Using Windows Task Manager, I acquired the Chromium-based browser's process memory and performed hexadecimal and string analysis with WinHex, identifying credential artifacts within the captured memory space. The experiment demonstrates how sensitive authentication data may persist in volatile memory, depending on browser memory allocation, application behavior, and acquisition timing. Memory indeed sits above disk. Key takeaway: TLS encrypts credentials in transit, but it does not eliminate potential plaintext exposure within endpoint memory.
I captured 32 GB of RAM from my Windows system with Belkasoft RAM Capturer. Then I ran WinHex’s File Recovery by Type on the image. The output was multiple file types, each sorted into its own folder. The JPEG folder ran past 004000 files. Three of those faces belong to people I follow on X. @Josephnartey_ @ireteeh @samgeorgegh. I have never interacted with them. WinHex also returned a search hit for X at offset 1ED6721F. A trace of the platform sat in memory next to the images. This is the order of volatility in practice. 𝗥𝗙𝗖 𝟯𝟮𝟮𝟳 tells investigators to collect the most volatile evidence first. Memory sits above disk. RAM holds image data, file fragments, running processes and network connections. A shutdown erases all of it. My rule on every live system, acquire memory, then image the disk, then power down. Skip step one and you cannot get it back.

Not to sound delusional, but please pray for grace. Life isn't really about hard work. It's more about alignment, meeting the right people, grace, mercy, and favour.

Imagine someone accessing your account without knowing your password. That's possible with a stolen session cookie. Cookies aren't malicious. They help websites remember you and keep you logged in. But in the wrong hands, a valid session cookie can become an access key.

The game engine is using actual geographical map data. So when you see Accra, you’re looking at the real Accra, not a fictional city. You can walk around, explore the city, and even fly over it. The character is a bit off 😂 ive been working on this engine for only 18 hours. Give me time
I built a game engine from scratch using c++

Sometimes the best solution to a problem is to close your laptop and go to sleep. You can struggle with something for hours, wake up the next morning, and solve it in five minutes. Your brain really needed that break.

"Came up empty" is a result too, and it belongs in the report: what was searched, with which tool and version, over what data. And "not found" isn't the same as "never existed", so the report should say that too.

1/8 This is a legitimate question. And I don't think that we do our faith any favours, when we dismiss questions like these with religious clichés. As a Christian, I've come to accept that the human mind cannot fully comprehend the operations of God. But let's go further.
I’m confused small “If our God we serve sees and knows everything! I’m sure he sees when we go through very tough times right? He has us at heart too right? So why must we fast and pray to Him that sees and knows everything before our problems can be solved?” I mean he sees it all, and knows deep in our hearts what we need right? Why doesn’t he just do it but demand we pray to him first before he gives us a solution?

I think your argument starts with a wrong assumption. You’re assuming that because God knows about a problem and has the power to solve it, He must solve it immediately. Knowing something, having the ability to change it and choosing when or whether to intervene are 3 different things. You’re also assuming prayer is a requirement God imposes before helping us. Who says God never helps people who don’t pray? If God is all-knowing, then logically, prayer cannot be about giving Him information He doesn’t already have.

If it never reaches the person who has to act, it does not matter. A briefing is not the win. A platform nobody can field is just a better brief.

Networking opened doors. It didn’t close the deal. That took reps, follow-through, and getting comfortable being evaluated. #veteran #militarytransition #networking

Today in HIVE Consult’s Pentest and DFIR Lab, Instructor @elormkdaniel demonstrated how our forensic box can be used during a mobile device investigation. The BlockBox helps isolate a phone or laptop from cellular, Wi‑Fi and Bluetooth signals while investigators handle it. This reduces the risk of incoming messages, remote commands or a remote wipe changing potential evidence. Elorm’s demonstration shows why protecting a device’s state is an essential first step in a mobile investigation. Follow our LinkedIn page: linkedin.com/company/hivesec… Thank you💚

I've watched people treat extension mismatch like the finish line. It's usually just the first flag. The burnout piece is real though. A thousand files and every one wants another look.

Perfect research this how attackers would be able to bypass security due to steganography Research carried out by @aptdaddy and the @hsc_consult has shown that ransomware compromised has used this method in advanced threat simulations leading to complete file encryption
A 1.47 MB JPG caught my attention today. It looked out of place in the folder. I took a look under the hood. Using Steghide, I found an embedded ref.xml file inside the image. To a regular user, it's just a JPG. It can be shared, uploaded, or passed around without anyone realizing they're helping transport hidden data. This is what secret communication can look like in plain sight. It also got me thinking about Alternate Data Streams (ADS) vs Steganography. Both can be used to hide data inside or alongside another file. The difference is where the data is stored and what forensic artifacts are left behind. 𝐀𝐃𝐒 (𝐍𝐓𝐅𝐒): Data is stored in an alternate stream associated with the file. The primary data stream remains unchanged, and the additional stream isn't normally visible through standard Explorer browsing. 𝐒𝐭𝐞𝐠𝐚𝐧𝐨𝐠𝐫𝐚𝐩𝐡𝐲: Data is embedded into the container itself. Depending on the technique, this can affect the file's structure, metadata, size, or other measurable characteristics. Same objective, different artifacts. Personally, when working with NTFS, I'd lean toward ADS for two reasons. 1. The visible file size stays the same. The hidden data exists in an alternate stream rather than the primary file content. 2. The primary file remains intact. The original data stream isn't modified, allowing the file to continue functioning normally while additional data exists alongside it. That's what makes this interesting from a forensic perspective. A file can look completely ordinary in Explorer while containing data that isn't immediately visible. Simple to implement, easy to overlook. Knowing where to look matters just as much as knowing what to look for.

Let me take you through some devices in our New Pentest and Digital Forensics Lab. A digital forensics laboratory lab especially cannot be considered complete without the right evidence-acquisition, preservation and analysis equipment. Our laboratory is now equipped with: 1. TX1 Forensic Imager — Brand New
Used for high-speed forensic imaging and duplication of digital storage devices while maintaining evidence integrity. 2. Digital Intelligence BlackBox — Brand New
A powerful forensic workstation designed to process and analyse large volumes of digital evidence efficiently. 3. FRED Forensic Workstation 
A specialised system built for forensic acquisition, examination, recovery and analysis of digital evidence. 4. 20 Faraday Bags — Brand New
Used to isolate mobile devices from cellular, Wi-Fi, Bluetooth and other wireless signals, preventing remote access, alteration or deletion of evidence. 5. 11 Hardware Write Blockers — Brand New
Allow investigators to access and acquire data from storage devices without modifying the original evidence. 6. WiFi Pineapple Mark VII — Brand New
A specialised wireless security auditing device used to assess Wi-Fi networks, identify insecure configurations, detect rogue access points and demonstrate wireless attack risks during authorised penetration tests. 7. O.MG Cable — Brand New
A security-testing cable designed to demonstrate how modified USB cables can be used as covert attack tools. It helps organisations evaluate endpoint security, employee awareness and protection against malicious peripheral devices in controlled environments. 8. RFID/NFC Card Cloners — Brand New
Used during authorised physical-security assessments to examine access cards, identify weak RFID or NFC technologies and demonstrate the risks of insecure credential duplication. They are also useful for testing whether access-control systems can detect cloned or unauthorised cards. A proper pentest and digital forensics laboratory requires more than software and ordinary computers. It must have dedicated equipment for the lawful pentest, acquisition, protection, preservation, examination and analysis of digital evidence. These are just a few hardwares out of the many in our closet though😂✊🏽.

SOC Home Lab Series | Part 21 After the SSH work, I moved back to Windows. I wanted to understand what PowerShell activity actually looked like in my telemetry. Windows Security logs gave me one useful clue: Event ID 4688 showed powershell.exe starting.

@GhPoliceService should consider seizing the vehicle itself as digital evidence, not just relying on witness statements or the Uber app. The fact that the trip wasn’t initiated through Uber makes the vehicle’s onboard data even more important. Depending on the make and model, forensic examination of the vehicle’s Electronic Control Units (ECUs) could reveal GPS or navigation history, ignition on/off events, gear selection, steering inputs, vehicle speed over time, accelerator and brake pedal application, ABS activation, harsh braking events, seatbelt status, door lock and unlock events, door open/close timestamps, Bluetooth pairing history, connected devices, and even infotainment logs. They can even recover Event Data Recorder (EDR) information, which can help reconstruct the vehicle’s behavior immediately before a significant event. If the passenger jumped from the moving vehicle, artifacts showing speed changes, sudden braking, or a door opening while the vehicle was in motion could help corroborate or challenge witness accounts. I think it’s about time…
Let’s be careful out there guys!!
