SecureCircle Prevents Exfiltration Ransomware

What is Ransomware?

Ransomware is a type of malware that uses encryption to hold a victim's data at ransom. A victim's data is encrypted, so they cannot access data. The attacker demands a ransom to restore access to the encrypted data.

There are a few different types of ransomware, and attackers can use a combination of attacks at the same time:

  • Locker ransomware locks the victim out of their computer.
  • Crypto ransomware prevents the victim from accessing their files, usually through encryption.
  • Exfiltration ransomware transfers data from a computer to a remote location. Attackers extort a ransom in exchange for not releasing data to the public.

Who is impacted by ransomware?

Per Sophos' State of Ransomware 2021 report, 37% of organizations were hit by ransomware last year. Ransomware impacts companies of all sizes, but larger enterprises are most likely to be attacked. Likewise, ransomware impacts all industries, but retail, education, and business & professional services were the most impacted in the past year.

Data exfiltration ransomware attacks are up 133% year over year as attackers can extort the most amount of money in these attacks. As a result, victims are also more likely to pay ransoms.

What is the cost of a ransomware payment? While the average amount in the Sophos report was USD 170,404. Two victims paid USD 3.2 million. In addition to the ransom itself, organizations spend on average USD 1.85 million to remediate the breach and resolve compliance and privacy issues. IBM reports the total cost of a data breach in the United States to be USD 8.64 million.

How to prevent ransomware?

  • 1. Assume attackers will target you at some point. Attackers are constantly looking for new revenue, so it is only a matter of time before your geolocation, industry, or company size is the target. Use a Zero Trust DLP solution that persistently protects data. Zero Trust DLP will eliminate the exfiltration ransomware threat vector. Attackers would only be able to steal encrypted data that would be useless to release to the public.
  • 2. Make backups and ensure the backup data is isolated from the production users and devices. Many victims end up paying ransoms because backups were not available, corrupt, or would take too long to restore. Ensuring your organization can restore to a safe point in time is critical to avoiding locker and crypto attacks.
  • 3. There is no one solution to prevent ransomware. Deploy multiple security solutions that focus on different attack vectors or steps within the ransomware process. Endpoint Detection and Response (EDR) prevents malicious applications from being installed or running on devices. Zero Trust DLP will monitor data access and data movement. Together EDR plus Zero Trust DLP prevents damage from ransomware by limiting the scope and detecting attacks early.

How SecureCircle addresses Ransomware?

SecureCircle's Zero Trust DLP secures all data by default, so if a ransomware attack transfers data from the device, attackers will only see encrypted data. SecureCircle encrypts each file with a unique AES256 encryption key, so attackers would need millions of years on the world's fastest supercomputer to brute force and break the encryption of just one file. SecureCircle eliminated exfiltration ransomware attacks.

SecureCircle can't prevent locker or crypto attacks. Through SecureCircle's integration with the operating system and file system, SecureCircle is aware of all file creation, copy, modification, rename, move, and deletion. These actions are all core functions of any ransomware attack. SecureCircle sends all the metadata information to a SIEM such as Splunk for reporting, alerting, and analysis. Any abnormal behavior can be used to create alerts and automatically disable devices.

Why do customers choose SecureCircle to prevent ransomware?

  • Remove users from the security process - SecureCircle transparently and persistently secures data as it leaves applications. Data is always encrypted regardless of whether it is at rest, in transit, or in use. At no point do users need to make decisions on what data is essential or sensitive; data is simply protected by default.
  • Transparent and frictionless to users and applications - When data moves onto endpoints, SecureCircle transparently encrypts the data in a way invisible to both users and applications. This transparent approach means that user behavior does not need to change, and applications do not need to integrate in any way to take advantage of the control and security that SecureCircle delivers.
  • Rapid and simple deployment - Unlike many traditional solutions, SecureCircle works on a simple cloud to agent delivery model, which means a fast and simple deployment, which allows our customers to implement security for their most sensitive data rapidly.
  • Reduce cost and complexity - SecureCircle has a simple per-user pricing model that reduces our customers' costs. SecureCircle further reduces cost and reduces complexity by avoiding the need for multiple products, software integrations, and ongoing security controls & administration.

SecureCircle eliminates data exfiltration ransom attacks and provides early warning metrics for locker and crypto-ransomware attacks.
