This current update fixes a kernel vulnerability that would have allowed an attacker to “execute arbitrary code with system privileges” on an iPhone or iPad. Apple also mentioned Pwn20wnd, the hacker that released the public jailbreak. “We would like to acknowledge @Pwn20wnd for their assistance,” the company wrote in a security update.

As you might remember from the early days of the iPhone, jailbreaking allows users to install third-party apps that aren’t available through the App Store. But doing so also puts phones at risk of spyware. So, while the iOS 12.4 bug might have given us a trip down memory lane, you’ll want to download iOS 12.4.1 as soon as possible.

The majority of the vulnerabilities discovered by google were so-called “interactionless” bugs, meaning they can be executed on a remote iOS device without requiring any sort of direct interaction with the phone. An attacker simply has to send malicious code via iMessage and wait for the victim to open it. Because these “interactionless” bugs are in high demand for hackers, the security flaws discovered would have sold on the black market or other seedy parts of the internet for as much as $5 million apiece, according to ZDNet.

While Apple largely addressed these significant security flaws with the release of iOS 12.4 on July 22nd, the researchers are holding back on revealing the details of one vulnerability that has not yet been fully patched. Users are advised to keep their phones up to date and download updates as soon as they become available in order to avoid any significant security risks.

Getting a product like this off the ground is no easy feat, especially given that Apple’s decision to partner with Goldman Sachs meant two very different corporate cultures (Silicon Valley vs Wall Street) had to work together. Bloomberg reports that the two companies split up many of the responsibilities but worked together on the new technology. Along the way, Apple allegedly asked the bank to make changes regarding the card’s mechanics. But it appears that the core features Apple first touted survived.

While Apple hasn’t confirmed the August release date, we do know that employees and retail workers have been testing the card for several weeks. An early-August launch means the card would be ready for back-to-school shopping, and iOS 12.4, released earlier this week, has built-in Apple Card support. All signs point to an Apple Card launch in the coming weeks.
