In one embodiment, a runtime system modifies object code of an executable file to include encoder routines to abstract memory accesses to data in an obfuscated heap. In one embodiment, a compiler system using an intermediate representation of a high level program generates an intermediate ...
Since C#'s internal string representation is UTF16, UTF16 performs better. However, the payload tends to be larger; in UTF8, an ASCII string is one byte, while in UTF16 it is two bytes. Because the difference in size of this payload is so large, UTF8 is set by default....
wmap has two modes of operation. First is "anonymous" memory allocation which has aspects similar to malloc. The real power of wmap comes through the support of "file-backed" mapping. Wait - what does file-backed mapping mean? It means you create a memory representation of a file. Reading...
dumpsys is an Android tool that runs on the device and dumps information about the status of system services and applications. dumpsys enables you to easily access system information. Get system information in a simple string representation. Use dumped CPU, RAM, battery, and storage to check ...
It is a good representation of the actual memory usage of an application. 4. Alternatives to pmap pmap is not the only tool that exists to get detailed information on memory usage. We’ll briefly present other tools in this section. 4.1. Bundled With Linux We can inspect the /proc pseudo...
thejava.lang.String.internmethod returns a string’scanonical representation; the result is a reference to the same class instance that would be returned if that string appeared as a literal. If an application interns a large number of strings, you might need to increase the size of the perma...
* Instances of the MemoryUsage class are usually constructed * by methods that are used to obtain memory usage * information about individual memory pool of the Java virtual machine or * the heap or non-heap memory of the Java virtual machine as a whole. * * A Memory...
Fig. 10. Representation of buffer overflow working on a memory. In Fig. 11, hardware security knowledge is organized by attack method. The left column shows the targets of the attack, and the right side shows the position of the attacker within the supply chain of hardware. Sign in to dow...
Source code can access a string representation of the signature for a given type using__builtin_xnu_type_signature(). For example,struct iovecfrom the beginning of this post would have a signature of "12," meaning the first 8 bytes hold a pointer and the second 8 bytes hold a data valu...
followed immediately by the minimum 16 bytes allocated for the 1-byte request. Just to add visual clarity, the lettermappears in each allocated byte beginning at the address of the allocation. Them's are visible in the ASCII representation of memory to the right of each line. At the end ...
