1. It's most likely number spoofing. Some telemarketer is using a robodialer, and they choose numbers at random - that are the same area code (and usually the same business office) that they're calling. (You're more likely to answer if you think it may be someone you know, and you just don't know their number.)
2. Even if WhatApp did make calls, they wouldn't show up in your Phone log, they'd show up in WhatsApp.
I doubt it's malware - why would even a virus script kiddy waste time writing something like that? They do it for the effect, and they have to see the effect. Your phone calling your friend is like their casting an empty bottle into the sea - they'll never know if it did anything - and that's not why people write malware.
