How is reusing something beyond its intended purpose living off the land?
You've crash landed in a forest with a hatchet. How do you survive without a phone and just the clothes on your back?
You're on an unfamiliar machine. What can you do without reaching out to download convenient tools?
In both instances, creativity is needed to live off the land. There are constraints that prevent solutions expedient in time or space. So you may need to expend both to achieve the same end: writing scripts to bootstrap up, and leveraging vulnerabilities to accomplish workarounds.
If I crash land, I definitely want to know edible mushrooms vs poisonous. But if there’s a cooler full of supplies with a sign that says “help yourself” that’s useful too.
So in the same way as the initial exploit probably could be called "reusing something beyond its intended purpose" LOLBins can help you continue, to get a persistent reverse shell or exfiltrate some data.
(But I guess they theoretically could be used in some Apollo 13-esque scene, trying to get the backup's off some really broken system or something)
In cybersecurity, the concept is that it's easier to go undetected or just get things done if you're a hacker if you can use apps that are already installed on the system versus installing new systems, which will often raise red flags or be locked down. So you learning to see if target system already has GroupChatApp installed and if so, it lets you escalate permissions in a way that otherwise you couldn't do.
Usually they are also signed and do not get detected by AV tools.
