The fixes Apple bolted on to iCloud's security following its epic spill of stolen celebrity nudes may be far from perfect. But give Apple credit: It made a lot of sex-starved hackers very unhappy.

Late last week, Anon-IB, the anonymous image board that served as one of the central forums for hackers stealing and sharing nude photos from iCloud, came back online after a prolonged "maintenance" outage. The thousands of archived posts in its "/stol/" section, devoted to discussion of how to crack iCloud and steal unwitting victims' compromising selfies, have been deleted. Those posts have been replaced with new ones from frustrated hackers lamenting that their sext-stealing hobby isn’t what it used to be.

“The game is over,” wrote one forlorn Anon-IB member. “We lost despite a major lead.”

Angry users on the site blamed the high-profile celebrity nude leak for ruining iCloud hacking techniques they’d used for months or even years to silently download backups from iPhone owners. “I'm pretty sure J-Law, Kate Upton, McKayla Maroney, their lawyers, and the people who released the nude photos fucked it up for us,” wrote one user, referring to some of the celebrity victims of the photo scandal. “I'd rather be able to download backups of all of the chicks I know than a bunch of random celebs,” complained another.

The exact tactics Anon-IB's hackers used still aren't entirely clear. But in many cases, they seem to have guessed answers to their victim’s security questions that allowed them to reset passwords, exploited a vulnerability in Find My iPhone that allowed them to try thousands of passwords until they broke in, or tricked users into entering the credentials on phishing websites. Then they used law enforcement forensic tools like Elcomsoft Phone Password Breaker to download entire devices’ collections of stolen data.

Apple moved last week to stop those embarrassing hacks: It now alerts users whenever their iCloud data is downloaded to a new device. And it allows two-factor authentication for iCloud accounts, so people can log in or download backups only after also entering a temporary passcode sent to their phone.

Only a small fraction of iCloud users have likely turned on that second-factor security measure, according to Elcomsoft CEO Vladimir Katalov. He says his company's support team has received fewer than ten complaints from law enforcement customers about two-factor authentication preventing Elcomsoft's tools from downloading a target's backup, despite well over ten thousand customers using the software. When two-factor authentication isn't enabled, he says Apple's changes haven't prevented Elcomsoft's tools from siphoning iCloud backups. "In that case, of course it still works," says Katalov.

Anon-IB's hackers seem more upset, however, about the email alerts Apple now sends to its users when their account is accessed or a backup downloaded. That measure cuts the time any hacker has to download a device's iCloud backup after testing the user's credentials, says iOS forensics expert Jonathan Zdziarski.

"Y'all stupid muthafuckas fucked it all up...Now everything alerts," writes one Anon-IB member. "Let it go. The game is up. And we lost."

With most iCloud users still at least partially vulnerable, don't expect the hacking to stop altogether. One Anon-IB member suggested on the site that "/stol/" move to a dark web site protected by the anonymity software Tor; a Tor-hidden site known as iRip already serves a similar purpose. (Cautious users would be wise to turn on two-factor authentication for their iCloud accounts immediately.)

iCloud's hackable vulnerabilities only came to light after a hacker—likely the Anon-IB user known as "Original Guy"—offered to sell a sprawling collection of more than a dozen celebrities' nude photos in exchange for bitcoin. But the discussion on Anon-IB implies that the actual theft of those photos may have been a team effort. "Like 90 people did the work and now 1 or 2 morons are profiting and fucked everything up," writes one user. "So goes the world."

Other denizens of Anon-IB seemed less upset that Original Guy had made Apple cut short their hacking games than the fact that he or she had failed to actually publish the full trove of nudes. Several users claimed that more celebrity sexts have yet to surface.

"The person that leaked the celebrity pictures that everyone on here worked so hard to hack didn't even release all of them," wrote one disappointed Anon-IBer. "That is the real shame. Not that you guys won't be able to hack the Apple iCloud anymore due to Apple's new increased security measures."
