“How this proliferation occurred is unclear, but suggests an active market for ‘second hand’ zero-day exploits,” Google's report reads, using the term zero-day to refer to secret hacking techniques that exploit unpatched vulnerabilities. “Beyond these identified exploits, multiple threat actors have now acquired advanced exploitation techniques that can be reused and modified with newly identified vulnerabilities.”
both of these approaches use NFAs under the hood, which means O(m * n) matching. our approach is fundamentally different: we encode lookaround information directly in the automaton via derivatives, which gives us O(n) matching with a small constant. the trade-off is that we restrict lookarounds to a normalized form (?<=R1)R2(?=R3) where R1/R2/R3 themselves don’t contain lookarounds. the oracle-based approaches support more general nesting, but pay for it in the matching loop. one open question i have is how they handle memory for the oracle table - if you read a gigabyte of text, do you keep a gigabyte-sized table in memory for each lookaround in the pattern?
