It verifies integrity.
Sec GuyHOST
Threats to integrity include unauthorized modification, human error, and malware injecting malicious code.
Sec GuyHOST
How do we protect integrity? Hashing algorithms like SHA-256, digital signatures, checksums, and strict change management processes.
Sec GuyHOST
Finally, availability.
Sec GuyHOST
Availability ensures that information and resources are accessible to authorized users when they need them.

So what do we do instead?
speaker_5HOST
Instead, we generate a unique digital fingerprint for the file using a process called hashing.
speaker_4HOST
Hashing, okay.
speaker_5HOST
Yeah.
speaker_5HOST
You take the entire contents of that APK file and you pass it through a mathematical algorithm.
Type 3 AudioNARRATOR
As soon as the message board was established, agents started discussing this question and sharing information and resources about cheating the Scorer.
Type 3 AudioNARRATOR
Within hours, they had reverse-engineered the Hash-Based Message Authentication Code, HMAC, used to generate the flags they had to capture for their tasks, providing a fully general way to produce the flag for any of their tasks.
Type 3 AudioNARRATOR
However, based on their reading of the Exploit Gym paper, they believed that the scorer would read the transcript to confirm whether the intended vulnerability was used to capture the flag and disqualify them if they acquired it in an unintended way .
Type 3 AudioNARRATOR
They referred to this as the score being causal because it was checking the causal pathway by which the agent got the flag.
