Dealing with Legacy Applications, Random Stuff, and More

- this post is to help outline some methods for dealing with legacy applications...
- compatibility mode works for a lot of programs but sometimes you don't have a choice but other means
- emulation layers such as Wine, Bochs, DosBox, etc... There has even been talk of emulators for older operating systems (such as DOS and Windows 95/98) out there
- watch for strangeness when using emulation layers. Performance issues, bits and pieces not quite fitting in, etc... Be prepared to have to do some work to make things work properly. Some of the underlying programs can be difficult to use so look out for shell, optimisation type programs and templates...

- try running things in a separate virtual machine
- try running things in a seperate server
- some programs re-used backend data to create a new frontend. Total number of applications that have this done is minimal though. The total number of people who can genuinely reverse engineer binary (even text) file formats and programs out there is relatively small based on what I've seen. Tips on this elsewhere on my blog...

- if you're lucky you search for newer version that is still compatible with your operating system. The best way to achieve this is via basic web search. Thankfully, a lot of older/legacy software allows for re-use of serials along the chain

- if that fails look at P2P locations for file names, etc... Worry about the legitimacy of P2P sites because they may be carrying trojans and/or spyware. If it's your last resort use something like virustotal.com as a bare minimum

- else, you may need to build a custom 'fuzzer'. Conceptually, looking for 200 as opposed to 404 return status. Experience tells me that for the most part file fuzzing is a useless technique especially when the company is 'larger then average'. Larger then average entails more files which entails unique filenames and directory structures which can not be easily guesstimated which means a fuzzer is relatively useless. It needs to be an intelligent fuzzer which combines spidering/crawling capability whenever possible (look over my past work for further details). For anyone just looking to try/test new software before public release this is a nice way of doing it. Sample code is on my website and blog for anyone who's interested (look for crawling and spidering software samples as well)...

- you'll need to keep up with updates and services packs for a lot of Microsoft (and some other company's) software even if it may be 'legacy software'. The painful thing is that the updates often only become security updates later on which means you'll lose functional updates down the line at some point. This generally applies to both commercial as well as Free and Open Source (FOSS) software

- look for alternate/compatible solutions. For instance Delphi and Open Pascal/Lazarus are very cross compatible based on what I've read online. alternativeto.net is a great website to look at alternate choices

- nightmare scenario is when you have the license but have lost the serial number. Thankfully, prior to the world of authentication a lot of software was reliant on pure serial numbers for 'registration' and to move a product from trial to full . In fact, there were serial databases for programs online (such as Serials2K). For those programs whose serials can't be found in such databases they can often be found online. Sometimes, there are methods to extract the code that you used to install your software originally (from the Windows registry or some other file) but this often requires a specialised utility

- for certain software you don't really have a choice but to deal with crackers since activation/registration systems are no longer online. Multiple types of bypassing: debuggers, crackers (similar to the devices that you see in the movies that are used to bypass physical security systems. See my book on 'Cloud and Internet Security' for further details regarding this), etc... I may supply code for a simplistic 'cracker' later on but fundamentally it's not that much different then some of the 'bot code' that I have mentioned elsewhere on my blog (it will be so rudimentary that it will be effectively useless. Most modern registration systems rely on activation schemes now or else multi layers of serial numbers which are unrealistic to crack for most people without some 'genuine hard work')

- there are obviously interesting methods to protect/defend software against licensing/registration 'attacks'. Activation is obvious but I've often seen cases where they've had no choice but to drop it because it caused more problems then it fixed
visual studio 2005 activation crack
1. Check license repeatedly
2. Use multiple licensing checking layers
3. Use encrypted dlls
4. Check for the hash of your exe/dll to detect tampering
5. Do not display failures immediately
6. Don't use explicit error messages
7. Crash or fail or output incorrect results when license check fails
8. Embed user information in generated licenses
- go after newer downloads that are compatible with your files and Operating System. Like I said you can do a search, use/build a custom fuzzer, etc... you should be able to find something useful especially if the program registration system is still compatible with your version. Note, Multi-National and Trans-national companies (MNC/TNC) have this problem as well as smaller firms (they rarely ever look to see whether a user has been authenticated prior to allowing downloads)...

- company mergers aren't necessarily a bad thing. Most of the time they just change domains but not file naming and directory structure when they 'switch servers'
- if you can't actually get a copy of the legacy software in question online then try op-shops, specialist software boutiques, retailers, libraries, user/enthusiast groups, organisations which are likely to have a 'spare legacy copy', etc... If not too difficult then try building something from the outset by yourself that is compatible (requires 'reverse engineering' skills though as mentioned above)

- as an aside, if you've worked in this are you'll realise that there is basically no such as thing as genuine 'computer security'. There's only more and less security? It's much easier to attack then defend. When someone tells you that they can break into a system it's not much a statement if you understand the defender's perspective. Most of the people you see/hear about (even professionals) aren't genuine 'security experts' in the way that the average person is taught. Listen to a lot of their debates and lectures and it becomes obvious that a lot of their work is not that much different from a variation from a lot of the scripts that I use on this blog/website?

Random Quotes:
- Pogue claims the report also shatters another common perception of cyber security, “that of the teenage hacker living in a basement”.

The report found that three-quarters of respondents were college graduates and nearly one-third (32%) had post-graduate degrees. The majority (57%) worked for medium-sized, large, or enterprise businesses.

“When organisations develop their cyber security strategies, they may have IT, legal, risk, and human resources teams at the table but the one person they never invite is the bad guy,” Pogue said. “It’s no wonder that so many security strategies are misdirected.

“The Nuix Black Report 2018 is an opportunity to bring the adversary to the table and have the hackers themselves tell you what’s most effective for your security efforts.”
- These results suggest the Iron Dome debate has been too polarized. The system’s initial value may have been largely symbolic. But it later become very influential.

That’s good news for Israel and its American funder. It’s also reassuring for potential Iron Dome buyers facing missile threats in other parts of the world.

Only Azerbaijan has purchased any systems so far. But the U.S. Army may buy some for short-range air defence. (Canada only bought the radar.)

However, the system isn’t “the end of rockets.” Attackers can counter interceptors by firing rockets in large batches. Indeed, Israel’s opponents keep acquiring more rockets. Hamas in strife-filled Gaza reportedly has 10,000. Hezbollah in Lebanon has 120,000. That latter arsenal would severely strain Israeli interceptors during any future “Northern War.”

Similarly, sophisticated attackers use technology to make their missiles hard to intercept. In their Syria strike, America and its allies used difficult-to-detect cruise missiles. Defenders can’t intercept what their radars can’t see.

WINEing and DOSing on Linux

I recently picked up some old (but still very enjoyable games even though their graphics mightn't be up to todays standards). These games included RAC Rally Championship (DOS), Theme Hospital (Windows 95), and Rise of Nations (Windows XP). This post will go through the steps required to get them working under Linux. Note, that I'm assuming that you have installation discs for all relevant programs.

FIrst game I tried was  RAC Rally Championship. I consider it to be one of the better rally arcade/simulator games prior to Colin McCrae's Rally and DIRT. To get it running first install, 'Dosbox' (its a DOS-emulator for various different platforms). Startup the 'dosbox' environment from the Linux CLI or via the relevant GUI menu option. Run the following commands. Then run the following series of commands.


- mount c /media/disk -t cdrom (mount your installation disc to C:)
- mount d ~/rally (mount a folder from your Linux home folder called rally to D: to give the installer a place to place its files. Assumes you have already created the folder of course)

- C: (go to root directory C:)
- install.exe (run the installer file. When prompted install it to D:\)
- cd d:\rally (when installation has completed change to the installation directory)
- ral.exe (run the game)

One thing you'll definitely notice is that while the games are still quite enjoyable they'll often feel quite 'eerie'. Imagine existing in the world of 'True Colour' (32-bit and millions of colours) and then suddenly finding yourself being transported to a world where only 256 colours exist.

 
The next game we'll attempt to setup/run is, 'Theme Hospital'. Similar in concept to 'Zoo Tycoon' it has you running running a Hospital, attempting to find a happy medium between healing patients and fulfilling more tangible/financial goals. I discovered that while installation was quite easy (insert the disc, mount it, then run the setup/installation file via 'wine'), getting everything running perfectly wasn't.



First I needed to get DirectX installed. Instructions are available online for this which involves downloading a redistributable installation file from the Microsoft Download Centre. I opted to use the my Tiger Woods 08 DVD to get DirectX the installation file. While the game worked, sound was not functional. Using 'winecfg' indicated that I was getting 'write' errors to the sound device file and testing obviously produced no sound.



I read up online that a lot of others were having issues with the 'PulseAudio' sound daemon. I also read that removing the package/s could result in 'odd' issues with their desktop installation. Like others, I discovered that killing the pulseaudio damon doesn't actually stop it because it respawns by default. Altering the relevant pulse/client.conf file should changed this behaviour whether done to the core configuration in /etc or via a users' local .pulse setup but didn't which indicated there must be another point of configuration as well. I disabled it through the 'Gnome Startup Preferences' menu option/s. At that point, the error/s disappeared but switching between the different sound daemons still didn't produce success (ESound, Pulse, OSS, ALSA) even though I had installed all relevant 'wine to sound daemon' plugins. Finally, I shutdown everything (sound related) except the core 'PulseAudio' daemon and finally the test/game sound seemed to work even though others have indicated that using ALSA seems to be the best/easiest solution.


While the installer for 'Rise of Nations' went well I've experienced many 'known issues'. Among these, having to use both mouse buttons to navigate through the menu system (though the left mouse button seems to work perfectly fine in the actual game itself), having some regular graphical anomalies (this only occurred with Rise of Nations but not when its Rise of Nations - Thrones and Patriots), a temporary black screen or stall on startup (not a real stall. Use the space bar to reach the main menu), and having no sound. Attempted to switch Direct X libraries between builtin/native as directed elsewhere online to get around these issues but switching to native actually caused an exception to occur on startup of the game so I have since gone back to the program defaults. I also believe that some of these problems may also be version related so I'll update at a later time.



As an inside, I recently scratched one of my game software discs (the game would only run through the install process part of the way before succuming to read errors) but had run out of disc repair solution. I've since discovered that 'toothpaste' actually works quite well as a repair agent since its a light/mild abrasive. It tends to blends the scratch in with its surrounding rather than polishing the disc though.



I recalled the early days of optical drive technology. There were often (and there still are though less drastic) differences in  error detection/correction quality on different drives (I remember a disc that was completely undearable in one drive but perfectly readable in another). I switched from an onboard OptiArc drive to an external Plextor drive and disc reading seemed to be perfect.

I decided it was time for me to make an ISO backup of the disc (allowed under existing law). While the backup disc can be used to install the program, there are mechanisms which prevent it from being used as a startup/game disc (even via emulation software using just the ISO file). There are obviously ways around this type of detection but its always a game of cat and mouse between those who create copyright protection mechanisms and those who attempt to defeat them.
