security alert:

we're currently seeing a wave of compromised accounts sharing malicious telegram links to groups and via DMs. the malicious channel in question (or one of them) is pictured above.

when a user requests to join the channel, they will receive a direct message from a "verification" bot, purporting to be an anti-bot measure. This bot requests that the user shares their phone number, at which point it will attempt to log into telegram with that number, prompting telegram to send a confirmation code to the account owner. at this point, the bot prompts the user to enter the confirmation code using an inline keyboard, bypassing a critical telegram safety mechanism that invalidates login codes if they are typed into a message. if the user complies, their account is compromised and the malicious actors can use it for anything they want.

DO NOT click on any telegram links that you didn't ask for, especially ones that are sent with no context, even if it comes from someone you trust.
