What is ransomware?
Ransomware is a malicious software designed to hold a user’s files (such as healthcare records, financial contracts, manufacturing blueprints, software code, and other documents) for ransom by encrypting them and demanding the user pay a fee (often in Bitcoin) to decrypt them.
How ransomware works
Attackers initiate attacks using an array of tactics. Ransomware infections often first begin with an exploit kit — which are software kits designed to identify software vulnerabilities on endpoints and then upload and execute malicious code on the endpoint.
Although variants of ransomware behave differently — there are many ways that Cisco can help. Download this whitepaper today to find out more.
“Does Cisco Umbrella block ransomware?”
This is one of the most common questions that we hear from customers. In reality, the answer for any security provider — including Cisco — is seldom an absolute “yes” or “no.” It really depends on how each variant arrives onto your systems, as well as its order of operations for encrypting data for ransom.
However, with Cisco you can significantly reduce the number of ransomware infections across your organization.
Ransomware threats like Cryptowall, TeslaCrypt, and Locky are on the rise, targeting organizations of all sizes. This paper explains how these attacks work, and why a large number of new infections continue to surface despite existing protective measures. It also provides practical short- and long-term steps that organizations should take to protect against them.

Affecting over 200,000 machines in more than 150 countries, the ransomware known as Wanna Decryptor, or “WannaCry,” became the largest cybersecurity attack in history in May 2017. The malicious software locked out users from critical data, and demanded a ransom payment to unlock the contents. Governments, hospitals, and corporations scrambled to address the attack and prevent the infection from spreading. Ironically, the virus’ execution method was simple: it exploited a vulnerable Windows SMB protocol to spread – an exploit Microsoft had addressed two months prior to the attack with the release of a patch.

The total amount of damage caused by cryptomalware can be divided into two parts: the ransom and the related losses. Drawing from our survey of over 4,000 small- and medium-sized companies conducted by Kaspersky Lab and B2B International, we take a closer look at the numbers behind the damage.
