Friday Squid Blogging: A Case of Squid Fossil Misidentification

Fri, 08/01/2025 - 5:01pm

What scientists thought were squid fossils were actually arrow worms.

Spying on People Through Airportr Luggage Delivery Service

Fri, 08/01/2025 - 7:07am

Airportr is a service that allows passengers to have their luggage picked up, checked, and delivered to their destinations. As you might expect, it’s used by wealthy or important people. So if the company’s website is insecure, you’d be able to spy on lots of wealthy or important people. And maybe even steal their luggage.

Researchers at the firm CyberX9 found that simple bugs in Airportr’s website allowed them to access virtually all of those users’ personal information, including travel plans, or even gain administrator privileges that would have allowed a hacker to redirect or steal luggage in transit. Among even the small sample of user data that the researchers reviewed and shared with WIRED they found what appear to be the personal information and travel records of multiple government officials and diplomats from the UK, Switzerland, and the US...

Cheating on Quantum Computing Benchmarks

Thu, 07/31/2025 - 7:00am

Peter Gutmann and Stephan Neuhaus have a new paper—I think it’s new, even though it has a March 2025 date—that makes the argument that we shouldn’t trust any of the quantum factorization benchmarks, because everyone has been cooking the books:

Similarly, quantum factorisation is performed using sleight-of-hand numbers that have been selected to make them very easy to factorise using a physics experiment and, by extension, a VIC-20, an abacus, and a dog. A standard technique is to ensure that the factors differ by only a few bits that can then be found using a simple search-based approach that has nothing to do with factorisation…. Note that such a value would never be encountered in the real world since the RSA key generation process typically requires that |p-q| > 100 or more bits [9]. As one analysis puts it, “Instead of waiting for the hardware to improve by yet further orders of magnitude, researchers began inventing better and better tricks for factoring numbers by exploiting their hidden structure” [10]...

Measuring the Attack/Defense Balance

Wed, 07/30/2025 - 7:07am

“Who’s winning on the internet, the attackers or the defenders?”

I’m asked this all the time, and I can only ever give a qualitative hand-wavy answer. But Jason Healey and Tarang Jain’s latest Lawfare piece has amassed data.

The essay provides the first framework for metrics about how we are all doing collectively—and not just how an individual network is doing. Healey wrote to me in email:

The work rests on three key insights: (1) defenders need a framework (based in threat, vulnerability, and consequence) to categorize the flood of potentially relevant security metrics; (2) trends are what matter, not specifics; and (3) to start, we should avoid getting bogged down in collecting data and just use what’s already being reported by amazing teams at Verizon, Cyentia, Mandiant, IBM, FBI, and so many others...

Microsoft SharePoint Zero-Day

Mon, 07/28/2025 - 7:09am

Chinese hackers are exploiting a high-severity vulnerability in Microsoft SharePoint to steal data worldwide:

The vulnerability, tracked as CVE-2025-53770, carries a severity rating of 9.8 out of a possible 10. It gives unauthenticated remote access to SharePoint Servers exposed to the Internet. Starting Friday, researchers began warning of active exploitation of the vulnerability, which affects SharePoint Servers that infrastructure customers run in-house. Microsoft’s cloud-hosted SharePoint Online and Microsoft 365 are not affected.

Subliminal Learning in AIs

Fri, 07/25/2025 - 7:10am

Today’s freaky LLM behavior:

We study subliminal learning, a surprising phenomenon where language models learn traits from model-generated data that is semantically unrelated to those traits. For example, a “student” model learns to prefer owls when trained on sequences of numbers generated by a “teacher” model that prefers owls. This same phenomenon can transmit misalignment through data that appears completely benign. This effect only occurs when the teacher and student share the same base model.

Interesting security implications.

I am more convinced than ever that we need serious research into ...

How Solid Protocol Restores Digital Agency

Thu, 07/24/2025 - 7:04am

The current state of digital identity is a mess. Your personal information is scattered across hundreds of locations: social media companies, IoT companies, government agencies, websites you have accounts on, and data brokers you’ve never heard of. These entities collect, store, and trade your data, often without your knowledge or consent. It’s both redundant and inconsistent. You have hundreds, maybe thousands, of fragmented digital profiles that often contain contradictory or logically impossible information. Each serves its own purpose, yet there is no central override and control to serve you—as the identity owner...

Google Sues the Badbox Botnet Operators

Wed, 07/23/2025 - 7:04am

It will be interesting to watch what will come of this private lawsuit:

Google on Thursday announced filing a lawsuit against the operators of the Badbox 2.0 botnet, which has ensnared more than 10 million devices running Android open source software.

These devices lack Google’s security protections, and the perpetrators pre-installed the Badbox 2.0 malware on them, to create a backdoor and abuse them for large-scale fraud and other illicit schemes.

This reminds me of Meta’s lawauit against Pegasus over its hack-for-hire software (which I wrote about ...

“Encryption Backdoors and the Fourth Amendment”

Tue, 07/22/2025 - 7:05am

Law journal article that looks at the Dual_EC_PRNG backdoor from a US constitutional perspective:

Abstract: The National Security Agency (NSA) reportedly paid and pressured technology companies to trick their customers into using vulnerable encryption products. This Article examines whether any of three theories removed the Fourth Amendment’s requirement that this be reasonable. The first is that a challenge to the encryption backdoor might fail for want of a search or seizure. The Article rejects this both because the Amendment reaches some vulnerabilities apart from the searches and seizures they enable and because the creation of this vulnerability was itself a search or seizure. The second is that the role of the technology companies might have brought this backdoor within the private-search doctrine. The Article criticizes the doctrine­ particularly its origins in Burdeau v. McDowell­and argues that if it ever should apply, it should not here. The last is that the customers might have waived their Fourth Amendment rights under the third-party doctrine. The Article rejects this both because the customers were not on notice of the backdoor and because historical understandings of the Amendment would not have tolerated it. The Article concludes that none of these theories removed the Amendment’s reasonableness requirement...

Another Supply Chain Vulnerability

Mon, 07/21/2025 - 7:04am

ProPublica is reporting:

Microsoft is using engineers in China to help maintain the Defense Department’s computer systems—with minimal supervision by U.S. personnel—leaving some of the nation’s most sensitive data vulnerable to hacking from its leading cyber adversary, a ProPublica investigation has found.

The arrangement, which was critical to Microsoft winning the federal government’s cloud computing business a decade ago, relies on U.S. citizens with security clearances to oversee the work and serve as a barrier against espionage and sabotage...

Friday Squid Blogging: The Giant Squid Nebula

Fri, 07/18/2025 - 5:06pm

Beautiful photo.

Difficult to capture, this mysterious, squid-shaped interstellar cloud spans nearly three full moons in planet Earth’s sky. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula’s bipolar shape is distinguished here by the telltale blue emission from doubly ionized oxygen atoms. Though apparently surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, one investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, the cosmic squid would represent a spectacular outflow of material driven by a ...

New Mobile Phone Forensics Tool

Fri, 07/18/2025 - 7:07am

The Chinese have a new tool called Massistant.

  • Massistant is the presumed successor to Chinese forensics tool, “MFSocket”, reported in 2019 and attributed to publicly traded cybersecurity company, Meiya Pico.
  • The forensics tool works in tandem with a corresponding desktop software.
  • Massistant gains access to device GPS location data, SMS messages, images, audio, contacts and phone services.
  • Meiya Pico maintains partnerships with domestic and international law enforcement partners, both as a surveillance hardware and software provider, as well as through training programs for law enforcement personnel...

Security Vulnerabilities in ICEBlock

Thu, 07/17/2025 - 7:06am

The ICEBlock tool has vulnerabilities:

The developer of ICEBlock, an iOS app for anonymously reporting sightings of US Immigration and Customs Enforcement (ICE) officials, promises that it “ensures user privacy by storing no personal data.” But that claim has come under scrutiny. ICEBlock creator Joshua Aaron has been accused of making false promises regarding user anonymity and privacy, being “misguided” about the privacy offered by iOS, and of being an Apple fanboy. The issue isn’t what ICEBlock stores. It’s about what it could accidentally reveal through its tight integration with iOS...

Hacking Trains

Wed, 07/16/2025 - 12:57pm

Seems like an old system system that predates any care about security:

The flaw has to do with the protocol used in a train system known as the End-of-Train and Head-of-Train. A Flashing Rear End Device (FRED), also known as an End-of-Train (EOT) device, is attached to the back of a train and sends data via radio signals to a corresponding device in the locomotive called the Head-of-Train (HOT). Commands can also be sent to the FRED to apply the brakes at the rear of the train.

These devices were first installed in the 1980s as a replacement for caboose cars, and unfortunately, they lack encryption and authentication protocols. Instead, the current system uses data packets sent between the front and back of a train that include a simple BCH checksum to detect errors or interference. But now, the CISA is warning that someone using a software-defined radio could potentially send fake data packets and interfere with train operations...

Squid Dominated the Oceans in the Late Cretaceous

Fri, 07/11/2025 - 5:04pm

New research:

One reason the early years of squids has been such a mystery is because squids’ lack of hard shells made their fossils hard to come by. Undeterred, the team instead focused on finding ancient squid beaks—hard mouthparts with high fossilization potential that could help the team figure out how squids evolved.

With that in mind, the team developed an advanced fossil discovery technique that completely digitized rocks with all their embedded fossils in complete 3D form. Upon using that technique on Late Cretaceous rocks from Japan, the team identified 1,000 fossilized cephalopod beaks hidden inside the rocks, which included 263 squid specimens and 40 previously unknown squid species...
