Norsk Hydro – A Ransomware Case Study

by

Norsk Hydro, the Norwegian aluminium manufacturer were hit by a ransomware attack in March 2019. The company is one of the largest aluminium producers of its kind with smelting plants and factories in 40 countries being managed by their 35,000 employees.

The ransomware attack impacted on their production in Europe and the US which resulted in the company having to revert to manual operations to manage their industrial control systems albeit on a much slower basis than normal whilst they battled against the ransomware attack.

Parts of the business were however still operational which allowed a degree of production to still be maintained.The stoppage of the primary metal and rolled products had some operation impact from a business interruption perspective.

The CFO announced that the ransom bitcoin demand had and will not be paid as they attempted to restore the company’s software and preserve their data.

The cause of the cyber attack was as a result of an employee opening an infected e-mail from what was thought to be a trusted customer which allowed the hackers to gain access to their IT infrastructure and put in place the ransomware virus.This was an example of an Advanced Persistent Threat (APT).

The type of ransomware is thought to have been LockerGoga which enables hackers to encrypt computer files very quickly which are then locked with a ransom demand then being made to release them. The hackers also threatened to increase the ransom should their be any be any delays in paying to add further pressure to the situation.

Norsk Hydro made three quick decisions which helped mitigate the attack:-

  • The CFO announced that the ransom bitcoin demand had and will not be paid.
  • Microsofts cybersecurity team ( Detection and Response Team know as DART)  were engaged to help restore the operation.
  • Norsk Hydro were very transparent about the attack and hosted daily webcasts and press conferences providing updates on the attack which does not normally occur.

A special team was build up in the coming weeks which helped the business re over and reconstitute its business operations . This helped remove the threat posed by the hackers and to understand the mechanism of the ransomware attack.

Norsk Hydro shared a video of how they dealt with the ransomware attack in their Toulouse plant.

The financial impact of the ransomware attack is through to be in the region of $70- 80M. NorskHydro also purchased a cyber insurance policy which is believed to date to have paid out $33M.

The Cyber Security Threats For 2020

by
Cyber Security Threats

Cyber Security threats are evolving all the time making it extremely difficult for business to combat this and it is now even more important to have in place the appropriate protections to keep them safe from hackers.

The same core cyber security threats still exist but these are becoming more sophisticated and difficult to trace and prevent.

Ransomware   

Ransomware is now not just used as a scatter gun approach but is now being more targeted at businesses where ransom demands are now much larger than before. The decision now becomes to pay the ransom in order to obtain the decryption key to mitigate the interruption to the everyday operation of the organisation or to hold out and rely on the back-ups in place that hopefully would not be corrupted. New strains of ransomware are also appearing and becoming increasingly difficult to repel.

Phishing Attacks

These types of threats remain prominent and despite an increase in training by companies to help employees spot such attacks, commonly sent via e-mails, success is high for hackers still reaping rewards.

Internet of Things

The interconnection of devices is increasing at an alarming rate with all aspects of life now being connected from the office to the home . The concern is that people are more reliant on this and this provides greater opportunity for hackers to access a network and cause disruption.

The Supply Chain

The supply chain of any business is in many cases fundamental to its operation where this be the supply of technology or the provision of non IT services. The cyber security of such entities is in a number of cases not as robust as the principal business and should their IT be compromised this can lead to a hacker gaining access up the line.

The Insider Threat

This remains a prominent threat and is to an extent still hard to predict as this is determined by human nature. Even with the most sophisticated firewalls in place if an employee is determined enough to steal data they will succeed. It will be interesting to see how the Morrisons case develops which laid down that businesses are vicariously liable for the actions of employees in the event of a data breach of their employees personal data.

Artificial Intelligence  ( AI)  

AI as it is know is perhaps the newest of the cyber threat vectors that now exist and is the most unknown but potentially the one that could cause the most disruption. It is also the most difficult to defend against. Deep Fake videos are a fast developing area where a believable video conference call from what is thought to be the CEO could have been created by AI , this could lead to misinformation being relayed within the company and impact business decisions.

What is the CCPA ?

by
CCPA

The California California Consumer Privacy Act (CCPA ) is a new consumer protection law which comes in effect from 1st January 2020 and is yet another sign that data protection is now taken very seriously. This follows closely in the steps of the General Data Protection Regulations ( GDPR) which were launch in May 2018.

Who does this apply to ?

  • This law is applicable in the state of California where organisations carry our business that involves collecting and processing the personal information of individuals.
  • Where an organisation has gross revenues of over $25,000,000
  • If an organisation buys / sells at least 50,000 consumers personal records for commercial gain
  • If an organisation earns more than 50% of their revenue from the selling of a consumers personal records.

If all any of this criteria is met then the CCPA will be applicable and the business will have to adhere to these regulations.

What are the consequences of non- compliance?

Should this be the case it is possible that the business could face the following penalties :-

  • Civil Penalty up to $7,500 for each intentional violation and $2,500 for other violations
  • In addition to this  the victims of a data breach may obtain $100 to $750 per consumer, per incident.

The importance of how a business manages its data is therefore of the utmost importance in order that these regulations are complied with and to avoid any penalties that stem from a breach of these regulations.

Some guidelines to the management of data 

  • Ensure that all employees are updated with this legislation and carry out training as applicable.
  • Ensure that all processes and procedures are aligned to comply with the new legislation and if not introduce new ones to cater for this.
  • Carry out a review of cyber security within the organisation and implement upgrades and improvements where necessary in order to mitigate a possible data breach.
  • Where necessary bring into line privacy notices and policies on websites and other public facing forums.

The protection of data is becoming a core value within businesses as in the event of a data breach the costs to manage this and the impact on their reputation can be severe.

Manufacturing – Cyber A Real Threat

by
Manufacturing

The manufacturing industry is becoming a prime target for hackers where their technology is being compromised resulting in significant disruption within this sector.

Make UK , the Manufacturers Organisation recently carried out a cyber security resilience survey in the UK which demonstrated varying degrees of preparedness by manufacturers.

https://www.makeuk.org/insights/publications/2019/09/06/cyber-security-and-manufacturing

The highlights of the report were as follows:-

  • 60% of manufacturers indicated that they had been subject to some form of cyber security incident
  • 41% of their customers had requested evidence of the robustness of their cyber security processes and procedures
  • 31% of manufacturers were also asked this question within the supply chain

IBM’s 2019 Global Threat Intelligence Index showed that 10% of all attacks are aimed at the manufacturing sector.

Cyber Risk 

As with most business digital transformation is underway but with this brings new vulnerabilities and threats which need to be managed. For the manufacturing sector achieving the optimum production rates is vitally important and one of the ways in achieving this is through digitisation and a greater reliance on connectivity throughout the organisation.

What are some of the main Cyber Threats in this sector?

  • The theft of intellectual property by a hacker
  • Ransomware attacks from malware
  • Phishing attacks through as a result of access via the industrial control system
  • Spam messages which when deployed on mass will impact on productivity and communications within the organisation.
  • The compromise of the firms website that may impact on their reputation should defamatory of controversial commentary be posted by a hacker.
  • Employees or customers being subject to identity theft where they have had their personal details accessed by a cyber attack. This could include bank and credit card information details that are then used to commit fraud or are sold on the dark web.

How can the sector help protect itself ? 

Cyber risk management plays an important role in combating the evolving and unpredictable cyber threats that exist and should be pro-active rather than reactive.

In tandem with this businesses in this sector would benefit from purchasing cyber insurance which provides coverage for financial loss caused as a result of unauthorized access of their computer systems. More important it also provides incident response services from an established vendor panel drawn up by insurers.

Irrespective as to how cyber threats are managed it important that this given the correct level of priority at board level so that the right attention and appropriate resources are utilized to protect the well being of the organization.

Artificial Intelligence – Helping Cyber Security

by
Artificial Intelligence

Artificial Intelligence (AI)  is now playing a significant role in helping to managing cyber risk. This was recently evident in the aftermath of the Nordsk Hydro ransomware attack where AI was utilised to identify further vulnerabilities.

This form of automative technology would seem to be a good match for managing the constant threats posed by hackers where new cyber attacks relentlessly attack computer systems and constant monitoring is required. Despite the automation basis there however still needs to be human involvement in this process.

How Does AI Work ?

Billions amounts of data is consumed by AI via machine learning and deep learning techniques. This makes it possible to improve and develop its cyber security bank of knowledge which ultimately provides a better understanding of existing and developing cyber risks.

AI utilizes reasoning in order to identify relationships cyber threats malware threats and dubious IP threats . This is then analysed in a very short period of time thus enabling users to respond and act on imminent cyber threats.

Where can Artificial Intelligence be used ?

  • Monitoring of computer systems
  • Predictive tool for new threats
  • Analysis of threats based on current activity
  • Monitor Human activity
  • Post data breach tool
  • Detection of viruses and malware

The Future 

Capgemini released a report last month “Reinventing Cybersecurity with Artificial intelligence”

https://www.capgemini.com/wp-content/uploads/2019/07/AI-in-Cybersecurity_Report_20190711_V06.pdf

The report revealed that 69% of organisations felt that AI will be necessary to respond to cyber attacks in the coming years. Telecoms in particularly were of the view that this would help mitigate the sizable losses already experienced in this sector. Many organisations are gearing up for testing the viability of AI and how it can help their cyber risk management processes. Budget provisions for this are being made as long term there are many  costs benefits in AI.

Artificial Intelligence is developing at a rapid rate and it is important that its application remains relevant to the cyber security sector as other industries also show an interest in this technology.

Ransomware Is Still A Major Threat

by
Ransomware

Ransomware still remains one of the main methods that hackers utilise to carry out cyber attacks on businesses.

New strains of viruses are emerging all the time one such type is Sodinokibi which is only three months old but has had a significant impact already. It is also know as Sodin and REvil and connected to a previous form of ransomware called GrandCrab.

It is beloved that the average ransom demand for Sodinokibi in May was $150,000 against $50,ooo for other forms of ransomware. The largest recorded to date is $500,000.

Furthermore according to a report by Coveware, an incident response company the average downtime from a ransomware attack during the first part of this year has increased from 7.3 days 9.6 days which is believed to be due to the impact of this new ransomware.

The use of  Sodinokibi is also on the increase so much that it now accounts for 12.50% of the overall market.

Attack Methods

Sodinokibi is a ransomware-as-service (RaaS) and is used to attack both businesses and consumers and use various attack methods that include the following:-

  • Acting as malicious spam
  • Phishing attacks
  • Malvertising
  • Exploitation  of vulnerabilities in Oracle

The Signs of this Ransomware Infection

The normal signs of a ransomware attack are displayed when a computer system has been compromised by Sodinokibi this being changes in the desktop wallpaper and the announcement of the attack by way of a ransom note.

https://www.zdnet.com/article/sodinokibi-ransomware-is-now-using-a-former-windows-zero-day/

How it Happens

Files are encrypted on local drives by an encryption algorithm renaming all files with a pre-generated pseudo- random alpha- numeric extension that can be up to eight characters in length. This type of ransomware appears to target files which are mainly media related.

It also has been found to delete shadow copies of back-up and disables the Windows Startup Repair tool which prevents users from fixing any system errors relating to the ransomware attack.

Sodinokibi is unique in that it does latch on to zero-day vulnerabilities and and allow a Sodinokibi ransomware attacker access to endpoints that it infects replicating tasks that administrators would normally carry out.

How to Try and Prevent an Attack

Creation of back-ups of data on an external drive or on the cloud

Ensure that updates are run on all computer systems and appropriate patching is carried out.

Reinforce training of staff so that they are aware of possible phishing attacks that might carry this ransomware.

Restrict the use administrative tools to the IT team

Disable macro on Microsoft Office products

Cyber Insurance

The purchase of cyber insurance can help manage and mitigate the impact of these form of attack. This type of policy will provide coverage for the investigation costs of such an attack, the cost of negotiating with the hackers and if need be the actual ransom itself.
