WhatsApp Messenger, WinZip, and Where's My Droid Pro are among the apps most commonly blacklisted by companies allowing their employees to use their devices to connect to their networks.

This is according to the latest quarterly mobile security report, the Enterprise Mobile Security Pulse Report, by Appthority.

The report found that as of August 2017, the most commonly used apps within enterprises were Uber, the Yellow Pages and Facebook in the Android ecosystem, while iOS users favoured WhatsApp, Facebook Messenger and Uber.

In terms of threats, the top three blacklisted apps in Android were Poot-debug(W100).apk, an Android System Theme and Where’s My Droid Pro. These apps all suffered from malware being detected.

Meanwhile, iOS’ top blacklisted apps were WhatsApp Messenger, Pokémon GO and WinZip. Appthority said that iOS apps were largely blacklisted because they scored highly in the data leakage range for sending SMS messages, tracking location or for sending data – including sensitive data – in an unencrypted form.

According to Appthority, companies blacklist apps for a variety of security concerns, including specific malicious or data leakage behaviors, security policy compliance and concerns about shadow data storage.

However, the riskiest apps based on the Appthority Mobile Threat Risk Score were Uber, WhatsApp Messenger and Facebook Messenger in the Android system and Facebook, Pandora and Yelp in iOS.

Appthority said that when it comes to bring your own device (BYOD), many commonly used approved apps are finding their way into enterprises and therefore posing risks to sensitive company information.

Domingo Guerra, president and co-founder of Appthority, said: “Enterprise security teams need to understand which mobile apps are being used, the risks they bring, and how their peers are utilising mobile threat policies to more effectively secure corporate data.”
