LockBit 3.0 Ransomware: The LockBit ransomware-as-a-service (RaaS) family was discovered in 2019 with version 3.0 released in mid-2022. Improvements added by the threat actor include a new search tool on the site hosting the leaked data, new management features, and the acceptance of Zcash for payment. Version 3.0 of the malware also includes multiple techniques such as code packing and obfuscation to hinder analysis and the abuse of the Microsoft Connection Manager Profile Installer (CMSTP) to bypass UAC.

IcedID Banker: IcedID, also known as BokBot, is a modular banking trojan that targets user financial information and is capable of acting as a dropper for other malware. It uses a man-in-the-browser attack to steal financial information, including login credentials for online banking sessions. Once it successfully completes its initial attack, it uses the stolen information to take over banking accounts and automate fraudulent transactions. IcedID is primarily dropped as a secondary payload from other malware, most notably Emotet, in addition to its own malspam campaigns. IcedID uses multiple injection methods to evade antivirus and other malware detection methods, such as injecting itself into operating system (OS) memory and regular processes. The malware authors are known to update IcedID to increase persistence and evade new detection efforts.

BPFDoor: Multiple sectors including education, government, and logistics are being targeted with BPFDoor, Mangzamel, Gh0st, and Metasploit malware. Once compromised the malware communicates with the threat actor controlled C2 and to receive further instruction or payload delivery. Threat actors often leverage Virtual Private Servers for communication over TCP, UDP, and ICMP protocols. The Trellix ATR Team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports.

8220 Gang Expands Cloud Botnet: The 8220 Gang, also known as 8220 Mining Group, is targeting cloud hosts with the IRC botnet and PwnRig cryptocurrency miner. The threat actor exploits known vulnerabilities and uses brute force to gain initial access. Lateral movement is carried out using network scanning and hundreds of hardcoded SSH credentials. At the time of this writing the actor has infected around 30,000 devices with the malicious software.

Attacks on Goverment Agencies: The Trellix Email Security Research Team has discovered a malicious campaign targeting government agencies of Afghanistan, India, Italy, Poland, and the United States since 2021. The attack starts with a spear phishing email with a geo-political theme. The spear phishing emails were themed around India Afghanistan relationship. Attacker used politics as a lure to trick users into clicking on a malicious link. The email used for this phishing attack contains an attachment or a weaponized URL that delivers an Excel sheet. Upon opening the Excel sheet, Excel executes an embedded malicious macro which then decrypts and installs a Remote Access Trojan (AysncRAT & LimeRAT) and maintains persistence. Once the Remote Access Trojan is installed on the victim machine, it establishes communication with a Command-and-Control server used to exfiltrate victim data. The Remote Access Trojan is capable of taking screenshots, capturing keystrokes, recording credentials/confidential information, and adding infected systems to botnets. It can also perform network discovery and move laterally to other systems in the affected organization. The email used in this attack originated from the South Asia region which suggests the involvement of a South Asian threat actor. Trellix Email Security has detection coverage for this malicious campaign. The Trellix ATR Team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports.

APT34 Group: APT34 also known as OilRig among other aliases, is an APT group that has been active since 2014. This allegedly Iranian group has mostly focused on the Middle East targeting government, financial, telecommunications, energy, and chemical industries. This espionage motivated group uses techniques such as spear-phishing, targeted social engineering via LinkedIn, or mimicking sites offering jobs opening to gain the initial foothold into the targeted network. It then uses techniques like DNS tunneling to hide the communication with the C2 servers as well as hiding the commands in copies of legitimate websites. In 2019 an individual named “Lab Dookhtegan” leaked via a public Telegram channel the source code of a big portion of the APT34 arsenal. Since then the group has been busy updating their arsenal to avoid detection and proceed with their operations.

Iron Tiger Uses Updated SysUpdate Malware: The Iron Tiger threat group, also known as LuckyMouse, Emissary Panda, and APT27, targeted the government, bank, telecom, energy, and gaming sectors in the Middle East and Southeast Asia. The initial infection vector consisted of weaponized documents, the exploitation of Internet-facing applications, and watering-hole and supply-chain attacks. Iron Tiger updated their toolkit with a new variant of the SysUpdate malware family. The updated payload contains new and unique classes and uses a named pipe for communication. The malicious software uses DLL sideloading, WMI, and process injection for execution, privilege escalation, and defense evasion.

Fake McAfeePlugin.exe: One of the Trellix Threat Intelligence Group’s hunting actions is to identify tools that are acting as legitimate tools, in this case tools that are acting like legitimate tools of the McAfee Corporation. One of the tools found is an executable called McafeePlugin.exe. This tool was not signed by McAfee Corp. and was in a directory path which wasn’t the official install location. By studying the telemetry hits of this fake plugin, we observed detections in Portugal from an organization in the energy sector. The attacked system was an exposed VMware Horizon server. By pivoting on the IP of the targeted host, the Trellix Threat Intelligence Group was able to determine there were multiple malicious detections over the course of a month. These detections involved: -Coin miner linked traffic, previously observed in a Conti ransomware attack in Belgium as well as the regular XMRig miner. -A specific exploit, called vmware_kb.exe and used to exploit vulnerable VMware Horizon servers. This specific exploit is associated with the Sliver framework, an alternative to Cobalt Strike, and was previously observed in a Avos Locker attack. -Multiple PowerShell scripts reaching out to known C2 servers linked to Cobalt Strike and Log4Shell attacks. -Lastly a coin miner that was observed in a previous campaign involving the threat group Lazarus which led to a Nukesped infection.

Ukrainian Entities Attacked: Multiple threat groups including UNC1151 and UNC2589 targeted Ukrainian entities with malicious spear-phishing documents. The GrimPlant backdoor and GraphSteel information stealer were used to find and exfiltrate browser credentials along with system, network, user, and directory information. A registry run key was created for persistence while hidden windows, process injection, software packing, and timestomping were used for defense evasion.

Lockbit: Lockbit, a newer Ransomware-as-a Service, was identified in the first quarter of 2020 by a joint research effort from McAfee Labs and Northwave. Once a victim has been compromised, a ransom note is dropped by the malware reporting that in addition to encrypting files the threat actor has also exfiltrated private data including financial, personal, and network information. The ransom note further instructs the victim to a dark web address to regain access to their encrypted data. In more recent attacks, the threat actor has threatened to publish confidential data that has been exfiltrated if the ransom is not met within the time frame set by the threat actor. McAfee Labs will continue to update the Lockbit ransomware profile and disseminate information that is deemed appropriate regarding the Lockbit ransomware and victims.
