Cybersecurity experts have uncovered a Chinese-backed hacking campaign targeting end-of-life Juniper MX routers with six custom backdoors for stealthy access. These UNC3886 attacks allow cybercriminals to execute remote commands, steal data, and bypass security controls.

Attackers use TinyShell malware to exploit Juniper’s security loopholes. Six backdoors enable file transfers, remote shells & log manipulation.

No official patch – replace EoL routers & update security measures! update firmware, enable MFA, and follow Juniper’s security advisories.
