smith (CVE-2023-32434)
This write-up presents an exploit for a vulnerability in the XNU kernel: Assigned CVE-2023-32434. Fixed in iOS 16.5.1 and macOS 13.4.1. Reachable from the WebContent sandbox and might have been actively exploited. *Note that this CVE fixed multiple integer overflows, so it is unclear whether or not the integer overflow used in my exploit was also used in-the-wild. Moreover, if it was, it might not have been exploited in the same way. The exploit has been successfully tested on: iOS 16.3, 16.3.1, 16.4 and 16.5 (iPhone 14 Pro Max) macOS 13.1 and 13.4 (MacBook Air M2 2022) All code snippets shown below are from xnu-8792.81.2.

Personal Information Exploit on OpenAI’s ChatGPT Raise Privacy Concerns
Personal Information Exploit on OpenAI’s ChatGPT Raise Privacy Concerns
Last month, I received an alarming email from someone I did not know: Rui Zhu, a Ph.D. candidate at Indiana University Bloomington. Mr. Zhu had my email address, he explained, because GPT-3.5 Turbo, one of the latest and most robust large language models (L.L.M.) from OpenAI, had delivered it to him.

Google Online Security Blog: Expanding our exploit reward program to Chrome and Cloud
Google Online Security Blog: Expanding our exploit reward program to Chrome and Cloud
In 2020, we launched a novel format for our vulnerability reward program (VRP) with the kCTF VRP and its continuation kernelCTF. For the first time, security researchers could get bounties for n-day exploits even if they didn’t find the vulnerability themselves. This format proved valuable in improving our understanding of the most widely exploited parts of the linux kernel. Its success motivated us to expand it to new areas and we're now excited to announce that we're extending it to two new targets: v8CTF and kvmCTF.

0-days exploited by commercial surveillance vendor in Egypt
0-days exploited by commercial surveillance vendor in Egypt
Last week Google’s Threat Analysis Group (TAG), in partnership with The Citizen Lab, discovered an in-the-wild 0-day exploit chain for iPhones. Developed by the commercial surveillance vendor, Intellexa, this exploit chain is used to install its Predator spyware surreptitiously onto a device. In response, yesterday, Apple patched the bugs in iOS 16.7 and iOS 17.0.1 as CVE-2023-41991, CVE-2023-41992, CVE-2023-41993. This quick patching from Apple helps to better protect users and we encourage all iOS users to install them as soon as possible.

MAR-10430311-1.v1 Multiple Nation-State Threat Actors Exploit CVE-2022-47966 and CVE-2022-42475
CISA received 4 files for analysis from an incident response engagement conducted at an Aeronautical Sector organization. 2 files (bitmap.exe, wkHPd.exe) are identified as variants of Metasploit (Meterpreter) and designed to connect and receive unencrypted payloads from their respective command and control (C2) servers. Note: Metasploit is an open source penetration testing software; Meterpreter is a Metasploit attack payload that runs an interactive shell. These executables are used as attack payloads to run interactive shells, allowing a malicious actor the ability to control and execute code on a system. 2 files (resource.aspx, ConfigLogin.aspx) are Active Server Pages (ASPX) web shells designed to execute remote JavaScript code on the victim server.

New Apple iOS 16 Exploit Enables Stealthy Cellular Access Under Fake Airplane Mode
New Apple iOS 16 Exploit Enables Stealthy Cellular Access Under Fake Airplane Mode
Cybersecurity researchers have documented a novel post-exploit persistence technique on iOS 16 that could be abused to fly under the radar and maintain access to an Apple device even when the victim believes it is offline. The method "tricks the victim into thinking their device's Airplane Mode works when in reality the attacker (following successful device exploit) has planted an artificial Airplane Mode which edits the UI to display Airplane Mode icon and cuts internet connection to all apps except the attacker application," Jamf Threat Labs researchers Hu Ke and Nir Avraham said in a report shared with The Hacker News.
