Telegram Passport is the most up-to-date aspect introduced by the messaging app final month. It lets users to add personalized identification files these types of as passports, id cards, and motorists licenses to be saved in the Telegram cloud. These files are encrypted so that users can validate their identities on 3rd-social gathering products and services with out exposing their personalized info.
Virgil, however, thinks that this aspect is not safe at all.
First of all, Telegram uses Secure Hashing Algorithm 2 (SHA-512), which is cryptographically weak. Virgil describes that in order to safe passwords, it ought to get a hacker more time to guess every single password.
“It’s 2018 and one particular major-stage GPU can brute-power examine about 1.5 billion SHA-512 hashes for each second.”
Salting is a way to include random info in a password , however, even that will not support in SHA-512’s circumstance. Only a potent password will keep a users’ account protected from brute power attacks.
Virgil added that employment products and services website LinkedIn was hacked in 2012 considering that it applied SHA-2’s predecessor, SHA-1. The attack uncovered the passwords of 8 million LinkedIn users. Upcoming year, on line marketplace LivingSocial, which also applied SHA-1, missing 50 million passwords in a identical attack. Hence, it is surprising that Telegram made the decision to use these types of a weak password security program.
Secondly, Telegram claims that it encrypts user info and then sends it to the cloud. The info is then decrypted and re-encrypted to affirm the user’s id on the 3rd-social gathering provider. The info attained is not totally random and utilizes SHA-2 when again. In addition to that, the app doesn’t include the possibility of a digital signature, and “the absence of digital signature lets your info to be modified with out you or the receiver currently being equipped to notify.”
On its official weblog article, Telegram wrote that the provider was conclude-to-conclude encrypted and applied a password only the user understood. However, this research clearly show that the loopholes current in the codes makes the user susceptible to hackers. Some of the alternate options supplied by Virgil include SCrypt, BCrypt, Argon2, BrainKey and Pythia.
In August 2016, hackers uncovered the cell phone figures of 15 million Iranian Telegram users. Back then, a user authentication program that applied SMS to complete the course of action resulted in the attack. Considering the fact that Passport holds sensitive info, it might now be qualified by hackers. It is now up to Telegram to tackle the situation and improve the protection of this “high profile product”.
