Uncovering Vulnerable Industrial Control Systems from the Internet Core
Industrial control systems (ICS) are managed remotely with the help of
dedicated protocols that were originally designed to work in walled gardens.
Many of these protocols have been adapted to Internet transport and support
wide-area communication. ICS now exchange insecure traffic on an inter-domain
level, putting at risk not only common critical infrastructure but also the
Internet ecosystem (e.g., DRDoS~attacks).
In this paper, we uncover unprotected inter-domain ICS traffic at two central
Internet vantage points, an IXP and an ISP. This traffic analysis is correlated
with data from honeypots and Internet-wide scans to separate industrial from
non-industrial ICS traffic. We provide an in-depth view on Internet-wide ICS
communication. Our results can be used i) to create precise filters for
potentially harmful non-industrial ICS traffic, and ii) to detect ICS sending
unprotected inter-domain ICS traffic, being vulnerable to eavesdropping and
traffic manipulation attacks
Security of internet protocol cameras - A case example
The interaction of consumer devices and the internet, especially in relation to security, has always been tenuous. Where it is in the best interests of companies to produce products that are cheap and accessible, these traits often go against that of security. This investigation undertakes an analysis of one such device - the DCS-930L internet protocol camera from D-Link. This camera is analysed for vulnerabilities, with an emphasis on those relating to authentication mechanisms. Several vulnerabilities are identified, and potential attacks based on these are discussed. Solutions or mitigations to these vulnerabilities are presented
Automated Dynamic Firmware Analysis at Scale: A Case Study on Embedded Web Interfaces
Embedded devices are becoming more widespread, interconnected, and
web-enabled than ever. However, recent studies showed that these devices are
far from being secure. Moreover, many embedded systems rely on web interfaces
for user interaction or administration. Unfortunately, web security is known to
be difficult, and therefore the web interfaces of embedded systems represent a
considerable attack surface.
In this paper, we present the first fully automated framework that applies
dynamic firmware analysis techniques to achieve, in a scalable manner,
automated vulnerability discovery within embedded firmware images. We apply our
framework to study the security of embedded web interfaces running in
Commercial Off-The-Shelf (COTS) embedded devices, such as routers, DSL/cable
modems, VoIP phones, IP/CCTV cameras. We introduce a methodology and implement
a scalable framework for discovery of vulnerabilities in embedded web
interfaces regardless of the vendor, device, or architecture. To achieve this
goal, our framework performs full system emulation to achieve the execution of
firmware images in a software-only environment, i.e., without involving any
physical embedded devices. Then, we analyze the web interfaces within the
firmware using both static and dynamic tools. We also present some interesting
case-studies, and discuss the main challenges associated with the dynamic
analysis of firmware images and their web interfaces and network services. The
observations we make in this paper shed light on an important aspect of
embedded devices which was not previously studied at a large scale.
We validate our framework by testing it on 1925 firmware images from 54
different vendors. We discover important vulnerabilities in 185 firmware
images, affecting nearly a quarter of vendors in our dataset. These
experimental results demonstrate the effectiveness of our approach
Improving the National Cyber-security by Finding Vulnerable Industrial Control Systems from the Internet
Teollisuusautomaatiojärjestelmiä, joita käytetään muun muassa voimantuotannon, sähkönjakelun ja jätevedenpuhdistuksen järjestelmissä, voidaan löytää julkisesta Internetistä. Tarve etähallinnalle ja keskittämiselle, sekä tuotteiden huono suunnittelu ja virheet järjestelmien käyttöönotossa, ovat altistaneet automaatiojärjestelmiä kenen tahansa ulottuville. Yhteiskunnalle tärkeiden kriittisen infrastruktuuriin kuuluvien järjestelmien turvalliseksi saattaminen on tärkeää kansalliselle kyberturvallisuudelle: ongelmat kriittisessä infrastruktuurissa voivat aiheuttaa voimakkaita häiriöitä eri puolilla yhteiskuntaa. Viime vuosina on havaittu kasvava määrä kyberhyökkäyksiä. Sekä rikolliset, että valtiolliset toimijat kehittävät kyberaseita ja myös teollisuusautomaatiojärjestelmiin on kohdistettu hyökkäyksiä. Vuonna 2010 Stuxnet haittaohjelma onnistui tunkeutumaan iranilaisen ydinpolttoaineenrikastamon järjestelmiin ja aiheuttamaan mittavaa fyysistä tuhoa.
Tässä työssä esitellään konsepti, jonka avulla voidaan automaattisesti löytää haavoittuvia teollisuusautomaatiojärjestelmiä, ja raportoida löydökset viranomaisille jatkotoimenpiteitä varten. Työssä esitellään myös prototyyppi, jolla testattiin konseptin toimivuutta oikeilla suomalaisilla järjestelmillä Internetin yli: sormenjälkitietokannan ja porttiskannauksen avulla 2913 IP-osoitteesta löydettiin 91 mahdollista teollisuusautomaatiolaitetta. Epäiltyjä teollisuusautomaatiojärjestelmiä pystytään löytämään Internetistä, mutta löydettyjen järjestelmien kriittisyyden ja tärkeyden arvionti ilman tunkeutumista kohteeseen on vaikeaa. Konseptia tehostaisi huomattavasti automaattinen tietoturva-auditointi, jolla tärkeimmät ja haavoittuvaisimmat kohteet voitaisiin paikallistaa ja poistaa näkyviltä nopeasti. Auditointi ilman järjestelmien omistajien lupaa vaatisi kuitenkin muutoksia lainsäädäntöön.Industrial control systems (ICS), which are used to control critical elements of the society's maintenance such as power generation and electricity distribution, are exposed to the Internet as a result of insecure design, and installation faults. Securing critical industrial systems is important for national cyber-security; malfunctioning elements in the critical infrastructure can quickly cascade into wide range of problems in the society. In the recent years increasing amount of cyber-attacks have been observed, and nations and criminals are developing offensive cyber-capabilities; industrial systems are also targeted as was seen with the Stuxnet-malware in 2010 causing havoc in an Iranian uranium enrichment facility.
In this thesis a concept is presented to automatically find and evaluate exposed ICSs and report vulnerable devices to authorities for remediation. A prototype of the concept is built to prove the viability of the concept and to get data from port scanning real ICS devices in the Internet. With the prototype, 91 ICS devices were found out of the assigned 2913 IP addresses. Traffic volume produced by the scanner was insignificant compared to overall Finnish Internet traffic. The concept, called KATSE, is viable but not without challenges: ICS devices can definitely be identified from the Internet but analyzing the actual importance and purpose of the devices is difficult. Currently the Finnish legislation does not allow system intrusions or unauthorized security auditing even by authorities. Automated security auditing for the found devices would be useful to find the most vulnerable devices first but such auditing would require a change in legislation

Efficient Passive ICS Device Discovery and Identification by MAC Address Correlation
Owing to a growing number of attacks, the assessment of Industrial Control
Systems (ICSs) has gained in importance. An integral part of an assessment is
the creation of a detailed inventory of all connected devices, enabling
vulnerability evaluations. For this purpose, scans of networks are crucial.
Active scanning, which generates irregular traffic, is a method to get an
overview of connected and active devices. Since such additional traffic may
lead to an unexpected behavior of devices, active scanning methods should be
avoided in critical infrastructure networks. In such cases, passive network
monitoring offers an alternative, which is often used in conjunction with
complex deep-packet inspection techniques. There are very few publications on
lightweight passive scanning methodologies for industrial networks. In this
paper, we propose a lightweight passive network monitoring technique using an
efficient Media Access Control (MAC) address-based identification of industrial
devices. Based on an incomplete set of known MAC address to device
associations, the presented method can guess correct device and vendor
information. Proving the feasibility of the method, an implementation is also
introduced and evaluated regarding its efficiency. The feasibility of
predicting a specific device/vendor combination is demonstrated by having
similar devices in the database. In our ICS testbed, we reached a host
discovery rate of 100% at an identification rate of more than 66%,
outperforming the results of existing tools.Comment: http://dx.doi.org/10.14236/ewic/ICS2018.
Management and Security of IoT systems using Microservices
Devices that assist the user with some task or help them to make an informed decision are called smart devices. A network of such devices connected to internet are collectively called as Internet of Things (IoT). The applications of IoT are expanding exponentially and are becoming a part of our day to day lives. The rise of IoT led to new security and management issues. In this project, we propose a solution for some major problems faced by the IoT devices, including the problem of complexity due to heterogeneous platforms and the lack of IoT device monitoring for security and fault tolerance. We aim to solve the above issues in a microservice architecture. We build a data pipeline for IoT devices to send data through a messaging platform Kafka and monitor the devices using the collected data by making real time dashboards and a machine learning model to give better insights of the data. For proof of concept, we test the proposed solution on a heterogeneous cluster, including Raspberry Pi’s and IoT devices from different vendors. We validate our design by presenting some simple experimental results
