Sniffing and Grabbing attachments with Wireshark

This kind of attack only works if the victim/target is using http to connect to their mail server and not https. In this case, the connection is unsecured!

This means we can do packet sniffing without having to do much donkey work. For that, we use Wireshark (which has a great deal of capabilities beyond this alone).

It may seem strange that we’re attacking our own machine in this scenario, but a little more reading on Wireshark will let you know how this will work.

To add to that, for this attack you will also need to have a table of magic numbers at hand because they will be very useful to you.

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...

Malware Analysis: A Python Malware on campus 1

So a few weeks back after a class I'd taken with them, a number of my students told me of a particular malware that was affecting students' computers, in particular, computers running Windows OS. According to them, if you tried to open a folder that was residing on the USB stick with the malware, the malware would delete some of your files and convert folders into executable files. Granted, the likelihood of a random folder miraculously transforming into a single executable file was kinda "out there" but I figured I'd check it out and use that as a teaching moment for those interested in venturing into malware analysis. So I tasked them to bring me a sample of the malware so I could take a look at it and maybe figure it out. I advised one of them to download DumpIt and then extract the memory dump from an infected computer using a clean flash disk and then bring it to me. How do you do this exactly? here's how: Download DumpIt . It's a portable...

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 ...
