Cybersecurity “Flash” Warning for Construction and Manufacturing Businesses

Mar 24, 2021

On March 23, 2021, the FBI’s Cyber Division issued a “Flash” warning for several business sectors, including industrial, commercial, manufacturing and construction businesses.  The FBI is warning that a strain of ransomware, known as “Mamba,” has been used to weaponize a widely-used encryption software known as DiskCryptor.  Mamba works through the open-source DiskCryptor program to encrypt a company’s operating system and demand ransom payment.  This new ransomware attack is a threat to any business which employs DiskCryptor, specifically manufacturing and construction companies.

What Should I Do?

If your company utilizes DiskCryptor, the FBI suggests a number of recommendations to mitigate and ward off any ransomware attack.  Most of these suggestions fall within the guidelines of proper cyber hygiene, and include (but are not limited to) the following:

  • Regularly back up data, as well as copies of data;
  • Segment your network;
  • Request administrator credentials to install software;
  • Implement a recovery plan;
  • Patch operating systems, software and firmware as soon as patches are released;
  • Use multifactor authentication;
  • Regularly change passwords;
  • Audit user accounts;
  • Install and update anti-virus and anti-malware software;
  • Only use secure networks and avoid public Wi-Fi; and
  • Train users and raise awareness.

Even if you do not use DiskCryptor, taking these actions will help mitigate any future ransomware attack, regardless of origin.
