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: 1192
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 (SSP) this past week:
BugSleep is a backdoor used to execute commands and transfer files between compromised machines and C&C servers. It is under development, with threat actors enhancing functionality and addressing bugs.
TrickMo is a mobile banking trojan that bypasses 2FA, likely distributed by TrickBot. It targets users in Germany to steal one-time passwords (TANs) used for transaction authorization.
TrickMo - Malpedia | TrickMo - Cleafy |
MintsLoader is a malware that spreads through phishing emails targeting European organizations. It uses JavaScript and PowerShell in a multi-step infection process involving URLs with .top TLD and domain generation algorithm (DGA).

Loaders are basic remote access Trojans allowing attackers to control compromised computers or bots. They are traditionally lightweight to avoid detection, but can evolve with added features for cybercriminals.
The following detections were updated this past week with changes to kill chain phase(s) or MITRE ATT&CK tactic(s)/technique(s):
The stealer is written in PHP, packaged into an executable with 'ExeOutput', and virtualized with 'BoxedApp' for victims who cannot execute PHP code.
Over one million WordPress sites have been compromised by a campaign exploiting theme and plugin vulnerabilities to inject a Linux backdoor called Balad Injector since 2017, redirecting to fraudulent pages.
In April 2024, researchers found compromised sites leading to an iframe on pley[.]es showing an error message. The payload domain was taken offline, preventing infection. Later, the iframe was replaced with the ClearFake inject.
Attackers infect enterprise networks with malware by promoting fake browser updates on hacked websites, leading to the installation of banking trojans and later ransomware encryption on compromised networks.
Lumma is a C-based information stealer sold on Russian underground forums and Telegram by LummaC since August 2022. It targets cryptocurrency wallets and has file grabber capabilities.
Remote Access Trojans allow covert surveillance and unauthorized access to victim PCs, collecting data like keystrokes and screenshots. They differ from keyloggers by enabling remote access for attackers.
Actor targeting Pakistan military, linked to Indian company with unique malware implementations since 2012. Leverages CVE-2017-11882 exploits, deploys Powershell payload in final stages. Low confidence in attribution.
Malwarebytes found a new social engineering toolkit that uses compromised websites to perform advanced fingerprinting checks and deliver the NetSupport RAT payload.
Advanced persistent threats (APTs) are stealthy threat actors, often nation states or state-sponsored groups, who gain unauthorized access to networks for political or economic motivations, utilizing various tactics to remain undetected.
An APT is a stealthy threat actor, often nation state or state-sponsored, gaining unauthorized access and remaining undetected in a network for political or economic reasons, targeting various sectors.
CERT-UA report links threat group UAC-0050 to Russian-speaking mercenary organization The DaVinci Group, with ties to Russian law enforcement, targeting Ukrainian organizations since 2022 Russian invasion.
Cyble research labs found a malware developer advertising a powerful Windows RAT on the dark web during a threat-hunting exercise.
