Phishing Attacks Use This Simple Trick to Defeat iPhone Message Security

A new social engineering tactic is being used by cybercriminals to trick iPhone users into disabling iMessage's built-in phishing protection, in a bid to expose them to malicious links and scams, according to BleepingComputer.

General Apps Messages Redux
The scam exploits a security feature in iMessage that automatically disables links from unknown senders. Apple told the outlet that when users reply to these messages or add the sender to their contacts, the links become clickable – a behavior that scammers are now actively exploiting, according to the report. The deceptive messages often masquerade as notifications from trusted organizations like USPS or toll road authorities.

Scammers are apparently looking to exploit the familiar "reply STOP" or "reply NO" that often appears at the end of messages from authentic businesses or services, as there's been a surge in SMS phishing (smishing) attacks that specifically ask recipients to reply "Y" to "activate" supposedly legitimate links.

By getting users to respond, attackers not only enable the previously disabled links but also identify active phone numbers that are more likely to engage with future scams.

Tech-savvy users are likely to easily identify these as phishing attempts, but the main concern is that older or less experienced users will be particularly vulnerable to the tactic. Needless to say, the best way to ensure that you never fall for the scam is to never reply to suspicious messages from unknown senders.

Another line of defense is to enable message filtering on your iPhone or iPad. Message filtering sorts messages from people who are not in your contacts into a separate list, where you can more easily view them in the Messages app. To filter messages from unknown senders, open Settings and go to Apps ➝ Messages, then toggle on the switch next to Filter Unknown Senders.

Bear in mind that the feature can filter legitimate messages – from couriers or your bank, for example – so don't automatically assume that a filtered message is dodgy. And, as mentioned above, you can't open links in a message from an unknown sender until you add them to your contacts or reply to the message, but that's by design.

Why doesn't Apple use Apple Intelligence to detect and remove these things?

Genuine question, I know Apple Intelligence sucks at this time but I'm sure it can be easily trained to detect these samples?

“iPhone users hate this one trick…” is the only way this article could be more clickbait. /s

Snark aside… I eliminated this spamming by removing all my personal data from data brokers. It took me an entire Saturday, but I managed to remove my email/phone/address from over 40 online sources and I haven’t gotten a single SMS spam since. Not even during the US election season.

The faster we leave SMS behind the better.
I have had the same phone number for 20+ years and it must be part of an active list scammers use because at this point I receive phishing SMS's at least 2-3 times a week and regularly use TrueCaller to filter out this garbage.

Would be very interested to hear specifics on how you (or anyone else) did this. Did you pay for some service that automates it, or manually go through and fill out forms? Thanks!
