Scammers and conmen look set to cash in on new coronavirus safety rules designed to protect us from the virus.
On June 15 it will become compulsory to cover your face while travelling on public transport.
But with masks not the easiest to find, it's a perfect opportunity for fraudsters to con people out of cash.
Emails have already been reported to the National Cyber Security Centre showing criminals exploiting coronavirus through fake offers of face masks and testing kits.
Commander Karen Baxter from the City of London Police said: “While the world is coming together to combat this global health crisis, criminals are intent on exploiting our unease, anxiety and vulnerabilities in these unprecedented times."
Last month, when guidelines were changed to advise people to cover their faces when in crowded places like shops, NCSC reported a rise in cyber crime exploiting the coronavirus pandemic.
These included scam web pages claiming they sold coronavirus linked bogus products such as testing kits, face makes and even vaccines.
And people are falling for them.
Overall, Action Fraud figures show £5,142,265-worth of fraud has been reported since February, with the number of reports totalling more than 2,100.
More than 11,500 reports of coronavirus-themed phishing scams have been made to Action Fraud as fraudsters impersonate a variety of organisations dealing with measures to limit the spread of Covid-19.
But criminals aren't stopping at sending emails and building fake websites.
TSB, which promises to reimburse genuine victims of fraud, said one customer from Scotland in their 30s was tricked by a scam on an online marketplace involving a bike.
The fraudster claimed to be an NHS worker who was self-isolating, which led to the customer paying £200 via bank transfer.
Another customer in their 50s from the north-west of England was reimbursed £102 after falling victim to a doorstep scam when a fraudster offered to do their shopping but instead withdrew cash from their card without consent.
Simon Blackburn, chairman of the Local Government Association's safer and stronger communities board, said: "People need to be cautious. If something doesn't seem right or sounds too good to be true, don't hesitate to end a phone call, bin a letter, delete an email or shut the door."

The most dangerous scams to be aware of right now
TSB and fraud prevention body Cifas have identified the most common Covid-19 scams Britons have been targeted with during the pandemic:
Ashley Hart, head of fraud at TSB, said: "The coronavirus pandemic has seen fraudsters unleash an unprecedented wave of attacks across the UK with complex new scams targeting people at an already difficult time."
Mike Haley, chief executive of Cifas, said: "Fraudsters are using the coronavirus pandemic to steal money and personal information from innocent members of the public, and we are hearing of new and emerging scams on a daily basis.
"More than ever, people need to be hyper-vigilant of fraudulent activity and not let criminals take advantage of their fear and uncertainty during this difficult time."
