Google Chrome Marks ICICI Bank’s Banking site as Unsafe – Attack or False Positive?

Google chrome’s anti-phishing algorithms show false positives? While trying to login to the internet banking website of India’s No:1 Private Bank (icicibank.com). It stopped the browser showing the below page

 

icici webiste blocked

The interesting thing is the URL shown on the screen is different universal-api-dot-icicibank-c4m.appspot.com. But that is having no relation with the target website which is icicibank.com

One possibility is icici bank’s website got injected with the above malicious URL or it can be a false positive from google chrome?
