The Bitcoinrush Ransomware is a file encryptor that encodes your data that it isolates by specific formats with the expectation that its victims will pay a Bitcoin ransom to get their information restored. Symptoms of the Bitcoinrush Ransomware being confirmed by malware analysts include changes to the desktop wallpaper, as well as to file names and sizes. You should not pay the ransom, and removing the Bitcoinrush Ransomware with anti-malware protocols followed by enacting other data retrieval steps is the recommended recovery strategy.

The Continuing Rush to Filling Bitcoin Accounts

The Bitcoinrush Ransomware is a recent file encryptor using both the aesthetic components and general tactics of previous campaigns for the purpose of soliciting Bitcoin funds from random PC owners. Examples of threats similar to the Bitcoinrush Ransomware include the Ecovector Ransomware, the Vegclass@aol.com Ransomware and the Centurion_Legion Ransomware, although malware experts have yet to verify a direct coding relationship. Similarly to these past campaigns, the Bitcoinrush Ransomware's predominant symptom is the alteration of your files by including new file names, with ID numbers custom to the attack, the '.xtbl' extension and an e-mail address.

The e-mail address provided is for contacting the con artists soliciting a ransom, which the Bitcoinrush Ransomware provides motivation for by encrypting the data it renames. Malware experts have seen some evidence of the Bitcoinrush Ransomware using an encryption technique that divides files into two components, necessitating that both halves be present for fully recovering the internal data. Current free decryptors for the families associated with similar attacks (the Rakhni and HydraCrypt Ransomware) are ineffective at achieving recovery reportedly.

Victims should note that, despite its perpetrators most likely taking ransoms exclusively in the Bitcoin currency, the Bitcoinrush Ransomware is not affiliated with the Bitcoin Rush gambling site.

Who to Call to Get Out of an E-mail Ransom Request

While a desktop change to a ransoming demand and the equally obvious changes to your file names are very evident symptoms of a Bitcoinrush Ransomware infection, this threat's installation methods have yet to be confirmed. Threats most similar to the Bitcoinrush Ransomware used exploit kits and other techniques rooted in drive-by-download strategies or e-mail attacks previously. For protecting yourself from the first infection method, malware experts recommend updating software and using live Web-surfing security. You may identify e-mail attachments under any degree of suspicion as potential the Bitcoinrush Ransomware carriers by using your anti-malware products to scan them before opening.

The payload of a Bitcoinrush Ransomware attack has few divergences from the payloads of past Trojans of its classification. However, its innovations in data encoding techniques may prevent security companies from providing free methods of restoring your PC's data temporarily. You should back up difficult-to-replace content to locations malware experts rate as being less at risk of compromise, such as detachable USB drives.

Renaming your files has no impact on the encryption attack the Bitcoinrush Ransomware uses, and malware experts discourage doing so, which may make it difficult to identify the affected content. No matter how you choose to deal with the effects of an infection, always giving your anti-malware products the opportunity to remove the Bitcoinrush Ransomware will provide the maximum assurance of no future encryption-based attacks.

For all of its few differences from other threats, the Bitcoinrush Ransomware does show that even the smallest of internal updates can make old threats a new problem for the PC security sector.
