The function in Listing 10.4 is an enhanced version of the function from Listing 10.3. Instead of using direct indexes into the jump table, this implementation uses an additional table that is filled in runtime. This table contains the actual jump table indexes, and the index into that table is handled by the program in order to obtain the correct flow of the code. This enhancement makes this function significantly more unreadable to human reversers, and would also seriously complicate matters for a deobfuscator because it would require some serious data-flow analysis to determine the current value of the index to the array. The original implementation in [Wang] is more focused on preventing static analysis of the code by deobfuscators. The approach chosen in that study is to use pointer aliases as a means of confusing automated deobfuscators. Pointer aliases are simply multiple pointers that point to the same memory location. Aliases significantly complicate any kind of data-flow analysis process c# remove text from pdf How to replace specific word in pdf using itextsharp C# .net ...

Remove extracted from open ... because the analyzer must determine how memory modifications performed through one pointer would affect the data accessed using other pointers that point to the same memory location. In this case, the idea is to create several pointers that point to the array of indexes and have to write to several locations within at several stages. It would be borderline impossible for an automated deobfuscator to predict in advance the state of the array, and without knowing the exact contents of the array it would not be possible to properly analyze the code. In a brief performance comparison I conducted, I measured a huge runtime difference between the original function and the function from Listing 10.4: The obfuscated function from Listing 10.4 was about 3.8 times slower than the original unobfuscated function in Listing 10.2. Scattering 11 copies of the OBFUSCATE macro increased this number to about 12, which means that the heavily obfuscated version runs about 12 times slower than its unobfuscated counterpart! Whether this kind of extreme obfuscation is worth it depends on how concerned you are about your program being reversed, and how concerned you are with the runtime performance of the particular function being obfuscated. Remember that there s usually no reason to obfuscate the entire program, only the parts that are particularly sensitive or important. In this particular situation, I think I would stick to the array-based approach from Listing 10.4 the OBFUSCATE macros wouldn t be worth the huge performance penalty they incur. itextsharp remove text from pdf c# Changing existing text in a PDF using iText – Sampath LK – Medium

Network Interface: wsdlDate.ws.SimpleDate Implementation: wsdlDate.ws.WsdlDateSoapBindingImpl Interface: wsdlDate.ws.SimpleDate Implementation: wsdlDate.ws.WsdlDateSoapBindingStub Hopefully, we need not know and understand all the information. The knowledge of a specific part, corresponding to the genetic information on some disease, is quite relevant in itself. In the future, the aim of an investigation in this field might be to understand the biological programs well enough to create programs that can interfere with existing ones, for example, to specifically stop or replace a defective program. To describe the complexity of the genome challenge, we can follow K.A. Frenkel [Frenkel 1991] and compare genomic data to the data stored on a tape. This tape would be very large and would contain both data and application programs. Most of the content of the tape would be unknown. The information on some particular program or data would be dispersed throughout the tape. Part of the tape may contain no useful information at all. The knowledge we have on the CPU of the computer that could run such programs is ill-defined and continuously evolving. The code itself uses sophisticated self-modifying techniques. The information stored on the tape is a hypothetical reconstruction that results from the study of different cells in different individuals, and may not work for any real living being. The rest of this chapter is organized as follows. First we review several databases used in similar biological applications. We compare the relational and object-oriented data models and then describe our prototype and examples of queries. c# remove text from pdf PDF : Remove content from PDF page.
