The Internet service company Yahoo! was subjected to the largest data breach on record.[1] Two major data breaches of user account data to hackers were revealed during the second half of 2016. The first announced breach, reported in September 2016, had occurred sometime in late 2014, and affected over 500 million Yahoo! user accounts.[2] A separate data breach, occurring earlier around August 2013, was reported in December 2016. Initially believed to have affected over 1 billion user accounts,[3] Yahoo! later affirmed in October 2017 that all 3 billion of its user accounts were impacted.[4] Both breaches are considered the largest discovered in the history of the Internet. Specific details of material taken include names, email addresses, telephone numbers, encrypted or unencrypted security questions and answers, dates of birth, and hashed passwords.[5] Further, Yahoo! reported that the late 2014 breach likely used manufactured web cookies to falsify login credentials, allowing hackers to gain access to any account without a password.[6][7][8][9]

Around July 2016, account names and passwords for about 200 million Yahoo! accounts were presented for sale on the darknet market site, "TheRealDeal".[11][12] The seller, known as "Peace_of_Mind" or simply "Peace", stated in confidential interviews with Vice and Wired, that he had the data for some time and had been selling it privately since about late 2015. Peace has previously been connected to sales of similar private information data from other hacks including that from the 2012 LinkedIn hack.[13][14] Peace stated the data likely dates back to 2012, and security experts believed it may have been parts of other data hacks at that time; while some of the sample accounts were still active, they lacked necessary information to fully login properly, reflecting their age.[13] Experts believe that Peace is only a broker of the information that hackers obtain and sell through him.[15] Yahoo! stated they were aware of the data and were evaluating it, cautioning users about the situation but did not reset account passwords at that time.[13]
The first reported data breach in 2016 had taken place sometime in late 2014, according to Yahoo![16][17][18] The hackers had obtained data from over 500 million user accounts, including account names, email addresses, telephone numbers, dates of birth, hashed passwords, and in some cases, encrypted or unencrypted security questions and answers.[19][20] Security experts noted that the majority of Yahoo!'s passwords used the bcrypt hashing algorithm, which is considered difficult to crack, with the rest using the older MD5 algorithm, which can be broken rather quickly.[21]
Yahoo! reported the breach to the public on September 22, 2016. Yahoo! believes the breach was committed by "state-sponsored" hackers,[28] but did not name any country.[5] Yahoo! affirmed the hacker was no longer in their systems and that the company was fully cooperating with law enforcement.[29] The Federal Bureau of Investigation (FBI) confirmed that it was investigating the affair.[5]
InfoArmor issued a report that challenged Yahoo's claim that a nation-state orchestrated the heist after reviewing a small sample of compromised accounts.[47] InfoArmor had been able to obtain the list of affected accounts for analysis. InfoArmor determined that the breach was likely the work of an Eastern European criminal gang that later sold the entire hacked database to at least three clients, including one state-sponsored group. According to InfoArmor, by early 2015, the group no longer offered to sell the full database, but sought "to extract something from the dump for significant amounts of money." The report noted that it was difficult to determine who the ultimate mastermind of a hack might be, as criminal hackers sometimes provide information to government intelligence agencies or offer their services for hire. Komarov said the hackers may be related to Group E, who have had a track record of selling stolen personal data on the dark web, primarily to underground spammers, and were previously linked to breaches at LinkedIn, Tumblr, and MySpace.[48] InfoArmor had linked Group E as the source of the data that were offered by Peace, and believed that Group E was brokering the data to dark web sellers.[15] While InfoArmor did not believe a state-sponsored agency committed the breach, they warned of implications on foreign intelligences, as the breaches "opens the door to significant opportunities for cyber-espionage and targeted attacks," and may be the key in several targeted attacks against U.S. government personnel, which resulted after the disclosed contacts of the affected high-level officials of intelligence community in October 2015.[47][49]
On March 15, 2017, the FBI officially charged the 2014 breach to four men, including two that work for Russia's Federal Security Service (FSB). In its statement, the FBI said "The criminal conduct at issue, carried out and otherwise facilitated by officers from an FSB unit that serves as the FBI's point of contact in Moscow on cybercrime matters, is beyond the pale."[52] The four men accused include Alexsey Belan, a hacker on the FBI Ten Most Wanted Fugitives list, FSB agents Dmitry Dokuchaev and Igor Sushchin who the FBI accused of paying Belan and other hackers to conduct the hack, and Canadian hacker Karim Baratov who the FBI claimed was paid by Dokuchaev and Sushchin to use data obtained by the Yahoo! breaches to breach into about 80 non-Yahoo! accounts of specific targets.[53] Baratov, the only man currently arrested, was extradited to the United States, though had claimed not guilty to the charges in August 2017.[53] However, he later pled guilty, admitting to hacking into at least 80 email accounts on behalf of Russian contacts. He was charged with nine counts of hacking, and in May 2018 sentenced to 5 years in prison and ordered to pay US$2.25 million and restitution to his victims.[54]
Yahoo!'s delay in discovering and reporting these breaches, as well as implementing improved security features, has become a point of criticism.[55] Yahoo! has been taken to task for having a seemingly lax attitude towards security: the company reportedly does not implement new security features as fast as other Internet companies, and after Yahoo! was identified by Edward Snowden as a frequent target for state-sponsored hackers in 2013, it took the company a full year before hiring a dedicated chief information security officer, Alex Stamos. While Stamos' hiring was praised by technology experts as showing Yahoo!'s commitment towards better security, Yahoo! CEO Marissa Mayer had reportedly denied Stamos and his security team sufficient funds to implement recommended stronger security measures, and he departed the company by 2015. Experts have pointed out that Yahoo!, only until the most recent breaches, had not forced affected users to change their passwords, a move that Mayer and her team believed would drive users away from the service.[56] Some experts stated that implementing stronger security measures does take monetary resources, and Yahoo!'s financial situation has not allowed the company to invest in cybersecurity.[55]
The FSB officer defendants, Dmitry Dokuchaev and Igor Sushchin, protected, directed, facilitated and paid criminal hackers to collect information through computer intrusions in the U.S. and elsewhere. In the present case, they worked with co-defendants Alexsey Belan and Karim Baratov to obtain access to the email accounts of thousands of individuals.

As originally announced, hackers in the 2013 breach stole account information such as names, email addresses, phone numbers, birth dates as well as hashed passwords and security questions and answers. Yahoo, now known as Oath, says in late 2016 it forced password changes for all accounts that haven't done so since 2013 and invalidated old security questions and answers.
This is a more complicated email hacking technique compared to Keylogging. Phishing entails the use of spoofed webpages that are designed to be identical to those of legitimate websites. When carrying out this social engineering hacking technique, phishers typically create fake login pages that resemble Gmail, Yahoo, or other email service providers. Once you attempt to enter your login credentials on the fake login pages, hackers will be able to steal the information right away.
Similarly, phishers can send an email that resembles what Google or Yahoo typically send. Often, such emails contain links to fake login pages, requesting you to update your email account information or change the password. An online persona of someone you know can also be created and used to hoodwink you into providing your email login credentials. To successfully execute a phishing attack, one needs considerable hacking knowledge with prior experience in HTML, scripting languages such as PHP/JSP, and CSS.
Yahoo is widely used for personal and business purposes worldwide. Yahoo allows people to instantly share crucial documents, photographs, files, etc. However, we cant say yahoo is fully safe and secure.
That means everyone you know or have ever emailed could suddenly be the target of a phishing scam or other types of social engineering attacks. And because the hacker is using your email, your family, friends, and other contacts are more likely to open them and even click links.
Access to your email can often be enough for hackers to commit all different types of identity theft. Remember, your email is like your online ID. Scammers can use it to sign you up for almost anything. Or, they can fake your online persona for other reasons.
Hacking someone's Yahoo email password is not something you wake up and do without a good reason. So, before we get our hands dirty and learn about the best way on how to hack into yahoo email without password, here are some of the reasons as to why you would consider hacking someone's Yahoo email password. 2ff7e9595c
