It turns out that all cluster mailboxes in the Denver area have the same master key. So if someone robs a postal carrier, they can open any mailbox.
I get that a single master key makes the whole system easier, but it’s very fragile security.

Hacking Digital License Plates
Not everything needs to be digital and “smart.” License plates, for example:
Josep Rodriguez, a researcher at security firm IOActive, has revealed a technique to “jailbreak” digital license plates sold by Reviver, the leading vendor of those plates in the US with 65,000 plates already sold. By removing a sticker on the back of the plate and attaching a cable to its internal connectors, he’s able to rewrite a Reviver plate’s firmware in a matter of minutes. Then, with that custom firmware installed, the jailbroken license plate can receive commands via Bluetooth from a smartphone app to instantly change its display to show any characters or image...

Short-Lived Certificates Coming to Let’s Encrypt
Starting next year:
Our longstanding offering won’t fundamentally change next year, but we are going to introduce a new offering that’s a big shift from anything we’ve done before—short-lived certificates. Specifically, certificates with a lifetime of six days. This is a big upgrade for the security of the TLS ecosystem because it minimizes exposure time during a key compromise event.
Because we’ve done so much to encourage automation over the past decade, most of our subscribers aren’t going to have to do much in order to switch to shorter lived certificates. We, on the other hand, are going to have to think about the possibility that we will need to issue 20x as many certificates as we do now. It’s not inconceivable that at some point in our next decade we may need to be prepared to issue 100,000,000 certificates per day...

Ultralytics Supply-Chain Attack
Last week, we saw a supply-chain attack against the Ultralytics AI library on GitHub. A quick summary:
On December 4, a malicious version 8.3.41 of the popular AI library ultralytics —which has almost 60 million downloads—was published to the Python Package Index (PyPI) package repository. The package contained downloader code that was downloading the XMRig coinminer.

For a technology that seems startling in its modernity, AI sure has a long history. Google Translate, OpenAI chatbots, and Meta AI image generators are built on decades of advancements in linguistics, signal processing, statistics, and other fields going back to the early days of computing—and, often, on seed funding from the U.S. Department of Defense. But today’s tools are hardly the intentional product of the diverse generations of innovators that came before. We agree with Morozov that the “refuseniks,” as he calls them, are wrong to see AI as “irreparably tainted” by its origins. AI is better understood as a creative, global field of human endeavor that has been largely captured by U.S. venture capitalists, private equity, and Big Tech. But that was never the inevitable outcome, and it doesn’t need to stay that way...

Fifteen years ago I blogged about a different SQUID. Here’s an update:
Fleeing drivers are a common problem for law enforcement. They just won’t stop unless persuaded—persuaded by bullets, barriers, spikes, or snares. Each option is risky business. Shooting up a fugitive’s car is one possibility. But what if children or hostages are in it? Lay down barriers, and the driver might swerve into a school bus. Spike his tires, and he might fishtail into a van—if the spikes stop him at all. Existing traps, made from elastic, may halt a Hyundai, but they’re no match for a Hummer. In addition, officers put themselves at risk of being run down while setting up the traps...

Algorithms Are Coming for Democracy—but It’s Not All Bad
In 2025, AI is poised to change every aspect of democratic politics—but it won’t necessarily be for the worse.

Most of 2023’s Top Exploited Vulnerabilities Were Zero-Days
Zero-day vulnerabilities are more commonly used, according to the Five Eyes:
Key Findings
In 2023, malicious cyber actors exploited more zero-day vulnerabilities to compromise enterprise networks compared to 2022, allowing them to conduct cyber operations against higher-priority targets. In 2023, the majority of the most frequently exploited vulnerabilities were initially exploited as a zero-day, which is an increase from 2022, when less than half of the top exploited vulnerabilities were exploited as a zero-day.
Malicious cyber actors continue to have the most success exploiting vulnerabilities within two years after public disclosure of the vulnerability. The utility of these vulnerabilities declines over time as more systems are patched or replaced. Malicious cyber actors find less utility from zero-day exploits when international cybersecurity efforts reduce the lifespan of zero-day vulnerabilities...

Prompt Injection Defenses Against LLM Cyberattacks
Interesting research: “Hacking Back the AI-Hacker: Prompt Injection as a Defense Against LLM-driven Cyberattacks“:
Large language models (LLMs) are increasingly being harnessed to automate cyberattacks, making sophisticated exploits more accessible and scalable. In response, we propose a new defense strategy tailored to counter LLM-driven cyberattacks. We introduce Mantis, a defensive framework that exploits LLMs’ susceptibility to adversarial inputs to undermine malicious operations. Upon detecting an automated cyberattack, Mantis plants carefully crafted inputs into system responses, leading the attacker’s LLM to disrupt their own operations (passive defense) or even compromise the attacker’s machine (active defense). By deploying purposefully vulnerable decoy services to attract the attacker and using dynamic prompt injections for the attacker’s LLM, Mantis can autonomously hack back the attacker. In our experiments, Mantis consistently achieved over 95% effectiveness against automated LLM-driven attacks. To foster further research and collaboration, Mantis is available as an open-source tool: ...

Really interesting research: “An LLM-Assisted Easy-to-Trigger Backdoor Attack on Code Completion Models: Injecting Disguised Vulnerabilities against Strong Detection“:
Abstract: Large Language Models (LLMs) have transformed code com-
pletion tasks, providing context-based suggestions to boost developer productivity in software engineering. As users often fine-tune these models for specific applications, poisoning and backdoor attacks can covertly alter the model outputs. To address this critical security challenge, we introduce CODEBREAKER, a pioneering LLM-assisted backdoor attack framework on code completion models. Unlike recent attacks that embed malicious payloads in detectable or irrelevant sections of the code (e.g., comments), CODEBREAKER leverages LLMs (e.g., GPT-4) for sophisticated payload transformation (without affecting functionalities), ensuring that both the poisoned data for fine-tuning and generated code can evade strong vulnerability detection. CODEBREAKER stands out with its comprehensive coverage of vulnerabilities, making it the first to provide such an extensive set for evaluation. Our extensive experimental evaluations and user studies underline the strong attack performance of CODEBREAKER across various settings, validating its superiority over existing approaches. By integrating malicious payloads directly into the source code with minimal transformation, CODEBREAKER challenges current security measures, underscoring the critical need for more robust defenses for code completion...

Google’s version looks pretty good: it’s detectable in text as small as 200 tokens.

China Possibly Hacking US “Lawful Access” Backdoor
The Wall Street Journal is reporting that Chinese hackers (Salt Typhoon) penetrated the networks of US broadband providers, and might have accessed the backdoors that the federal government uses to execute court-authorized wiretap requests. Those backdoors have been mandated by law—CALEA—since 1994.
It’s a weird story. The first line of the article is: “A cyberattack tied to the Chinese government penetrated the networks of a swath of U.S. broadband providers.” This implies that the attack wasn’t against the broadband providers directly, but against one of the intermediary companies that sit between the government CALEA requests and the broadband providers...

Hacking ChatGPT by Planting False Memories into Its Data
This vulnerability hacks a feature that allows ChatGPT to have long-term memory, where it uses information from past conversations to inform future conversations with that same user. A researcher found that he could use that feature to plant “false memories” into that context window that could subvert the model.

A malware campaign uses the unusual method of locking users in their browser’s kiosk mode to annoy them into entering their Google credentials, which are then stolen by information-stealing malware.
Specifically, the malware “locks” the user’s browser on Google’s login page with no obvious way to close the window, as the malware also blocks the “ESC” and “F11” keyboard keys. The goal is to frustrate the user enough that they enter and save their Google credentials in the browser to “unlock” the computer.

Israel’s Pager Attacks and Supply Chain Vulnerabilities

And we have no good means to defend ourselves.
Though the deadly operations were stunning, none of the elements used to carry them out were particularly new.

By deliberately moving bikes to create artificial problems, and exploiting exactly how the system calculates rewards, some people are making a lot of money.
At 10 a.m. on a Tuesday last month, seven Bike Angels descended on the docking station at Broadway and 53rd Street, across from the Ed Sullivan Theater.

These particular attacks from North Korean state-funded hacking team Lazarus Group are new, but the overall malware campaign against the Python development community has been running since at least August of 2023, when a number of popular open source Python tools were maliciously duplicated with added malware. Now, though, there are also attacks involving “coding tests” that only exist to get the end user to install hidden malware on their system (cleverly hidden with Base64 encoding) that allows remote execution once present.

The first new algorithm Microsoft added to SymCrypt is called ML-KEM. Previously known as CRYSTALS-Kyber, ML-KEM is one of three post-quantum standards formalized last month by the National Institute of Standards and Technology (NIST). The KEM in the new name is short for key encapsulation. KEMs can be used by two parties to negotiate a shared secret over a public channel. Shared secrets generated by a KEM can then be used with symmetric-key cryptographic operations, which aren’t vulnerable to Shor’s algorithm when the keys are of a sufficient size...

Evaluating the Effectiveness of Reward Modeling of Generative AI Systems
New research evaluating the effectiveness of reward modeling during Reinforcement Learning from Human Feedback (RLHF): “SEAL: Systematic Error Analysis for Value ALignment.” The paper introduces quantitative metrics for evaluating the effectiveness of modeling and aligning human values:
Abstract: Reinforcement Learning from Human Feedback (RLHF) aims to align language models (LMs) with human values by training reward models (RMs) on binary preferences and using these RMs to fine-tune the base LMs. Despite its importance, the internal mechanisms of RLHF remain poorly understood. This paper introduces new metrics to evaluate the effectiveness of modeling and aligning human values, namely feature imprint, alignment resistance and alignment robustness. We categorize alignment datasets into target features (desired values) and spoiler features (undesired concepts). By regressing RM scores against these features, we quantify the extent to which RMs reward them a metric we term feature imprint. We define alignment resistance as the proportion of the preference dataset where RMs fail to match human preferences, and we assess alignment robustness by analyzing RM responses to perturbed inputs. Our experiments, utilizing open-source components like the Anthropic preference dataset and OpenAssistant RMs, reveal significant imprints of target features and a notable sensitivity to spoiler features. We observed a 26% incidence of alignment resistance in portions of the dataset where LM-labelers disagreed with human preferences. Furthermore, we find that misalignment often arises from ambiguous entries within the alignment dataset. These findings underscore the importance of scrutinizing both RMs and alignment datasets for a deeper understanding of value alignment...
