By definition, a novel zero-day attack cannot be prevented. Your organization’s ability to withstand a zero-day attack is completely dependent upon your capacity to detect and respond to an incident post-exploitation. eSentire Managed Detection and Response (MDR) prevents the most advanced cyberattacks from ever breaking through with the detection and response capabilities needed to stop zero-day exploits in their tracks, by providing complete visibility across your IT environment, including endpoints, networks and cloud environments.

A zero-day attack takes advantage of an unknown exploit in the wild that exposes a vulnerability in software or hardware that can be capitalized on by cybercriminals to gain access into your environment and deploy ransomware. These vulnerabilities, also known as zero-day vulnerabilities, are weaknesses in any software used by your organization that have been discovered by cybercriminals, but not yet known to the software vendor. As a result, there are no existing patches that users can apply to repair the vulnerability.
An exploit is a piece of software, data, or a sequence of commands used to take advantage of a vulnerability. This combination of information and ability is used by threat actors to launch attacks with devastating impact to their victims.
Zero-day vulnerabilities are challenging for organizations of all sizes to defend against. They can last for weeks or months before they are detected and investigated, which can finally alert the software vendor to develop a patch.
As soon as a new zero-day vulnerability is discovered, we can help your team proactively identify if your organization is at risk through our eSentire Managed Vulnerability Service. In addition, we also provide ongoing 24/7 Threat Hunting, proactive Indicator of Compromise sweeps, and complete response with eSentire Managed Detection and Response (MDR) to put your business ahead of disruption.

KEY CHALLENGE | Identify the presence of zero-day vulnerabilities before they’re exploited. |
Protect your business from cybercriminals using zero-day exploits to bypass traditional security controls. |
HOW WE HELP | We identify vulnerabilities across traditional and dynamic IT assets so you have continuous visibility into your expanding business environment. We focus on vulnerabilities that present the greatest potential risk to you. You benefit from expert guidance to ensure you’re prioritizing the remediation of these dangerous exploits. |
eSentire MDR combines cutting-edge Extended Detection and Response (XDR) technology, multi-signal threat intelligence and the industry’s only 24/7 Elite Threat Hunters to detect and contain zero-day attacks on your behalf. We minimize the attacker dwell time with a Mean Time to Contain of 15 minutes. Once a threat has been isolated and remediated, we work with you to return affected environments to service. |

Unique to the industry, eSentire MDR includes 24/7 support from an elite team of threat hunters, eSentire’s Threat Response Unit (TRU). TRU proactively researches emerging threats, including zero-days, and operationalizes proactive global threat hunts across our entire customer base as part of our core MDR offering.
Our TRU team has discovered some of the most dangerous threats and nation state cyberattacks in our space.
TRU proactively hunts and builds new detection models leveraging the power of artificial intelligence pattern recognition to drive new intelligence, containment and response actions across our Atlas XDR platform.
Watch this video with one of eSentire’s Elite Threat Hunters, Spence Hutchinson, as he reviews the Kaseya VSA supply chain attacks. Spence outlines how eSentire’s Security Operations Center (SOC) & TRU were able to quickly respond on our customer’s behalf and notify Kaseya of the breaches.
In these 2018 and 2021 attacks, threat actors leveraged zero-day vulnerabilities to push Cryptomining malware and Ransomware to Kaseya VSA customers. Our BlueSteel Machine Learning Engine identified malicious Powershell commands being executed. eSentire’s actions to detect, respond and remediate these attacks demonstrate the importance of MDR services that go beyond alerting and host isolation to deliver complete & robust response.
Whether or not a newly discovered vulnerability will lead to widespread exploitation is dependent on who discovered it. Zero-day vulnerabilities are most commonly discovered by:
Cybersecurity researchers, who strive to discover vulnerabilities so they can be patched before they can be exploited by adversaries. These researchers may be a part of the software vendors’ in-house team or cybersecurity practitioners who work in-house at organizations.
White hat researchers, who first notify the software vendors of vulnerabilities so they can be patched before publishing the research at a later date.
Nation-state researchers, whose goal is to discover vulnerabilities that pose a risk to national security, in which case they may notify the relevant software vendors. However, nation-state researchers may also choose not to notify the software vendor if the goal is to exploit the vulnerability for national interest.
Black hat researchers, whose primary aim is to develop exploits that can be used for malicious purposes.
Once the zero-day vulnerability is discovered, a threat actor must know how to exploit it. Some vulnerabilities are easily exploitable, requiring only slight modifications to existing attack tools, while others are much more complex. With this latter group, there is often a series of incremental steps:
Vulnerability is discovered
Proof-of-concept (PoC) demonstrates the viability of exploitation
Exploit is weaponized in a practical technique
Exploit weaponization and tooling is optimized
Depending on how difficult it can be to weaponize the exploit, this process can take a few days to months. Once weaponized, an exploit may be used exclusively by a particular threat actor or sold on Dark Web marketplaces.
In August 2021, a cybersecurity researcher revealed three ProxyShell zero-day vulnerabilities and how they could be exploited on Microsoft Exchange servers at Black Hat 2021. Quickly after disclosure of the technical vulnerability details, cybercriminals began to determine how they could exploit the ProxyShell vulnerabilities.
eSentire’s Threat Response Unit (TRU) was able to coordinate with our 24/7 Security Operations Center (SOC) Cyber Analysts to proactively identify if any customers were impacted by the vulnerabilities, develop detections based on the Indicators of Compromise (IOCs), and perform global threat hunts for ProxyShell.
In December 2021, security researchers released details and Proof-of-Concept (PoC) exploit code for Remote Code Execution of a vulnerability impacting the Apache Log4j Java-based logging library.
Shortly after, eSentire’s Threat Response Unit (TRU) observed scanning for the vulnerability, Cobalt Strike activity and crypto mining payloads in addition to the targeting of web servers. There were also reports in the wild of the Log4j exploitation resulting in ransomware deployments.
In response, TRU coordinated with our 24/7 SOC Cyber Analysts to proactively identify if any customers were impacted by the vulnerabilities, developed detections based on the Indicators of Compromise (IOCs), and conducted proactive global threat hunts for Log4j.
