For many users today, how they use technology is defined by mobile devices. Their primary device is not a desktop computer, or even a laptop. Instead, it’s a tablet or a smartphone. Instead of data stored on a hard drive or a USB stick, corporate data is now stored in the cloud and accessed as…Read More
This post is based in part on my remarks at the upcoming Direction 2012 conference in Tokyo on August 7. I’ve been talking about Consumerization and BYOD – bring-your-own-device – for quite a while now. What has changed in that past year since my presentation at the CIO Summit in Singapore? What has changed is…Read More
Mobile malware’s disruptive impact on enterprises continues to see an uptick in prevalence as mobile devices become an increasingly preferred platform to flexibly access and manage data. We recently found 200 unique Android apps—with installs ranging between 500,000 and a million on Google Play—embedded with a backdoor: MilkyDoor (detected by Trend Micro as ANDROIDOS_MILKYDOOR.A).
MilkyDoor is similar to DressCode (ANDROIDOS_SOCKSBOT.A)—an Android malware family that adversely affected enterprises—given that both employ a proxy using Socket Secure (SOCKS) protocol to gain a foothold into internal networks that infected mobile devices connect to. MilkyDoor, maybe inadvertently, provides attackers a way to conduct reconnaissance and access an enterprise’s vulnerable services by setting the SOCKS proxies. Further, this is carried out without the user’s knowledge or consent.
While MilkyDoor appears to be DressCode’s successor, MilkyDoor adds a few malicious tricks of its own. Among them are its more clandestine routines that enable it to bypass security restrictions and conceal its malicious activities within normal network traffic. It does so by using remote port forwarding via Secure Shell (SSH) tunnel through the commonly used Port 22. The abuse of SSH helps the malware encrypt malicious traffic and payloads, which makes detection of the malware trickier.Read More
Trend Micro has identified more malicious Android apps abusing the name of the popular mobile game Super Mario Run. We earlier reported about how fake apps were using the app’s popularity to spread; attackers have now released versions of these fake apps that steal the user’s credit card information.
Super Mario Run is a mobile game that Nintendo first released on the iOS platform in September 2016, followed by the Android version on March 23, 2017. Mobile games have always proven to be attractive lures for cybercriminals to get users to download their malicious apps and potentially unwanted apps (PUAs). This is not the first time that the name of a popular game was abused; we’ve discussed how the popularity of Pokémon Go was similarly abused.Read More
