Bogus emails from CLEAPSS3 Oct 2017
We have been receiving reports of malicious emails allegedly coming from CLEAPSS. 

These encourage the recipient to follow a link, usually purporting to be to an unpaid invoice. 

Having investigated these, we can confirm that these e-mails are NOT coming from CLEAPSS.

Please check any e-mail that appears to be from CLEAPSS carefully.

It is important not to follow any link or open any attachment.
