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.

Threat actors can easily steal one-time passwords sent by text when they conduct a SIM swap attack. This can lead to account takeovers, so users must layer up their security measures.
