  • Apple patches zero-day kernel hole and much more – update now! [Ed: Apple did not patch this until it was publicly known that it had been exploited]

    The bug fixes for iPhones and iPads include remote code execution flaws (RCEs) in components from the kernel itself to Apple’s image rendering library, graphics drivers, video processing modules and more. Several of these bugs warn that “a malicious application may be able to execute arbitrary code with kernel privileges”. That’s the sort of security hole that could lead to a complete device takeover – what’s known in the jargon as a “jailbreak“, because it escapes from Apple’s strict lockdown and app restrictions.

  • Creating our own password manager

    We can manage a range of passwords by creating our own password manager using the bash commandline available in popular GNU/Linux operating systems. The GNU/Bash Shell is readily available in Ubuntu/Debian based Linux systems. They can be launched using the terminal application (with the shortcut Ctrl+Alt+T).

  • Conti presses Costa Rica. Bluetooth LE proof-of-concept. Making initial access more difficult. Cyber phases of hybrid wars. [Ed: Costa Rica pays a huge price for being penetrated by Microsoft]

    Reuters reports that the number of Costa Rican organizations affected by Conti's ransomware attack has now grown to twenty-seven. Recently elected President Rodrigo Chaves has said that nine institutions, most of them governmental, were heavily affected, and that the attacks were having an "enormous" impact on foreign trade and tax collection. The governments of Israel, the United States and Spain are all providing Costa Rica with assistance in recovery and remediation, but a lot of work remains to be done.

  • Venezuelan cardiologist charged with 'designing and selling ransomware' [Ed: Microsoft Windows]

    The US Attorney’s Office has charged a 55-year-old cardiologist with creating and selling ransomware and profiting from revenue-share agreements with criminals who deployed his product.

    A complaint [PDF] filed on May 16th in the US District Court, Eastern District of New York, alleges Moises Luis Zagala Gonzalez – aka “Nosophoros,” “Aesculapius” and “Nebuchadnezzar” – created a ransomware builder known as “Thanos”, and ransomware named “Jigsaw v. 2”.

    The self-taught coder and qualified cardiologist advertised the ransomware in dark corners of the web, then licensed it ransomware to crooks for either $500 or $800 a month, it is claimed. He also ran an affiliate network that offered the chance to run Thanos to build custom ransomware, in return for a share of profits, it is alleged.

  • How crooks backdoor sites and scrape credit card info • The Register

    In a paper scheduled to appear at the Usenix '22 security conference later this year, authors Asuman Senol (imec-COSIC, KU Leuven), Gunes Acar (Radboud University), Mathias Humbert (University of Lausanne) and Frederik Zuiderveen Borgesius, (Radboud University) described how they measured data handling in web forms on the top 100,000 websites, as ranked by research site Tranco. ®

  • Meet Wizard Spider, the multimillion-dollar gang behind Conti, Ryuk malware [Ed: Microsoft Windows]

    There also is a custom hash-cracking system that "stores cracked hashes, updates threat actors on the cracking status and shows the results of cracking attempts on other servers," the threat hunters wrote. The software claims it can crack a broad array of common hash types, including LM:NTLM hashes, cached domain credentials, Kerberos 5 TGS-REP/AS-REP tickets, KeePass files, and those used for MS Office 2013 documents.

  • Pentester pops open Tesla Model 3 using low-cost Bluetooth module

    Tesla Model 3 and Y owners, beware: the passive entry feature on your vehicle could potentially be hoodwinked by a relay attack, leading to the theft of the flash motor.

    Discovered and demonstrated by researchers at NCC Group, the technique involves relaying the Bluetooth Low Energy (BLE) signals from a smartphone that has been paired with a Tesla back to the vehicle. Far from simply unlocking the door, this hack lets a miscreant start the car and drive away, too.

  • India slightly softens infosec incident reporting rules • The Register

    India has slightly softened its controversial new reporting requirements for information security incidents and made it plain they apply to multinational companies.

    The rules were announced with little advance warning in late April and quickly attracted criticism from industry on grounds including the requirement to report 22 different types of incident within six hours, a requirement to register personal details of individual VPN users, and retention of many log files for 180 days.

  • How to choose a certificate management tool

    Managing certificates that hold all your encryption secrets is impossible without the right tool. Here's how to narrow the field.

  • OpenSSF Helping to Secure Open Source Software [Ed: No, it is mostly a marketing (openwashing) facade for proprietary software companies that actively insert back doors into things and strive to centralise everything around themselves under the guise of "security"]
  • Sigstore Sets Out to Secure Cloud-Native Supply Chain [Ed: No, this is about outsourcing trust and centralising it around Pentagon-connected companies in the name of so-called 'security' (it's censorship of software)]
  • SBOM Everywhere: The OpenSSF Plan for SBOMs [Ed: Missing disclosure here about LF paying for puff pieces about its programs and schemes]
  • Patch your VMware gear now – or yank it out, Uncle Sam tells federal agencies [Ed: When VMWare points the finger at Linux it's a deflection tactic]
  • Malicious PyPI package opens backdoors on Windows, Linux, and Macs [Ed: It's not an OS issue but an issue of people installing malware on their OS]

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
