In many cases, a false sense of security causes people to put themselves at much greater risk.

The following article describes a “burner” phone service that re-uses the temporary phone numbers. It appears that number a security researcher received was previously used by a sex worker, who’s customers continued to send pictures and messages to the number after it had been re-assigned.

DOH!

Your Anonymous Posts to Secret Aren’t Anonymous After All | Threat Level | WIRED

This article describes a clever attack against Secret, the “anonymous” secret sharing app.

Their technique allows the attacker to isolate just a single target, so any posts seen are known to be from them. The company is working on detecting and preventing this attack, but it is a hard problem.

In general, any anonymity system needs to blend the activity of a number of users so that any observed activity could have originated from any of them. For effective anonymity the number needs to be large. Just pulling from the friends in my address book who also use Secret is way too small a group.
