Timeframe to mask attack 10 character password

How long would it take to mask attack a 10 character password that includes upper/lower case letters, numbers and special characters and one of the special characters is known (not its place in the password though) using 8 rtx 4090's?

Was given a free pass to a local Cyber Security Summit, anyone here been to one of these? How was it?

Posted on /r/cybersecurity with no response, so figured I'd try here. I was approached online to see if I'd be willing to go to this Cyber Security Summit in Los Angeles late last week and I'm curious if anyone here's been to any of the events hosted by these people. I've been more of a DEF CON / HOPE type of goer, and compared to that this seems far more corporate CTO forward than anything else. Finally, since I've heard it's mostly like a vendor row in a previous post, is there at least some good swag that makes taking the 4:15AM train worth it?

Buffer overflow, canary enabled but program only seems to accept arguments as input

I've got a pretty tricky flag that I have been beating my head against for a while now and would love an explanation for how something like this would be possible. I have a program that when run, seemingly immediately cancels itself. File returns:
file.exe: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=60e0255339eac5de5c216aed54d2b55cfa3d7dda, not stripped
and Checksec returns:
Arch: amd64-64-little RELRO: Partial RELRO Stack: Canary found NX: NX enabled PIE: No PIE (0x400000)
As you can see, it has a canary enabled which is a problem considering the program accepts no input after running it. Usually I would either brute force the canary or grab it when it leaks then pass it to be input, but I don't see how it's possible to grab the leak and then put it in as an arg after the fact - but since the canary changes on execution you clearly have to do that. Everything looks like you'd expect when disassembling it in ghidra - except for the no input part. Here's the main func:
0x000000000040060e <+0: push rbp 0x000000000040060f <+1: mov rbp,rsp 0x0000000000400612 <+4: sub rsp,0x10 0x0000000000400616 <+8: mov DWORD PTR [rbp-0x4],edi 0x0000000000400619 <+11: mov QWORD PTR [rbp-0x10],rsi 0x000000000040061d <+15: mov rax,QWORD PTR [rbp-0x10] 0x0000000000400621 <+19: add rax,0x8 0x0000000000400625 <+23: mov rax,QWORD PTR [rax] 0x0000000000400628 <+26: mov rdi,rax 0x000000000040062b <+29: call 0x4005a7
and here's the evil func:

​
0x00000000004005a7 <+0: push rbp 0x00000000004005a8 <+1: mov rbp,rsp 0x00000000004005ab <+4: sub rsp,0x70 0x00000000004005af <+8: mov QWORD PTR [rbp-0x68],rdi 0x00000000004005b3 <+12: mov rax,QWORD PTR fs:0x28 0x00000000004005bc <+21: mov QWORD PTR [rbp-0x8],rax 0x00000000004005c0 <+25: xor eax,eax 0x00000000004005c2 <+27: mov DWORD PTR [rbp-0x54],0x0 0x00000000004005c9 <+34: mov rdx,QWORD PTR [rbp-0x68] 0x00000000004005cd <+38: lea rax,[rbp-0x50] 0x00000000004005d1 <+42: mov rsi,rdx 0x00000000004005d4 <+45: mov rdi,rax 0x00000000004005d7 <+48: mov eax,0x0 0x00000000004005dc <+53: call 0x4004b0
Any input would be greatly appreciated!

edit: this is what I get when I overflow:
$ ./malicious.exe aaAa0Aa1Aa2Aa3Aa4Aa5Aa6Aa7Aa8Aa9Ab0Ab1Ab2Ab3Ab4Ab5Ab6Ab7Ab8Ab9Ac0Ac1Ac2Ac3Ac4Ac5Ac6Ac7Ac8Ac9Ad0Ad1Ad2Ad3Ad4Ad5Ad6Ad7Ad8Ad9Ae0Ae1Ae2Ae3Ae4Ae5Ae6Ae7Ae8Ae9Af0Af1Af2Af3Af4Af5Af6Af7Af8Af9Ag0Ag1Ag2Ag3Ag4Ag5Ag *** stack smashing detected ***: terminated Aborted (core dumped)

learned alot about hacking. what next?

Learned alot in college but what are the next steps? Do I dualboot kali and mess with the cmd line? Mess with scripts? I know about those websites like hack the box etc. But I want to have a more solid foundation. To build an understanding.

Also. Anyone have any fun project ideas? Maybe cracking a phones screen lock? Or snagging neighbors wifi? Lol jk... ish.

Lemme know your opinions. Ideas or experience!
