What are the Petya and WannaCry ransomware?

Petya / NotPetya, WannaCry, and WannaCry2 are massive global ransomware attacks that are affecting Windows machines that have not been patched to fix the EternalBlue vulnerability.

While they both operate slightly differently as ransomware, what is very disturbing is that they both spread from machine to vulnerable machine. Past versions relied on the end user taking an action--downloading it from the web, clicking on a link in an email, or clicking on a malicious attachment. Petya and WannaCry only needs to be detonated once before they start to spread virally.

Que pouvez-vous faire ?

Two IT experts working with Barracuda product

Que pouvez-vous faire ?

  1. Mettez votre parc informatique à jour le plus rapidement possible. Remarque : appliquer un correctif sur un ordinateur déjà infecté ne bloquera pas le logiciel malveillant. En cas d'infection, éteignez immédiatement votre ordinateur et contactez votre service informatique.
  2. Same basic rules apply as with any email threat. Watch what you click on or download, do not assume anything.
  3. Backup your files immediately – not on a shared folder because ransomware can and will encrypt shared folders. You need a time machine type backup that provides incremental backups and has an air gap that will protect files from being encrypted.
  4. Confirm that you’re subscribed to the latest Barracuda Energize Updates – always keep your systems up to date.
  5. Assurez-vous que la solution Advanced Threat Protection ait été appliquée à l'ensemble des produits Barracuda. Nous observons depuis vendredi une augmentation de dix fois le nombre de menaces bloquées grâce à ATP, d'où l'importance de mettre en œuvre une telle solution de protection avancée sur l'ensemble des vecteurs de menaces et sur tous les produits Barracuda.
  6. If you’re not a Barracuda customer, let’s talk!
