Favicon Trojans: Executable Steganography Via Ico Alpha Channel Exploitation

This paper presents a novel method of executable steganography using the alpha transparency layer of ICO image files to embed and deliver self-decompressing JavaScript payloads within web browsers. By targeting the least significant bit LSB of non-transparent alpha layer image values, the propose...

SmartAttack: Air-Gap Attack Via Smartwatches

Air-gapped systems are considered highly secure against data leaks due to their physical isolation from external networks. Despite this protection, ultrasonic communication has been demonstrated as an effective method for exfiltrating data from such systems. While smartphones have been extensivel...

The npm package ts-runtime-compat-check is a malicious package that functions as a key component in a remote code execution attack chain. This package: 1. Contains a postinstall script that executes lib/install.js 2. The install script makes HTTP requests to a server specified by an environment...

State Injection Into Hardware Prefetchers

Bulletin ID: AMD-SB-7023 Potential Impact: Data leakage via Side Channels Severity: N/A Summary A research paper titled ‘ ShadowLoad: Injecting State into Hardware Prefetchers ’ was provided to AMD in February 2024. The paper discusses the possibility for prefetchers to be used to inject cache...

SharpCovertTube - Youtube As Covert-Channel - Control Windows Systems Remotely And Execute Commands By Uploading Videos To Youtube

SharpCovertTube is a program created to control Windows systems remotely by uploading videos to Youtube. The program monitors a Youtube channel until a video is uploaded, decodes the QR code from the thumbnail of the uploaded video and executes a command. The QR codes in the videos can use...

CVE-2023-50923

In QUIC in RFC 9000, the Latency Spin Bit specification section 17.4 does not strictly constrain the bit value when the feature is disabled, which might allow remote attackers to construct a covert channel with data represented as changes to the bit value. NOTE: The "Sheridan, S., Keane, A. 2015...

SLAM Attack: New Spectre-based Vulnerability Impacts Intel, AMD, and Arm CPUs

Researchers from the Vrije Universiteit Amsterdam have disclosed a new side-channel attack called SLAM that could be exploited to leak sensitive information from kernel memory on current and upcoming CPUs from Intel, AMD, and Arm. The attack is an end-to-end exploit for Spectre based on a new...

x86/AMD: Divide speculative information leak

ISSUE DESCRIPTION In the Zen1 microarchitecure, there is one divider in the pipeline which services uops from both threads. In the case of DE, the latched result from the previous DIV to execute will be forwarded speculatively. This is a covert channel that allows two threads to communicate witho...

COVID-bit: New COVert Channel to Exfiltrate Data from Air-Gapped Computers

An unconventional data exfiltration method leverages a previously undocumented covert channel to leak sensitive information from air-gapped systems. "The information emanates from the air-gapped computer over the air to a distance of 2 m and more and can be picked up by a nearby insider or spy wi...

Air-Gapped Devices Can Send Covert Morse Signals via Network Card LEDs

A security researcher who has a long line of work demonstrating novel data exfiltration methods from air-gapped systems has come up with yet another technique that involves sending Morse code signals via LEDs on network interface cards NICs. The approach, codenamed ETHERLED, comes from Dr...
