DHS Warns of ‘TDos’ Extortion Attacks on Public Emergency Networks
Summary: A confidential DHS and FBI alert obtained by KrebsOnSecurity warns that telephony denial-of-service attacks are overwhelming the administrative phone lines of public safety answering points and emergency communications centers, with dozens of such attacks reported across multiple jurisdictions. The attacks follow an extortion pattern in which a caller claiming to represent a payday loan collections company demands $5,000 over an alleged employee default, then floods the target with continuous calls that block incoming and outgoing service.
What you should know: The alert notes similar attacks have hit the financial sector, air ambulance, ambulance and hospital communications, and SecureLogix reports the caller ID changes on every call and traffic moves through multiple carriers, making the floods hard to distinguish from legitimate calls and slow to trace.
