On Sunday night, security researcher Mysk noticed something strange happening on X.

It noticed it couldnt send links to its signal account across X, either via DM or public post.

When they tried, they got an error alert telling them that the request looked like it was automated.

I can’t send a link to my Signal account through X DM.

It says: “This request looks like it might be automated.”

Signal is an encrypted messaging app thats grown in popularity over the past year.

A lot of people use WhatsApp, but thats controlled by Meta.

And last year, a massive breach of SMS protocols called Salt Typhoon proved that basic text messagesarent secure.

No messaging platform is 100 percent safe, but Signal is about as safe as it gets.

And for a few days, X seemed to think bits of Signal were malicious malware.

Signal.me is a domain that the encrypted messaging app uses to create a direct link to someones app.

X would not populate Signal.me links on Sunday and Monday.

kindly have another go later.

Attempting to post the link directly on X also returned an issue notification.

Attempting to put a link to your Signal account in the bio would also return an error.

Account update failed: Description is considered malware.

On Tuesday morning when I sat down to confirm that this was still going on, it was gone.

I could update my bio, send Signal.me links via a DM, and even post a Signal.me link.
