Walkthru

A. https://prasannakumar.in/infosec/vulnhub-ctf-usv-2017-writeup/ [javascript Obfuscated  which is currently one of the best methods for protecting JavaScript code from reverse engineering. The "var _0xbb15=" gives us a hint . It’s in the obfuscated way. Deobfuscating using JS Beautifier, vulnerability with https: site, decode or reverse engineer the math manually, curl to download an html page using --data (POST) request, LFI or local file inclusion , curl to read /etc/passwd due to LFI,
wfuzz to fuzz/customize the dir structure to download, one can use wget to download the files from door and vault folders by selecting '--no-directories’  options so it doesn't create ten thousand directories but wget didnt stop automatically, it kept on going , may be does multiple iteration not sure ,aircrack-ng, looks like a blind sql injection and we are not getting response from the SQL injection error or select statement in that case we know the sql injection worked if we see output and when con content is shows means it is false or didn't work or doesnt exist , possible firewall blocking union based statements, limit SQL function, SQL union queries]

Penetration Testing Framework 0.57

Network Footprinting (Reconnaissance) The tester would attempt to gather as much information as possible about the selected network. Reconnaissance can take two forms i.e. active and passive. A passive attack is always the best starting point as this would normally defeat intrusion detection systems and other forms of protection etc. afforded to the network. This would usually involve trying to discover publicly available information by utilising a web browser and visiting newsgroups etc. An active form would be more intrusive and may show up in audit logs and may take the form of an attempted DNS zone transfer or a social engineering type of attack. http://www.vulnerabilityassessment.co.uk/
