A password, sometimes called a passcode, is secret data, typically a string of characters, usually used to confirm a user's identity. Traditionally, passwords were expected to be memorized, but the large number of password-protected services that a typical individual accesses can make memorization of unique passwords for each service impractical. Using the terminology of the NIST Digital Identity Guidelines, the secret is held by a party called the claimant while the party verifying the identity of the claimant is called the verifier. When the claimant successfully demonstrates knowledge of the password to the verifier through an established authentication protocol, the verifier is able to infer the claimant's identity.
In cryptanalysis and computer security, password cracking is the process of guessing passwords protecting a computer system. A common approach is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. Another type of approach is password spraying, which is often automated and occurs slowly over time in order to remain undetected, using a list of common passwords.
Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to guess it correctly. The strength of a password is a function of length, complexity, and unpredictability.
The Internet has a long history of turbulent relations, major maliciously designed disruptions, and other conflicts. This is a list of known and documented Internet, Usenet, virtual community and World Wide Web related conflicts, and of conflicts that touch on both offline and online worlds with possibly wider reaching implications.
The 2012 LinkedIn hack refers to the computer hacking of LinkedIn on June 5, 2012. Passwords for nearly 6.5 million user accounts were stolen. Yevgeniy Nikulin was convicted of the crime and sentenced to 88 months in prison.
Hacking Team was a Milan-based information technology company that sold offensive intrusion and surveillance capabilities to governments, law enforcement agencies and corporations. Its "Remote Control Systems" enable governments and corporations to monitor the communications of internet users, decipher their encrypted files and emails, record Skype and other Voice over IP communications, and remotely activate microphones and camera on target computers. The company has been criticized for providing these capabilities to governments with poor human rights records, though HackingTeam states that they have the ability to disable their software if it is used unethically. The Italian government has restricted their licence to do business with countries outside Europe.

In July 2015, an unknown person or group calling itself "The Impact Team" announced they had stolen the user data of Ashley Madison, a commercial website billed as enabling extramarital affairs. The hacker(s) copied personal information about the site's user base and threatened to release users' names and personal identifying information if Ashley Madison would not immediately shut down. As evidence of the seriousness of the threat, the personal information of more than 2,500 users was initially released. The company initially denied that its records were insecure, but it continued to operate.
Have I Been Pwned? is a website that allows Internet users to check whether their personal data has been compromised by data breaches. The service collects and analyzes hundreds of database dumps and pastes containing information about billions of leaked accounts, and allows users to search for their own information by entering their username or email address. Users can also sign up to be notified if their email address appears in future dumps. The site has been widely touted as a valuable resource for Internet users wishing to protect their own security and privacy. Have I Been Pwned? was created by security expert Troy Hunt on 4 December 2013.
Troy Adam Hunt is an Australian web security consultant known for public education and outreach on security topics. He created and operates Have I Been Pwned?, a data breach search website that allows users to see if their personal information has been compromised. He has also authored several popular security-related courses on Pluralsight, and regularly presents keynotes and workshops on security topics. He created ASafaWeb, a tool that formerly performed automated security analysis on ASP.NET websites.
Alex Holden is the owner of Hold Security, a computer security firm. As of 2015, the firm employs 16 people.
Credential stuffing is a type of cyberattack in which the attacker collects stolen account credentials, typically consisting of lists of usernames or email addresses and the corresponding passwords, and then uses the credentials to gain unauthorized access to user accounts on other systems through large-scale automated login requests directed against a web application. Unlike credential cracking, credential stuffing attacks do not attempt to use brute force or guess any passwords – the attacker simply automates the logins for a large number of previously discovered credential pairs using standard web automation tools such as Selenium, cURL, PhantomJS or tools designed specifically for these types of attacks, such as Sentry MBA, SNIPR, STORM, Blackbullet and Openbullet.
Cloudbleed was a Cloudflare buffer overflow disclosed by Project Zero on February 17, 2017. Cloudflare's code disclosed the contents of memory that contained the private information of other customers, such as HTTP cookies, authentication tokens, HTTP POST bodies, and other sensitive data. As a result, data from Cloudflare customers was leaked to all other Cloudflare customers that had access to server memory. This occurred, according to numbers provided by Cloudflare at the time, more than 18,000,000 times before the problem was corrected. Some of the leaked data was cached by search engines.
Collection #1 is a set of email addresses and passwords that appeared on the dark web around January 2019. The database contains over 773 million unique email addresses and 21 million unique passwords, resulting in more than 2.7 billion email/password pairs. The list, reviewed by computer security experts, contains exposed addresses and passwords from over 2000 previous data breaches as well as an estimated 140 million new email addresses and 10 million new passwords from previously unknown sources, and collectively makes it the largest data breach on the Internet.
Data breach incidences in India were the second highest globally in 2018, according to a report by digital security firm Gemalto. With over 690 million internet subscribers and growing, India has increasingly seen a rise in data breaches both in the private and public sector. This is a list of some of the biggest data breaches in the country.
ShinyHunters is a black-hat criminal hacker group that is believed to have formed in 2020 and is said to have been involved in numerous data breaches. The stolen information is often sold on the dark web.
The Epik data breach occurred in September and October 2021, targeting the American domain registrar and web hosting company Epik. The breach exposed a wide range of information including personal information of customers, domain history and purchase records, credit card information, internal company emails, and records from the company's WHOIS privacy service. More than 15 million unique email addresses were exposed, belonging to customers and to non-customers whose information had been scraped. The attackers responsible for the breach identified themselves as members of the hacktivist collective Anonymous. The attackers released an initial 180 gigabyte dataset on September 13, 2021, though the data appeared to have been exfiltrated in late February of the same year. A second release, this time containing bootable disk images, was made on September 29. A third release on October 4 reportedly contained more bootable disk images and documents belonging to the Texas Republican Party, a customer of Epik's.
