I've taken the main points from that article.
first
On January 19th, 2018, some IOTA users lost their funds to an unknown attacker. The good news: The IOTA technology is secure. The attacker did not leverage any vulnerability.
And second
From what Ive heard, many users who lost their funds created their seeds at iotaseed.io (not linked here for obvious reasons).
It looks a lot of people are still using scam seed generators. This just another kind of what already did by scammer through spreading the fake link of mew site.
this looks very similar in my opinion.
But it looks these scammers have an access to the seed that has been generated by shady site generator.
