Dutch data breaches (Aug 16)

A chronological list of digital data breaches in the Netherlands (in Dutch: ‘datalekken’), in as far as they have become publicly known, since November 2007. If you have an entry to add to this list, please mail Karin Spaink, and make sure to include a reference to a news publication describing the event. The idea to create this list arose after three severe incidents occurred in a single month; the example was taken from the Privacy Rights Clearinghouse Data Breaches list.

This list is about data breaches. It’s about the unintentional leaking of data, not about exploits, hacks and/or vulnerabilities. Hence, it deals with unsecured and ‘misplaced’ data rather than with stolen data; with actual leaks rather than possible security holes; and finally, with digital data rather than paper files. Sometimes, however, it’s not easy to draw a line, so some of the items listed might be debatable. I started the list in November 2007. Older data breaches are not listed.

Rejo Zenger maintains a similar list. His criteria are slightly wider than mine. He has also spotted some data breaches that I hadn’t read about; I’ve included those. Additionally, Rejo now maintains Bits of Freedoms’ data breach pages.

Aug 16, 2010 TV show leaks data 13.000
what: Breekijzer is a by now defunct tv show to which people could send their complaints about companies, institutes and government bodies; the program would select some of these complaints and attempt to help the complainers. All (or most) of the complaints that Breekijzer received are stored in an online database; once you had logged in to see your own complaint, you could easily see all other complaints by merely changing the complaint number. Thus, 13.000 complaints were retrievable. All complaints listed name, address, telephone number, e-mail address, and gender. Often, the complaint itself has a private nature.
response: Pieter Storms – the owner of the TV show – did not respond to warnings. In the end, his ISP took measures to prevent further leaking.

July 13, 2010 City leaks bank numbers unknown
what: Private data of people who have received a building license in Groningen, is visible via the city’s website. (One needs to apply for such a license when expanding one’s house or building an addendum to it.) Data disclosed are names, addresses, bank numbers, signatures and telephone numbers. In April of this year, the city removed the general index to all approved licenses when warned that it was thus leaking data, and considered the matter done. As it turns out, simply by increasing or decreasing the file number in a url.
response: None, as of yet..

July 13, 2010 Tour operator leaks bookings unknown
what: Dutch tour operator Corendon gives people who’ve booked via their site a client number and a booking number. Turns out that these are handed out sequentially, so by just increasing or decreasing the number in the query, one can see other people’s data. Visible were: destination, date of departure, return date, flight information, amount paid, amout left to be paid, plus information about all people booked: names, addresses, telephone number, date of birth.
response: Jeroen van der Gun discovered the leak and warned Corendon on June 28. On July 7, Corendon changed the login-procedure for clients, who now also have to enter an e-mail addreess to see their booking.

July 10, 2010 10% of hospital personnel fell for phishing test 1423
what: Erasmus MC, the biggest academic hospital in The Netherlands, puts quite some effort in security awareness and data hygiene. (They participated in my September 2006 Electronic Patient Files test, and did relatively well; also, they used the results of my test to again stress the need for data hygiene among personnel.) In June, the hospital tested its own personnel by sending a hospital-wide phishing mail, asking addressees to please give their
account name and password. 1423 people complied – slightly more than 10% of all Erasmus MC personnel.
response: The board summed up the results of their test in a new mail to all personnel, and started a new campaign for data hygiene awareness.

July 06, 2010 Psychiatric/criminal files dumped on street unknown
what: DPD, the District Psychiatric Service in The Hague – which keeps the psychiatric and criminal records of (former) detainees, dumped a box full of such records on the street, together with ‘other garbage’. A passerby found the box and reported the matter to the Dutch privacy authority (CPB). This was in January 2010. The CPB has now reported about the case and discovered that for years, all medical and criminal files of detainees were stored in an unprotected cellar.
response: The CPB reminded the Dpt of Justice and DPD that records like these are highly sensitive data and merit strong protection.

July 05, 2010 E-mail addresses disclosed 375
what: NLKabel – a field organization for cable providers – sent its daily newsletter to subscribers. The addresses of 375 of them ended up in the e-mail itself.
response: NLKabel confirmed its mistake.

June 06, 2010 City sends wrong file 2800
what: After requesting a directory of the services of city X, a citizen of that city was sent not that directory, but a file containing the names of the circa 2800 people living in that city who may not renew their passport or who have to hand in their passport. Reasons why people end up on this so-called Alert List: they’ve lost their passport too often (and are suspected of fraud or trafficking in passports); they owe the government money (taxes, fines, alimony); they’ve lost Dutch nationality; they’re bankrupt; or they’re involved with criminal offenses. Every city receives an Alert List from the Dpt. of Internal Affairs once per month.
response: The Dpt. of Internal Affairs will remind all city authorities to treat the Alert List as sensitive data, and considers to send it in the form of protected digital data in the future. Currently, the ALert List is sent in paper form.

May 28, 2010 Sensitive DoJ data published unknown
what: Various web sites have published ‘documents containing sensitive data’ from the Department of Justice’s national penitentiary task force (Landelijke Bijzondere Bijstandseenheid), who are called in when there are problems in jails. The nature and the scope of the leak is unclear, but it seems that the documents contain information about the task force’s organisation, including phone numbers.
response: The DoJ has asked the owners of the web sites concerned to remove the information and has taken ‘measures to minimalise the risk for its employees’.
references: Nu.nl, May 28, 2010
May 19, 2010 75% of NL companies have leaked data 168,000
what: A study by Accenture and the Ponemon Institute shows that 75 percent of Dutch companies have had a data breach in which they lost employee, client or customer data. That’s more than the global percentage, which stands at 58 percent.
references: Security.nl, May 19, 2010
May 18, 2010 Travellers’ info leaked 168,000
what: The web site Ervaar het OV (Experience Public Transport) is a government site promoting the new public transport chip card (OV card). Visitors can order a personal OV card, get reduction vouchers and special offers via the site. For months, the customers database could be accessed (and changed) via a simple MySQL inject; the data of the 168,000 people who have registered via the site were available. Their data included name, address, date of birth, telephone number and e-mail address of these people, and possibly their passport number and payment method. Hacker ins3ct3d proved the leak by retrieving all the data of a journalist.
response: After having been informed of the leak, the government closed the site. The OV chip card is mandatory in some regions in NL, and will be rolled out in others in the coming months. The SP (a political party) will motion for a freeze: this is the umpteeth vulnerability/leak with regard to the OV chip card.

May 04, 2010 Bank dupes duped several dozen
what: Many people who were duped by DSB Bank going broke, joined the foundation Hypotheekleed (‘mortgage pains’). One of them suddenly started to receive e-mails containing the names, data and mortgage information of other members. Apparently, this happened because one of the employees of the foundation entered the wrong e-mail address.
response: Hypotheekleed admitted the error and promised to be more careful in the future.

Mar 01, 2010 Data of medical applicants leaked unknown
what: The data of people who applied for a specialization as general practitioner after having finished their primary medical education, leaked via the website Huisartsenopleiding. Appending a first name to a specific url was sufficient to see all of the applicant data: address, date of birth, SSN, medical ID number, education, diplomas, previous jobs, etc., if an applicant with that first name existed.
response: Huisartsenopleiding was rather shocked and immediately modified their website.

Feb 27, 2010 Tax papers of civil servants leaked several hundreds
what: The 2009 tax reports of all civil servants, city council members and assistants of the municipalty Woudenburg/Scherpenzeel were leaked; newspaper De Telegraaf received a paper copy of all papers. The papers include name, address, SSN, salaries, other income, bank savings, deductions etc of everybody working for the municipality and the city counci, from the mayor to the members of the fire brigade. It’s unclear how the data were leaked and why they were sent to the press.
response: City Hall has asked the police to investigate the matter.
references: De Telegraaf, Feb. 27, 2010
Feb 26, 2010 Data of candidates 2006 election leaked several hundreds
what: Private information such as telephone numbers and home address of all candidates for the 2006 national election were leaked, including the address of prime minister Balkenende and several other members of the government. The data were leaked via open directories on the websites of the Zaandam and the Lith municipalities. (During the 2006 elections, many municipalities used the Nedap voting computers. The candidate lists were fed into the computers and apparently, Lith and Zaandam put this information in an unprotected directory.)
response: The open dirs were closed; Google’s cache still reveals the documents.
references: Webwereld, Feb. 26, 2010
Feb 25, 2010 Students info often leaked several thousands
what: The teachers union (Algemene Onderwijsbond) researched how often student information is accessible via Google. They found quite a lot: list of home addresses, student reports, progress reports, assessment reports. The union notified all the universities, faculties and training colleges that were at fault. It’s the second time that the Algemene Onderwijsbond embarked on such a student privacy scan.
response: Most colleges and faculties remedied the situation as best as they could.

Feb 25, 2010 Data on hundreds of politicians leaked several hundreds
what: The addresses, telephone numbers, mobile phone numbers, home e-mail addresses and work e-mail addresses of hundreds of politicians (all members of the PvdA, the Dutch social democrats) and a number of their sponsors are out in the open. Although the list focuses on party members in the Amsterdam area, it also contains the data of the chair of the Dutch Parliament and several members of the European Parliament. Google has indexed the file.
response: A few hours after the news was published and the owners of the website were contacted, they managed to close the open directory.

Feb 08, 2010 Notary puts clients passports online several hundreds
what: Veilingnotaris.nl tries to list all online real estate auctions. Apparently their site is badly protected: Google has indexed quite some client information, including passport copies, notary deeds, registry information etcetera. The published information concerned both recent and old auctions.
response: Internet Notaries, the owner of veilingnotaris.nl, denied all responsibility. ‘All similar agencies publish this kind of information’, they claim, ‘and besides, it’s the responsibility of the notary who’s doing the auction.’

Jan 29, 2010 University of Utrecht leaks pay slips unknown
what: Randstad HR Solutions, which apparently takes care of the pay roll information of the employees of the University of Utrecht, made an error. Employees did not only receive their own January pay slip and yearly overviews, but also slips and overviews intended for others. Randstad HR Solutions stated that the error was made by TNT Cendris, who delivered the slips and overviews.
response: The University sent a mail to all employees informing them of the error, asked them to destroy the envelope, and will send out new pay slips and yearly overviews. Almost two weeks later, the University stated that the extra slips had only been sent to the administration office and that no data had been leaked.

June 17, 2009 Emergency info leaked online unknown
what: The information that emergency services such as ambulances send to one another, was transmitted unencrypted. Because the C2000 system in Brabant (a Dutch province) didn’t have full coverage, emergency services used P2000 instead, which sends unanonymized data: name, address, ailment etc. In one case, information was put online containing the information of a suicide attempt gone wrong.
response: Brabant will get more extensive C2000 coverage.

May 30, 2009 Two telco’s hand over sms contents to intelligence unknown
what: Telco’s Vodafone and T-Mobile decided it was to much hassle to separate traffic data from content.

Dec 12, 2007 Vecozo (health insurance) almost all insured people
what: Vecozo, an organisation set up by health insurance companies, has created a password and certificate protected web site where professionals can check whether patients are indeed insured.

In other words: 1 out of every 200 in NL has access to the site. One can access name, date of birth, address and social security number of those insured. It’s possible to find the addresses of well-known people and of people who have secret addresses (for instance, battered women who’ve fled their husbands).
response: Vecozo declared that one could not access telephone numbers and refrained from all other comments.
