Moments later, the laptop bypassed Windows entirely, booting into IGEL OS , an ultra-lightweight, hardened Linux environment that ran exclusively from the encrypted thumb drive. Technical Advantages - Immutable OS architecture: The operating system runs from a read-only partition.
Encryption Technologies: Encryption protects data confidentiality and integrity, but attackers also use it to conceal malware, establish encrypted communication channels, and secure stolen data. However, defenders use the cloud to implement security measures, such as IAM controls and encryption.
Their report is a good starting point for diving deep into the MBUX internals and understanding the architecture of the system. Full information on the MBUX architecture can be found in the KeenLab research. Besides metadata in plaintext, they also contain encrypted data, which the diagnostic tool uses its shared libraries to decrypt.
Double extortion ransomware is now a preferred techniquea devastating one-two punch where attackers not only encrypt a companys data but also steal sensitive information. An insider unknowingly clicking a phishing link or downloading a malicious file could leave the door wide open for attackers.
Our architecture, developed in the defense and intelligence community, was designed for this complexity from day one. This includes passing an architecture review grounded in AWS Well-Architected Frameworks. This includes passing an architecture review grounded in AWS Well-Architected Frameworks.
Our in-depth analysis of the malware revealed a sophisticated, multi-functional backdoor that can be dynamically extended with arbitrary functionality through the download of additional modules. It acts as a C2 command parser, capable of executing shellcode, downloading files, running commands, and loading additional.NET byte code.
ESET researchers discovered a new downloader, dubbed DePriMon, that used new “Port Monitor” methods in attacks in the wild. . The new DePriMon downloader was used by the Lambert APT group, aka Longhorn, to deploy malware. The second stage installs itself and loads the third stage using an encrypted, hardcoded path.
