OverTheGeicoE writes "The Wall Street Journal has a story describing how the portable radios used by many federal law enforcement agents have major security flaws that allow for easy eavesdropping and jamming. Details are in a new study being released today (PDF). The authors of the study were able to intercept hundreds of hours of sensitive traffic inadvertently sent without encryption over the past two years. They also describe how a texting toy targeted at teenage girls can be modified to jam transmissions from the affected radios, either encrypted or not."
