According to PCrisk, BlackMatter is a piece of malicious software categorized as ransomware. It operates by encrypting data for the purpose of making ransom demands for the decryption tools. In other words, files affected by BlackMatter are rendered inaccessible, and victims are asked to pay - to recover access to their data. During the encryption process, files are appended with an extension consisting of a random character string. For example, a file initially named "1.jpg" would appear as something similar to "1.jpg.k5RO9fVOl". After this process is complete, the ransomware changes the desktop wallpaper and created a ransom note - "[random_string].README.txt" (e.g., k5RO9fVOl.README.txt).

BlackEnergy, its first version shortened as BE1, started as a crimeware being sold in the Russian cyber underground as early as 2007. Initially, it was designed as a toolkit for creating botnets for conducting DDoS attacks. It supported a variety of flooding commands including protocols like ICMP, TCP SYN, UDP, HTTP and DNS. Among the high profile targets of cyber attacks utilising BE1 were a Norwegian bank and government websites in Georgia three weeks before Russo-Georgian War. Version 2 of BlackEnergy, BE2, came in 2008 with a complete code rewrite that introduced a protective layer, a kernel-mode rootkit and a modular architecture. Plugins included mostly DDoS attacks, a spam plugin and two banking authentication plugins to steal from Russian nad Ukrainian banks. The banking plugin was paired with a module designed to destroy the filesystem. Moreover, BE2 was able to - download and execute a remote file; - execute a local file on the infected computer; - update the bot and its plugins; The Industrial Control Systems Cyber Emergency Response Team issued an alert warning that BE2 was leveraging the human-machine interfaces of industrial control systems like GE CIMPLICITY, Advantech/Broadwin WebAccess, and Siemens WinCC to gain access to critical infrastructure networks. In 2014, the BlackEnergy toolkit, BE3, switched to a lighter footprint with no kernel-mode driver component. Its plugins included: - operations with victim's filesystem - spreading with a parasitic infector - spying features like keylogging, screenshoots or a robust password stealer - Team viewer and a simple pseudo “remote desktop” - listing Windows accounts and scanning network - destroying the system Typical for distribution of BE3 was heavy use of spear-phishing emails containing Microsoft Word or Excel documents with a malicious VBA macro, Rich Text Format (RTF) documents embedding exploits or a PowerPoint presentation with zero-day exploit CVE-2014-4114. On 23 December 2015, attackers behind the BlackEnergy malware successfully caused power outages for several hours in different regions of Ukraine. This cyber sabotage against three energy companies has been confirmed by the Ukrainian government. The power grid compromise has become known as the first-of-its-kind cyber warfare attack affecting civilians.

a backdoor that obfuscates its communications as normal traffic to legitimate websites such as Github and Microsoft's Technet portal.

ALPHV, also known as BlackCat or Noberus, is a ransomware family that is deployed as part of Ransomware as a Service (RaaS) operations. ALPHV is written in the Rust programming language and supports execution on Windows, Linux-based operating systems (Debian, Ubuntu, ReadyNAS, Synology), and VMWare ESXi. ALPHV is marketed as ALPHV on cybercrime forums, but is commonly called BlackCat by security researchers due to an icon of a black cat appearing on its leak site. ALPHV has been observed being deployed in ransomware attacks since November 18, 2021. ALPHV can be configured to encrypt files using either the AES or ChaCha20 algorithms. In order to maximize the amount of ransomed data, ALPHV can delete volume shadow copies, stop processes and services, and stop virtual machines on ESXi servers. ALPHV can self-propagate by using PsExec to remote execute itself on other hosts on the local network.

According to Bitdefender, BitRAT is a notorious remote access trojan (RAT) marketed on underground cybercriminal web markets and forums. Its price tag of $20 for lifetime access makes it irresistible to cybercriminals and helps the malicious payload spread. Furthermore, each buyer’s modus operandi makes BitRAT even harder to stop, considering it can be employed in various operations, such as trojanized software, phishing and watering hole attacks. BitRAT’s popularity arises from its versatility. The malicious tool can perform a wide range of operations, including data exfiltration, UAC bypass, DDoS attacks, clipboard monitoring, gaining unauthorized webcam access, credential theft, audio recording, XMRig coin mining and generic keylogging.

BianLian is a GoLang-based ransomware that continues to breach several industries and demand large ransom amounts. The threat actors also use the double extortion method by stealing an affected organization’s files and leaking them online if the ransom is not paid on time. BianLian gains access to victim systems through valid Remote Desktop Protocol (RDP) credentials, uses open-source tools and command-line scripting for discovery and credential harvesting, and exfiltrates victim data via File Transfer Protocol (FTP), Rclone, or Mega. BianLian originally employed a double-extortion model in which they encrypted victims’ systems after exfiltrating the data; however, around January 2023, they shifted to primarily exfiltration-based extortion. The BianLian ransomware uses goroutines and encrypts files in chunks to quickly hijack an infected system. The ransomware adds its own extension to each encrypted file.

Once set up in the system, Trojan.Belonard replaces the list of available game servers in the game client and creates proxies on the infected computer to spread the Trojan. As a rule, proxy servers show a lower ping, so other players will see them at the top of the list. By selecting one of them, a player gets redirected to a malicious server where their computer become infected with Trojan.Belonard.
