Warrant Canary
A warrant canary is a method by which a communications service provider aims to inform its users that the provider has been served with a government subpoena despite legal prohibitions on revealing the existence of the subpoena. The warrant canary typically informs users that there has been a court-issued subpoena as of a particular date. If the canary is not updated for the period specified by the host or if the warning is removed, users might assume the host has been served with such a subpoena. The intention is for a provider passively to warn users of the existence of a subpoena, albeit violating the spirit of a court order not to do so, while not violating the letter of the order. Some subpoenas, such as those covered under 18 U.S.C. §2709(c) (enacted as part of the USA Patriot Act), provide criminal penalties for disclosing the existence of the subpoena to any third party, including the service provider's users. National Security Letters (NSL) originated in the 1986 Ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IMAP
In computing, the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection. IMAP is defined by . IMAP was designed with the goal of permitting complete management of an email box by multiple email clients, therefore clients generally leave messages on the server until the user explicitly deletes them. An IMAP server typically listens on port number 143. IMAP over SSL/TLS (IMAPS) is assigned the port number 993. Virtually all modern e-mail clients and servers support IMAP, which along with the earlier POP3 (Post Office Protocol) are the two most prevalent standard protocols for email retrieval. Many webmail service providers such as Gmail and Outlook.com also provide support for both IMAP and POP3. Email protocols The Internet Message Access Protocol is an application layer Internet protocol that allows an e-mail client to access email on a remote mail server. The curr ...

Ransomware
Ransomware is a type of malware from cryptovirology that threatens to publish the victim's personal data or permanently block access to it unless a ransom is paid off. While some simple ransomware may lock the system without damaging any files, more advanced malware uses a technique called cryptoviral extortion. It encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as paysafecard or Bitcoin and other cryptocurrencies are used for the ransoms, making tracing and prosecuting the perpetrators difficult. Ransomware attacks are typically carried out using a Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the WannaCry worm, traveled automat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denial-of-service Attack
In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack, as simply attempting to block a single source is insufficient because there are multiple sources. A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade. Criminal perpetrators of DoS attacks oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Bureau Of Investigation
The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States and its principal federal law enforcement agency.

Anarchism
Anarchism is a political philosophy and movement that is skeptical of all justifications for authority and seeks to abolish the institutions it claims maintain unnecessary coercion and hierarchy, typically including, though not necessarily limited to, governments, nation states, and capitalism. Anarchism advocates for the replacement of the state with stateless societies or other forms of free associations. As a historically left-wing movement, usually placed on the farthest left of the political spectrum, it is usually described alongside communalism and libertarian Marxism as the libertarian wing (libertarian socialism) of the socialist movement. Humans lived in societies without formal hierarchies long before the establishment of formal states, realms, or empires. With the rise of organised hierarchical bodies, scepticism toward authority also rose. Although traces of anarchist thought are found throughout history, modern anarchism emerged from the Enlightenment. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bash Back!
Bash Back! was a network of queer, Insurrectionary anarchism, insurrectionary anarchist cells active in the United States between 2007 and 2011. Formed in Chicago in 2007 to facilitate a convergence of radical trans and gay activists from around the country, Bash Back! sought to critique the ideology of the mainstream LGBT movement, which the group saw as Cultural assimilation, assimilation into the dominant institutions of a heteronormative society. Bash Back! was noticeably influenced by the anarchist movement and radical queer groups, such as ACT UP, and took inspiration from the Stonewall riots, Stonewall and San Francisco's White Night riots. The group arose out of anti–Republican National Convention and anti–Democratic National Convention organizing, and continued up to 2011. Chapters sprang up across the country, including in Philadelphia and Seattle. The organization's model was a nonhierarchical autonomous network based on agreed-upon points of unity, such as fight ...
