ESET, the leader in proactive protection celebrating 25 years of its technology this year, has released today a special free app, ESET USSD Control, mitigating a potentially very dangerous vulnerability flaw in certain Android-based smartphones. ESET is one of the first major antivirus vendors to provide the fix in the form of a free stand-alone app on Google Play. After installing the app, user should check whether their smartphone is open to such attack by using ESET’s USSD test.


This security flaw allows the cyber-criminals to wipe the phone data remotely by making users to visit a URL, either directly or through a single text message, or a QR code.

“ESET USSD Control is an application that allows the user to check potentially malicious phone numbers (USSD codes) before they are dialed (executed) by the default phone dialer. It will block malicious websites as well. Checking for malicious codes before they are executed, ESET USSD Control makes sure all data on Android phone stay safe”,
elaborates Tibor Novosad,
Head of Mobile Applications Section at ESET.

The app displays a warning window each time when a malicious USSD code is found, blocking the execution of the command.* In order to protect smartphone from USSD attacks, user has to make sure that ESET USSD Control is set as a default dialer.


How the original hack works? The purpose of USSD (Unstructured Supplementary Service Data) codes (a code starting with asterisk *, continuing with hashtags # or digits, which represent commands or data, and ending with a hashtag) is that telecom operators can provide distance support for phone devices. An example of such code is one that displays IMEI number, but there are also USSD commands that can restore a phone to factory settings on certain models. Thus hackers are able to delete all your data or reset phone remotely by initiating such request in your device. Ravishankar Borgaonkar, a research assistant in the Telecommunications Security department at the Technical University of Berlin, has raised a question to the AV industry by a recent demonstration of the remote data wiping attack at the Ekoparty Security Conference in Buenos Aires, Argentina.
