Binance customer service representative Sisi disclosed a new type of scam on platform X and reminded everyone to pay attention to fund security. A user complained that they were scammed out of money by a "Binance executive" who promised to help solve a problem, but after the money was transferred, there was no further communication.Upon further investigation, several red flags were discovered: first, the scam was very simple; the chat screenshots and transfer records provided by the user showed that the "executive" did not verify any details, yet the user "absolutely trusted" them and transferred the money directly; second, the transfer records were suspicious, as the address claimed by the user to be the scam address was likely their own; third, the chat records "disappeared," and the user claimed that the other party had activated privacy mode, only able to provide screenshots of "post-questioning"; fourth, the account the user questioned was that of a real executive, but the executive was unaware of the situation.After the investigation, it was revealed that this was a self-directed scam targeting Binance and its users. The user fabricated chat records and transfer records (using a certain guarantee platform for the transfer records), then falsely claimed that the chat records were deleted, and later questioned the real executive's account, creating two sets of "executive" screenshots. Then, they approached customer service with the real executive's chat records, requesting verification, attempting to induce a response from customer service, and threatening to apply pressure through social media if assistance was not provided.Sisi stated that the purpose of sharing this publicly is to raise awareness and prevent various new types of scams. They also warned scammers and speculators that actions attempting to frame Binance through forgery and deception will be firmly exposed and legally pursued. Binance reminds users that the platform will not proactively contact users through unofficial channels, nor will it ask users to transfer funds or pay any fees to designated addresses.
