Unlike traditional "sextortion" scams, which are often aggressive and transactional, the Crush Bug plays the long game. Attackers spend days or even weeks building a rapport with the victim, leveraging Telegram’s privacy-focused features to create a false sense of security.
Some platform crashes occur due to logical errors within the user interface. For instance, documented issues on the Telegram Desktop GitHub tracker reveal that desktop clients can crash when a user attempts to join a group using an invite link where the permission settings for "Send Messages" and "Send Media" are disabled simultaneously. The application fails to resolve the conflicting permissions UI, triggering an immediate shutdown. 🔍 Why Telegram Crashes: Technical Triggers Trigger Type Technical Root Cause Resulting Behavior Custom animated stickers lack strict file size boundaries.
: Bugs have been reported where switching video quality, playing "live photos" on certain Android devices, or attempting to draw outside image boundaries in the editor causes immediate app closure.
When Apple or Google rolls out major system updates (such as specific iterations of iOS or Android), older versions of the Telegram application may develop compatibility issues. Users frequently report loops where the app launches and crashes within a split second on startup due to unaligned system API mappings or missing device permissions. 4.

If your Telegram app keeps closing automatically because someone sent you a crush bug, do not panic. You can regain control of your account using these steps: 1. Use Telegram Web or Desktop
While crush bugs are usually text-based, similar exploits can be hidden in corrupted video or photo files. Disable auto-downloads in Settings > Data and Storage .
A vulnerability was identified where sending a specifically crafted string of Unicode characters (or a malformed .tgs animated sticker file) causes the Telegram client to enter an infinite loop or experience a buffer overflow, resulting in an immediate application crash. The "crush" occurs as soon as the message is rendered in the chat view, even without user interaction. For instance, documented issues on the Telegram Desktop
Crush bugs are annoying but generally a security breach—they don’t leak your messages or give control of your account. However, attackers sometimes use crush bugs as a distraction while attempting another exploit.
If you need to join high-risk groups (crypto airdrops, hacking forums, etc.), use a secondary Telegram account with no personal data. If it gets crushed, you lose nothing.
This write-up describes a hypothetical or recently discovered "crush bug" (a type of denial-of-service or application-hang bug) affecting Telegram clients. This is intended for educational purposes, bug bounty reporting, or security research documentation. : Bugs have been reported where switching video
The "crush bug" or app crash can stem from several factors, ranging from user-side data conflicts to server-side issues.
Operating systems and apps use complex shaping engines (like HarfBuzz or CoreText) to render diverse languages, emojis, and special symbols. A crush bug often strings together thousands of invisible characters, zero-width joiners, or right-to-left override tokens. When Telegram attempts to calculate how to display this text on your screen, the rendering engine runs out of memory or gets stuck in an infinite calculation loop, forcing the app to shut down. 2.
