Comrade Circle Ransomware
Posted: October 10, 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 Comrade Circle Ransomware is a Trojan with file-encoding features that block your content to force you into paying a fee for the restoration process (also known as decryption). Paying for your data's recovery may provide no real solution, and malware experts advise using preemptive data and system protection, when applicable. Current anti-malware security should detect and remove the Comrade Circle Ransomware before it can finish encrypting any content.
Completing the Circle of Misdeed by Including Its Victims
Con artists using threat-based encryption attacks often try to profit from one of two business strategies: taking ransoms from any victimized individuals or taking money from other con artists with less programming knowledge for the privilege of being allowed to use the file encryption program. The Comrade Circle Ransomware's authors have taken the unusual step of trying to merge the two models together, potentially causing a victim to become an affiliate and, in turn, a fellow distributor of file encrypting Trojans.
Malware analysts estimate that the Comrade Circle Ransomware's installers are spam-distributed, comprising of such exploits as fake LinkedIn notifications, disguised attachments and similar e-mail content. When it gains system access, the Comrade Circle Ransomware triggers a fake 'Windows update' screen to hide that the Trojan is encrypting your data. Once the screen completes, your files will be renamed and encoded with an AES algorithm. Unlike most Trojans with the same designs, malware experts saw the Comrade Circle Ransomware overwriting the original names in full and replacing them with base64 strings in addition to adding custom extensions.
The Comrade Circle Ransomware's most significant feature is its ransom message, which asks for money in exchange for restoring your content. Some paragraphs in these instructions provide additional information on the Comrade Circle's supposedly charitable motives, as well as encouraging victims who are too poor to pay a ransom to help distribute the Trojan out of a promise of future riches. Malware experts can't corroborate the Trojan's claims of providing revenue to these opt-in affiliate victims, which most likely is a tactic meant to increase the scope of the campaign without any extra effort on the part of the original authors.
Breaking the Cycle of Trojan Attacks
Although the Comrade Circle Ransomware's code is most likely derivative from past threats, particularly the Fantom Ransomware, its social engineering strategy is a creative one that could pay off by giving the threat unpredictable new ways of installing itself. For those interested in recovering content that has been enciphered by the Comrade Circle Ransomware, malware researchers recommend using methods not associated with paying con artists for potentially fictitious or malfunctioning decryptors, which always is less dependable than restoring from backups.
You can see successful Comrade Circle Ransomware infections by identifying their fake update screens, their 'RESTORE-FILES!
As usual, the promise of riches by Trojans like the Comrade Circle Ransomware is more of an optimistic prophecy for its authors than a sign of help for any of its victims. Whether or not you have any way of restoring your data without paying its extortion fee, abetting a threat campaign casually, is an act unlikely of reaping any reward.
