Background for this topic.
Coverage under this tag concerns a named threat actor or intrusion set: an individual, group, or organized operation assessed to be responsible for malicious cyber activity. Reports may describe incidents, malware, attack infrastructure, disruption efforts, or analyst assessments. Attribution is often provisional, so actor names and reported links should be treated as intelligence judgments rather than established identity, nationality, sponsorship, or motive.
For defenders, such reporting can help connect incidents and prioritize monitoring, but indicators and techniques may be reused or become obsolete. Validate reported infrastructure, hashes, and behaviors against local telemetry; use confirmed weaknesses to guide vulnerability remediation and access controls. If activity is suspected, preserve relevant logs and evidence, contain affected accounts or systems, and coordinate investigation without relying on an actor label alone.
A new threat actor is racking up victims and showing unusual agility. Part of its success could spring from the use of the Nim programming language.
Accidentally typing a password in the username field of the platform saves them to audit logs, to which threat actors can gain access and use to compromise enterprise services.
Threat actors are using legitimate network assets and open source code to fly under the radar in data-stealing attacks using a set of custom malware bent on evasion.
