First Serious Threat to Cellular Phones Causes Quite a Stir: RexSpy - King of Trojan Spies

MUNICH, Germany, November 15 /PRNewswire/ --

- SecurStar: Cell Phone Vulnerabilities Detected

Privacy is a thing of the past. The unthinkable has occurred: No mobile communications between people are transferred over a wire line, and no more SMS messages can be sent without potentially being recorded by third parties, competitors or spouses. Simply by sending an invisible and unnoticeable SMS message to a particular cell phone, spying on cell phone users has become child's play. Wilfried Hafner, CEO of SecurStar GmbH, has developed a Trojan horse, named "RexSpy", solely for demonstration purposes. The results are alarming. When the Trojan invades the system, the security vulnerabilities discovered by Hafner show the possibility of eavesdropping on any cell phone. The company gives advice on protection and offers a security tool free of charge that can be downloaded immediately at

In the past, information about cell phone viruses was sporadically disseminated through the media. Until now, however, these bothersome viruses were not enough of a threat to be taken seriously. The security vulnerabilities discovered by Wilfried Hafner and the RexSpy Trojan represent a new benchmark in combating these threats. Hafner has kicked up a storm during the security exposition "Systems" in Munich, by demonstrating the discovered vulnerability and the real danger threatening cell phone users today. Using an undetectable SMS message, completely invisible to the operating system, everything is over in a matter of seconds: the SMS sender can spy on the cell phone user around the clock, as long as the cell phone is in use. All SMS messages can be read and all conversations can be listened to. The surrounding areas can be monitored via the infected cellular phone. The Trojan can also access and forward complete address books. What's so alarming is that any programmer can develop a similar Trojan horse application without any great investment of time or effort. If anyone were to circulate such a malicious virus, it would have devastating consequences.

Tough luck for eavesdroppers: Using the tap-proof PhoneCrypt

SecurStar is offering the comprehensive security solution, PhoneCrypt, in addition to the Anti-Trojan tool (which is offered free of charge), to protect against all "electronic eavesdropping," be it via Trojan horse viruses or other professional eavesdropping tools, such as IMSI-Catcher. This solution is not only for individuals, but also for organizations and people working in the public eye, such as politicians and attorneys, and allows them to protect the information exchanged over their cell phones. The solution actively eliminates the risk of the conversation being monitored or overheard since it effectively eliminates eavesdropping by third parties using military-grade encryption. This is a pure software solution for secure verbal communication developed for cell phones, using Microsoft Windows, without impairing the original functionality. A Symbian-based version for pocket computers and smart phones is in developmental stages as well.
