What is ransomware and example?
Ransomware is a type of malware (malicious software) used by cybercriminals. If a computer or network has been infected with ransomware, the ransomware blocksaccess to the system or encrypts its data. Cybercriminals demand ransom money from their victims in exchange for releasing the data.
Who gets affected by ransomware?
Ransomware attacks target firms of all sizes—5% or more of businesses in the top 10 industry sectors have been attacked—and no size business, from small and medium-sized businesses to enterprises, is immune. Attacks are on the rise in every sector and in every size of business.
Adversaries use three common entryways to infect systems with ransomware. Learn how to prevent your organization from falling victim to an attack
Ransomware is seemingly everywhere right now. This disruptive malware infiltrates and disrupts everything from healthcare organizations to energy distribution pipelines.
Ransomware attack vectors and mitigations
The top three ways ransomware gets onto victims' systems are phishing, Remote Desktop Protocol (RDP) and credential abuse, and vulnerabilities. Let's take a look at these three vectors and how to best secure them to prevent a ransomware infection.
Summary
A few basic security controls can greatly reduce your risk of a ransomware attack.
Initial access vector
The three most common methods that we see threat actors use to gain access to a victim's network are:
Attackers usually go for the easiest payoff possible
More often than not, this means guessing your credentials and logging in. I’d like to take this opportunity to implore all of you reading this to please, please implement multi-factor authentication on your remote access gateways. The presence of MFA is usually enough to deter the attacker and force them to focus on a less secure organization.
Once they are in
After a threat actor establishes a presence in a victim's network, the activities they perform are fairly predictable. We often see them:
One final thought
And as always, logging to a central collection facility is going to be key in detecting badness in your network.
Internet Vulnerabilities and Misconfigurations
To limit the attack surface, regularly scan for vulnerabilities to identify and address vulnerabilities found, especially on internet-facing devices.
Phishing Attacks
Implement a cybersecurity awareness training program with guidance on identifying and reporting suspicious activity or incidents such as phishing. Perform enterprise-wide social engineering and phishing tests to measure user awareness and reinforce the importance of identifying potentially malicious emails.
Malware Infection
A ransomware infection can be evidence of a previous network compromise.
Third Parties and Managed Service Providers
If a third-party or managed service provider is responsible for maintaining and securing your organization’s backups, ensure that they follow the applicable best practices outlined above.
What are the most common ransomware vectors?
Three of the most common ransomware attack vectors are: Remote desktop protocol (RDP) Email phishing. Software vulnerabilities.
Why do hackers use ransomware?
Cyber attackers choose to use ransomware for a number of reasons. As previously mentioned, it can be very lucrative. Organizations are generally inclined to pay a ransom rather than risk interrupting the flow of business and losing consumer trust. Additionally, the margins are good. There are several cheap and easy attack vectors that can be used to launch a ransomware attack. Cyber attackers can put in minimal effort and get maximum payout. Three of the most common ransomware attack vectors are: 1 Remote desktop protocol (RDP) 2 Email phishing 3 Software vulnerabilities
What happens when software is not patched?
In some cases, when software is not properly updated or patched, attackers can access networks without having to harvest credentials. Once in the system, they begin attacking key programs and viewing or exfiltrating sensitive data. Additionally, many types of ransomware have evolved to forms that are difficult to detect, therefore extending their dwell time for maximum destruction.
What is phishing email?
Phishing emails containing links may appear to come from a known contact asking a user to enter credentials for a bogus purpose. Those credentials are then stolen and used to access key systems on which ransomware can be installed.

Is ransomware profitable?
As previously mentioned, it can be very lucrative. Organizations are generally inclined to pay a ransom rather than risk interrupting the flow of business and losing consumer trust. Additionally, the margins are good. There are several cheap and easy attack vectors that can be used to launch a ransomware attack.
Is RDP a good attack vector?
Cheap, easy, and highly available, RDP is the second most popular attack vector by a small margin. RDP ports are often poorly secured and easily compromised. Additionally, RDP security relies heavily on proper password protocol, which can be ignored by users. Less-skilled cyber attackers can easily infiltrate weakly protected RDPs to harvest credentials. Or, if that’s too much work, they can just buy RDP credentials on the dark web, with some selling as cheaply as $20 each.
