US Police Now Armed With Israeli Spy Vans Simulating Mobile Phone Towers

Longtime Slashdot reader schwit1 quotes an X post by Josh Walkos, author of the Substack We the Free: If you thought Flock was bad check out Falconet. Falconet from Israeli company Cognyte serves as a cell tower simulator that intercepts cell phone data from all devices within range. Police mount these systems in Tahoes so the vehicles can collect information while driving through areas without any direct interaction with targets. This mobile approach generates ongoing records of phone locations and communications for everyone nearby rather than only suspects, which creates comprehensive movement profiles and bypasses traditional warrant requirements under the Fourth Amendment. Cognyte sells the technology directly to U.S. agencies, as shown by the Texas Department of Public Safety purchase of four Tahoes where over three point eight million dollars went to the interception equipment. Adoption spreads through routine vehicle procurement with little external review of how the collected data is stored or shared. Once active the systems permit warrantless collection of private cell phone data across entire communities during normal patrols, which enables potential misuse and leaves individuals with no effective way to discover or contest the surveillance.

Drinking 5 Cups of Coffee a Day Could Reduce Heart Risk

A new American Heart Association scientific statement concludes that up to about 400 milligrams a day, or roughly three to five cups of plain coffee, is safe for most adults and may be linked to lower risks of cardiovascular disease. The benefits appear to depend heavily on the source and preparation, with coffee and tea looking more favorable than energy drinks, and added sugar, cream, syrups, or sweeteners potentially canceling out the upside. ScienceAlert reports: "Caffeine consumed in coffee is a key part of daily life for millions of people," says Gregory Marcus, cardiologist at the University of California, San Francisco, and Chair of the AHA volunteer writing group behind the statement. "In our review of the most recent research, for most adults, intake of up to 400 milligrams of caffeine per day, the equivalent of up to five cups of caffeinated coffee per day without added sugars or fillers, is safe and does not increase cardiovascular risk." The statement focused on caffeine's relationship with cardiovascular risk factors, such as blood pressure and diabetes, as well as types of cardiovascular disease, including arrhythmias, coronary artery disease, stroke, and heart failure. The picture that emerges is complicated, but generally positive. [...] All up, the new AHA statement concludes that there's a growing body of evidence that caffeine isn't harmful when taken in moderation, and that coffee specifically may be beneficial. The statement was published in the journal Circulation.

Hackers Are Exploiting Recently Patched WordPress Bugs, Putting Millions of Websites at Risk

An anonymous reader quotes a report from TechCrunch: Hackers are breaking into websites that run vulnerable versions of the popular blogging software WordPress, according to several cybersecurity firms. One estimate puts the number of vulnerable WordPress websites at tens of millions as of Monday. Last week, WordPress patched two critical security flaws, urging people who run its software on their websites to update it "immediately." The vulnerabilities are so severe that WordPress enabled forced updates where possible. Since then, cybersecurity companies Patchstack, Hexastrike, and WatchTowr have all warned that hackers are exploiting the vulnerabilities in the wild, meaning they are taking over websites that are still running susceptible versions of WordPress. It's unclear how many WordPress-powered websites on the internet are at risk, but it's possible to make some educated guesses. The vulnerable versions of WordPress are 6.9.0 through 6.9.4, and 7.0.0 to 7.0.1. According to WordPress' official stats, there are more than 400 million websites that run those flawed versions, although these statistics likely don't reflect websites that have recently been patched. Cybersecurity consultant Daniel Card, who told TechCrunch that he looked at a sample of around 3,500 WordPress websites, estimates that less than 15% are vulnerable. Applying Card's projection across the total population of WordPress websites on the internet, the total figure would still be around 90 million. [...] One of the critical WordPress bugs was found and reported by Adam Kues of cybersecurity firm Searchlight Cyber, which dubbed it WP2Shell. Paired with the other bug, hackers can take full remote control of vulnerable websites.

Regressive JPEGs

One of the cool features of JPEG files is that there's the option to save low frequency components first. This means that a partially downloaded image will be displayed at low resolution instead of being cut off. ↫ maurycyz.com Oh I know where this is going… Doing this, I can get Chrome to render around 90 frames before giving up. Other browsers like Firefox have more patience, but a 90 scan image seems to work almost everywhere. ↫ maurycyz.com Yes, you can abuse the mentioned feature to create a really odd type of video. Or animation? Well, it allows you to create something resembling a really low-resolution GIF. Useless, yes, but very novel.

“Even Microsoft couldn’t make Windows 11 work well on 8GB of RAM”

The Verge reviewed the latest Surface Laptop, which only comes with 8GB of RAM at a higher price than the previous 16GB model, and they conclude that Windows isn't really usable on 8GB of RAM. Whether that's true or not I do not know - I would assume it depends a lot on your usage - but this quote from the review I found quite peculiar: I was on a Microsoft Teams call (using the app, not a browser) when the host streamed a brief video, which made the whole laptop hang for several seconds. At the time, I had about 10 Chrome tabs open across two desktops, alongside Slack and Signal - not an obscene level of multitasking. ↫ Antonio G. Di Benedetto at The Verge Excuse me, but that is actually an obscene level of multitasking because every single one of those "applications" is a complete Chrome browser. Just in the paragraph above, there's four individual complete Chrome browsers running, with little to no optimisation. Why would anyone be surprised this scenario strains a mere 8GB of RAM? This isn't merely a Windows problem; this is a programmers choosing suboptimal tooling × managers have no idea what they're doing problem. If Teams, Slack, and Signal had been proper, native applications instead of websites running in terrible frameworks, Windows 11 would have handled this scenario just fine.

OpenBSD tests WPA3 support

The NLnet Foundation's NGI0 Commons Fund supported an effort to add WPA3 support to OpenBSD, and the work's payed off. All drivers which support PMF can use WPA3, which are: iwm, iwx, and qwx. So far, I have tested this patch on iwx AX200 only. I will roll out this patch to more of my devices now. Help with testing is welcome. There are both userland and kernel changes involved. ↫ Stefan Sperling Only the second implementation of WPA3 will be supported, which requires some explanation: WPA3 has a complicated history. There are two versions of WPA3. The initially standardized version suffered from side-channel leaks found by Mathy Vanhoef and dubbed "Dragonblood". A revised and fixed version has been standardized and is mandatory in the 6 GHz band as of Wifi 6e (11ax) and mandatory on all bands as of Wifi 7 (11be). ↫ Stefan Sperling Obviously, WPA3 is a very welcome addition to OpenBSD.
