Many people on the Pwnie Express website have developed a variety of hacking tools that are "polished" to look like office supplies, such as power plugs and printer plugs. Most of the tools made by these people can be accessed through LAN,496 Chapter 14 Security Evasion TechniquesWireless networks and VPN technology, with various forms of encryption to access the compromised network and ultimately achieve their ulterior motivespurposes. oThe Pwnie Express team can even provide Raspberry Pi (Raspberry Pi) images that transform the Raspberry Pi intoremotely accessible penetration tool for under $50.Another layer of encryption is hiding the actual data. There are a number of technologies that can do this, and several enterprise file encryption technologies can encrypt files and control access to open them. Let's say that a software agent is installed on the server that indicates which files should be encrypted. When the files that should be encrypted are deleted, the software agent marks and encrypts the files and provides access only to those who belong to the designated authentication group. Persons belonging to that authentication group can use the host-based agent that automatically logs them into the file, or they can send them to the online portal for authentication to gain access to the file.The term "data at rest" refers to data stored in a storage medium. The static data security requirement (data.at.rest security requirement) generally means that all access to stored data should be terminated whenever the data is considered sensitive and at risk of exposure. To satisfy that requirement, there is often a method of first encrypting the data and then subsequently deleting all decrypted data. Let's say, for example, encrypting a hard drive so that it cannot be cloned. The same concept also applies to file encryption techniques one-by-one according to which the owner can disable access to the file, meaning that all users will not be able to decrypt the data.Many attackers exploit encryption (e.g., file encryption and protocol encryption) for the purpose of hiding malicious code.
