Think it’s only individual computer users who need to worry about possible hacking into their affairs? Not so – last week, advises the Security Ledger, “Unidentified hackers set off all 156 of the City of Dallas’s civilian defense sirens late Friday evening and early Saturday morning, disrupting sleep for hundreds of thousands of residents. The sirens were activated more than a dozen times, according to a report by the Dallas Morning News. The stunt resulted in a flood of calls to 911 by confused residents and, according to published reports, was the product of a radio-frequency based attack on the sirens, triggering the devices using tones.
Via such incidents, hacking truly becomes an us-against-them security concern.
