Chinese espionage group UNC3886 has been exploiting a vulnerability in Juniper Networks routers using their Junos OS, which is based on FreeBSD. The compromised routers were outdated and running end-of-life hardware and software, leading to significant risks for organizations in sectors like defense and telecommunications. Though a patch was issued, Mandiant, collaborating with Juniper, revealed that a notable number of devices were impacted, but there's currently no evidence of data exfiltration. The situation underscores the vulnerability of critical infrastructure to cyber threats from state-sponsored actors.
Chinese spies exploited vulnerabilities in outdated Juniper Networks routers, gaining root access to devices through custom backdoors, posing risks to multiple organizations.
