Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Kernel memory exploitation via unprivileged user namespaces
Why it's wrong here
Kernel exploits deal with runtime OS vulnerabilities, not software package supply chains.
- ✗
Denial of Service via packet flooding
Why it's wrong here
Packet flooding is a network layer attack, not a software supply chain dependency vector.
- ✗
Man-in-the-Middle etcd keystore sniffing
Why it's wrong here
etcd sniffing targets storage encryption or cluster control plane communication rather than package repositories.
- ✓
Typosquatting
Why this is correct
Typosquatting relies on human error where developers misspell dependency names, inadvertently pulling malicious packages into the build.
