SEED LOCKER Ransomware

Also Known As: SEED LOCKER virus
Distribution: Low
Damage level: Severe

SEED LOCKER ransomware removal instructions


This ransomware was discovered by Emmanuel_ADC-Soft. SEED LOCKER is a malicious program that belongs to the Everbe ransomware family. Like most ransomware-type programs, it is used to encrypt data (make it unusable) and make ransom demands. After encryption, files affected by this ransomware have a new, additional extension (".seed"). For example, a file named "1.jpg" is renamed by SEED LOCKER to "1.jpg.seed". The program also generates a ransom message within the "!#_How_to_decrypt_files_#!" text file.

In the ransom message, SEED LOCKER's developers state that this ransomware has encrypted all files, however, the encrypted data is modified and not damaged or corrupted. Cyber criminals claim that the only way to decrypt files is using a specific decryption program (tool). To obtain it, victims must contact the developers via the or email address and provide the assigned ID (a unique number). Note, however, that in most cases these tools are not free. In exchange for a decryption tool, ransomware developers demand payment of a specific sum in a cryptocurrency. It is likely that they will state the cost and provide the cryptocurrency wallet address when they are contacted. Before making the transaction, SEED LOCKER's victims are offered free decryption of up to three files as 'proof' that the developers can be trusted and have a tool capable of decryption. In fact, it is not safe to pay these people for the promised tool. Most cyber criminals ignore victims once they receive ransom payments. Therefore, do not contact SEED LOCKER's developers or make any transactions, otherwise you are likely to become the victim of a scam. Unfortunately, ransomware developers employ cryptography algorithms (symmetric or asymmetric) that make decryption impossible without using a specific tool (or key). Therefore, in most cases, only ransomware developers can provide decryption tools/keys. Typically, no other programs can perform a successful decryption. The best, free option for people who become victims of ransomware-type programs is to use a data backup that was created before encryption and restore everything from there.

SEED LOCKER decrypt instructions

Development of ransomware-type programs is now popular and there are many programs similar to SEED LOCKER including, for example, GANDCRAB 5.2, Cammora, and Heets. These malicious programs have two main goals: to encrypt data and to allow developers to blackmail victims by making ransom demands. Major differences are usually cost of decryption tool/key and cryptography algorithm used for encryption. Unfortunately, encryptions caused by ransomware cannot be decrypted free of charge (without the involvement of cyber criminals), unless the program is still in development, contains bugs/flaws, etc. Therefore, we recommend that you maintain regular backups and store them on remote servers or unplugged storage devices. Otherwise your files might be encrypted together with other data that is stored on the computer.

How did ransomware infect my computer?

It is not known exactly how SEED LOCKER's developers distribute this ransomware program, however, cyber criminals often use emails (spam campaigns). They send emails that contain malicious attachments such as Microsoft Office documents, JavaScript files, executables (.exe), PDFs, archives (ZIP, RAR, and other files), and so on. If opened, these attachments download and install ransomware (or other high-risk infections). Another way to proliferate ransomware-type programs is through untrustworthy software download sources. Some examples of dubious channels to download software are: freeware and free file hosting websites, Peer-to-Peer networks (torrent clients, eMule, and so on), third party software downloaders, and other similar tools. Cyber criminals present their malicious files as legitimate, however, by executing them, many people cause computer infections. Unofficial (fake) software updaters can also be used to distribute ransomware. These tools download and install malicious programs rather than the expected software updates or fixes. They might also be used to exploit bugs, flaws of outdated software. Software cracking tools operate in a similar manner. People use them to activate operating systems or software free of charge, however, these tools are often employed by cyber criminals to install malware. Computers are also infected through Trojans, malicious programs that proliferate other programs of this type (they cause chain infections). Note, however, that to be able to install malicious programs, a trojan must first be installed.

Threat Summary:
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.
Malware Removal (Windows)

How to protect yourself from ransomware infections?

To keep computers safe from these infections, be cautious when browsing the web, downloading, installing and updating software. Various links or attachments presented in emails received from unknown/suspicious addresses should never be opened or clicked. Software should be downloaded via official and trustworthy sources only, and not third party downloaders, unofficial sites, torrent clients, or other sources mentioned earlier. Keep installed software updated, however, this should be done using implemented functions or tools provided by official developers only. Paid software should not be activated using cracking tools. These are illegal (people who use them commit cyber crime) and are often the reason behind various computer infections. Have reputable anti-virus/anti-spyware software installed and keep it enabled at all times. Software of this type often detects malicious attacks and eliminates threats before it is too late. If your computer is already infected with SEED LOCKER, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the SEED LOCKER ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining SEED LOCKER ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of SEED LOCKER are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by SEED LOCKER, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as SEED LOCKER ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
