Today we’re going to explore a newer type of threat: Ransomware or, more precisely, PHP Ransomware. Ransomware attacks have increased greatly over the last few years and many variations have been made and are still being used in the wild. First, we should define what we mean when we talk about Ransomware. We’re specifically talking about a piece of code or software that encrypts your files in place and demands a ransom payment to receive the key that decrypts your files. So, if you are the victim of a ransomware attack and do not have recent, verified backups you could be in trouble! You have no other way to retrieve your files besides paying the ransom unless the ransomware is an old one and security companies have already created the software that decrypts it.

How does a ransomware infect a computer?
Traditional Ransomware usually affects personal computers and is delivered by email or infected websites. Whether in an email attachment or served from a hacked website, possibly using drive-by download techniques, the payload may disguise itself as a PDF, Flash, Adobe or Java update or some other type of executable. According to this PhishMe Q1 2016 Malware Review report, 9 out of 10 phishing emails sent in March 2016 carried a ransomware payload.
