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: 675
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 NDR this past week:
IDP is a plugin for Inno Setup, which allows you to download files as part of your installation. Mitrichsoftware
InnoDownloadPlugin - abuse.ch | InnoDownloadPlugin - anyrun | InnoDownloadPlugin -jrsoftware |
ThreatLabz discovered that threat actors are now distributing ArkeiStealer through Windows Installer binaries which masquerade as a trading application. The trading application is backdoored with the SmokeLoader downloader which further downloads an information stealer. In May 2021 in a similar campaign, ThreatLabz identified a fake TradingView website and backdoored TradingView application associated with the MineBridge RAT campaign. Zscaler

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

An advanced persistent threat (APT) is a stealthy threat actor, typically a nation state or state-sponsored group, which gains unauthorized access to a computer network and remains undetected for an extended period.[1][2] In recent times, the term may also refer to non-state-sponsored groups conducting large-scale targeted intrusions for specific goals.

The following detections were updated this past week with changes to kill chain phase(s) or MITRE ATT&CK tactic(s)/technique(s):
VICEROY TIGER is an adversary with a nexus to India that has historically targeted entities throughout multiple sectors. Older activity targeted multiple sectors and countries; however, since 2015 this adversary appears to focus on entities in Pakistan with a particular focus on government and security organizations. This adversary consistently leverages spear phishing emails containing malicious Microsoft Office documents, malware designed to target the Android mobile platform, and phishing activity designed to harvest user credentials. In March 2017, the 360 Chasing Team found a sample of targeted attacks that confirmed the previously unknown sample of APT's attack actions, which the organization can now trace back at least in April 2016. The chasing team named the attack organization APT-C-35. In June 2017, the 360 Threat Intelligence Center discovered the organization’s new attack activity, confirmed and exposed the gang’s targeted attacks against Pakistan, and analyzed in detail. The unique EHDevel malicious code framework used by the organization. Malpedia
APT28 (also known as - Fancy Bear/Sofacy/Strontum) is a threat group that has been attributed to Russia's Main Intelligence Directorate of the Russian General Staff by a July 2018 U.S. Department of Justice indictment.
This group reportedly compromised the Hillary Clinton campaign, the Democratic National Committee, and the Democratic Congressional Campaign Committee in 2016 in an attempt to interfere with the U.S. presidential election. APT28 has been active since at least 2004.
APT37 is a North Korean state-sponsored cyber espionage group that has been active since at least 2012. The group has targeted victims primarily in South Korea, but also in Japan, Vietnam, Russia, Nepal, China, India, Romania, Kuwait, and other parts of the Middle East. APT37 has also been linked to the following campaigns between 2016-2018: Operation Daybreak, Operation Erebus, Golden Time, Evil New Year, Are you Happy?, FreeMilk, North Korean Human Rights, and Evil New Year 2018.[1][2][3] MITRE
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
The IcedID banking Trojan was discovered by IBM X-Force researchers in 2017. At that time, it targeted banks, payment card providers, mobile services providers, payroll, webmail and e-commerce sites, mainly in the U.S. IcedID has since continued to evolve, and while one of its more recent versions became active in late-2019, X-Force researchers have identified a new major version release that emerged in 2020 with some substantial changes. securityintelligence.com
The main objective of PhantomLance is to harvest confidential information from the victim’s device. The malware is able to supply its handlers with location data, call logs, text messages, lists of installed apps, and full information about the infected smartphone. What’s more, its functionality can be expanded at any moment simply by loading additional modules from the C&C server. Kaspersky

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. Malwarebytes
It leverages compromised websites and performs some of the most creative fingerprinting checks we’ve seen, before delivering its payload (NetSupport RAT). Malwarebytes
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. PFPT
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).

Malicious programs of this family secretly send information to the criminal from the user’s infected Android mobile device. Kaspersky
During a routine threat-hunting exercise, Cyble research labs discovered a dark web post where a malware developer was advertising a powerful Windows RAT. Cyble
