Ransomware malware such as Reveton, Urausy, Tobfy, and Kovter has cost consumers considerable time and money over the past several years. Ransomware prevents victims from using their computer normally e. These consequences, such as owing a fine or facing arrest and prosecution, are presented as being the result of a fabricated indiscretion like pirating music or downloading illegal pornography. Victims of these traditional forms of ransomware could ignore the demands and use security software to unlock the system and remove the offending malware. CryptoLocker changes this dynamic by aggressively encrypting files on the victim's system and returning control of the files to the victim only after the ransom is paid. The earliest CryptoLocker samples appear to have been released on the Internet on September 5, Details about this initial distribution phase are unclear, but it appears the samples were downloaded from a compromised website located in the United States, either by a version of CryptoLocker that has not been analyzed as of this publication, or by a custom downloader created by the same authors. Early versions of CryptoLocker were distributed through spam emails targeting business professionals as opposed to home Internet users.

An effective method for filtering high frequency power supply noise and cleanly sharing similar voltage supply rails that is, analog and digital rails for mixed-signal ICs while preserving high frequency isolation between the shared rails is the use of ferrite beads. A ferrite bead is a passive device that filters high frequency noise energy over a broad frequency range. It becomes resistive over its intended frequency range and dissipates the noise energy in the form of heat. The ferrite bead is connected in series with the power supply rail and is often combined with capacitors to ground on either side of the bead. This forms a low-pass filter network, further reducing the high frequency power supply noise. However, improper use of ferrite beads in system design can lead to some detrimental issues. Some examples are unwanted resonance due to combining the bead with a decoupling capacitor for low-pass filtering and the effect of dc bias current dependency that degrades the EMI suppression capability of the bead. With proper understanding and consideration of the ferrite bead's behavior, these issues can be avoided. This article discusses the important considerations that system designers need to be aware of when using ferrite beads in power supply systems such as impedance vs. Ultimately, to address the issue on the unwanted resonance, damping techniques will be introduced and a comparison of the effectiveness of each damping method will be presented.
