Apple iPhone 5S fingerprint sensor hacked by Germany's Chaos Computer Club

<div dir="ltr" style="text-align: left;" trbidi="on">

Germany's Chaos Computer Club says it has cracked the protection around Apple's fingerprint sensor on its new iPhone 5S, just two days after the device went on sale worldwide.<br />
<br />
In a post on their site, the group says that their biometric hacking team took a fingerprint of the user, photographed from a glass surface, and then created a "fake fingerprint" which could be put onto a thin film and used with a real finger to unlock the phone.<br />
<br />
The claim, which is backed up with a video, will create concerns for businesses which see users intending to use the phone to access corporate accounts. While it requires physical access to the phone, and a clean print of one finger which is one of those used to unlock the phone, it raises the risk of a security breach.<br />
<br />
<br />
Chaos Computer Club shows how it has hacked fingerprint sensor on iPhone 5S<br />
<br />
"This demonstrates – again – that fingerprint biometrics is unsuitable as access control method and should be avoided," said the Chaos Club's blogpost author, "Starbug". "In reality, Apple's sensor has just a higher resolution compared to the sensors so far. So we only needed to ramp up the resolution of our fake. As we have said now for more than years, fingerprints should not be used to secure anything. You leave them everywhere, and it is far too easy to make fake fingers out of lifted prints."<br />
<br />
The group does not claim to have extracted the fingerprint representation from the phone itself, where Apple says it is held on a secure chip. Instead it relies on capturing a high-quality fingerprint elsewhere, and having access to the phone.<br />
<br />
"Relying on your fingerprints to secure a device may be okay for casual security – but you shouldn't depend upon it if you have sensitive data you wish to protect," commented security specialist Graham Cluley.<br />
<br />
Apple did not respond to a request for comment on the hack.<br />
<br />
The revelation is the third security failing discovered since the phone and its iOS 7 software were released last week. First, a hacker found that they could use a flaw in iOS 7's Control Centre feature on the iPhone 4S and 5 to access photos and send emails. Another found that the Emergency Call screen can be used to place a call to any number.<br />
<br />
The Chaos Club details its methods for the fingerprint hack, which begins with a high-quality fingerprint lifted from a glass, doorknob or glossy surface. The print, which essentially consists of fat and sweat, is made visible using graphite powder or a component of superglue, and then photographed at high resolution to create a 2400 pixel-per-inch scan. That is then printed onto an overhead projector plastic slide using a laser print, forming a relief. That is then covered with wood glue, cut and attached to a real finger.<br />
<br />
Apple introduced Touch ID, as it calls the fingerprint system, on its top-end iPhone 5S, unveiled earlier in the month. The technology uses a scanner built into the home button of the phone to take a high-resolution image from small sections of the fingerprint from the sub-epidermal layers of the skin. Apple says "Touch ID then intelligently analyses this information with a remarkable degree of detail and precision."<br />
<br />
Users can choose to use up to five fingerprints - which can be changed - to unlock the phone and optionally pay for iTunes Store purchases. They have first to create a passcode of at least four digits, and then "enrol" fingerprints separately. Apple says that the process creates a mathematical representation of the fingerprint representation, and that it is only stored on the phone.<br />
<br />
Apple's own notes about its Touch ID system on its site say that Touch ID will incrementally add new sections of your fingerprint to your enrolled fingerprint data to improve matching accuracy over time. Touch ID uses all of this to provide an accurate match and a very high level of security."<br />
<br />
The company says that "Every fingerprint is unique, so it is rare that even a small section of two separate fingerprints are alike enough to register as a match for Touch ID. The probability of this happening is 1 in 50,000 for one enrolled finger. This is much better than the 1 in 10,000 odds of guessing a typical 4-digit passcode. Although some passcodes, like "1234", may be more easily guessed, there is no such thing as an easily guessable fingerprint pattern."<br />
<br />
It notes that after five unsuccessful attempts to match the fingerprint, the user has to enter their passcode, and the fingerprint unlock will not work.<br />
<br />
Speaking to BusinessWeek just after the iPhone 5S was unveiled, Craig Federighi, Apple's head of software, emphasised that the fingerprints would not leave the phone. He said that making a finger unlocking and purchasing system "sounds like a simple idea, but how many places could that become a bad idea because you failed to execute on it? We thought, 'Well, one place where that could be a bad idea is somebody who writes a malicious app, somebody who breaks into your phone, starts capturing your fingerprint. What are they doing with that? Can they reuse that in some other location? Can they use it to spoof their way into other people's phones?'"<br />
<br />
He said that Apple's focus had been to make sure that "no matter if you took ownership of the whole device and ran whatever code you wanted on the main processor [you]could not get that fingerprint out of there. Literally, the physical lines of communication in and out of the chip would not permit that ever to escape."</div>

How to Backtracking EMAIL Messages

<div dir="ltr" style="text-align: left;" trbidi="on">
<br />
<br />
Ask most people how they determine who sent them an email message and the response is almost universally, "By the From line." Unfortunately this symptomatic of the current confusion among internet users as to where particular messages come from and who is spreading spam and viruses. The "From" header is little more than a courtesy to the person receiving the message. People spreading spam and viruses are rarely courteous. In short, if there is any question about where a particular email message came from the safe bet is to assume the "From" header is forged.<br />
<br />
So how do you determine where a message actually came from? You have to understand how email messages are put together in order to backtrack an email message. SMTP is a text based protocol for transferring messages across the internet. A series of headers are placed in front of the data portion of the message. By examining the headers you can usually backtrack a message to the source network, sometimes the source host. A more detailed essay on reading email headers can be found .<br />
<br />
If you are using Outlook or Outlook Express you can view the headers by right clicking on the message and selecting properties or options.<br />
<br />
Below are listed the headers of an actual spam message I received. I've changed my email address and the name of my server for obvious reasons. I've also double spaced the headers to make them more readable.<br />
<br />

<br />
According to the From header this message is from Maricela Paulson at s359dyxxt@yahoo.com. I could just fire off a message to abuse@yahoo.com, but that would be waste of time. This message didn't come from yahoo's email service.<br />
<br />
The header most likely to be useful in determining the actual source of an email message is the Received header. According to the top-most Received header this message was received from the host 12-218-172-108.client.mchsi.com with the ip address of 21.218.172.108 by my server mailhost.example.com. An important item to consider is at what point in the chain does the email system become untrusted? I consider anything beyond my own email server to be an unreliable source of information. Because this header was generated by my email server it is reasonable for me to accept it at face value.<br />
<br />
The next Received header (which is chronologically the first) shows the remote email server accepting the message from the host 0udjou with the ip 193.12.169.0. Those of you who know anything about IP will realize that that is not a valid host IP address. In addition, any hostname that ends in client.mchsi.com is unlikely to be an authorized email server. This has every sign of being a cracked client system.<br />
<br />
<br />
Here's is where we start digging. By default Windows is somewhat lacking in network diagnostic tools; however, you can use the tools at to do your own checking.<br />

# Enter ? for additional hints on searching ARIN's WHOIS database.<br />
<br />
I can also verify the hostname of the remote server by using nslookup, although in this particular instance, my email server has already provided both the IP address and the hostname.<br />
<br />
davar@nqh9k:[/home/davar] $nslookup 12.218.172.108<br />
<br />
Server: localhost<br />
Address: 127.0.0.1<br />
<br />
Name: 12-218-172-108.client.mchsi.com<br />
Address: 12.218.172.108<br />
<br />
Ok, whois shows that Mediacom Communications owns that netblock and nslookup confirms the address to hostname mapping of the remote server,12-218-172-108.client.mchsi.com. If I preface a www in front of the domain name portion and plug that into my web browser, http://www.mchsi.com, I get Mediacom's web site.<br />
<br />
There are few things more embarrassing to me than firing off an angry message to someone who is supposedly responsible for a problem, and being wrong. By double checking who owns the remote host's IP address using two different tools (whois and nslookup) I minimize the chance of making myself look like an idiot.<br />
<br />
A quick glance at the web site and it appears they are an ISP. Now if I copy the entire message including the headers into a new email message and send it to abuse@mchsi.com with a short message explaining the situation, they may do something about it.<br />
<br />
But what about Maricela Paulson? There really is no way to determine who sent a message, the best you can hope for is to find out what host sent it. Even in the case of a PGP signed messages there is no guarantee that one particular person actually pressed the send button. Obviously determining who the actual sender of an email message is much more involved than reading the From header. Hopefully this example may be of some use to other forum regulars.<br />

10 reasons why PCs crash U must Know

<div dir="ltr" style="text-align: left;" trbidi="on">
<br />
<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">1 Hardware conflict</span></h2>
<br />
The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.<br />
<br />
For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.<br />
<br />
If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:<br />
<br />
* Start-Settings-Control Panel-System-Device Manager.<br />
<br />
Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.<br />
<br />
Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.<br />
<br />
Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).<br />
<br />
When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.<br />
<br />
To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">2 Bad Ram</span></h2>
<br />
Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.<br />
<br />
But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will often crash the machine if the Ram is overworked.<br />
<br />
One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.<br />
<br />
Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble.<br />
<br />
EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmes.<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">3 BIOS settings</span></h2>
<br />
Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access these settings is to press the F2 or delete button during the first few seconds of a boot-up.<br />
<br />
Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what settings to revert to.<br />
<br />
A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.<br />
<br />
Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">4 Hard disk drives</span></h2>
<br />
After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to<br />
<br />
* Start-Programs-Accessories-System Tools-Disk Defragmenter<br />
<br />
This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting, so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.<br />
<br />
The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).<br />
<br />
Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to<br />
<br />
* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.<br />
<br />
Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.<br />
<br />
Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to<br />
<br />
* Start-Programs-Accessories-System Tools-ScanDisk<br />
<br />
Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">5 Fatal OE exceptions and VXD errors</span></h2>
<br />
Fatal OE exception errors and VXD errors are often caused by video card problems.<br />
<br />
These can often be resolved easily by reducing the resolution of the video display. Go to<br />
<br />
* Start-Settings-Control Panel-Display-Settings<br />
<br />
Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For most desktops, high colour 16-bit depth is adequate.<br />
<br />
If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a hardware conflict. Go to<br />
<br />
* Start-Settings-Control Panel-System-Device Manager<br />
<br />
Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue) and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.<br />
<br />
If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you do in case you make things worse.<br />
<br />
The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button. You are searching for a setting that will display a No Conflicts message.<br />
<br />
Another useful way to resolve video problems is to go to<br />
<br />
* Start-Settings-Control Panel-System-Performance-Graphics<br />
<br />
Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a device).<br />
<br />
Look up your video card's manufacturer on the internet and search for the most recent drivers for it.<br />
<br />

<span style="color: red;">6 Viruses</span></h2>
<br />
Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to<br />
<br />
* Start-Settings-Control Panel-Add/Remove Programs<br />
<br />
Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.<br />
<br />
A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.<br />
<br />
An excellent antivirus programme is McAfee VirusScan by Network Associates ( www.nai.com). Another is Norton AntiVirus 2000, made by Symantec ( www.symantec.com).<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">7 Printers</span></h2>
<br />
The action of sending a document to print creates a bigger file, often called a postscript file.<br />
<br />
Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.<br />
<br />
If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">8 Software</span></h2>
<br />
A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.<br />
<br />
The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.<br />
<br />
Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org<br />
<br />
Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.<br />
<br />
Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.<br />
<br />
Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.<br />
<br />
Remember to restore all the BIOS settings back to their former settings following installation.<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">9 Overheating</span></h2>
<br />
Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.<br />
<br />
One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com<br />
<br />
CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.<br />
<br />
<h2 style="text-align: left;">
<span style="color: red;">10 Power supply problems</span></h2>
<br />
With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.<br />
<br />
If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.<br />
<br />
It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.<br />

Remote Desktop Through Company Firewall

<div dir="ltr" style="text-align: left;" trbidi="on">
<br />
Dont wanna take any credit for this as i got this from another forum thought of it as quite informative so pastin it here<br />
<br />
Note this tutorial is collection of tips I gathered from searching the internet and some credit is due to the original authors. None of which I know.<br />
<br />
A lot of people I know love using the Windows Remote Desktop feature at work, however are prevented from connecting to their home computer because of the company firewall. This is because most corporate firewalls block port 3389 which Remote Desktop uses. Most just switch to VNC, however most find it slower than Remote Desktop.<br />
<br />
This quick tutorial shows how (from a fire walled network that blocks port 3389) you can access your home computer using MS Remote Desktop.<br />
<br />
*This tutorial assumes you have or know how to setup and dynamic DNS client if you need one<br />
<br />
*Assumes you know how to setup port forwarding if you need to.<br />
<br />
Because Remote Desktop is using port 3389 by default, it is not possible to go through a firewall. So you can use port 443. Because this port is always open on your companies firewall to allow https. (One would assume )<br />
<br />
At your home PC:<br />
<br />
1) Configure Your pc to allow Remote Connections in your System Properties (windows - Break) tab Remote. Check 'Allow users to connect remote to this computer.<br />
<br />
2) (add users if needed)<br />
<br />
3) According to<br />
CODE<br />
http://support.microsoft.com/default.aspx?scid=kb;en-us;306759]<br />
<br />
In the registry change<br />
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber to 443 (click Decimal radio button first)<br />
<br />
*Configure your firewall to allow traffic through port 443 (If you need to)<br />
<br />
*Configure your route to forward port 443 to your computer (If you need to)<br />
<br />
If you have IIS running you have to change the port number of https. because it is already listening on this port.<br />
C:\WINDOWS\system32\cscript.exe c:\inetpub\adminscripts\adsutil.vbs SET w3svc/1/<br />
SecureBindings ":444:"<br />
<br />
Or just disable IIS Service<br />
<br />
<br />
For your PC at work:<br />
<br />
According to<br />
CODE<br />
http://support.microsoft.com/default.aspx?scid=kb;en-us;304304<br />
<br />
you can just type the port after the IP-Address of your home PC.<br />
<br />
*Or if you have a Dynamic DNS Client such as No-IP or DynDNS you can type in that address.<br />
<br />
Alternatively<br />
You can add the following to the rdp file. (which you can get to click on Save As on the tab General of Remote Desktop Connection)<br />
server port:i:443<br />
<br />
Extra tip: to have access to your clients hard disk on your remote desktop, check Disk Drives on the tab Local Resources of Remote Desktop Connection<br />

How to Email Forge, sends email from anyone

<div dir="ltr" style="text-align: left;" trbidi="on">
<br />
1. Some ISP's block port 25 so it might not work<br />
2. Most likely, you won't be able to see what yer typing<br />
<br />
First of all, you need an SMTP server. These are extremely common and, in fact, I'll provide one for you (mail.hotmail.com). SMTP: Simple Mail Transfer Protocol. This service runs on port 25 (in most cases) and is used to send outgoing email.<br />
<br />
Now, open up the command prompt and telnet to mail.hotmail.com on port 25 (note: to see what you type, type telnet and enter then type in set local_echo):<br />
<br />
<br />
<br />
code:--------------------------------------------------------------------------------<br />
telnet mail.hotmail.com 25<br />
--------------------------------------------------------------------------------<br />
<br />
<br />
When yer connected type in (except what's in between *'s; you chose what will go in the []):<br />
<br />
code:--------------------------------------------------------------------------------<br />
helo<br />
*wait*<br />
mail from:[whoever]@[whoever.com]<br />
*wait*<br />
rcpt to:[whoever]@[whoever.com]<br />
*wait*<br />
data<br />
*wait*<br />
[write]<br />
[whatever you want]<br />
[in]<br />
[as many]<br />
[lines as wished]<br />
.<br />
*wait*<br />
quit<br />
--------------------------------------------------------------------------------<br />
<br />
<br />
Helo is just a handshake with the server. Mail from: is FROM who you want the email to be. rcpt to: is who you want the email to go to. under data is what you want sent. the '.' ends data. quit quits. There! simple isn't it.<br />
