Right now, NFTs are all the rage. Everyone is talking about them, and many are excited about them. Hackers have been quick to take advantage of that fact, and the Fortinet researchers have stumbled across a poisoned spreadsheet that purports to contain information about NFTs.
The spreadsheet actually quietly deploys a malware strain called BitRAT when opened.
BitRAT is a particularly nasty strain of malware that first appeared for sale on the Dark Web back in late 2020. It is notable because it can bypass User Account Control (UAC), which is a Windows feature designed to prevent unauthorized access to the OS.
Once installed on a target system BitRAT can steal login credentials from browsers and other applications. It can log keystrokes and upload or download files which makes it more than capable of installing other forms of malware once the beachhead has been established.
It's too early to say yet whether NFTs are here to stay or if they're just a flash in the blockchain pan. Either way, if they are generating buzz and excitement around the world, hackers will continue to exploit that excitement.
As the Fortinet researchers put it:
"Be mindful that attackers often use attractive and trendy subjects as lures. As NFTs become increasingly popular, they will be used to entice victims into opening malicious files or clicking on malicious links."
The best thing you can do is to educate your employees and inform them of the threat. Remind everyone you know that no matter how exciting the topic might be, it's never a good idea to open files from untrusted sources or click on links embedded in emails. If you need to go to a website open a new browser tab and manually type in the URL. Better safe than sorry.
