Menlo Security Illustrates Importance of Browser Security as 4 in 5 Ransomware Attacks Include Threats Beyond Data Encryption

Menlo Security, a leader in browser security, shared results from the CyberEdge Group’s 10th Annual Cyberthreat Defense Report (CDR). This year’s report, sponsored in part by Menlo Security, highlights the growing importance of browser isolation technologies to combat ransomware and other malicious threats. This continues to be critically important as the research revealed that 78% of ransomware attacks include threats beyond data encryption.

Threat actors know today’s employees spend most of their time working in their web browser, making it both a critical business asset and an attractive attack vector if not properly protected. More than half (51%) of respondents use some form of browser or Internet isolation to protect their organizations, with another 40% planning to deploy this type of technology in the next 12 months. Furthermore, 33% of respondents noted that browser isolation is a key element of their cybersecurity strategy for protecting against sophisticated attacks such as ransomware, phishing and zero-day attacks.

This growing focus on browser security is validated by CDR findings that four in five respondents said that when victimized by ransomware attacks, which are often delivered through the browser, they faced the consequences of multiple threats if they did not pay the ransom. These multi-level attacks included threats to publicly release exfiltrated data (40%), notify customers/media of a data breach (42%) or commit a DDoS attack against the organization (42%).

“Evasive web threats, including Highly Evasive Adaptive Threats (HEAT), often come through the web browser and easily bypass multiple layers of detection in prominent security technology, resulting in malware, compromised credentials, and, many times, ransomware,” said Mark Guntrip, senior director of cybersecurity strategy at Menlo Security. “The CDR shows that the risk of ransomware delivered via a HEAT attack is becoming even more serious, with multiple threats in one payload. Preventing it is critical and browser isolation technologies are a highly effective way to do so.”

This year’s CDR notes browser isolation as an up-and-coming technology that allows employees to perform activities such as accessing websites, opening emails and downloading documents in an isolated environment in the cloud. Because the browser session is isolated, any malware, ransomware or other threats are unable to reach corporate systems, negating the effectiveness of even sophisticated attacks.

“It’s exciting to see browser isolation technologies embraced by CDR respondents, in part because they’re designed to improve security without affecting the end user’s experience at all,” said Steve Piper, founder and CEO of CyberEdge Group. “We think that we’ll all be hearing more about the importance of this type of technology in the future.”
