Fortune reporter Robert Hackett here, taking over the weekend duties for your regular host, Heather Clancy. I’ll be cranking out Data Sheet for the next couple of weeks while she’s away.

Have feedback? Reach me on Twitter (@rhhackett) or via email robert.hackett@fortune.com. Or if you have a real juicy tip, let’s chat off-the-record through a messaging service like Cryptocat or Jabber. You can find me at rhhackett@jabber.ccc.de, fingerprint: F225E829 13846232 0709A43A 1ECB83D3 BDDFF6A7. (We can always use good old-fashioned PGP encryption, too.)

TOP INTELLIGENCE

Martyr or marauder? This summer, Facebook punted a prospective intern, Aran Khanna, a Harvard student and developer, for building a Google Chrome browser extension that demonstrated a privacy flaw in Facebook's Messenger app. His tool revealed the locations of Messenger correspondents by scraping users' geolocation data (which was available for anyone in a thread to see) and plotted it on a map. He called it, in a clever nod to Harry Potter, the "Marauder's Map."

For a social network that prides itself on having a hacker ethos—the 'Hacker Way,' as the company has affectionately calls it—Facebook's decision to rescind Khanna's offer seemed to me a contradiction of its cultural tenets. The company had known about the geolocation sharing feature for years and hadn't done anything to address it. It's not as though Khanna's discovery (and app) came as a surprise. Besides, shouldn't the company embrace its own self-professed, hacker-praising principles?

I contacted Alex Rice, a former Facebook employee who happens to be the co-founder and chief tech officer of bug bounty startup HackerOne, a Facebook-backed venture. For him, it seems, Khanna had crossed a line: "Security researchers should always strive to educate the vendor and the public on risks without resorting to generating unnecessary fear, uncertainty, and doubt," he said via email.

Khanna, after all, marketed his tool with phrases like "stalking," and "creepy."

I'm not sure who is in the right here. Perhaps it's naive to think that Khanna's decision to stir the privacy pot should go unpenalized. But it's not as though Khanna was taking part in illicit activities on one of the dark web's most infamous black markets, as an intern at the cybersecurity firm FireEye allegedly did. He merely cobbled together a tool and, in his words, let you "decide for yourself if this is something you should worry about."

Maybe I'm a sucker for the frequently defiant world of wizardry, where insubordination is often the key to survival. Nevertheless, I appreciate Khanna's audacity, though it cost him his summer gig.

ACCESS GRANTED

Fortune's Daniel Roberts rounds the bases on ballpark security with Yankee Stadium's new anti-terrorism tech.

"If you’ve ever spent a long time in line outside a stadium, you know the frustration. You’ve already paid for a ticket, only to wait for the privilege of going inside—where you’ll probably spend more of your money. The New York Yankees know it too. And so the baseball club has partnered with the tech security company Clear to ease stadium entry." Read more on Fortune.com.

EXFIL

“Don’t. Just—don’t.”

An exasperated exhortation directed at bug hunters and penned by Oracle security chief Mary Ann Davidson on the company's blog on Monday. The post didn't last long before the software-maker took it down. “We removed the post as it does not reflect our beliefs or our relationship with our customer,” said Edward Screven, Oracle executive vice president and chief corporate architect, in an attempt to save face.
