Cloud Security Shift: Attackers Now Favor Vulnerability Exploits Over Stolen Credentials

Published

on

The New Front Door for Cloud Attacks

For years, the story was simple. Attackers wanted your passwords. They phished for credentials, hunted for misconfigured access, and relied on human error to slip into cloud environments. That story has changed dramatically. According to Google Cloud’s latest threat intelligence, the playbook has been rewritten.

The data from the second half of 2025 reveals a startling pivot. Threat actors are now overwhelmingly choosing a different path of least resistance. Instead of trying to steal a key, they’re kicking down the door by exploiting known but unpatched software flaws. This isn’t a minor trend—it’s a fundamental shift in how cloud infrastructure is being targeted.

By the Numbers: A Dramatic Reversal

The statistics tell a clear story of evolution under pressure. In the first half of 2025, exploiting third-party software vulnerabilities was a minor tactic, accounting for just 2.9% of initial access incidents. By the second half of the year, that figure had skyrocketed to 44.5%. It became the dominant attack vector almost overnight.

Conversely, the abuse of weak or missing credentials—long the staple of cloud breaches—plummeted from 47.1% down to 27.2% over the same period. Attackers are rational. They follow the path of greatest reward for the least effort. Right now, that path leads straight through unpatched applications and permissive firewall rules that organizations have left open.

The Poster Child: React2Shell

One vulnerability exemplifies this new era: CVE-2025-55182, known as React2Shell. This critical flaw in React Server Components allows remote code execution. Think of it as a digital skeleton key for servers. Attackers linked to nation-state groups from North Korea and China were among those who weaponized it, but they weren’t alone.

What makes React2Shell particularly telling is the speed of its weaponization. Within a mere 48 hours of its public disclosure in December 2025, multiple criminal groups had already exploited it to install cryptocurrency mining malware on victim systems. It wasn’t a targeted espionage tool for weeks; it was a commodity exploit in days.

The Collapsing Window for Defense

This speed is the core of the new challenge. Google Cloud reports that the window between a vulnerability being disclosed and it being mass-exploited has collapsed “by an order of magnitude.” We’ve moved from having weeks to patch, to having just days. Sometimes, only hours.

If your organization’s patching cycle is measured in weeks or months, you are operating on borrowed time. Your cloud services are functionally vulnerable from the moment a critical flaw is announced until your patch is deployed. Attackers have automated their exploitation pipelines. Defense can no longer be a manual, slow-moving process.

Building a Modern Cloud Defense

So, what’s the answer? The strategy must evolve as quickly as the threat. Relying solely on manual patching is a recipe for failure. Google’s advice is to pivot toward automated, proactive defenses that can act at the speed of the attack.

One key recommendation is to use Web Application Firewalls (WAF) with automated rule updates. These can neutralize exploit attempts at the network edge, buying crucial time to deploy the actual software patch. It’s a stopgap, but a vital one. Centralized visibility tools are also non-negotiable. You can’t defend what you can’t see. Knowing exactly what’s running in your environment, and its patch status, is the first step to closing these digital doors.

Finally, don’t abandon identity controls. While they’re no longer the primary entry point, strong access management remains essential for limiting an attacker’s movement *after* they breach your perimeter. The goal is to build layers of defense that assume a breach will occur and work to contain it. The cloud threat landscape has shifted. Our defenses must do the same.

UK Commits £90m to Cybersecurity and Calls for New ‘Resilience Pledge’

UK Commits £90m to Cybersecurity and Calls for New ‘Resilience Pledge’

The UK government has unveiled a £90m ($120m) injection into UK cybersecurity funding, aimed at bolstering the nation’s defenses against rising digital threats. Announced at the National Cyber Security Centre (NCSC) CYBERUK conference on April 22, Security Minister Dan Jarvis emphasized that the funds would primarily support small and medium-sized enterprises (SMEs). Alongside the financial commitment, Jarvis urged major organizations to sign a new Cyber Resilience Pledge, set to launch this summer.

Why This UK Cybersecurity Funding Matters for SMEs

SMEs often lack the resources to defend against sophisticated cyberattacks. This £90m package aims to help them adopt the Cyber Essentials standard, a government-backed certification that protects against common threats. According to NCSC data, quarterly certifications surpassed 10,000 for the first time last summer. Jonathan Ellison, NCSC Director for National Resilience, noted that uptake grew by 20% in the last financial year—the program’s best performance yet. However, he acknowledged that more work is needed to reach smaller businesses.

This investment is a step in the right direction, but critics argue it’s insufficient. James Neilson, SVP of International at OPSWAT, called the funding “nice on paper” but “nowhere near enough” to address the scale of the problem. He pointed out that many SMEs have no dedicated security teams, making it not just a funding issue but a knowledge gap. Trevor Dearing, director of critical infrastructure at Illumio, echoed this, saying businesses need “practical guidance on how to protect sensitive data and keep critical services running when incidents occur.”

What Is the Cyber Resilience Pledge?

The cyber resilience pledge is a voluntary commitment for large organizations to take three concrete actions: make cybersecurity a board-level responsibility, sign up to the NCSC’s free Early Warning service, and require Cyber Essentials certification across their supply chains. This initiative aims to create a ripple effect, encouraging better practices throughout the ecosystem. However, some experts question whether voluntary pledges will drive real change.

Board-Level Responsibility: A Key Requirement

Making cybersecurity a board-level issue ensures leadership accountability. This aligns with global trends where regulators increasingly hold executives responsible for breaches. By signing the pledge, organizations signal that cyber resilience is a strategic priority, not just an IT concern.

Supply Chain Security Through Cyber Essentials

Requiring Cyber Essentials certification from suppliers helps close vulnerabilities in the supply chain. This is particularly important given that many attacks target smaller vendors to gain access to larger networks. The NCSC’s Early Warning service, meanwhile, provides free threat alerts, helping organizations respond faster to incidents.

Critics Call for Stronger Incentives, Not Just Advice

While the government’s approach is welcomed, industry voices argue it relies too heavily on gentle encouragement. Jonathan Lee, Director of Cyber Strategy at TrendAI, told Infosecurity at CYBERUK: “The government and the NCSC are saying the right things, but we have to move from this position of gently encouraging organizations to providing some incentive.” He suggested exploring tax credits for businesses that invest in resilience, noting that “if we can incentivize people to do that, that would be a good thing.”

Currently, UK businesses developing innovative cybersecurity solutions can claim Research and Development (R&D) tax relief to reduce Corporation Tax or receive cash payments. However, this scheme is limited to tech developers, not the broader SME base that needs support. As James Neilson pointed out, “SMEs either have small security teams or none at all, so it’s not just a funding issue but also a knowledge issue.”

What’s Next for UK Cybersecurity Funding?

The £90m investment and the Resilience Pledge represent a dual strategy: immediate financial aid for SMEs and a long-term cultural shift for larger organizations. Yet, as the debate over incentives continues, the government may need to revisit its approach. For now, businesses should explore Cyber Essentials certification and consider joining the NCSC’s Early Warning service to strengthen their defenses.

In a landscape where cyber threats evolve daily, the UK’s commitment is a positive step—but whether it’s enough remains to be seen. As Jonathan Lee put it, “We’re told it’s a team sport and everyone needs to work together.” The question is whether the government’s playbook will inspire the whole team to act.

Hackers Are Mass-Exploiting the cPanel Bug to Gain Control of Thousands of Websites

A critical flaw in cPanel and WebHost Manager (WHM) is now being actively exploited by hackers, who have already compromised thousands of servers. The cPanel bug exploitation has escalated rapidly, with attackers gaining full control over vulnerable systems and deploying ransomware. This widespread attack underscores the urgency for administrators to patch immediately.

How the cPanel Bug Exploitation Works

The vulnerability, tracked as CVE-2026-41940, allows attackers to bypass authentication and hijack servers via the control panel. According to Shadowserver, a nonprofit that monitors cyber threats, around 550,000 servers remain potentially vulnerable as of Monday. Although the number of compromised instances has dropped from 44,000 to roughly 2,000, this decline may reflect victims taking systems offline or patching.

Security researchers first flagged active attacks on Thursday, noting that hackers were exploiting the bug to take full control of servers. Bleeping Computer reported that Google indexed dozens of websites displaying ransom notes from a group claiming to have encrypted files. Some of those sites have since been restored, but the damage highlights the scale of the cPanel bug exploitation.

Ransomware and Response to the cPanel Vulnerability

The ransom notes included a chat ID for victims to contact the attackers. TechCrunch reached out to the hackers but received no immediate response. Meanwhile, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added CVE-2026-41940 to its Known Exploited Vulnerabilities (KEV) catalog on Thursday, urging federal agencies to patch by Sunday. CISA has not confirmed whether all agencies complied.

Attacks may have begun long before the disclosure. KnownHost CEO Daniel Pearson revealed that his company detected exploitation attempts as early as February 23. This timeline suggests that threat actors were probing for weaknesses weeks before the official advisory. A cPanel spokesperson acknowledged receipt of inquiries but did not provide further comment.

What Administrators Should Do About the cPanel Bug

To mitigate the cPanel bug exploitation, administrators must apply the latest patch immediately. The vulnerability affects all versions prior to the security update. Additionally, consider implementing multi-factor authentication and restricting access to the control panel via IP whitelisting. Monitor server logs for unusual activity, such as unauthorized login attempts or file encryption processes.

For those using cPanel, it is crucial to verify that your hosting provider has applied the fix. If you manage your own server, update through the WHM interface or command line. Ignoring this patch could lead to data loss, ransomware demands, or complete server takeover. For more on securing web servers, check out our guide on web server security best practices.

Broader Implications of the cPanel Vulnerability

This incident highlights the ongoing risk of unpatched software in the hosting ecosystem. The cPanel bug exploitation is part of a larger trend where attackers target widely used management tools. As Shadowserver data shows, the number of vulnerable servers remains high, leaving many sites exposed. Businesses should conduct regular vulnerability assessments and maintain an incident response plan.

Furthermore, the involvement of ransomware groups adds financial pressure on victims. Paying ransoms is not recommended, as it funds criminal activity and does not guarantee data recovery. Instead, focus on backups and disaster recovery strategies. For additional insights, read our article on ransomware prevention strategies.

In conclusion, the cPanel bug exploitation is a critical threat that demands immediate action. By patching promptly and adopting robust security measures, administrators can protect their websites from compromise.
