The latest web surf by the Financial Services Authority and other international watchdogs has identified 28 UK internet sites as being in breach of the law.

The FSA took part in the second international surf day in April, which involved 41 regulatory bodies from 34 countries looking for internet scams. The surf was organised by the International Organisation of Securities Commissions (IOSCO), as part of its effort to promote cooperation in the identification, investigation and prosecution of unlawful activity on the web.

The FSA identified 28 sites in the UK and 35 overseas sites that appear to offer unauthorised investment advice and investment deals, or advertised investment products, in breach of the law.

The FSA will undertake further investigations into the sites it identified in this country and has passed on information on the overseas sites to the relevant domestic enforcement agencies.

"The internet has opened up new opportunities for consumers and the financial services industry, providing consumers and firms with the benefits of lower cost, more choice and greater speed in access to the markets," said Carol Sergeant, FSA managing director. "Unfortunately, these benefits also provide new opportunities for those intent on undertaking unlawful activities on a global basis."

There are four steps consumers can take to ensure safer use of online financial services, according to the FSA:

• Know who you're dealing with;

• Check for a secure connection;

• Use passwords and PIN numbers sensibly;

• Protect your computer from viruses;

• You can also check a firm is authorised by calling the FSA Consumer Helpline on 0845 606 1234.
