Surabaya, IT Journalistic — Another proud achievement has been accomplished by students of Institut Teknologi Sepuluh Nopember (ITS), particularly from the Faculty of Intelligent Electrical and Informatics Engineering (FTEIC). Team Manarul Ilmi Enjoyer successfully secured 2nd Place in the Capture The Flag (CTF) category at National Cyber Week 2025, organized by Cyber Security Bina Nusantara University.
This achievement reflects the strong competence of ITS students in the field of cybersecurity, while also reaffirming the strategic role of FTEIC in nurturing nationally competitive digital talent.
Team Manarul Ilmi Enjoyer is a cross–study program team within FTEIC ITS, consisting of Umar Baharun and Evandra Raditya Fauzan from the Information Technology Department (Class of 2025), as well as Daniel Dhaniswara from the Software Engineering Study Program (Class of 2025). This interdisciplinary collaboration became a key strength in tackling the complex and multidisciplinary challenges of the CTF competition.
Umar Baharun explained that the formation of Team Manarul Ilmi Enjoyer was not an instant process. The three members have known each other since vocational high school and frequently met in various CTF competitions.

“Since vocational high school, we often met in CTF competitions and already knew each other. Coincidentally, all three of us enrolled at ITS, so we decided to form a team together,” said Umar. This familiarity and shared experience enabled more effective coordination throughout National Cyber Week 2025.
The team’s interest in cybersecurity originated from the nature of CTF competitions, which challenge logic, creativity, and problem-solving skills. According to Umar, CTF offers a unique experience that requires participants to think critically and adaptively.
“CTF is fun—it feels like solving digital puzzles. We’re challenged to think logically and find solutions using various approaches,” he explained.
At National Cyber Week 2025, the CTF competition adopted a Jeopardy-style system, where participants faced various challenge categories, including cryptography, web security, forensics, reverse engineering, and binary exploitation (PWN).
Among all categories, binary exploitation (PWN) was considered the most challenging for the team. Nevertheless, a clear division of roles allowed Team Manarul Ilmi Enjoyer to work efficiently and effectively.
“Task distribution is directly adjusted to each member’s skill set. Evandra handled web exploitation, I worked on cryptography and forensics, while Daniel focused on reverse engineering,” Umar explained. This strategy enabled parallel problem-solving and maximized each member’s contribution.

The academic background at FTEIC ITS also played a significant role in shaping the team’s mindset during the competition. The Software Engineering Study Program enhanced awareness of security aspects in application development, while the Information Technology program provided strong foundations in networking and systems.
“In Software Engineering, we become more aware of security in application development, while in Information Technology, networking fundamentals are highly applicable in CTF competitions,” Umar added.
As a closing note, Team Manarul Ilmi Enjoyer shared tips for FTEIC students and other students interested in pursuing cybersecurity and participating in CTF competitions. According to the team, teamwork, consistent learning, and reading write-ups from previous competitions are crucial for expanding insight and problem-solving strategies. Technical preparation is also essential. “Prepare your environment early—tools, scripts, and everything you need. Don’t wait until the competition starts to set things up,” Umar advised.
The achievement of Team Manarul Ilmi Enjoyer is expected to inspire ITS students, especially within FTEIC, to continuously develop competencies in cybersecurity and confidently participate in national and international competitions. This accomplishment aligns with the support of the Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education) through improving students’ technological competencies, SDG 9 (Industry, Innovation, and Infrastructure) through strengthening innovation and information security, and SDG 17 (Partnerships for the Goals) by encouraging collaboration among students, educational institutions, and competition organizers in building a sustainable cybersecurity ecosystem.
