NEW YORK (AP) – The danger from a global cyberattack that spread to some 150 nations continues to fade, and that’s only some of the good news.

After two security researchers greatly slowed down that attack , which effectively held people’s documents, photos and other digital files hostage, hard-hit organizations such as the U.K.’s National Health Service seem to be bouncing back. While it’s a crude measure of the impact, it also appears that relatively few of those affected were desperate enough to actually pay the ransom demanded by the attackers.

On the other hand, the attack has served as a live demonstration of a new type of global threat, one that could encourage future hackers.

Here’s what we currently know about the ransomware known as WannaCry, which locked up digital photos, documents and other files to hold them for ransom.
