Pe obfuscator

Obfuscated code is source or machine code that has been made difficult to understand for humans. Programmers may deliberately obfuscate code to conceal its purpose security through obscurity or its logic to prevent tampering, deter reverse engineering, or as a puzzle or recreational challenge for someone reading the source code. Programs known as obfuscators transform readable code into obfuscated code using various techniques.

Some languages may be more prone to obfuscation than others. Writing and reading obfuscated source code can be a brain teaser for programmers. Types of obfuscations include simple keyword substitution, use or non-use of whitespace to create artistic effects, and self-generating or heavily compressed programs.

Short obfuscated Perl programs may be used in signatures of Perl programmers. It is a C program that when compiled and run will generate the 12 verses of The 12 Days of Christmas.

It contains all the strings required for the poem in an encoded form within the code. A non-winning entry from the same year, the next example illustrates creative use of whitespace; it generates mazes of arbitrary length [9] :. An explanation can be found here. At best, obfuscation merely makes it time-consuming, but not impossible, to reverse engineer a program. A variety of tools exists to perform or assist with code obfuscation.

These include experimental research tools created by academics, hobbyist tools, commercial products written by professionals, and open-source software. There also exist deobfuscation tools that attempt to perform the reverse transformation.

Although the majority of commercial obfuscation solutions work by transforming either program source code [11] [12]or platform-independent bytecode as used by Java [13] and.

Before :. After :. You could do other things to reduce an attacker's ability to disable your software activation system, for example, but in a native-compiled system like Delphi, you can't recreate source code from the binaries. Another answer the accepted one at the moment says exactly this, and someone else pointed out a helpful tool to obfuscate the RTTI information that people might use to gain some insight into the internals of your software.

You could investigate the following hardening techniques to block modification of your system, if that's what you really want:. Self-modifying code, with gating logic that divides critical functions of your code such as software activation, into various levels of inter-operable checksums, and code damage and repair. Debug detection.

Obfuscation and Hiding

You can detect debuggers being used on your software and attempt to block the software from working in this case. Encrypt the PE binary data on disk, and decrypt it either at load time, or just in time before it runs, so that critical assembler code can not be so easily reverse engineered back to assembly language. As others have stated, hackers working on your software do not need to restore the original sources to modify it. They will attempt, if they try it at all, to modify your binaries directly, and will use a detailed and expansive knowledge of assembler language to circumvent things you may wish them not to.

As a whole Delphi does not decompile back, unlike. If people want to rework your work, they can, no matter what, obfuscation or not, heck, some coders write almost naturally obfuscated code having worked with a few. My vote therefore, is shouldnt bother. Unless someone can show me a decompiler for delphi that really works, and produces full sets of compilable, and all delphi where it was originally, I wouldnt worry one drop.

However, pascal syntax does not allow strong obfuscation and JCF even doesn't do it's best well, it's a code formatting tool, not obfuscator! Toggle navigation TitanWolf. Question When and how should I obfuscate my Delphi code?

What should I know about code obfuscation in Delphi? Should I or shouldn't I do it? Before : After :. You could investigate the following hardening techniques to block modification of your system, if that's what you really want: Self-modifying code, with gating logic that divides critical functions of your code such as software activation, into various levels of inter-operable checksums, and code damage and repair.

There's no point obfuscating since the compiler already does that for you. There is no way to re-create the source code from the binary. And components can be distributed in a useful way without having to distribute the source code.

So there usually is no technical reason for distributing the source code. Why would you need to? If people want to rework your work, they can, no matter what, obfuscation or not, heck, some coders write almost naturally obfuscated code having worked with a few My vote therefore, is shouldnt bother.

Hi Anonymous!!! You have not logged in. Public Feeds. Don't miss to join our educational community.Last week, FortiGuard Labs captured a new Thanos ransomware sample.

This ransomware is being popularly advertised on the underground market as a Ransomware-as-a-Service RaaS tool. In this blog we will present the analysis of the captured sample. This malware was written in C C-Sharp.

C is a programming language developed by Microsoft that runs on the. NET Framework. Another powerful tool we use to debug and analyze. Net-related malware is dnSpy. As shown in Figure 2, the source code has been obfuscated. I tried to deobfuscate this sample using de4dotbut the tool detected an unknown obfuscator in the sample and failed to deobfuscate it.

This makes it a little bit tricky for static analysis. Through debugging and analyzing the decompiled code in dnspy, however, we still found a number of switch flags identifying which functionality is enabled.

The variable names have also been obfuscated. We found that this Thanos ransomware sample also used some anti-analysis techniques. The following is the anti-debugging code found in the sample. In the above code, the program is able to detect five conditions. If one of them is true, the malware process will kill itself. These five detections are:. The malware is also able to download the tool ProcessHide from the internet. This tool is used to hide processes from any monitoring tool that uses NtQuerySystemInformation.

This malware can also set some keys related to Windows Defender in the Windows Registry, as follows. This tactic is used to bypass detection by Windows Defender. After setting its keys in the Windows Registry, it can call the following function to run PowerShell in a hidden manner, as well as disable some features of Windows Defender.

The following code is used to set a number of options for MpPreference, which intend to bypass the detection of Windows Defender.Find centralized, trusted content and collaborate around the technologies you use most.
