  • Kerckhoffs’s Law for Security Engineers

    One of the first lessons in cryptography 101 is Kerckhoffs’s law: a cryptosystem should be secure even if everything about the system, except the key, is public knowledge. This is an often-repeated maxim accompanied with “there is no security with obscurity.”

    I always found this framing confusing: it felt inconsistent within itself. “don’t rely on secrecy except for the secrecy of the key” What is so special about keys? Why is it ok to rely on the secrecy of keys and not on secrecy of anything else? And because it is so focused on keys, it’s hard to really take this foundational lesson and apply it in contexts other than cryptographic algorithms.

  • How A New Team Of Feds [Cracked] The [Crackers] And Got Colonial Pipeline's Ransom Back [iophk: Windows TCO]

    Court documents released in the Colonial Pipeline case say the FBI got in by using the encryption key linked to the Bitcoin account to which the ransom money was delivered. However, officials have not disclosed how they got that key. One of the reasons criminals like to use Bitcoin and other cryptocurrencies is the anonymity [sic] of the entire system, as well as the idea that funds in any given cryptocurrency wallet can be accessed only with a complex digital key.

  • How a Fake FBI-Encrypted Device Ensnared Criminals Around the World

    Australian media reported that the country's most wanted fugitive, Hakan Ayik, was given early access to the device by undercover agents and unwittingly promoted ANOM to his associates.

    Demand for the messaging app grew when European investigators dismantled the popular EncroChat encrypted platform in July 2020. And usage exploded when the FBI dismantled Sky Global, another encrypted platform, in March 2021, officials said.

  • Police in 16 countries have arrested hundreds following a massive sting

    Operation Trojan Shield is the most wide-ranging attack on underworld communications, but not the first. Last year, the EU’s law enforcement agency, Europol, revealed that an operation initiated by French police had [cracked] a system known as EncroChat, which many criminals used. The [crack] has led police to arrest more than 1,000 people so far.

  • Hundreds arrested around the world in huge global organized crime sting

    ANOM's users believed the devices to be secure, according to Jannine van den Berg of the Dutch National Police at the press conference. Access to the communications of those involved in criminal networks meant that law enforcement agencies were able to read encrypted messages.

  • The Criminals Thought the Devices Were Secure. But the Seller Was the F.B.I.

    For years, organized crime figures around the globe relied on the devices to orchestrate international drug shipments, coordinate the trafficking of arms and explosives, and discuss contract killings, law enforcement officials said. Users trusted the devices’ security so much that they often laid out their plans not in code, but in plain language.

    b Unbeknown to them, the entire network was run by the F.B.I., in coordination with the Australian police.

    On Tuesday, global law enforcement officials revealed the three-year operation, in which they said they had intercepted over 20 million messages, and arrested at least 800 people in more than a dozen countries.

  • 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.
