Massive Data Breach Exposes 284 Million Accounts as Cybercriminals Shift to Telegram

A massive data breach has exposed 284 million compromised accounts from Telegram's 'ALIEN TXTBASE' channel, revealing a 1.5TB dataset with 23 billion rows of data. The breach, disclosed by Have I Been Pwned, highlights cybercriminals' shift from dark web marketplaces to mainstream platforms like Telegram. In response, HIBP has launched new API tools to help organizations proactively defend against credential-based attacks, while experts warn that the threat actor may resurface under a new identity despite announcing their intention to cease operations.
