Slashdot: ExpressVPN Gets Faster and More Secure, Thanks To Rust

ExpressVPN Gets Faster and More Secure, Thanks To Rust
Published on February 27, 2025 at 03:10AM
ZDNet's Steven Vaughan-Nichols shares some of the latest improvements to ExpressVPN following its codebase transition from C to Rust. An anonymous reader quotes an excerpt from the report: ExpressVPN is one of ZDNET's favorite Virtual Private Networks (VPNs). The popular VPN's transformation of its Lightway codebase from C to Rust promises to make the service faster and more secure. For now, the updated Lightway 2.0 is only available via ExpressVPN's Aircove router with the February 4 AircoveOS v5 update. The Aircove, which we rate as the best VPN router, costs $189. With this device, you can protect your tech from unwanted snoopers without installing a VPN on each gadget. So, how much faster is the updated ExpressVPN? In my tests, I connected to the internet via my updated router over my 2 Gigabit per second (Gbps) AT&T Internet using a 2.5 Gbps Ethernet-connected Linux Mint desktop with a Wi-Fi 6 connection over my Samsung Galaxy 25 Plus smartphone. Without the VPN engaged, I saw 1.6 Gbps speeds, which is about par. With the VPN switched on and using Lightway 2.0, I saw speeds in the 290 to 330 Megabit per second (Mbps) range to Toronto and London, England. Farther afield, I saw speeds around 250 to 280Mbps to Hong Kong and Seoul. That's about 20% faster than I had seen with earlier Lightway versions. I was impressed. This version of the VPN should also be more secure. As Pete Membrey, ExpressVPN's chief research officer, said in a statement: "At ExpressVPN, we innovate to solve the challenges of tomorrow. Upgrading Lightway from its previous C code to Rust was a strategic and straightforward decision to enhance performance and security while ensuring longevity." The updated Lightway VPN protocol also uses ML-KEM, the newly finalized NIST standard for post-quantum encryption. This feature, wrote Membray in a blog post, "ensures your connection is secured by encryption designed not just for today's threats but for the quantum-powered challenges of the future." To ensure the integrity of the recoded Lightway protocol, ExpressVPN commissioned two independent security audits from cybersecurity firms Cure53 and Praetorian. Both audits yielded positive results, with only minor vulnerabilities identified and promptly addressed by ExpressVPN. In short, ExpressVPN is technically about as safe a VPN as they come.

US Army Soldier Pleads Guilty To AT&T and Verizon Hacks Published on February 20, 2025 at 01:31AM Cameron John Wagenius pleaded guilty to hacking AT&T and Verizon and stealing a massive trove of phone records from the companies, according to court records filed on Wednesday. From a report: Wagenius, who was a U.S. Army soldier, pleaded guilty to two counts of "unlawful transfer of confidential phone records information" on an online forum and via an online communications platform. According to a document filed by Wagenius' lawyer, he faces a maximum fine of $250,000 and prison time of up to 10 years for each of the two counts. Wagenius was arrested and indicted last year. In January, U.S. prosecutors confirmed that the charges brought against Wagenius were linked to the indictment of Connor Moucka and John Binns, two alleged hackers whom the U.S. government accused of several data breaches against cloud computing services company Snowflake, which were among the ...

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features. Read more of this story at Slashdot.

Slashdot: Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications

Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications Published on December 16, 2024 at 01:04AM Launched in 2013, itch.io lets users host and sell indie video games online — now offering more than 200,000 — as well as other digital content like music and comics. But then someone uploaded a page based on a major videogame title, according to Game Rant. And somehow this provoked a series of overreactions and missteps that eventually knocked all of itch.io offline for several hours... The page was about the first release from game developer 10:10 — their game Funko Fusion, which features characters in the style of Funko's long-running pop-culture bobbleheads. As a major brand, Funko monitors the web with a "brand protection" partner (named BrandShield). Interestingly, BrandShield's SaaS product "leverages AI-driven online brand protection," according to their site, to "detect...
