The Week in Review from Stamus Labs

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: 1204

This week, in addition to daily ruleset and IOC updates, we provided Stamus Security Platform customers with the following improved defense(s):

New threat detection(s) added [1]: 0
Major changes to detections(s) [2]: 374
Updated threat detection(s) [3]: 374

Major Detection Changes

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

Fake Browser (Trojan)

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.

Added kill chain phase(s): exploitation
Previously supported kill chain phase(s): delivery, exploitation, command and control
MITRE ATT&CK added: T1189
Previously existing MITRE ATT&CK: T1189
Methods added: 15

Keitaro (Phishing)

Cyber criminals exploited the TDS platform Keitaro to redirect users to malware exploit kits RIG and Fallout, infecting them with malicious software. Legitimate TDS platforms are used for targeted advertising.

Added kill chain phase(s): exploitation
Previously supported kill chain phase(s): exploitation, delivery, command and control
Methods added: 2

LandUpdate808 (Trojan)

Fake update variants like SocGholish, Clear Fake, Smart Ape, and ClickFix are being tracked by a collaboration introducing the LandUpdate808 Fake Update Variant.

Added kill chain phase(s): command and control
Previously supported kill chain phase(s): delivery, command and control
MITRE ATT&CK added: T1189
Previously existing MITRE ATT&CK: T1189
Methods added: 3

Lumma (Data Theft)

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

Added kill chain phase(s): command and control, actions on objectives

Methods added: 175

NetSupport RAT (RAT)

Remote Access Trojans allow covert surveillance and unauthorized access to victim PCs, collecting keystrokes, passwords, screenshots, and more. They differ from keyloggers by providing remote access capabilities to attackers.

Added kill chain phase(s): command and control
Previously supported kill chain phase(s): actions on objectives, command and control, exploitation, installation
MITRE ATT&CK added: T1105
Previously existing MITRE ATT&CK: T1587, T1105
Methods added: 2

RAT Generic (RAT)

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.

Added kill chain phase(s): command and control
Previously supported kill chain phase(s): installation, command and control, actions on objectives, delivery
MITRE ATT&CK added: T1573
Previously existing MITRE ATT&CK: T1071, T1041, T1573
Methods added: 1

Raspberry Robin (Trojan)

Raspberry Robin malware discovered in telecom and government systems in September. It has over 10 layers of obfuscation and delivers a fake payload when detecting security tools.

Added kill chain phase(s): command and control
Previously supported kill chain phase(s): command and control
Methods added: 48

SideWinder (APT)

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.

Added kill chain phase(s): command and control
Previously supported kill chain phase(s): command and control, delivery, actions on objectives
Methods added: 6

SocGholish (Social Engineering)

Malwarebytes found a new social engineering toolkit that uses compromised websites to perform advanced fingerprinting checks and deliver the NetSupport RAT payload.

Added kill chain phase(s): command and control
Previously supported kill chain phase(s): command and control, exploitation, delivery, reconnaissance, actions on objectives
MITRE ATT&CK added: T1189
Previously existing MITRE ATT&CK: T1027, T1189, T1071
Methods added: 4

TA4903 (APT)

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.

Added kill chain phase(s): delivery
Previously supported kill chain phase(s): delivery
Methods added: 3

TA582 (APT)

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.

Added kill chain phase(s): command and control
Previously supported kill chain phase(s): command and control
Methods added: 27

XWorm (RAT)

Cyble research labs found a malware developer advertising a powerful Windows RAT on the dark web during a threat-hunting exercise.

Added kill chain phase(s): command and control
