Signaling System vii (SS7) that could allow hackers to head inward soul telephone calls as well as read text messages on a potentially vast scale, despite the virtually advanced encryption used yesteryear cellular networks.
Despite fixes beingness available for years, the global cellular networks induce got consistently been ignoring this serious issue, maxim that the exploitation of the SS7 weaknesses requires pregnant technical as well as fiscal investment, thence is a real depression risk for people.
However, before this twelvemonth nosotros saw a real-world attacks, hackers utilised this designing flaw inward SS7 to drain victims' depository fiscal establishment accounts yesteryear intercepting two-factor authentication code (one-time passcode, or OTP) sent yesteryear banks to their customers as well as redirecting it to themselves.
If that incident wasn't plenty for the global telecoms networks to reckon fixing the flaws, white chapeau hackers from Positive Technologies at nowadays demonstrated how cybercriminals could exploit the SS7 flaw to induce got command of the online bitcoin wallets to pocket all your funds.
Created inward the 1980s, SS7 is a telephony signalling protocol that powers over 800 telecom operators across the world, including AT&T as well as Verizon, to interconnect as well as telephone substitution data, similar routing calls as well as texts amongst ane another, enabling roaming as well as other services.
Just similar inward previous SS7 hacks, the Positive researchers were able to intercept the SMS messages containing the 2FA code yesteryear exploiting known designing flaws inward SS7 as well as gain access to the Gmail inbox.
From there, the researchers went straightaway to the Coinbase concern human relationship that was registered amongst the compromised Gmail concern human relationship as well as initiated about other password reset, this time, for the victim's Coinbase wallet. They thence logged into the wallet as well as emptied it of crypto-cash.
Fortunately, this assault was carried out yesteryear safety researchers rather than cybercriminals, thence at that topographic point wasn't whatever actual fraud of bitcoin cryptocurrencies.
This termination looks similar a vulnerability inward Coinbase, but it's not. The existent weakness resides inward the cellular organisation itself.
Positive Technologies has besides posted a proof-of-concept video, demonstrating how slowly it is to hack into a bitcoin wallet simply yesteryear intercepting text messages inward transit.
This assault is non express to exclusively cryptocurrency wallets. Any service, live on it Facebook or Gmail, that relies on two-step verification are vulnerable to the attacks.
The designing flaws inward SS7 induce got been inward circulation since 2014 when a squad of researchers at High German Security Research Labs alerted the basis to it.
The flaws could allow hackers to head to telephone calls as well as intercept text messages on a potentially massive scale, despite the virtually advanced encryption used yesteryear cellular network operators.
Last year, the researchers from Positive Technologies besides gave demonstrations on the WhatsApp, Telegram, as well as Facebook hacks using the same designing flaws inward SS7 to bypass two-factor authentication used yesteryear those services.
At TV programme threescore Minutes, Karsten Nohl of High German Security Research Labs concluding twelvemonth demonstrated the SS7 assault on the United States Congressman Ted Lieu's telephone number (with his permission) as well as successfully intercepted his iPhone, recorded call, as well as tracked his precise place inward real-time simply yesteryear using his prison theatre cellular telephone telephone number as well as access to an SS7 network.
Although the network operators are unable to piece the issues anytime soon, there's piddling a smartphone user tin give the sack do.
Avoid using two-factor authentication via SMS texts for receiving OTP codes. Instead, rely on cryptographically-based safety keys every bit a minute authentication factor.

Here's How Hackers Hacked into Bitcoin Wallet as well as Stole Fund
While demonstrating the attack, the Positive researchers starting fourth dimension obtained Gmail address as well as telephone number of the target, as well as thence initiated a password reset asking for the account, which involved sending a onetime say-so token to live on sent to the target's telephone number.Just similar inward previous SS7 hacks, the Positive researchers were able to intercept the SMS messages containing the 2FA code yesteryear exploiting known designing flaws inward SS7 as well as gain access to the Gmail inbox.
