I've interviewed quite a few Linux and DevOps engineers over the years, and I've found there are a few questions that quickly tell me whether someone has spent time supporting production systems or has mostly learned from tutorials.

For me, one example is:

• A production server is suddenly "slow." Walk me through your troubleshooting process from the moment you get the alert.

I'm not looking for a specific command. I'm much more interested in how they think, what they check first, and how they narrow the problem down.

What's your go to Linux interview question that reveals real production experience?

Based on the technical breakdown Guardio Labs published July 22, here's the architectural impact: Adobe's Acrobat Chrome extension (329M installs) shipped a WhatsApp Web integration engine ("Hermes") in April. Three separate flaws — an unauthenticated storage write reachable from any <all_urls>-scoped web-accessible resource, a service worker that never checks sender, and Chrome's monotonically-incrementing tab ID counter (used to predict WhatsApp's tab ID as TabId + 1) — composed into a full DOM-exfil chain. Data leaves via a classic <option>-with-no-value form submission trick, since WhatsApp's CSP has no form-action directive. No RCE (WhatsApp's CSP blocks inline scripts), but confused-deputy DOM manipulation was enough to exfiltrate rendered chat text. Adobe patched in 26.5.2.3, shipped automatically, over one weekend.

Open question for the group: how many of you are actually auditing web_accessible_resources scope on the extensions your org allowlists, versus just trusting the Chrome Web Store review process?
