資安詞彙整理 e-Glossary of Cyber Terms and Hacking Lingo


原文是幾週前從「新」媒體Vice專門報導科技數位消息的版面「motherboard」:“e-Glossary of Cyber Terms and Hacking Lingo”所轉貼過來的資料。之前翻譯umbrella-app,以及目前正在作的「level-up: Resources for the global digital safety training community.」在地化,讓我遇上許多頭痛的數位安全資訊詞彙。細看這篇文章的說明,大大幫助我這段時間入門了解了一些駭客與資訊安全常會見的字眼。於是心想,故乾脆把全文轉過來,並補充上我覺得目前對應台灣語境裏翻譯還可以接受和理解的中文對照,以方便以後的查找。其實本來是想用MarkDown,如HUGO靜態網頁生成器先來編寫初稿並打算將之全部中文化,但只有先勉強在sandsotrm.io 上利用它的web app市集,建立了一個個人的etherpad雲端應用的共享編輯筆記檔案,而全部的中文化翻譯,呃因為這篇文章似乎也只是為了個人參考,所以就放在部落格上方便回來查看其指涉的意思就好。

##A
###Attribution
歸責
Attribution is the process of establishing who is behind a hack. Often, attribution is the most difficult part of responding to a major breach since experienced hackers may hide behind layers of online services that mask their true location and identity. Many incidents, such as the Sony hack, may never produce any satisfactory attribution.

##B
###Backdoor
後門
Entering a protected system using a password can be described as going through the front door. Companies may build “backdoors” into their systems, however, so that developers can bypass authentication and dive right into the program. Backdoors are usually secret, but may be exploited by hackers if they are revealed or discovered.

###Black hat
黑帽駭客
A black hat hacker is someone who hacks for personal gain and/or who engages in illicit and unsanctioned activities. As opposed to white hack hackers (see below), who traditionally hack in order to alert companies and improve services, black hat hackers may instead sell the weaknesses they discover to other hackers or use them.

###Botnet
殭屍網路
Is your computer part of a botnet? It could be, and you might not know it. Botnets, or zombie armies, are networks of computers controlled by an attacker. Having control over hundreds or thousands of computers lets bad actors perform certain types of cyberattacks, such as a DDoS (see below). Buying thousands of computers wouldn’t be economical, however, so hackers deploy malware to infect random computers that are connected to the internet. If your computer gets infected, your machine might be stealthily performing a hacker’s bidding in the background without you ever noticing.

###Brute force
蠻力
A brute force attack is arguably the least sophisticated way of breaking into a password-protected system, short of simply obtaining the password itself. A brute force attack will usually consist of an automated process of trial-and-error to guess the correct passphrase. Most modern encryption systems use different methods for slowing down brute force attacks, making it hard or impossible to try all combinations in a reasonable amount of time.

###Bug
臭蟲
You’ve probably heard of this one. A bug is a flaw or error in a software program. Some are harmless or merely annoying, but some can be exploited by hackers. That’s why many companies have started using bug bounty programs to pay anyone who spots a bug before the bad guys do.

##C
###Cracking
攻略
A general term to describe breaking into a security system, usually for nefarious purposes. According to the New Hacker’s Dictionary published by MIT Press, the words “hacking” and “hacker” (see below) in mainstream parlance have come to subsume the words “cracking” and “cracker,” and that’s misleading. Hackers are tinkerers; they’re not necessarily bad guys. Crackers are malicious. At the same time, you’ll see cracking used to refer to breaking, say, digital copyright protections—which many people feel is a just and worthy cause—and in other contexts, such as penetration testing (see below), without the negative connotation.

###Crypto
密碼學
Short for cryptography, the science of secret communication or the procedures and processes for hiding data and messages with encryption (see below).

###Chip-off
開顱??
A chip-off attack requires the hacker to physically remove memory storage chips in a device so that information can be scraped from them using specialized software. This attack has been used by law enforcement to break into PGP-protected Blackberry phones.

##D
###Dark web
暗網
The dark web is made up of sites that are not indexed by Google and are only accessible through specialty networks such as Tor (see below). Often, the dark web is used by website operators who want to remain anonymous. Everything on the dark web is on the deep web, but not everything on the deep web is on the dark web.

###DDoS
分散式阻斷服務攻擊
This type of cyberattack has become popular in recent years because it’s relatively easy to execute and its effects are obvious immediately. DDoS stands for Distributed Denial of Service Attack, which means an attacker is using a number of computers to flood the target with data or requests for data. This causes the target—usually a website—to slow down or become unavailable. Attackers may also use the simpler Denial of Service attack, which is launched from one computer.

###Deep web
深網
This term and “dark web” or “dark net” are sometimes used interchangeably, though they shouldn’t be. The deep web is the part of the internet that is not indexed by search engines. That includes password-protected pages, paywalled sites, encrypted networks, and databases—lots of boring stuff.

###DEF CON
驗客科術大會
One of the most famous hacking conferences in the US and the world, which started in 1992 and takes place every summer in Las Vegas.

###Digital Certificate
數位認證
A digital passport or stamp of approval that proves the identity of a person, website or service on the internet. In more technical terms, a digital certificate proves that someone is in possession of a certain cryptographic key that, traditionally, can’t be forged. Some of the most common digital certificates are those of websites, which ensure your connection to them is properly encrypted. These get displayed on your browser as a green padlock.

##E
###Encryption
加密
The process of scrambling data or messages making it unreadable and secret. The opposite is decryption, the decoding of the message. Both encryption and decryption are functions of cryptography. Encryption is used by individuals as well as corporations and in digital security for consumer products.

###End-to-end encryption
端對端加密
A particular type of encryption where a message or data gets scrambled or encrypted on one end, for example your computer or phone, and get decrypted on the other end, such as someone else’s computer. The data is scrambled in a way that, at least in theory, only the sender and receiver—and no one else—can read it.

###Evil maid attack
邪惡女僕攻擊
As the name probably suggests, an evil maid attack is a hack that requires physical access to a computer—the kind of access an evil maid might have while tidying his or her employer’s office, for example. By having physical access, a hacker can install software to track your use and gain a doorway even to encrypted information.

###Exploit
An exploit is a way or process to take advantage of a bug or vulnerability in a computer or application. Not all bugs lead to exploits. Think of it this way: If your door was faulty, it could be simply that it makes a weird sound when you open it, or that its lock can be picked. Both are flaws but only one can help a burglar get in. The way the criminal picks the lock would be the exploit.

##F
###Forensics
鑑識
On CSI, forensic investigations involve a series of methodical steps in order to establish what happened during a crime. When it comes to a hack, however, investigators are looking for digital fingerprints instead of physical ones. This process usually involves trying to retrieve messages or other information from a device—perhaps a phone, a desktop computer or a server—used, or abused, by a suspected criminal.

##G
###GCHQ
The UK’s equivalent of the US' National Security Agency. GCHQ, or Government Communications Headquarters, focuses on foreign intelligence, especially around terrorism threats and cybersecurity. It also investigates the digital child pornography trade. “As these adversaries work in secret, so too must GCHQ,” the organization says on its website. “We cannot reveal publicly everything that we do, but we remain fully accountable.”

##H
###Hacker
駭客
This term has become—wrongly—synonymous with someone who breaks into systems or hacks things illegally. Originally, hackers were simply tinkerers, or people who enjoyed “exploring the details of programmable systems and how to stretch their capabilities,” as the MIT New Hacker’s Dictionary puts it. Hackers can now be used to refer to both the good guys, also known as white hat hackers, who play and tinker with systems with no malicious intent (and actually often with the intent of finding flaws so they can be fixed), and cybercriminals, or “black hat” hackers, or “crackers.”

###Hacktivist
駭客行動者
A “hacktivist” is someone who uses their hacking skills for political ends. A hacktivist’s actions may be small, such as defacing the public website of a security agency or other government department, or large, such as stealing sensitive government information and distributing it to citizens. One often-cited example of a hacktivist group is Anonymous.

###Hashing
散列、雜數
Say you have a piece of text that should remain secret, like a password. You could store the text in a secret folder on your machine, but if anyone gained access to it you’d be in trouble. To keep the password a secret, you could also “hash” it with a program that executes a function resulting in garbled text representing the original information. This abstract representation is called a hash. Companies may store passwords or facial recognition data with hashes to improve their security.

###HTTPS/SSL/TLS
Stands for Hypertext Transfer Protocol, with the “S” for “Secure.” The Hypertext Transfer Protocol (HTTP) is the basic framework that controls how data is transferred across the web, while HTTPS adds a layer of encryption that protects your connection to the most important sites in your daily browsing—your bank, your email provider, and social network. HTTPS uses the protocols SSL and TLS to not only protect your connection, but also to prove the identity of the site, so that when you type https://gmail.com you can be confident you're really connecting to Google and not an imposter site.

##I
###Infosec
資訊安全
An abbreviation of “Information Security." It’s the inside baseball term for what’s more commonly known as cybersecurity, a term that irks most people who prefer infosec.

##J
###Jailbreak
越獄
Circumventing the security of a device, like an iPhone or a PlayStation, to remove a manufacturer's restrictions, generally with the goal to make it run software from non-official sources.

##K
##Keys
密鑰
Modern cryptography uses digital “keys”. In the case of PGP encryption, a public key is used to encrypt, or “lock”, messages and a secret key is used to decrypt, or “unlock”, them. In other systems, there may only be one secret key that is shared by all parties. In either case, if an attacker gains control of the key that does the unlocking, they may have a good chance at gaining access to.

##L
###Lulz
An internet-speak variation on “lol” (short for “laughing out loud”) employed regularly among the black hat hacker set, typically to justify a hack or leak done at the expense of another person or entity. Sample use: y did i leak all contracts and employee info linked to Sketchy Company X? for teh lulz

##M
###Malware
惡意軟體
Stands for “malicious software.” It simply refers to any kind of a malicious program or software, designed to damage or hack its target. Viruses, worms, Trojan horses, ransomware, spyware, adware and more are malware.

###Man-in-the-middle
中間人攻擊
A Man-in-the-Middle or MitM is a common attack where someone surreptitiously puts themselves between two parties, impersonating them. This allows the malicious attacker to intercept and potentially alter their communication. With this type of attack, one can just passively listen in, relaying messages and data between the two parties, or even alter and manipulate the data flow.

###Metadata
Metadata is simply data about data. If you were to send an email, for example, the text you type to your friend will be the content of the message, but the address you used to send it, the address you sent it to, and the time you sent it would all be metadata. This may sound innocuous, but with enough sources of metadata—for example, geolocation information from a photo posted to social media—it can be trivial to piece together someone’s identity or location.

##N
###NIST
The National Institute of Standards and Technology is an arm of the US Department of Commerce dedicated to science and metrics that support industrial innovation. The NIST is responsible for developing information security standards for use by the federal government, and therefore it’s often cited as an authority on which encryption methods are rigorous enough to use given modern threats.

###Nonce
A portmanteau of number and once, nonce literally means “a number only used once.” It’s a string of numbers generated by a system to identify a user for a one-time-use session or specific task. After that session, or a set period of time, the number isn’t used again.

##O
###OpSec
OpSec is short for operational security, and it’s all about keeping information secret, online and off. Originally a military term, OpSec is a practice and in some ways a philosophy that begins with identifying what information needs to be kept secret, and whom you’re trying to keep it a secret from. “Good” OpSec will flow from there, and may include everything from passing messages on Post-Its instead of emails to using digital encryption. In other words: Loose tweets destroy fleets.

###OTR
不留記錄
What do you do if you want to have an encrypted conversation, but it needs to happen fast? OTR, or Off-the-Record, is a protocol for encrypting instant messages end-to-end. Unlike PGP, which is generally used for email and so each conversant has one public and one private key in their possession, OTR uses a single temporary key for every conversation, which makes it more secure if an attacker hacks into your computer and gets a hold of the keys. OTR is also generally easier to use than PGP.

##P
###Password managers
密碼管理軟體
Using the same, crummy password for all of your logins—from your bank account, to Seamless, to your Tinder profile—is a bad idea. All a hacker needs to do is get access to one account to break into them all. But memorizing a unique string of characters for every platform is daunting. Enter the password manager: software that keeps track of your various passwords for you, and can even auto-generate super complicated and long passwords for you. All you need to remember is your master password to log into the manager and access all your many different logins.

###Penetration testing or pentesting
滲透測試
If you set up a security system for your home, or your office, or your factory, you’d want to be sure it was safe from attackers, right? One way to test a system’s security is to employ people—pentesters—to purposely hack it in order to identify weak points. Pentesting is related to red teaming, although it may be done in a more structured, less aggressive way.

###PGP
“Pretty Good Privacy” is a method of encrypting data, generally emails, so that anyone intercepting them will only see garbled text. PGP uses asymmetric cryptography, which means that the person sending a message uses a “public” encryption key to scramble it, and the recipient uses a secret “private” key to decode it. Despite being more than two decades old, PGP is still a formidable method of encryption, although it can be notoriously difficult to use in practice, even for experienced users.

###Phishing
釣魚
Phishing is really more of a form of social engineering than hacking or cracking. In a phishing scheme, an attacker typically reaches out to a victim in order to extract specific information that can be used in a later attack. That may mean posing as customer support from Google, Facebook, or the victim’s cell phone carrier, for example, and asking the victim to click on a malicious link—or simply asking the victim to send back information, such as a password, in an email. Attackers usually blast out phishing attempts by the thousands, but sometimes employ more targeted attacks, known as spearphishing (see below).

###Plaintext
明文,純文字
Exactly what it sounds like—text that has not been garbled with encryption. This definition would be considered plaintext. You may also hear plaintext being referred to as “cleartext,” since it refers to text that is being kept out in the open, or “in the clear.” Companies with very poor security may store user passwords in plaintext, even if the folder they’re in is encrypted, just waiting for a hacker to steal.

###Pwned
Pwned is computer nerd jargon (or “leetspeak”) for the verb “own.” In the video game world, a player that beat another player can say that he pwned him. Among hackers, the term has a similar meaning, only instead of beating someone in a game, a hacker that has gained access to another user’s computer can say that he pwned him. For example, the website “Have I Been Pwned?” will tell you if your online accounts have been compromised in the past.

##R
###RAT
遠端控制工具
RAT stands for Remote Access Tool or Remote Access Trojan. RATs are really scary when used as malware. An attacker who successfully installs a RAT on your computer can gain full control of your machine. There is also a legitimate business in RATs for people who want to access their office computer from home, and so on. The worst part about RATs? Many malicious ones are available in the internet’s underground for sale or even for free, so attackers can be pretty unskilled and still use this sophisticated tool.

###Ransomware
勒索軟體
Ransomware is a type of malware that locks your computer and won’t let you access your files. You’ll see a message that tells you how much the ransom is and where to send payment, usually requested in bitcoin, in order to get your files back. This is a good racket for hackers, which is why many consider it now an “epidemic,” as people typically are willing to pay a few hundred bucks in order to recover their machine. It’s not just individuals, either. In early 2016, the Hollywood Presbyterian Medical Center in Los Angeles paid around $17,000 after being hit by a ransomware attack.

###Rainbow table
彩虹表
A rainbow table is a complex technique that allows hackers to simplify the process of guessing what passwords hide behind a “hash” (see above).

###Red team
To ensure the security of their computer systems and to suss out any unknown vulnerabilities, companies may hire hackers who organize into a “red team” in order to run oppositional attacks against the system and attempt to completely take it over. In these cases, being hacked is a good thing because organizations may fix vulnerabilities before someone who’s not on their payroll does. Red teaming is a general concept that is employed across many sectors, including military strategy.

###Root
In most computers, “root” is the common name given to the most fundamental (and thus most powerful) level of access in the system, or is the name for the account that has those privileges. That means the “root” can install applications, delete and create files. If a hacker “gains root,” they can do whatever they want on the computer or system they compromised. This is the holy grail of hacking.

###Rootkit
A rootkit is a particular type of malware that lives deep in your system and is activated each time you boot it up, even before your operating system starts. This makes rootkits hard to detect, persistent, and able to capture practically all data on the infected computer.

##S
###Salting
When protecting passwords or text, “hashing” (see above) is a fundamental process that turns the plaintext into garbled text. To make hashing even more effective, companies or individuals can add an extra series of random bytes, known as a “salt,” to the password before the hashing process. This adds an extra layer of protection.

###Script kiddies
This is a derisive term for someone who has a little bit of computer savvy and who’s only able to use off-the-shelf software to do things like knock websites offline or sniff passwords over an unprotected Wi-Fi access point. This is basically a term to discredit someone who claims to be a skilled hacker.

###Shodan
It’s been called “hacker’s Google,” and a “terrifying” search engine. Think of it as a Google, but for connected devices rather than websites. Using Shodan you can find unprotected webcams, baby monitors, printers, medical devices, gas pumps, and even wind turbines. While that’s sounds terrifying, Shodan’s value is precisely that it helps researchers find these devices and alert their owners so they can secure them.

###Signature
數位簽章
Another function of PGP, besides encrypting messages, is the ability to “sign” messages with your secret encryption key. Since this key is only known to one person and is stored on their own computer and nowhere else, cryptographic signatures are supposed to verify that the person who you think you’re talking to actually is that person. This is a good way to prove that you really are who you claim to be on the internet.

###Side channel attack
旁路攻擊
Your computer’s hardware is always emitting a steady stream of barely-perceptible electrical signals. A side-channel attack seeks to identify patterns in these signals in order to find out what kind of computations the machine is doing. For example, a hacker “listening in” to your hard drive whirring away while generating a secret encryption key may be able to reconstruct that key, effectively stealing it, without your knowledge.

###Sniffing
封包竊聽
Sniffing is a way of intercepting data sent over a network without being detected, using special sniffer software. Once the data is collected, a hacker can sift through it to get useful information, like passwords. It’s considered a particularly dangerous hack because it’s hard to detect and can be performed from inside or outside a network.

###Social engineering
社交工程
Not all hacks are carried out by staring at a Matrix-like screen of green text. Sometimes, gaining entry to a secure system is as easy as placing a phone call or sending an email and pretending to be somebody else—namely, somebody who regularly has access to said system but forgot their password that day. Phishing (see above) attacks include aspects of social engineering, because they involve convincing somebody of an email sender’s legitimacy before anything else.

###Spearphishing
魚叉式網路釣魚
Phishing and spearphishing are often used interchangeably, but the latter is a more tailored, targeted form of phishing (see above), where hackers try to trick victims into clicking on malicious links or attachments pretending to be a close acquaintance, rather than a more generic sender, such as a social network or corporation. When done well, spearphishing can be extremely effective and powerful. As a noted security expert says, “give a man a 0day and he'll have access for a day, teach a man to phish and he'll have access for life.”

###Spoofing
欺騙
Hackers can trick people into falling for a phishing attack (see above) by forging their email address, for example, making it look like the address of someone the target knows. That’s spoofing. It can also be used in telephone scams, or to create a fake website address.

###Spyware
間諜軟體
A specific type of malware of malicious software designed to spy, monitor, and potentially steal data from the target.

###State actor
State actors are hackers or groups of hackers who are backed by a government, which may be the US, Russia, or China. These hackers are often the most formidable, since they have the virtually unlimited legal and financial resources of a nation-state to back them up. Think, for example, of the NSA. Sometimes, however, state actors can also be a group of hackers who receive tacit (or at least hidden from the public) support from their governments, such as the Syrian Electronic Army.

##T
###Threat model
威脅模型
Imagine a game of chess. It’s your turn and you’re thinking about all the possible moves your opponent could make, as many turns ahead as you can. Have you left your queen unprotected? Is your king being worked into a corner checkmate? That kind of thinking is what security researchers do when designing a threat model. It’s a catch-all term used to describe the capabilities of the enemy you want to guard against, and your own vulnerabilities. Are you an activist attempting to guard against a state-sponsored hacking team? Your threat model better be pretty robust. Just shoring up the network at your log cabin in the middle of nowhere? Maybe not as much cause to worry.

##Token
動態簡訊密碼器
A small physical device that allows its owner to log in or authenticate into a service. Tokens serve as an extra layer of security on top of a password, for example. The idea is that even if the password or key gets stolen, the hacker would need the actual physical token to abuse it.

###Tor
Tor is short for The Onion Router. Originally developed by the United States Naval Research Laboratory, it’s now used by bad guys (hackers, pedophiles) and good guys (activists, journalists) to anonymize their activities online. The basic idea is that there is a network of computers around the world—some operated by universities, some by individuals, some by the government—that will route your traffic in byzantine ways in order to disguise your true location. The Tor network is this collection of volunteer-run computers. The Tor Project is the nonprofit that maintains the Tor software. The Tor browser is the free piece of software that lets you use Tor. Tor hidden services are websites that can only be accessed through Tor.

###Tails
Tails stands for The Amnesic Incognito Live System. If you’re really, really serious about digital security, this is the operating system endorsed by Edward Snowden. Tails is an amnesic system, which means your computer remembers nothing; it’s like a fresh machine every time you boot up. The software is free and open source. While it’s well-regarded, security flaws have been found.

##V
###Verification (dump)
核實
The process by which reporters and security researchers go through hacked data and make sure it’s legitimate. This process is important to make sure the data is authentic, and the claims of anonymous hackers are true, and not just an attempt to get some notoriety or make some money scamming people on the dark web.

###VPN
VPN stands for Virtual Private Network. VPNs use encryption to create a private and secure channel to connect to the internet when you’re on a network you don’t trust (say a Starbucks, or an Airbnb WiFi). Think of a VPN as a tunnel from you to your destination, dug under the regular internet. VPNs allow employees to connect to their employer’s network remotely, and also help regular people protect their connection. VPNs also allow users to bounce off servers in other parts of the world, allowing them to look like they’re connecting from there. This gives them the chance to circumvent censorship, such as China’s Great Firewall, or view Netflix’s US offerings while in Canada. There are endless VPNs, making it almost impossible to decide which ones are the best.

###Virus
病毒
A computer virus is a type of malware that typically is embedded and hidden in a program or file. Unlike a worm (see below), it needs human action to spread (such as a human forwarding a virus-infected attachment, or downloading a malicious program.) Viruses can infect computers and steal data, delete data, encrypt it or mess with it in just about any other way.

###Vuln
漏洞
Abbreviation for “vulnerability.” Another way to refer to bugs or software flaws that can be exploited by hackers.

##W
###Warez
Pronounced like the contraction for “where is” (where’s), warez refers to pirated software that’s typically distributed via technologies like BitTorrent and Usenet. Warez is sometimes laden with malware, taking advantage of people’s desire for free software.

###White hat
白帽駭客
A white hat hacker is someone who hacks with the goal of fixing and protecting systems. As opposed to black hat hackers (see above), instead of taking advantage of their hacks or the bugs they find to make money illegally, they alert the companies and even help them fix the problem.

###Worm
蠕蟲
A specific type of malware that propagates and replicates itself automatically, spreading from computer to computer. The internet’s history is littered with worms, from the Morris worm, the first of its kind, and the famous Samy worm, which infected more than a million people on MySpace.

##Z
###Zero-day
零日攻擊
A zero-day or “0day” is a bug that’s unknown to the software vendor, or at least it’s not patched yet. The name comes from the notion that there have been zero days between the discovery of the bug or flaw and the first attack taking advantage of it. Zero-days are the most prized bugs and exploits for hackers because a fix has yet to be deployed for them, so they’re almost guaranteed to work.
