Using Global Honeypot Networks to Detect Targeted ICS Attacks

Defending industrial control systems (ICS) in the cyber domain is both helped and hindered by bespoke systems integrating heterogeneous devices for unique purposes. Because of this fragmentation, observed attacks against ICS have been targeted and skilled, making them difficult to identify prior to initiation. Furthermore, organisations may be hesitant to share business-sensitive details of an intrusion that would otherwise assist the security community. In this work, we present the largest study of high-interaction ICS honeypots to date and demonstrate that a network of internet-connected honeypots can be used to identify and profile targeted ICS attacks. Our study relies on a network of 120 high-interaction honeypots in 22 countries that mimic programmable logic controllers and remote terminal units. We provide a detailed analysis of 80,000 interactions over 13 months, of which only nine made malicious use of an industrial protocol. Malicious interactions included denial of service and replay attacks that manipulated logic, leveraged protocol implementation gaps and exploited buffer overflows. While the yield was small, the impact was high, as these were skilled, targeted exploits previously unknown to the ICS community. By comparison with other ICS honeypot studies, we demonstrate that high-quality deception over long periods is necessary for such a honeypot network to be effective. As part of this argument, we discuss the accidental and intentional reasons why an internet-connected honeypot might be targeted. We also provide recommendations for effective, strategic use of such networks.Gates Cambridge Trus

Disseminated seronegative echinococcosis: difficulties of diagnosis and treatment

Disseminated seronegative echinococcosis, occurring with damage to soft tissues, bones and joints, is a rare variant of the course of helminthiasis, often associated with diagnostic difficulties, a high probability of complications and difficult treatment.&#x0D; This article presents a case of disseminated seronegative echinococcosis, clinically and laboratory simulating a severe form of WeberChristian panniculitis complicated by sepsis. The advantages and disadvantages of serological and morphological studies in the verification of disseminated echinococcosis are discussed, as well as the feasibility of using repeated histological studies in cases of echinococcosis under the masks of rheumatic diseases.</jats:p
