The Federal Communications Fee is lastly minded to handle decades-old vulnerabilities.
Dusty, moldy, prehistoric protocols from the Nineteen Eighties and ’90s nonetheless underpin our cellphone networks. Filled with safety holes, they permit scrotes to trace our areas—whether or not cellular or wired (ask your dad and mom). The FCC is asking the trade to do one thing about it.
We’ve identified concerning the issues because the mid-Nineties. In right now’s SB Blogwatch, we ask, “Why now?”
Your humble weblogwatcher curated these bloggy bits in your entertainment. To not point out: Steamed Hams, but it surely’s Netflix.
Quick Sufficient for Authorities Work
What’s the craic? Suzanne Smalley stories, FCC to probe ‘grave’ weaknesses in cellphone community infrastructure:
“Vital position”
The … FCC says it’s taking motion to handle important weaknesses in telecommunications networks that may allow cybercrime and spying. The company is investigating how vulnerabilities within the protocols Signaling System No. 7 (SS7) and Diameter … permit breaches, significantly by revealing customers’ areas to malicious hackers and spies.
…
The fee’s Public Security and Homeland Safety Bureau is spearheading the hassle. The FCC mentioned … SS7 and Diameter play a “important position” in U.S. telecommunications infrastructure [and] it needs to make sure the protocols’ vulnerabilities can’t permit hackers to “observe” customers’ areas.

“Safety countermeasures”
Over the past a number of years, quite a few stories have referred to as consideration to safety vulnerabilities current inside SS7 networks and recommend that attackers goal SS7 to acquire subscribers’ location info. … The Diameter protocol gives the identical providers as SS7 and consequently presents related vulnerabilities. [The] protocols are nonetheless the inspiration for cellular phone networks, particularly for roaming capabilities.
…
The Bureau finds you will need to extra particularly study the realm of location monitoring. To that finish, the Bureau seeks renewed public remark, together with from communications service professionalviders, … on the implementation and effectiveness of safety countermeasures … with respect to location monitoring.
Wait. Pause. “Over the past a number of years”? I really feel like we’ve been speaking about this for many years. Why now? A number of weeks in the past, Ryan Gallagher wrote, Senator Calls for Overhaul of Telecom Safety:
“Trick the cellphone community”
Overseas governments are abusing safety flaws in cell phone networks to secretly observe Individuals within the US and journalists and dissidents overseas, Senator Ron Wyden has warned. In a letter despatched to President Joe Biden … Wyden [D-OR] is urging the White Home to counter the risk by supporting a serious overhaul of cybersecurity requirements.
…
On the heart of the senator’s concern is an obscure telecom protocol referred to as SS7, [which] is used to route communications between cellphone networks. SS7 incorporates identified safety vulnerabilities that governments and personal surveillance firms have exploited. … It may be used to trick the cellphone community itself into handing over communications or location info from a selected cellphone. A number of firms at the moment are offering international governments with these “cellphone firm hacking providers,” in response to Wyden, [who] accuses CISA of “actively hiding info” about the issue.
Why didn’t the requirements our bodies do one thing? This Nameless Coward has a protracted reminiscence:
Again [in] 1994/95, … I used to be engaged on a system to watch and handle SS7 networks. [We] found holes within the SS7 protocol.
…
The ITU didn’t need to know, so we shut up and principally went to work in different industries. It was a catastrophe ready to occur as soon as PC CPU speeds [improved]. Then the latency of the SS7 community could possibly be exploited by a hacker to inject packets and even shut down a hyperlink.
Today it’s a lot simpler.
Straightforward? Actually, although? What’s the issue? ronsor neatly boils it down:
There are insecure SS7 nodes uncovered to the Web. I’ve seen them earlier than.
Yikes. The FCC had higher repair it—and quick. satsuke calls {that a} “tall order”:
I used to be an SS7 community engineer for 20 years. The issue will take a lot [more] than a couple of federal inquiries, as a result of SS7 was constructed with nearly no safety. … Within the Nineteen Seventies, the one organizations that would discuss on an SS7 community have been different SS7 suppliers—particularly giant telcos and a few companies.
…
Diameter is healthier … but it surely’s nonetheless largely unencrypted. … There’s functionally no barrier to entry and telcos are obliged to interconnect on a non-preferential foundation to forestall the fracturing of the phone system (e.g., if Verizon determined to not interconnect a competitor’s clients).
Seems like a difficult downside. Kevin McMurtrie attracts comparisons with 5G/NR:
Sooner — sure!
mmWave loopy quick — sure!
Edge compute energy — OK, certain!
AI, robots, WFH surgeons — why not?
Unicorns — higher imagine it!
Repair legacy telco safety — whoa, let’s be life like.
In the meantime, sounding barely cynical, M0nkge thinks it’s “not wanted anymore”:
This similar flaw exists in international networks. Now that the US Intel businesses have a workaround, they gave the OK to repair it.
And Lastly:
No, Mom. It’s Simply the Northern Lights
