James Berthoty has over ten years of experience across product and security domains. He founded Latio Tech to help companies find the right security tools for their needs without vendor bias. In his role, Jeevan handles a range of tasks, from architecting security solutions to collaborating with Engineering Leadership to address security vulnerabilities at scale and embed security into the fabric of the organization. Currently, risk and severity are two words used interchangeably when they should not.

• However, we believe that POC code likely hastens exploitation attempts for vulnerabilities that do not require user interaction.
• To that end, explicitly declared policies (from both researchers andvendors) are a good thing.
• Indusface’s 2026 research documents that 28.3 percent of exploited vulnerabilities were weaponized within 24 hours of disclosure.
• We start from the official public timeline (bottom) that determines the public or private disclosure of a vulnerability till the time of the release of a patch/bugfix.

What Are Typical Remediation Timeframes For The Highest-risk Vulnerabilities?

For broader application security data, see my Application Security Statisticspage. By taking action to address GNSS vulnerabilities, and implementing resilient timing solutions, organisations will improve the security and reliability of their digital infrastructure. Ontario courts were affected by a cyberattack involving Thomson Reuters’ C-Track case management platform. Learn what happened, what data may be exposed, and what organizations can learn from the breach.

For high-priority vulnerability categories, network edge devices and identity platforms in particular, the sub-24-hour exploitation window is now the norm rather than the exception. CVE volume is growing faster than any enrichment or prioritization system can process. The share of vulnerabilities exploited before or on their disclosure date has reached 32 percent. And the technology categories being hit hardest, network edge devices, identity platforms, and a newly emerging AI infrastructure attack surface, are precisely the categories that traditional patch management programs handle most poorly. Once identified, classify vulnerabilities based on their severity and potential impact — drawing on vulnerability intelligence to understand which issues are actively being exploited and therefore most urgent to address. Rootshell Security offers information on vulnerability assessments and how to carry out a vulnerability assessment to help organizations identify and understand their security weaknesses.

The window between ‘this vulnerability exists’ and ‘this vulnerability is being exploited against real targets’ has compressed to the point where, in the median case, the window is measured in days. In the worst cases, it is measured in hours; or it has already closed before the vulnerability is disclosed. A zero-day vulnerability is one that is being actively exploited while it is still unknown to the public, the vendor, and the defender.

Ranking vulnerabilities also allows you to establish the potential impact vulnerabilities will have on the organization and helps you determine where certain remediations need to fit into your remediation timelines. Typically, timing attacks exploit microsecond-to-millisecond differences in processing, network responses, or algorithm branching. According to top sources that document cryptographic side channels, a timing attack does not directly break cryptography; rather, it exploits observable behaviors that correlate with secret values. In 2025, these attacks often target remote services (e.g., web APIs), local processes, and hardware devices where timing information leaks are accessible. Organizations should evaluate their exposure to timing attacks whenever they develop authentication systems, cryptographic applications, APIs, or services that process sensitive information.

Vulnerability Walkthrough – Timing-based Username Enumeration

Vulnerability management policies outline how your organization manages vulnerabilities within its IT environment. This type of policy states the plans and agreement for how and when vulnerabilities will be addressed and remediated. A patch management policy is an example of a vulnerability management policy, which contains documentation on how patches are managed and applied to endpoints within an organization. Timing attacks, in general, are a class of attacks that exploit the timing behaviour of a system to extract sensitive information. These attacks can exploit various types of timing-related vulnerabilities, such as measuring the time it takes for a system to perform certain operations or exploiting the order that sensitive processes are executed.

MITRE’s CWE Top 25 identifies the weakness categories behind the largest share of real-world CVEs. The 2025 list analyzed 39,080 CVE records for vulnerabilities reported between June 2024 and June 2025. The most effective timing solutions make complex technology accessible without requiring specialist expertise. Plug-and-play implementations that can be deployed in minutes rather than themeetheage.com/sign-up-process months allow organisations to build resilience without extensive technical resources or lengthy implementation projects. When GNSS signals fail or become compromised, entire sectors of the economy can be disrupted. Without proper synchronisation, server clocks begin to drift at rates of up to two seconds per day, creating data inconsistencies, transaction failures, and compliance violations across digital estates.

This process is essential for your business to know how to properly address certain vulnerabilities in your IT environment. Other real world timing attacks have taken place that have allowed attackers to figure out the identity (see Twitter Silhouette Attack). On Facebook, it was possible to create a page that had age restrictions setup such that only a 32 year old could view it, by creating a page for each age, and then requesting each one it was possible for another site to tell how old you are.

For vulnerabilities that have already been exploited, the subsequent introduction of publicly available exploit or POC code indicates malicious actor interest and makes exploitation accessible to a wider range of attackers. There were a number of cases in which certain vulnerabilities were exploited on a large scale within 48 hours of PoC or exploit code availability (Table 2). 73 of the 884 KEV vulnerabilities first exploited in 2025 were used to launch ransomware attacks. This makes initial access detection, not lateral movement detection, the operationally critical control layer.

Building Tomorrow’s Timing Infrastructure

The most common level and objective when fixing vulnerabilities at an early stage. SLA or SLO usually are the target times from the vulnerability being identified and discovered in the system or the ticket being raised with the individual team (resolution SLA). The resolution time and SLAs are fairly different between asset types across the various categories. As seen above, once the first character in the input string matches theAPI key, the string comparison takes twice as long, and the attacker nowknows the first character of the API key.

Manual remediation of IT vulnerabilities can be time-consuming and may prevent you from reaching your remediation timeline goals. IT automation frees up your technicians to perform other tasks and ensures that essential vulnerability management and remediation tasks are completed in a timely manner. An up-to-date IT asset inventory provides you with correct information about your IT environment so you can accurately identify vulnerabilities within the entire infrastructure. With full visibility into the environment, it helps prevent assets from being overlooked and enables quicker identification of vulnerabilities. This helps speed up remediations, so your systems are vulnerable for a shorter period.

In this four-part blog series, FireEye Mandiant Threat Intelligence highlights the value of CTI in enabling vulnerability management, and unveils new research into the latest threats, trends and recommendations. Prioritizing IT vulnerabilities based on their severity and exploitability is essential. Doing so allows you to dedicate and allocate the necessary resources for remediation and plan your remediation timelines accordingly.

Thus,with a 32-byte API key, the string comparison will take 31 times longer to runwhen the strings are equal, than when their first characters are different. Create a policy with clear guidelines on how to handle the identification, assessment, and remediation of vulnerabilities. Assign specific vulnerability management roles to employees or specified end users to ensure the policy is implemented. CVE counts measure disclosure activity, not real-world risk — a year with more CVEs is not automatically a more dangerous year. Fix times are getting longer on average, but the best-performing teams show it doesn’t have to be that way. For how the OWASP Top 10maps to testing in practice, see my vulnerability management lifecycleguide.

Before we move on to the timeline, let’s dive into the definition of SLA in this particular context. If they do not already have this information, a quick surveyof likely subdomains will reveal the login page of BigCorp atbigcorp.sampleapp.com; no sophisticated techniques required yet. Use blinding techniques for cryptographic protocols (exponent blinding) to randomize timings. Do not reveal subtle response differences (HTTP status codes, different error messages) that correlate with secret checks; return uniform errors. For cryptographic algorithms, use implementations vetted for constant-time behavior.

Additionally, the KyberSlash attack targeted post-quantum cryptographic systems by using fabricated ciphertext to measure decryption times, allowing attackers to reverse engineer key pairs. These examples highlight the diverse ways timing attacks can be employed to compromise security. While the majority of the observed vulnerabilities were zero-days, 42 percent of vulnerabilities were exploited after a patch had been released. For these non-zero-day vulnerabilities, there was a very small window (often only hours or a few days) between when the patch was released and the first observed instance of attacker exploitation. Table 1 provides some insight into the race between attackers attempting to exploit vulnerable software and organizations attempting to deploy the patch. The 519-day median patching time in healthcare and 577-day median in education deserve special attention.
