With a simple exploit , browsers like Chrome and Safari can be tricked into handing over your credit carte du jour entropy to hackers . And you would n’t even realize it .
Viljami Kuosmanenis a cyberpunk withFuturiceandtook to Githuband Twitter to point out a simple feat on malicious websites that can rip you off . As he excuse , internet browser like Chrome and Safari are congeal to autofill information into text boxes with data like your phone phone number , address , credit card act , etc . Typically , browsers will determine the type of selective information the site is demand for , then keep the rest . But , Kuosmanennotes , hackers can obscure certain schoolbook box — think user would n’t they ’ve been autofilled . And since the malicious websites can be designed to look like pretty much anything , the danger is real .
Here ’s what the exploit look like :

So even if you only input your information the textbook box you saw , Chrome could have autofilled hidden box with more sensible material . And because the site would have to be laid out specifically to hide boxes , you would n’t necessarily notice that the information was being sent . That ’s not undecomposed if the data let in credit card information .
In the replies to the original tweet , other user suggested simple fixture to the affect browsers , likenotifying userswhat information they ’ve filled in before submitting or simplyrestricting autofillto only seeable boxes . For now , the wanton way to avoid the exploit is simply to disable your autofill feature .
Disabling autofillon Chrome is accessed first by cluck Preferences and then Show Advanced configurations . you could also go tochrome://options/. From there , you just uncheck the box :
Disabling autofillon Safari is access first via Preferences and then by go to the ‘ AutoFill ’ check and unchecking the box seat .
Firefox requires manual autofill for text box , meaning you have to at least vacillate over a text corner before it ’s filled in . That means the effort wo n’t work as well in the internet browser , since you ca n’t replete in the boxes you ca n’t see .
We arrive at out to Apple and Google for comment on Kuosmanen ’s exploit and how to avoid it . We ’ll update this post if we hear back .
