利用泄漏的基带码和开源GSM手机固件，研究人员能让一部GSM手机屏蔽周围人的来电和短信。论文发表在上周举行的Usenix Security Symposium会议上。研究人员称，在理论上，一部手机可以屏蔽一个基站网络覆盖范围内的所有手机。通常情况下，当电话或短信通过网络传输，一个手机塔会寻呼周围的设备以找到正确的接收对象，正常情况只会有一部手机回应呼叫。然而利用修改过的固件，黑客手机能比受害者的手机更快的回应呼叫，导致受害者的手机无法收到电话或短信。根据研究人员的计算，只需要11部修改过的手机就能关闭德国第三大手机运营商的服务。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
