Questions you should ask yourself BEFORE you open an email…

Hints and tips to protect yourself against Ransomware

  • Do you recognise the sender’s email address?

    Is it an unexpected or unusual email with an embedded hyperlink or an attachment from someone you haven’t communicated with recently.

    DO NOT CLICK ON HYPERLINKS… hover and check that the link to address is a legitimate website

    Check the time that the email was sent. Was it one that you normally would get during regular business hours, but it was sent at an unusual time like 3 a.m.?

    Check if the sender included an email attachment that you were not expecting or that makes no sense in relation to the email message. (This sender doesn’t ordinarily send this type of attachment)

    Is the sender asking you to click on a link or open an attachment to avoid a negative consequence or to gain something of value?

    Is the email out of the ordinary, or does it have bad grammar or spelling errors?

    Is the sender asking you to click a link or open up an attachment that seems odd or illogical?

    Do you have an uncomfortable gut feeling about the sender’s request to open an attachment or click a link?

    Is the email asking you to look at a compromising or embarrassing picture of you or someone you know?


Ransomware is a type of malicious software that threatens to block access to user or company data unless a ransom is paid. The more advanced strains of ransomware employ a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible and demands a ransom payment to decrypt them. Recovering the files without the decryption key is almost impossible, difficult to trace digital currencies such as Ukash and Bitcoin are used for the ransoms, making tracing and prosecuting the perpetrators difficult.

Ransomware attacks are typically carried out using a Trojan that is disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment or link. Some infections can replicate themselves between computers on a network.

As with other forms of malware, security software (antivirus software) might not detect a ransomware payload, especially in the case of encrypting payloads, only after encryption is under way or complete, particularly if a new version unknown to the protective software is distributed.
