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-01Ransomware 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 memorysp-01 never isolatedCISA advises disconnecting rather than powering down: keys and the attacker's tooling live in memory.
- Fail · Protect backups before the attacker stops themBackups never lockedOperators 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 restoreA 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 reconnectingNever reconnectedDumped credentials and the unpatched SharePoint entry let the operator walk straight back in.
- Fail · Notify legal and report to CISA/FBINo reportReporting is part of the CISA checklist and often a legal or insurance obligation.
- Pass · No ransom paid (critical)Not paidPayment funds the operator, guarantees nothing, and here a clean restore was available.
