There are different methods to help victims identify ransomware types that have infected their machines. This includes their characteristics, such as file extensions and ransom notes left behind by attackers.
Also, ransomware identification tools can help users quickly identify ransomware variants, free and fast.
Ransomware is a malicious software that encrypts or locks files, making them inaccessible until a ransom is paid. It has become increasingly prevalent in recent years and can cause serious damage to individuals and organizations alike. To decrypt ransomware-encrypted files, you must first identify the ransomware type.
There are certain characteristics and methods you can use to help identify which ransomware variant may have infiltrated your device.

5 ways to identify ransomware type
Understanding the different methods for identifying ransomware variants that have infiltrated your system will better equip you to take appropriate steps for removal or mitigation.
🔍 5 Methods to Identify Ransomware Type
Use ID Tools
Upload ransom notes or encrypted files to free tools like ID Ransomware for instant variant identification.
Check Ransom Note
Examine the ransom note for unique identifiers, contact methods, and payment instructions specific to each variant.
File Extensions
Look at encrypted file extensions (.lockbit, .alphv, .akira, etc.) to narrow down the ransomware family.
Technical Analysis
IT professionals can examine coding patterns, strings, and malware behavior for precise identification.
Behavioral Signs
Analyze specific behaviors like shadow copy deletion, data exfiltration, or security software disabling.
Remember to preserve evidence of the attack, such as the ransom note and encrypted files, for the forensics report.
1. Use a Ransomware ID tool for a quick scan
The ID Ransomware tool is an easy-to-use, open-source solution that can help users quickly identify the ransomware type they’re dealing with.
Proven Data experts created a free ransomware identification tool to help victims identify the type of ransomware on their machines. After identifying the ransomware variant, you can immediately request help.

2. Look for a ransom note
Attackers will often leave a ransom note with instructions on how to pay the ransom. Recent ransomware groups also threaten to leak stolen data if the victims do not pay the ransom. This tactic is known as double extortion.
Additionally, the ransom note may contain the attackers’ contact information, such as an email address or web page. This can help identify ransomware variant types.
3. Check the file extension
Many ransomware variants use a unique file extension to encrypt files. By looking at which one is used, you can narrow down the list of potential ransomware types.
Common ransomware file extensions include .lockbit, .alphv, .akira, .cactus, and hundreds of others. Take note of the exact extension since it’s one of the quickest ways to narrow down the variant. Some ransomware adds random extensions, making ID tools even more necessary.
4. Get technical with identification methods
You may need to resort to more technical methods of identification, such as examining the coding style or certain strings left in the malware. An IT professional or ransomware recovery expert can identify the ransomware family.
Professional ransomware recovery services are also ideal for assisting with identification, as they are usually 24/7 and can identify and remove ransomware with the least risk to your data.
5. Analyze the behavior of ransomware
Most ransomware variants display certain behaviors that can be used to identify them, such as deleting system files or shadow copies, exfiltrating data, or disabling security software and firewalls.
Locker Ransomware vs Crypto Ransomware
In addition to identifying the specific type of ransomware, it is also important to know the difference between locker ransomware and crypto-ransomware. Understanding ransomware encryption methods helps determine recovery options.
Differentiating between locker ransomware and crypto-ransomware can help you decide how best to respond to protect your data.
📊 Locker vs Crypto Ransomware: Key Differences
| Feature | Locker Ransomware | Crypto Ransomware |
|---|---|---|
| Encrypts Files | ✓ Yes | ✓ Yes |
| Blocks System Access | ✓ Yes | ✗ No |
| Disables Keyboard/Mouse | ✓ Yes | ✗ No |
| Threatens File Deletion | ✗ Rare | ✓ Common |
| Can View Files (Locked) | ✗ No | ✓ Yes |
| Data Exfiltration | ✗ Less Common | ✓ Common (Double Extortion) |
| Recovery Difficulty | Easier | More Challenging |
Locker ransomware encrypts files and prevents users from accessing them until a ransom is paid. It also blocks basic computer functions, like disabling the keyboard and mouse. This type of ransomware usually doesn’t destroy your files; it only locks you out of the system until you pay the ransom demand.
Crypto ransomware, on the other hand, usually encrypts files as well but also threatens to delete them if payment is not made within a certain amount of time. However, it doesn’t block basic computer functions, but it locks every file on it. This means you can still use your computer and see your files without being able to open them.
Keep in mind that most ransomware gangs encrypt and lock files and exfiltrate sensitive and critical data. This tactic, known as double extortion, threatens to delete the files and leak the data on a Tor website if the victim does not pay the ransom.
Did you suffer a ransomware attack?
If you are a victim of a cyberattack, contact 24/7 ransomware and breach response services immediately to salvage your encrypted data. Proven Data experts can restore your data and help you through the steps after a ransomware attack.
Contacting professionals and following your Incident Response Plan will always be your top priority during an emergency. That said, these are the first actions to follow that will mitigate damage and increase the chances of a full recovery:
🚨 Immediate Actions After Ransomware Identification
Disconnect from Network
Immediately isolate infected devices to prevent spread to other systems
Do Not Pay the Ransom
Payments offer no guarantee of file recovery, and they fund criminal operations
Preserve Evidence
Save ransom notes, encrypted file samples, and system logs for forensic analysis
Check for Decryptors
Visit NoMoreRansom.org to see if free decryption tools exist for your ransomware variant
Contact Recovery Experts
Professional ransomware recovery services can often restore data without paying
Report the Attack
Notify law enforcement (FBI IC3) and relevant authorities for investigation
Remember, prevention is always the best tactic against ransomware. By staying one step ahead of attackers and identifying different ransomware types, you can reduce the risk of a successful cyberattack on your system. Implement strong ransomware prevention strategies to protect your data.
