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:	2/10
Infected PCs:	60

First Seen:	September 26, 2024
OS(es) Affected:	Windows

The BaYuCheng@yeah.net Ransomware is a file-locking Trojan and a possible fork of the XiaoBa Ransomware. This threat uses encryption as a means of blocking different data kinds, such as images and documents, and also shows pop-ups associated with its ransoming negotiations. You can preserve your files from similar attacks by keeping secure backups of them and letting your anti-malware applications block and remove the BaYuCheng@yeah.net Ransomware.

A Fake Dharma Ransomware Arrives in Asia

Victims of file-locking attacks can suffer confusion from judging a Trojan by the symptoms that they see, alone, which aren't always accurate depictions of its identity. The BaYuCheng@yeah.net Ransomware, an estimated update of the Chinese XiaoBa Ransomware, is an example of how the looks of a Trojan can be more harmful than helpful for determining the right solutions. While this threat uses Japanese image components, like the second Trojan, its ransoming instructions are for victims fluent in Chinese.

Just like the other Trojan, the BaYuCheng@yeah.net Ransomware uses an encryption routine (AES and RSA-based) for blocking files and keeping other programs from opening them, with documents and similar, prominent media types being the usual targets. The BaYuCheng@yeah.net Ransomware also includes a variation of the XiaoBa Ransomware's extension-adding behavior but also inserts the threat actor's e-mail contact inside of brackets.

Related symptoms of the BaYuCheng@yeah.net Ransomware infections, as per malware experts confirmations, also include:

The BaYuCheng@yeah.net Ransomware delivers an advanced HTML, or HTA note containing part of its ransom demands and a request for contacting the threat actor. This component is identical to similar ones in the Dharma Ransomware family.
The BaYuCheng@yeah.net Ransomware loads a pop-up, similar to the XiaoBa Ransomware, which also uses a Visual Basic file for playing a looping audio clip.
The BaYuCheng@yeah.net Ransomware also maintains system persistence and uses excessive CPU resources while doing so, which may cause instability and performance problems in other programs.

Fresh Reasons for Bewaring of Fake Documents

The BaYuCheng@yeah.net Ransomware's samples are pretending to be PDF documents and might be installing themselves after gaining access to a PC by spam e-mails. The templates of these hoaxes often use themes including package delivery services, office equipment notifications, messages from coworkers, or warnings regarding taxes or billing. In many cases, malware experts connect associated drive-by-download attacks to victims enabling macros in documents for the Microsoft's Word program.

Contact an experienced cyber-security expert for any help you may need with determining whether or not the BaYuCheng@yeah.net Ransomware's locked files are decryptable. Paying ransoms for unlocking your media always includes some risk that the threat actor will defraud the user and is one of several reasons why malware experts encourage your keeping backups. Windows-compatible anti-malware products also should delete the BaYuCheng@yeah.net Ransomware without allowing any encryption.

The BaYuCheng@yeah.net Ransomware offers both misleading extensions and equally disingenuous ransom notes to anyone whose PC suffers from an infection. The appearance of a Trojan is often no more than surface-deep, and looking at it never should take the place of analyzing a threat with a dedicated security program.
