Stegano

Stegano Stegano, a pure Python Steganography module. Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. Consequently, functions provid...

A Novel APVD Steganography Technique Incorporating Pseudorandom Pixel Selection for Robust Image Security

Steganography is the process of embedding secret information discreetly within a carrier, ensuring secure exchange of confidential data. The Adaptive Pixel Value Differencing APVD steganography method, while effective, encounters certain challenges like the "unused blocks" issue. This problem can...

Joint Data Hiding and Partial Encryption of Compressive Sensed Streams

The paper proposes a method to secure the Compressive Sensing CS streams. It consists in protecting part of the measurements by a secret key and inserting the code into the rest. The secret key is generated via a cryptographically secure pseudo-random number generator CSPRNG and XORed with the...

Code injection

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...

RFC 9000 Security Vulnerabilities

RFC 9000 is a protocol for the fast and secure transmission of data over the Internet. A security vulnerability exists in RFC 9000 that originated to allow a remote attacker to construct a covert channel using data represented as bit-value changes to hide or embed data in seemingly normal network...

Too Log; Didn't Read — Unknown Actor Using CLFS Log Files for Stealth

50m-ctf: LFI on Accounting server and RCE on FliteThermostat admin server

Summary: An attacker is able to download local files on the Accounting server due leveraging improper input sanitization in the Invoice PDF generator. In the same fashion an attacker is also able to issue server-side requests on the Accounting server through user-controlled CSS, possibly leading ...

S3QL Replay Attack Vulnerability

S3QL is a file system for storing online data. The system supports Amazon S3, SFTP servers, and more. A security vulnerability exists in the 'checksumbasicmapping' function in S3QL versions prior to 2.27. An attacker can exploit the vulnerability to display an old version of the metadata database...

UBUNTU-CVE-2018-12088

S3QL before 2.27 mishandles checksumming, and consequently allows replay attacks in which an attacker who controls the backend can present old versions of the filesystem metadata database as up-to-date, temporarily inject zero-valued bytes into files, or temporarily hide parts of files. This is...
