Friday Squid Blogging: Live Colossal Squid Filmed

Fri, 04/18/2025 - 5:02pm

A live colossal squid was filmed for the first time in the ocean. It’s only a juvenile: a foot long.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Age Verification Using Facial Scans

Thu, 04/17/2025 - 12:38pm

Discord is testing the feature:

“We’re currently running tests in select regions to age-gate access to certain spaces or user settings,” a spokesperson for Discord said in a statement. “The information shared to power the age verification method is only used for the one-time age verification process and is not stored by Discord or our vendor. For Face Scan, the solution our vendor uses operates on-device, which means there is no collection of any biometric information when you scan your face. For ID verification, the scan of your ID is deleted upon verification.”...

CVE Program Almost Unfunded

Wed, 04/16/2025 - 11:19am

Mitre’s CVE’s program—which provides common naming and other informational resources about cybersecurity vulnerabilities—was about to be cancelled, as the US Department of Homeland Security failed to renew the contact. It was funded for eleven more months at the last minute.

This is a big deal. The CVE program is one of those pieces of common infrastructure that everyone benefits from. Losing it will bring us back to a world where there’s no single way to talk about vulnerabilities. It’s kind of crazy to think that the US government might damage its own security in this way—but I suppose no crazier than any of the other ways the US is working against its own interests right now...

Slopsquatting

Tue, 04/15/2025 - 12:02pm

As AI coding assistants invent nonexistent software libraries to download and use, enterprising attackers create and upload libraries with those names—laced with malware, of course.

Upcoming Speaking Engagements

This is a current list of where and when I am scheduled to speak:

  • I’m giving an online talk on AI and trust for the Weizenbaum Institute on April 24, 2025 at 2:00 PM CEST (8:00 AM ET).

China Sort of Admits to Being Behind Volt Typhoon

Mon, 04/14/2025 - 7:08am

The Wall Street Journal has the story:

Chinese officials acknowledged in a secret December meeting that Beijing was behind a widespread series of alarming cyberattacks on U.S. infrastructure, according to people familiar with the matter, underscoring how hostilities between the two superpowers are continuing to escalate.

The Chinese delegation linked years of intrusions into computer networks at U.S. ports, water utilities, airports and other targets, to increasing U.S. policy support for Taiwan, the people, who declined to be named, said.

The admission wasn’t explicit:...

Friday Squid Blogging: Squid and Efficient Solar Tech

Fri, 04/11/2025 - 7:06am

Researchers are trying to use squid color-changing biochemistry for solar tech.

This appears to be new and related research to a 2019 squid post.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

AI Vulnerability Finding

Fri, 04/11/2025 - 7:04am

Microsoft is reporting that its AI systems are able to find new vulnerabilities in source code:

Microsoft discovered eleven vulnerabilities in GRUB2, including integer and buffer overflows in filesystem parsers, command flaws, and a side-channel in cryptographic comparison.

Additionally, 9 buffer overflows in parsing SquashFS, EXT4, CramFS, JFFS2, and symlinks were discovered in U-Boot and Barebox, which require physical access to exploit.

The newly discovered flaws impact devices relying on UEFI Secure Boot, and if the right conditions are met, attackers can bypass security protections to execute arbitrary code on the device...

Reimagining Democracy

Thu, 04/10/2025 - 8:35pm

Imagine that all of us—all of society—have landed on some alien planet and need to form a government: clean slate. We do not have any legacy systems from the United States or any other country. We do not have any special or unique interests to perturb our thinking. How would we govern ourselves? It is unlikely that we would use the systems we have today. Modern representative democracy was the best form of government that eighteenth-century technology could invent. The twenty-first century is very different: scientifically, technically, and philosophically. For example, eighteenth-century democracy was designed under the assumption that travel and communications were both hard...

How to Leak to a Journalist

Neiman Lab has some good advice on how to leak a story to a journalist.

Arguing Against CALEA

Tue, 04/08/2025 - 7:08am

At a Congressional hearing earlier this week, Matt Blaze made the point that CALEA, the 1994 law that forces telecoms to make phone calls wiretappable, is outdated in today’s threat environment and should be rethought:

In other words, while the legally-mandated CALEA capability requirements have changed little over the last three decades, the infrastructure that must implement and protect it has changed radically. This has greatly expanded the “attack surface” that must be defended to prevent unauthorized wiretaps, especially at scale. The job of the illegal eavesdropper has gotten significantly easier, with many more options and opportunities for them to exploit. Compromising our telecommunications infrastructure is now little different from performing any other kind of computer intrusion or data breach, a well-known and endemic cybersecurity problem. To put it bluntly, something like Salt Typhoon was inevitable, and will likely happen again unless significant changes are made...
