September 2, 2019

Federal prosecutors in California have filed criminal charges against four employees of Adconion Direct, an email advertising firm, alleging they unlawfully hijacked vast swaths of Internet addresses and used them in large-scale spam campaigns.

A Tough Week for IP Address Scammers

May 15, 2019

In the early days of the Internet, there was a period when Internet Protocol 4 (IPv4) addresses (e.g. 4.4.4.4) were given out like cotton candy to anyone who asked. But these days companies are queuing up to obtain new IP space from the various regional registries that periodically dole out the prized digits. With the value of a single IP hovering between $15-$25, those registries are now fighting a wave of shady brokers who specialize in securing new IP address blocks under false pretenses and then reselling to spammers. Here’s the story of one broker who fought back in the courts, and lost spectacularly.
