The Ransomware Files, Episode 4: Maersk and NotPetya

Malware Disguised as Ransomware Nearly Sank Logistics Giant Maersk
The Ransomware Files, Episode 4: Maersk and NotPetya

What if malware disguised as ransomware destroyed every copy of a company's Active Directory except for one?

That's exactly what happened to global shipping and logistics company Maersk on June 27, 2017. Maersk was one of dozens of organizations crippled by the NotPetya malware in one of the strangest and most devastating global cyberattacks.

Gavin Ashton was Maersk's identity and access management service owner at the time.

"We talk about milestones and project plans and three-, five-year plans," Ashton says. "And the thing about ransomware, or extortion, or whatever you want to call it these days, is it doesn't really care about any of that. It could literally strike this afternoon. That was our wake-up call."

Bharat Halai was Maersk's former head of identity and access management. The attack knocked out all of Maersk's copies of Active Directory. Halai's quick thinking uncovered the last remaining uncorrupted copy in Lagos, Nigeria, which had experienced a wide area network outage.

"I asked the head of IT and said, 'Can you just make sure you call every single site and ask them if any of them had a WAN outage at any point since the NotPetya event or before?'" Halai says. "Fortunately, the head of IT came back and said, 'Yes, we have one site that has had a WAN outage before the 27th of June.' I thought, 'Great.' Now, first thing to do, is back that baby up quick, quick before it goes."

In this episode of "The Ransomware Files," Ashton and Halai explain how the dedication and tenacity of the team at Maersk brought the company back from an IT systems meltdown. They also explain how they rectified weaknesses in Maersk's identity and access management systems that had caused NotPetya to spread so quickly.

"The Ransomware Files" is a podcast miniseries available on Spotify, Apple Podcasts, Google, Audible, Stitcher and more. I'm speaking with those who have navigated their way through a ransomware incident to learn how they fought back and what tips they can pass on to others. No ransomware infection is ever welcomed. But there's invaluable knowledge gained. There should be no shame in getting infected, and it's important to share the lessons.

If you enjoyed this episode of "The Ransomware Files," please follow it on a podcast platform and leave a review. Also, the show has a Twitter handle, @ransomwarefiles, that tweets news and happenings about ransomware.

If you would like to participate in this project and tell the information security community about your organization's brush with ransomware, please get in touch with me at jkirk@ismg.io or direct message me here on Twitter. I'm looking for other people, organizations and companies that can share their unique experiences for the benefit of all until ransomware, hopefully, becomes a thing of the past.
