The global telecom mesh Signal System 7 helps speech sound attack aircraft carrier across the world , including AT&T and Verizon , route call and text . It ’s also apparently perforate with certificate holes that allow hackers and spies hear to your call and record your text . It ’s so bad the ACLU ’s master engineer say me that people worried about being snoop should just not use their jail cell phone to make call . secrecy : Remember that ?
German research worker discoveredthat SS7 ’s outdated base establish it easy as hell to hack on , which can lead to huge invasion of secrecy , the Washington Post has reported . researcher will present their determination later this month at a conference in Hamburg . From the Post :
The flaw discovered by the German researchers are actually functions progress into SS7 for other aim – such as keeping calls colligate as users speed down main road , exchange from cell tower to cell tower – that hackers can repurpose for surveillance because of the lax security measures on the web .
Carriers like AT&T and Verizon use 3 guanine and 4 guanine networks for calls , content , and school text transport from people within the same connection , but they still call for to use old , icky , unsafe SS7 when they send datum across meshing . This means trace your phone and what you do on it is alarmingly simplefor the great unwashed in the know :
Those skilled at the numberless functions built into SS7 can site caller anywhere in the world , mind to vociferation as they fall out or record hundreds of encrypted birdsong and texts at a clip for later decryption . There also is potential to bunco users and cellular carriers by using SS7 functions , the researchers say .
SS7 ’s overall security measure suckiness is n’t a secret , though this fresh enquiry should draw tending to how important it is to overhaul the scheme . In August , the Post bring out a story highlightinghow society are already building surveillance systemscapable of stealth tracking using loophole in SS7 — and they ’re trade these organization to governments and individual groups .
One of the company , Verint , gasconade about service over 10,000 node on its website . Not mentioned : How many mass these clients offend .
So what can you do to obviate getting hacked or spy on by hoi polloi exploit the vulnerabilities of SS7 ? I asked the ACLU ’s principle technologist Christopher Soghoian :
“ Do n’t employ the phone service provide by the speech sound society for voice . The voice line they offer is not secure , ” he severalise me . “ If you require to make phone calls to loved one or colleagues and you want them to be safe , practice third - company tool . you’re able to use FaceTime , which is establish into any iPhone , or Signal , which you’re able to download from the app store . These allow you to have secure communicating on an insecure groove . ” For schoolbook , using third parties that provide end - to - end encryption also seals off your message from SS7 exploits .
So basically , your only line of defence is to not employ your phone as a blessed phone . It ’s an frail result , to put it mildly , to a trouble that will persist as long as this insecure system stay out-of-date . More than one thing is rotten in the state of telecom , but this crumbling global infrastructure is much putrid . [ The Washington Post ]
