Be cautious when third-party apps request entry to social media accounts. I’ve had my very own personal experience of my Twitter account being exploited by hackers by way of a rogue third-party service.

Trezor says that it revoked all lively periods (kicking out anybody with entry to the Twitter account) in addition to deleting the unauthorised posts, and prevented additional entry by revoking third-party apps.

This is not the primary time {that a} phishing rip-off has made the rounds, duping corporations into clicking on faux Calendly hyperlinks.

As an example, in January The Verge reported {that a} scammer had posed as one in all its journalists and pretended to be utilizing Calendly to schedule interviews with targets – all as a way to drain cryptocurrency wallets.

In the identical month, a scammer posed as one other journalist and efficiently tricked blockchain safety outfit CertiK into believing they had been scheduling a gathering by way of Calendly. The scammer then succeeded in seizing control of the firm’s Twitter account to put up a malicious hyperlink.

Sadly, it is not the primary time that Trezor has fallen foul of cybercriminals.
