New Botnet Attacks Target Old D-Link Vulnerabilities

D-Link Devices Vulnerabilities Exploited by Mirai and Kaiten Botnets: A Growing Cybersecurity Concern

Recent reports highlight a troubling trend in cybersecurity: the exploitation of nearly decade-old vulnerabilities in D-Link devices’ Home Network Administration Protocol. Between October and November, these vulnerabilities have been used to distribute two significant botnets—FICORA, based on Mirai, and CAPSAICIN, based on Kaiten. This alarming development underscores the urgent need for enhanced security measures for network devices.

Cybersecurity experts from Fortinet’s FortiGuard Labs have analyzed these botnets, revealing that the FICORA botnet is capable of compromising numerous Linux architectures. It employs brute-force tactics and distributed denial-of-service (DDoS) attack capabilities, all while masking its malicious activities using ChaCha20 encryption. This sophisticated method poses a serious threat to network integrity.

Understanding the CAPSAICIN Botnet

The CAPSAICIN botnet, which saw heightened activity in late October, operates using hardcoded credentials to maintain control over compromised systems. Notably, it can terminate processes of competing botnets on targeted devices, demonstrating its aggressive nature.

Security Risks of End-of-Life Network Hardware

The emergence of these botnets brings to light the critical security risks associated with end-of-life network hardware. As these devices are no longer supported with updates, they become prime targets for cybercriminals. FortiGuard Labs emphasizes the necessity for enterprises to maintain regular updates and comprehensive monitoring of their device kernels to mitigate such risks.

Key Takeaways:

• Vulnerabilities in D-Link Devices: Older D-Link devices are being exploited by FICORA and CAPSAICIN botnets.
• FICORA Botnet: Utilizes brute-force attacks and DDoS capabilities, disguising activities with encryption.
• CAPSAICIN Botnet: Employs hardcoded credentials and can disable other botnets.
• Importance of Updates: Regular device updates and monitoring are crucial for cybersecurity.

For organizations relying on D-Link devices, the findings serve as a wake-up call. Ensuring device security through regular updates and vigilant monitoring can help prevent potential cyberattacks.
