TLDR; Из-за всяких неотображаемых символов юникода становится возможно закодировать произвольные данные в обычный смайлик (да и вообще в любой юникод символ). При этом закодированная часть не теряется даже при пересылке эмодзи!
Интересно, какой максимальной длины сообщение можно так передать? Можно ли так передать целый файл? 👀󠇀󠆒󠇁󠅻󠄐󠇁󠅷󠇁󠅲󠇀󠆮󠄐󠇁󠅲󠇁󠅳󠇁󠅲󠄐󠇁󠅱󠇀󠆠󠇀󠆬󠇁󠅻󠇀󠆩󠄐󠇀󠆫󠇁󠅾󠇀󠆡󠇀󠆮󠇀󠆯󠇁󠅻󠇁󠅲󠇀󠆭󠇁󠅻󠇀󠆩󠄯

Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels. Telegram boasts 500 million users, who share information individually and in groups in relative security. But Telegram's use as a one-way broadcast channel — which followers can join but not reply to — means content from inauthentic accounts can easily reach large, captive and eager audiences. The account, "War on Fakes," was created on February 24, the same day Russian President Vladimir Putin announced a "special military operation" and troops began invading Ukraine. The page is rife with disinformation, according to The Atlantic Council's Digital Forensic Research Lab, which studies digital extremism and published a report examining the channel. One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. In view of this, the regulator has cautioned investors not to rely on such investment tips / advice received through social media platforms. It has also said investors should exercise utmost caution while taking investment decisions while dealing in the securities market.
