A new ransomware called MegaCortex has been spreading around the world since the beginning of May. The ransomware was first spotted in January but there has been distinct increase in the last month. The system is highly automated and uses different techniques to compromise the victim PC. Once it has a hold the ransomware encrypts the users data in batches of 10 files and leaves a ransom note with instructions on how to unlock the data.
MegaCortex appears to be targeted at larger companies at the moment, but that doesnt mean that smaller organisation can relax, these things have a habit of expanding and getting out of control. We have seen an increase in the number of reports about ransomware during 2019 and with the increase in phishing attacks directed en-masse against companies the risks appear to be higher than ever.
