AppleJeus G1049
Also known as Gleaming Pisces, Citrine Sleet, UNC1720, UNC4736.
AppleJeus is a North Korean state-sponsored threat group attributed to the Reconnaissance General Bureau. Associated with the broader Lazarus Group umbrella of actors, AppleJeus has been active since at least 2018 and is closely aligned in resources with TEMP.hermit, another DPRK-affiliated group under the same umbrella. The group’s primary mission is to generate and launder revenue to provide financial support to the government. AppleJeus primarily targets the cryptocurrency industry and is most notably responsible for the 3CX Supply Chain Attack. The group traditionally deploys malicious cryptocurrency software in combination with Phishing. From these compromised environments, it selectively deploys additional backdoors to enable extended operations against high-value financial targets.
Documented targeting: Financial Services, Government
Methodology
Relevance is a match on your industry sector and technology stack against the MITRE ATT&CK v19.1 group graph (174 groups, 821 software families, 56 campaigns). It is computed deterministically from that data, with no language model in the request path. It is a relevance match, not threat-intelligence probability data: it tells you which documented actors and techniques are worth emulating for an org like yours, not a forecast that any specific group will act.
TurboPentest can autonomously exercise 1 of 24 of this actor's documented techniques today (4%). 7 are out of scope for automated testing (social engineering, denial of service, physical).

These counts are computed from the vendored MITRE ATT&CK graph and the published coverage map, and are reproducible from source.
