Android Trojan Banking App Targets Master Key Vulnerability

Sluggish Android updates put users at risk. Could rising public awareness of the flaw lead carriers and device makers to patch more quickly?

Security researchers have spotted a legitimate banking app for Android smartphones and tablets that has been "trojanized" using the so-called master key vulnerability. That flaw, which affects all versions of Android prior to version 4.2.2, can be used by attackers to inject malicious code into a digitally signed, legitimate Android app.

In this case, attackers have been offering a trojanized update for a legitimate online banking app distributed by South Korea's NH Nonghyup Bank. The Android app is used by up to 10 million people.

Running the malicious app triggers a screen asking users to enter their account details. "Should the user comply, their information would be sent to a remote malicious server controlled by the cybercriminal," said Peter Yan, a Trend Micro mobile security engineer, in a blog post. In other words, people who fall for the attack would be likely targets for cybercriminals trying to drain their bank accounts

re: Android Trojan Banking App Targets Master Key Vulnerability
Mathew I really enjoyed reading your article. I have to tell you, while working on my capstone project, which is an
Android application, I consulted various how-to's posted online. While looking
at them, I noticed a huge amount of security flaws. I created a list of some of
the most common errors that I found, and a section on how to properly remediate
them. I wrote this article that is mainly focused on Android development, but
it applies to other categories as well, hope to enjoy it: http://blog.securityinnovation...
