How PLAYFULGHOST Infects Systems
PLAYFULGHOST uses multiple techniques to infiltrate devices. Here are the main methods:
- Phishing Campaigns: Users are tricked into opening malicious RAR archives disguised as harmless images. Once extracted, the malware installs PLAYFULGHOST.
- SEO Poisoning: Attackers mislead users into downloading compromised VPN installers like LetsVPN. These installers deploy interim payloads, eventually installing PLAYFULGHOST.
To evade detection, attackers use DLL hijacking and side-loading techniques, embedding malicious code into legitimate processes.
Powerful Features for Espionage and Sabotage
PLAYFULGHOST is highly stealthy and persistent. Its features include:
- Capturing keystrokes, screenshots, and audio.
- Collecting system and account data, including QQ and messaging profiles.
- Deleting clipboard content and browser caches for Chrome and Firefox.
- Blocking mouse and keyboard inputs to disrupt user control.
The malware also uses Mimikatz for stealing credentials and a rootkit to stay hidden. Additionally, it deploys the Terminator utility to disable security processes using vulnerable drivers.
Who Is Being Targeted?
PLAYFULGHOST focuses on Chinese-speaking Windows users. It leverages apps like QQ and LetsVPN, popular among this demographic. In related attacks, fake installers for Google Chrome were used to spread Gh0st RAT.
