]]> Bad Rabbit Ransomware Automatically Mitigated by SonicWall Capture Advanced Threat Protection

On Tuesday, Oct. 24, a new strand of ransomware named Bad Rabbit appeared in Russia and the Ukraine and spread throughout the day.

SonicWall Capture Labs threat researchers investigated Bad Rabbit and the proficiency of the SonicWall Capture Advanced Threat Protection (ATP) sandboxing service against the previously unknown ransomware. Analyzing three different Bad Rabbit samples, the multi-engine Capture ATP successfully stopped all three attacks.

The SonicWall Capture ATP sandboxing service is designed to provide real-time protection against new strains of malware even before signatures are available on firewalls.

In addition, the SonicWall Capture Labs released signatures to protect customers against Bad Rabbit malware. These signatures are available to SonicWall firewall customers with an active Gateway Security subscription (GAV/IPS) and are applied automatically. More info here.

CSSI is a SonicWall Partner and has many customers with SonicWall firewalls and active security subscriptions. CSSI technicians have training in SonicWall networking and have Certified SonicWall Security Administrator (CSSA). Contact us today to protect your business from ransomware!

]]> Recently we’ve seen an influx in spam emails containing PDF documents. The PDFs contain a link, which when clicked  takes the victim to a website prompting them for usernames and passwords. By entering the username and password, the victim is giving the thieves their email password – compromising the account. This type of attack is called phishing.

Phishing
noun
the fraudulent practice of sending emails purporting to be from reputable companies in order to induce individuals to reveal personal information, such as passwords and credit card numbers.



What Can Be Done?

Please be on guard for emails with PDF attachments, especially those from unknown senders. Even if the email comes from a trusted sender, that person’s account may be compromised. Above are some common templates for gathering credentials.

Additionally, some email systems (Office 365, G Suite) can be configured to warn users whenever a PDF attachment with a link is included in an email, as seen in the Office 365 rule below.
