You arrive at your Tulsa office and your files are encrypted. A ransom note on the screen demands payment in cryptocurrency to restore access. Every minute your systems are down, your business is losing money, your employees cannot work, and the pressure to simply pay and move on is intense. This guide is exactly what you need in this moment: a clear, prioritized action plan written by technicians who have helped Tulsa businesses recover from ransomware attacks.

Step 1: Disconnect Immediately

The first and most critical action is isolation. Disconnect every affected device from the network by unplugging ethernet cables and disabling WiFi. Turn off network switches if possible. Ransomware spreads laterally across networks. Every second a device remains connected, more machines and shared drives can be encrypted. Do not wait to assess the damage before disconnecting. Isolate first, assess second.

Do not shut down the infected machines yet. While counterintuitive, powered-off machines may destroy volatile memory that forensic tools can use to identify the ransomware strain and potentially recover encryption keys. Leave them on but completely isolated from the network.

Step 2: Do Not Pay the Ransom

Law enforcement agencies including the FBI strongly advise against paying ransoms, and for good reason. Payment does not guarantee recovery. Research shows that over 40 percent of businesses that pay receive corrupted or incomplete decryption tools. Payment confirms to attackers that your business is a viable target, making future attacks more likely. And the funds directly finance criminal organizations.

Before paying anything, contact our emergency IT support team. Many ransomware variants have been cracked by security researchers, and free decryption tools are available for a growing list of strains. The ransomware note or encrypted file extensions can often identify the variant, which is the first step in determining whether a free recovery path exists.

Step 3: Assess What Was Hit

Once the network is isolated, inventory the damage. Which machines are encrypted? Which shared drives were accessible from those machines? Are backups affected? The answers determine the recovery path. If you have clean, recent backups stored offsite or in a cloud service that was not connected at the time of the attack, recovery may be a matter of hours rather than days.

If backups do not exist or were also encrypted (a deliberate ransomware tactic), the situation is more complex but not necessarily hopeless. Our data recovery team can assess whether file system artifacts, shadow copies, or partial data remains accessible on affected drives.

Step 4: Report the Incident

File a report with the FBI's Internet Crime Complaint Center at ic3.gov and notify the Tulsa Police Department. If your business handles personal data regulated by HIPAA, PCI-DSS, or state privacy laws, you may have mandatory breach notification obligations with strict timelines. Notify your business insurance carrier if you carry cyber liability coverage, as claims must typically be filed quickly after discovery.

Step 5: Clean and Restore Completely

Even if a decryption tool is obtained, simply decrypting files and returning to normal operations is a critical mistake. Ransomware is almost always delivered alongside other malware, including backdoors that allow the attackers to re-enter your systems after recovery. A full forensic remediation is required before your business should consider itself secure: identifying the initial infection vector, removing all malicious software, patching the vulnerability that allowed entry, and verifying system integrity.

Our team performs complete malware removal and system remediation following ransomware incidents, ensuring that your restored environment is not immediately re-compromised. We also work with you to establish the backup and monitoring infrastructure that would have shortened the impact of this attack and will prevent the next one from succeeding at all.

Ransomware attacks do not create vulnerabilities. They exploit ones that already existed. Recovery is the beginning of a security conversation, not the end of one.
