“Equipped with these pieces of information, there are a number of methods that can be called from the Telegram Bot API. In our case, the forwardMessage() method is particularly useful, as it allows any message from any chat a given bot has access to be forwarded to an arbitrary Telegram user. To do this we need the API token and the ‘source’ chat_id (either extracted from previous messages sent by the bot or, in the case of malware, from the binary itself) – along with the ‘target’ chat_id (which is our own user id) and finally the message id we would like to forward.”

-------Story of Sim Jacking-------------
In February, T-Mobile sent a mass text warning customers of an “industry-wide” threat. Criminals, the company said, are increasingly utilizing a technique called “port out scam” to target and steal people’s phone numbers. The scam, also known as SIM swapping or SIM hijacking, is simple but tremendously effective.

First, criminals call a cell phone carrier’s tech support number pretending to be their target. They explain to the company’s employee that they “lost” their SIM card, requesting their phone number be transferred, or ported, to a new SIM card that the hackers themselves already own. With a bit of social engineering—perhaps by providing the victim’s Social Security Number or home address (which is often available from one of the many data breaches that have happened in the last few years)—the criminals convince the employee that they really are who they claim to be, at which point the employee ports the phone number to the new SIM card.

Game over.

“With someone's phone number,” a hacker who does SIM swapping told me, “you can get into every account they own within minutes and they can't do anything about it.”
