The cybersecurity landscape is witnessing a significant uptick in Advanced Persistent Threats (APTs), with the latest threat emerging from an entity known as “Camaro Dragon.” Check Point researchers have tracked this Chinese state-backed group to a major cyber offensive, manipulating TP-Link routers with malicious firmware. The group’s modus operandi is strikingly similar to another cybercrime collective called “Mustang Panda,” suggesting a potential link between the two.
Unraveling Camaro Dragon’s game plan
Camaro Dragon’s attacks have specifically targeted organizations and individuals connected to European foreign policy. A significant overlap in tactics and infrastructure with Mustang Panda stands out. As of now, Check Point experts are investigating this intriguing phenomenon.
Key to Camaro Dragon’s stealthy operations is the “Horse Shell,” a custom backdoor inserted into TP-Link routers through malicious firmware. The backdoor equips the threat actors with a remote shell for executing commands on compromised devices, file transfer capabilities, and a mechanism for data exchange between two infected devices using the SOCKS5 protocol.
A masking mechanism
This malicious firmware allows the hackers to obfuscate their actual command and control center, using compromised devices as mere stepping stones towards their end goal. While the research team uncovered Horse Shell within the attacking infrastructure, they still face uncertainty. The real victims of this router implant remain undetermined.
The mystery extends to how these threat actors managed to implant the routers with the harmful firmware. Likely strategies include scanning the internet for recognized vulnerabilities or weak/default login credentials. Interestingly, TP-Link routers serve as the specific design target for the firmware components. However, they display an “agnostic” nature. This means they could potentially be reprogrammed to attack a wider range of devices and manufacturers.
Stepping up cyber defense
The revelation of Camaro Dragon’s router implant underscores the urgency of bolstering security measures to fend off such cyber onslaughts. Check Point Research suggests some practical measures to enhance security. First, they recommend keeping home and SOHO router software up-to-date. Secondly, altering the default credentials of devices is a crucial step. Finally, employing robust passwords, and whenever possible, implementing multi-factor authentication, adds another layer of security.
