📡 IMS and SIP: The Brains Behind Telecom Services — and Prime Targets for Attackers

Modern telecom systems rely heavily on IMS and SIP to deliver multimedia services across prepaid and postpaid platforms. But with great flexibility comes major exposure:

⚠️ SIP spoofing, session hijacking

⚠️ IMS DoS and third-party app vulnerabilities

⚠️ Weak authentication and interception risks

In our blog post, we break down:

🔍 How IMS and SIP actually work

🔍 Where the most critical vulnerabilities lie

🔍 How telcos can reinforce their infrastructure — both technically and operationally

🚨 Why Responsible Disclosure in Telecom Still Fails – And How P1 Security Acts

Many telco vulnerabilities never make it into public CVEs. Vendors delay, ignore, or quietly patch—without alerting operators. Meanwhile, critical infrastructure stays exposed.

At P1 Security, our process doesn’t wait in silence:

🔍 We research, pen-test, and notify both clients and vendors
⏳ We follow a 180-day disclosure window (double the standard)
🧠 When vendors remain silent, we document and publish responsibly in our Vulnerability Knowledge Base
📣 Clients are always informed and can assess their risk

Transparency isn’t optional in telecom—it’s a necessity.

🎥 What is O-RAN, really?

O-RAN isn't just a buzzword — it's a structural shift in how we build radio access networks.

By moving away from proprietary, locked-in systems and toward open, cloud-native architectures, operators gain flexibility… but also inherit new risks.

At the beginning of this analysis, we lay the groundwork — defining what O-RAN is before unpacking the security implications throughout the session.

Last week, P1 Security was at MWC Barcelona, connecting with industry leaders to discuss the latest in mobile network security. From #5G vulnerabilities to #AI driven cyber threats, the conversations emphasized the need for advanced attack surface management, intrusion detection, and threat intelligence solutions.

🙏 A special thank you to Business France for their incredible support and organization throughout the event.

A huge thank you to our #partners, #customers, and industry #peers who joined us to exchange insights and drive innovation in telecom security. Looking forward to what’s next!
