ETH ransomware removal instructions
What is ETH?
First discovered by malware security researcher, Jakub Kroustek, ETH is a new variant of a high-risk ransomware infection called Dharma. After successful infiltration, ETH encrypts most stored files and appends filenames with the ".ETH" extension plus the developer's email address and victim's ID. For example, "sample.jpg" might be renamed to "sample.jpg.id-1E857D00.[email@example.com].ETH". Once data is encrypted, ETH generates a text file ("FILES ENCRYPTED.txt"), which is placed on the desktop, and opens a pop-up window.
The text file and pop-up window contain similar messages stating that data is encrypted and that victims must contact ETH's developers if they want to restore it. It is also stated that victims must purchase a decryption tool/key to restore encrypted data. It is currently unknown which type of cryptography (symmetric or asymmetric) ETH uses, however, decryption requires a unique key generated individually for each victim. Developers hide all keys on a remote server and so, to receive their decryption keys (together with decryption tools), victims must pay a ransom. The cost is not specified and supposedly depends on how quickly victims make contact with these cyber criminals. Detailed payment information is provided via email, however, in most cases, the size of ransom fluctuates between $500 and $1500 in Bitcoins or another cryptocurrency. Regardless of the cost, do not pay. Research shows that cyber criminals often ignore victims once payments are submitted. Therefore, paying typically gives no positive result and users are scammed. Therefore, we advise you never to contact these people and certainly do not send any money. There are currently no tools capable of cracking ETH encryption and restoring data free of charge. You can only restore everything from a backup.

The internet is full of ransomware-type viruses that share similarities with ETH (e.g., UNIT09, LockerGoga, ITLOCK, Cyspt, etc.). As with ETH, these viruses also encrypt data and make ransom demands. Ransomware-type viruses might differ in two ways: type of encryption algorithm used and size of ransom. Unfortunately, most use cryptographies that generate unique decryption keys (e.g., RSA, AES, and similar). Therefore, decryption without developers' involvement is mostly impossible. The only possible scenarios are ransomware not being fully developed or having certain bugs/flaws (e.g., the key is stored locally, is hard-coded, or similar). Viruses such as ETH present a strong case for maintaining regular data backups, however, store them on remote servers (e.g., Cloud) or unplugged storage devices (e.g., external hard drive, Flash drive). If not, backups are encrypted together with regular data.
How did ransomware infect my computer?
It is currently not known exactly how cyber criminals proliferate ETH, however, ransomware developers typically use the following methods: trojans, software cracking tools, fake updaters, third party download sources, and spam email campaigns. Trojans are viruses that, once infiltrated, cause "chain infections" - they stealthily download and install other malware into the system. Software cracks are used to activate paid software without paying, however, cyber criminals often use them to proliferate malware, rather than activating software. In this way, users often infect their computers. Fake updaters infiltrate malware by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. Third party download sources (peer-to-peer networks, free file hosting sites, freeware download websites, etc.) are used to present malware as legitimate software. Users are simply tricked into downloading and installing viruses. Similar rules apply to spam campaigns. Criminals send hundreds of thousands of emails with deceptive messages encouraging users to open attachments (links or files), which are often presented as bills, invoices, or other important documents. Opening them results in a malware infection.

|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All 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.|
To eliminate ETH virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the internet and downloading, installing and updating software. Carefully analyze each email attachment received. Files/links that are irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. You are also advised to download software from official sources only, using direct download links. Third party downloaders/installers often include rogue applications, and thus these tools should never be used. Keep installed applications and operating systems updated, however, to achieve this, use implemented functions or tools provided by the official developers. Furthermore, never use software cracking tools, since using pirated software is considered a cyber crime and you also risk infecting your computer. Have a legitimate anti-virus/anti-spyware suite installed and running at all times - this software can detect and eliminate malware before it does any harm. If your computer is already infected with ETH, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
