You may have seen in the news today that there is a global outbreak of ransomware that could, if activated by a user, encrypt all the data on your PCs and servers, causing a massive amount of damage.
We have previously emailed about a service enhancement on Sophos (which most of our customers have), which CAN help to prevent the activity of this type of infection. A number of our customers have taken this additional service which has helped to contain these threats.
We urge a huge amount of caution at this time. Please advise your staff to be extremely cautious about websites they visit and emails they receive, even from people they apparently know. Email spoofing with links to infected web sites or compromised applications are the primary delivery method of the payload. I cannot stress how destructive this type of attack is.
The add-on to Sophos attempts to protect the systems by detecting unexpected encryption of files and stopping the source of the infection. Normal antivirus without this function IS NOT EFFECTIVE at preventing these attacks.
Whilst your data is protected by system backups, the amount of time required to restore many TeraBytes of lost data along with possibly multiple compromised PC’s would be measured in weeks not hours. Please be mindful that we have many customer who have the potential to be affected.
I reiterate – you must contact your staff urgently and advise MAXIMUM caution. Do not open a link or attachment in an email unless you are absolutely certain that it is legitimate. If something happens and you think a PC has been affected, IMMEDIATELY turn the machine off, even if this means pulling the power cord.
If you wish to upgrade to the InterceptX service from Sophos (assuming you have Sophos with us), we can do this very quickly. It will increase your costs by £2.00 per PC per month. This is not a sales email, it is intended to bring this major global issue to your attention. No amount of technical protection can possibly beat a vigilant user base.
