Imo its this type of self replicating AI that is likely to cause the first global AI catastrophe. A worm-like AI, even if not close to human level intelligence, could if autonomous and sufficiently good enough at hacking, infiltrate a huge amount of vulnerable devices, and paralyze all of our computer infrastructure in the process. The fallout could be massive, especially if's disruptive enough to take out our power infrastructure by say overburdening our power control systems. Superintelligence is not necessary for rogue AIs to cause big trouble
