dynamic linkers

• elfling (currently broken)
• bold (currently broken)
• dnload (Linux, FreeBSD)
• smol (glibc Linux, with non-glibc “compatibility mode”)

compressors

• shell dropping: cp $0 /tmp/M;(sed 1d $0|lzcat)>$_;exec $_;
• fishypack: In-memory memfd/execveat-based decompressor (Deprecated in favor of vondehi)
• vondehi: Next-generation in-memory memfd/execveat-based decompressor (See list of known bugs)
• autovndh: script that bruteforces all possible gzip/lzma/xz/… options and automatically places a vondehi decompression stub at the beginning
• oneKpaq: Generic PAQ-based (de)compressor for 32-bit x86

synths

• ghostsyn
• 4klang, ForkedKlang. Note that the replayer code is 32-bit only! You’ll need some hacks to make it work on 64-bit.
• Clinkster, replayer is 32-bit only as well.
• Oidos, replayer is once more 32-bit only.
• Axiom is “supposed” to work

See here for some synth example setup code, together with some Linux-specific patches to get some of the replayers to work.
