In the first half of the year, manufacturing companies were the most susceptible to cyber threats: their ICS computers accounted for about one third of all attacks, according to the Kaspersky Lab report “Threat Landscape for Industrial Automation Systems in H1 2017”. The peak of attackers’ activity was registered in March, after which the proportion of computers attacked gradually declined from April to June.
During the first six months of the year, Kaspersky Lab products blocked attack attempts on 37.6% of ICS computers from which we received anonymized information, totaling several tens of thousands. This figure was almost unchanged compared to the previous period – it is 1.6 percentage points less than in the second half of 2016. The majority of them were in manufacturing companies that produce various materials, equipment and goods. Other highly-affected industries include engineering, education and food & beverage. ICS computers in energy companies accounted for almost 5% of all attacks.
Distribution of ICS computers attacked by industry, H1 2017
While the top three countries with attacked industrial computers - Vietnam (71%), Algeria (67.1%) and Morocco (65.4%) remained the same, researchers detected an increase in the percentage of systems attacked in China (57.1%), which came fifth, according to the data released by Kaspersky Lab. Experts also discovered that the main source of threats was the Internet: attempts to download malware or access known malicious or phishing web resources were blocked on 20.4% of ICS computers. The reason of the high statistics for this type of infection lies in interfaces between corporate and industrial networks, availability of limited Internet access from industrial networks, and connection of computers on industrial networks to the Internet via mobile phone operators’ networks.
In total, Kaspersky Lab detected about 18,000 different modifications of malware on industrial automation systems in the first six months of 2017, belonging to more than 2,500 different families.
In the first half of the year the world has been facing a ransomware epidemic, which also affected industrial companies. Based on the research from Kaspersky Lab ICS CERT, the number of unique ICS computers attacked by encryption Trojans increased significantly and had tripled by June. Overall, experts discovered encryption ransomware belonging to 33 different families. Most of the encryption Trojans were distributed through spam emails disguised as part of the business communication, with either malicious attachments or links to malware downloaders.
The main ransomware statistics from the H1, 2017 report include:
“In the first half of the year we've seen how weakly protected industrial systems are: pretty much all of the affected industrial computers were infected accidentally and as the result of attacks targeted initially at home users and corporate networks. In this sense, the WannaCry and ExPetr destructive ransomware attacks proved indicative, leading to the disruption of enterprise production cycles around the world, as well as logistical failures, and forced downtime in the work of medical institutions. The results of such attacks can provoke intruders into further actions. Since we are already late with preventive measures, companies should think about proactive protective measures now to avoid ‘firefighting’ in future.” says Evgeny Goncharov, Head of Critical Infrastructure Defense Department, Kaspersky Lab.
