Covert information leakage attacks carried out by cryptoviruses, cryptotrojans, and cryptoworms that, by definition, contain and use the public key of the attacker is a major theme in cryptovirology. In "deniable password snatching," a cryptovirus installs a cryptotrojan that asymmetrically encrypts host data and covertly broadcasts it.
CryptoLocker typically propagated as an attachment to a seemingly innocuous email message, which appears to have been sent by a legitimate company. [5] A ZIP file attached to an email message contains an executable file with the filename and the icon disguised as a PDF file, taking advantage of Windows' default behaviour of hiding the extension from file names to disguise the real .EXE extension.
Lymphocryptovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Gammaherpesvirinae.This genus includes the human-infecting Human gammaherpesvirus 4 (Epstein–Barr virus), as well as viruses that infect both Old World monkeys and New World monkeys.

A cryptovirus is a virus that contains and uses a public key and randomly generated symmetric cipher initialization vector (IV) and session key (SK). In the cryptoviral extortion attack, the virus hybrid encrypts plaintext data on the victim's machine using the randomly generated IV and SK.

A cryptovirus, cryptotrojan, or cryptoworm hybrid encrypts the victim's files using the public key of the author and the victim must pay (with money, information, etc.) to obtain the needed session key. This is one of many attacks, both overt and covert, in the field known as cryptovirology. [8]
Young and Yung critiqued the failed AIDS Information Trojan that relied on symmetric cryptography alone, the fatal flaw being that the decryption key could be extracted from the Trojan, and implemented an experimental proof-of-concept cryptovirus on a Macintosh SE/30 that used RSA and the Tiny Encryption Algorithm (TEA) to hybrid encrypt the ...
Cryptosporidiosis, sometimes informally called crypto, [1] is a parasitic disease caused by Cryptosporidium, a genus of protozoan parasites in the phylum Apicomplexa.It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune ...
