MITRE ATT&CK

Techniques & procedures

10 distinct techniques documented for this family, organized by ATT&CK tactic.

Execution

1 technique

T1059Command and Scripting InterpreterEvidence1

It harvests a wide array of sensitive data, including credentials from browser storage across Chrome, Safari, Firefox, and Brave, as well as terminal command histories...

Persistence

1 technique

T1543.001Launch AgentEvidence1

Persistence is achieved through a LaunchAgent. This implant’s plist carries the Label value com.apple.system.services.activity.

Privilege Escalation

1 technique

T1543.001Launch AgentEvidence1

Persistence is achieved through a LaunchAgent. This implant’s plist carries the Label value com.apple.system.services.activity.

Stealth

4 techniques

T1027Obfuscated Files or InformationEvidence1

To avoid static analysis, it resolves its API calls at runtime via dlsym, steering clear of static symbol tables, and determines its own executable location dynamically.

T1036MasqueradingEvidence1

This implant’s plist carries the Label value com.apple.system.services.activity. Masquerading within Apple’s com.apple.* namespace is a tactic widely used in many macOS malware families, including those previously tied to DPRK-linked activities.

T1070Indicator RemovalEvidence1

Gaslight employs runtime self-redaction, stripping the token from its own output to prevent recovery from crash artifacts or memory dumps.

T1497Virtualization/Sandbox EvasionEvidence1

The most notable feature of Gaslight is its defensive strategy, which pivots from conventional sandbox evasion to active deception of the investigative process.

Credential Access

1 technique

T1555Credentials from Password StoresEvidence1

It harvests a wide array of sensitive data, including credentials from browser storage across Chrome, Safari, Firefox, and Brave... Crucially, the implant also targets the host's login keychain-db.

Discovery

2 techniques

T1082System Information DiscoveryEvidence1

It harvests a wide array of sensitive data, including ... installed application listings, and process snapshots captured via ps aux.

T1497Virtualization/Sandbox EvasionEvidence1

The most notable feature of Gaslight is its defensive strategy, which pivots from conventional sandbox evasion to active deception of the investigative process.

Command and Control

2 techniques

T1071.001Web ProtocolsEvidence1

Communication with the attacker is handled via a command-and-control loop operating over the Telegram Bot API, utilizing AES-GCM encrypted payloads over certificate-pinned TLS.

T1573Encrypted ChannelEvidence1

Communication with the attacker is handled via a command-and-control loop operating over the Telegram Bot API, utilizing AES-GCM encrypted payloads over certificate-pinned TLS.

macOS Gaslight Backdoor Weaponizes Prompt Injection Against Security Analysts - Decipher

A Rust-based macOS backdoor and infostealer that uses prompt-injection-themed deception to mislead analysts and LLM-assisted triage tools. It maintains persistence via a LaunchAgent, communicates over the Telegram Bot API using AES-GCM over certificate-pinned TLS, resolves APIs at runtime to evade static analysis, and steals browser credentials, terminal histories, application listings, process snapshots, and the login keychain-db.
