	"plain_text": "Tornado sirens in Dallas suburbs deactivated after being hacked\r\nand set off\r\nBy Benjamin Freed\r\nPublished: 2019-03-13 · Archived: 2026-04-05 20:43:29 UTC\r\nTornado sirens that went off in two Dallas suburbs early Tuesday morning have been attributed to a small-scale\r\nhacking incident, officials said.\r\nResidents of the cities of DeSoto and Lancaster were awakened about 2:30 a.m. to blaring noise suggesting that a\r\ntornado strike was imminent. At the time, though, overnight weather conditions around Dallas showed\r\ntemperatures in the mid-50s and overcast skies.\r\nSome people who heard the sirens took to social media to vent their frustration at being woken up in the middle of\r\nthe night for a warning about a non-existent funnel cloud:\r\nBut later Tuesday, Lancaster officials issued a press release stating that the false alarm was the work of a hacker\r\nwho had gained access to the system that runs the siren network it shares with neighboring DeSoto.\r\n“Based on the widespread impact to the outdoor sirens located in two separate cities, including Lancaster, it has\r\nbecome evident that a person or persons with hostile intent deliberately targeted our combined outdoor warning\r\nsiren network,” the press release read.\r\nDeSoto officials followed up Wednesday, saying the matter has been turned over to local police. The siren system\r\nhas also been deactivated. In the interim, residents of both suburbs are being advised to sign up for CodeRed,\r\nwhich delivers emergency alerts via phone calls, emails and text messages, and was not affected by the incident.\r\nTuesday’s hack recalled an April 2017 incident in Dallas proper when the city’s network of 156 tornado sirens was\r\nset off more than a dozen times on a Saturday morning by someone who gained access to the city’s radio-based\r\nalert system, with no actual tornado in sight, by transmitting a dual-tone multifrequency signal. The suburban\r\nsiren system runs on similar technology.\r\nOfficials in San Francisco, which also has a radio-based siren network, said last year they upgraded the encryption\r\non their system that they said should be strong enough to throw off malicious radio operators.\r\nSource: https://statescoop.com/tornado-sirens-in-dallas-suburbs-deactivated-after-being-hacked-and-set-off/\r\nhttps://statescoop.com/tornado-sirens-in-dallas-suburbs-deactivated-after-being-hacked-and-set-off/\r\nPage 1 of 1",
