01Isolate the suspected endpoint.
02Preserve volatile / forensic evidence where appropriate.
03Identify the XWorm process and associated process tree using approved EDR/forensic tools.
04Review persistence mechanisms.
05Identify C2 connections.
06Determine the initial access vector.
07Review downloaded secondary payloads.
08Assess whether browser credentials were accessible.
09Assess cookies / session tokens.
10Review cryptocurrency-wallet / browser-extension exposure.
11Change credentials from a separate trusted device.
12Revoke affected sessions.
13Enable / reconfigure MFA where appropriate.
14Review email accounts for follow-on compromise.
15Investigate lateral movement.
16Reimage systems where required by organizational policy.
17Continue monitoring for recurrence.
After containment
Credential reset, session revocation, and wallet security review are critical because XWorm's credential-theft and session-hijacking capabilities may have already exfiltrated sensitive data before the malware was removed.
