A group of American university researchers have broken key 4G LTE protocols to generate fake messages, snoop on users, and forge user location data.
Those working on the coming 5G protocols should take note: the vulnerabilities are most worrying because they're written into the LTE protocols, and could therefore have an industry-wide impact.
Identified by Purdue University's Syed Rafiul Hussain, Shagufta Mehnaz and Elisa Bertino with the University of Iowa's Omar Chowdhury, the protocol procedures affected are:
- Attach – the procedure that associates a subscriber device with the network (for example, when you switch the phone on);
- Detach – occurs when you switch your device off, or if the network disconnects from the device (for example because of poor signal quality, or because the phone can't authenticate to the network); and
- Paging – this protocol is part of call setup, to force the device to re-acquire system information, and in emergency warning applications.
The researchers' paper (PDF) describes an attack tool called LTEInspector, which the researchers said found exploitable vulnerabilities that resulted in "10 new attacks and nine prior attacks” (detecting old vulnerabilities helped the researchers validate that the new vulns were genuine).

Language changes over time. His use of "vulns" is perfectly valid for the audience he is trying to reach. Though one might liken it to an adult trying to sound "cool / hip".

And it does so in three ways.
1. Someone or some group finds a clearer or more apt way to do a feature of language and it catches on. (example: English plurals with unmodified root plus -s or -es instead of changing the root to add -en, French ê in place of es) (N/A here)
2. Someone or some group starts doing a feature of language a merely different way and it catches on. (Example: modern English verb endings versus previous -eth endings, Latin American seseo vs. Spanish distinción with letters c, s, and z) (N/A here)
3. Someone or esp. some group isn't good at language, misuses it, and propagates the misuse. (Bingo.)
That #3 means that if enough people say that "up" means "down" then it becomes arguably so. They have already done this with "literally" being bastardized into "figuratively" and other wrongness-enshrined-by-idiots language changes.
It also means that if enough people misuse language (a large minority, or a majority) then the wrong becomes the new right. That doesn't mean that this is a good thing; it's just an undesirable side effect of 1. and 2. above. People who know the difference should at least mention it when it comes up. Changes destined to become the new standards will survive such mentions. "Vulns" totes will not, in all rational hope.
That use is arguably at least not completely invalid within that group, but this is not usage within that group; it's an article published to the wider world. Different group (security nerds+world at large vs. security nerds), different vocabulary (correct and standard vs. whatevs random crappy you wanna throw togethies.)

(you miss out on the vocal sound to capture the exact meaning, but . . .)
That's really baaaaaad, maaaaaan!
(then someone else uses two positive words to suggest agreement . . .)
Yeah, right.
