Dictionary attacks are similar to brute force methods but involve hackers running automated scripts that take lists of known usernames and passwords and run them against a login system sequentially to gain access to a service. It means every username would have to be checked against every possible password before the next username could be attempted against every possible password.
For example, if a hacker is aware that a password begins with a number, they will be able to tailor the mask to only try those types of passwords. Password length, the arrangement of characters, whether special characters are included, or how many times a single character is repeated are just some of the criteria that can be used to configure the mask.
Offline hacking usually involves the process of decrypting passwords by using a list of hashes likely taken from a recent data breach. Without the threat of detection or password form restrictions, hackers are able to take their time.
Somewhat self-explanatory, shoulder surfing simply sees hackers peering over the shoulder of a potential target, looking to visually track keystrokes when entering passwords. This could take place in any public space like a coffee shop, or even on public transport such as a flight. An employee may be accessing in-flight internet to complete a task before landing and the hacker could be sitting nearby, watching for an opportunity to note down a password to an email account, for example.
If all else fails, a hacker can always try and guess your password. While there are many password managers available that create strings that are impossible to guess, many users still rely on memorable phrases. These are often based on hobbies, pets, or family, much of which is often contained in the very profile pages that the password is trying to protect.
No matter the decillion count, if someone tells someone else their password the security has been compromised. Does the use of one password for multiple accounts example: yahoo, facebook, hotmail, financial, gmail, etc. decrease its strength? If someones gmail account is hacked, does the person/ program that hacked it search the world for that password or is it the other way around in that the guessed password is revealed in on list of accounts? Thank you ahead of time. See now I don't even want to put anything that related to me fearing that the hack monster will nail me. AHHH!
In May 2016, a search engine for hacked data and a hacker obtained over 400 million records from MySpace. Both parties claimed that they had obtained the data from a past, unreported data security incident. The leaked information contained emails, passwords, usernames, and second passwords. The hacker tried to sell the information for $2,800 or 6 Bitcoin on the dark web.
Summary: The hacker who stole 617 million records from the 16 sites earlier in this list stole another 127 million from 8 more websites. They pulled data from websites that included Houzz, Ge.tt, Ixigo, YouNow, Roll20, Coinmama, Stronghold Kingdoms, and PetFlow. After gathering all the information, the hacker put up the hacked data for $14,500 in Bitcoin. Most of the stolen information consisted of email addresses, names, scrambled passwords, and other account and login data.
Summary: A hacker accessed 77 million Sony PSN and Qriocity user accounts. These users were also unable to go online for 23 days due to the hack. Although Sony encrypted all of the credit card information on its systems and there was no evidence that credit card data had been stolen, the hacker may have been able to access credit card numbers and CVV numbers. In addition, other personal data, such as names, email addresses, dates of birth, account passwords, and addresses, were also compromised. 2b1af7f3a8
