribution operations targeting end users through social engineering and malware-as-a-service style delivery infrastructure.
