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:	13

First Seen:	July 10, 2024
OS(es) Affected:	Windows

The Annabelle Ransomware is a variant of the FTSCoder, a Trojan that can lock your files with encryption, display threatening messages and cause other system errors. The Annabelle Ransomware update of this family is capable of blocking the user's access to the Windows software and features and can interfere with the startup routine particularly. Since this Trojan can cause permanent damage to either the operating system or any stored media, users should have their anti-malware tools delete the Annabelle Ransomware as a high-level threat whenever its presence is a possibility.

File-locking Trojans are known, mostly, for their ability to deprive the user of access to content like photos or documents by encrypting the files, using an attack not much different from the archiving features of apps like WinZipper technically. However, the FTSCoder or Stupid Ransomware family of these threats is offering a supporting array of hostile functions that can endanger the entire operating system, as well as any private, saved media. The newest member, the Annabelle Ransomware, bears a strong resemblance to the Jigsaw Ransomware but is possibly even more disruptive than that old threat.

Like most threats of its kind, the Annabelle Ransomware uses encryption to disable different formats of files, such as RTF documents or JPG pictures, and also adds an extension ('.ANNABELLE') to their names. Some of the more unusual aspects of the Annabelle Ransomware's payload that malware researchers are pointing out include:

The Annabelle Ransomware reboots Windows and replaces the 'Userinit' configuration automatically so that it can force the OS to boot to its ransom note directly.
The ransoming message is an HTA pop-up window that's very similar to that of the Jigsaw Ransomware's warning and includes instructions on accessing the TOR website and paying a 0.1 Bitcoin ransom for decrypting your files, as well as supporting features, like a countdown element.
Once its timer hits zero, the Annabelle Ransomware sabotages the MBR, causing the PC to boot to a second error screen directly without loading the operating system.
Even before this time limit's expiration, the Annabelle Ransomware blocks other applications using IFEO exploits, including Notepad, different Web browsers and the Registry Editor.

The Annabelle Ransomware's message window also includes some elements of social engineering by employing intimidating imagery referencing 'Annabelle,' the doll-themed horror film.

Although this Trojan's threat actor, 'iCoreX0812,' recommends paying the Bitcoin ransom for unlocking your files and disabling the Annabelle Ransomware, malware analysts often find versions of this family as being compatible with free decryption programs. However, promptly disabling the Annabelle Ransomware is critical for re-securing access to a variety of security features and Windows programs. Since this threat also operates in Safe Mode, users should employ other security protocols, as appropriate, such as booting directly from a recovery-based USB.

Back up your files to keep them from suffering any damage that you can't revert, such as non-consensual encryption. Some in-development versions of the Annabelle Ransomware may generate .NET Framework alerts during the initial installation routines, but any users without additional protection against threatening software can't interrupt its payload. Malware experts strongly advise keeping anti-malware software open and updated for catching and removing the Annabelle Ransomware, along with the other members of the Stupid Ransomware family.

The Annabelle Ransomware is a new version of a black hat software project that's gone through psychologically manipulative themes of various types, as readers can see via the BlackSheep Ransomware, the Cyron Ransomware, the Eternity Ransomware or the Haters Ransomware. In every case, the threatening nature of a pop-up only obscures the greatest danger, which lies in the security-disabling functions of the program that's running 'behind the screen.'
