Cyber threat intelligence: What threat trends tell us
July 15, 2021
We all know that disruption is the threat actor’s playground—and there’s plenty of it around at the moment. Threat actors are connecting the dots to improve their tactics and collaborate with each other to take advantage of an evolved ecosystem. Not only have we seen increased pressure from threats related to remote working vulnerabilities, but also cybercrime actors have profited from the crucial roles played by local government, healthcare and supply chain providers. In particular, they’ve stepped up and stepped in to challenge critical infrastructure business operations continuity.
In our 2021 Cyber Threat Intelligence Report Accenture draws out the often unseen connection between the new ecosystem, the Dark Web economy, ransomware disruptions, commodity malware and pirated software abuse and their collective, disruptive effects on both information technology (IT) and operational technology (OT) environments.
Public policy responses are now positioning businesses, especially in OT and other critical infrastructure sectors, to reach for long-needed security improvements. The idea is to convert the new ecosystem into an opportunity for improving security, exploiting its potential more than ever before—in short, providing an environment in which organizations can recover better.
Recovering better will take sustained effort in a high-risk environment. In our monitoring and threat analysis operations, the Accenture Cyber Threat Intelligence team (Accenture CTI) has examined recent threat trends and offers expert perspectives on what to do about them. And we monitor this landscape on an ongoing basis.
Here’s a snapshot of what we’ve seen:
Threat actors buy malware logs and extraction tools easily on the Dark Web. From these, they pull out network credentials. Stolen credentials offer a gateway vector for often-debilitating network intrusions and operations, letting threat actors avoid anti-phishing defenses. For example, actors who launched a critical infrastructure ransomware attack in May 2021 did so using compromised VPN credentials.
There is also a great deal of churn in the alliances among cybercriminal threat actors’ social networks, making attribution difficult. Groups are rebranding or swapping code amongst themselves to hide their identities within criminal communities.
After gaining access to a victim’s network, threat actors need to deploy malware that spreads easily in the network to pull out the data they intend to ransom. Commodity malware including Qakbot, IcedID, DoppelDridex, Hancitor fits the bill, alongside pirated versions of Cobalt Strike.
The global ransomware crisis has entered a new phase, as threat actors adopt stronger pressure tactics and tackle targets such as manufacturing and critical infrastructure. Ransomware actors can choose from four pressure techniques: local denial of access (encryption); leak extortion (also known as “name and shame” tactics); distributed denial-of-service (DDoS); and contact with a victim’s customers. Responding to multiple techniques at once can be challenging and stressful, especially if a victim organization has not already invested in prevention, preparation and pre-deployment defenses.
To pay or not to pay ransoms is still a big question in many people’s minds. Accenture has reinforced United States federal government guidance: Don’t pay ransoms. Companies could be subject to financial penalties if they inadvertently pay a sanctioned entity and cannot guarantee the return or deletion of stolen data.
Instead, organizations should focus on prevention and recoverability: protect against commodity malware; stay alert for Dark Web sales of stolen credentials; segment systems to minimize the lateral movement of ransomware; deploy good logging systems to detect anomalous network behavior; and create backups and playbooks to strengthen operational resilience.
When a breach does occur, Accenture recommends reacting quickly, working with legal counsel and applying incident response and communications best practices. With all these trends happening together, it can be a particularly worrying time for OT and critical infrastructure providers. Three possible things to remember are:
For OT and critical infrastructure and key resources providers in the United States, the Executive Order on Improving the Nation’s Cybersecurity issued in May 2021 goes a long way towards addressing these threats and trends.
Providers are now on a path to improve software design, secure supply chains, invest in more easily secured digital technologies, improve cybersecurity focus and work more transparently with government counterparts to drive a more stable business environment. It will help all security teams everywhere to connect their own dots and protect their business operations from cyber threat evolution.
