Humberside Police are warning people to beware of a new email scam by criminals claiming to be from Royal Mail. They've targeted businesses and personal users, persuading the victim to click on a link within the email that infects their computer with CryptoLocker ransomware.
The ransomware encrypts the victim’s system and a window appears requesting a payment, to be made in Bitcoins, in order to decrypt the files. Often it warns that unless between £300 to £360 is paid immediately, the cost will rise to £600 to £660.
The emails sent fall into two types:
It states Royal Mail is holding a letter and there will be a £5 per day charge if it is not collected. The email then instructs the victim to click on a link to get it resent, but instead the link infects the operating system with the ransomware. The second form of email states a parcel could not be delivered and is awaiting collection. A link on the email is provided for more information. This takes the victim to what looks like part of the Royal Mail website, where the victim is asked to enter a code – believed to be in the original email.
Once this is entered, the victim is instructed to download an application. Instead, the ransomware is downloaded.
