It's absolutely victim blaming and it's gross. The bottom line of the law of attraction is that everything is your fault. Everything that happens to you (or doesn't) is the result of your own thoughts. They intend for this to be empowering but it's actually quite offensive.

According to The Secret, for instance, the Holocaust was the result of the Jews having negative thoughts and not the Nazis being monsters. The following is from page 28 of The Secret:

Often people recall events in history where masses of lives were lost, and they find it incomprehensible that so many people could have attracted themselves to the event. By the law of attraction, they had to be on the same frequency as the event. It doesn’t necessarily mean they thought of that exact event, but the frequency of their thoughts matched the frequency of the event. If people believe they can be in the wrong place at the wrong time, and they have no control over outside circumstances, those thoughts of fear, separation, and powerlessness, if persistent, can attract them to being in the wrong place at the wrong time.
