KeyBTC Ransomware
Posted: May 2, 2016
Threat Metric
The following fields listed on the Threat Meter containing a specific value, are explained in detail below:
Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.
Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

The KeyBTC Ransomware is a threatening file encryptor that modifies the internal code of your files and then sells a reversal of the modification, or a decryptor, back to you. Although the KeyBTC Ransomware's authors claim that they will provide a demonstration of their decryption service, most PC users should consider using free means of data recovery that don't require paying a ransom. Always try to identify and then remove the KeyBTC Ransomware with an anti-malware product once you see its characteristic symptoms.
The Key to Your Files that's Split in Two
The KeyBTC Ransomware is a Trojan that uses social engineering tactics, such as putting its ransom payments on a timer and providing misleading recovery information, to guarantee that its victims make their payments. Although the technical implementation of its ransom and decryption process includes some unusual decisions, the bulk of its features is similar to those of older file encryptors. As usual, the victim of a KeyBTC Ransomware infection can depend on changed file names and ransom messages extremely visible delivered in text and image formats to identify this threat.
The KeyBTC Ransomware installs itself through ZIP-compressed e-mail attachments that use JavaScript, although their names imply falsely that they're Word documents. The KeyBTC Ransomware's payload, triggering automatically after its installation, includes encrypting and renaming files of non-essential types, such as Microsoft Office formats. They also are given new extensions referencing the KeyBTC Ransomware's current e-mail address, which it uses for its ransom and decryption transactions.
Most file encryptors under analysis by malware experts store their decryption information in a single file, which the threat uploads to a remote server. The KeyBTC Ransomware uses a slightly unusual methodology of storing the relevant decryption data in two local files that are, in turn, encrypted with a second algorithm. Victims can then transfer them (file1.bin and file2.bin) to the con artists, along with a single file, before they receive any further details about how to make the KeyBTC Ransomware's ransom payment and restore all data.
Unlocking Your Hard Drive's Contents without Buying a Black Market Key
The KeyBTC Ransomware claims that no alternative means are available for decrypting your data, but, as usual for such threats, offers incorrect information while backing up this assertion. Although the KeyBTC Ransomware does delete local backup data, malware researchers still can encourage restoring your content through a non-local backup, such as a cloud storage service. Some PC security institutions also provide free decryption utilities for unlocking files encrypted by threatening file encryptors.
Most, if not necessarily all encryption Trojans use well-known installation exploits that centralize around e-mail spam. Be cautious about e-mail attachments from unconfirmed senders, including documents that may contain macro-based vulnerabilities for installing the KeyBTC Ransomware. A scan by any up-to-date anti-malware product should be able to identify most Trojan droppers responsible for placing these threats, which will prevent you from needing to worry about data recovery at all. If the installation does succeed, such tools also should be used for removing the KeyBTC Ransomware, which conceals its processes and files.
The urgent pressure the KeyBTC Ransomware places on those attacked by it can be contrasts starkly with the duplicitous nature of the facts provided in its recommendations. Malware experts almost always can suggest viable solutions for restoring a hard drive's contents without calling for making any payments to the people responsible for the original infection.
