Like others have said, they can "in theory" be dangerous, but wolf attacks on humans are extremely rare in North America. Probably 50x less likely than bear attacks, which are already very infrequent.
I don't know if there is a record in modern times of an actual predatory wolf attack against human using the sort of premeditated pack hunting tactics that
>>2854751 describes, at least in North America. Most attacks are by solitary wolves that have been driven to starvation or are rabid or otherwise sick, or they're in suburban environments and habituated to humans and garbage. The odds of being "hunted" by a pack of wild healthy wolves is like, astronomically unlikely.
