Techie Tonic: Two CISOs warn Axios breach changes supply chain trust model

In the wake of a critical supply chain attack targeting the widely used Axios JavaScript library, like leading analyst from NST Cyber pointed out, Many CXOs community chief information security officers (CISOs) are urging organizations worldwide to rethink how they trust open-source software.

Axios JavaScript library presents significant opportunities for developers and organizations by streamlining how applications communicate with APIs across both browser and server environments. Its promise-based architecture enables cleaner, more maintainable asynchronous code using modern async/await patterns, while its isomorphic design allows teams to reuse the same logic across front-end and back-end systems, reducing duplication and complexity.

Features like interceptors create powerful hooks for implementing cross-cutting concerns such as authentication, monitoring, and error handling at scale. Automatic JSON transformation simplifies data exchange, saving development time and reducing bugs, and built-in request cancellation improves performance and user experience in dynamic applications. Combined with strong cross-browser compatibility, Axios lowers the barrier to building reliable, scalable, and consistent networked applications across diverse environments.

Speaking in a joint interview with, Hussain Al Khalsan - CISO, Zand Bank and Patrick Pitchappa – CISO, Equiti Group, described the March 30 breach as “one of the most sophisticated npm ecosystem compromises to date.”

“This wasn’t just a malicious package slipping through,” Hussain said. “This was a targeted takeover of trust.”

The attack began when an adversary gained access to the npm account of Axios’s lead maintainer. Within minutes, two compromised versions of the library were published silently embedding a malicious dependency designed to deploy a cross-platform remote access trojan (RAT).

“What’s particularly alarming,” Patrick explained, “is that the attacker didn’t exploit a code vulnerability. They exploited the human and operational layer, the maintainer account and then bypassed all the safeguards we typically rely on.” 

The widely used Axios library became the perfect target due to its presence across web apps, backend systems, and CI/CD pipelines.

The attack introduced a seemingly legitimate package designed to run a hidden post-install script. Once executed, it deployed malware that could profile systems, communicate with remote servers, and run arbitrary code.

“What makes this especially dangerous is that it erases itself,” Hussain noted. “After execution, it deletes traces and replaces them with clean-looking files, making detection extremely difficult.”

Patrick added a stark warning: “If your security depends on checking node modules or running audits after installation, you’re already too late.”

One of the clearest indicators of compromise was the deviation from Axios’s normal publishing process. Legitimate releases are tied to cryptographically verified CI/CD workflows. These malicious versions were published manually using a stolen access token.

“That’s the smoking gun,” Patrick noted. “When a release doesn’t match its expected provenance, no commit, no tag, no pipeline but you have to assume compromise.”

Hussain added that the attacker’s preparation was equally concerning. “The dependency was staged hours in advance to avoid detection by automated scanners. This wasn’t opportunistic but it was deliberate and methodical.”

For enterprises, the consequences extend far beyond a single infected machine.

“This RAT had full remote execution capability,” Hussain warned. “That means credential theft, lateral movement, data exfiltration, looks like everything is on the table.”

Patrick agreed, stressing that any system running the compromised versions must be treated as fully breached. “You cannot trust the integrity of that environment anymore. The only safe path is complete rebuild and credential rotation.”

Both CISOs highlighted the risk to CI/CD pipelines in particular. If a build system installed the malicious package, any secrets injected during that process like API keys, cloud credentials, signing keys, potentially have been exposed.

“CI/CD is the crown jewel,” Patrick said. “If that’s compromised, attackers can poison your entire software supply chain downstream.”

Unlike typical malware, this attack leaves minimal forensic evidence. The presence of the suspicious dependency directory, even if it appears clean but is one of the few reliable indicators.

“You have to look at lockfiles, not just installed packages,” Hussain advised. “That’s where the truth is.”

Network logs also play a critical role. The malware communicates with its command server using a distinctive, outdated browser user agent string, an anomaly that can help identify infected systems.

Still, both experts agree detection is only half the battle.

“Response is where most organizations will struggle,” Patrick said. “Rotating every credential, rebuilding environments, auditing activity and it’s a massive operational burden.”

The incident has reignited debate over the security of open-source ecosystems, particularly those as vast and interconnected as npm.

“We’ve operated on implicit trust for too long,” Hussain said. “This attack proves that trust must be continuously verified.”

Patrick pointed to practical changes organizations should adopt immediately that enforcing strict version pinning, disabling automatic script execution during installs, and implementing stronger controls around dependency provenance.

“But ultimately,” he added, “this is a cultural shift. Security can’t be an afterthought in development workflows.”

While the malicious packages have been removed and the maintainer account is being recovered, the broader impact is still unfolding.

“This isn’t over,” Patrick cautioned. “The real question is how many environments were quietly compromised before detection.”

Hussain echoed the concern: “We’re going to be dealing with the fallout for weeks, maybe months.”

For both CISOs, the takeaway is unmistakable. “This attack didn’t just exploit a software package; it exposed the assumptions we rely on.” And those assumptions need to evolve quickly.
