- In a first, cryptographic keys protecting SSH connections stolen in new attack
OpenSSH is safe, however, other implementations (from Zyxel and Cisco) are not: "The countermeasure to the attacks we describe in this paper is well known: implementations should validate signatures before sending them. OpenSSH, the most common SSH implementation we observed in this data, implements this countermeasure because it uses OpenSSL to generate signatures, and OpenSSL has included countermeasures against RSA fault attacks since 2001."
- 21 Vulnerabilities Discovered in Crucial IT-OT Connective Routers
I can't wait to get the details on this one: "We will demonstrate how one of these vulnerabilities allows for full control of the device. We will also discuss how these open-source components were missed by some commercial SBoM tools that rely on firmware analysis. We found more than 80,000 of these devices exposed via the Internet and potentially affected by past and present vulnerabilities. To better understand the threat landscape, we deployed high-interaction honeypots and a real physical device on the public Internet. We will cover the analysis of the attempted port scans and exploitation trials."

- Did iOS 17.1.1 fix Flipper Zero attack problem on iPhones? Not according to my tests
"However, there's also bad news, and that is that despite the popups seemingly being throttled, now all the Bluetooth attacks the Flipper Zero can generate can lock up the attacked iPhone solid, requiring a reboot. Previously only an attack specifically designed to lock up an iPhone could achieve this."
- Denial of Pleasure: Attacking Unusual BLE Targets with a Flipper Zero
"By playing around with the Love Spouse application, we can easily see that there is a startup packet for each expected vibration command and a single stop packet. There is no differentiation even between models. With this information, we are ready to develop an app for Flipper Zero that replicates the behavior of the app regarding startup and can create a Denial of Pleasure by continuously broadcasting the stop packet." - This is a supply chain issue as toys use the same chipset and respond to the same commands?

- 50 Shades of Vulnerabilities: Uncovering Flaws in Open-Source Vulnerability Disclosures
This is amazing work: "By utilizing the NVD API to fetch recently pushed CVEs and searching for GitHub references, we can then check if the commit/PR referenced by NVD has a release on GitHub that includes them. If not, this often presents a 'Half-Day' scenario, where a vulnerability is exposed without a patch at that stage." - There is a lot to unpack, but I go back to my previous comments on the difficulty of hiding vulnerabilities in open-source code once a vulnerability has been discovered.

This is the code referenced above that you can run and collect "Half-Day" vulnerabilities.

Let's write something ourselves to allow us to see all the cameras: "The company maintains a custom-built platform/website that certain employees use to manage the camera system. It lets them manage the cameras, download noteworthy “incident” videos, and view the live feeds. It is a React-based platform that interacts with a server using APIs. The website is publicly accessible, but all functionality is locked behind a corporate login page."

"using a commercial handheld Geiger counter (GMC-320+) and its audio output as a generic input for any MCU. The (pulsed) audio signal is amplified with an opamp (left unspecified) that connects to a GPIO pin of the MCU (RP2040-based Pico W). Here the same algorithm is used to create a continuous queue of randomly picked numbers, which can also be queried via the WiFi interface with a custom protocol, essentially making it a network-connected RNG that could be used by other network-connected appliances."

- Cyber ops linked to Israel-Hamas conflict largely improvised, researchers say
In the wake of Hamas’s attack on Israel, researchers and cybersecurity firms observed an uptick in operations by hacktivists and state-sponsored hacking groups. But more than one month into the conflict, researchers are increasingly concluding that cyberoperations linked to the war have been mostly opportunistic in nature and frequently exaggerated in terms of their impact.

In May of this year, more than 20 critical infrastructure organizations in Denmark were targeted with cyberattacks. A report published by SektorCERT, the Danish cybersecurity organization for critical infrastructure sectors details the attacks, which were carried out through two known vulnerabilities in Zyxel firewalls. Report: https://dd80b675424c132b90b3-e48385e382d2e5d17821a5e1d8e4c86b.ssl.cf1.rackcdn.com/external/sektorcert-the-attack-against-danish-critical-infrastructure-tlp-clear.pdf

- City of Huber Heights – Ransomware Attack UPDATE
The government of the City of Huber Heights, Ohio, is recovering from a ransomware attack. The city notified residents of the situation on the morning of Sunday, November 12, noting that “while public safety services are not impacted the following city divisions are affected: Zoning, Engineering, Tax, Finance, Utilities, Human Resources, and Economic Development.”
Of note: Providing updates every day at 2PM, City Manager steps up as POC.
- ICBC hit by ransomware impacting global trades
China's largest bank, ICBC, was hit by ransomware that resulted in disruption of financial services (FS) systems on Thursday Beijing time. ICBC is the largest commercial bank in the world based on revenue. As they cannot connect to DTCC/NSCC they are unable to clear transactions, which is having impacts on US Treasury trades, which is why they are sending messengers to manually do so.
The attackers appear to have leveraged Citrix Bleed to own the bank's unpatched Citrix server. To abuse an old story - but for a patch, the battle was lost.

- Reptar: A CPU Flaw in Microcode.
Many x86 processors have a flaw in the microcode which can be triggered by assembly language instructions with multiple prefixes. This can cause branches to unexpected locations, unconditional branches being ignored and the processor no longer accurately recording the instruction pointer. This may lead to privilege escalation, but that exploit has not been developed yet. There is a PoC tool used to demonstrate the flaw.
Some of the processors that have this feature include:
Ice Lake Rocket Lake Tiger Lake Raptor Lake Alder Lake Sapphire Rapids
- ChatGPT’s New Code Interpreter Has Giant Security Hole, Allows Hackers to Steal Your Data
The new feature lets you upload files, but it also makes them vulnerable to exposure. An attacker would need to trick the ChatGPT user into entering a prompt containing a malicious third-party URL which can exfiltrate data from the files. This amounts to a high-level version of cross-site scripting.
