  • Fresh ransomware samples indicate REvil is back [Ed: Microsoft Windows TCO]

    New ransomware samples analyzed by Secureworks' threat intelligence team are the latest indication that high-profile ransomware operation REvil is once again up and running after months of relative inactivity.

    Secureworks' Counter Threat Unit (CTU) investigated samples that were uploaded to the VirusTotal analysis service and found some showing that the developer of the code has access to REvil's source code, "reinforcing the likelihood that the threat group has reemerged," the researchers wrote in a blog post this week.

  • US-Led Seizure of RaidForums May Defy Lasting Effect on Security | TechNewsWorld

    The U.S. Department of Justice on Tuesday announced it seized the website and user database for RaidForums, a popular English-language cybercrime forum that sold access to more than 10 billion consumer records stolen in some of the world’s largest data breaches since 2015.

    The DOJ also charged the alleged administrator of RaidForums — 21-year-old Diogo Santos Coelho, of Portugal — with six criminal counts, including conspiracy, access device fraud, and aggravated identity theft.

  • Malware goes regional as attackers change tactics [Ed: Microsoft Windows TCO]

    One such trend is that most recent malware attacks came from within the same region as the victim, a marked difference from previous years, according to Netskope, which believes this is a strategic tactic used by attackers to avoid geofencing filters and other prevention measures.

    [...]

    Netskope said that EXE and DLL files account for nearly half of all malware downloads as malicious actors continue to see Microsoft Windows as a prime target for attacks.

  • iOS, Android stores host more than 1.5 million 'abandoned' apps [Ed: Orphaned does not mean malicious]
  • OpenSSF Adds Open Source Package Analysis Tool Prototype

    The Open Source Security Foundation (OpenSSF) has made available a prototype of a package analysis tool that has already identified more than 200 malicious packages uploaded to PyPI and npm software components.

    The Open Source Security Foundation (OpenSSF) announced 15 new members from leading software development, cybersecurity, financial services, communications, and academic sectors.

  • Google to create security team for open source projects [Ed: Google works for the NSA. No security professional (a real security person) would take this seriously. Google: we worry about Open Source security! Meanwhile a Google engineer slips backdoored encryption into Linux kernel...]
  • Groundhog Day For Malware - IT Jungle [Ed: "This content is sponsored by iTech Solutions." IT Jungle has rapidly become a puff piece dump of IBM, Intel etc.]

    “The IFS just like a UNIX or Windows file system is susceptible to viruses, the i/OS is NOT.”

    Okay, this comment is pretty much false information. First, the IFS is called the Integrated File System because it’s exactly that. It literally contains ALL TEN IBM i file systems! Here they all are for good measure:

  • IBM Tackles Talent Shortage and Cybersecurity Crisis with New and Expanded Partnerships [Ed: IBM is moaning about talent shortage while laying off some of its most experienced workers]
  • Security is a pain for American Dental Association: Ransomware infection feared [Ed: The huge cost of using Microsoft Windows]

    The Black Basta crime gang has claimed it infected the American Dental Association with ransomware.

  • Microsoft closes Windows LSA hole under active attack [Ed: While the media obsesses over "Linux" (systemd) bugs that could be exploited, by a local user, Microsoft has these blunders that the media typically shies away from (zero-days, unlike Linux, and far more severe too)]
  • Microsoft patches Windows LSA spoofing zero-day under active attack (CVE-2022-26925) [Ed: With Microsoft, security is not a possibility. Microsoft security advice (that would actually work): turn off the computer until we issue a patch for the zero-day remotely-exploitable hole.]

    May 2022 Patch Tuesday is here, and Microsoft has marked it by releasing fixes for 74 CVE-numbered vulnerabilities, including one zero-day under active attack (CVE-2022-26925) and two publicly known vulnerabilities (CVE-2022-29972 and CVE-2022-22713).

  • US offers $15m reward for information about Conti ransomware gang [Ed: Microsoft Windows is costing the US taxpayers, too]
  • US, Europe formally blame Russia for data wiper attacks against Ukraine, Viasat [Ed: Windows TCO; But the Linux Foundation will carry on badmouth Linux security while taking Microsoft cash, just like Zemlin the wife. The Zemlin family bags more money from Microsoft than the Linux Foundation bags from Microsoft.]

    WhisperGate corrupts an infected Windows system's master boot record, displays a fake ransom note, and irreversibly scrambles documents based on their file extensions, according to the US government's Cybersecurity and Infrastructure Security Agency (CISA). Ghostwriter, a crew thought to be connected to Russia's GRU military intelligence service, started using this strain of malware against organizations in Ukraine on January 15, we're told.

  • How to Add Repository to Debian

    APT checks the health of all the packages, and dependencies of the package before installing it. APT fetches packages from one or more repositories. A repository (package source) is basically a network server. The term "package" refers to an individual file with a .deb extension that contains either all or part of an application. The normal installation comes with default repositories configured, but these contain only a few packages out of an ocean of free software available. In this tutorial, we learn how to add the package repository to Debian.

  • Making a Video of a Single Window

    I recently wanted to send someone a video of a program doing some interesting things in a single X11 window. Recording the whole desktop is easy (some readers may remember my post on Aeschylus which does just that) but it will include irrelevant (and possibly unwanted) parts of the screen, leading to unnecessarily large files. I couldn't immediately find a tool which did what I wanted on OpenBSD [1] but through a combination of xwininfo, FFmpeg, and hk I was able to put together exactly what I needed in short order. Even better, I was able to easily post-process the video to shrink its file size, speed it up, and contort it to the dimension requirements of various platforms. Here's a video straight out of the little script I put together: [...]

    And it got me thinking about what you can and can’t do — what you do and don’t have control over.

  • allow-new-zones in BIND 9.16 on CentOS 8 Stream under SELinux

    We run these training systems with SELinux enabled (I wouldn’t, but my colleague likes it :-), and that’s the reason I aborted the lab: I couldn’t tell students how to solve the cause other than by disabling SELinux entirely, but there wasn’t enough time for that.

  • Will the IndieWeb Ever Become Mainstream?

    This is an interesting question, thanks for asking it, Jeremy. I do have some history with the IndieWeb, and some opinions, so let’s dive in.

    The short answer to the question is a resounding no, and it all boils down to the fact that the IndieWeb is really complicated to implement, so it will only ever appeal to developers.

  • How to Install CUPS Print Server on Ubuntu 22.04

    If your business has multiple personal computers in the network which need to print, then we need a device called a print server. Print server act intermediate between PC and printers which accept print jobs from PC and send them to respective printers. CUPS is the primary mechanism in the Unix-like operating system for printing and print services. It can allow a computer to act as a Print server. In this tutorial, we learn how to set up CUPS print server on Ubuntu 22.04.

Open Hardware: XON/XOFF and Raspberry Pi Pico

  • From XON/XOFF to Forward Incremental Search

    In the olden days of computing, software flow control with control codes XON and XOFF was a necessary feature that dumb terminals needed to support. When a terminal received more data than it could display, there needed to be a way for the terminal to tell the remote host to pause sending more data. The control code 19 was chosen for this. The control code 17 was chosen to tell the remote host to resume transmission of data.

  • Raspberry Pi Pico Used in Plug and Play System Monitor | Tom's Hardware

    Dmytro Panin is at it again, creating a teeny system monitor for his MacBook from scratch with help from our favorite microcontroller, the Raspberry Pi Pico. This plug-and-play system monitor (opens in new tab) lets him keep a close eye on resource usage without having to close any windows or launch any third-party programs. The device is Pico-powered and plugs right into the MacBook to function. It has a display screen that showcases a custom GUI featuring four bar graphs that update in real-time to show the performance of different components, including the CPU, GPU, memory, and SSD usage. It makes it possible to see how hard your PC is running at a glance.
