Смысл: The main idea is that Telegram and WhatsApp accounts can be compromised by exploiting vulnerabilities in the SS7 telecommunications protocol to intercept SMS verification codes, proving that such attacks are possible for skilled actors and not just intelligence agencies.
Researchers demonstrate that Telegram and WhatsApp accounts can be hacked by exploiting SS7 network vulnerabilities to intercept SMS activation codes.
Смысл: The text explains how attackers use Telegram IDs and OSINT tools to find phone numbers and then exploit insecure web forms to perform costly and disruptive SMS-bombing attacks on users.
Attackers are using Telegram user IDs and OSINT databases to identify phone numbers and then leveraging vulnerable website registration forms to launch SMS-bombing attacks on chat participants.
Смысл: The main idea is that Telegram employs different authentication workflows based on geography, and in certain 'expensive SMS' regions, email compromise can lead to full account takeover because the mandatory SMS step is bypassed.
In certain geographical regions, Telegram's reduced reliance on SMS verification means a compromised email can lead to a total account takeover.
