A Security wargame

What is CTF?

Capture the Flag is an information security competition that is an amalgamation of various challenges that applies concepts like Reverse engineering, Web Applications, Binary, Network, Cryptography, Forensics, etc. Each challenge holds a certain number of points based on its difficulty level. The idea behind these CTFs is to provide an individual practical knowledge of the different kinds of attacks and issues in the real world. For aspiring white hats, CTF challenges are a good thanks to learning hacking techniques, strengthen your problem-solving skills, and gain critical hands-on practice. CTF competitions deal with the correct level of pressure to stay things interesting while helping you to sharpen your skills. For the pros, CTF competitions facilitate your assess your skill level, challenge yourself among peers, and perhaps even earn some bragging rights.

In computer security Capture the Flag (CTF), “flags” are secrets hidden in purposefully-vulnerable programs or websites. Competitors steal flags either from other competitors (attack/defense-style CTFs) or from the organizers (jeopardy-style challenges).

cybersecurity capture the flag is a team-based competition in which participants use cybersecurity tools and techniques to find hidden clues or “flags”. The team that locates the most flags during the event wins. These events are often entry-level and open to the public.

When a player is in an opposing team’s territory, they can be captured by that team’s players. If they tag the player, the player must perform a task—say, five jumping jacks or three push-ups—before returning to their own territory.

Capture the Flag (CTF) is a special kind of information security competitions. Well, attack-defence is another interesting kind of competitions. Here every team has own network(or only one host) with vulnarable services. Your team has time for patching your services and developing exploits usually.

One of the CTFs that was particularly interesting to me was the Google CTF. One can opt to go for the beginner challenges to see where the skill level really was at – and although it is “mostly” easy, there are still some challenges that can make the competition tough.

CTFs enable you to develop your problem solving and analytical skills to use in real-work scenarios. CTF tasks are usually based on real-world vulnerabilities and security incidents. Nowadays, CTF problems are asked in job interviews to test the skills of professionals.

CTF course in Bangladesh is provided by cybersecurity professionals who are penetration testers at hackers last. In the CTF course in Bangladesh, you will master objectives including Intrusion Detection, Policy Creation, reconnaissance with Social Engineering and Google, DDoS Attacks, etc.
The categories of CTF include:
RE (reverse engineering):get a binary and reverse engineer it to search outa flag.
Pwn : get a binary and a link to a program running on a foreign server. Cause a buffer overflow, etc. to bypass normal functionality and acquire the program to read the flag to you.
Crypto :crypto means cryptography! Get an encrypted flag and work out a way to decrypt it (includes both classical and modern ciphers)
Web :web-based challenges where you’re redirected to an internet site, and you’ve got to search out and exploit a vulnerability (SQL injection, XSS, etc.)to urge a flag.
Forensics/ Stego :given a PCAP file, image, audio or other file, find a hidden message and find the flag. Other: this can be a small amount of a grab bag. Includes random puzzles, electronics-based things, OSINT, anything that doesn’t fit in to the opposite categories.
