Researchers have long bemoaned the insecurity of certain “security” cameras. Ostensibly installed to deter and thwart intruders, many actually can be transformed into an arsenal that hackers use for Web warfare. The latest cause for concern: A vulnerability that enables hackers to summon a firehose of network traffic from hundreds of thousands of such devices for “distributed denial of service” attacks. Scanning the Internet for devices vulnerable to “LDAP” hacking using Shadowserver, a search tool provided by a nonprofit security group of the same name, reveals nearly 15,000 devices ready for abuse. For WS-Discovery, the newly discovered attack method, more than 800,000 vulnerable devices appear to be open to abuse.
