Mobile spyware attacks also see increase.
More than 200 malicious apps have been found in the Google Play Store, with more than eight million installations.
According to research by Zscaler, it said there has been a 101 percent surge in mobile spyware attacks - including a 29 percent growth in banking malware attacks, and a 111 percent rise in spyware year over year.
"Cybercriminals are increasingly targeting legacy exposed assets which often act as a beachhead to IoT & OT environments, resulting in data breaches and ransomware attacks," said Deepen Desai, chief security officer at Zscaler.
"Mobile malware and AI driven vishing attacks adds to that list making it critical for CISOs and CIOs to prioritize an AI powered zero trust solution to shut down attack vectors of all kinds safeguarding against these attacks."
