DNSCrypt-proxy is an open-source and free software designed to encrypt DNS traffic, thus protecting it from eavesdropping and manipulation. This is also useful to evade DNS censorship when DNSCrypt-proxy is configured correctly with Wireguard or OpenVPN. Further, DNSCrypt-proxy can configured to block malware, trackers, and internet ads. In Debian 11 and 12, using DNSCrypt-proxy can enhance privacy and security by preventing DNS spoofing attacks, DNS hijacking, and surveillance of DNS traffic. It ensures that DNS queries are encrypted, authenticated, and secure, thereby safeguarding users' browsing activities and sensitive information. Let us see how to install dnscrypt-proxy on Debian Linux 11 and 12.

If you are writing a Bash shell script, you should read command-line arguments into an array for some time. This allows us to process any number of arguments provided when the script is run. This makes the script adaptable to different use cases. Instead of dealing with fixed variables like $1, $2, $3, etc., you can work with any number of arguments more dynamically using bash for loop or bash while loop, depending upon your needs. Arrays make it simple to loop through each argument and perform operations on them, whether basic printing or complex processing. Bash provides a mapfile (readarray command) internal built-in command to read lines from a file into an array variable. Let us see how to use mapfile to read all command line arguments into an array.

CentOS, RHEL (Red Hat Enterprise Linux), Fedora and other clones of RHEL, such as Oracle, Alma, and Rocky, offer support for version pinning. This feature allows developers and system administrators to lock a particular package to a specific version, preventing it from being automatically updated by yum or dnf commands. Sometimes, it is necessary to protect packages from being updated to newer versions to avoid incompatibility issues with your applications. For example, you can lock down PHP version 8.3.6 and avoid using updated PHP version 8.4. Let us see how to lock a package to a specific version, only exclude a package from yum update or dnf update on a CentOS, RHEL, Fedora, and friends.

Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

Amazon Targets Vibe Coders With a New Cursor Killer IDE, Also Available on Linux  It's FOSS News

Linux Phone  Hackaday

Ukrainian hacker group BO Team, with help from the Ukrainian Cyber Alliance and possibly Ukraine's military, claims to have wiped out one of Russia's largest military drone manufacturers, destroying 47TB of production data and even disabling the doors in the facility. "Or, as described by the hacking collective (per Google translate), they 'deeply penetrated' the drone manufacturer 'to the very tonsils of demilitarization and denazification,'" reports The Register. From the report: BO Team (also known as Black Owl) announced the breach on its Telegram channel, and claimed to have carried out the operation alongside fellow hackers the Ukrainian Cyber Alliance "and one very well-known organization, the mention of which makes Vanya's bottle receivers explode," according to a Google translation of the Russian text. While the "very well-known organization" isn't named, BO Team included a link to Ukraine's Ministry of Defence. The military intelligence agency, working alongside the attackers, "carried out large-scale work to capture the entire network and server infrastructure of Gaskar Group, collect valuable information about the UAVs being produced and prospective, and then destroy the information and disable this infrastructure," the Telegram post continued. This reportedly included 47TB of technical information about the production of Russian drones, and BO Team claims to have destroyed all of the information on Gaskar's servers, including 10TB of backup files. "By the way, from the information we received, China is providing assistance in the production and training of specialists of Gaskar Group," the hackers added via Telegram. BO Team also posted what they claim to be confidential employee questionnaires [PDF]. On their own Telegram channel, the Ukrainian Cyber Alliance said they also stole "all the source code" before destroying everything. "The network went down so thoroughly that the doors in the building were blocked," the pro-Ukraine crew wrote, per Google translate. "To open them, the administration had to turn on the fire alarm. Most likely, the defense order is on the verge of failure, and thousands of drones will not get to the front in the near future."

Dictionary.com abruptly deleted all user accounts and saved word lists from its premium apps without notice or refunds, leaving long-time logophiles "devastated." "The company deleted all accounts, as well as the only ways to use Dictionary.com without seeing ads -- even if you previously paid for an ad-free experience," reports Ars Technica. From the report: Dictionary.com offers a free dictionary through its website and free Android and iOS apps. It used to offer paid-for mobile apps, called Dictionary.com Pro, that let users set up accounts, use the app without ads, and enabled other features (like grammar tips and science and rhyming dictionaries) that are gone now. Dictionary.com's premium apps also let people download an offline dictionary (its free apps used to let you buy a downloadable dictionary as a one-time purchase), but offline the dictionaries aren't available anymore. About a year ago, claims of Dictionary.com's apps being buggy surfaced online. We also found at least one person claiming that they were unable to buy an ad-free upgrade at that time. Reports of Dictionary.com accounts being deleted and the apps not working as expected, and with much of its content removed, started appearing online about two months ago. Users reported being unable to log in and access premium features, like saved words. Soon after, Dictionary.com's premium apps were removed from Google Play and Apple's App Store. The premium version was available for download for $6 as recently as March 23, per the Internet Archive's Wayback Machine.
