GPU-powered Akira ransomware decryptor released on GitHub
Security researcher Yohanes Nugroho has released a decryptor for the Linux variant of Akira ransomware, which utilizes GPU power to retrieve the decryption key and unlock files for free. Nugroho developed the decryptor after being asked for help from a friend, deeming the encrypted system solvable within a week, based on how Akira generates encryption […]
New Chirp tool uses audio tones to send messages between devices
A new open-source tool named ‘Chirp’ transmits data, such as text messages, between computers (and smartphones) through different audio tones. The tool, developed by cybersecurity researcher solst/ICE, maps each character into a specific sound frequency and plays it along with real-time visualization. Other microphone-equipped computers running Chirp may capture the sound and translate the message back into […]
Open-source tool ‘Rayhunter’ helps users detect Stingray attacks
The Electronic Frontier Foundation (EFF) has released a free, open-source tool named Rayhunter that is designed to detect cell-site simulators (CSS), also known as IMSI catchers or Stingrays. Stingray devices mimic legitimate cell towers to trick phones into connecting, allowing them to capture sensitive data, accurately geolocate users, and potentially intercept communications. With the release […]
Apiiro unveils free scanner to detect malicious code merges
Security researchers at Apiiro have released two free, open-source tools designed to detect and block malicious code before they are added to software projects to curb supply chain attacks. The two tools consist of a comprehensive ruleset for Semgrep and Opengrep designed to detect malicious code patterns with minimal false positives and PRevent, a GitHub-integrated scanner, […]
New OpenSSH flaws expose SSH servers to MiTM and DoS attacks
OpenSSH has released security updates addressing two vulnerabilities, a machine-in-the-middle (MitM) and a denial of service flaw, with one of the flaws introduced over a decade ago. Qualys discovered both vulnerabilities and demonstrated their exploitability to OpenSSH’s maintainers. OpenSSH (Open Secure Shell) is a free, open-source implementation of the SSH (Secure Shell) protocol, which provides […]
PyPI adds project archiving system to stop malicious updates
The Python Package Index (PyPI) has announced the introduction of ‘Project Archival,’ a new system that allows publishers to archive their projects, indicating to the users that no updates are to be expected. The projects will still be hosted on PyPI, and users will still be able to download them but they will see a warning […]
Laravel admin package Voyager vulnerable to one-click RCE flaw
Three vulnerabilities discovered in the open-source PHP package Voyager for managing Laravel applications could be used for remote code execution attacks. The issues remain unfixed and can be exploited against an authenticated Voyager user that clicks on a malicious link. Vulnerability researchers at SonarSource, a code quality and security company, say that they tried to report the […]
Over 660,000 Rsync servers exposed to code execution attacks
Over 660,000 exposed Rsync servers are potentially vulnerable to six new vulnerabilities, including a critical-severity heap-buffer overflow flaw that allows remote code execution on servers. Rsync is an open-source file synchronization and data transferring tool valued for its ability to perform incremental transfers, reducing data transfer times and bandwidth usage. It supports local file systems […]
GitHub projects targeted with malicious commits to frame researcher
GitHub projects have been targeted with malicious commits and pull requests, in an attempt to inject backdoors into these projects. Most recently, the GitHub repository of Exo Labs, an AI and machine learning startup, was targeted in the attack, which has left many wondering about the attacker’s true intentions. ‘Innocent looking PR’ caught injecting backdoor On Tuesday, Alex Cheema, co-founder […]
EDRSilencer red team tool used in attacks to bypass security
A tool for red-team operations called EDRSilencer has been observed in malicious incidents attempting to identify security tools and mute their alerts to management consoles. Researchers at cybersecurity company Trend Micro say that attackers are trying to integrate EDRSilencer in attacks to evade detection. “Our internal telemetry showed threat actors attempting to integrate EDRSilencer in their […]
