Exploitation of Metasploitable Linux- Ep 1

The video below shows a demo of how to exploit the Metasploitable Linux using a backdoor. After the gaining of access, we then show a few commands in Linux that a hacker can run. In addition to that, we also check the permissions associated with the user profile we have accessed and surprise, surprise, it's Amy Acker (read Root).

After that, we then show u the contents of /etc/passwd and /etc/shadow- which when brought together give u the passwords file. However, we won't be getting the passwords file that way. There is a much simpler way I call "Post-exploit exploits". Among these, is one nifty one called gather/hashdump used to gather/get a hashdump of the passwords file.

We then take this hashdump to john (also known as john-the-ripper to others) who then proceeds to crack the passwords. In our case, the passwords used are quite simple so the process of cracking won't take much time. However, the more difficult to guess the password is, the harder it is to crack.

After we get a set of passwords and their respective usernames, we then use one of them to connect to the Metasploitable VM using telnet. In this case we chose the userid "user" which has the password "user".... Anyway, so you basically enter those credentials when using telnet, ssh or any other remote connection protocol listed in the nmap scan we did initially and hey! bob's your uncle.

Password Cracking: RainbowCrack table generation, sorting and usage

I had to do this demo after one of my students asked for my assistance regarding how to use this tool. Usually, I just assign different tools to them individually depending on the aspect of penetration testing we are covering (session hijacking, vulnerability scanning, etc) and then tell them to submit a report and a video demo of how the tool is used. Anyway, after a brief one-to-one discussion I realized the student had actually done the research on how rainbow tables operate (above and beyond the material in the lecture slides) so I figured that if he was here asking for assistance, he genuinely needed it. The tool is available at the RainbowCrack site. A detailed description of this nifty tool can also be found here . So, firstly I had to generate the rainbow tables. The command line syntax is: rtgen hash_algorithm charset plaintext_len_min plaintext_len_max table_index chain_len chain_num part_index where: hash_algorithm Rainbow table is hash algorithm sp...

Forensics: Extraction of email evidence using Wireshark and NetworkMiner

The video at the end of this post is a demo of a solution to a forensic challenge from this site . The goal of the challenge is to extract necessary information for an investigation from a pcap file. the site, forensicscontest.com, has a number of similar challenges that you can try out as well. Obviously, there is more than one way to skin a pcap (the other methods can be found among the solutions/walkthroughs on the site itself) and in this case 2 tools were used: Wireshark NetworkMiner Just to cover a few "mysterious" sections of the video, there is a point where I sorted the packets in wireshark in alphabetical order then looked for the first SMTP packet. The reason is that since we are investigating email evidence, the common protocols we should search for include IMAP, SMTP etc. In this case, the criminal used SMTP. Next, there is a point where we highlight the stream index in the detailed section of the packet. This is because each stream refers ...

How I Recovered my Corrupted 2TB Hard Drive without having to copy everything to another Drive

So, a little back story. I have a 2 Terabyte external hard drive that's split into 3 partitions for backup; one for entertainment, one for work and one for personal projects. A friend of mine had a Lenovo laptop that was having challenges with installing WLAN drivers (you'd install the drivers and they'd keep giving an error that drivers aren't working. If you tried to uninstall them, they'd just reappear...but that's a whole different story). Anyway, my friend decided to roll-back from Windows 10 to Windows 8 and wanted to copy one of the test builds from my 2TB HDD so I lent it to him. Little did I know that that Lenovo laptop had other plans for me. Upon connecting the external hard drive to the Lenovo laptop, it immediately read it as a FAT32 formatted drive (it was actually NTFS formatted) and had 1.82 TB free space of the "actual" size 1.82 TB. Where panic would have ensued for many, I managed to keep in the growing irritation at such a thing ...
