This affects all versions of package com.mintegral.msdk:alphab. The Android SDK distributed by the company contains malicious functionality in this module that tracks: 1. Downloads from Google urls either within Google apps or via browser including file downloads, e-mail attachments and Google Docs links. 2. All apk downloads, either organic or not. Mintegral listens to download events in Androids download manager and detects if the downloaded files url contains: a. google.com or comes from a Google app (the com.android.vending package) b. Ends with .apk for apk downloads In both cases, the module sends the captured data back to Mintegrals servers. Note that the malicious functionality keeps running even if the app is currently not in focus (running in the background).
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

Many communication channels can be “sniffed” (monitored) by adversaries during data transmission. For example, in networking, packets can traverse many intermediary nodes from the source to the destination, whether across the internet, an internal network, the cloud, etc. Some actors might have privileged access to a network interface or any link along the channel, such as a router, but they might not be authorized to collect the underlying data. As a result, network traffic could be sniffed by adversaries, spilling security-critical data. Applicable communication channels are not limited to software products. Applicable channels include hardware-specific technologies such as internal hardware networks and external debug channels, supporting remote JTAG debugging. When mitigations are not applied to combat adversaries within the product’s threat model, this weakness significantly lowers the difficulty of exploitation by such adversaries. When full communications are recorded or logged, such as with a packet dump, an adversary could attempt to obtain the dump long after the transmission has occurred and try to “sniff” the cleartext from the recorded communications in the dump itself.
