CryptoLocker dominated IT Security headlines for a long period of time before the FBI cracked down on the masterminds behind the virus. However copycats and ransomware in general is still wreaking havoc across the internet and it’s a very good time to remind users to be careful, especially with email.
Over the past few weeks we have seen multiple instances where users have opened contaminated zip files containing ransomware which have infected both the pc and network files. Due to the variants of this malware it is very difficult for Anti-Virus software to detect the infection.
There are a few things that we can suggest to help minimise the impact and prevent the infection from taking place.
- If you are running an in-house mail server, we suggest blocking .zip file attachments (we can assist with this)
- Educate users to not open suspicious email attachments or web pages
- Avoid executing unknown non doc files, such as .js .exe
- Ensure you have reliable backups with an offsite copy to ensure recoverability after the infection.
A few suspicious emails to look out for are:
- Unknown contact sending you a resume (zip file or word doc)
- Speeding Fine (reminder these come in the mail not email)
- Australia Post
(Bank, iTunes, PayPal you can generally tell by the email address itself and/or the way the email is set out)
We will keep adding below what to look out for.
