The "Crush Bug" in Telegram refers to a now-fixed vulnerability in the popular messaging app that could have allowed attackers to crash a user's device or even take control of it.
In July 2020, a security researcher discovered a bug in Telegram's messaging protocol. The bug, known as a "crush bug," was caused by a flaw in how Telegram handled certain types of messages. Specifically, when a user received a message with a specially crafted file or image, it could cause the app to crash.
The bug was particularly concerning because it could be triggered simply by receiving a message, without the user even needing to open it. This meant that an attacker could potentially send a malicious message to a user's Telegram account, causing the app to crash and potentially even allowing the attacker to gain control of the device.
Fortunately, Telegram's developers were quick to respond to the bug and released a patch to fix it. The fix was included in an update to the app, which users were encouraged to install as soon as possible.
The crush bug highlights the importance of keeping messaging apps and other software up to date, as vulnerabilities like this can have serious consequences if left unpatched. It also underscores the need for robust security measures in popular apps like Telegram, which is used by millions of people around the world. crush bug telegram

No. It only crashes the app. Your cloud data remains intact.
Telegram’s asynchronous nature means replies come unpredictably. A crush who replies instantly one day, but takes six hours the next, creates a variable reward schedule — the most addictive pattern for the human brain.

Some advanced crush bugs don’t crash the app once—they corrupt the local message database. Every time you reopen Telegram and it tries to sync that specific message, the app crashes again in an endless loop.
Real-world example (2023-2024): A known crush bug circulated in crypto trading groups. The message contained a single Arabic character followed by 2,000 invisible joining characters. Any Telegram user on Android v9.4.2 or below would see their app freeze and close immediately upon opening the chat.
