When users enter their login information, it goes into the hands of malefactors.
However, dating sites provide phishers with a unique opportunity to prey on the emotionally vulnerable.
By impersonating a potential partner, building up a relationship online and then claiming to be in financial distress, a cunning phisher could scam a well-meaning but gullible user out of thousands of dollars.
This is less efficient than hacking bank accounts, but much harder to trace and potentially much easier to pull off.
Scamming unsuspecting lovers via dating sites is not uncommon, but people can usually spot a fake profile from a mile away.
Compromising legitimate profiles is a much smarter, albeit more insidious, way to go.
