More than 600,000 internet routers belonging to a single internet provider were taken offline during a three-day period in October.
Security analysts from Lumen Technologies’ Black Lotus Labs detailed the attack in research published Thursday. All of the routers were leased by a single internet provider and were rendered permanently inoperable, requiring a hardware-based replacement. Nearly half of all the company’s modems were abruptly taken offline over those three days in October.
“The event was unprecedented due to the number of units affected — no attack that we can recall has required the replacement of over 600,000 devices,” Lumen’s researchers wrote. “In addition, this type of attack has only ever happened once before, with AcidRain used as a precursor to an active military invasion.”
