Forensics: Recovery of Files Ep 2 - Data Rescue PC3

This is the second episode in the Recovery of Files series. Episode 1 has a little more background on the whole aspect of file recovery.

The video below shows a demo of how to recover lost/deleted files using the proprietary tool commonly known as Data Rescue PC3. As in episode 1, in the video, we format the USB drive, add stuff to it, and then format it again in order to recover the deleted files.

Again, just like in episode 1, you will also note that not only the files we lost upon formatting are the ones that are recovered, but this will also include the files from previous drive formats too.

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...

It is not too late to start taking BYOD security seriously

A number of studies have shown that the benefits that come along with a Bring Your Own Device (BYOD) policy are multiple when it comes to improving efficiency of employees. On the basis of these studies, many organizations across the globe proceeded to implement this policy but not all of them managed to carefully consider the impact such a policy would have on the cybersecurity of the organization itself.  With BYOD, you basically allow employees to bring their own devices (such as laptops) to work and connect to the company’s internal network so they can access organizational resources. It also tends to allow said employees to take the devices home and in some cases, get remote access tools installed on the personal devices to allow them to connect to the same internal organizational resources while they are not on site. As you can imagine, the benefits are quite numerous, but as cybersecurity experts, what we naturally tend to look for are weak spots in such policies and h...
