Ransomware: The Reality

3 932 vues

Publié le

Ransomware has quickly become the most profitable type of malware ever seen, on its way to becoming a $1 billion annual market.

It's commonly delivered through exploit kits, malvertising (infected ads on a website that can deliver malware), phishing (fraudulent emails masquerading as trustworthy), or spam campaigns. The actual infection can begin when someone clicks on a link or an attachment in phishing emails. Infections can also happen when users surf to sites with malicious ads that automatically infect computers.

Given that ransomware can penetrate organizations in multiple ways, reducing the risk of ransomware infections requires a portfolio-based approach, rather than a single product. Ransomware must be prevented where possible, detected if it gains access to systems and contained to limit damage.

Cisco Ransomware Defense calls on the Cisco security architecture to protect businesses using defenses that span from networks to the DNS layer to email to the endpoint. It is backed by industry-leading Talos threat research for the ultimate responsiveness against ransomware.
