P1 Security

Join us for TelcoSec Talk #2, with @philpraxis and @hkashfi as we map the Iran-linked APT ecosystem. We’re connecting technical signals and infrastructure to see the full picture. Tomorrow 11am CET. 🛡️ Register: watch.getcontrast.io/register/p1-se… #CyberSecurity #APT #ThreatIntel #war

Next week: TelcoSec Talk #2 with Philippe Langlois and Hamid Kashfi on the Iran cyber threat landscape, using ApexThreats. Register: watch.getcontrast.io/register/p1-se… #CyberThreatIntelligence #TelecomSecurity #ThreatIntelligence #CyberSecurity #APT #Iran #TelcoSec #P1Security

MWC is done. The badge is off. The conversations are not. What stood out most? Telecom security is a real operational priority. If we missed you at MWC, let’s continue the discussion: contact@p1sec.com #MWC26 #TelecomSecurity #5GSecurity #CyberSecurity #P1Security

P1 Security will be part of the Online [un]prompted conference this week. Philippe Langlois, our founder and CEO, will moderate a lunchtime Zoom chat session titled: Defense and Offense of Critical Infrastructure in the Age of AI Contact: contact@p1sec.com #AISecurity

“Open it temporarily so it works” is how 5G networks get permanently exposed. “No firewall matrix, no traffic flow visibility, so people open the network until things work… then leave it like it is.” Recording: watch.getcontrast.io/register/p1-se… #5GSecurity #TelecomSecurity #ZeroTrust

SMS blasters = high volume spam or fraud. At #MWC2026 in Barcelona, we’re bringing a fun SMS Blaster Detector experiment. Let’s meet: p1sec.com/mwc-2026

Less than a month left until MWC Barcelona 2026. This year is going to be interesting. We have some exciting things lined up, and the team will be on site. Come meet us at Block 5B41, Stand 13. Drop by the booth, or book a meeting in advance: p1sec.com/mwc-2026 #MWC26

The Physical to 5g core compromise Webinar is going live now - mailchi.mp/p1sec/webinar-…

Physical access is not “local only”. In many environments it can become a network foothold, then pivot via the management plane, weak segmentation, insecure remote access, or stolen creds until the 5G core is reachable.Register: watch.getcontrast.io/register/p1-se…

What red teams keep finding in 5G core environments - mailchi.mp/p1sec/webinar-…

How does physical exposure translate into risk for mobile critical infrastructure, and how can teams reduce it without slowing operations down? Physical to 5G Core Compromise Red team lessons learned + practical takeaways Register: watch.getcontrast.io/register/p1-se…

Most operators arrive at MWC asking how exposed they really are. In 45 minutes we map your attack surface and define a realistic 2026 reduction plan. Meet us: p1sec.com/mwc-2026

2025 telecom attacks delivered a clear lesson. The SK Telecom case shows that without basic controls like segmentation, hardening, and detection, impact follows. Full talk: watch.getcontrast.io/register/p1-se…

Telecom security is not about finding risks. It is about explaining them to the business. The Telco Attack Surface Matrix helps MNOs structure exposure and justify security investment. telcoasm.p1sec.com

Closing the year with the same priority as always: securing mobile networks at global scale. Wishing everyone a bright, resilient, and secure New Year.

Default passwords are not the debate in 5G. Ownership is. Vendors assume cleanup. Operators assume it is done. That gap leaves real creds live in production. Full talk: watch.getcontrast.io/register/p1-se…

Reverse engineering is regulated, not a gray area. This paper explains when it is legal across regions and how it applies to telecom security. Read: p1sec.com/white-paper/re…

Regulatory disclosure changed telecom security. Public incident reporting confirms a hard truth: telecom flaws are actively exploited by persistent attackers targeting critical infrastructure. Full talk: watch.getcontrast.io/register/p1-se…

5G security becomes clear once you map what actually breaks in real pentests. Weak authentication, remote code execution in microservices, privilege escalation in Kubernetes, SSRF and DoS on the SBI all show up again and again. What would you add to the mitigation layer?

We released the Telco Attack Surface Matrix to help teams visualise exposure across RAN, Core, IMS, signalling and more. Try it and share your feedback so we can improve it. telcoasm.p1sec.com #telcosec
