A cybersecurity system includes a controller that functions as a gateway between an end user device and an offline data storage device. When the end user device wants to access a file on the offline data storage device the controller severs a connection between a temporary storage memory and the end user device, establishes a connection with the offline data storage device, pulls the data from the offline data storage device to a temporary storage memory, then severs the connection with the offline data storage device, then establishes the connection with the end user device and communicates the data from the temporary storage memory to the end user device before overwriting the data in the temporary storage memory.

Compiler based obfuscation is described. To protect portions of a code project with obfuscations, the code is modified within a compiler to produce one or more modifications that obfuscate the code as part of a compilation process. A compiled version of the code is generated having the modifications that are produced within the compiler. In one approach, the compiler is configured to consume an obfuscation description that indicates portions of the code to protect and specifies the modifications to make to the indicated portions. Various different modifications of code may be performed during the compilation process to implement corresponding obfuscation features. For example, the modifications made within a compiler may include, but are not limited to, modifications designed to enable tamper detection, anti-debugging, and/or encryption of the code.

Compile based obfuscation

A system, a method, and computer-readable media are provided for altering behavior of software based on detection of an Internet connection. The system, method, and media detect when a computer has connected to the Internet or is capable of connecting to the Internet. This detection may include analyzing a connection history of the computer to the Internet, reporting in real-time when the computer establishes a connection to the Internet, or attempting to actively establish a connection with an Internet resource using the computer. A first set of software functionality may be disabled when a previously established connection with the Internet is identified, a real-time report of a connection with the Internet is generated, or a connection with the Internet resource is established. In addition, a second set of software functionality may be enabled when the first set of software functionality is disabled.

Altering software behavior based on internet connectivity

A method and a processing device are provided for detecting a hardware-based virtual machine environment. An execution time of a privileged instruction may be measured and an execution time of a nonprivileged instruction may be measured. The execution time of the privileged instruction may be compared with the execution time of the nonprivileged instruction. When the execution time of the privileged instruction exceeds the execution time of the nonprivileged instruction by at least a threshold or a threshold factor, then a hardware-based virtual machine environment is detected. In some embodiments, a well-known technique for detecting a software-based virtual machine environment may be used in conjunction with a technique for detecting a hardware-based virtual machine environment. A licensing policy of a software product may be accessed and the software product may be prevented from executing when a detected machine environment is in violation of the licensing policy.
