SELF-MODIFYING CODE. "Self-modifying Brainfuck, also known as SMBF, is a variant of brainfuck by Simon Howard, which allows a program to modify its own source code." https://lnkd.in/dgayvgB View in LinkedIn

AVATAR VEGETATIVE REPRODUCTION. "As a special case of agents constructing successors with equivalent goals, a machine intelligence may wish to change its own source code—self-improve. This can be viewed as constructing a successor agent that shares most of your program code and runs on the same hardware as you, then replacing yourself with that agent." https://lnkd.in/d37SFab View in LinkedIn

DIGITAL AVATAR. "Suppose a sufficiently intelligent agent possesses a goal (or a preference ordering over outcomes, or a utility function over probabilistic outcomes). One possible means for the agent to achieve its goal is to construct another agent that shares the same goal." https://lnkd.in/d37SFab View in LinkedIn

PERFECT PROTECTION. "While hiding the internals of a program can be used to protect the intellectual property contained within or protected by software, it can be applied for less righteous causes as well. Viruses, for example, try to hide their malicious intent through the use of self-modifying code." https://lnkd.in/dzxTmXb View in LinkedIn

SO ENDS this Fragment on symmetry breaking in animals. In many systems in nature, one encounters what at first sight seems like Byzantine complexity on steroids. Whether it is the double fertilization of plants, or animal polarity regulation, it seems to make little sense, and seems duplicative and inefficient. But when you consider that they were designed by chance, often due to the collision of gene systems, scrunched together, asking for elegance is simply the wrong question. View in LinkedIn

LITTLE OPPOSITION. "Polymorphic and metamorphic malware are evolving. Discovery in real-time or postmortem is difficult. Limited resources are applied." https://lnkd.in/ddUukF9 View in LinkedIn

CROSSING SPECIES BARRIERS. "Finally, it is not impossible for a viral species to cross computing platform barriers. A programmer may adapt a pre-existing virus for a new environment.” https://lnkd.in/g5hUBjg View in LinkedIn

ADVANCED POLYMORPHIC ENGINES "generate different instructions which do the same thing; swaps groups of instructions; creates calls to dummy routines; generates lots of conditionals jumps; embeds anti-debugging tricks; inserts junk instructions into real code." https://lnkd.in/d3T75KG View in LinkedIn

CODE BUILDER. "MSIL/Gastropod is a code-builder virus: It reconstructs its own host program with itself. This method allows the virus body to be placed to an unpredictable position within the host program." https://lnkd.in/d_2z5qc View in LinkedIn

DECOMPILING VIRUSES. "Some new MSIL viruses, such as MSIL/Gastropod, already support semi-metamorphic (permutating) code generation under the .NET Framework. Such viruses have a great advantage because they do not need to carry their own source code. Instead, viruses can simply decompile themselves to generate new binaries." https://lnkd.in/d_2z5qc View in LinkedIn
