Questions about HummingWhale virus
HummingWhale virus is an improved version of the infamous HummingBad malware. It is an Android virus, which managed to compromise more than 10 million Android devices in 2016. It appears that this Android malware has made a comeback with more than 20 malicious apps on Google Play Store. According to Check Point’s analysis, this well-made malware predecessor used chain-attack tactics and set up a rootkit on the device to gain full control of it. However, HummingBad was evolved, and in 2017, the gang called Yingmob, which is responsible for these malicious attacks against Android users, released updated malware samples. All of the malicious programs pretend to be applications that have something to do with Android’s camera and are uploaded to the Google Play Store by fake Chinese developers. Here are some examples of malicious programs that contain HummingWhale Trojan:
Whale Camera, Smile Camera, Swan Camera, Coco Camera, Sweet Camera, Ice Camera, Happy Camera, Hot Camera, Shell Camera, Rainbow Camera, HiPorn, Light VPN-Fast, Safe, Free, Beauty Camera, File Master, and more.
Victims who have installed any of these malware samples typically leave one-star complaints on Google Store, saying that the program is worthless and closes right after opening it. Research shows that these programs tend to register some events on boot, including TIME_TICK, INSTALL_REFERRER, and SCREEN_OFF. Every malicious application has a huge 1.3MB file named assets/group.png, which was encrypted. What is more, these applications contain a group.png file, which is actually a .apk file, which means it is a file that can be executed as a program. Exactly this file carries a malicious payload and works as a malware installer. It is capable of installing additional malware to the device without even asking user’s permission. It uses a plugin known as DroidPlugin to upload downloaded applications on a virtual machine, which allows criminals to install many applications without making the compromised device lag. There is also a Command and Control center associated with the malware, which delivers bogus sponsored content and malicious applications. Everytime the victim attempts to close the ad, the malware transfers the additional application to the virtual machine. An unreal referrer ID is then generated, and this way culprits manage to generate revenue without hassle. This highly sophisticated malware sample hides its presence completely, helping its authors make large sums of money without being caught. It goes without saying that HummingWhale removal is a must-do task, and it should be done with the help of a strong anti-malware program that is compatible with Android. We highly suggest you remove HummingWhale malware using the Malwarebytes MalwarebytesCombo Cleaner software.
