I had someone ask me for my Android build and baseband number in an effort to help me root my Samsung 6S. Shortly afterwards my phone got really slow as if the CPU was processing large amounts of data. In an hour I checked my mail, and a few were sent back to me that I was not sending. As if a malicious bulk mailing came from my phone, and the old addresses of contacts that were invalid, sent the mail back to me.
Is this unrelated malware or and actual attack perpetrated (theoretically) by this person? Thsnks.
