Criminal Gang Physically Assaulting People for Their Cryptocurrency

This is pretty horrific:

…a group of men behind a violent crime spree designed to compel victims to hand over access to their cryptocurrency savings. That announcement and the criminal complaint laying out charges against St. Felix focused largely on a single theft of cryptocurrency from an elderly North Carolina couple, whose home St. Felix and one of his accomplices broke into before physically assaulting the two victims—­both in their seventies—­and forcing them to transfer more than $150,000 in Bitcoin and Ether to the thieves’ crypto wallets.

I think cryptocurrencies are more susceptible to this kind of real-world attack because they are largely outside the conventional banking system. Yet another reason to stay away from them.

Cloudflare Reports that Almost 7% of All Internet Traffic Is Malicious

6.8%, to be precise.

From ZDNet:

However, Distributed Denial of Service (DDoS) attacks continue to be cybercriminals’ weapon of choice, making up over 37% of all mitigated traffic. The scale of these attacks is staggering. In the first quarter of 2024 alone, Cloudflare blocked 4.5 million unique DDoS attacks. That total is nearly a third of all the DDoS attacks they mitigated the previous year.

But it’s not just about the sheer volume of DDoS attacks. The sophistication of these attacks is increasing, too. Last August, Cloudflare mitigated a massive HTTP/2 Rapid Reset DDoS attack that peaked at 201 million requests per second (RPS). That number is three times bigger than any previously observed attack.

It wasn’t just Cloudflare that was hit by the largest DDoS attack in its history. Google Cloud reported the same attack peaked at an astonishing 398 million RPS. So, how big is that number? According to Google, Google Cloud was slammed by more RPS in two minutes than Wikipedia saw traffic during September 2023.

Hacking Scientific Citations

Some scholars are inflating their reference counts by sneaking them into metadata:

Citations of scientific work abide by a standardized referencing system: Each reference explicitly mentions at least the title, authors’ names, publication year, journal or conference name, and page numbers of the cited publication. These details are stored as metadata, not visible in the article’s text directly, but assigned to a digital object identifier, or DOI—a unique identifier for each scientific publication.

References in a scientific publication allow authors to justify methodological choices or present the results of past studies, highlighting the iterative and collaborative nature of science.

However, we found through a chance encounter that some unscrupulous actors have added extra references, invisible in the text but present in the articles’ metadata, when they submitted the articles to scientific databases. The result? Citation counts for certain researchers or journals have skyrocketed, even though these references were not cited by the authors in their articles.

[…]

In the journals published by Technoscience Academy, at least 9% of recorded references were “sneaked references.” These additional references were only in the metadata, distorting citation counts and giving certain authors an unfair advantage. Some legitimate references were also lost, meaning they were not present in the metadata.

In addition, when analyzing the sneaked references, we found that they highly benefited some researchers. For example, a single researcher who was associated with Technoscience Academy benefited from more than 3,000 additional illegitimate citations. Some journals from the same publisher benefited from a couple hundred additional sneaked citations.

Be careful what you’re measuring, because that’s what you’ll get. Make sure it’s what you actually want.

Friday Squid Blogging: 1994 Lair of Squid Game

I didn’t know:

In 1994, Hewlett-Packard released a miracle machine: the HP 200LX pocket-size PC. In the depths of the device, among the MS-DOS productivity apps built into its fixed memory, there lurked a first-person maze game called Lair of Squid.

[…]

In Lair of Squid, you’re trapped in an underwater labyrinth, seeking a way out while avoiding squid roaming the corridors. A collision with any cephalopod results in death. To progress through each stage and ascend to the surface, you locate the exit and provide a hidden, scrambled code word. The password is initially displayed as asterisks, with letters revealed as you encounter them within the maze.

The NSA Has a Long-Lost Lecture by Adm. Grace Hopper

The NSA has a video recording of a 1982 lecture by Adm. Grace Hopper titled “Future Possibilities: Data, Hardware, Software, and People.” The agency is (so far) refusing to release it.

Basically, the recording is in an obscure video format. People at the NSA can’t easily watch it, so they can’t redact it. So they won’t do anything.

With digital obsolescence threatening many early technological formats, the dilemma surrounding Admiral Hopper’s lecture underscores the critical need for and challenge of digital preservation. This challenge transcends the confines of NSA’s operational scope. It is our shared obligation to safeguard such pivotal elements of our nation’s history, ensuring they remain within reach of future generations. While the stewardship of these recordings may extend beyond the NSA’s typical purview, they are undeniably a part of America’s national heritage.

Surely we can put pressure on them somehow.

RADIUS Vulnerability

New attack against the RADIUS authentication protocol:

The Blast-RADIUS attack allows a man-in-the-middle attacker between the RADIUS client and server to forge a valid protocol accept message in response to a failed authentication request. This forgery could give the attacker access to network devices and services without the attacker guessing or brute forcing passwords or shared secrets. The attacker does not learn user credentials.

This is one of those vulnerabilities that comes with a cool name, its own website, and a logo.

News article. Research paper.

Reverse-Engineering Ticketmaster’s Barcode System

Interesting:

By reverse-engineering how Ticketmaster and AXS actually make their electronic tickets, scalpers have essentially figured out how to regenerate specific, genuine tickets that they have legally purchased from scratch onto infrastructure that they control. In doing so, they are removing the anti-scalping restrictions put on the tickets by Ticketmaster and AXS.

EDITED TO ADD (7/14): More information.
