Ryuk Ransomware has flooded US hospitals, threatening to shut down their operations when they're needed most. Ryuk now accounts for a third of all ransomware attacks in 2020, with its operators finding success while many healthcare organizations are most vulnerable. 

However, the cybersecurity community is coming together to combat this rash of attacks, combining resources to provide network defenders with alerts and intelligence to protect our healthcare institutions. 

To do our part, RiskIQ released the entirety of the infrastructure related to the Ryuk strain of ransomware collected by RiskIQ's Internet Intelligence Graph.

In incident response, speed and visibility are everything, but they can’t be achieved without a 360-degree view of your attack surface. 

RiskIQ PassiveTotal now integrates directly with Microsoft Defender and Azure Sentinel, bringing Microsoft Defender endpoint telemetry and Azure Sentinel alert data directly to the PassiveTotal threat hunting platform. This combination of RiskIQ and Microsoft data enriches threat infrastructure to show pertinent SIEM alerts and endpoint details alongside RiskIQ's rich Internet intelligence to speed up and supercharge investigations. 

RiskIQ and Microsoft joint customers can enable integrations for both Microsoft Defender and Azure Sentinel separately in their organization's account settings in RiskIQ PassiveTotal. Once enabled, analysts can pivot across RiskIQ data during an investigation to understand all the related infrastructure affecting impacted endpoints or existing security tickets. 

Ocean Lotus, or APT32, is a now-notorious threat group active since 2014, best known for its relentless malware attacks and spy campaigns against Southeast Asian governments, dissidents, and journalists worldwide.

While investigating previously reported OceanLotus activity, RiskIQ analysts came across a unique SSL certificate associated with the espionage group's infrastructure. Unique to them, the SSL correlated with more than 70 IP addresses since 2017, a connection that earlier this month helped reporters from German Publications BR24 and Zeit Online track Ocean Lotus activity across Europe.

Further analysis of this custom certificate and its associated IP addresses led us to conclude that it is part of the infrastructure OceanLotus uses to deploy Windows-based malware. Based on RiskIQ's first observation of the SSL certificate in our Internet Intelligence Graph, which links together infrastructure across the entire web, the group has been using this certificate since at least February 27, 2020, and continues to use it today.

Organizations lack visibility into their digital assets, their external network of internet-connected services and devices growing wildly outside their firewalls to support a workforce that will be remote for the foreseeable future. 

The enterprise digital attack surface is now regularly in flux and no longer in the purview of most security controls. More internet devices and services stood up outside the firewall mean complexity goes up, and "non-standard" becomes the norm. Keeping tabs on its composition and the infrastructure of attackers targeting it is one of the most challenging jobs facing security teams today. While organizations grapple with their attack surface, attackers are more active than ever before. More than 375 new threats sprout up every minute, with a wave of phishing attacks, typosquat registrations, and disinformation taking advantage of the COVID-19 pandemic. 

In this new security environment, attack surface management and a 360-degree view of your attack surface. Deep insight across the public internet makes it not only possible but also manageable. 

Ransomware defense is a perpetual cat and mouse game between incident responders and attackers who are continuously evolving their tactics, tools, and strategy. With Ransomware attacks on the rise and costing the US a whopping $7.5 billion in 2019, SOCs and threat hunters must maintain full situational awareness to protect their organization and customers' data—and avoid massive material loss. However, ransomware defense is no easy task and requires a 360-degree view of your organization's attack surface. 

Attackers are more active than ever before, taking advantage of organizations' expanded attack surfaces outside the corporate firewall and across the internet. Phishing attacks, typosquat registrations, and disinformation campaigns aiming to take advantage of COVID-19 and political turmoil are running rampant. Security teams lacking visibility into this new attack surface are coming up dangerously short. 

RiskIQ has been collecting internet data for more than a decade to help organizations meet the challenge of this new generation of threats. The RiskIQ PassiveTotal App puts petabytes of this external Internet security intelligence into Splunk's Data-to-Everything Platform, giving security teams the visibility they need in a platform and workflow they already use. 

The app enables teams to investigate and respond to threats across their organization's attack surface by laying the RiskIQ Internet Intelligence Graph on top of Splunk data—all in one location—to show how internal assets interact with external infrastructure. With this 360-degree view of their attack surface, analysts have unparalleled context and intelligence to detect, investigate, and remediate IoC's and security events.

At the request of our customers, March 9th, RiskIQ's team of trained intelligence analysts began compiling disparate data and intelligence related to COVID-19 into comprehensive reports. Each report combines major updates around COVID-19 and its impacts on cities, neighborhoods, schools, and businesses as well as essential cybercrime data that helps raise the situational awareness of both physical and cybersecurity teams.

Purpose

This intelligence will help inform the decisions of security teams, who face new requirements during these unprecedented times. Here, RiskIQ strives to provide the security community with a single source of factual reporting and informed analysis to help the security community discover unknowns about their environment and investigate threats.

Notice

RiskIQ will be changing the format and frequency of the COVID-19 Daily Update beginning Friday, 05/15/2020. The report will be released every Friday rather than every day. The report will compile the week’s major stories and events and present them in the Notable Events and Digital Exploitation sections. RiskIQ has established a microsite for COVID-19 coverage, located at https://www.riskiq.com/covid19-cybersecurity/. Thank you for your continued readership.
