pharming


pharm·ing 1

P0236050 (fär′mĭng)n. The production of pharmaceuticals from genetically altered plants or animals.
[Blend of pharmaceutical and farming, gerund of farm.]
pharm v.

pharm·ing 2

P0236050 (fär′mĭng)n. A method of identity theft in which one sets up a website closely resembling a legitimate website, as of a bank, and surreptitiously redirects users trying to visit the authentic website to the fake one to trick them into revealing passwords or other personal information.
[Alteration (influenced by phish) of farm (after the server farms generally used to launch pharming attacks).]
pharm v.

pharming

(ˈfɑːmɪŋ) n (Agriculture) the practice of rearing or growing genetically-modified animals or plants in order to develop pharmaceutical products[C20: blend of pharmaceutical + farming]

pharming

(ˈfɑːmɪŋ) n (Telecommunications) the practice of redirecting computer users from legitimate websites to fraudulent ones for the purposes of extracting confidential data[C21: from farming in the sense of cultivating and harvesting; computer-hacker slang often replaces f with ph]

pharming

A method of committing fraud by redirecting the customers of a legitimate online business, such as a bank, to a website where details such as account numbers and passwords may be recorded. The website to which customers are redirected is often designed to resemble the legitimate company’s website. Unlike phishing, pharming is aimed at every person who accesses the target website.

pharming

(fär`mĭng), the use of genetically altered livestock, such as cows, goats, pigs, and chickens, to produce medically useful products. In pharming, researchers first create hybrid genes using animal DNA and the human or other gene that makes a desired substance, such as a hormone. Employing the techniques of genetic engineeringgenetic engineering,
the use of various methods to manipulate the DNA (genetic material) of cells to change hereditary traits or produce biological products. The techniques include the use of hybridomas (hybrids of rapidly multiplying cancer cells and of cells that make a

, they then introduce the hybrid genes into animal embryos, which are then reimplanted into foster mothers and carried to term, creating transgenic animals that secrete human hormones or proteins, antibiotics, or other substances in their milk, blood, semen, eggs, or the like. The material containing the secreted substance is harvested, and the substance extracted and purified. The process has yielded drugs, such as growth hormone and antithrombin; blood components, such as hemoglobin; and large quantities of certain proteins needed for research.

Still largely in the developmental stage as a manufacturing process, pharming must overcome technical and economic hurdles, and substances produced as treatments for human beings also must be tested in clinical trials. Nevertheless, it is regarded as a more efficient alternative to the technique of using genetically altered bacteria or specially cultured animal cells to produce drugs, and as the only way to produce some more complex proteins. Also being experimentally explored is the use of genetically engineered plants, specifically rubber trees, to produce pharmaceuticals in their sap and the use of transgenic animals as sources of organs for medical transplantationtransplantation, medical,
surgical procedure by which a tissue or organ is removed and replaced by a corresponding part, usually from another part of the body or from another individual.

. A necessary step toward the later was achieved in 2000 when pigs were cloned that lacked a gene that causes the human immune system to reject swine tissue.

pharming

Setting up a fraudulent website that contains copies of pages from a legitimate website in order to capture confidential information from users. By hacking into the Internet's DNS servers and changing IP addresses, users are automatically redirected to the bogus site, at least for some period of time until the DNS records can be restored. See DNS hijacking.

For example, if a bank's DNS were changed, users could be redirected to a website that looks familiar. The bogus site could collect usernames and passwords or using some pretense request additional financial information. Unlike phishing schemes that use a link in an email message to go to the phony site, pharming is more natural. Users are purposefully going to a familiar site.

Check the Address Line
The only way to avoid being suckered in is to always check the address line in the browser. Most people never do this and may not even be familiar with the valid URL of the site they go to all the time because they just click a bookmark. For example, if mybank.com were switched to mybnk.com, only an extremely observant user would notice and question this discrepancy. See phishing.

pharming

(fär′mĭng)n. The production of pharmaceuticals from genetically altered plants or animals.
pharm v.
Biotechnology (1) The production of useful molecules—e.g., proteins and pharmaceuticals from genetically engineered animals or plants
(2) The process of genetically engineering crops to protect them or consumers from disease
Informatics A portmanteau of phishing and farming. Phishing is a type of computer attack to obtain access credentials such as user names and passwords
Substance abuse A putative type of recreational drug use by teenagers in the US suburbs in which they borrow multiple prescription drugs from their home medicine cabinets, take them to parties and pool the pills in bowls for free consumption, based on the assumption that if enough of them have ‘borrowed’ enough of the right prescription drugs from the family medicine cabinets, some sort of desirable neuropharmacologic effect will ensue

pharming

use of genetically manipulated farm animals, for example sheep and goats, and crop plants in order to produce large quantities of expensive human proteins of pharmaceutical value.
