CASE FILE / INCIDENT RESPONSE
Ransomware contained before payroll ran
A regional financial-services group detected anomalous encryption at 02:00. A retained OpasSecure team took command and resumed clean operations the same business day.
CHALLENGE
A wave that started at 02:00
An endpoint began encrypting file shares overnight. On-call staff noticed jobs failing but couldn’t tell scope from impact — exactly the moment most organizations lose hours.
RESPONSE
Acknowledge, isolate, trace
The retainer line acknowledged within minutes. We isolated affected hosts, traced the intrusion to a single compromised credential, and preserved forensic images before anything was rebuilt.
OUTCOME
Same-day clean operations
Systems were restored from verified-clean backups, the entry point was closed, and the client received a documented evidence trail suitable for regulators and insurers.

First alert to full containment

Ransom paid
same day
Clean operations resumed
We treated the incident as a case file from minute one — that discipline is why the client had answers, not just recovery.
