The prevalence of malware infection by means of USB flash drive was documented in a 2011 Microsoft study [6] analyzing data from more than 600 million systems worldwide in the first half of 2011. The study found that 26 percent of all malware infections of Windows system were due to USB flash drives exploiting the AutoRun feature in Microsoft ...
Kon-Boot was originally designed as a proof of concept, freeware security tool, mostly for people who tend to forget their passwords. The main idea was to allow users to login to the target computer without knowing the correct password and without making any persistent changes to system on which it is executed.
On Windows Vista and later it requires an elevated-privileges command prompt (see User Account Control). The target drive must be connected to a physical disk controller. The software will not work when using a hard drive through an external connection like USB or any external hard drive. Display detected Hard Drives: ATATOOL /LIST
USB Key Mode: The user must insert a USB device that contains a startup key into the computer to be able to boot the protected OS. Note that this mode requires that the BIOS on the protected machine supports the reading of USB devices in the pre-OS environment.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
There are potential weaknesses in the implementation of the protocol between the dongle and the copy-controlled software. For example, a simple implementation might define a function to check for the dongle's presence, returning "true" or "false" accordingly, but the dongle requirement can be easily circumvented by modifying the software to always answer "true".
When a computer with a self-encrypting drive is put into sleep mode, the drive is powered down, but the encryption password is retained in memory so that the drive can be quickly resumed without requesting the password. An attacker can take advantage of this to gain easier physical access to the drive, for instance, by inserting extension cables.
Screenshot of the Syskey utility on the Windows 8.1 operating system requesting the user to enter a password.. The SAM Lock Tool, better known as Syskey (the name of its executable file), is a discontinued component of Windows NT that encrypts the Security Account Manager (SAM) database using a 128-bit RC4 encryption key.
