How hacker can access your bitcoin wallet
How Hacker Can Empty Ur Bitcoin Wallet Using Ur Phone no & Email
Security
of SMS-based two-factor authentication has been long-debated. Despite
flaws in Signalling System No. 7 (SS7), which is an internationally used
telec
om protocol to route texts and calls, it continues to be used at a
large scale in banking and other services.
The security
researchers Positive Technologies have shown how a bitcoin wallet can be
hacked using SS7 vulnerabilities. By getting their hands on SS7
network, the hackers were able to reset the Gmail passwords using
SMS-based two-factor authentication.
A big flaw in SMS-based 2FA
is that the one-time password can be accessed on a variety of devices
and services, which might have their own flaws. Thus, the attack surface
increases. On the other hand, the true 2FA, which is like a push
notification popup, sends the verification prompt to one device.
In
a video posted by the researchers, which is embedded below, it’s shown
how easy it is to carry out the attack. By intercepting the text
messages in transit, the hackers can take control of your Gmail account
and any other service associated with it.
Not just cryptocurrency
wallets, this flaw puts your banking and social media accounts at risk.
“This hack would work for any resource – real currency or virtual
currency – that uses SMS for password recovery,” the researchers told
Forbes.
Getting access to the SS7 network is the biggest barrier
one needs to cross. The cybercriminals can buy the access on the dark
web. In the past, at least at one occasion, SS7 was used to empty bank
accounts. According to Forbes, many surveillance companies are also
selling services to spy using SS7 flaw.
What should the user do?
As
stressed earlier, SS7 flaw has been known to the telecom industry from a
long time. So, unless they don’t take steps to make it more secure, the
users need to take steps on their own. You can use tools like Google
Authenticator, Google prompt, or security key for extra security.
