LightPeek

LightPeek is an information-stealing malware family written in PowerShell. In the provided reporting, it is described as a stealer that captures screenshots and collects file lists. It was identified by S2W TALON as one of more than nine malware samples used in a campaign targeting South Korean users and organizations. That campaign used phishing lures themed as postal-code or address update notices, with a malicious LNK file embedded in a RAR archive as the initial infection vector; execution led to an AutoIt loader that retrieved additional payloads from an external server. LightPeek was deployed alongside other malware including FadeStealer, NubSpy, CHILLYCHINO, TxPyLoader, and VCD ransomware. The activity is attributed by the cited researchers to ChinopuNK, a subgroup of ScarCruft/APT37, a North Korean state-sponsored threat actor. High-confidence behaviors directly mentioned for LightPeek are screenshot capture and file-list collection; no specific indicators of compromise are provided in the content.
