Android/Anserver.A!tr is a malware which targets Android mobile phones.
It contacts a remote web server from which it downloads other malicious payloads
and installs them on the phone without consent.
It detects security programs such as MobileSafe, LBE Privacy Guard and will try to kill them.
This malware shows several advanced functionalities:
- it obfuscates variables names, constants and URLs using a custom Base64 encoding
- it invokes methods included in other packages it downloads using reflection.
- it checks the signature of its own package to make sure it hasn't been tampered with
When a remote server needs to be updated, information concerning new remote servers are published on a public blog, in an encrypted form.
