BTC ransomware – another menace in the cyber space

The first signs of BTC or alternatively called BTCLocker were detected already on the last months of 2016. Specialists suspect it to be the derivative version of Radamant virus. On the other hand, it also leads to another file-encrypting malware called CryptoMix. It already gave birth to a dozen new malware. The acronym of the malware supposedly stands for bitcoin. Such name was also given due to another feature of the malware – after infiltrating the system, the malware appends .BTC file extension to encrypted documents. Further information on data recovery is presented in BTC_DECRYPT_FILES.txt or IDR__BTC_DECRYPT_FILES.txt. BTC ransomware authors do not miss the opportunity to alarm victims – the payment should be transmitted during the indicated period. It seems that the hackers are not apt in using Tor network and contact in more sophisticated ways. In the case of inquiry, victims should contact zikr@protonmail.com, zikra@protonmail.com, or zikr@usa.com. According to the reports, the felons of this malware are not inclined in returning the files after you pay. On the contrary, after you make the transaction, you will be demanded to pay an additional amount of money. Direct your attention to BTC removal. Reimage or Malwarebytes Anti Malware is one of the options to terminate the infection.

For some users, 0,5 (≈£500) or 1,5(≈£1300) bitcoins might seem like a sufficient sum of money to pay in order to retrieve the files. One of the most problematic issues when dealing with a file-encrypting threat is that you cannot rely on fraudsters’ sense of conscience. In the case of BTC malware, the authors seem to be even keener on breaking their word. We do not recommend downloading BTC Decrypter proposed by the cyber villains. Amid the hopes of returning the data, you might install a ‘long-term malware’ which get activated after some time. Such software is also speculated to have spyware elements. Instead, hurry up to remove BTC malware. On the other hand, less delicate malware might be prevented if you restart the system. Even if BTC modifies startup files, restart the device. This action might interfere with the encryption process. Other versions of the infections might trigger fake User Account Control messages. Do not rush to enable them. Hackers might forge the name of initiating the program and present it as a Microsoft Windows process. However, unexpectedly long file names or odd system locations might signal you of the malice. During the encryption, the device starts to underperform. Check whether no questionable tasks are activated in Task Manager.

Does this malware spread in any peculiar ways?

BTC virus does not stand out much considering its distribution techniques. In fact, you are most likely to get infected with it via a spam message. Unfortunately, users are still not aware of possible consequences after curiously opening unknown attachments. Later on, they might have to battle not only an elaborate virus but look for data decryption alternatives. In addition, ransomware might be disguised as an exploit kit. In order to improve the protection from such virtual menaces, you need to add an anti-spyware application to the current anti-virus program. On the final note, if your browser toolbar is loaded with a series of extensions and plug-ins, note that crypto-malware might take its disguise as well. Such cautiousness will reduce the probability of encountering BTC hijack.

Are there any guarantees that BTC ransomware is fully eliminated?

BTC removal may not be a highly difficult task. Entrust the elimination process to malware removal software. In case, you cannot launch it, you might find the below-displayed guide to be of use. At the very bottom of the page, there is a few suggestions on data recovery as well. Luckily, this malware seems to belong to the group of decryptable crypto-malware. Until then, you might restore your files either via backups or shadow volume copies. More information about the latter method is provided under ‘Bonus’ recovery headlines.
