Rapid 2.0 ransomware removal instructions

What is Rapid 2.0?

First discovered by MalwareHunterTeam, Rapid 2.0 is an updated version of high-risk ransomware called Rapid. Immediately after infiltration, Rapid 2.0 encrypts most stored files and renames them using the "[7_random_digits].[5_random_letters]" pattern. For example, "1.jpg" might be renamed to a filename such as "1390875.HWCLZ". From this point, using and distinguishing files becomes impossible. Once files are encrypted, Rapid 2.0 creates a text file ("DECRYPT.[5_random_letters].txt") and places a copy in every existing folder.

There are two main differences between Rapid 2.0 and its previous version. Firstly, the original version did not rename files - it was designed to append filenames with the ".Rapid" extension. Secondly, Rapid 2.0 detects the system's locale. If the locale is set to Russian, files are not encrypted. The new text file contains a message informing victims of the encryption and telling them what to do next. The message simply states that files can only be decrypted using a specific decryption tool that must be purchased. Unfortunately, this is accurate. It is currently unknown which cryptography (symmetric or asymmetric) Rapid 2.0 uses, however, decryption will certainly require a key generated uniquely for each victim. Criminals hide these keys on a remote server and victims are encouraged to pay a ransom in exchange for a decryption tool with the key embedded within. The cost is not specified - victims must contact Rapid 2.0's developers to receive further instructions, however, in most cases, the size of ransoms fluctuates between $500 and $1500 (equivalent in Bitcoins or another cryptocurrency). Criminals also allow victims to attach one selected file, which can then be decrypted and returned to the victim as a 'guarantee' that decryption is possible. Despite these demands and threats, cyber criminals can never be trusted, since they often ignore victims, once payments are submitted. Paying typically gives no positive result and victims are simply scammed. Therefore, never attempt to contact these people and certainly do not submit any payments. Unfortunately, there are no tools capable of decryption of files compromised by Rapid 2.0. The only solution is to restore everything from a backup.

There are dozens of ransomware-type viruses similar to Rapid 2.0. The list of examples includes (but is not limited to) BlackRuby2, Zenis, PLANETARY, and GPGQwerty. Although these viruses are developed by different cyber criminals, they have identical behavior - they encrypt data and make ransom demands. Research shows that, in most cases, ransomware-type viruses have just two major differences: 1) cost of decryption, and; 2) type of encryption algorithm used. Unfortunately, most use algorithms that generate unique decryption keys (e.g., RSA, AES, and so on). Therefore, unless the malware is not fully developed or has certain bugs/flaws (e.g., the key is hard-coded, stored-locally, etc.), restoring files without involvement of developers (contacting these people is not recommended) is impossible. Rapid 2.0 and other similar viruses are one of the main reasons for maintaining regular data backups, however, backup files must be stored on a remote server or an unplugged external storage. If not, backups are encrypted together with regular files.

How did ransomware infect my computer?

To proliferate ransomware, developers often use spam emails, peer-to-peer (P2P) networks, third party software download sources, fake software update tools, and trojans. Spam emails often contain malicious attachments (e.g., JavaScript files, MS Office documents, etc.) that, once opened, stealthily download and install ransomware, whilst P2P networks (torrents, eMule, etc.) and other unofficial download sources (free file hosting websites, freeware download websites, and so on) proliferate malware by presenting it as legitimate software. Users are tricked into downloading and installing viruses. Fake updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than software updates. Trojans are the simplest ones - they open "backdoors" for other high-risk malware to infiltrate the system. Essentially, the main reasons for computer infections are poor knowledge and careless behavior.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, pay close attention when browsing the Internet. Never open any email attachments that seem irrelevant and have been sent from unrecognizable/suspicious email addresses. In fact, these emails should be deleted without reading. Remember also to download your applications from official sources only, using direct download links. Third party downloaders/installers are often used to proliferate rogue apps, and therefore, these tools should never be used. Keep installed applications up-to-date and have a legitimate anti-virus/anti-spyware suite installed and running, however, since criminals proliferate malware using fake updaters, applications should be updated using implemented functions or tools provided by the official developer only.
