USBKill
USBKill is anti-forensic software distributed via GitHub, written in Python for the BSD, Linux, and OS X operating systems. It is designed to serve as a kill switch if the computer on which it is installed should fall under the control of individuals or entities against the desires of the owner. It is free software, available under the GNU General Public License. The program's developer, who goes by the online name Hephaest0s, created it in response to the circumstances of the arrest of Silk Road founder Ross Ulbricht, during which U.S. federal agents were able to get access to incriminating evidence on his laptop without needing his cooperation by copying data from its flash drive after distracting him. It maintains a whitelist of devices allowed to connect to the computer's USB ports; if a device not on that whitelist connects, it can take actions ranging from merely returning to the lock screen to encrypting the hard drive, or wiping all data on the computer. However, it ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kill Switch
A kill switch, also known as an emergency stop (E-stop), emergency off (EMO) and as an emergency power off (EPO), is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usual manner. Unlike a normal shut-down switch or shut-down procedure, which shuts down all systems in order and turns off the machine without damage, a kill switch is designed and configured to abort the operation as quickly as possible (even if it damages the equipment) and to be operated simply and quickly (so that even a panicked operator with impaired executive functions or a bystander can activate it). Kill switches are usually designed to be noticeable, even to an untrained operator or a bystander. Some kill switches feature a removable, protective barrier against accidental activation (e.g. a plastic cover that must be lifted or glass that must be broken), known as a mollyguard. Kill switches are features of mechanisms whose normal operation or foreseeable mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Ulbricht
Ross William Ulbricht (born March 27, 1984) is an American serving life imprisonment for creating and operating the darknet market website Silk Road from 2011 until his arrest in 2013. The site operated as a hidden service on the Tor network and facilitated the sale of narcotics and other illegal products and services. Ulbricht ran the site under the pseudonym "Dread Pirate Roberts", after the fictional character from ''The Princess Bride.'' In 2013, the Federal Bureau of Investigation (FBI) arrested Ulbricht and Silk Road was taken offline. In 2015, he was convicted of engaging in a continuing criminal enterprise, distributing narcotics, distributing narcotics by means of the internet, conspiracy to distribute narcotics, conspiracy to commit money laundering, conspiracy to traffic fraudulent identity documents, and conspiracy to commit computer hacking. He was sentenced to a double life sentence plus 40 years without the possibility of parole. Ulbricht's appeals to the U.S. ...

Anti-computer Forensics
Anti-computer forensics or counter-forensics are techniques used to obstruct forensic analysis. Definition Anti-forensics has only recently been recognized as a legitimate field of study. Within this field of study, numerous definitions of anti-forensics abound. One of the more widely known and accepted definitions comes from Marc Rogers of Purdue University. Rogers uses a more traditional "crime scene" approach when defining anti-forensics. "Attempts to negatively affect the existence, amount and/or quality of evidence from a crime scene, or make the analysis and examination of evidence difficult or impossible to conduct."Rogers, D. M. (2005). Anti-Forensic Presentation given to Lockheed Martin. San Diego. One of the earliest detailed presentations of anti-forensics, in Phrack Magazine in 2002, defines anti-forensics as "the removal, or hiding, of evidence in an attempt to mitigate the effectiveness of a forensics investigation".The Grugq (2002). Phrack Magazine. A more abbrev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

Malware
Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. By contrast, software that causes harm due to some deficiency is typically described as a software bug. Malware poses serious problems to individuals and businesses on the Internet. According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy $6 trillion USD in 2021, and is increasing at a rate of 15% per year. Many types of malware exist, including computer viruses, worms, Trojan horses, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spyware
Spyware (a portmanteau for spying software) is software with malicious behaviour that aims to gather information about a person or organization and send it to another entity in a way that harms the user—for example, by violating their privacy or endangering their device's security. This behaviour may be present in malware as well as in legitimate software. Websites may engage in spyware behaviours like web tracking. Hardware devices may also be affected. Spyware is frequently associated with advertising and involves many of the same issues. Because these behaviors are so common, and can have non-harmful uses, providing a precise definition of spyware is a difficult task.FTC Report (2005)." History The first recorded use of the term :wikt:spyware, spyware occurred on October 16, 1995 in a Usenet post that poked fun at Microsoft's business model.Vossen, Roland (attributed); October 21, 1995Win 95 Source code in c!!posted to rec..programmer; retrieved from groups.google.co ...

Law Enforcement
Law enforcement is the activity of some members of government who act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society. The term encompasses police, courts, and corrections. These three components may operate independently of each other or collectively, through the use of record sharing and mutual cooperation. The concept of law enforcement dates back to ancient times, and forms of law enforcement and police have existed in various forms across many human societies. Modern state legal codes use the term peace officer, or law enforcement officer, to include every person vested by the legislating state with police power or authority; traditionally, anyone sworn or badged, who can arrest any person for a violation of criminal law, is included under the umbrella term of law enforcement. Although law enforcement may be most concerned with the prevention and punishment o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
No-knock Warrant
In the United States, a no-knock warrant is a warrant issued by a judge that allows law enforcement to enter a property without immediate prior notification of the residents, such as by knocking or ringing a doorbell. In most cases, law enforcement will identify themselves just before they forcefully enter the property. It is issued under the belief that any evidence they hope to find may be destroyed between the time that police identify themselves and the time they secure the area, or in the event where there is a large perceived threat to officer safety during the execution of the warrant. Use of no-knock warrants has increased substantially over time. By one estimate, there were 1,500 annually in the early 1980s whereas by 2010 there were 60,000–70,000 no-knock or quick-knock raids conducted by local police annually, the majority of which were looking for marijuana. Amid nationwide protests in response to the police killings of Breonna Taylor and George Floyd, there were e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Crime
A cybercrime is a crime that involves a computer or a computer network.Moore, R. (2005) "Cyber crime: Investigating High-Technology Computer Crime," Cleveland, Mississippi: Anderson Publishing. The computer may have been used in committing the crime, or it may be the target. Cybercrime may harm someone's security or finances. There are many privacy concerns surrounding cybercrime when confidential information is intercepted or disclosed, lawfully or otherwise. Internationally, both governmental and non-state actors engage in cybercrimes, including espionage, financial theft, and other cross-border crimes. Cybercrimes crossing international borders and involving the actions of at least one nation-state are sometimes referred to as cyberwarfare. Warren Buffett describes cybercrime as the "number one problem with mankind" and said that cybercrime "poses real risks to humanity." A 2014 report sponsored by McAfee estimated that cybercrime resulted in $445 billion in annual dama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Encryption
In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is possible to decrypt the message without possessing the key but, for a well-designed encryption scheme, considerable computational resources and skills are required. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users. Historically, various forms of encryption have been used to aid in cryptography. Early encryption techniques were often used in military ...
