When your computer systems are suddenly encrypted, locked, or displaying ransom notes, every minute matters. At On-Site Louisville Computer Repair Company, we provide fast, professional Incident Response Services for businesses and residential customers throughout Louisville and the surrounding areas. We have direct experience and can provide references from customers we have recovered from cyberattacks. If you are experiencing ransomware, unauthorized remote access, suspicious activity, or encrypted files we can respond immediately. We have current experience (2026) dealing with this problem on-site at a law office and other businesses and were able to recovery files that others could not recover.
What Is Incident Response?
Incident response is the rapid identification, containment, and remediation of a cybersecurity breach or attack.
Common incidents include:
-
Ransomware infections or manual drops of ransomware via your network other lateral methods(including file encryption)
-
Servers suddenly encrypting files or clients and workstations being encrypted
-
Servers or Workstations displaying ransom notes
-
Unauthorized remote logins (RDP compromise)
-
Suspicious network-wide file changes
-
Data breaches or attempted data exfiltration, deletions or threats
-
Business email compromise or phishing attacks
If your server or office network has been attacked, do not reboot repeatedly or begin deleting files. Immediate professional containment is critical. This is the point to call us, not later.
What To Do Immediately If You’re Under Attack
If you suspect ransomware or hacking:
-
Disconnect the infected machine from the network immediately (pull Ethernet cable and/or disable Wi-Fi)
-
Do NOT pay the ransom
-
Do NOT wipe the system yet
-
Do NOT allow further remote access
-
Call us right away at (502) 963-3981
Fast containment can prevent the infection from spreading to additional machines.

Signs You Have Been Hacked
-
Files renamed with unfamiliar extensions are a major warning sign of ransomware. Common examples include .locky (associated with Locky), .crypt and .crypto (used by multiple crypto-based strains), .encrypted (a generic marker), .cryptolocker (linked to CryptoLocker), .ryuk (from Ryuk), .maze (from Maze), .revil or randomized extensions (associated with REvil), .conti (from Conti), and .inc, which has been used by the INC ransomware group. If you see files suddenly renamed with any of these extensions — especially across a shared drive or server — it typically indicates active or completed encryption and requires immediate containment.
