ID card “The Lessons We Learned” conference

Estonian Information System Authority (RIA) is organising an international conference on 9th of May in 2018 in Tallinn (Tallinn Creative Hub – Kultuurikatel) to discuss the impact and consequences of the security risk found in the Infineon chips in autumn 2017 by the researchers at Masaryk University in the Czech Republic.

The aim of this conference is to bring together parties affected by the security risk to discuss our lessons, experiences and responsibility, because the security flaw affected many companies and countries in Europe as well as elsewhere in the world. If possible, we aim to agree on a joint plan of follow-up activities or a memorandum to provide input to different authorities who establish regulative rules. Researchers from Masaryk University have announced their participation in the conference – they will make an opening presentation about their research.

The conference is aimed at policymakers as well as specialists in the eID field, opinion leaders, representatives of authorities and companies that are dependent on the functioning of Estonian ID-cards and e-services, developers of e-government and IT systems, and other parties related to the issue from both Estonia and Europe.

Study on the lifecycle of cryptographic algorithms 2017

This year we have ordered and will publish cryptographic algorithms life cycle report in parts. The first part is now available.

The first and the most important chapter gives overview of the current state of algorithms.

The second chapter writes about the cryptographic side of the last fall ID card crisis. The report describes what happened, what was done and how on the cryptographic side the new solution (elliptic curves) for ID cards works.

The third chapter gives overview of block-chain technologies and in addition provides Estonian-language terminology for block-chain related English terms.

The report has been ordered by RIA and written by Cybernetica researchers Ahto Buldas, Jan Willemson and Arne Ansper.

Estonian intelligence chief invites hackers to work


The Estonian Foreign Intelligence Service (Välisluureamet) was previously known as the Estonian Information Board (Teabeamet).

This world is very fast and very good experts are required. Your homepage, which has become a little more informative recently, suggests that you are also looking for new people?
Of course we are looking. Do not we compete on the same market as other public authorities and the private sector? If we are talking about a big data or a better use of public sources in obtaining our information, then everyone with this competence is very much in demand.

At the end of the annual report (Estonian version), I found one challenge. These who can solve this could work for you?
Since we have a publication once a year, where we talk about our work openly, we also intended to use this publication to expand our recruiting field. If people reach to the last page of the document, then there may be some who can solve the puzzle and send the solution to us. I can not guarantee that the solution ensures a job, as other processes need to be followed. However, it definitely shows that the person has competence and analytical mind in cryptography.

You are giving interviews that would have been a big surprise many years ago. You reject the public myths about intelligence work. Your agency publishes puzzles to find potential employees. What is the future of your agency?
Yes, over the last few years, we have come out of the shadows and closer to the public. My clear view is that if you are not in the picture then you do not exist. However, if we want to recruit the best specialists, it is very difficult to find people for an institution that does not exist. Of course, we must at the same time be aware of security, but these risks can be handled. But in the future of intelligence, there are two keywords: co-operation and technology.

Crypto challenge:

Signal intelligence was able to capture an encrypted message: SDZROZDBITGNUMYNSF
However, the receiver was unable to decrypt the message and the message was transmitted again: YHDRCRLBUTIPUCMFGF

Questions:
(a) What was content of the message
(b) What key was used to encrypt

The solutions can be sent to info@valisluureamet.ee with topic “Nuputamisülesanne”

The crypto challenge seems just as a way to get attention. We are living in times where end-point exploitation is the tool to obtain intelligence. The capability to break ancient substitution cipher is unlikely to help.

ETV showed sensitive information on the screen

On Tuesday, “Ringview” had the episode in which the reporter Jüri Muttika traveled around the editorial office of ERR and asked ETV TV presenters to demonstrate their handwriting. An embarrassing error by the video editors allowed the frame to be broadcasted, which contained “Terevisiooni” file transfer protocol (FTP) username and password, hence allowing everyone to view the content on the servers.

The clip shows that the TV presenters tried to hide their notebooks and computer screens from the camera, which makes it especially embarrassing – basically everyone was able to watch broadcast materials.

The error in ERR was quickly recognized and now the password should be changed. The topic is also up in Facebook IT-man’s group, where the IT people write jokingly: “No such user and password do not really hide anything.”

Wouldn’t we expect the ETV internal FTP server to be firewalled from the external world?

State confiscates first criminally obtained bitcoins

The employees of the Criminal Police organized crime department in the summer arrested a young man living in Estonia who sold large amount of different drugs on the darkweb. With the help from the cybercrime unit of the Central Criminal Police, the bitcoins earned from the sale of drugs were also obtained, which, by the present moment, based on the county court order have been confiscated. The information about the amount of bitcoins sized is not available.

According to the Prosecutor General Vahur Verte, it is true that identifying the owner of the crypto money and tracking the movement of money is more complicated, but certainly not impossible.

How did the police technically size the bitcoins? Were they transfered to state-owned bitcoin wallet? Who paid for the transaction fees?

Passwords of 200’000 Estonian social media accounts leaked

CERT Estonia, the organization responsible for the management of security incidents in .ee computer networks, informed nearly 200,000 Estonians via their employers that their social media passwords had been leaked. According to RIA, a database was created in Dark Web, containing 1.4 billion user information and a password in the open form. The database also contains email addresses with more than 190,000 ending in .ee.

For each institution, CERT sent a list of individual email addresses. “For example, if there were people from national broadcasting, let’s say mari.maasikas@err.ee, then we sent information to the head of ERR’s information security that the passwords of these people have leaked.” explained Mägi.

The number of Estonians at risk is much bigger, since most of the personal e-mail accounts are not using .ee domain. Some Good Samaritan could instead send out direct warning e-mails to all of the addresses in the database.

Reproducing Android Vote Verification Application Builds for Estonian I-Voting System

The main objective of this work is to check whether the vote verification applications distributed in the app stores can be compiled from the source code that has been made publicly available by Estonian National Electoral Committee. The experiments were performed using the Vote Verification application versions that were distributed in the I-voting period of the Estonian municipal council election held in October 2017.
The report will go through the different steps that were done during this experiment – monitoring the binaries, building the app from the source code, comparing build result with the distributed version and trying to reproduce it based on the differences found.

This is the report for UT course “Research Seminar in Cryptography (MTAT.07.022)”. The work deals with reproducible build problem of vote verification software used in Estonian i-voting held in October 2017.

The TL;DR; is that the source code available in GitHub is outdated and apparently was not the source code which was used to build the applications that were distributed to Android devices in Google Play Store.

Estonian cryptographer rejects claims of being Bitcoin’s creator

Los Angeles lawyer Justin Sobaje is convinced that Helger Lipmaa, senior researcher of the University of Tartu’s computer science institute, is Satoshi Nakamoto – the creator of bitcoin, and says he has analyses and studies that prove it.

Sobaje writes that he is convinced – based on an article in which Nakamoto first describes the nature of bitcoin – that the author or authors of the piece had to have been experts of timestamping technology and hash trees. That is the focus of Helger Lipmaa’s doctoral thesis and scientific papers published in the late 1990s. Lipmaa has cited another two articles the original creator of the bitcoin also cites on his homepage. Conclusion: Lipmaa knows five out of eight articles.

Sobaje continues: “Satoshi was an experienced C++ programmer. Lipmaa created timestamping software while working at Cybernetica.” He lists the years Lipmaa spent working for the company until two years before the birth of bitcoin. How was the name Satoshi Nakamoto created? Sobaje has found three Japanese cryptographers mentioned on Lipmaa’s website – Satoshi Obana, Junko Nakajima, Takeshi Okamoto – and concludes that the name of the world’s most wanted man is a combination of the three.

Helger Lipmaa, commenting on the matter to Postimees, rejects the idea. “I’m certainly not Satoshi and I don’t understand how he got to my name of all things,” he said, adding that bitcoin’s original creator wasn’t a cryptographer.

Professor of software science at the Tallinn University of Technology Ahto Buldas, who worked with Lipmaa on timestamping technology in the late 1990s, laughs out loud when told an American lawyer believes Lipmaa to be Nakamoto. “The number of scientists that worked on it at the time was not great, while there are other candidates for Nakamoto. I don’t want to say that Lipmaa is not Satoshi Nakamoto; even though I don’t really believe it, it cannot be ruled out either,” he says. “We could all have been Nakamotos.

This could be a potential topic for BSc/MSc thesis, to use open source intelligence to verify if there is some correlation between public activities of Satoshi and Helger/Ahto.
