Response

What has happened

    Result: FAIL · 10/100

    Pass needs 70 and every critical gate. Gates grade the whole response, so finish before reading them.

    • Fail · Contain before the file server is encrypted (critical)
      Encrypted: sp-01, fs-01, ws-114, ws-207, bkp-01
      Ransomware damage scales with every minute of spread; isolating the beachhead is the first CISA response step.
    • Fail · Isolate the network; don't power off before capturing memory
      sp-01 never isolated
      CISA advises disconnecting rather than powering down: keys and the attacker's tooling live in memory.
    • Fail · Protect backups before the attacker stops them
      Backups never locked
      Operators delete shadow copies and disable backups before encrypting so victims can't recover without paying.
    • Fail · Restore from a clean point that predates the intrusion (critical)
      No restore
      A point taken after initial access still carries the web shell; only a pre-intrusion, attacker-unreachable copy is trustworthy.
    • Fail · Reset credentials and patch the entry before reconnecting
      Never reconnected
      Dumped credentials and the unpatched SharePoint entry let the operator walk straight back in.
    • Fail · Notify legal and report to CISA/FBI
      No report
      Reporting is part of the CISA checklist and often a legal or insurance obligation.
    • Pass · No ransom paid (critical)
      Not paid
      Payment funds the operator, guarantees nothing, and here a clean restore was available.
