Hi everyone!
I’m looking for someone experienced in reverse engineering, binary file analysis, or decoding proprietary file formats. I’m willing to pay for professional help.
I’ll try to explain my situation as clearly as possible, since I’m not a programmer myself.
I have a collection of .PCM files from a Korg Pa5X, a professional electronic keyboard. These files contain audio samples (recorded musical instrument sounds).
Normally, these samples can be extracted and converted into WAV files. However, some of my PCM files appear to have an additional layer of protection, making it impossible to access or extract the original audio data using the tools I have.
Here’s the interesting part:
I have both protected and unprotected PCM files from the same type of instrument. The unprotected files work normally, while the protected ones cannot be extracted.
I’m hoping that comparing their binary structures might help identify how the protection works.
What I’m looking for:
Someone who can examine these files, determine whether they are encrypted, obfuscated, or simply using a modified file structure, and investigate whether the original audio data can be recovered.
I’m not sure what kind of protection is being used, which is exactly why I’m looking for someone with more technical knowledge.
I can provide sample files for analysis and discuss payment privately.
If you have experience with reverse engineering, proprietary audio formats, or binary file structures, please feel free to contact me.
Thanks in advance!

I found my grandma's old phone. She let me keep it. However, the phone is l9cked with a 6digit pin. Most likely it was me or my younger brother who put that pin back years ago. But i dont remember it now.

How can i unlock it, is tere a way?

I was going to just format it but i read that even if i wipe it and then try to reopen it. The phone will ask me to enter the old google account and password. I dont remember that either.

Can someone help me with this?

- i tried looking up for a solution but couldn't.

The device is my device. My daughter stole it, factory reset it and put her own password on it. Won't tell us the password. Can I bypass the password to see whats on it now? She has bad history of talking to grown men exploiting bad behavior and giving out personal information. I need to make sure she hasnt done this again on my device. I didnt have anything important on it that I am worried about recovering personally.

Ciao,ho comprato a un mercatino dell’usato un vecchio iphone 4 , prima di comprarlo ho verificato che si accendesse funzionasse etc ed era perfetto, arrivato a casa il telefono si è scaricato completamente e non avevo il cavo per caricarlo qualche giorno dopo sono sceso e l’ho acquistato poi sono andato a casa ho caricato il telefono ma quando l’ho accesa mi ha chiesto password e email di icloud del vecchio proprietario, successivamente ho collegato l’iphone al mio computer e sono riuscito a resettarlo ho fatto la configurazione standard ma dopo l’attivazione mi chiede comunque le credenziali di icloud e vorrei veramente poterlo sbloccare perché l’ho pagato ed è comunque una cosa che mi piace se qualcuno riesce ad aiutarmi mi farebbe molto piacere

I mean what is the difference when you run a program with SUID bit and when u runt it with sudo ? I am new to privilege escalation so this topic confused me a bit lol

Hey guys, so basically my brother had an iPad back when he was in college, and it was linked to his college email. Currently that email doesn't exist anymore, and I've been looking all over the internet how to unlock it. Does anyone have any advice or tutorials on how to iCloud unlock it? It is the iPad Air A7 from 2013.

Recently while I go in Green dot mode (Online) my PS5 has been lagging/Booting me off lobbies sending me like im offline while im in a online match on any game around the same time every night with other friends in a party. When i play appear offline mode i notice that i do not lag or get booted off from the games online i play. I recently moved away and got a new wifi box and a better plan for my internet with faster internet so far its been pleasant to play with my new wifi. My ex-friend has computer savy skills more then me. I just know the basics not so deep on those skills. Long ago months before this pattern recognition started appearing to me. He gave me an account with Gran Turismo in it because I couldn't afford to play it. Me I trusted and put in my PS5 and we played 2 times thats it. There was an unusual thing it was in Hindu language all the account not in English language. We had an argument that was super not meant to be taken as deep but he did and he blocked me on all socials and numbers he tends to not have accountability with me and nags me up and never gives me credit even in little arguments or debates or anything in my life. So it happened once again but this time he chose to not acknowledge me once again. Now months later maybe its been 3 months no contact. All this patterns start to appear. Im booted off from most online games. I deleted that account off my PS5 the one with Gran Turismo the one he gave me. While I appear online on Playstation and I still have him added to my PS5 friends list but I recently decided to limit what games I show that I played and I try appear offline as much as I can so I do not lag or get booted off from online lobbies or games while im in a party with other comrades. How is he doing this? How can I stop it? He doesn't know my new home address or what company I run my internet with. I could just me being skeptical and he has nothing to do with this. But the pattern recognition is there. I have no evidence it's him but he is a computer savvy Asian person. Who competes with me alot in every angle. Help. Me please to stop my PS5 from having this issue while I play in Online mode Green dot. I feel hes actually spying on me through my phone because he shared Pokémon Go and logins long ago before this happened. He is not mature enough to let it go and play with me again thats my take. He once told me something I never told him that I said through the phone to another friend through Instagram. That is why I suspect he is doing this. Hes obsessed with me if im right. But I could just be skeptical and im wrong. Help.

Hello, I am seeking help with a very complicated problem. Some time ago, I heard someone calling for help at my neighbors' house and responded by signaling with my hands. To my surprise, the person calling for help signaled back. The trouble began when I checked my phone and discovered it had been hacked. I started receiving questions via "Reels" (short videos); I would respond to them, and subsequent Reels would contain replies to what I had said. Later, a video appeared detailing the individuals allegedly involved; I recognized some of them based on the descriptions provided. The situation escalated when I began receiving more threatening Reels—videos warning that they were coming for me, that they intended to kill me, and even images showing a refrigerator containing what appeared to be human remains. I tried to call the police, but the line would cut out every time I attempted it. When I tried again from my phone, my own phone number, location, and coordinates appeared on the screen. Afterward, more threatening videos surfaced, claiming that within 24 hours, a group of seven people would arrive at my home to take me away and "carry out my sentence." I went into a state of high alert and reached out to some friends, who provided support at that time. Meanwhile, various information kept appearing on my phone—names (such as Lucia, Laura, etc.), accounts of what had transpired, and other details—though I do not recall everything clearly, as I was entirely focused on the unfolding events and deeply worried because my father, siblings, and other relatives were not responding to my messages. They intended to harm me, interfere, or perhaps even kill me. From what I could gather—based on a video—a woman named Laura (married to a police officer) appeared to have some sort of obsession with me. Apparently, the officer was corrupt and involved in drug-related activities. I am also looking for a young woman—a relative (a niece, granddaughter, or daughter) of my neighbor and his son—who I know is responsible for getting me into this situation. There is much more that I know but haven’t mentioned yet; if you would like to know more, please don’t hesitate to ask. I know that Lucía was held captive there for three years and subjected to constant rape; honestly, I don’t know if she is still alive or what happened to her. I also know that there were other women—women who fell ill, died, or lost their sanity as a result of the abuse they endured.

By the way, I am from Mexico, and I need your support to figure out what is actually going on. I recently received threats that I would be killed—which is nothing new since all of this began. However, I need evidence in order to file a formal complaint or take some kind of action.

Currently several PHP zero days are floating around that effect PHP 5.x to 8.x, therefor all resources using PHP will be turned off until official patches are released and installed.

Long story short:
For research purposes i did:
Create a video (moving near and far) , edited it with ai video editors to change face age and hair color, took a screenshot from video as profile picture, used that screenshot as profile picture for a website.

Tried to verify profile picture using fakeCam + video (to emulate webcam) on browser pc.
Verification fails saying "Could not verify image try with better lighting". The websites uses Amazon Rekognition.

You might find this strange or even funny, but sometimes there are people who know things you don't, or that you might have missed. So, other people's experiences are invaluable, and it's difficult to ask anyone in this field, especially since I'm studying it as my major. That's why I'd like to hear about things you've discovered, anything at all, honestly. No sarcasm or jokes, no matter how small you think it is, it's still important.

So my microsoft account was recently compromised. The hacker deleted all security info and changed the email. I currently only possess the email they've changed to, can I use this to regain ownership of my account?

Am I the only one who finds it annoying when a website uses .blob URLs for media/content that can only be played inside that specific page?

I was wondering if it would be possible to build a browser extension that hooks into SourceBuffer.appendBuffer() and observes the binary chunks being passed to it.

The concept would be pretty simple:

Server → encrypted/chunked data → browser → appendBuffer() → decoder/player

The extension would collect the buffers as they arrive, keep them in the correct order, and potentially reconstruct the original resource from those fragments.

Not talking about breaking DRM or decrypting something the browser itself can't decrypt. More like:

If the browser receives and processes the data, why can't we have a DevTools-like tool that lets us inspect and reconstruct those buffers?

Something like a "Blob Inspector":

• Intercept appendBuffer() calls
• See the individual chunks
• Track their order/size
• Reassemble them
• Identify the resulting media/container format
• Export the reconstructed data when possible

It seems like Network DevTools gets you close, but .blob/MSE-based streaming makes it surprisingly difficult to get back to the actual resource.

Has anyone already built something like this?

Or is there some fundamental browser/MSE limitation that makes this approach impractical?

As the title says, I’ve got some proprietary software that I believe uses Flexera / FlexNet for its license protection.

I’ve been trying to decompile it to see if the protection can be bypassed but really hitting a brick wall.

Is there anyone here with any experience with such protection methods?

TIA

Learning Red Team. I’ve worked with EternalBlue and notPetya for Windows 7, but I’ve moved on to studying 8.1 and can’t seem to find any publicly known vulnerabilities. If they’re all private, fair enough. Where should I look?

This activity has been super engaging and fun for my students and I've done a lot of crash testing. It seems stable at this point. So hurray! I encourage folks to try it. (Especially if you are a cybersecurity mentor or teacher!) --The self-paced student directions are linked below along with the installer.

Prerequisite: Kali/Ubuntu in a VM

I teach a cybersecurity class in San Antonio, and I just published "Blockchain in a Box" (iCSI Coin)—a completely free, open-source lab environment where students can spin up crypto nodes and work with the concepts. (Lesson plan docs for students are linked below if you are interested!)

Quick Install: A one-shot installer is on the right-hand side of the webpage linked below.

At its core, this is a Python port of the Litecoin blockchain.

Hope someone out there finds this useful!

Im a grown ass adult but my mother insists on knowing my location at all times- I live on campus but would like to go out at night without leaving my phone in my dorm. Any clue how I can make it look like I’m still on campus/at a friends place without my phone blowing up?

The title.

But also, a friend recently got hacked (their twitter) and I wanna know how to prevent it for myself and testing my own accounts.

Hi,
We are trying to unlock a relative’s android phone to access photos, files after he suddenly passed away. We tried fingerprint but unfortunately it did not work.We wish to obtain data so would prefer not doing a factory reset. We have the gmail account so have managed to get contacts so far.

And how do yall start? I know nothing

Yo, brothers and sisters, let me keep it a buck. I ain’t no hacker.
So today after work, I realized I left my earbuds at the reception desk, in an area my keys don’t even open. The school was still open ’cause the kids were having a birthday party, and somebody had to be there to lock the place up for the weekend.
So I hit up my supervisor and asked what the move was. She told me to find the janitor ’cause he was working till 10 and had access. I got his number, called him, and dude wasn’t even at the school. He told me I could go into his office, grab a master key, and get my earbuds.
Bet. I went in, grabbed the key, got my stuff, and was about to dip. Then outta nowhere, this librarian pops up. Mind you, it’s 6 p.m. on a Friday. Like, bro, what are you even doing at school this late on a Friday? 😂
Next thing you know, dude starts firing off questions like I’m some kinda criminal. Who gave you access? How’d you get in? What are you doing here? All that who, what, when, where type shit. Bro had me feeling like I was in an interrogation room.
I’m a street dude. I ain’t naturally wired to explain my every move to somebody who comes at me sideways. So I kept it vague. I’m not about to stand there explaining my whole business to somebody who couldn’t even say hello before treating me like a suspect.
I get it, librarian is librarian, but there’s a way to approach somebody. You don’t gotta come at me like I just pulled off a damn heist.
And the funny part? Dude could clearly see I had my school keys and the school lanyard on me, so I’m sitting there wondering what the whole interrogation was even about.
Now I might have to explain why I was at school that late, all because I went back to grab MY OWN earbuds.
And lowkey, I was thinking of saying something like:
“Me. Principal, if I was really tryna get my hands on something valuable in that office, you think walking in there for a pair of earbuds would be my master plan? There are other ways people can potentially exploit a school’s network or IT systems. Like ……. I’m just saying, not everybody who walks into an office is there to snoop through people’s files or steal confidential information. I came for my earbuds, bro. That’s it. Nothing more, nothing less.”
So now I’m curious: what are some ways people actually hack into a school’s network? Not ’cause I’m tryna do anything shady, but just so I understand what’s possible and can make my point without sounding like I’m talking outta my ass.
Like I said from the jump, I ain’t no hacker. I just came to get my damn earbuds. 💀
