Despite the recent years’ NSA spying revelations, numerous international malware attacks and North Koreas’ hacking of Sony Pictures, maritime cyber-security is not an issue at the forefront of many ship-owners and managers minds.
However, whilst the maritime industry might not seem a likely target, reports of successful cyber-attacks are not unknown. Take, for example, the Port of Antwerp, where hackers working with a drug-smuggling gang repeatedly breached digital tracking systems to locate containers holding large quantities of drugs. They then dispatched their own drivers to retrieve the containers ahead of the scheduled collection time.
After two years, the operation was eventually shut down and there were no major repercussions for the Port of Antwerp or the companies involved. However, according to security experts at Trend Micro, these companies were extremely fortunate. Using the same techniques, it would not be difficult for criminals to cause chaos at sea. By simply accessing and manipulating a vessel’s AIS, hackers could prevent ships from providing movement information, cause AIS users to detect vessels in false locations or make “phantom” structures or vessels appear.
Other examples of an industry at risk include a drilling rig being hacked and forced to suspend operations, as well as a container line’s entire database of cargo information, including container number, location, place of origin, being erased. Furthermore, instances of maritime and offshore companies that have potentially fallen victim to cyber-attacks may be under-reported, as companies may fear appearing to have allowed confidential information to be compromised.
Adopting good “cyber-hygiene” will dissuade opportunistic attacks and prevent accidental security compromises.
Developing and implementing such policies will require a top down approach within a company. At the most basic level a company should:
- Set strong user access controls
- Set strong network access controls
- Perform regular backups
- Keep software up to date
Training employees on how to recognise cyber-attacks and implementing policies on computer hard-ware usage, particularly the use of USB memory sticks, are further steps a company should consider.
Doing what you can to secure your networks and taking the time to integrate cyber-security into your risk management and crisis communications procedure, are the two most strategic things you can do to ensure you can respond effectively to maritime cyber-security threats and in doing so, protect your reputation as a secure service provider.
there has not been a single, dedicated hacking attack against a vessel at sea by malicious actors. While there have been rumors – specifically one from an American telco provider in 2016 – that hackers have teamed up with pirates to track high value cargoes, there has been no firm evidence.
Equally, the dire warnings from some quarters of ships having their navigation systems hacked so they can be directed to ports where pirates or criminal gangs could then ransack them have so far proven to be little more than interesting worst-case scenarios. Once you begin to dig in to the logistics of such a criminal enterprise, it quickly falls apart. After all, it requires the use of a pirate-friendly port or harbor deep enough to accommodate the hijacked vessel as well as a significant number of personnel to offload cargoes, crew and so on.
The traditional method of attacking a vessel at sea and then holding it to ransom, or simply kidnapping crew, has so far proven more attractive to pirates in both East and West Africa. Indeed, in countries such as Nigeria, there’s little need for such efforts. Vessel arrivals and cargoes carried are listed on a weekly basis in the local papers.
However, it is entirely possible that organized criminal gangs can and will team up with hackers in order to locate high value cargoes at container terminals, for instance. Drug smuggling gangs have been using European ports and cargo terminals for years, as recent arrests in Antwerp and other E.U. ports confirm.
What has been noted in the maritime domain, however, is a rise in spear-phishing of vessels at sea. This has become an increasing problem and prompted the U.S. Coast Guard – widely seen as being at the forefront of maritime cyber security – to issue a series of warning and advice notices in July 2019. They warned that emails purporting to have come from the U.S. Port State Control authority were being sent to ships and disseminating malware throughout vessel systems. They reported that a merchant vessel bound for the Port of New York began to experience “a significant cyber incident impacting their shipboard network.”
An investigation found that, “although the malware significantly degraded the functionality of the onboard computer system, essential vessel control systems had not been impacted.” Additionally, and perhaps unsurprisingly, they noted that the vessel was, “operating without effective cyber security measures in place, exposing critical vessel control systems to significant vulnerabilities.”
While incidents like this are a genuine cause for concern, more commonly, the maritime domain has seen malware introduced into ship systems by crew and third party providers by accident. While these incidents have been, in some cases, hugely expensive to put right – any delay to a vessel costs money – they have so far fallen short of the scare stories suggested by some parties.
This is not to dismiss or minimize the threat of an actual, focused attack by an Advanced Persistent Threat (APT) group on a shipping line or vessel. It could happen. Indeed, it probably will. But it hasn’t happened yet for a number of reasons, the main one being, Why? Why attack a ship? If we assume that most cyber attackers are criminal rather than terrorist or hacktivist, then the motives for attacking a ship at sea begin to fall away; there simply isn’t any profit in it, and return on investment is important to cyber criminals. It’s like mugging a bank teller rather than emptying the cash drawer.
Vulnerabilities on board vessels exist, and often nobody knows anything about them. A recent investigation by Pen Test Partners noted that, unknown systems can be prevalent on board ships. “In every single [nautical pen] test to date we have unearthed a system or device, that of the few crew that were aware, no one could tell us what it is was for,” said Andrew Tierney, researcher with Pen Test Partners, writing in a blog on October 14. “In other scenarios an undocumented system or device would be considered a malicious implant. In maritime cyber security it’s business as usual.”
In one case, a monitoring system was uncovered whose purpose was not known – although it was connected to the main engine. Fleet management had no record of its purchase or installation; all hardware was unlabeled. It had been installed by a third party with whom a commercial arrangement had stopped several years ago, Tierney said in an article by Threat Post.
Clearly, there’s an ongoing need for shipowners to conduct robust cyber security assessments on their vessels, something the U.S. Coast Guard strongly urges all companies to do, whether internally or by bringing in specialist cyber security companies who understand the maritime domain.
While cyber risks on the water remain a concern, the ongoing, real threat is and will always be found at a company’s head office. How a company deals with that will decide what an attacker does next. Outside the realm of hacktivism, criminals are looking for a payday, and that means they’re going to be looking for any vulnerability which can give them access to company finances.
In the last few years, I’ve seen numerous reports of highly specific and convincing email fraud attempts against shipping companies, ports and ship brokers. In several instances, the hackers have infiltrated a company’s systems and then sat dormant, often for months, waiting for their opening. In one case, this involved sending spoofed emails to a client and redirecting payment of hundreds of thousands of pounds to the hacker’s bank accounts. Fortunately, thanks to quick-thinking staff, the fraud was discovered and the banks and police were able to stop the transfers. But this isn’t always the case.
Directed attacks remain a significant threat to any company, regardless of the business sector, and maritime is no different. Shipping has so far managed to avoid the headline-grabbing attacks such as the $4.2 million stolen from an Oklahoma pension fund, or the $47 million initially stolen from networking firm, Ubiquiti in 2016, but the sector remains highly exposed due to a number of factors.
The Push for Efficiencies
As the maritime industry embraces digitization and the efficiencies and cost savings that come with it, security can often be taken for granted. Unfortunately, as those systems evolve, so do attackers. Their methods become more advanced and the paydays bigger. For example, phishing emails have been with us since the dawn of email. The question is how your company deals with them. There are a few questions you should ask yourself, or senior management:
- Does your company have a dedicated Chief Information Security Officer (CISO)?
- Are you a small organization reliant on third party software and consultants?
- Has your administrative staff been trained to recognize a phishing attempt?
- Are they aware of the risks of social engineering?
- Are they regularly updated with the latest threats and attacks in your sector?
If the answers to those questions are all “Yes,” then here’s another: Does this extend to your crew on the water? Do your vessels employ specific measures to counter and combat attack or contamination?
Deep Fakes are Here
The persistent threat to most companies is the Business Email Compromise (BEC) or CEO Fraud. The good news is that it’s relatively easy to mitigate in most companies. The bad news is that it’s becoming highly sophisticated, thanks to “deep fakes.”
In September 2019, it was reported that a gang of cyber thieves had managed to steal $243,000 from a U.K. energy firm in a complex BEC attack that used an AI-generated voice of the company’s German parent firm’s CEO to authorize the transfer of funds. During the course of just three phone calls, the AI was convincing enough for the criminals to pull the fraud off. And, as the media reported at the time, “After the transfer, the funds were moved to Mexico and then to other countries, making the funds harder to track. No suspects have been identified.”
How would your company deal with such an incident? Are large financial transfers subject to face-to-face scrutiny with senior management? Well, they should be. You can no longer rely on a phone call or email to confirm that a transfer of funds has actually been authorized by senior management. Nor should you.
The threats to vessels at sea are more easily apparent. BIMCO has noted a number of incidents where malicious software was introduced to ship systems by accident, often by third parties contracted to check or even update specific bridge equipment, but crew introduction remains the more obvious route. Again, this is easily countered by enforcing strict protocols; blanking off USB ports and ensuring no crew equipment is plugged in to any ship computer systems being the most obvious. Again, training courses and refreshers should be offered to all crew, as well as more practical software protection.
Following the reported spear-phishing incidents this summer, the U.S. Coast Guard suggested that basic, cyber security practices be adopted by ships. These include:
- Implement network segmentation.
- Create network profiles for each employee, require unique login credentials and limit privileges to only those necessary
- Be wary of external media
- Install anti-virus software
- Keep software updated
Basic, common sense moves designed to make breaking in to or disrupting your ship systems a little harder. Yet it’s surprising how few vessels adopt even these recommendations.
Mitigate and Educate
The good news is that over the last few years, maritime cyber specialists have entered the market and maritime cyber insurance policies have matured. Templar Executives, a U.K. cyber security specialist, teamed up with Wärtsilä to create the International Maritime Cyber Centre of Excellence (IMCCE), which consists of the Templar Cyber Academy for Maritime (T-CAM) and a Maritime Cyber Emergency Response Team (MCERT).
Through its Cyber Academy, Templar now offers training for companies operating in the maritime domain, from the C suite and administrative staff to crew and port officials, while the MCERT, with its 24/7 operations center, is intended to share information on new attack vectors and prevent as many incidents as possible. As a result, it’s now being picked up by marine insurers, with Lampe & Schwartze in Germany partnering with Templar to launch a new Ship Owners Marine Cyber Cover.
The hope is that moves such as this will lead to companies reporting cyber intrusions and attacks in a timely manner. At present, there are no firm figures for maritime cyber security incidents; shipping companies are, in general, loathed to admit to them for a variety of commercial reasons. Anonymous reporting will certainly make that easier, as companies such as CSO Alliance hope with their Maritime Cyber Alliance. However, speed is key. It’s crucial that a company under attack share the information in order to allow others in the sector to bolster their own defenses. In this case, sharing is definitely caring.
The Innocent Bystander
Of equal concern is the potential knock on effect from a wider malware attack. Few people in the maritime domain will be unaware of the NotPetya incident that affected Maersk in 2017. To call it massive would be an understatement. More worryingly, Maersk was simply unfortunate collateral damage in an attack that spread around the world and saw the company forced to rebuild its network of 4,000 servers and 45,000 PCs at a cost running into hundreds of millions of dollars.
The financial blow alone should be a salutary warning to most companies, but the fact that it happened as part of a domino effect should be more sobering. Your company doesn’t have to be directly targeted to be impacted.
Threat mitigation is good, but threat prevention is always better. These days, there are few excuses for any company not to adopt a robust cyber security policy for its land- and sea-based operations, particularly given the scale of the threat and its financial implications.
As the shipping industry begins to look seriously at the prospect of autonomous vessels, these same problems persist and insurance underwriters are already taking note. It will be interesting to see how the industry adapts to the challenges posed.
