That is exactly what this vulnerability would have allowed. This vulnerability allowed malicious websites to masquerade as trusted websites when viewed on Desktop Safari (like on Mac computers) or Mobile Safari (like on iPhones or iPads). Hackers could then use their fraudulent identity to invade users' privacy. This worked because Apple lets users permanently save their security settings on a [per-website basis](https://support.apple.com/guide/safari/customize-settings-per-website-ibrw7f78f7fe/mac). If the malicious website wanted camera access, all it had to do was masquerade as a trusted video-conferencing website such as Skype or Zoom. ![badads.png](https://static.wixstatic.com/media/149864_f3f2f367ac724735ac4281012f1d44ea~mv2.png/v1/fill/w_519,h_292,al_c,q_85,usm_0.66_1.00_0.01,enc_avif,quality_auto/badads.png) Is an ad banner watching you? I posted the technical details of how I found this bug in a lengthy walkthrough [here](https://www.ryanpickren.com/webcam-hacking). My research uncovered seven zero-day vulnerabilities in Safari (CVE-2020-3852, CVE-2020-3864, CVE-2020-3865, CVE-2020-3885, CVE-2020-3887, CVE-2020-9784, & CVE-2020-9787), three of which were used in the kill chain to access the camera. Put simply - the bug tricked Apple into thinking a malicious website was actually a trusted one. It did this by exploiting a series of flaws in how Safari was parsing [URIs](https://developer.mozilla.org/en-US/docs/Glossary/URI), managing web [origins](https://developer.mozilla.org/en-US/docs/Glossary/Origin), and initializing [secure contexts](https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts). If a malicious website strung these issues together, it could use JavaScript to directly access the victim's webcam without asking for permission. Any JavaScript code with the ability to create a popup (such as a standalone website, embedded ad banner, or browser extension) could launch this attack. I reported this bug to Apple in accordance with the [Security Bounty Program rules](https://developer.apple.com/security-bounty/) and used [BugPoC](http://bugpoc.com) to give them a live demo. Apple considered this exploit to fall into the "[Network Attack without User Interaction: Zero-Click Unauthorized Access to Sensitive Data](https://developer.apple.com/security-bounty/payouts/)" category and awarded me $75,000. The below screen recording shows what this attack would look like if clicked from Twitter. ![macos-poc.gif](https://static.wixstatic.com/media/149864_b6a9268cffe34047a4797c88068e7669~mv2_d_1736_1380_s_2.gif) ![ios-poc.gif](https://static.wixstatic.com/media/149864_f088f74e64334c199a9dd4738555ffbc~mv2.gif) * victim in screen recording has previously trusted skype.com
