Researchers note that the only way to stay safe is to check those URLs and only visit sites that you trust (which isn't very reassuring) and "may or may not be exploitable" from Mac and PC versions of Safari -- the same vulnerability exists only they haven't written the proof-of-concept exploit to test it yet.
Isabella Sankey of Liberty, a pressure group, fears the CPI could be worse than the ASBO, as the standard of proof will be lower and the test of anti-social behaviour broader.
As this is a proof of concept -- and one we couldn't test out, at that -- it's unclear how well these features work, and it's unlikely that we'll ever see the prototype make it to market.
He also advises asking for proof of a tuberculosis screening within the past year, as well as a recent test for community-associated Methicillin-resistant Staphylococcus aureus (CA-MRSA), which can be transmitted by skin-to-skin contact and cause painful skin infections and boils.
