Dyachenko notified the relevant person about the incident, and Internetprovider on December 9 the base was data protected.

The database contained 2.7 billion email addresses and more than 1 billion unencrypted passwords to them. As the database analysis showed, most of the data is a leak put up for sale by a cybercriminal under the pseudonym DoubleFlag in early 2017. The leak, called the Big Asian Leak, included user data from a number of Chinese internet companies, including NetEase, Tencent, Sohu and Sina.

The 1.5 TB leak mainly contains the email addresses of Chinese users (qq.com, 139.com, 126.com, gfan.com and game.sohu.com). Most user names are dialed numbers or telephone numbers. As explained by Comparitech experts, such usernames are characteristic of residents China who have difficulties with the characters of the Latin alphabet.

Who owned the open database is unknown. In theory, it could be collected at the first stage of an attack with credential stuffing or a spam campaign^[3].

Commercial secrets of Ford, Tesla and Toyota hit the Web

Security researchers at UpGuard reported in July 2018 the leak of confidential documents from more than 100 companies, including General Motors, Fiat Chrysler, Ford, Tesla, Toyota, ThyssenKrupp and Volkswagen. The data was publicly available on a server owned by Level One Robotics^[4][5].

The reason for the leak was the general rsync file transfer protocol used to back up large datasets.

No restrictions were set on the rsync server, security researchers said. Thus, any client connected to the rsync port had access to the data download. Rsync servers must be restricted to IP addresses so that only certain clients can connect to them. In addition, user access to rsync must be configured so that clients are authenticated before accessing the data, experts noted.

In total, experts found 157 gigabytes of data containing assembly line diagrams, plans and diagrams of factory floors, documentation, forms of requests for identification forms, etc.

In addition, the personal data of some employees were disclosed, including copies of driver's licenses and passports, as well as important business documents including invoices, contracts and bank account details.

Data from 200 million Japanese are sold on the darknet

A hacker, presumably of Chinese origin, sells data from 200 million residents on a cybercriminal forum. Japan The data was probably stolen from 50 hacked small sites and collected into one archive in December 2017, Bleeping Computer reported in May 2018.^[6]

After analyzing the data samples, FireEye researchers concluded that they belong to users of the websites of companies specializing in trade, food and drink, entertainment and transportation. Experts are confident in the authenticity of the archive, since the data of the same users are found in different leaks.

The presence of old and new data in the archive indicates that they were stolen between March 2013 and June 2016. The nature of the data varies depending on the sites, however, as a rule, they are e-mail and home addresses, real names, dates of birth and phone numbers.

The cost of the archive is 1,000 Japanese yen (about $150.96). Some alleged buyers complained on the forum that they paid for the purchase, but never received the files. The reliability of such complaints is very doubtful, since they could be published by hacker competitors interested in selling their own archives. Nevertheless, given that the current population of Japan is about 127 million people, it is not clear where the data in the archive comes from another 73 million.

Biggest retail data breach

In early April 2018, it became known about the largest data breach in retail in history.

Giant interactive base found with leaks

In early December 2017, analysts at 4iQ discovered a huge interactive database on the darknet, combining 252 different data leaks.

The database with a total volume of more than 41 GB is regularly updated and offers users more than 1.4 billion credentials in plain text format. Who compiled this dump is unknown, the author indicated only Bitcoin and Dogecoin wallets for donations.

The researchers 4iQ indicated that all passwords are presented in the database in clear text and, according to testing conducted by experts, many of them are valid. Moreover, about 14% of passwords found in the database were not published anywhere. The date of the database update is November 29, 2017, it is available for searching, importing leaks and other functions.

This database includes a summary list with Exploit [.] in, another summary database of Anti Public credentials, 133 additional major leaks, for example , LinkedIn, Netflix, Last.FM and YouPorn.

4iQ experts noted 385 million new login/password pairs and 318 million new compromised users. Below is a table of the most common passwords compiled by the researchers^[7].

According to Reuters, citing three knowledgeable informants, in November 2016, Uber transferred $100,000 to a 20-year-old hacker from Florida (USA) for not disclosing personal information of users. The payment was made through the bug bounty system, which is usually used for small user incentives that indicate the vulnerabilities of the service.

Heathrow security data found in flash drive found

As it became known in October 2017, an unknown person found on flash drive the ground, which revealed detailed information about the security systems of the largest Great Britain airport. Heathrow^[8] to Daily Mail journalists, who were transferred a "flash drive," it contained 76 files with a total volume of 2.5 gigabytes, containing information about the security measures taken to protect Queen Elizabeth II and the country's top politicians when using the airport, as well as anti-terrorist measures.

Dow Jones mistakenly released data of 2.2 million of its customers

In July 2017, one of the world's leading financial information agencies Dow Jones & Company, due to an error in the settings of the cloud storage database, published in the public domain the data of several million of its customers, including names, internal identifiers, addresses, payment details and bank card data.

According to Dow Jones representatives, the repository contains information about 2.2 million customers, but independent experts believe that the number of victims may reach 4 million.

For its part, Dow Jones has confirmed the data leak, but they do not plan to notify customers about it. Dow Jones analysts argue this decision by the fact that the data in the public domain is not confidential, since it does not contain passwords in clear text.

Personal data of 14 million Verizon customers were in the public domain

In July 2017, it became known about a major leak of personal data of 14 million customers of the telecommunications corporation Verizon. According to UpGuard, an information security company, more than 20GB of information has been leaked online, including names, addresses, customer account details and even PINs to their Verizon user accounts.^[9]

UpGuard experts in early June 2017 discovered a public server in the Amazon S3 cloud, where information about Verizon clients was stored. The owner of the server is a partner of Verizon, the Israeli company NICE Systems. The folders named by month contained data from January to June 2017 - in ZIP archives with unencrypted text files totaling about 23 GB. There were also audio recordings of calls to the Verizon support line.

In addition, the same server stored data belonging to another company - the French telecom operator Orange. However, client information was not detected, only internal files.

As it turned out, open access was the result of a "human error" - NICE administrators incorrectly configured the server.

The researchers promptly informed Verizon and NICE about the leak, however, access to the data was not closed until nine days later.

Since the server was available via a direct link, the likelihood that someone could get to the data earlier than UpGuard is small, but still remains.

Meanwhile, Verizon representatives claim that the investigation did not reveal unauthorized access to this data, but do not explain why they draw such a conclusion.

Hackers published 25 thousand photos of patients of the Lithuanian plastic surgery clinic

A giant database called the "mother of all leaks" was discovered on the Web

Information security experts discovered^[10] in May 2017 in the public domain a database with 560 million leaked passwords, which MacKeeper researchers have already dubbed the "mother of all leaks." As a check using the Have I Been Pwned platform showed, the database contains over 243 million unique email addresses leaked as a result of certain hacks.

According to researchers from MacKeeper, the database is another giant array of credentials collected from various sources. It is not surprising that compromised passwords have been circulating on the Web for some time, but the existence of a ready-made database that allows anyone to take possession of them raises concerns.

In total, the researchers found 313 large databases larger than 1 GB containing terabytes of information. Databases are located in cloud storage in the United States, Canada and Australia, but it is quite difficult to determine their true owners.

The size of the detected database is 75 GB. It contains structured data in a readable json format, leaked as a result of at least ten well-known hacks, including LinkedIn, Dropbox, MySpace, Neopets, RiverCityMedia, Tumblr, MySPace and Lastfm^[11]

US retailer Neiman Marcus fine

Savings on electronic security systems can lead to significant financial and reputational losses. The American retailer Neiman Marcus is forced to pay $1.6 million for not taking proper measures to protect against hacking and untimely informing buyers about the leakage of payment card data.

Presumably 350 thousand data of Neiman Marcus customers were leaked back in 2013, and only on March 17, 2017 a final decision was made regarding compensation for the victims.

An insufficiently reliable data protection system and untimely informing customers became the reason for a class action lawsuit. As a result of the proceedings, the court ruled that Neiman Marcus is obliged to pay $1.6 million, as well as continue to carry out measures to strengthen cyber defense. The retailer has already installed new, safer readers at the checkout that make it harder to steal data, and provided a system to protect against malicious software. A cyber attack on an electronic system at the cash desks of the Neiman Marcus store chain caused the credit and debit card data of about 350 thousand of the retailer's customers to become available to cybercriminals. Neiman Marcus customers who made purchases from July 16, 2013 to January 10, 2014 were attacked. Worst of all, the violation was not immediately identified, but only after a few months. And even after it was discovered, the retailer did not immediately inform customers of the sensitive data breach^[12].

25 million Gmail logins with passwords put up for sale

Millions of logins and passwords for Gmail and Yahoo mailboxes were put up for auction on the darknet in March. The seller is a user with the nickname SunTzu583, previously seen in the wholesale of hacked Gmail and PlayStation accounts. Now he has put up for auction record-breaking data arrays, and most of them are precisely the details for Google^[13] accounts: ^[14].

SunTzu583 have put up for auction several lots with millions of logins and passwords in mailboxes Gmail and. Yahoo

The first batch of almost 5 million accounts is represented by three "lots": the first two contain 2262444 accounts each and are sold for $125.48 or 0.1298 bitcoin, and the third contains all 4928888 accounts at once. The cost of the last lot is $200 or 0.206 bitcoin.

According to the seller's assurances, in this set, all passwords for accounts are decrypted.

The authors of HackRead, having analyzed the data provided by the seller as an example for free, were convinced that their sources were major leaks of previous years; in particular, from LinkedIn (when hackers managed to hijack 117 million accounts), Adobe (154 million accounts were stolen) and Bitcoin Security Forum (from where 5 million passwords to Gmail leaked). BSF is precisely the source of most of the accounts currently on sale.

The seller honestly warns that not all passwords will work on Gmail now. Leaks have been widely reported in the press, so it is hoped a significant proportion of affected users have changed their passwords.

In addition to these 5 million, SunTzu583 sells almost 22 million more Gmail accounts for $450 (0.4673 bitcoin). Despite the fact that the number of accounts in this set is four times higher, the cost of the second set is only two times higher than the price tag on the first. This is due to the fact that in it only 75% of the offered accounts are available out of the box - passwords in them are presented in the form of text. The rest of the passwords are cached.

The authors of HackRead found that several leaks of different years became the sources of this data, the largest of which was the Dropbox hack in 2012. Then the data of 68 million Gmail accounts were stolen. These details were shared only in 2016. Other sources of these accounts were leaks from Nulled.cr in 2016 and MPGH.net in 2015.

Data of 33 million employees of IBM, Dell, AT&T, Boeing and other corporations stolen and posted on the Web

A very large database with the contact data of millions of employees of American corporations has leaked to the Web. The database contains 33.7 million unique records, which contain postal addresses, full names, names of positions and functions of employees, and other information of varying degrees of confidentiality ^[15]].

The database contains data from employees of famous American companies, including those working in the ICT industry: AT&T, Boeing, Dell, FedEx, IBM, Xerox and others.

According to ZDNet, the database "contains dozens of fields," and, in addition to purely personal information, it also contains more or less publicly available information, such as the geographical location of headquarters and offices, the number of employees in each company and their industry affiliation - advertising, legal services, media and telecommunications.

This kind of data is used by marketers and advertisers to conduct targeted campaigns. The cost of such databases can be very high.

As stated in the publication ZDNet, in 2015, the cost of accessing half a million such records reached $200 thousand. Thus, access to the entire leaked database would be about $13.7 million.

The leaked database is owned (or owned) by the marketing corporation Dun & Bradstreet. She has so far reacted to the information about the leak only with a short statement: "We carefully analyzed the information received and concluded that it corresponds to the same type and is presented in the same format in which we provide data to our customers on a daily basis. Our analysis shows that these data were not obtained and replicated through the Dun & Bradstreet system. "

2016: Leaked bank data of 34,000 Acer customers

In June 2016, it became known about a major leak of confidential data of Acer customers. Visitors to the Taiwanese manufacturer's online store were injured. Read more here.

2015

Information security incidents in 2015 occurred almost every day. They had a wide variety of motives, ways of execution, scope and consequences. The Falcongaze think tank recalled the most high-profile cases of data leaks and prepared a monthly chronicle of events.

January - Target. Scrooge, who ruined Christmas, turned out to be a Target chain of stores in the past year. As a result of a large-scale leak, the attackers had credit card data of forty million buyers. The leak for Target ended with a $300 million loss, the resignation of the CEO and a pretty damaged reputation.

February - Anthem. In February, there was a message about the largest leak in the field of medicine. The hacker attack compromised the personal data of 80 million customers of Anthem, a health insurance company. Company officials have requested help from the FBI and the investigation is still ongoing.

March - Medical institutions. In March, the health sector was hit one by one. A number of American medical organizations suffered as a result of hacker activity. As a result of large-scale leaks in various medical institutions in Louisiana, Florida, Oregon and Indiana, the data of more than 220 thousand patients suffered.

June - LastPass. In June, terrible messages appeared in the media - passwords from the service were stolen, in which users stored passwords so that they would not be stolen. In fact, everything is not so bad: the attackers gained access to the email address, password reminder, salt and hashes of user authentication, that is, the accounts of the overwhelming number of users remained safe. Nevertheless, the leak caused a resonance and made you ask an important question: how secure is the software created for information security.

July - Ashley Madison. The most resonant leak of the year can rightfully be considered a hack of the dating site Ashley Madison. 33 million users of the site, which positions itself as a dating service for adultery, found their addresses and transaction history in the public domain. After that, a series of scandals began, related, for example, to the fact that most of the women's accounts on the site turned out to be fake, the service continued to store information about remote users, the addresses of politicians were found in the database, and the media disseminated the news of two suicides related to the leak.

August - Carphone Warehouse. In August, a cyber attack hit Carphone Warehouse, Britain's largest mobile phone retail retailer. Data on 2.4 million customers of the company (about 4% of the total population of the UK) were stolen, and among them 90 thousand credit card access codes. The UK Information Commissioner's Office took up the investigation into the country's largest leak.

September - Excellus BlueCross BlueShield. In September, the story with Anthem continued. The leak turned out to be even larger than first thought and affected customers of the BlueCross BlueShield association, of which Anthem is a member. As a result, more than 10 million records were compromised, including information about finances, social insurance numbers, addresses and names. The cause of the leak is still unknown.

October - Experian (T-mobile). October was marked immediately by a number of major security incidents, but the largest was the leak of information about 15 million users of the T-Mobile operator. The leak did not occur inside T-Mobile itself, but on the part of Experian, which is engaged in consulting, and is also a partner of T-Mobile in the field of attracting users. Information about all customers who conducted operations with T-Mobile through Experian between September 2013 and September 2015 was compromised.

November - VTech. The Chinese maker of "smart" toys reported in November about the data breach of 11 million customers, half of whom are minors. Hackers not only compromised customer data, but also gained access to correspondence and photos, videos and audio messages sent to servers.

And finally, in December there was the largest leak of personal information for the entire year. Researcher Chris Vickery accidentally discovered a database of 191 million Americans voting in the public domain. About 300GB of leaked data includes detailed personal information about compromised citizens, from name to phone number, and a history of electoral activity since 2000. Where this information appeared on the network and who is responsible for its distribution remained unknown.

2014

Leaks at McDonalds, HTC, Barclays, Microsoft

SearchInform also compiled a rating of the most high-profile incidents of 2014 related to leaks of confidential information at the end of 2014.

In January 2014, the McDonalds chain posted advice for employees on its corporate resource that you should not overuse burgers, cola and fries, since these products are not useful for the body. The "sincere recognition" of the global fast food giant caused a wave of reproaches and lawsuits addressed to the company.

Once one of the leaders in the smartphone market of NTS, which is going through far from the best of times at the end of 2014, a blow to the back was inflicted by its own employees, who are part of the highest echelon of the company's management. They stole commercial developments in order to create their own smartphone company in China. The ex-employees are awaiting trial. They were expected to receive real prison terms.

A very noticeable leak of personal data was made by the British bank Barclays in February, as a result of which hundreds of thousands of bank customers were among the victims. It is important to note that this leak of confidential information is different from other cases of data loss in that it was not accidental. Personal information was deliberately copied by bank employees for the subsequent sale of data on the black market.

Alexey Kibkalo from Microsoft was detained in March 2014 by the FBI. He was accused of facilitating the dissemination of commercial secrets of the company, as well as providing journalists and bloggers with products that had not yet appeared on official sale. The details of the case are here.

The top information leaks for the month of April are headed by the American leader in the field of information and analytical services Experian, which has lost accounts of about 200 million of its customers. The same month is famous for another case of a leak to KT Corp. from South Korea, which also allowed the loss of 12 million client data. These cases, which occurred in different parts of the world, are related to one thing - such an operation was carried out with the direct participation of corporate personnel, thanks to which access to information on the protection of the corporate network was opened for criminals. If the control over personnel was carried out properly, it would be much more difficult for hackers to carry out such an operation.

In May, the largest loss of personal data was noted by the world famous online auction eBay, which leaked information about several million users of the resource with addresses, phone numbers and other information to the network. A similar incident occurred with the well-known Steam game subscription service from Valve. However, we note that in this case this is a consequence of the unreliability of the software, and not the fraud of the company's personnel.

In the first place among the leaks of last summer, no doubt, information declassified by the Americans about their residency in Afghanistan can be placed. Do not forget about another employee, now former, Microsoft Corporation, Brian Jorgensson, who is currently serving his term for trading confidential information - he also received this term in the summer of 2014.

One of Nigeria's banks lost more than $40 million in September. The information leak occurred with the assistance of a system administrator who had recently lost his job at this bank. It is worth noting that in the countries of the former USSR, the main reason for the leak of information is associated with IT personnel. Data provided by the SearchInform research center suggests that almost a fifth of all leaks are directly related to staff.

Although October and November were not particularly rich in events related to the leak, the largest concern in America AT&T became involved in a rather large scandal, since one of the company's system administrators was able to gain access to confidential information about 1600 VIP clients.

According to experts of the analytical center of SearchInform (SearchInform), the bulk of lightning data leaks is due to an insufficient level of control over the actions of personnel at workplaces. Such expensive days of them, the mistakes of large corporations can be a good lesson, thanks to which it will be possible to protect your business from losses caused by personnel, as well as save a lot of money that can otherwise be spent on eliminating the consequences of data leaks.

Biggest leak in history: 1 billion accounts stolen from Yahoo

The largest leak of the now known affected half a billion people - this is how many accounts were stolen from Yahoo: hackers gained access to personal data of more than 1 billion users, including their logins, passwords, email addresses and even phone numbers.

In

March 2017, the US Department of Justice formally charged three Russian citizens and a citizen of Kazakhstan with hacking into Yahoo Corporation servers in 2014, as a result of which 500 million mail accounts were leaked. Of those four, two in the charge are named as intelligence officers, while the other two are named as hackers "hired by the Russian authorities." Read more here.
