Want to master Windows internals for offensive security?!

Read ...

'Windows Internals, Part 1 & 2'

by Solomon & Ionescu.

It discusses processes, memory management & kernel mechanisms.

Essential for red teamers.

Abusing DbgPrint for stealthy data exfiltration?

Kernel-mode logging APIs let malware smuggle data via debug output, bypassing traditional network monitoring.

Works well in driver-based implants.

#Malware #RedTeam #Data #Network #Kernel #API #infosec #CyberSecurity

On Code Trick:

Need stealthy C2 communication?

Use ICMP echo requests to encode commands & TTL values to exfiltrate data.

Many firewalls ignore ICMP, making it a covert channel.

#RedTeam #C2Evasion #ICMP #infosec #CyberSecurity #TTL

Abusing Windows Error Reporting (WER) for stealthy execution?

Drop payloads in

C:\ProgramData\Microsoft\Windows\WER\ReportQueue\,

then trigger 'WerFault.exe' to load them.

Low detection, high persistence.

The 2014 Heartbleed bug exposed a brutal reality:

even widely trusted cryptographic libraries (OpenSSL) can harbor catastrophic flaws.

The lesson?

Continuous auditing > blind trust.

#CyberSecurity #History #SSL #Cryptography #Bug #Infosec

Abusing Windows COM objects for stealthy execution?

Use 'MMC20.Application' to execute commands outside direct process lineage tracking.

Works well against naive EDR correlation.

Public Wi-Fi isn’t your friend. 🛑

Even with HTTPS, evil twin APs, SSL stripping & MITM attacks are still a thing.

Use a trusted VPN, or better yet .. just don’t connect.

Your data isn’t worth the risk.

2017:
WannaCry spreads like wildfire, exploiting SMBv1 with EternalBlue.

Lesson?

Patching isn't optional.

If your infra still has unpatched, exposed SMB services in 2025, you’re just waiting for the next worm.

When we go back to 2010, Stuxnet attack redefined cyber-physical warfare.

It proved that targeting PLCs can cripple infrastructure without a single bullet fired.

ICS/SCADA security is still playing catch-up.

Kerberos ticket delegation attacks are still underutilized.

Combine constrained delegation with 'S4U2Proxy' to impersonate high-privilege accounts without dumping creds.

Abuse the trust chain.

If you’re analyzing Windows malware, Sysmon + Sigma rules are indispensable.

Sysmon logs deep process activity, while Sigma translates TTPs into actionable detections.

Master both.

Injecting shellcode?

Avoid VirtualAlloc/WriteProcessMemory detection..

Use (NtMapViewOfSection) with a shared memory section between processes.

It bypasses common EDR hooks.

Subtle persistence wins.
