Interesting links, week 50, 2023

Interesting telco/tech news for this week:

• Telefónica Innovación Digital: [ES] in Spanish. A summary of the 10 years of history of innovation-centric orgs in Telefonica, in the wake of the new org named “Telefónica Innovación Digital”. I joined them as Telefonica I+D employee in 2011 during the birth of Telefonica Digital, so the new name sounded quite familiar.
• How to Kill a Decentralised Network: Ploum is relating the events around Google and the XMPP federation, and how the standard was quite affected by the encounter. I remembered vividly fighting to keep the connection with Google users with my XMPP server, until I dropped everything. I still keep my SMTP server online though. Mastodon destiny might be very different.
• 5Ghoul: some research work on 4G/5G vulnerabilities on the NAS messages parsing from UE/CPE using B210 SDR.

Found a couple of nice links this week on the Internet:

• Bug Fix - Cloud Access Misconfiguration: a security incident plagged the control plane of some network product - leading to one group of user having access to the instances of others users.
• mastodon’s post: couple of relevant comments - both twoot and blog posted linked to it - to the Google/Epic case.
• Looking closer at the syslog: long and detailed post on syslog, in the context of implementing it on PostmarketOS.
