Joseph Popp
AIDS, also known as Aids Info Disk or PC Cyborg Trojan, is a DOS Trojan horse whose payload mungs and encrypts the names of all directories on drive C:. It was developed by Dr. Joseph Popp, an evolutionary biologist who graduated from Harvard. The virus was isolated in 1989. Description AIDS replaces the AUTOEXEC.BAT file, which would then be used by AIDS to count the number of times the computer has booted. Once this boot count reaches 90, AIDS hides directories and encrypts the names of all files on drive C: (rendering the system unusable), at which time the user is asked to 'renew the license' and contact PC Cyborg Corporation for payment (which would involve sending US$189 to a post office box in Panama). There exists more than one version of AIDS, and at least one version does not wait to mung drive C:, but will hide directories and encrypt file names upon the first boot after AIDS is installed. The AIDS software also presented to the user an end user license agreement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trojan Horse (computing)
In computing, a Trojan horse is any malware that misleads users of its true intent. The term is derived from the Ancient Greek story of the deceptive Trojan Horse that led to the fall of the city of Troy. Trojans generally spread by some form of social engineering; for example, where a user is duped into executing an email attachment disguised to appear innocuous (e.g., a routine form to be filled in), or by clicking on some fake advertisement on social media or anywhere else. Although their payload can be anything, many modern forms act as a backdoor, contacting a controller who can then have unauthorized access to the affected computer. Ransomware attacks are often carried out using a Trojan. Unlike computer viruses and worms, Trojans generally do not attempt to inject themselves into other files or otherwise propagate themselves. Use of the term It's not clear where or when the concept, and this term for it, was first used, but by 1971 the first Unix manual assumed its r ...

AIDS Information Introductory Diskette Version 2 0 Kopiera
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged incubation period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss. HIV is spread primarily by unprotected sex (including anal and vaginal sex), contaminated blood transfusions, hypodermic needles, and from mother to child during ...

Cryptovirology
Cryptovirology refers to the use of cryptography to devise particularly powerful malware, such as ransomware and asymmetric backdoors. Traditionally, cryptography and its applications are defensive in nature, and provide privacy, authentication, and security to users. Cryptovirology employs a twist on cryptography, showing that it can also be used offensively. It can be used to mount extortion based attacks that cause loss of access to information, loss of confidentiality, and information leakage, tasks which cryptography typically prevents. The field was born with the observation that public-key cryptography can be used to break the symmetry between what an antivirus analyst sees regarding malware and what the attacker sees. The antivirus analyst sees a public key contained in the malware, whereas the attacker sees the public key contained in the malware as well as the corresponding private key (outside the malware) since the attacker created the key pair for the attack. The pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Atlantic
''The Atlantic'' is an American magazine and multi-platform publisher. It features articles in the fields of politics, foreign affairs, business and the economy, culture and the arts, technology, and science. It was founded in 1857 in Boston, as ''The Atlantic Monthly'', a literary and cultural magazine that published leading writers' commentary on education, the abolition of slavery, and other major political issues of that time. Its founders included Francis H. Underwood and prominent writers Ralph Waldo Emerson, Oliver Wendell Holmes Sr., Henry Wadsworth Longfellow, Harriet Beecher Stowe, and John Greenleaf Whittier. James Russell Lowell was its first editor. In addition, ''The Atlantic Monthly Almanac'' was an annual almanac published for ''Atlantic Monthly'' readers during the 19th and 20th centuries. A change of name was not officially announced when the format first changed from a strict monthly (appearing 12 times a year) to a slightly lower frequency. It was a mo ...

Blackmail
Blackmail is an act of coercion using the threat of revealing or publicizing either substantially true or false information about a person or people unless certain demands are met. It is often damaging information, and it may be revealed to family members or associates rather than to the general public. These acts can also involve using threats of physical, mental or emotional harm, or of criminal prosecution, against the victim or someone close to the victim. It is normally carried out for personal gain, most commonly of position, money, or property. Blackmail may also be considered a form of extortion. Although the two are generally synonymous, extortion is the taking of personal property by threat of future harm. Blackmail is the use of threat to prevent another from engaging in a lawful occupation and writing libelous letters or letters that provoke a breach of the peace, as well as use of intimidation for purposes of collecting an unpaid debt. In many jurisdictions, bla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HM Prison Brixton
HM Prison Brixton is a local men's prison, located in Brixton area of the London Borough of Lambeth, in inner-South London. The prison is operated by His Majesty's Prison Service. History The prison was originally built in 1820 and opened as the ''Surrey House of Correction'', Brixton Prison was intended to house 175 prisoners. However, regularly exceeding its capacity supporting over 200 prisoners, overcrowding was an early problem and with its small cells and poor living conditions contributed to its reputation as one of the worst prisons in London (worsened when Brixton became one of the first prisons to introduce penal treadmills in 1821). There is an illustration of prisoners on the 1821 treadmill used to mill corn in Surrey House of Correction. Conditions for women were especially harsh as newly arrived female inmates were made to spend four months in solitary confinement and, following their introduction into the general prison population, would be required to maintain ...

Arrest Warrant
An arrest warrant is a warrant issued by a judge or magistrate on behalf of the state, which authorizes the arrest and detention of an individual, or the search and seizure of an individual's property. Canada Arrest warrants are issued by a judge or justice of the peace under the Criminal Code. Once the warrant has been issued, section 29 of the code requires that the arresting officer must give notice to the accused of the existence of the warrant, the reason for it, and produce it if requested, if it is feasible to do so. Czech Republic Czech courts may issue an arrest warrant when it is not achievable to summon or bring in for questioning a charged person and at the same time there is a reason for detention (i.e. concern that the charged person would either flee, interfere with the proceedings or continue criminal activity, see Remand in the Czech Republic). The arrest warrant includes: * identification of the charged person * brief description of the act, for which the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Scotland Yard
Scotland Yard (officially New Scotland Yard) is the headquarters of the Metropolitan Police, the territorial police force responsible for policing Greater London's 32 boroughs, but not the City of London, the square mile that forms London's historic and primary financial centre. Its name derives from the location of the original Metropolitan Police headquarters at 4 Whitehall Place, which also had an entrance on a street called Great Scotland Yard. The Scotland Yard entrance became the public entrance, and over time "Scotland Yard" has come to be used not only as the name of the headquarters building, but also as a metonym for both the Metropolitan Police Service itself and police officers, especially detectives, who serve in it. ''The New York Times'' wrote in 1964 that, just as Wall Street gave its name to New York's financial district, Scotland Yard became the name for police activity in London. The force moved from Great Scotland Yard in 1890, to a newly completed buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ransomware (malware)
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] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.
