Twitter has started to transition from the previous ‘twitter.com’ domain to ‘x.com’, but threat actors are utilising this change to spin up phishing infrastructure and take advantage of a flaw.

In the past week, X (formally Twitter) have started transitioning away from the historic twitter.com domain towards the new x.com.

In doing so, the Twitter platform is changing links mentioning twitter.com to read x.com instead. But threat actors have started to abuse this feature and new domains are being created likely for phishing.

Between April 8-10, over 60 domains were registered to take advantage of this. In a bid to minimise the threat, most of the domains were purchased by security professionals to prevent threat actors from using them. In the wrong hands, threat actors could harvest credentials or host malicious content to be used in phishing campaigns.

Some examples seen being registered include fedetwitter[.]com to mimic fedex[.]com, roblotwitter[.]com to mimic roblix[.]com and netflitwitter[.]com to mimic Netflix.

As a precaution, threat intelligence teams are monitoring newly registered domains across the UK to identify any interaction with malicious content. Individuals and businesses are advised to take care when visiting sites originating from Twitter, as well as links received in direct messages.
