Binance does have a legitimate desktop app, although I’m not sure why anybody would use it instead of the website. They don’t provide a signature for their official desktop apps so people could end up in a situation where they do a google search for "Binance desktop app" and accidentally end up on a phishing site and won’t know they are installing malware until it is too late.
What may shock many of us is that fake app makers are successful in trapping victims even though their method may seem primitive and no one would believe it. Launching a fake app in parallel with an advertising campaign can achieve good results for hackers. Here we can address Binance’s responsibility to contribute to achieving a large part of the security of its users by being aware of these fake apps or malicious links to publish warnings about them on its channels and alerting users. This may seem pointless, but it certainly has a direct impact and can contribute to reducing the damage that these attempts may cause.
