CVE-2025-14505 is a medium-severity vulnerability in the Elliptic package's ECDSA implementation, where an incorrect computation of the byte-length of the ephemeral value 'k' leads to truncation when 'k' has leading zeros. This flaw causes faulty digital signatures and breaks legitimate transactions or communications. More critically, attackers who obtain both a faulty signature and a correct signature for the same input under certain conditions may derive the secret private key, compromising cryptographic confidentiality. The vulnerability affects all Elliptic versions up to and including 6.6.1. Exploitation requires network access but no privileges or user interaction, and no known exploits are currently in the wild. European organizations relying on Elliptic for cryptographic operations, especially in financial or blockchain applications, face risks of transaction failures and potential key compromise. Mitigation involves updating to a patched Elliptic version once available, auditing signature generation for anomalies, and implementing additional cryptographic safeguards. Countries with significant blockchain, fintech, and cryptography-dependent sectors such as Germany, the UK, France, and the Netherlands are most likely to be impacted.
ASEC discovered Guloader malware being distributed through phishing emails masquerading as employee performance reports. The emails, claiming to be about October 2025 performance, contain a RAR file with an NSIS executable named 'staff record pdf.exe'. This file is actually Guloader malware, which downloads and executes shellcode from a Google Drive URL. The final payload is Remcos RAT, enabling threat actors to perform various malicious remote control activities, including keylogging, screenshot capture, webcam and microphone control, and browser data extraction. The attackers are increasingly using legitimate platforms as C2 servers, making detection more challenging. Users are advised to exercise caution when opening emails from unknown sources and to change passwords regularly to prevent secondary damage.
The Boto Cor-de-Rosa campaign reveals Astaroth's new strategy of exploiting WhatsApp Web for propagation. This Brazilian banking malware now uses a Python-based worm module to retrieve victims' WhatsApp contact lists and automatically send malicious messages, expanding its infection reach. The attack begins with a malicious ZIP file sent via WhatsApp, containing a Visual Basic script that downloads additional components. The malware then operates two parallel modules: a propagation module for spreading through WhatsApp contacts, and a banking module for credential stealing. This campaign demonstrates Astaroth's evolution, combining traditional malware techniques with sophisticated social engineering and multi-platform propagation, primarily targeting Brazilian users.
MuddyWater APT group has launched a spearphishing campaign targeting various sectors in the Middle East, including diplomatic, maritime, financial, and telecom entities.
