Angry Birds: Toy Ghouls’ new toys

Securelist
Actively Exploited

Overview

Kaspersky's GERT team has identified new backdoors linked to the hacking group known as Toy Ghouls. These backdoors utilize two distinct methods for command-and-control: one operates through the HiveMQ MQTT broker, while the other employs the Matrix-based Element messenger. This discovery raises alarms as it indicates the group's ongoing efforts to establish secure communication channels for their malicious activities. The use of these platforms suggests that the attackers may be adapting their techniques to evade detection, which could pose significant risks to organizations relying on these technologies. Understanding and mitigating this threat is crucial for enhancing cybersecurity measures against such evolving tactics.

Key Takeaways
