I hate technical rounds 😭
What do you mean I’m expected to write code completely on my own, from memory, under pressure, while someone watches me, without Google, without Stack Overflow, without docs, and somehow remember the exact syntax for everything?
In real life, no one codes like that. Half of software engineering is knowing what to search for, reading documentation, and figuring things out as you go. But in a technical round, apparently I’m supposed to become a human compiler and instantly recall every method, edge case, and framework API I’ve ever touched.
You’re testing my coding skills, my memory, my stress tolerance, and my ability to pretend I’ve never opened a browser, all at the same time 😭
There's a hacking technique called Heaven's Gate.
Here's how it works.
Windows needs to run old 32-bit software on modern 64-bit systems. so it built a compatibility layer called WOW64. think of it as a translator sitting between old software and the new operating system.
Most security tools monitor 32-bit processes. they look for suspicious API calls, unusual behaviour, malicious patterns. they're good at it.
Heaven's Gate exploits the gap.
malware arrives as a 32-bit process. looks harmless. security tools see it, scan it, flag nothing. then it quietly flips a switch in the processor, changing the CS register from 0x23 to 0x33 and suddenly it's executing 64-bit code.
The security tool is still watching the 32-bit side.
The malware is already operating on the 64-bit side.
Ransomware groups use it. state-sponsored actors use it. It's been found in banking trojans, loaders, and remote access tools.
Windows 10+ partially mitigated it with Control Flow Guard.
partially.
It has since been recreated on Linux.
Named after the idea of ascending from a restricted environment to a less restricted one.
The name actually fits.

grep, cat, cut, find, ls, less, sed.
built decades ago by engineers who just wanted tools that actually work
still crushing bloated modern stuff every day
never needed a redesign, never needed a logo
just does the job, quietly better than almost anything else
