GREYCORTEX Protects against WannaCry

GREYCORTEX is happy to report that MENDEL, our network traffic analysis solution, affirmatively detects infection by the WannaCry ransomware, its possible variants/clones, and protects users more effectively than rule-based detection tools alone.

Because GREYCORTEX MENDEL uses advanced artificial intelligence, machine learning, and data analysis to identify network anomalies, it easily identifies threats like WannaCry, allowing network security teams to take rapid action and stop threats before they do damage.

In the case of WannaCry, GREYCORTEX tested the ransomware in our malware lab. It was found to engage in aggressive and anomalous practices, like port-scanning behavior on an SMB port (445), attempting to connect to over 4000 devices in 175 countries across the Internet in five minutes, and downloading TOR network software. All of these behaviors were identified by MENDEL’s advanced network behavior analysis.

MENDEL users are better protected from malware like WannaCry and its variants/clones than users of firewall, IDS, or other rule-based security solutions alone. Rule-based security solutions require a known malware signature in order to create a rule. This means an attack must happen before the signature of the attack can be added as a rule. MENDEL doesn’t need a signature to identify the attack. It’s network behavior analysis features detect the attack’s symptoms before it harms the network. This means security teams have the peace of mind to know that should an attack happen, they will see it, and be able to stop it before it does damage.

If you are concerned about malware attacks, either from WannaCry or from other ransomware or malware, you may benefit from a 30 day Proof of Concept (PoC) from GREYCORTEX. During the PoC, MENDEL automatically learns your network to identify threats which may exist, including ransomware which is lying dormant in your network, or unpatched applications, which may leave you vulnerable. Do not hesitate to contact your network security professional, or GREYCORTEX  directly to arrange a PoC.
