Viruses

Trojan:Win32/Commandrob.A!ml is a heuristic detection used to identify a type of Trojan Horse malware. This malware typically infiltrates a system by disguising itself as legitimate software, often through malicious email attachments or compromised websites. Once installed, the Trojan can perform various harmful activities, such as downloading and installing additional malware, logging keystrokes, and stealing sensitive information like usernames and passwords. It can also grant remote access to hackers, allowing them to take control of the compromised system. This Trojan is particularly dangerous because it can operate silently in the background, making it difficult for users to detect its presence. Employing robust antivirus software and regularly updating it is crucial to protect against such threats. Always exercise caution when downloading files or clicking on links from untrusted sources.

AttackNew Ransomware is a malicious software variant belonging to the MedusaLocker ransomware family, which aims to extort money from victims by encrypting files and demanding a ransom for their release. Upon executing this malware on a test system, it was observed that it appended an extension, such as .attacknew1, to the names of the encrypted files. This ransomware uses sophisticated cryptographic algorithms like RSA and AES, making decryption extremely challenging without the unique decryption keys that the attackers possess. After successful encryption, it generates a ransom note named how_to_back.html, which can typically be found on the victim's desktop or within affected directories. This note informs victims that their company's network has been compromised and that their files are encrypted, emphasizing that any attempt to decrypt the files without the attackers' help will lead to data corruption.

Mango Ransomware is a sophisticated type of malware belonging to the Phobos ransomware family, identified during routine security inspections. This malware encrypts files on the infected system and appends a unique file extension to each compromised file, dramatically altering its filename. Specifically, it appends a combination of a unique ID specific to the victim, the cybercriminal’s email address, and the extension .mango to the original filenames. For example, a file initially named picture.jpg would be altered to picture.jpg.id[unique_id].email[mango@onionmail.com].mango. The encryption algorithm employed by Mango Ransomware is complex and highly efficient, making decryption without the proper key extremely challenging. Upon encrypting the files, the ransomware generates two types of ransom notes: one displayed in a pop-up window titled info.hta and another created as a text file named info.txt deposited onto the desktop and within all encrypted directories.

Griffin Ransomware, recognized for its severe impact on victims, is a malicious program designed to encrypt files and extort payments for their decryption. This ransomware primarily changes the names of the encrypted files to a random character string, appending the .griffin extension to each file. It employs robust encryption algorithms, making it difficult for any unauthorized party to access the locked files without the appropriate decryption key held by the attackers. Upon successful encryption, Griffin Ransomware generates a ransom note, typically titled #Recovery.txt, and drops it onto the desktop or into folders containing the infected files. The ransom note informs victims of the encryption, providing contact details for the cybercriminals while also implying a severe financial consequence if the ransom is not paid promptly.

iTerm2 is a popular terminal emulator designed for macOS, providing advanced features like split panes, session restoration, and extensive customization options. However, the trojanized version of iTerm2 malware functions as a backdoor, surreptitiously installing additional malicious software onto the system. This fake application can significantly compromise the device, leading to severe privacy breaches, data theft, and financial losses. Once installed, the malware can exfiltrate sensitive information, monitor user activities, and even grant remote access to cybercriminals. Consequently, affected systems may experience degraded performance, unauthorized data transmission, and potentially, identity theft. Users are advised to download software exclusively from verified sources to avoid such infections. Employing robust antivirus solutions is also essential to detect and eliminate this and similar threats effectively.

Trojan:VBS/Pordeezy!lnk is a type of malware that leverages malicious Visual Basic script to execute harmful actions on a compromised Windows machine. This Trojan often disguises itself as a legitimate application, tricking users into installing it. Once installed, it can perform a variety of malicious activities, including disrupting online connectivity, initiating unauthorized file transfers, and downloading additional malware from remote servers. The Trojan may modify shortcut links on the desktop or in the start menu, causing these links to execute harmful scripts each time they are clicked. Symptoms of infection can include unexpected browser redirects, sluggish system performance, and alerts from antivirus programs. Immediate removal is recommended to prevent further damage and potential data loss. Employing reliable antivirus tools and running scans in Safe Mode can help detect and eliminate this threat effectively.

Magniber Ransomware (My Decryptor Ransomware) is a wide-spread crypto-virus, that targets Windows-PCs. Focuses on English and South Korean users. Since June 2018, Magniber attacks have shifted to other countries in the Asia-Pacific region: China, Hong Kong, Taiwan, Singapore, Malaysia, Brunei, Nepal and others. The virus got its name from the combination of the two words Magnitude + Cerber. Here, Magnitude is a collection of exploits, the last for Cerber is the vector of infection. With this threat, the Cerber malware ended its distribution in September 2017. But on the Tor site of the ransomware it is stated: My Decryptor, here is where second part of the name came from. After encryption, Magniber My Decryptor Ransomware can add 5-6-7-8 or 9 random letters as file extension. During the years ransomware used various names for ransom note files: _HOW_TO_DECRYPT_MY_FILES_[random]_.txt, READ_ME_FOR_DECRYPT_[random]_.txt, READ_ME_FOR_DECRYPT.txt. But the most actual is READ_ME.txt.

Qilin Ransomware is a formidable threat that belongs to the Agenda family of ransomware, known for its ability to encrypt various file types including documents, images, and videos, rendering them inaccessible to the user. Upon infection, it appends a unique string in the form of a file extension to each targeted file, which can be represented as *.random_string. This transformation indicates that the file has been compromised, and access has been effectively locked by the attackers. Alongside this encryption, Qilin Ransomware generates a ransom note, titled [random_string]-RECOVER-README.txt, which is placed in every folder containing encrypted files. This document contains critical information regarding the attack, including instructions on how to contact the attackers and details regarding the ransom payment for the decryption key.
