You open your computer Monday morning and see a ransom note. Your files are encrypted. Your server is down. Your team can't work. This is the nightmare scenario — and it's happening to Houston businesses with increasing frequency. The actions you take in the first 24 hours are critical. Panic leads to mistakes that make recovery harder and more expensive. This is the exact incident response playbook our team follows when a Houston client calls us with a ransomware attack.
Hour 0-1: Contain the Damage Immediately
The moment you suspect ransomware, disconnect affected systems from the network. Unplug ethernet cables, disable Wi-Fi, and isolate any device showing signs of encryption. Do NOT turn off the computers — this can destroy forensic evidence and may actually make recovery harder with some ransomware variants. Call your IT provider immediately. If you don't have one, call Implex IT at 346-330-5105. Time is critical — ransomware spreads laterally through networks, and every minute of delay means more encrypted files.
Hour 1-4: Assess the Scope
Once contained, assess what's been affected. Which systems are encrypted? Which are clean? Is your backup system intact? (Ransomware often targets backups first.) Document everything — take photos of ransom notes, note which systems are affected, and preserve logs. This documentation is critical for insurance claims, law enforcement reports, and forensic investigation. Contact your cyber insurance carrier — most policies require notification within 24-72 hours of discovery.
Hour 4-12: Identify the Ransomware Variant
Different ransomware variants have different characteristics, and some have free decryption tools available. The No More Ransom project (nomoreransom.org) — a collaboration between law enforcement and cybersecurity companies — provides free decryptors for dozens of ransomware variants. Upload a sample of your encrypted files to identify the variant. If a free decryptor exists, you may be able to recover without paying the ransom.
Hour 12-24: Begin Recovery
If backups are intact and clean, begin the recovery process from your most recent clean backup. This is why tested, offsite backups are so critical — they're your get-out-of-jail-free card. If backups are compromised, you face a harder decision: pay the ransom (not recommended, as it funds criminal organizations and doesn't guarantee recovery) or rebuild from scratch. Law enforcement (FBI Houston field office: 713-693-5000) should be notified regardless of your recovery path.
Key Takeaways
The best ransomware response is prevention. Houston businesses with proper security controls — EDR, email security, MFA, and tested backups — rarely face catastrophic ransomware outcomes.
