Threat Metric

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

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.

Threat Level:	8/10
Infected PCs:	47

The Dr. Fucker Ransomware is a Trojan that demands ransom payments for providing help with undoing the damage its payload causes, which encrypts file data. Protecting and updating your backups can give you easy recovery options that avoid the risks of capitulating to the Dr. Fucker Ransomware's ransom demands. Conventional anti-malware products can play roles in preventing an infection and removing the Dr. Fucker Ransomware after an attack, although decrypting any files requires specialty software.

Trojans often use ironic or tongue-in-cheek themes that, on a first glance, may seem highly inappropriate to the attack in question. As an example of that demeaning sense of humor, the Dr. Fucker Ransomware offers easy, highly visible flags for identifying its attacks for sufficiently detached victims. Its symptoms include file-renaming extensions contrasting with extortion messages that malware experts have seen, in minor variants, in other file-encrypting Trojan campaigns.

Wild samples of the Dr. Fucker Ransomware first became available early in October, implicating Russia and neighboring countries as being the intended targets of its attacks. Although it has broader distribution numbers than, for example, the ISHTAR Ransomware, its payload is very similar. The Trojan leverages an AES encryption algorithm to encode your content, such as documents, and then protects the corresponding keys with a second, RSA algorithm. It also adds its personal extension ('.iloveworld').

Along with the recognizable nature of its file tag, the Dr. Fucker Ransomware also sets itself apart from similar threats by its use of an in-depth Web infrastructure. Malware analysts can confirm at least one threat actor acting as 'technical support' through the website the Dr. Fucker Ransomware's ransom messages promote as payment processors. In spite of this on-hands touch, multiple victims are experiencing issues with acquiring a decryptor after paying.

The Dr. Fucker Ransomware also pressures its victims with an embedded HTML timer meant to hasten the payment process. However, malware analysts find no functions in the Dr. Fucker Ransomware correlating to the timer's expiration (although its threat actors may take further actions, such as deleting any decryption data that they possess).

The Dr. Fucker Ransomware is in live distribution under multiple names, including castarimon.exe and barbinor2.exe, with Russians and Eastern Europeans being at particularly high risk. Since the Dr. Fucker Ransomware suppresses any error windows generated by Windows during its installation and uses hooks for its presence in memory, PC users are unlikely to detect an attack until after the encryption of their data. Free decryption tools are not yet up for download for the Dr. Fucker Ransomware, and, as with the other AES/RSA-encrypting threats malware experts are examining, may never be available.

Running anti-malware scans on files you download before opening them and removing potentially hazardous browser options (such as default JavaScript or Flash loading) can stop many of the exploits in use by threats of this category. Since the Dr. Fucker Ransomware uses flexible extortion demands most often seen in deployment against for-profit entities, vulnerable businesses may wish to pay particular attention to any network-accessible content or servers that this threat could attack.

Even when most, seasoned anti-malware products should experience few problems with removing the Dr. Fucker Ransomware, reversing all the damages it causes is another matter. Forethought in PC security always is cheaper than paying a Trojan 'doctor' down the road.
