The UK’s National Cyber Security Centre (NCSC) and the US Cybersecurity and Infrastructure Security Agency (CISA) issued an alert on nation-state sponsored exploitation of router infrastructure. The alert calls out SNMP public exposure and one vulnerability in particular - CVE-2017-6742 - which relates to a long known “remote code execution” opportunity on certain Cisco routers. This alert is a timely reminder for all with unpatched equipment to think broadly! We use this opportunity to highlight our data and free daily reports that provide information on the SNMP and Cisco device exposed attack surface (and more!).

We are happy to announce multiple enhancements to our public Dashboard, particularly to the Exploited Vulnerability data collected by our server-side honeypot sensors, thanks to funding provided by the UK Foreign Commonwealth and Development Office (FCDO).

We are happy to announce the first major extension to our newly launched Dashboard - the addition of IoT device statistics and server-side attack statistics, data sets that have been collected as part of the HaDEA EU CEF VARIoT project.

After many years of not having public interface for exploring our extensive cyber threat intelligence data sets, Shadowserver are very excited to make available our new public Dashboard, kindly funded by the UK FCDO. Use our Dashboard to dig into two years of aggregated country level data about many different type of threats, including some unique data sets and vantage points, then visualize the data in various ways that can be easily shared via URLs. Free to use (with attribution) for research, informing policy makers and by journalists/news media in educating the public about cyber security threats.

In May 2018, the US DoJ, FBI and industry partners sinkholed the modular network device infecting malware known as VPNFilter, which Shadowserver has been reporting out for remediation to nCSIRTs and network owners each day since. In February 2022 the UK NCSC, US FBI, CISA and NSA jointly announced the discovery of new network device malware, which they have called Cyclops Blink, and see as a more advanced replacement for VPNFilter. A new Shadowserver Cyclops Blink Special Report was issued to our free daily network report subscribers today, detailing IP addresses believed likely to be infected with the Cyclops Blink malware, and the associated C2 servers.

This blog is the first in a series in which we will take a look at different world regions in order to demonstrate what taking a more holistic view of our data can reveal - starting with the African continent. The derived insight helps us better drive our outreach activities and hopefully allows National CSIRTs in the region, as well as numerous other authorities/partners and private enterprises, to enhance their incident response coordination and share information from our public benefit victim remediation network reports with local communities in a more effective manner.

Private sector partners Microsoft and Bitsight announced their disruption of the Necurs botnet on March 10th 2020. Shadowserver supported the operation, through the use of our Registrar of Last Resort (RoLR) for helping to deal with the millions of potential DGA C2 domains involved, and by making available our victim remediation reporting channels. In this blog post we provide our take on some of the more interesting aspects of this operation, analyze the sinkholed Necurs victim populations and compared their observed demographics with data from the previous decade of spambot takedowns.

The Dridex botnet was sinkholed in October 2015 and the infected victims remediated via Shadowserver's free daily network reports. In December 2019, the US DoJ, FBI and UK NCA unsealed criminal charges against other actors alleged to be behind the Dridex botnet’s activities, via an organization self described as “Evil Corp”. This included a record US $5M FBI Most Wanted cyber criminal reward being offered.

Between May 2016 and April 2019, The Shadowserver Foundation participated in the SISSDEN EU Horizon 2020 project. The main goal of the project was to improve the cybersecurity posture of EU entities and end users through the development of situational awareness and sharing of actionable information. It exceeded KPIs, with 257 sensors in 59 countries, using 974 IP addresses across 119 ASNs and 383 unique /24 (Class C) networks, and collected 31TB of threat data. This blog post provides detail on Shadowserver's role in SISSDEN, including a 3 minute explainer video.

The US DoJ, FBI and international LE partners announce multiple indictments against the alleged operators and customers of the Goznym malware, controlled via the Avalanche platform. Sinkhole data continues to be available from The Shadowserver Foundation, as part of ongoing sinkholing over over 20 Avalanche malware strains.
