ToyMaker Utilizes LAGTOY Malware to Facilitate Double Extortion Ransomware Attacks

TL;DR

Cybersecurity researchers have identified a financially motivated threat actor, ToyMaker, using custom malware LAGTOY to provide initial access to ransomware gangs like CACTUS for double extortion attacks.

Introduction

Cybersecurity researchers have recently shed light on the operations of an initial access broker (IAB) known as ToyMaker. This group has been observed facilitating access to double extortion ransomware gangs, notably CACTUS, by employing a custom malware called LAGTOY (also known as HOLERUN).

ToyMaker’s Operations

ToyMaker is assessed with medium confidence to be a financially motivated threat actor. Their modus operandi involves:

• Scanning for Vulnerabilities: ToyMaker actively scans for vulnerable systems that can be exploited.
• Deploying LAGTOY Malware: Once a vulnerable system is identified, ToyMaker deploys the LAGTOY malware to gain initial access.
• Selling Access: The group then sells this access to ransomware gangs like CACTUS, who use it to launch double extortion attacks.

LAGTOY is a versatile tool in ToyMaker’s arsenal, capable of evading detection and providing persistent access to compromised systems.

Double Extortion Tactics

Double extortion ransomware attacks involve not only encrypting the victim’s data but also exfiltrating it. Attackers threaten to leak the stolen data unless a ransom is paid, adding an extra layer of pressure on the victims.

Implications and Mitigation

The activities of ToyMaker highlight the growing trend of initial access brokers playing a crucial role in the ransomware ecosystem. Organizations need to be vigilant and implement robust security measures to protect against such threats.

Conclusion

The emergence of groups like ToyMaker underscores the evolving landscape of cyber threats. As initial access brokers continue to facilitate ransomware attacks, it is essential for organizations to stay informed and proactive in their cybersecurity strategies.
