Urgent Cybersecurity Threat: Cleaning Up Routers Infected by Russia’s APT28 Hacker Group (Moobot Malware)

In recent developments, the US government has taken significant action to combat the cyberespionage efforts of the Russian APT28 hacker group, also known as Fancy Bear or Sednit. This group, which has been linked to numerous high-profile cyberattacks, recently launched an attack that involved infecting routers with a malware called Moobot. This attack specifically targeted small office/home office (SOHO) routers and is a reminder of the dangers posed by unsecured network infrastructure. Here, we break down the details of the Moobot malware attack, offer a comprehensive removal guide, and provide preventive methods for avoiding future infections.

Details of the Moobot Malware Attack

The Moobot malware, which was used by APT28, compromised a botnet of Ubiquiti routers primarily used in SOHO environments. These routers were infected by exploiting default credentials and a trojanized OpenSSH server. Once inside the routers, APT28 actors took control of the devices, utilizing them for a variety of covert activities aimed at sensitive sectors across the globe. Below is a summary table of the details of this attack:

Category	Details
Threat Type	Malware (Moobot), Cyberespionage
Detection Names	“Moobot”, “APT28”, “Fancy Bear”, “Sednit”
Symptoms of Infection	– Slow internet speeds
	– Unusual router activity or settings
	– Sudden changes in router configurations
Damage	– Compromise of sensitive data
	– Unauthorized access to targeted systems
	– Deployment of further malicious payloads
Distribution Methods	– Exploitation of default credentials
	– Trojanized OpenSSH server processes
Danger Level	High (Cyber espionage, potential for massive data breaches and system infiltration)

APT28’s sophisticated tactics included exploiting zero-day vulnerabilities, leveraging the compromised routers for command-and-control (C2) infrastructure, and deploying custom backdoors like MasePie. This backdoor was designed to establish reverse proxy connections and SSH tunnels, which made it difficult to detect and remove the malware.

Preventive Methods to Avoid Future Infections

Preventing future infections is crucial, especially given the ongoing nature of cyberespionage activities by APT28. Below are key preventive measures to safeguard your network and devices from similar threats:

Use Strong, Unique Passwords

Ensure that all devices on your network, including routers and IoT devices, are secured with strong, unique passwords. Avoid using default login credentials and employ a password manager to generate and store complex passwords.

Enable Multi-Factor Authentication (MFA)

Enable MFA wherever possible, especially for accounts with administrative access. This adds an additional layer of protection by requiring a second form of verification.

Update Firmware and Software Regularly

Keep your router’s firmware and any software on your devices up to date. Regularly check for updates and apply security patches to minimize vulnerabilities that could be exploited by attackers.

Disable Remote Access

Disable remote management features on your router unless absolutely necessary. This reduces the risk of external attackers gaining control over your router.

Install Security Software

Utilize comprehensive anti-malware software, such as SpyHunter, to provide continuous protection against a wide range of threats. Regularly update your security software to ensure it can detect the latest threats.

Monitor Network Traffic

Regularly monitor the traffic on your network for any unusual activity. If you notice an increase in traffic or unfamiliar devices connected to your network, investigate the issue immediately.
