Ransomware has more than doubled year-over-year**, and attackers are targeting organizations of all sizes — no-one is immune. They are increasingly employing more sophisticated attacks and defeating existing defenses

Anatomy of a ransomware attack
Attacks often start with a malicious phishing email intended to trick the recipient into disclosing login credentials. Attackers may also purchase stolen credentials on the dark web.
Using stolen credentials or other means, attackers hit your website and applications to access your business data.
With access to your data, the attackers encrypt your data so that you can’t access it. They then demand a ransom payment to unencrypt it and avoid exposing that data.
Barracuda is uniquely qualified to protect your business from ransomware, as we provide effective solutions to defend against every step of today’s ransomware attacks. Barracuda provides the email, application/access, and backup protection solutions required to keep your business secure.
Malicious email is one of the most common ransomware attack vectors, with phishing emails used most often to trick users into clicking malicious links or attachments to obtain user credentials.
Email attacks are becoming increasingly complex and dangerous. Attackers use social engineering tactics to bypass traditional email security and trick users into clicking malicious links or attachments and disclosing their login credentials. Barracuda Email Protection combines the traditional email gateway with AI-enabled phishing and account takeover protection to detect and stop these costly attacks.
Your users are your last line of defense. Educate them about the latest email threats, and ensure they understand their fraudulent nature and know how to report them to your security teams. Barracuda security awareness training and phishing simulation provides all necessary tools to train your users to recognize and report phishing emails, which will prevent email fraud and data loss.
Email attacks that evade email security and land in your users’ inboxes need to be addressed quickly to prevent damage and limit the spread of the attack. Barracuda’s incident response automates post-delivery remediation, enables proactive threat discovery, and streamlines remediation of unwanted emails directly from all affected user inboxes. This automated process can help you to address post-delivery threats in minutes rather than hours or days.
Ransomware attacks target your data for encryption and exfiltration. Web applications are the top attack vector for data breaches. Over 90% of data breaches resulted from hacking of web applications. To implement an effective ransomware protection strategy, you need to secure your applications, protect access to your applications, and prevent lateral movement on the network.
Web applications such as web forms, e-commerce sites, customer service portals, and partner portals are targets for bad actors and malicious bots. Applications often have vulnerabilities that can be exploited to gain access to your data or to penetrate your network. These attacks may use credentials obtained through social engineering attacks or purchased on the dark web. Barracuda provides powerful, comprehensive application security that is easy to deploy.
In addition to protecting the application itself, it is also important to protect access to the application. For applications used by employees and partners, you should only allow access for authorized users and devices. Barracuda provides a Zero Trust Access solution that can protect access to your applications and workloads.
Once attackers gain access to the network by hacking through a web application, they will often attempt to move laterally through the network to find data sources. To block that movement, you can segment your network and protect each segment. Barracuda can enable network segmentation and stop lateral infection of the environment.
If ransomware does take control of your data, there’s no need to pay a ransom or go through a difficult and tedious recovery process — if you have a strong, modern, easy-to-use backup solution. Barracuda offers superior backup solutions — on-premises or in the cloud — that make it simple and fast to restore an up-to-date copy of any file, whether you’re restoring an entire server or specifically selecting files to restore.
The FBI’s top ransomware recommendation is to have a good backup of your important data. The reason — it’s the only way to recover without paying a ransom. Attackers know this too and want to find your backup systems and encrypt them so you can’t use your backups to recover. Barracuda’s backup solution runs on a hardened Linux platform, which makes it less susceptible to ransomware attacks and does not present as a network share, which makes it harder for attackers to access.
Consider all the data that you need to run your business. You need to back up all of it whether it is on-premises data or in the cloud — everything can be a ransomware target, including Office 365. Barracuda Cloud-to-Cloud Backup can protect your Office 365 data, while Barracuda Backup protects your onsite data with encryption and controls access to your data with role-based access control and multifactor authentication.
Attackers want to steal your important data, exfiltrate it, and then demand payment for the return of that data. Backups are a prime target as all the important data is in one place. Barracuda encrypts the data at rest, in transit, and in the secondary location so that attackers can’t read the data, making it much less valuable to them.
The best time to fight ransomware is before it strikes — you don’t want to be trying to put together a plan during an attack. Barracuda can help you develop a plan that covers important attack vectors while protecting your data.
