A group of researchers from the Vrije Universiteit Amsterdam, the Swiss Federal Institute of Technology Zurich, and Qualcomm conducted a study on the effectiveness of the defense mechanisms against RowHammer attacks implemented in modern DDR4 memory chips, which can alter the contents of individual bits in dynamic RAM (DRAM). The results were disheartening, as DDR4 chips from major manufacturers remain vulnerable (CVE-2020-10255). The RowHammer vulnerability allows for the corruption of specific contents […]
On March 13, Wine 5.4 was released. Wine is a compatibility layer for running Windows applications on POSIX-compliant operating systems, translating Windows API calls to POSIX calls on the fly instead of emulating Windows logic like a virtual machine.

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 […]

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. […]
