As Computer Weekly revealed last week, under existing UK law police computer crime units are unable to act against junk marketing companies that use hijacked e-mail addresses to send out tens of thousands of e-mails.
Real Time Associates, which makes Modular 2 compilers, complained to Demon last week after its e-mail address was hijacked by a US company advertising a device to descramble cable television channels. "Over the past week we have been deluged with undeliverable mail messages. It is a real pain," said managing director Steve Collins.
Earlier in the year, Real Time's Demon Internet account was hijacked by another marketing company to send out junk e-mails advertising cut-price Viagra.
Another company, Mimosil Technology, said its domain name had been hijacked twice by companies sending out spam e-mails advertising loan services.
Thus, which owns the Demon Internet service, said there is little it can do to prevent the spamming.
