However, it seems that these attacks are being launched on very specific targets, rather than common users. This also shows that the crash point is not the first place of the vulnerability exploitation.įrom the view of attack technologies used, we can see that Pegasus is quite an advanced threat for iOS users. This is significant because the PAC security mechanism was developed to help prevent zero-click hacking.

This shows that the virtual functions table of the object JBIG2Segment had already been replaced, and the pointer authentication code (PAC) security feature was bypassed. But in actuality, it was already subverted to the current function itself (frame 0). Therefore, the frame 1 should have called the virtual function seg->getType(). This analysis is solely based on samples from Citizen Lab no new samples were obtained.

This crash happened when invoking CoreGraphics’ functionality for decoding JBIG2-encoded data in a PDF file. Our analysis focuses on the second crash, which is detailed in Figure 1.

The first crash apparently happened when invoking ImageIO’s functionality for rendering Adobe Photoshop PSD data. Amnesty Tech, a global collective of digital rights advocates and security researchers, also observed zero-click iMessage exploit activity during this period and referred to it as Megalodon.Īccording to the report from Citizen Lab, when the ForcedEntry exploit was launched against the victim’s device, the device logs showed two types of crashes. Then, in February 2021, the NSO Group started deploying the zero-click exploit that managed to circumvent BlastDoor, which Citizen Lab calls ForcedEntry. It was likely not effective against the iOS 14 update in September. The latter zero-click spyware is particularly notable because it can bypass security protections such as BlastDoor, which was designed by Apple to protect users against zero-click intrusions such as these.Īccording to Citizen Lab’s report, Kismet was used from July to September 2020 and was launched against devices running at least iOS 13.5.1 and 13.7. Zero-click attacks are labeled as sophisticated threats because unlike typical malware, they do not require user interaction to infect a device.

The activists were reportedly hacked with the NSO Group’s Pegasus spyware using two zero-click iMessage exploits: Kismet, which was identified in 2020 and ForcedEntry, a new vulnerability that was identified in 2021. The company has previously acknowledged similarly serious flaws and, in what Strafach estimated to be perhaps a dozen occasions, has noted that it was aware of reports that such security holes had been exploited.Ī woman walks past an Apple store in Beijing, China July 28, 2016.Citizen Lab has released a report detailing sophisticated iPhone exploits being used against nine Bahraini activists. Security researcher Will Strafach said he had seen no technical analysis of the vulnerabilities that Apple has just patched. Its spyware is known to have been used in Europe, the Middle East, Africa and Latin America against journalists, dissidents and human rights activists. NSO Group has been blacklisted by the U.S. READ MORE: Apple threatened to pull Facebook and Instagram from its app store over human trafficking In all cases, it cited an anonymous researcher.Ĭommercial spyware companies such as Israel’s NSO Group are known for identifying and taking advantage of such flaws, exploiting them in malware that surreptitiously infects targets’ smartphones, siphons their contents and surveils the targets in real time. The flaw also affects some iPod models.Īpple did not say in the reports how, where or by whom the vulnerabilities were discovered.

Security experts have advised users to update affected devices - the iPhone6S and later models several models of the iPad, including the 5th generation and later, all iPad Pro models and the iPad Air 2 and Mac computers running MacOS Monterey.

That would allow intruders to impersonate the device’s owner and subsequently run any software in their name, said Rachel Tobac, CEO of SocialProof Security.

SAN FRANCISCO (AP) - Apple disclosed serious security vulnerabilities for iPhones, iPads and Macs that could potentially allow attackers to take complete control of these devices.Īpple released two security reports about the issue on Wednesday, although they didn’t receive wide attention outside of tech publications.Īpple’s explanation of the vulnerability means a hacker could get “full admin access” to the device.
