A Walkthrough of the Ericsson Packet Core Controller (PCC) July 2026 Security Bulletin: From Denial of Service to Code Execution on MME, SGW-C, PGW-C, AMF, and SMF p1sec.com/blog/ericsson-…
We’ve just published our latest research on mobile core robustness under malformed signaling. It looks at how small deviations in signaling from UE or gNB perspectives can lead to crashes in core functions like AMF, SMF, and MME.
One malformed signaling message can crash core functions that are not directly exposed. Our latest write-up shows how stateful fuzzing exposes AMF, SMF, and MME crash paths across 5G and 4G. Proprietary does not mean fuzz tested. p1sec.com/blog/fuzzing-t…
🚨New research reveals how two sophisticated surveillance actors exploited the global telecom ecosystem and, for the first time, directly links combined 3G and 4G network attacks to mobile operator infrastructure. Full report 👇 citizenlab.ca/research/uncov…
Ever heard of a 5G SMF crash from an UE perspective? It exists, consider a malicious UE sending a malformed NAS SM message that will lead to a network outage. More on cve.p1sec.com
Open source drives telecom innovation. It also needs real protocol security testing. Our latest Ella Core findings are on cve.p1sec.com #TelecomSecurity #OpenSourceSecurity
🚨 Many telco vulns never get CVEs. Vendors delay, ignore, or silently patch. Operators? Left in the dark. At @p1security, we follow a 180-day disclosure policy—document and publish in our private VKB when silence persists. 🔗 p1sec.com/blog/responsib… #CVE #TelecomSecurity #VKB
Last month with @rj_gallagher we published an investigation into the shady SMS market and its implications for security. For those who want to go deeper @gabriels_geiger and I have written a more technical briefing medium.com/@lighthouserep…

Together with the paper: enck.org/pubs/bennett-c…. Nice research and results

As someone learning Erlang / Elixir for telecom applications, this is an interesting read about Ericsson's use (or lack) of the language they created. iknek.github.io/blog/the-erlan…
I recently found two very interesting Linux binaries uploaded to Virustotal. I call this malware 'GTPDOOR'. GTPDOOR is a 'magic/wakeup' packet backdoor that uses a novel C2 transport protocol: GTP (GPRS Tunnelling Protocol), silently listening on the GRX network (1/n) 🧵
1/11 Today, we’re releasing details of a small but interesting mobile #vulnerability called MMS Fingerprint, reportedly used by #NSOGroup. How this might work, and how we found it, is a bit unusual. enea.com/insights/dusti… @EneaAB @josephfcox @rj_gallagher @campuscodi @lorenzofb
Excellent document detailing the many location possibilities targeting mobile phones and modems. While the focus here is how handsets are tracked on the battlefield, most of the techniques described are known to be used quite generally, outside of any war context too.
(1/7) Today we issue our new report “Location Tracking on the Battlefield”. enea.com/insights/locat…. This is the first to comprehensively cover the different ways in which mobile devices can be vulnerable to #locationtracking in war. Report also features analysis of (condt)..
“A fix is long overdue for … the technical vulnerabilities at the heart of the world’s mobile communications networks.” @RonDeibert and Gary Miller from @citizenlab on the security deficiencies associated with cell phone “roaming.” lawfaremedia.org/article/when-y…
Opening Critical Infrastructure: The Current State of Open RAN Security trendmicro.com/en_us/research… #InfoSec #CyberSecurity #OpenRAN #Security
2 recent articles on mobile interconnect (citizenlab.ca/2023/10/findin…) and CDR (wired.com/story/hemisphe…), which show how much subscribers are exposed: good reads.
NEW REPORT: Finding YouThe Network Effect of Telecommunications Vulnerabilities for Location Disclosure 👇 citizenlab.ca/2023/10/findin…
A year ago we revealed how Italian surveillance company Tykelab was using phone networks in the Pacific for global tracking operations. Our friends at @occrp have an update occrp.org/en/daily/17987…
Android 14 introduces first-of-its-kind cellular connectivity security features #MobileSecurity #AndroidSecurity by @Google security.googleblog.com/2023/08/androi…
Serious findings ! The list of critical vulns in the Exynos baseband published in the last Android bulletin is quite long after all: source.android.com/docs/security/…. I guess the Internet-to-baseband vulns relate to IKEv2/IPsec.
What happens when you get @natashenka, @ifsecure, @_fel1x, @i41nbeer and @tehjh working collaboratively on a new attack surface for the team? This: googleprojectzero.blogspot.com/2023/03/multip… The blogpost also includes actions that users can take to protect themselves while waiting for patches.
