One of the world’s largest producers of aluminum is currently operating the old-fashioned way—manually. Late Monday night, Hydro, an Oslo, Norway-based aluminum manufacturing company fell victim to a LockerGoga ransomware attack. It’s the same one (1) that attempted to extort money from a French engineering firm in January. LockerGoga distributes the ransomware by using victims’ own Active Directory against itself.
Here’s where it all got started
The ransomware was launched at one (1) of the Hydros U.S. plants, then rapidly spread throughout its global operations. As Norway’s second largest company, and with over 35,000 employees in fifty (50) different countries, Hyrdros staffers had to turn back the clock and rely on manual processes to manage orders and shipments, and monitor smelters scattered throughout the world. Yes, they put pen to paper.
Several automated product lines and extrusion plants were shut down, which resulted in customers from several industries waiting at the curb for their aluminum shipment to arrive. Several automakers were unable to manufacture aluminum automotive components.
Kripos, which is Norway’s National Criminal Investigation Service, learned about the attack Tuesday morning through the country’s Joint Cyber Coordination Center. Kripos has been liaising with Europol, the EU’s law enforcement intelligence agency, even though Norway isn’t a part of the EU. However, their 2001 agreement with the EU enables it to work with Europol.
How LockerGoga works
Thanks to LockerGoga, Hydros’ own Active Directory basically attacked itself. It was a three-pronged approach: obtain domain credentials, identify targets by querying Active Directory, which maintains information about users, apps, servers, endpoints, et al., then move through the network and self-propagate itself until the entire company is locked down.
The Hydros website was down for over twenty-four (24) hours, and it’s still uncertain how long it will take to restore stable IT operations. Most of its IT systems have been down at some point since Monday night, but Hydros reports that power plants operating on IT systems unaffected by the attack are running normally. Since the attack, Hydros has been using Facebook for its primary means of communicating. And the hackers didn’t receive a dime of ransom. Hydros did what many do—rely on its backups.
Why pick on Norway?
Cyber threat-wise, Norway has had a rough few months. Unless hackers resent the fact that the country of just over five (5) million runs away with most of the gold medal at each Winter Olympics, it just happens to be its time in the cyber security nine (9) circles of hell. And it comes at a bad time for Hydros; over a year ago, its plant in Brazil had to shut down amid claims that a spill was destroying the environment. It resulted in its shares falling almost forty percent (40%). In early trading Tuesday morning, its shares dipped another 3.4%.
In February, it was uncovered by cyber security investigators that hackers working with the Chinese government had breached the network of Norwegian software firm Visma. They wanted to steal intellectual property and client information. The attack, known as Cloudhopper, targets software providers and technology services firms.
Lesson to be learned?
Educate your employees. While they’ve yet to confirm it, Hydros suspects that one (1) of its 35,000 employees was successfully phished. Somebody opened a strange, but apparently tempting, email. That’s all it takes.
