The Lancang-Mekong Regional Cybersecurity Competition is part of the Lancang-Mekong Cybersecurity Week and Cyber Competition initiative, organized by the Ministry of Post and Telecommunications of Cambodia (MPTC) with support from the Lancang-Mekong Cooperation Special Fund. In July 2026, MPTC hosted the Lancang-Mekong Regional Cybersecurity Forum, which brought together government officials and CERT professionals from LMC member countries for a three-day of dialogue on emerging technologies and regional cybersecurity challenges.

Building on the forum, we are delighted to be organizing the upcoming Lancang-Mekong Regional Cybersecurity Competition that gathers university students from across the region for training and a Capture the Flag (CTF) competition. It aims to build practical cybersecurity skills, encourage knowledge exchange and strengthen the Lancang-Mekong Cooperation among young people. The event is scheduled to take place on 10-12 November 2026 in Siem Reap, Cambodia (the exact venue will be shared later directly with the participants by email).

This CTF (Capture the Flag) is a cybersecurity competition where teams solve hands-on challenges to earn points and climb the scoreboard. Categories include OSINT (finding information from public sources), Pwn (exploiting vulnerable binaries), Reverse Engineering (analyzing compiled programs), Forensics (recovering evidence from disk images, memory dumps, and network captures), Cryptography (breaking weak ciphers and flawed implementations), and Web Security (exploiting application vulnerabilities), plus a Teamwork Challenge that no single player can finish alone and requires members to combine their skills.

Joining a CTF builds real-world security skills, sharpens problem-solving under pressure, strengthens teamwork and communication, introduces new tools and techniques, and gives you a portfolio-worthy achievement that stands out to universities and employers, all while competing for recognition on the leaderboard.

Tournament Rulebook

Guidelines & Competition Regulations

Essential check-in documents, technical laptop requirements, tournament rules, code of conduct, and organizer provisions.

Documents (checked at check-in)

International Participants: a passport valid for at least 6 months after arrival, and a visa if required.
Cambodian Participants: a national ID card or passport.
Names on documents must match the registration exactly. Participants who cannot show valid identification may not be allowed to compete.
A nomination letter from the nominating institution (if any).

Technical Requirements / Equipment

Each participant must bring their own laptop. Suggested minimum specification:

Suggested Minimum Hardware

8 GB RAM (16 GB recommended)
Modern dual-core or better CPU, at least 50 GB free storage
Working Wi-Fi adapter
Own charger, with a plug adapter (Cambodia uses types A, C and G).

Network & Tooling Environment

Wi-Fi only. No wired connection is provided, so laptops without Wi-Fi cannot be used.
Install and test your software and tools in advance.
Organizers provide power and Wi-Fi.

CTF Rules & Fair Play

Participants may collaborate with members of their own teams only, but must not share flags, solutions, hints, or write-ups with other teams during the competition, or coordinate with them in any way. Doing so will result in disqualification.

Prohibited Actions (Strictly Disqualifying)

Attacking any machine or IP address other than the designated challenge targets.
Attacking, disrupting, or overloading the CTF platform, servers, or other participants’ systems, including denial-of-service (DoS) attacks.
Modifying or tampering with the scoreboard or scoring engine.
Preventing other teams from flagging or solving challenges intentionally.
Any other deliberate misconduct that harms the platform, infrastructure, or other teams.

AI Tools & External Help

AI tools are allowed to help solve challenges, but must not be used to attack anything outside the designated challenge machines, or to overload or disrupt the CTF infrastructure. All prohibited actions above also apply to AI-assisted activity.
If a challenge seems unsolvable for an unintended technical glitch, inform the organizers immediately for troubleshooting.
If you need help, raise your hand or visit the CTF desk. Organizers can assist with platform questions, but will never provide hints or answers.
Do not photograph or record other teams' screens.
Participants must follow all event security measures, including baggage inspections. Weapons and illicit substances are strictly prohibited.
The organizers reserve the right to disqualify any individual or team for cheating, misconduct, or regulation breaches.

Challenge Format & Scoring

The CTF will have jeopardy-style tasks. Each task is allocated a dynamic/fixed point value, and teams receive points for capturing flags and submitting them successfully.
Challenge Categories: OSINT, Pwn, Reverse Engineering, Forensic, Cryptography, Web Exploitation, and Team Work.
Challenges are designed at a hard level for elite university teams.
Teams will be ranked according to their total score. If there is a tie, the team that reached the score first will be ranked higher (tie-break by submission timestamp).

Code of Conduct and Integrity

Be respectful and courteous to everyone, and respect their privacy and personal information.
No harassment or bullying, whether verbal, physical or online.
Be a good sport and play fair.
Do not cheat or plagiarize. This includes copying someone else's work or private repositories.
Report violations or problems immediately to the organisers.
Cheating or misconduct may lead to immediate disqualification and revocation of awards.

Photos and Videos Protocol

Organizers will take photos and videos throughout the event, including the learning sessions, the competition, and the closing awards ceremony.
These materials may be used for official event reporting, regional promotion, archives, websites, social media, news outlets, and partner channels.
By registering, each member agrees to this protocol. The team leader confirms this on the registration form, and each member acknowledges consent.
