What is Dacls?

Dacls is the name of a remote access Trojan (RAT), a malicious program that allows cyber criminals to control infected computers remotely.

Research shows that this malware is tied to Lazarus Group (a group of cyber criminals) and targets Linux and the Windows Operating System. Typically, cyber criminals use RATs to steal sensitive, confidential information, infect systems with other malware, and so on. In any case, no RAT is harmless and should be uninstalled immediately.

What is [ponce.lorena@aol.com]?

Discovered by GrujaRS, [ponce.lorena@aol.com] is malicious software belonging to the GlobeImposter ransomware family. This malware operates by encrypting data and demanding payment for decryption tools/software. During the encryption process, all affected files are appended with the ".[ponce.lorena@aol.com]" extension.

For example, a file called "1.jpg" would appear as "1.jpg.[ponce.lorena@aol.com]", and so on. After this process is complete, an HTML file named "HOW_RECOVER.html" is created on the desktop.

What is MZ434376?

Discovered by GrujaRS, MZ434376 is a malicious program belonging to the KesLan ransomware family. It is designed to encrypt data and then demand ransom payments for decryption. During the encryption process, all compromised files are renamed with the ".MZ434376" extension.

For example, "1.jpg" appears as "1.jpg.MZ434376" following encryption. After this process is complete, the ransomware stores an HTML application called "Beni_Oku!!!.hta" on the desktop. This file contains the ransom message in Turkish.

What is Rdp?

Discovered by S!Ri, Rdp belongs to a family of ransomware-type programs called Paradise. Like many other programs of this type, Rdp encrypts files with a strong encryption algorithm so that they cannot be used or accessed unless they are decrypted with specific tools.

These can only be purchased from the cyber criminals who designed this ransomware. Furthermore, Rdp creates a ransom message within the "%%_WHERE_MY_FILES_=#.html" file and renames all encrypted files by adding the victim's ID, email address of the cyber criminals, and appending the ".rdp" extension to filenames.

For example, "1.jpg" would become "1.jpg[id-sw4uXZP5].[rdpconnect@protonmail.com].Rdp", and so on.

What is "Christmas Party Email"?

"Christmas Party Email" is a Christmas-themed spam campaign designed to spread Emotet Trojan-type malicious software. Through use of social engineering tactics, these emails are intended to trick users into opening the attached file, which will then in turn infect their systems with Emotet.

What is Deniz_Kızı?

Discovered by Raby, Deniz_Kızı ransomware is named (in Turkish) after a mythical creature, a mermaid. Like most programs of this type, Deniz_Kızı is designed to encrypt data so that victims cannot access it unless they pay a ransom. Instructions about how to pay are provided in the "Please Read Me!!!.hta" file.

Furthermore, Deniz_Kızı changes the extension of every encrypted file to ".Deniz_Kizi". For example, "1.jpg" becomes "1.jpg.Deniz_Kizi", and so on. Other variants of this ransomware use the ".Deniz_Kızı" extension for encrypted files.
