Saint Bear G1031
Also known as Storm-0587, TA471, UAC-0056, Lorec53.
Saint Bear is a Russian-nexus threat actor active since early 2021, primarily targeting entities in Ukraine and Georgia. The group is notable for a specific remote access tool, Saint Bot, and information stealer, OutSteel in campaigns. Saint Bear typically relies on phishing or web staging of malicious documents and related file types for initial access, spoofing government or related entities. Saint Bear has previously been confused with Ember Bear operations, but analysis of behaviors, tools, and targeting indicates these are distinct clusters.
Documented targeting: 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 0 of 18 of this actor's documented techniques today (0%). 5 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.
