Through our managed detection and response (MDR) monitoring, we discovered the modular Emotet malware distributing the Nymaim malware, which then loads the Nozelesn ransomware. We detected this particular Emotet variant in one of our monitored endpoints in the hospitality industry in February 2019. For this threat investigation, we also sourced 580 similar Emotet file attachment samples from our telemetry and gathered data between January 9, 2019 and February 7, 2019.Read More
We discovered a phishing campaign targeting South Korean websites and users’ credentials using the watering hole technique. Labeling the campaign Soula, cybercriminals injected a malicious JS code in at least four websites for a fake login pop-up to appear at intervals before they can continue using the pages.Read More
Security researcher Michael Stepankin reported a vulnerability found in the popular, open-source enterprise search platform Apache Solr: CVE-2019-0192. It’s a critical vulnerability related to deserialization of untrusted data. To have a better understanding of how the vulnerability works, we replicated how it could be exploited in a potential attack by using a publicly available proof of concept (PoC).
Successfully exploiting this security flaw can let hackers execute arbitrary code in the context of the server application. For example, an unauthenticated hacker can exploit CVE-2019-0192 by sending a specially crafted Hypertext Transfer Protocol (HTTP) request to the Config API, which allows Apache Solr’s users to set up various elements of Apache Solr (via solrconfig.xml). Affected versions include Apache Solr 5.0.0 to 5.5.5 and 6.0.0 to 6.6.5.Read More
Telecommunications or telecom technology is the underpinning of the modern internet, and consequently, the internet’s growing segment, the internet of things (IoT). At its best, this relationship is exemplified as advances in network connectivity as we move to 5G. In our paper with Europol’s European Cybercrime Centre (EC3), “Cyber-Telecom Crime Report 2019,” we explore how this relationship can also be used to threaten and defraud the IoT.Read More
A critical remote code execution (RCE) vulnerability (CVE-2019-7238) was found in Sonatype’s Nexus Repository Manager (NXRM) 3, an open source project that allows developers, such as DevOps professionals, to manage software components required for software development, application deployment, and automated hardware provisioning.Read More
