Ransomware Data Recovery: How to Recover Encrypted Data After a Ransomware Attack
Ransomware is one of the most harmful types of cyberattacks, where malicious software (malware) encrypts your data and demands a ransom in exchange for a decryption key. Whether you’re an individual or a business, ransomware can be devastating, as it can make critical files, systems, and databases inaccessible. In this guide, we’ll explain how ransomware works, what steps to take after an attack, and how ransomware data recovery services can help you retrieve encrypted files without paying the ransom.
What Is Ransomware?
Ransomware is a form of malware that encrypts files on a victim’s computer or network. Once the encryption is complete, the attacker demands a ransom (usually in cryptocurrency like Bitcoin) in exchange for the decryption key that would unlock your files. We can recover your data from Locky, CryptoWall, CryptoWall 3.0, CryptoWall 4.0, DMA Locker, CryptoLocker, LeChiffre, CryptXXX, CTB Locker, Maktub, TorrentLocker, KeRanger, CryptoHost, TeslaCrypt, Coverton, Cerber.
Most Common Types of Ransomware:
- Crypto Ransomware: Encrypts your files, making them inaccessible without a decryption key.
- Locker Ransomware: Locks you out of your entire system without encrypting files. The system remains inoperable until a ransom is paid.
- Double Extortion Ransomware: Encrypts your data and steals it. Attackers threaten to publish your stolen data unless the ransom is paid.
Steps to Take After a Ransomware Attack
If your system has been infected with ransomware, quick action is critical to minimize damage and improve your chances of recovering your data. Follow these steps immediately:
1. Disconnect from the Network
Immediately isolate the infected system by disconnecting it from the internet and local network to prevent the ransomware from spreading to other systems or servers.
2. Identify the Ransomware Strain
Identifying the specific ransomware strain helps determine if there are decryption tools or recovery options available.
- How to Identify Ransomware:
- Ransom Note: Check the ransom note for clues about the type of ransomware. Often, the note includes the ransomware strain’s name or email contact details.
3. Do Not Pay the Ransom
Paying the ransom is highly discouraged for several reasons:
- No Guarantee: There’s no guarantee the attackers will provide the decryption key or that it will work.
- Encourages Further Attacks: Paying the ransom encourages cybercriminals to continue their activities.
- Double Extortion: Even after paying, the attackers might still publish stolen data or demand additional ransoms.
How our Ransomware Data Recovery Works
When ransomware encrypts your data, our professional ransomware data recovery services use a combination of decryption, data recovery, and forensic tools to restore access to your files. The recovery process typically includes the following steps:
1. Initial Assessment and Ransomware Identification
The first step in ransomware recovery is a thorough analysis of the infected system. This includes identifying the ransomware strain, determining how the attack occurred, and evaluating the extent of the encryption.
2. Removal of the Ransomware
Before any recovery attempts are made, the malware must be completely removed to prevent further encryption or system damage. This is typically done using advanced anti-malware tools.
3. Data Decryption or Recovery
If a decryption tool for the specific ransomware strain is available, it can be used to decrypt the files. If no decryption tool exists, we offer techniques such as our database with decryption keys, restoring data from backups, using brute force techniques, shadow copies, unencrypted portions of the files.
4. Data Reconstruction
In some cases, even if the files cannot be fully decrypted, forensic techniques and specialised tools may allow partial recovery of the encrypted data. Our Forensic Engineers use advance software to reconstruct damaged or corrupted files from available system snapshots or backups.
5. System Restoration and Hardening
Once the data is recovered, the system is restored to a safe state. The recovery service may also provide advice on how to strengthen security to prevent future ransomware attacks, such as updating software, applying security patches, and improving backup strategies.
How do I know if my system has Ransomware?
If you are infected with Ransomware such as Locky, CryptXXX etc you will experience some or all of the following in your computer or server:
1. Files have been renamed (or have new extensions added).
2. message on your computer screen advising you that your data has been encrypted and that you need to pay a ransom.
3. Files won’t open.
4. Files have been renamed (or have new extensions added).
5. Applications won’t open.
6. Antivirus software is disabled.
7. Computer system locked down.
What Not To Do If You Get Infected With Ransomware
If you become infected with Locky, CryptoWall, CryptXXX, or any other type of Ransomware malware, we advise that you perform an immediate shutdown of your computer or server. Do not remove the Ransomware software manually. Do not remove the Ransomware software by running a malware or anti-virus removal program.
