Prevent Ransomware Attacks With Email Security

Know Your Risks

The Problem with Ransomware

Ransomware can have an overwhelming impact on businesses of all sizes and across all industries. Sensitive data such as, personal and corporate data, financial and healthcare records, network share files, can be taken hostage by ransomware – which can result in a halt in businesses, slow down in productivity, and, potentially, set an entire organization up for failure.

Detecting and preventing ransomware is extremely difficult because:

There can be multiple threat vectors attacking the organization in several different ways, making the chances of success higher.
Email is a delivery mechanism of choice for ransomware and phishing attacks have become increasingly sophisticated. CryptoLocker, Petya, Locky and TeslaCrypt are some famous examples where phishing was used as a means to deliver ransomware
Legacy systems leave organizations unequipped to deal with these threat types.

Reconnaissance

Initially, an attacker will utilize social engineering to gather information about the potential victim(s).

Delivery: Phishing Email

An attacker uses phishing emails to target employees. These phishing emails are hard to detect, because they’re created to look like they come from a trustworthy sender, but link to or contain malicious content.

Exploitation and Infection

It only takes one click. Once a malicious file or link is opened, the attacker runs exploits on the targeted network and installs malware.

Lateral Movement

Once they’re in the system, attackers can move laterally to other systems and accounts in order to gain more leverage: whether that’s higher permissions, more data, or greater access to systems.

Data Exfiltration

After gaining a foothold, the attackers can continue to carry out their objectives which may include data exfiltration.

Impact

The impact of ransomware can be overwhelming for businesses. Sensitive data can be taken hostage and organizations can be locked out of their business critical systems. Either way, the financial, reputational, and regulatory impact is significant.

Attacks On The Rise

Phishing attacks can lead to ransomware.

Phishing attacks, the top delivery vehicle for ransomware, are one the rise. Why? Cybercriminals are becoming increasingly sophisticated. They’re evading detection patterns and taking advantage of the information users share on social media to create more authentic email templates – making it difficult for employees to detect phishing attempts.

Most legacy phishing tools largely rely on previously known attack signatures to stop threats. As a result, organizations today learn about these attacks when it’s too late.

The Tessian Advantage

How Tessian Prevents Ransomware with Human Layer Security

Phishing Detection & Prevention

Defender’s behavioral intelligence leverages at least 12 months of historical data that includes the company’s emails, company network, as well as Tessian’s Global Threat Network, to detect all indicators of inbound email attacks, including malicious intent in ransomware.
