2019 National Internet Segment Sustainability Survey

This study explains how the failure of one autonomous system (AS) affects the global connectivity of a particular region, especially when it comes to the largest Internet service provider (ISP) in that country. Internet connectivity at the network level is driven by interactions between autonomous systems. As the number of alternative routes between ASs increases, fault tolerance and stability increases […]

Something else: Haiku app bundles?

TL;DR: Can Haiku get proper support for application packages, such as application directories (like .app on Mac) and/or application images (Linux AppImage)? I think this would be a worthy addition that is easier to implement correctly than other systems since most of the infrastructure is already in place. A week ago I discovered Haiku, an unexpectedly good system. Well, since [...]

How did the Cossacks get the GICSP certificate?

Hi all! Everyone’s favorite portal had many different articles on certification in the field of information security, so I’m not going to claim originality and uniqueness of the content, but I would still really like to share my experience of obtaining GIAC (Global Information Assurance Company) certification in the field of industrial cybersecurity. Since the appearance of such terrible words as Stuxnet, Duqu, Shamoon, Triton, […]

Duqu is a malicious matryoshka

Introduction On September 1, 2011, a file named ~DN1.tmp was sent from Hungary to the VirusTotal website. At that time, the file was detected as malicious by only two antivirus engines - BitDefender and AVIRA. This is how the story of Duqu began. Looking ahead, it must be said that the Duqu malware family was named after the name of this file. However, this file is completely independent […]

Data Art Museum. KUVT2 - study and play

At the beginning of the school year, we decided to talk about one of the exhibits from our collection, the image of which remains an important memory for thousands of schoolchildren in the 1980s. The eight-bit Yamaha KUVT2 is a Russified version of the MSX standard household computer, launched in 1983 by the Japanese branch of Microsoft. Such, in fact, gaming platforms based on Zilog Z80 microprocessors have captured Japan, Korea and China, but almost […]

Most difficult program

From the translator: I found a question on Quora: What program or code can be called the most complex ever written? The answer of one of the participants was so good that it is quite worthy of an article. Fasten your seat belts. The most complex program in history was written by a team of people whose names we do not know. This program is a computer worm. The worm was written, judging by [...]

Warshipping is a cyber-threat that arrives via regular mail.

For example, techniques we've seen this year include injecting malicious code into thousands of e-commerce sites to steal personal data and using LinkedIn to install spyware. What's more, these techniques work: losses from cybercrime reached $2018 billion in 45. […]

Major update to KDE Konsole

KDE has greatly upgraded the console! One of the most significant changes in KDE Applications 19.08 was the update to the KDE terminal emulator, Konsole. Now it is able to separate tabs (horizontally and vertically) into any number of separate panels that can be freely moved between each other, creating the workspace of your dreams! Of course, we are still far from a full replacement for tmux, but KDE in […]
