Hello! Our third book has been released, and in the comments to the post, you asked why we need a publishing house. In our case, it’s double the reason, because we deal with print and have a distribution network—so why then a publisher? The answers are quite obvious on the surface—well, this isn’t our business. But if we dig deeper, […]
Before reading this article, it is recommended to familiarize yourself with the previous article: Audio over Bluetooth: a comprehensive overview of profiles, codecs, and devices.

Good day. In my last article, I touched upon the topic of tabletop role-playing contests, which, like various indie jams for software developers, help concepts and drafts evolve into something greater. This time, I will talk about the history of another of my contest projects. I have encountered tabletop role-playing contests both domestically (called 'Kashevar') and internationally (the annual Game Chef). At the international contest, like […]
For many years, optical media has been the basis for data transmission. It is hard to imagine a reader unfamiliar with these technologies, however, it is impossible to proceed in my series of articles without at least a brief description. Contents of the series of articles: Part 1: General architecture of the CATV network Part 2: Composition and form of the signal Part 3: Analog component of the signal Part 4: Digital component of the signal […]

In this article, we will discuss the basics of capturing and analyzing SIP traffic generated by the 3CX phone system. The article is aimed at novice system administrators or regular users whose responsibilities include managing telephony. For a deeper dive into the topic, we recommend taking the Advanced 3CX training course. 3CX V16 allows for SIP traffic capture directly through the server's web interface and saves it in the standard Wireshark PCAP format.

Due to the widespread release of smartphones without a 3.5 mm audio jack, wireless Bluetooth headphones have become the primary way for many to listen to music and communicate in headset mode. Manufacturers of wireless devices do not always provide detailed product specifications, and articles about Bluetooth audio on the internet are often contradictory, at times incorrect, fail to cover all features, and frequently replicate the same inaccurate information […]

A group of researchers from Ledger, a company that produces hardware wallets for cryptocurrency, has discovered several vulnerabilities in Hardware Security Module (HSM) devices that could be exploited to extract keys or conduct remote attacks to tamper with HSM device firmware. Currently, the report on this issue is only available in French, with an English version planned for publication in August during the Blackhat conference […]
Note from the translator: The author of the original note, published on June 1, decided to conduct an experiment among those interested in information security. For this, he prepared a fake exploit for an undisclosed vulnerability in a web server and posted it on his Twitter. His assumptions — to be instantly exposed by specialists who would see the obvious deception in the code — not only did not come true… They exceeded all expectations, […]
