v2.1.3

Bug Fixes

• Extract variable sequence in loop (#7): for(let a = (b, c);;) {} -> b; for(let a = c;;) {}

v2.1.2

Bug Fixes

• Operators in comparisons now get properly flipped: 0 < x -> x > 0

v2.1.1

Performance

• Much faster unminifying: 10s instead of 55s on a large script
• max-iterations option got removed, only a single pass is required to achieve the same or better result

v2.1.0

Features

• void 0 to undefined
• undo yoda conditions: if (1 == x) -> if (x == 1)

Bug Fixes

v2.0.0

Features

• Browser version 🎉 https://webcrack.netlify.app/
• String Array Calls Transform can now be deobfuscated

Bug Fixes

• Don't remove unrelated parent node of Self Defending code
• Stricter member expression checks (only matches e.g. require.d instead of require[d])

Breaking Changes

• It can now only be imported as ESM

v1.11.0

Features

• Remove debug protection (freezes the browser if you open devtools)
• Control Flow Flattening can now be deobfuscated when Transform Object Keys is enabled
• Rearrange sequences in variables: var t = (o = null, o); -> o = null; var t = o;

Bug Fixes

• Remove correct nodes in self defending code (based on references instead of the first 2 statements)

Security

• The vm2 package has been updated because of a sandbox escape (should maybe switch to a more secure one like QuickJS). But since we used the allowAsync: false option, it shouldn't be possible to exploit

v1.10.0

Features

• Deobfuscate control flow flattening
• Remove self defending code, domain lock, console disabler
• Remove always false if edge-case

Bug Fixes

• Find correct array rotator if there are multiple

v1.9.1

Performance

• 30% faster string array decoding

Bug Fixes

• also match negative numbers passed to decoder
• rename variable assignments in ESM

v1.9.0

Performance

Deobfuscation and readability transforms are now significantly faster

New Features

Modules can get converted to ESM:

require.r(exports);
require.d(exports, 'Counter', function () {
  return f;
});
class f {}

->

export class Counter {}

This, together with changes to some other webpack functions, will allow unpacked modules to be repacked and run instead of the original bundle:

npx webpack-cli ./webcrack-out
