How to Respond to a Ransomware Attack: Step-by-Step for Houston Businesses

Ransomware attacks are traumatic events. Business owners who have never practiced incident response make costly mistakes in the first critical minutes — decisions that determine whether they pay six figures in ransom or recover cleanly. This guide tells you exactly what to do if ransomware hits your Houston business.

Step 1: Isolate Immediately (First 5 Minutes)

The moment you suspect ransomware, physically disconnect infected devices from the network. Pull the ethernet cable. Disconnect WiFi. Do not shut the device down — the running memory may contain forensic evidence (encryption keys) that can help with recovery. If you cannot identify which devices are infected, disconnect your entire network switch to prevent spread while you investigate. Every minute of delay allows ransomware to encrypt more files and spread to more systems.

Step 2: Call Your IT Provider (Minutes 5-15)

Call SpaceTown IT at (832) 304-9748 immediately — do not attempt to investigate or remediate yourself. Your IT provider will: triage which systems are affected, contain the spread through network isolation, begin forensic investigation, initiate the backup recovery process, and document the incident for insurance and legal purposes.

Step 3: Do Not Pay Ransom Without Consulting Experts

Before paying any ransom, consult your IT provider, cyber insurance carrier, and legal counsel. Reasons to pause before paying: (1) Payment does not guarantee decryption — 25% of ransomware victims who pay do not get usable decryption keys, (2) Paying funds criminal organizations and may violate OFAC sanctions if the group is sanctioned, (3) If you have good backups, you may not need to pay at all.

Step 4: Notify Required Parties

Ransomware attacks may trigger mandatory notification requirements: cyber insurer (usually within 24-72 hours), legal counsel (attorney-client privilege protects your investigation), state breach notification if personal data was affected (Texas requires notification within 60 days for certain breaches), HIPAA-covered entities must notify HHS and affected individuals within 60 days.
