I am trying to understand how an attacker is able to use the halflm challenge rainbow table to obtain the first 7 characters of a windows password that was used to authenticate a user using LM/NTLMv1. To help you understand my confusion, c… Continue reading Using rainbow tables to obtain the first 7 characters of a windows password(LM/NTLMv1)
There is two different passwords for a single user.
I’m hashing both for future validation. I’m currently using a single unique salt for the user, but each is hashed with a different algorithms (PBKDF2 with different algorithm and differen… Continue reading Is there any benefit to use different salt for different encryption algorithms for same user
I have a top level familiarity with Rainbow tables (1 ,2 )
I also understand that salting adds a randomly generated alphanumeric string to each password before it gets hashed and put in a database.
My understanding of Rainbow tables (RTs) … Continue reading What are the underlying mechanics that make password salting an effective deterrent against Rainbow Tables? [duplicate]
I’ve got a presentation coming up on Thursday, so started prepping. I created rainbow tables lower alpha 1-7 chars, with table index 0-5. I then sorted them with rtsort, and tried to rtmerge. All rtmerge does is copy the files back to /usr… Continue reading rtmerge is not merging my tables [closed]
This is more of a question on the actual use of the terms rather than the definitions, so my question is this:
Are dictionary and rainbow table attacks a type of brute force attack or are they different entirely? Would it be okay to call a… Continue reading Are dictionary and rainbow table attacks a subset of brute force attacks or are they seperate?
Let us imagine a situation where a company stores its user passwords (let’s ignore salts, etc for now) using some hash (say sha256) and the company gets breached. All of the username and password details are now public. The passwords are h… Continue reading Making already hashed wordlists of all possible combinations [duplicate]

I want to create a rainbow table in hashcat to crack a bunch of hashes that I have that are derived from random sequences of 6 letters.
For example, for the string ahdksn, I have the hash bd30537eb320357e3d96d03425cd73f2 in a text file.
I … Continue reading Hashcat Rainbow Table and rtgen [closed]
I try to generate a rainbow table, but nothing found in the current folder:
The filename.rt file should exist but doesn’t
