Remote Access Trojans are programs that provide the capability to allow covert surveillance or the ability to gain unauthorized access to a victim PC. Remote Access Trojans often mimic similar behaviors of keylogger applications by allowing the automated collection of keystrokes, usernames, passwords, screenshots, browser history, emails, chat lots, etc. Remote Access Trojans differ from keyloggers in that they provide the capability for an attacker to gain unauthorized remote access to the victim machine via specially configured communication protocols which are set up upon initial infection of the victim computer. This backdoor into the victim machine can allow an attacker unfettered access, including the ability to monitor user behavior, change computer settings, browse and copy files, utilize the bandwidth (Internet connection) for possible criminal activity, access connected systems, and more.

The ERMAC Android banking trojan has released version 2.0, increasing the number of applications targeted from 378 to 467, covering a much wider range of apps to steal account credentials and crypto wallets.
The goal of the trojan is to send stolen login credentials to threat actors, who then use them to take control of other people’s banking and cryptocurrency accounts and conduct financial or other forms of fraud.
ERMAC is currently sold to members of darknet sites at a subscription rate of $5,000 per month, which is $2k over the price tag of the first version, reflecting the upgrade in features and its popularity. Bleepingcomputer

DPRK APT actor tracked by Proofpoint as TA444 Malpedia
The following detections were updated this past week with changes to kill chain phase(s) or MITRE ATT&CK tactic(s)/technique(s):
APT29 is threat group that has been attributed to the Russian government and has operated since at least 2008. This group reportedly compromised the Democratic National Committee starting in the summer of 2015. MITRE
Magic Hound is an Iranian-sponsored threat group that conducts long term, resource-intensive cyber espionage operations, likely on behalf of the Islamic Revolutionary Guard Corps. They have targeted U.S. and Middle Eastern government and military personnel, academics, journalists, and organizations such as the World Health Organization (WHO), via complex social engineering campaigns since at least 2014. MITRE
Ave Maria is high-risk trojan designed to steal various information and to cause "chain infections" (spread other infections). It is typically proliferated using various spam email campaigns. Criminals send thousands of deceptive emails that contain infectious attachments, most of which are Microsoft Office (typically Excel) files. Emails are delivered with messages encouraging users to open the attached document, however, this results in infiltration of Ave Maria Pcrisk
The term info stealer is self-explanatory. This type of malware resides in an infected computer and gathers data in order to send it to the attacker. Typical targets are credentials used in online banking services, social media sites, emails, or FTP accounts.
Info stealers may use many methods of data acquisition. The most common are:
hooking browsers (and sometimes other applications) and stealing credentials that are typed by the user using web injection scripts that are adding extra fields to web forms and submitting information from them to a server owned by the attacker form grabbing (finding specific opened windows and stealing their content) keylogging stealing passwords saved in the system and cookies Modern info stealers are usually parts of botnets. Sometimes the target of attack and related events are configured remotely by the command sent from the Command and Control server (C&C). Malwarebytes

APT17 is a China-based threat group that has conducted network intrusions against U.S. government entities, the defense industry, law firms, information technology companies, mining companies, and non-government organizations. MITRE
This Trojan arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites. Trendmicro
Kimsuky is a North Korean-based threat group that has been active since at least September 2013. The group initially focused on targeting Korean think tanks and DPRK/nuclear-related targets, expanding recently to the United States, Russia, and Europe. The group was attributed as the actor behind the Korea Hydro & Nuclear Power Co. compromise. MITRE
Malware of this family consists of Trojans that use anti-emulation, anti-debugging, and code obfuscation to prevent their analysis. Kaspersky
OilRig is a suspected Iranian threat group that has targeted Middle Eastern and international victims since at least 2014. The group has targeted a variety of industries, including financial, government, energy, chemical, and telecommunications, and has largely focused its operations within the Middle East. It appears the group carries out supply chain attacks, leveraging the trust relationship between organizations to attack their primary targets. FireEye assesses that the group works on behalf of the Iranian government based on infrastructure details that contain references to Iran, use of Iranian infrastructure, and targeting that aligns with nation-state interests.This group was previously tracked under two distinct groups, APT34 and OilRig, but was combined due to additional reporting giving higher confidence about the overlap of the activity. MITRE
PlugX is a remote access tool (RAT) that uses modular plugins. It has been used by multiple threat groups. MITRE
Remcos is a closed-source tool that is marketed as a remote control and surveillance software by a company called Breaking Security.
Remcos has been observed being used in malware campaigns.
Sality is the classification for a family of malicious software (malware), which infects files on Microsoft Windows systems. Sality was first discovered in 2003 and has advanced over the years to become a dynamic, enduring and full-featured form of malicious code. Systems infected with Sality may communicate over a peer-to-peer (P2P) network to form a botnet for the purpose of relaying spam, proxying of communications, exfiltrating sensitive data, compromising web servers and/or coordinating distributed computing tasks for the purpose of processing intensive tasks (e.g. password cracking). Since 2010, certain variants of Sality have also incorporated the use of rootkit functions as part of an ongoing evolution of the malware family. Because of its continued development and capabilities, Sality is considered to be one of the most complex and formidable forms of malware to date. Wikipedia
An actor mainly targeting Pakistan military targets, active since at least 2012. We have low confidence that this malware might be authored by an Indian company. To spread the malware, they use unique implementations to leverage the exploits of known vulnerabilities (such as CVE-2017-11882) and later deploy a Powershell payload in the final stages. Malpedia
Silent Librarian is a group that has targeted research and proprietary data at universities, government agencies, and private sector companies worldwide since at least 2013. Members of Silent Librarian are known to have been affiliated with the Iran-based Mabna Institute which has conducted cyber intrusions at the behest of the government of Iran, specifically the Islamic Revolutionary Guard Corps (IRGC).[ MITRE
It leverages compromised websites and performs some of the most creative fingerprinting checks we’ve seen, before delivering its payload (NetSupport RAT). Malwarebytes

A dropper is a kind of Trojan that has been designed to "install" some sort of malware (virus, backdoor, etc.) to a target system. The malware code can be contained within the dropper (single-stage) in such a way as to avoid detection by virus scanners or the dropper may download the malware to the target machine once activated (two stage).
