It's time to demonstrate how the cryptographic ARM based on public key standards cryptoarmpkcs works on one of the mobile platforms, namely Android. The concept laid out during the development of the cryptoarmpkcs utility is that the user should experience minimal inconvenience when creating and verifying electronic signatures. That's why we propose as the key carrier for the personal certificate […]
A vulnerability (CVE-2020-0556) has been discovered in the open Bluetooth stack BlueZ, which is used in Linux distributions and Chrome OS, potentially allowing an attacker to access the system. Due to improper access validation in the implementation of Bluetooth profiles HID and HOGP, the vulnerability permits denial of service or privilege escalation when connecting a malicious Bluetooth device without completing the device bonding process. The malicious Bluetooth device […]

On the evening of March 10, Mail.ru's support service began receiving complaints from users about the inability to connect to Mail.ru's IMAP/SMTP servers through mail clients. Some connections were unsuccessful, while others displayed a certificate error. This error is caused by the 'server' giving a self-signed TLS certificate. Over two days, more than 10 complaints came from users across various networks […]
Collaboration is a sore point for traditional office tools. When ten people are working on a file simultaneously, more time and effort are spent on tracking changes and their authors rather than making edits. This is complicated by numerous applications that are not always compatible. One way to address this issue is to switch to cloud-based office suites. There are not many options available, […]
Tavis Ormandy, a security researcher at Google, is developing the LoadLibrary project, aimed at porting DLL libraries compiled for Windows for use in applications on Linux. The project provides a wrapper library that allows DLL files in PE/COFF format to be loaded and specific functions within them to be called. The PE/COFF loader is based on ndiswrapper code. The project's code is distributed under the GPLv2 license. […]
A new release of the APT package manager has been issued, numbered 2.0. Changes include: Commands that accept package names now support patterns. Their syntax is similar to aptitude. Attention!

Everything we will discuss now is essential knowledge for anyone working […]
In the previous post about PDUs, we mentioned that some racks are equipped with an AVR — automatic transfer switch. However, in reality, AVRs are installed not only in racks but also along the entire electrical path in the data center. They serve different purposes in various locations: in main distribution boards, AVRs switch the load between the city input and […]
