Detecting Covert Channels Through Code Augmentation [PDF]

, 2021
Modern malware increasingly exploits information hiding or steganography to elude security frameworks and remain unnoticed for long periods. To this aim, a prime technique relies upon the ability of creating covert channels to bypass the limits imposed by a sandbox or to exfiltrate data towards a remote server. Unfortunately, detecting a covert channel

Inaudible sound covert channel with anti-jamming capability: Attacks vs. countermeasure

Journal of Electronic Science and Technology, 2022
When an inaudible sound covert channel (ISCC) attack is launched inside a computer system, sensitive data are converted to inaudible sound waves and then transmitted.

Detection of Covert Timing Channel Based on Time Series Symbolization

IEEE Open Journal of the Communications Society, 2021
Covert Timing Channels(CTCs) is a technique to leak information. CTCs only modify inter-arrival time sequence(IATs) between packets, consequently, traditional network security mechanisms, such as firewalls and proxies, can not effectively detect CTCs. If

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
