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):

 

ClickFix (Phishing)

 

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.

 

• Added kill chain phase(s): delivery

• Previously supported kill chain phase(s): exploitation, delivery, command and control, installation

• MITRE ATT&CK added: T1189

• Previously existing MITRE ATT&CK: T1071, T1027, T1189, T1105, T1102, T1566, T1036

• Methods added: 1

 

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: T1071, T1189

• Methods added: 12

 

Havoc (Offensive Tools)

 

Havoc is a flexible post-exploitation command and control framework developed by @C5pider, available on Github for use.

 

• Added kill chain phase(s): command and control

• Previously supported kill chain phase(s): command and control

• Methods added: 6

 

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, exploitation, actions on objectives

• MITRE ATT&CK added: T1189

• Previously existing MITRE ATT&CK: T1189, T1105, T1071

• 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

• Previously supported kill chain phase(s): actions on objectives, command and control, installation, delivery

• MITRE ATT&CK added: T1071

• Previously existing MITRE ATT&CK: T1005, T1071, T1573, T1105

• Methods added: 15

 

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: T1071, T1105

• Methods added: 1

 

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

• Methods added: 12

 

Unknown APT (APT)

 

Sophisticated adversary with expertise and resources uses multiple attack vectors to establish presence in organizations' IT infrastructure, exfiltrate information, undermine missions, and persistently adapt to defenders.

 

• Added kill chain phase(s): command and control

• Previously supported kill chain phase(s): command and control, delivery, actions on objectives

• MITRE ATT&CK added: T1041

• Previously existing MITRE ATT&CK: T1041, T1071, T1001, T1566, T1102, T1105

• Methods added: 2

• MITRE ATT&CK added: T1573

• Previously existing MITRE ATT&CK: T1071, T1573

• Methods added: 38
