Security hole could let hackers take over Juniper Networks PTX core routers
CSO Online 27.02.2026 21:36
Network admins with Juniper PTX series routers in their environments are being warned to patch immediately, because a newly-discovered critical vulnerability could lead to an unauthenticated threat actor running code with root privileges.
The hole is “especially dangerous, because these devices often sit in the middle of the network, not on the fringes,” said Piyush Sharma, CEO of Tuskira. “If an attacker gains control of a PTX, the impact is bigger than a single device compromise because it can become a traffic vantage point and a control point at the same time. This opens the door to the stealthy interception of data flows, controller redirected traffic, or easy pivots into adjacent networks.”

Ransomware attackers are switching tactics in favor of more stealthy infiltration, as the threat of public exposure of sensitive corporate data is becoming the main mechanism of extortion.
Picus Security’s annual red-teaming report shows attackers shifting away from loud disruption toward quiet, long-term access — or from “predatory” smash-and-grab tactics to “parasitic” silent residency.
