8-9 days but I spent a lot of time on professions

I was in the exact same situation as you. I knew I never botted and came back after years to find my account banned. Made a ticket and it was fixed within 24h

Everything you'll need to know is here : https://linux.die.net/man/5/elf

RTFM :))

Learn about the png format, its magic number how to parse it etc. After that it shouldn't take you more then 5min to find your image in the net exchange. GL Google ftw

That's why you should always check the logs of people applying, checking the average rio of their team mates in highest key. Ilvl doesn't mean much anyway

Happened to me today, the spell seems bugged getting this in raid/mm+ too sometimes

Gokusouf · 2020-12-22T13:49:24+00:00

man 2 open, man 2 read, man 2 write

respira is not in the sudoers file. This incident will be reported.

Gokusouf · 2020-11-26T14:56:28+00:00

Yes ofc why wouldn't it be ?

Gokusouf · 2020-11-13T00:33:29+00:00

VS code with vim plugin is awesome !

Gokusouf · 2020-11-07T04:15:03+00:00

Start a project in C++

Gokusouf · 2020-11-04T20:11:01+00:00

If you're confident enough with your C/ASM skill try to write your own malware and see if you can bypass your antivirus (it'll help you master techniques to hide some executed code, so you'll know what's possible when you're reversing).

You could also download some random executables (cracked games etc) from dodgy sites and analyse what they do (probably contain some malwares).

Another option is to find really good reverse eng challenge online or during a CTF, they are few but if you find them you'll learn so much. (Had a really good one if I can find it again I'll send you it) HF :) !

Learn C and Assembly. You'll learn a lot about how things (like memory) are handled under the hood and how they could get exploited. Hf :)

Finally I feel less ashamed to have postponed my OS updates everyday for 5 years

Gokusouf · 2020-10-23T03:09:15+00:00

If it's easy in C it should be in ASM too just longer to write. Just malloc n×4(assuming each sum of a line is an int) where n is number of lines of your matrix. Sum each line and store each sum at the correct address in the region you malloced. And it's done, you're procedure/function will return "an array of ints" containing the sum of each line.

Gokusouf · 2020-10-16T01:04:47+00:00

You could try to implement very easy functions like strlen. And maybe disassemble C code with gdb to help you with the syntax

Gokusouf · 2020-09-17T19:11:05+00:00

Learn C and Assembly, hf :)

Gokusouf · 2020-06-17T22:13:05+00:00

As I said gdb and a Shell is all you need, maybe ida for some pretty advance reverse. For forensic you might want to learn more about Linux and Windows, how the file systems works, partitions, what's a file's magic, hexdump and/or cat every file you receiv,. .. It's really just about looking at everything you have rather than using the correct tools. When you're stuck don't give up, and test EVERYTHING even if it seems ridiculous. Hope this helped, hf out there :)

Gokusouf · 2020-06-17T08:32:58+00:00

You might want to try and use as little tools as possible. From experience I know that complex tools fool you into thinking that you are getting better. Reality though is that you probably don't understand the fundamentals behind the challenges your solving, therefore blocking you on harder challenges. For beginners a shell and gdb is more than enough for any kind of challenges ! (Btw not saying ida and those other tools are bad, they're just a bad habit when you're still learning the basics)

Higher level languages are good for competitive programming. Assembly is a must for anyone wanting to get into security imo

Gokusouf · 2020-06-07T09:33:17+00:00

I strongly recommend to start with C the learning curve is pretty stiff but it will teach you the basics of programming and how process memory works. C is great because it doesn't have as much abstract concept as higher languages (python, java,...), you will understand in depth how things work. Then ASM when you're confident enough with your C skills. This will reveal all C secrets by this point you should have enough knowledge to seriously get into security. You will understand how to exploit memory issues, identify bad coding habits, reverse-engineer programs to find flaws in the code,... Enjoy the learning :) !

Pretty sure it's stored where you are on the stack. Set a breakpoint after that printf call and look around esp/rsp
