Welcome to the weekly threat detection update report from Stamus Networks. Each week, you will receive this email with a summary of the updates.
Current Stamus Threat Intelligence (STI) release version: 628
This week, in addition to daily ruleset and IOC updates, we provided Stamus Security Platform customers with the following improved defense(s):
Note: a "method" as referenced below, is a discrete detection vector for a given threat.
The following detections were added to your Stamus Security Platform this past week:
A Trojan horse or Trojan is a type of malware that is often disguised as legitimate software. Trojans can be employed by cyber-thieves and hackers trying to gain access to users' systems. Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems. Once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system. Kaspersky

The malware delivery method pioneered by the threat actors behind the REvil ransomware and the Gootkit banking Trojan has been enjoying a renaissance of late, as telemetry indicates that criminals are using the method to deploy an array of malware payloads in South Korea, Germany, France, and across North America.
The Gootkit malware family has been around more than half a decade – a mature Trojan with functionality centered around banking credential theft. In recent years, almost as much effort has gone into improvement of its delivery method as has gone into the NodeJS-based malware itself. Sophos

Ransom malware, or ransomware, is a type of malware that prevents users from accessing their system or personal files and demands ransom payment in order to regain access. The earliest variants of ransomware were developed in the late 1980s, and payment was to be sent via snail mail. Today, ransomware authors order that payment be sent via cryptocurrency or credit card. Malwarebytes

The following detections were updated this past week with changes to kill chain phase(s) or MITRE ATT&CK tactic(s)/technique(s):
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

Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems. Once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system. Kaspersky
Gamaredon Group is a threat group that has been active since at least 2013 and has targeted individuals likely involved in the Ukrainian government. The name Gamaredon Group comes from a misspelling of the word "Armageddon", which was detected in the adversary's early campaigns. MITRE

Cyber criminals violated the law TDS (Traffic Direction System) platform Keitaro and used it to redirect them users in exploit kits RIG and Fallout in order to infect them with malicious software.
TDS platforms are designed for redirection of users in particular sites. Legitimate TDS platforms, such as Keitaro, are mainly used by individuals and companies that want to advertise services or their products. Platforms drive users to the pages that companies want, targeting specific customers and promoting an ad campaign. techbizweb
Raccoon is a stealer and collects "passwords, cookies and autofill from all popular browsers (including FireFox x64), CC data, system information, almost all existing desktop wallets of cryptocurrencies". Malpedia
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
Silence is a financially motivated threat actor targeting financial institutions in different countries. The group was first seen in June 2016. Their main targets reside in Russia, Ukraine, Belarus, Azerbaijan, Poland and Kazakhstan. They compromised various banking systems, including the Russian Central Bank's Automated Workstation Client, ATMs, and card processing. MITRE
It leverages compromised websites and performs some of the most creative fingerprinting checks we’ve seen, before delivering its payload (NetSupport RAT). Malwarebytes
DPRK APT actor tracked by Proofpoint as TA444 Malpedia
Proofpoint researchers have identified a years-long social engineering and targeted malware campaign by the Iranian-state aligned threat actor TA456. Using the social media persona “Marcella Flores,” TA456 built a relationship across corporate and personal communication platforms with an employee of a small subsidiary of an aerospace defense contractor. In early June 2021, the threat actor attempted to capitalize on this relationship by sending the target malware via an ongoing email communication chain. Designed to conduct reconnaissance on the target’s machine, the macro-laden document contained personalized content and demonstrated the importance TA456 placed on the target. Once the malware, which is an updated version of Liderc that Proofpoint has dubbed LEMPO, establishes persistence, it can perform reconnaissance on the infected machine, save the reconnaissance details to the host, exfiltrate sensitive information to an actor-controlled email account via SMTPS, and then cover its tracks by deleting that day’s host artifacts.

Again, the generic nature of this detection means that the Payloads performed by this group of trojans may be highly variable, and therefore difficult to describe specifically. This group of trojans has been observed to perform any, or all, of the following actions:
redirect Web traffic
Stealer: 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
