Full Disk Encryption (FDE) has become increasingly important in the last decades due to the evident confidentiality concerns. In most systems, encryption is provided by an operating system driver, through which the user can transparently access the encrypted disk after supplying the required keys (…

We argue that ChaCha, BLAKE2, SHA-3, and even AES have overly generous security margins: they do more rounds than are needed for their intended security levels, and therefore spend unnecessary computa...

The kind of malware designed to conceal malicious system resources (e.g. processes, network connections, files, etc.) is commonly referred to as a rootkit. This kind of malware represents a significant threat in contemporary systems. Despite the existence of kernel-space rootkits (i.e. rootkits that infect the operating system kernel), user-space rootkits (i.e. rootkits that infect the user-space operating system tools, commands and libraries) continue to pose a significant danger. However, kernel-space rootkits attract all the attention, implicitly assuming that user-space rootkits (malware that is still in existence) are easily detectable by well-known user-space tools that look for anomalies. The primary objective of this work is to answer the following question: Is detecting user-space rootkits with user-space tools futile? Contrary to the prevailing view that considers it effective, we argue that the detection of user-space rootkits cannot be done in user-space at all. Moreover, the detection results must be communicated to the user with extreme caution. To support this claim, we conducted different experiments focusing on process concealing in Linux systems. In these experiments, we evade the detection mechanisms widely accepted as the standard solution for this type of user-space malware, bypassing the most popular open source anti-rootkit tool for process hiding. This manuscript describes the classical approach to build user-space library rootkits, the traditional detection mechanisms, and different evasion techniques (it also includes understandable code snippets and examples). In addition, it offers some guidelines to implement new detection tools and improve the existing ones to the extent possible.
