HELO Cryptography: A Lightweight Cryptographic System for Enhancing IoT Security in P2P Data Transmission

The recent surge in security concerns for IoT devices highlights the increasing threat of cryptographic vulnerabilities. These weaknesses can lead to unauthorized access, data breaches, and manipulation of device functions, compromising the privacy and security of both the devices and their users...

Malicious code in @fairwords/websocket (npm)

The @fairwords/websocket package was compromised as part of the TeamPCP/CanisterWorm campaign. A postinstall hook executes node scripts/check-env.js || true which performs multi-stage credential harvesting, encrypted exfiltration, and self-propagation. The payload harvests 40+ environment variabl...

Advanced Python Payload Encryption Framework with Hybrid Cryptography Steganography and Anti‑Debugging

This Python program implements an advanced payload protection framework that combines multiple security and obfuscation techniques to encrypt, package, and distribute Python code. The framework supports hybrid encryption, multi‑key protection, anti‑debugging checks, and optional steganographic...

RUSTSEC-2026-0071 Nonce Reuse in HPKE Context

The sequence number that is used to compute the AEAD nonce when using a re-usable HPKE context is incremented after each seal or open operation. This sequence number was stored as a u32 and used regular addition on u32 for the increment, meaning in release mode it would silently wrap around to 0...

CVE-2025-64767 hpke-js reuses AEAD nonces

hpke-js is a Hybrid Public Key Encryption HPKE module built on top of Web Cryptography API. Prior to version 1.7.5, the public SenderContext Seal API has a race condition which allows for the same AEAD nonce to be re-used for multiple Seal calls. This can lead to complete loss of Confidentiality...

DEBIAN-CVE-2014-6274

git-annex had a bug in the S3 and Glacier remotes where if embedcreds=yes was set, and the remote used encryption=pubkey or encryption=hybrid, the embedded AWS credentials were stored in the git repository in effectively plaintext, not encrypted as they were supposed to be. This issue affects...

SECNEURON: Reliable and Flexible Abuse Control in Local LLMs Via Hybrid Neuron Encryption

Large language models LLMs with diverse capabilities are increasingly being deployed in local environments, presenting significant security and controllability challenges. These locally deployed LLMs operate outside the direct control of developers, rendering them more susceptible to abuse...

Lightweight Hybrid Block-Stream Cryptographic Algorithm for the Internet of Things

In this thesis, a novel lightweight hybrid encryption algorithm named SEPAR is proposed, featuring a 16-bit block length and a 128-bit initialization vector. The algorithm is designed specifically for application in Internet of Things IoT technology devices. The design concept of this algorithm i...

Vice Society Ransomware Using Stealthy PowerShell Tool for Data Exfiltration

Threat actors associated with the Vice Society ransomware gang have been observed using a bespoke PowerShell-based tool to fly under the radar and automate the process of exfiltrating data from compromised networks. "Threat actors TAs using built-in data exfiltration methods like living off the...

Baphomet - Basic Concept Of How A Ransomware Works

This is a proof of concept of how a ransomware works, and some techniques that we usually use to hijack our files. This project is written in C using the net-core application framework 3.1.The main idea of the code is to make it as readable as possible so that people have an idea of how this type...
