Ransomware (malware)
Ransomware is a type of malware that Encryption, encrypts the victim's personal data until a ransom is paid. Difficult-to-trace Digital currency, digital currencies such as paysafecard or Bitcoin and other cryptocurrency, cryptocurrencies are commonly used for the ransoms, making tracing and prosecuting the perpetrators difficult. Sometimes the original files can be retrieved without paying the ransom due to implementation mistakes, leaked cryptographic keys or a complete lack of encryption in the ransomware. Ransomware attacks are typically carried out using a Trojan horse (computing), 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 automatically between computers without user interaction. Starting as early as 1989 with the first documented ransomware known as the AIDS (Trojan horse), AIDS trojan, the use of ransomware scams grew inter ...

Internet Crime Complaint Center
The Internet Crime Complaint Center (IC3) is a division of the Federal Bureau of Investigation (FBI) concerning suspected Internet-facilitated criminal activity. The IC3 gives victims a convenient and easy-to-use reporting mechanism that alerts authorities of suspected criminal or civil violations on the Internet. The IC3 develops leads and notifies Law enforcement agency, law enforcement agencies at the federal, state, local and international level. Information sent to the IC3 is analyzed and disseminated for investigative and intelligence purposes to law enforcement and for public awareness. History The IC3 was founded in 2000 as the Internet Fraud Complaint Center (IFCC), and was tasked with gathering data on crimes committed online such as fraud, scams, and thefts. Other crimes tracked by the center included intellectual property rights matters, computer intrusions, economic espionage, Extortion, online extortion, international money laundering, identity theft, and other I ...

Piracy (media)
Copyright infringement (at times referred to as piracy) is the use of works protected by copyright without permission for a usage where such permission is required, thereby infringing certain exclusive rights granted to the copyright holder, such as the right to reproduce, distribute, display or perform the protected work, or to produce derivative works. The copyright holder is usually the work's creator, or a publisher or other business to whom copyright has been assigned. Copyright holders routinely invoke legal and technological measures to prevent and penalize copyright infringement. Copyright infringement disputes are usually resolved through direct negotiation, a notice and take down process, or litigation in civil court. Egregious or large-scale commercial infringement, especially when it involves counterfeiting, or the fraudulent imitation of a product or brand, is sometimes prosecuted via the criminal justice system. Shifting public expectations, advances in digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pornography
Pornography (colloquially called porn or porno) is Sexual suggestiveness, sexually suggestive material, such as a picture, video, text, or audio, intended for sexual arousal. Made for consumption by adults, pornographic depictions have evolved from cave paintings, some forty millennia ago, to modern-day Virtual reality pornography, virtual reality presentations. A general distinction of adults-only sexual content is made, classifying it as pornography or erotica. The oldest Artifact (archaeology), artifacts considered pornographic were discovered in Germany in 2008 and are dated to be at least 35,000 years old. Human enchantment with sexual imagery representations has been a constant throughout history of erotic depictions, history. However, the reception of such imagery varied according to the historical, cultural, and national contexts. The Indian Sanskrit text ''Kama Sutra'' (3rd century CE) contained prose, poetry, and illustrations regarding sexual behavior, and the book ...

Law Enforcement Agency
A law enforcement agency (LEA) is any government agency responsible for law enforcement within a specific jurisdiction through the employment and deployment of law enforcement officers and their resources. The most common type of law enforcement agency is the police, but various other forms exist as well, including agencies that focus on specific legal violation, or are organized and overseen by certain Authority, authorities. They typically have various Law enforcement agency powers, powers and Rights, legal rights to allow them to perform their duties, such as the power of arrest and the use of force. Jurisdiction LEAs which have their ability to apply their powers restricted in some way are said to operate within a jurisdiction. Jurisdictions are traditionally restricted to a geographic area and territory. LEA might be able to apply its powers within a Sovereign state, state (e.g. the National Police (France), National Police for the entirety of France), within an administr ...

Payload (computing)
In computing and telecommunications, the payload is the part of transmitted data that is the actual intended message. Headers and metadata are sent only to enable payload delivery and are considered overhead. In the context of a computer virus or worm, the payload is the portion of the malware which performs malicious action. The term is borrowed from transportation, where '' payload'' refers to the part of the load that ''pays'' for transportation. Networking In computer networking, the data to be transmitted is the payload. It is almost always encapsulated in some type of frame format, composed of framing bits and a frame check sequence. Examples are Ethernet frames, Point-to-Point Protocol (PPP) frames, Fibre Channel frames, and V.42 modem frames. Programming In computer programming, the most common usage of the term is in the context of message protocols, to differentiate the protocol overhead from the actual data. For example, a JSON web service response might ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phishing
Phishing is a form of social engineering and a scam where attackers deceive people into revealing sensitive information or installing malware such as viruses, worms, adware, or ransomware. Phishing attacks have become increasingly sophisticated and often transparently mirror the site being targeted, allowing the attacker to observe everything while the victim navigates the site, and transverses any additional security boundaries with the victim. As of 2020, it is the most common type of cybercrime, with the Federal Bureau of Investigation's Internet Crime Complaint Center reporting more incidents of phishing than any other type of cybercrime. The term "phishing" was first recorded in 1995 in the cracking toolkit AOHell, but may have been used earlier in the hacker magazine '' 2600''. It is a variation of ''fishing'' and refers to the use of lures to "fish" for sensitive information. Measures to prevent or reduce the impact of phishing attacks include legislation, user educa ...

Zeroisation
In cryptography, zeroisation (also spelled zeroization) is the practice of erasing sensitive parameters (electronically stored data, cryptographic keys, and critical security parameters) from a cryptographic module to prevent their disclosure if the equipment is captured. This is generally accomplished by altering or deleting the contents to prevent recovery of the data. Mechanical When encryption was performed by mechanical devices, this would often mean changing all the machine's settings to some fixed, meaningless value, such as zero. On machines with letter settings rather than numerals, the letter 'O' was often used instead. Some machines had a button or lever for performing this process in a single step. Zeroisation would typically be performed at the end of an encryption session to prevent accidental disclosure of the keys, or immediately when there was a risk of capture by an adversary. Software In modern software based cryptographic modules, zeroisation is made consider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Symmetric-key Algorithm
Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys. The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information link. The requirement that both parties have access to the secret key is one of the main drawbacks of symmetric-key encryption, in comparison to public-key encryption (also known as asymmetric-key encryption). However, symmetric-key encryption algorithms are usually better for bulk encryption. With exception of the one-time pad they have a smaller key size, which means less storage space and faster transmission. Due to this, asymmetric-key encryption is often used to exchange the secret key for symmetric-key encryption. Types Symmetric-key encryption can use either stream ciphers or block ci ...
