News & Insights

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.

The huge Mirai Botnet #14 IoT botnet attacks were successfully stopped and sinkholed by the German BKA and The Shadowserver Foundation, and the actor behind them was identified, arrested and prosecuted in both Germany (with the BKA) and the UK (with the NCA). Sentencing details were made public in the UK today.

Breaking news: Shadowserver's malware repository now exceeds the One Billion Binaries milestone (and, spoiler alert - not everyone in the team is as excited by this news as some of us). We provide a little bit of history about the growth of our malware collection, and the some of the challenges we continue to face.

Year 3 of our ongoing Avalanche operations with international law enforcement continue to provide protection for over 2 million unique IP addresses per day against 20+ different strains of malware, including the Andromeda dropper from year two. This has required an unprecedented blocking/seizing of over 2.4 million malicious domain names to date. Sinkhole data continues to be available to subscribers via our free daily network reports.

Operation Eversion was the takedown of the highly sophisticated Boaxxe/Kovter botnet based "3ve" (pronounced "Eve") ad fraud network by the DoJ/FBI, Google, WhiteOps and other industry partners. Sinkhole data is available from Shadowserver.

VPNFilter is a multi-stage modular malware platform designed to infect small office and home office (SOHO) routers and other network devices, believed to be connected to APT28. It was sinkholed under court order by the FBI, with infected device data being made available via Shadowserver's free daily network reports.
