## Initial Access Analysis

**Context:** The first alert in the operation was triggered by the detection of suspicious software installations on multiple endpoints within Russian financial institutions.

**Findings:**
- The software in question was identified to have been delivered via phishing emails containing malicious attachments.
- The malware is confirmed to be a variant of the RTM Group's banking trojan, often disguised as legitimate financial software.
- Indicators of compromise (IOCs) include unusual file hashes and registry changes linked to the trojan.

**Next Steps:**
- Monitor for any unusual script executions on affected workstations, which may signal further execution of the trojan.
