@abh1sek @anantshri The crew backstories are what build the character and relate to fans

I read manga and watch the anime and I like this one too

@gynvael constant folding when run with a script I guess, while in the console it creates copies

@MasterMike88 @CodeColorist @SecLists Duke Abbaddon has been on many public security lists spamming like there's no tomorrow

@SpinkaMilan @Mandiant > I have not found a way to convince IDA to use the standard Windows 64-bit calling convention by default, without retyping all functions one by one.

You can change the compiler from "Options > Compiler" afaik for the DLLs in ch9

@S1r1u5_ https://t.co/aITNrJFAxz

it ran shorter(30 days) than last year(45 days) but number of challenges were also 1 less(9 vs 10)

But almost the same

[Moritz @m_r_tz]

Looks like #flareon12 will have similar finisher numbers to last year. #flareon11 had 275 players that solved all levels. With 14 hours left we're at 295 players this year.

[Sudhakar Verma @_sudhackar]

For #flareon12 my intial notes are here for 9, 8, 7 and 5

Currently traveling, but plan to do a full writeup with all thr deobfuscation scripts later in November

Thanks @Mandiant and the orgs @nickharbour @m_r_tz et al. for the great challenges

[Sudhakar Verma @_sudhackar]

@m_r_tz I hope it has all features that LazyIDA https://t.co/HvVfb4NZZg has - which is currently my bridge from ida to a ipython session

[Sudhakar Verma @_sudhackar]

@m_r_tz Had some feedback, please check DMs.

[Sudhakar Verma @_sudhackar]

@ZetaTwo ah sorry, I just grepped the disassembly with capstone

[Sudhakar Verma @_sudhackar]

Finished #flareon12 this weekend
7 and 9 were probably my favorite ones this year

[Sudhakar Verma @_sudhackar]

@ulexec congrats Nacho!

[Sudhakar Verma @_sudhackar]

@nbsriharsha @grok is this info leak?

[Sudhakar Verma @_sudhackar]

@abh1sek @dhanesh_k node-gyp.dll - Is this a compromised artifact from some oss lib?

[Sudhakar Verma @_sudhackar]

@nsg650 sent you a dm!

[Sudhakar Verma @_sudhackar]

@withzombies With the zstd compression support in 9.1 - this would be default on all my machines now.

[Sudhakar Verma @_sudhackar]

@rt10_07 Congratulations on the book!
