Conti Ransomware: The Conti ransomware family was discovered using multiple techniques to find files to attack and how the encryption process is carried out. The malware uses multiple threads to encrypt files at a faster rate compared to other ransomware families and contains command-line options to scan for local files as well as remote files over SMB shares. Conti also uses the Windows Restart Manager to free up files that are open by various applications. The ransomware uses AES-256 encryption and requires the victim to email the threat actor for the decryption key. Variants of the malware post stolen data from entities who refuse to pay the ransom.

TrickBot Banker: TrickBot is one of the most popular type of trojan. It started first in 2016 as a banking trojan and has evolved with spyware capabilities. It is customisable to make it more effective and profitable. This means that not all TrickBot infections will be the same. TrickBot is not openly advertised, but is only distributed across an elite group of criminals in the underground. TrickBot infects machine most often through malicious documents. Once installed on a target system, TrickBot will download other types of malware.

Egregor Ransomware: Egregor ransomware exfiltrates sensitive information before encrypting files and gives the victim three days to contact the threat actor or the stolen data will be posted online. The malicious software is a variant of the Sekhmet ransomware family and uses multiple techniques to bypass defense measures including obfuscation, software packing, and sandbox evasion. The ransom note reports the actor is willing to provide security recommendations to the victim to avoid being breached again.

Phobos Ransomware: The Phobos ransomware uses AES encryption and adds various extensions to infected files. Phobos was identified late 2017 with new variants discovered throughout 2019 and into 2020. Victim’s are required to communicate with the threat actor(s) via email at one of many email addresses used to obtain a decryption key. Analysis of Phobos has identified similarities shared with other ransomware families such as Dharma and CrySiS.

Donot Group: The APT group Donot (also known as APT-C-35, Donot Team) has been active for several years, the exact start date is still unknown. The attackers are interested in confidential information and intellectual property.

The maldocs contain embedded DLL’s and often referenced geopolitical themes, for example: “The New US Administration”. Donot Team’s development of mobile malware included fake Android APKs that were meant to exploit Google’s Cloud messaging service, bypass detection and act as a Command-And-Control (C2). The origin of Donot Team is unclear; however, it is speculated that Donot Team may have ties to India due to targets of interest, analysis of malware code and infrastructure re-use.

Remcos RAT: Remcos is a remote access technology that is developed and maintained by the cyber security firm BreakingSecurity.

The backdoor itself is equipped with tooling that provides screen captures and remote file manipulation.

Turla: Based on OSINT, TTP, and malware analysis, results are received and assessed on a daily basis.
