OpenSource licensing with Dr. Till Jaeger and cyberstorm.mu
I should admit that it was really an informal meeting over some beers, juice, Dame-Blanche, and Pizzas with Dr. Till Jaeger. It was very fruitful and amazing to the team. We received lots of advice for ourselves as well as for the cyberstorm.mu team. Some days back, the National Computer Board conducted a workshop on Opensource licensing which where Dr. Till Jaeger was the main resource person to deliver this workshop. Thanks to the National Computer Board for making this event a success. Cyberstorm.mu members were also invited to the event.
We have also welcomed Rahul Golam for joining cyberstorm.mu team and looking forward to work together. I seized this opportunity to announce that cyberstorm.mu is proud to announce it’s the official logo. Thanks to the hard work of the team.
We are for free and opensource software. We are presenting Mauritius worldwide in the IT sector. We are a Linux and Open source group which is going further and beyond. We believe in collaborative work and team spirit. We believed in running codes. We strived for excellence. We have contributed codes in several popular applications. We have worked on Internet-Drafts. We participate heavily in Hackathons.
The next step of cyberstorm.mu is championing several tracks for the IETF 103 hackathon remotely at Bangkok, Thailand. We have been welcomed by many people both from Mauritius and overseas, even from Silicon Valley, USA. No wonder, our past achievements is now a new step to reach today’s objectives – To focus heavily on research and development. Loganaden Velvindron from cyberstorm.mu mentioned on his Medium blog about the change cyberstorm.mu want to achieve: “The namecyberstorm.mu is an interesting one. It’s about change coming. Don’t get me wrong: I still love hacking. For me, hacking is about finding clever solutions to problems.” The youngest guy from the team is also going to participate in the IETF 103 hackathon.
I thank the guys of the National Computer Board who welcomed me, Logan and Codarren on their stand at the Infotech 2018. For those who are not acquainted with the Infotech event in Mauritius – “INFOTECH is the major annual Information and Communication Technology (ICT) event organized in Mauritius by the National Computer Board (NCB) in collaboration with the Ministry of Technology, Communication and Innovation. The aim is to create awareness on emerging technologies and provide business opportunities in the ICT sector.”
On reaching there, we met with Mr. Ismael and Mr. Riyaad and other staffs of the NCB, who provided us with a huge screen for our presentation and showcase of Linux, TLS1.3, DNS Security, IETF, Google Code-In and Google Summer of code events. I had the opportunity to meet several people including businessmen, students, and other geeks in the Mauritius IT industry.
Next, to the NCB stand, we had the CSE robotics club where I met with Chromiko who gave me some of his stickers. I still have some to share. Who wants one?
I also had the opportunity to shed some lights about Google search methodology and Computer networking with some students.

They are Anup Kumar Khadoo, Shamutally Shahabudeen Mohammad Arfhaan, and Gowardun Madhav who are Computer Networking students at MITD. The following example was illustrated: Imagine you want to look for PDF books on Computer Networking. One of the technique to search more rapidly is by typing:
index of: computer networking (pdf|doc)
In case you want to ignore certain results; assume the word ‘wireless’, we can try this as search techniques on google search engine by typing:
index of: computer networking (pdf|doc) -wireless
We also had the opportunity to talk about computer networking topics such as Wireless Security, Subnetting, and others. Whilst returning home, I seized the opportunity to shoot this beautiful view.
The cyberstorm.mu team has been participating in several IETF hackathons these recent years. For the IETF 102 hackathon, we focused tremendously on innovation: The goal to create two teams for the TLS 1.3 project, one for the Implementation team and the other is Interop. At the same time, getting hands on the HTTP 451 project. The IETF hackathon encourages developers to collaborate and develop utilities, ideas, sample code and solutions that show practical implementations of IETF standards. It is not a competition but a collaborative event.
For this IETF hackathon, myself and Loganaden Velvindron core members of cyberstorm.mu team decided to lead the event. We searched a marvelous venue at Pointe aux Piments, a remote coastal area in the north-west of Mauritius which was very peaceful and can accommodate the whole team including first-timers of the IETF hackathon for three nights. As regards food, the best place is at Triolet, a village nearby which is famous for street foods including Pizza, Indian food, Grilled, Burgers and Brianis. We also chose that venue as it included a WiFi hotspot, several rooms, bathrooms, and even a swimming pool.
On day 1, we all set up our lab environments and since most first-timers were in the TLS 1.3 Interoperability team, a plan was already designed. We knew since the beginning that there would be the logistic issues, so we brought spare laptops, screens, memory card, projector, etc.. Logan explained the situation we had to deal with especially when it comes to interoperability to the first-timers. Then, they assigned themselves some tasks. At first, it was time-consuming to get started, but at the end of day1, I can feel how everyone was working as a team and looking in the same direction for the TLS 1.3. On the other hand, Veegish was getting hands-on HTTP 451. Whilst the Interoperability team was having fun, the implementation team, on the other hand, was yet another challenge: Improving source code for TLS 1.3 compat layer.
On day 2, everyone woke up early and went for a morning walk. Afterward, the team was back to coding and debugging. Whilst some were on the implementation and Interoperability tasks, Veegish already advanced on the HTTP 451 project. A debrief carried out by logan to understand where the team stands. We had to constantly evaluate ourselves so that we knew in which direction we are moving. At the end of the day, most of us were already in the pool for some chilling moments. I seized the opportunity to make a Time Lapse video with my iPhone 7+ 🙂
On day 3, the atmosphere was intense. The implementation team needs to make sure the code has been tested and it is running correctly. I was heavily involved in the PHP CURL library part. The testing part was very challenging. At some moment I was so tired and hopeless as the testing part was really complex. At the same time, others were trying to help each other. Kifah was also on some bash scripting for the interoperability part. He wanted to automate some tasks. Logan was also looking at his code and helping the others. Well, at the end of the day we were so happy to be able to accomplish what we had planned. Everyone looked so tired. The only option is to go back to the pool.
We also decided to make some mini videoS to relate our experience during the hackathon. I uploaded the videos on YouTube. You can view it from the playlist below:
On day 4, we packed up to our destination. At that very moment in Montreal, the hackathon was still going on. I reached home at about 19:00 hrs Mauritius time. I was assigned a three minutes presentation for the hackathon carried out by the Mauritius team. It was already midnight. I was so tired. I knew that the presentation had to be carried out. Logan was constantly texting me to make sure that I did not fall asleep. You can view the presentation remotely live in Montreal Canada.
What did IETF hackers say about the IETF 102 hackathon?
“What I think was the most productive output during this time for me was pair-programming…”– Kifah
“I was very excited to be part of the Inter-operability team where I worked with OpenSSL, BoringSSL, WolfSSL, and tlslite using TLS1.3 protocols.”– Jagveer
“Making Internet Protocols great again during the IETF 102 hackathon” – Logan
“Finally after long hours of debugging he managed to test the protocol being used by NRPE locally”– Rahul
“Then… we finally got a Client Hello from Wireshark and made the PR”– Nigel
“At first I thought that it would only be working, working and working but besides of work we started creating bonds.” – Jeremie
“I got a lot of advice, support, and motivation to work with my team members and try to implement on a strategic basis and critical thinking the internet protocols and see their limit on a technical perspective.” – Avishai
“Once OpenSSL was installed, I then performed my first TLS 1.3 Handshake, Resumption, and 0-RTT but did run into difficulties with NSS.”– Chromico
“But while everyone is waiting, we are working. We have reached a deeper understanding of how it will affect our lives.”– Codarren
“IETF 102 was a very fun and challenging experience in which I got to work on several opensource projects” – Muzaffar
“At first, I did encounter some issues like parsing JSON files, but I manage to work on those issues”– Veegish
We also had a follower on Twitter appreciating our effort and participation during the IETF 102 hackathon. Thanks, Dan York, senior manager at ISOC.
I’m happy that this hackathon was at the required level. It was a great initiative from the cyberstorm.mu team. No major incidents occurred in our HQ at Pointe aux Piments. Everything that was planned went all and it’s worth investing yourself in this collaborative event.
Apart from the IETF hackathons, the cyberstorm.mu team also focused on internal hackathon either remotely or on-site participation. Another remote hackathon was already in progress since Saturday the 16th of June 2018. It was named Operation JASK – Just a Single Keystroke. Announced publicly on Sunday the 17th of June 2018 after noticing that several Crypto currency mining tools were vulnerable to CVE-2018-12356. By the time, many members of the team were already mobilised even if it was a public holiday in Mauritius. The operation was named JASK – Just a Single Keystroke as the security issues is concerned with the hardening of a regular expression, in particular requiring [GNUPG:] to be at the beginning of a line (^\[GNUPG:\]). We had to fire a single keystroke at the right place to fix a single vulnerability.
Marcus Brinkmann, who is a free software activist explained “An issue was discovered in password-store.sh in the pass in Simple Password Store 1.7 through 1.7.1. The signature verification routine parses the output of GnuPG with an incomplete regular expression, which allows remote attackers to spoof file signatures on configuration files and extensions scripts. Modifying the configuration file allows the attacker to inject additional encryption keys under their control, thereby disclosing passwords to the attacker. Modifying the extension scripts allows the attacker arbitrary code execution.”
However, simply the patch is, the attack aimed GnuPG signature verification process which is specific to pass the Simple Password Store. It can give the attacker access to passwords and remote code execution. On theRegister.co.uk – Pass gets a fail: Simple Password Store suffers GnuPG spoofing bug, Loganaden Velvindron core member of the cyberstorm.mu explained, “It’s hard to identify just how many downstream projects inherit a vulnerability as the one Brinkmann spotted, but the number of problem projects will likely be non-trivial because the GnuPG cryptography suite has applications beyond e-mail protection.”
