Amnesia Ransomware
Posted: May 2, 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 Amnesia Ransomware is a file-encryption Trojan, which blocks files on your computer, usually to ask for money for the customized unlocking key or service. Although this Trojan exhibits symptoms traditional for the Globe Ransomware, malware experts can confirm that the Amnesia Ransomware isn't a member of this family, which may impede any free decryption solutions. Its distribution methods are unknown, but you can use standard anti-malware products and features for removing the Amnesia Ransomware before it can encrypt any files.
Trojans Reminding Us not to Forget Basic Backup Practices
Due to no culpability of their own, most PC users don't indulge in tracking which families of threatening software are current or outdated. Nonetheless, this ignorance can help threat actors disguise their products or promote themselves by misappropriating the brands of other campaigns. In cases like the newest file-encrypting Trojan, the Amnesia Ransomware, a mistaken identity can even be an obstacle in the disinfection and recovery process.
The Amnesia Ransomware's author built this Trojan with the somewhat unusual choice of the Delphi programming language, similar to the Telecrypt Ransomware. Current file names for the Amnesia Ransomware's executable imply that the Trojan is circulating as a fake 'guide' document, spreadsheet or slideshow. The Amnesia Ransomware also employs some anti-virtual environment features to limit analysis in a research environment.
Otherwise, the Amnesia Ransomware includes many of the traditional implementations of a modern, file-encrypting threat. A mutex prevents the Trojan from installing and running multiple instances of itself, and Registry modifications guarantee its automatic launching with no user-interface to see. Its attacks include encrypting files, such as documents, with a cipher to keep them from opening, as well as creating a Notepad message with ransoming instructions and the system's unique ID number.
Meaningfully, although the Amnesia Ransomware's most visible element, its ransoming message, is identical to that of the Globe Ransomware family, the Amnesia Ransomware uses a different encryption routine and isn't a direct relative of the old group of threats.
Feeling Free to Forget the Latest Trojan Craftsmanship
If used improperly, decryption methods that work against the Globe Ransomware could not only fail but even damage your blocked files further, making them impossible to decode. Malware experts also are unable to acquire current data on the Amnesia Ransomware's ransom payment details but recommend against availing yourself of any decryption method that involves funding illicit enterprises or using non-refundable services like Bitcoin. Providing samples of both the Amnesia Ransomware and the encrypted content to appropriate security researchers may provide valuable data for a potentially free decrypting solution.
The Amnesia Ransomware also still may be under development and shows no signs of the network activity that would correspond with its threat actor's possessing the appropriate decryption information for a victim's files currently. The omission of such details can lead to victims paying to get their files back and getting no data recovery, with no way to penalize the Amnesia Ransomware's administrator.
Commonplace anti-malware solutions may remove the Amnesia Ransomware preemptively and protect your media by stopping it from being encrypted. For anyone with inadequate anti-malware protection, having a recent, emergency backup still is a straightforward way of avoiding the fate of being unable to open what's already on your hard drive.
