Ransomware

City in North Carolina affected by Ryuk ransomware.

In March 2020, the city of Durham, North Carolina, was affected by Ryuk ransomware. The ransomware instance was planted in the city’s network via a phishing email and targeted the 911 call center and the city’s fire department.

As soon as the incident was discovered, Durham's officials temporarily disabled all access into the network for the Durham Police Department, the Durham Sheriff’s Office, and their communications center. Though there has been no evidence of any data being stolen, officials have instructed residents to keep an eye out for any emails claiming to be from the city. The Ryuk ransomware strain has been identified to be disastrous, as it 's designed to specifically infect crucial assets and resources in each targeted network. Recent victims of ransomware include US-based Fortune 500 company E MCOR, North America’s leading railroad company; RailWorks Corporation; and French ISP and cloud provider Bretagne Télécom.

How ManageEngine can help.

Exchange Reporter Plus provides a host of reports that can help you locate suspicious emails, both sent and received, based on keywords in their subject or body. Often times, these malicious emails appear to be valid, tricking users into opening the emails and clicking on links embedded in them, which can cause serious damage.

With Exchange Reporter Plus, you can locate emails based on:

  • Messages by subject keyword. Use reports to identify particular keywords in the email subject lines.
  • Messages by body keyword. Identify all the messages in your mailbox that have a particular keyword in the body of the email.
  • Attachment name. Get a report of all emails in your mailbox that have an attachment with a specific name. With the names of the malicious files, you can take the necessary steps to stop email-bound threats.
  • Attachment type. Based on an attachment’s file extension, you can spot malicious software.
  • The number of emails received from a specific domain, sender, department, or external email address. Get reports on all incoming emails from an external email address, a blacklisted sender or domain, or a specific department.

In addition, ManageEngine O365 Manager Plus provides an advanced Office 365 mailbox content search capability that identifies phishing emails by analyzing internet message headers, subjects, attachments, and bodies of emails. With this feature, you can identify senders' email addresses, the platform used by the attackers, and the servers the emails passed through.
