Head of the UK's National Cyber Crime Unit has reportedly warned that the 'dark web' of criminal activity will continue to evolve.
Andy Archibald said that the services used by criminals will continue to develop in an attempt to evade authorities.
According to the BBC, last week, the Silk Road, a notorious drugs market place was shut down after a lengthy investigation.
Archibald said that officers identified individuals who were using the site and found that new methods were needed to keep up with the threat.
He said that online anonymity service, Tor evolves, and will resecure itself adding that the crime unite has to continually probe and identify those forums and then seek to infiltrate them and use other tools.
The chief further said that just because they were able to infiltrate Tor this occasion, doesn't mean they will be able to do it the next time as well.
His warnings come in light of the unit's first conviction, 27-year-old Olukunle Babatunde, who pleaded guilty to using 'phishing' scams in an attempt to defraud banks, financial institutions and their customers and has been sentenced to a five years and six months of jail term, the report added.
