π¦The exploit achieves R/W access to the host's physical memory all ios 10 :) β verified by undercode
t.me/iUndercode
π¦This exploit has been tested on the iPhone 7, iOS 10.2 (14C92). To run the exploit against different devices or versions, the symbols must be adjusted.
> The attached archive contains the following directories:
-hostapd-2.6 - A modified version of hostapd utilised in the exploit. This version of hostapd is configured to
support 802.11k RRM, and in particular Neighbor Reports. Moreover, this version of hostapd is
instrumented to add various commands, allowing injection and reception of crafted action frames
used throughout the exploit.
-OneRing - The exploit itself.
π¦To run the exploit, you must execute the following steps:
-Connect (and enable) a SoftMAC Wi-Fi dongle to your machine (such as the TL-WN722N)
-Compile the provided version of hostapd
-Modify the "interface" setting under "hostapd-2.6/hostapd/hostapd.conf" to match your interface's name
-Configure the following settings under "OneRing/rrm_exploit/conf.py":
-HOSTAPD_DIR - The directory of the hostapd binary compiled above
-TARGET_MAC - The MAC address of the device being exploited
-AP_MAC - The MAC address of your wireless dongle
-INTERFACE - The name of the wireless dongle's interface
-Configure the following settings under "OneRing/conf.py":
-TARGET_MAC - The MAC address of the device being exploited
-TARGET_IP - The IP address of the device being exploited
-Assemble the backdoor shellcode by running "OneRing/rrm_exploit/assemble_backdoor.sh"
-Assemble each of the code chunks under "OneRing/code_chunks" by running "compile.sh"
-Run hostapd with the configuration file provided above, broadcasting a Wi-Fi network ("test80211k")
-Connect the target device to the network
-Run "OneRing/attack.py"
π¦Following the steps above should result in DART's descriptor being mapped into IO-Space, allowing R/W access to the host's physical memory. You can utilise this R/W access by calling the "read_host_dword" and "write_host_dword" functions, respectively.

π¦ How to modify *.exe files :
learn how to change *.exe files, in 5 easy steps:
1) Don't try to modify a prog by editing his source in a dissasembler.Why?
Cause that's for programmers and assembly experts only.
try to view it in hex you'll only get tons of crap you don't understand.
First off, you need Resource Hacker(last version). It's a resource editor-
very easy to use, You can download it at h**p://www.users.on.net/johnson/resourcehacker/
2) Unzip the archive, and run ResHacker.exe. You can check out the help file too
3) You will see that the interface is simple and clean. Go to the menu FileOpen or press Ctrl+O to open a file. Browse your way to the file you would like to edit. You can edit *.exe, *.dll, *.ocx, *.scr and *.cpl files, but this tutorial is to teach you how to edit *.exe files, so open one.
4) In the left side of the screen a list of sections will appear.
The most common sections are
-String table;
-RCData;
-Dialog;
-Cursor group;
-Bitmap;
-WAV.
*Icon: You can wiew and change the icon(s) of the program by double-clicking the icon section,chossing the icon, right-clicking on it an pressing "replace resource". After that you can choose the icon you want to replace the original with.
*String table: a bunch of crap, useful sometimes, basic programming knowladge needed.
*RCData: Here the real hacking begins. Modify window titles, buttons, text, and lots more!
*Dialog:Here you can modify the messages or dialogs that appear in a program. Don't forget to press "Compile" when you're done!
*Cursor group: Change the mouse cursors used in the program just like you would change the icon.
*Bitmap: View or change images in the programs easy!
*WAV:Change the sounds in the prog. with your own.
5) In the RCData,Dialog,Menu and String table sections you can do a lot of changes. You can modify or translate the text change links, change buttons, etc.
TIP: To change a window title, search for something like: CAPTION "edit this".
TIP: After all operations press the "Compile Script" button, and when you're done editing save, your work @ FileSave(Save as).
TIP: When you save a file,the original file will be backed up by default and renamed to Name_original and the saved file will have the normal name of the changed prog.
TIP: Sometimes you may get a message like: "This program has a non-standard resource layout... it has probably been compressed with an .EXE compressor." That means that Resource Hacker can't modify it because of it's structure.

π¦Configuring your Bulletproof FTP Server Tutorial
I am not sure where I found this tutorial, Itβs been a whileβ¦It might even have been here... ..So if it is one of yours, my hat goes off to you once again....
After reading the excellent tutorial on "Creating an FTP" that Norway postedβ¦
(I would suggest reading and following his tutorial first, then following up with this one)
I thought that perhaps this tutorial might be pretty helpful for those interested in knowing how to configure their Bulletproof FTP Server that don't already know how... Here's how to get startedβ¦
This is for the BulletProof FTP Server 2.10. However, It should work fine on most following versions as well.
I'm assuming you have it installed and cracked.
Basics
1. Start the program.
2. Click on Setup > Main > General from the pull-down menu.
3. Enter your server name into the 'Server Name' box. Under Connection set the βMax number of users" to any number. This is the limit as to how many users can be on your sever at any time.
4. Click on the 'options' tab of that same panel (on the side)
5. Look at the bottom, under IP Options. Put a check in the box βRefuse Multiple Connections from the same IPβ. This will prevent one person from blocking your FTP to others.
6. Also put a check in the 'Blocked Banned IP (instead of notifying client). VERY IMPORTANT! If somebody decides to 'Hammer' (attempt to login numerous times VERY quickly) your server/computer may CRASH if you don't enable this.
7. Click on the 'advanced' tab
8. At the bottom again look at the 'hammering area'
9. Enable 'anti-hammer' and 'do not reply to people hammering' Set it for the following: Block IP 120 min if 5 connections in 60 sec. You can set this at whatever you want to but that is pretty much a standard Click 'OK'
Adding Users
11. Setup > User accounts form pull-down.
12. Right click in the empty 'User Accounts' area on the right: choose 'Add'
13. Enter account name. (ie: logon name)
14. In the 'Access rights' box right click: choose βAddβ.
15. Browse until you find the directory (folder) you want to share. In the right column you will see a bunch of checkboxes. Put a check in the following ones: Read, Write, Append, Make, List, and +Subdirs. Press 'select'.
16. Enter a password for your new FTP account.
17. Click on 'Miscellaneous' in the left column. Make sure 'Enable Account' is selected. Enable 'Max Number of Users' set it at a number other than zero. 1 for a personal account and more that one for a group account. Enable 'Max. no. of connects per IP' set it at 1
18. Under 'Files' enable 'show relative path' this is a security issue. A FTP client will now not be able to see the ENTIRE path of the FTP. It will only see the path from the main directory. Hide hidden flies as well.
Put a tick in both of these.
Advanced:
You don't need to do any of this stuff, but It will help tweak your server and help you maintain order on it. All of the following will be broken down into small little areas that will tell you how to do one thing at a time.
Changing the Port
The default port is always 21, but you can change this. Many ISPs will routinely do a scan of its own users to find a ftp server, also when people scan for pubs they may scan your IP, thus finding your ftp server. If you do decide to change it many suggest that you make the port over 10,000.
1. Setup > Main > General
2. In the 'Connection' Area is a setting labeled 'Listen on Port Number:'
3. Make it any number you want. That will be your port number.
4. Click 'OK'
Making an 'Upload Only' or 'Download Only' ftp server.
This is for the entire SERVER, not just a user.
1. Setup > Main > Advanced
2. In the advanced window you will have the following options: uploads and downloads, downloads only, and uploads only. By default upload and download will be checked. Change it to whatever you want.
3. Click 'OKβ
While you are running your server, usually you will end up spending more time at your computer than you normally do. Don't be afraid to ban IP's. Remember, on your FTP you do as you want.

π¦Create One-Click Shutdown and Reboot Shortcuts windows :
1)First, create a shortcut on your desktop by right-clicking on the desktop, choosing New, and then choosing Shortcut. The Create Shortcut Wizard appears. In the box asking for the location of the shortcut, type shutdown. After you create the shortcut, double-clicking on it will shut down your PC.
2)But you can do much more with a shutdown shortcut than merely shut down your PC. You can add any combination of several switches to do extra duty, like this:
shutdown -r -t 01 -c "Rebooting your PC"
3)Double-clicking on that shortcut will reboot your PC after a one-second delay and display the message "Rebooting your PC." The shutdown command includes a variety of switches you can use to customize it. Table 1-3 lists all of them and describes their use.
I use this technique to create two shutdown shortcuts on my desktopβone for turning off my PC, and one for rebooting. Here are the ones I use:
shutdown -s -t 03 -c "Bye Bye m8!"
shutdown -r -t 03 -c "Ill be back m8 ;)!"
Switch
What it does
-s
Shuts down the PC.
-l
Logs off the current user.
-t nn
Indicates the duration of delay, in seconds, before performing the action.
-c "messagetext"
Displays a message in the System Shutdown window. A maximum of 127 characters can be used. The message must be enclosed in quotation marks.
-f
Forces any running applications to shut down.
-r
Reboots the PC.

π¦Data Capacity of CDs
Abstract
You can fit on a S/VCD without overburning:
- approx. 735 MB of MPEG data onto a 74min/650MB disc
- approx. 795 MB of MPEG data onto an 80min/700MB disc
You can fit on a CD-ROM without overburning:
- approx. 650 MB of data onto a 74min/650MB disc
- approx. 703 MB of data onto an 80min/700MB disc
----------------------------------------------------------------
π¦Introduction
Let us ignore for now the terms of megabyte for CD capacity and try to understand how the data is stored on a CD.
As well all know, the data is stored digitally as binary data. This means, however the actual information is actually kept on the disc, this information is in the form of "1"s and "0"s. Physically, the information on a CD is as pits on a thin sheet of metal (aluminium).
An a CD-R disc, the data is physically on an organic dye layer which simulates the metal layer on a real pressed CD.
----------------------------------------------------------------
π¦How is the information structured ?
Now, on the CD, the information isn't just organised from beginning to end willy-nilly. Otherwise, it would be really hard to find a useful piece of information on the CD.
Rather, the information is organised in sectors. Consider a sector as like a page in a book. Just like you are able to quickly find something in a book if you know the page number, you can quickly find something on a CD if you know the sector number.
Now, remember that the CD was original made to hold audio data. It was decided, that the CD would would 75 sectors per second of audio. Although I cannot guess where this number comes from, it is quite appropriate for the audio CD. It means that you can "seek" an audio CD accurately to 1/75th of a second -- which is more than enough for consumer purposes.
Now, with this in mind, we can work out the total data capacity of user data for 1 sector.
----------------------------------------------------------------
The total data capacity of user data of 1 sector on a CD
CD audio uses uncompressed PCM stereo audio, 16-bit resolution sampled at 44.1 kHz.
Thus 1 second of audio contains:
16 bits/channel * 2 channels * 44100 samples/second * 1 second
= 1411200 bits
= 176400 bytes
Since there are 75 sectors per second
1 sector
= 176400 bytes / 75
= 2352 bytes
One sector on a CD contains 2352 bytes max.
----------------------------------------------------------------
The concept of different MODES and FORMS of burning
Now, audio CD was well and good, but the medium would become much more useful if you could store other data on the disc as well. This became to be know as CD-ROM of course.
Now, the audio-CD uses the ENTIRE sector for audio data.
However, for CD-ROMs this caused a problem. Simply, CDs and the CD reading mechanisms were not 100% faultless. That is, errors (indeed frequent errors) could be made during the reading. For audio CDs, this does not matter as much as you could simply interpolate from the adjacent audio samples. This will obviously NOT DO for data CDs. A single bit error could lead to a program being unexecutable or ruin an achive file.
Thus, for CD-ROMs, part of each sector is devoted to error correction codes and error detection codes. The CD-R FAQ has the details, but in effect, only 2048 bytes out of a total of 2352 bytes in each sector is available for user data on a data CD.
This burning mode is either MODE1 or MODE2 Form1.
----------------------------------------------------------------
MODE2 Form2 sectors of VCDs and SVCDs
Now, for VCDs and SVCDs, the video tracks do not necessarily require the robust error correction as normal data on a CD-ROM. However, there is still some overhead per sector that is used for something other than video data (e.g., sync headers).
S/VCDs video tracks are burnt in what is called MODE2 Form2 sectors. In this mode, only 2324 bytes out of a total of 2352 bytes in each sector is available for user data.
This is MUCH MORE than for CD-ROMs, but still less per sector than audio CD.

- approx. 735 MB of MPEG data onto a 74min/650MB disc
- approx. 795 MB of MPEG data onto an 80min/700MB disc
You can fit on a CD-ROM without overburning:
- approx. 650 MB of data onto a 74min/650MB disc
- approx. 703 MB of data onto an 80min/700MB disc
----------------------------------------------------------------
π¦Introduction
Let us ignore for now the terms of megabyte for CD capacity and try to understand how the data is stored on a CD.
As well all know, the data is stored digitally as binary data. This means, however the actual information is actually kept on the disc, this information is in the form of "1"s and "0"s. Physically, the information on a CD is as pits on a thin sheet of metal (aluminium).
An a CD-R disc, the data is physically on an organic dye layer which simulates the metal layer on a real pressed CD.
----------------------------------------------------------------
π¦How is the information structured ?
Now, on the CD, the information isn't just organised from beginning to end willy-nilly. Otherwise, it would be really hard to find a useful piece of information on the CD.
Rather, the information is organised in sectors. Consider a sector as like a page in a book. Just like you are able to quickly find something in a book if you know the page number, you can quickly find something on a CD if you know the sector number.
Now, remember that the CD was original made to hold audio data. It was decided, that the CD would would 75 sectors per second of audio. Although I cannot guess where this number comes from, it is quite appropriate for the audio CD. It means that you can "seek" an audio CD accurately to 1/75th of a second -- which is more than enough for consumer purposes.
Now, with this in mind, we can work out the total data capacity of user data for 1 sector.
----------------------------------------------------------------
The total data capacity of user data of 1 sector on a CD
CD audio uses uncompressed PCM stereo audio, 16-bit resolution sampled at 44.1 kHz.
Thus 1 second of audio contains:
16 bits/channel * 2 channels * 44100 samples/second * 1 second
= 1411200 bits
= 176400 bytes
Since there are 75 sectors per second
1 sector
= 176400 bytes / 75
= 2352 bytes
One sector on a CD contains 2352 bytes max.
----------------------------------------------------------------
The concept of different MODES and FORMS of burning
Now, audio CD was well and good, but the medium would become much more useful if you could store other data on the disc as well. This became to be know as CD-ROM of course.
Now, the audio-CD uses the ENTIRE sector for audio data.
However, for CD-ROMs this caused a problem. Simply, CDs and the CD reading mechanisms were not 100% faultless. That is, errors (indeed frequent errors) could be made during the reading. For audio CDs, this does not matter as much as you could simply interpolate from the adjacent audio samples. This will obviously NOT DO for data CDs. A single bit error could lead to a program being unexecutable or ruin an achive file.
Thus, for CD-ROMs, part of each sector is devoted to error correction codes and error detection codes. The CD-R FAQ has the details, but in effect, only 2048 bytes out of a total of 2352 bytes in each sector is available for user data on a data CD.
This burning mode is either MODE1 or MODE2 Form1.
----------------------------------------------------------------
MODE2 Form2 sectors of VCDs and SVCDs
Now, for VCDs and SVCDs, the video tracks do not necessarily require the robust error correction as normal data on a CD-ROM. However, there is still some overhead per sector that is used for something other than video data (e.g., sync headers).
S/VCDs video tracks are burnt in what is called MODE2 Form2 sectors. In this mode, only 2324 bytes out of a total of 2352 bytes in each sector is available for user data.
This is MUCH MORE than for CD-ROMs, but still less per sector than audio CD.
----------------------------------------------------------------
The disc capacities of CD-ROMs, audio-CDs and VCDs
Now, obviously what ultimately determines the capacity of a disc is the total number of sectors it contains. This is similar to the total number of pages in a blank exercise book (if you recall the book analogy).
The secondary determinant is the burning mode of the disc.
For audio CDs, it is as if you could fill each page from top to bottom with audio data as the entire sector is used for audio data.
For CD-ROMs, it is as if you need to first rule a margin and then leave the bottom part of each page for footnotes (headers + ECC + EDC). The amount of text you can actually write per page is then less due to these other constraints.
For S/VCDs, we still need to rule a margin on the page, but we don't have to worry about the footnotes (headers). We can fit MORE text than a CD-ROM, but less than an audio-CD.
Now remember, 1 second on a CD = 75 sectors.
Thus:
- 74 min CD = 333,000 sectors
- 80 min CD = 360,000 sectors
Data capacity in Mb for an audio-CD
74 min
= 333,000 sectors * 2352 bytes / sector
= 783216000 bytes
= 746.9 Mb
80 min
= 360,000 sectors * 2352 bytes / sector
= 846720000 bytes
= 807.5 Mb
Data capacity in Mb for a CD-ROM
74 min
= 333,000 sectors * 2048 bytes / sector
= 681984000 bytes
= 650.4 Mb
80 min
= 360,000 sectors * 2048 bytes / sector
= 737280000 bytes
= 703.1 Mb
Data capacity in Mb for a S/VCD
74 min
= 333,000 sectors * 2324 bytes / sector
= 773892000 bytes
= 738.0 Mb
80 min
= 360,000 sectors * 2324 bytes / sector
= 836640000 bytes
= 797.9 Mb

π¦How To Make Your Own Radio Station
b.com/UndercodeTesting
1) Must HAVE Winamp (Any Version)
First, things First your speed has to be at least 256/64 kbps (which means Dial-up users, will have alot of latency, just dnt bother)
Second, your going to have to have a domain, an updated one with the current i.p active. (Could be anything e.g. My sig)
2) Now, Your gonna have to download the Shoutcast Files.
Go to www.shoutcast.com to get the files.
Ok After downloading these, installing Both of them in any order i dnt care. Go to START>PROGRAM FILES>SHOUTcast DNAS>EDIT SHOUTCAST DNS CONFIG.
Ok your gonna have to Configure it:
3) Go Down and where it says password: change (that means your gonna have to change it to whatever, make sure u remember)
4) The Portbase: change it to whatever port you want it
Maxusers: (lets be realistic here, dnt put in 10000, like NXS's radio station) your bandwidth has to be extremely good, if your cable, 50 user max is ok, ADSL should stay below 10 users, and T1 connections should do whatever tickles there fantasy.
5) Open winamp, RIGHT CLICK>OPTIONS>PREFRENCES>DSP EFFECT> and choose the NULLSOFT SHOUTCAST.
6) Go to OUTPUT, and then click on Connection, Through the ADDRESS, type your address which you have done through www.no-ip.com, PORT NUMBER, whatever u did in the EDIT.txt, and your password.
7) Then go to Encoder, and choose your quality of your music. Go back to OUTPU>OUTPUT CONFIG> YELLOW PAGES. this is your advertisemant information. dow hatever you like there.
8) Now Connect. to check that your Radio os on-line go to http://(your address that you added in the prefrence)
