Losers Ransomware
Posted: October 27, 2017
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 Losers Ransomware is a Trojan that tries to block its victims from opening their files, including formats like documents or images. The symptoms of its attacks usually include delivering a ransom message that may ask you to pay money to restore the media that it's locking. If it's at all possible, victims should use free data recovery solutions to remedy this attack after deleting the Losers Ransomware with proper security software.
Trojans Picking Winners and Losers Among Your Files
One of the less notable families of file-locking threats may be continuing to update itself to spite working data recovery solutions as provided by the cybersecurity industry. The Losers Ransomware, a new Trojan using encryption to keep users from their media, is distributing itself with attacks highly similar to those of the Crypton Ransomware collective, whose last member, the Cry36 Ransomware, was verifiable months ago. As usual, the Losers Ransomware infections can damage content permanently and try to extort money by soliciting their victims.
While malware researchers can't yet confirm whether or not the Losers Ransomware is using a traditional enciphering mechanism like the AES-128, its payload does include a feature for encoding individual files. Media formats more likely than not of being targets are Word or PDF documents, Excel spreadsheets, JPG or GIF pictures, and compressed archives like RAR or ZIP. The Losers Ransomware also adds the '.losers' extension to the names of the locked media, which is a change from previous Crypton Ransomware Trojans.
Once it blocks the data, the Losers Ransomware contacts a C&C server and downloads a Notepad file, instead of generating one internally. This file contains the ransoming instructions for the victims to read, informing them of how to unlock their content by paying the threat actor. For the time being, malware researchers have limited information on the Losers Ransomware's ransom demands, but most Trojans use cash transaction methods that protect them from any risk of refunds, allowing them to disengage without needing to unlock anything necessarily.
The Fast Track to Victory over Losing Trojan Families
As a likely update to a family of Trojans well-known for rotating their encryption algorithms, the Losers Ransomware may be able to lock files without any previous decryption tools being capable of restoring them. PC users with any media they rate as worthy of preservation should back it up to a secure location, such as a cloud server, to eliminate decryption as the only way of retrieving their data. Although most the Losers Ransomware infections will inflict their file damage without any initial showing of symptoms, afterward, the Losers Ransomware also may cause issues, such as hijacking the user's wallpaper or blocking the desktop with a pop-up alert.
Some of the installation exploits that may be active for the Losers Ransomware include:
- Spam e-mails may attach installers for the Losers Ransomware, which can disguise themselves as ordinary documents, most often themed after workplace content or generic notifications.
- Corrupted websites may try to distribute the Losers Ransomware through exploit kits, a series of threats that scan for browser-related vulnerabilities automatically.
- Threat actors who gain login credentials also may use RDP features to drop the Losers Ransomware manually onto business, NGO or government servers.
Other than the caveat of the importance of using secure login combinations, all of these distribution exploits are defensible with appropriate security software, and users always should have an anti-malware program available for removing the Losers Ransomware.
Even though the book on the Crypton Ransomware family may seem complete, occasional upgrades like the Losers Ransomware show that its threat actors have more to add to the story. Unfortunately, this entry likely heralds another change in file-locking behavior that only is to the detriment of the victimized.
