Maritime Cyber Security & Threats March 2020 Week Four

In the above collection we see malicious actors attempting to use vessel names to try to spoof companies in the maritime supply chain.   This week we observed a large percentage of these malicious emails attempting to deliver Windows trojan malware.  Some of the new Vessel names used this week include “MV THOR MADOC” which and we see “MT Ocean Chemist” again this week among others.

An email was observed attempting to impersonate a “Maersk” employee using a subject line of “Maersk New Shipping schedule details due to COVID-19- Shipment notification.” The sender includes “Maersk” and “COVID-19” in the subject line to trigger the recipient to believe the message is urgent and related to the current CoronaVirus Pandemic.

Analysis reveals that the malicious email was sent from an illegitimate domain – infintetradeltd[.]com.  The text content of the website infintetradeltd[.]com is “codermails[.]in, Bulk Automated Mailing Server Installer codermails[.]in Bulk Emailing Made Easy!” which further indicates its illegitimacy.  Impersonating Maersk is a common tactic and Red Sky Alliance has seen a significant increase in malicious emails related to the current COVID-19 Pandemic.

The target of the malicious email belongs to Royal Precision Tools Corporation in Taiwan.  This company generates “spindle designs born of technical expertise.” Due to the fact that the company is located right outside of China, they are likely to open an email pertaining to COVID-19.

The message contains an attached .ace file identified by Microsoft AntiVirus engine as the Trojan:Win32/Bluteal!rfn malware.[1] It executes commands from a remote malicious user, effectively compromising the affected system.[2]  The email message states that the sender will be cancelling a shipment, but then tells the recipient to check the attached filed to advise if the sender should proceed.

This week Red Sky Alliance sees multiple emails attempting to leverage COVID-19 (CoronaVirus Disease 2019) using the subject lines containing terms related to the Pandemic, specifically in the maritime industry.  Since January 2020 , analysts have observed emails referencing COVID-19 to entice users to open the emails urgently. Many companies are sending out announcements regarding the outbreak which acts as camouflage for attackers.   Another reason users open these emails is because many people are expecting to receive an email from one of its vendors/customers regarding COVID-19.

In another malicious email, with subject line “COVID-19 SUSPECTED CREW /VESSEL.” analysts see the World Health Organization being leveraged to spread malware. Although the message body is redacted, there are two malicious attachments.  One is an MS Word document and the other is and MS Excel spreadsheet. Both were detected as malicious by AntiVirus software.  The sender and recipient email addresses are shown as alias’ but otherwise appear legitimate.

The attached MS Word filename is the exact same as the subject line listed above (COVID-19 SUSPECTED CREW /VESSEL.doc).  Microsoft AV indicates both of the malicious attachments exploit CVE-2017-11882.  Malware of this family consists of a .doc or .docx document containing a script that can be run in Microsoft Word (Visual Basic for Applications). Interestingly, the Word document shuts down Windows defender, but the Excel spreadsheet is detected and quarantined immediately.

The more convincing an email appears, the greater the chance employees will fall for a scam.  To address this residual risk, software-based protection should be treated as one constituent of a wider strategy that also encompasses the human-element as well as organizational workflows and procedures.

It is imperative to:

• Train all levels of the marine supply chain to realize they are under constant cyber-attack.
• Stress maintaining constant attention to real-world cyber consequences of careless cyber practices or general inattentiveness.
• Provide practical guidance on how to look for a potential phishing attempt.
• Use direct communication to verify emails and supply chain email communication.
• Use Red Sky Alliance RedXray proactive support, our Vessel impersonation information and use the Maritime Black Lists to proactively block cyber attacks from identified malicious actors.
