As has been widely reported over the weekend, a new strain of Ransomware (WannaCry) has caused widespread disruption across multiple organisations in numerous countries. The WannaCrypt ransomware spread to devastating effect last week using worm -like capabilities that relied on a recently patched vulnerability in Microsoft’s SMB file-sharing services (MS17-010). WannaCrypt’s victims included the National Health Service, Spain’s Telefónica and numerous other organisations across the world.
This attack underlines the importance of a good antivirus solution along with regular, controlled patching. We would like to reassure all clients that we proactively monitor and patch all networks and can confirm that the MS17-010 security update was deployed when it was released back in March.
We would like to remind all clients to take the following further action to mitigate this threat:
– updates often require a restart so please ensure your computer is shut down at the end of each day
– avoiding opening unknown email attachments or clicking on links in spam emails
– we strongly discourage the use of Windows XP on any home devices
– if you spot anything suspicious please alert the Avalon helpdesk immediately
If you have any questions, concerns, or are seeking further advice please contact our helpdesk by emailing us at firstname.lastname@example.org or on 03333 442 482.
