Axios NPM Supply Chain Compromise: Malicious Packages Deliver Remote Access Trojan - PDF-XChange Unaffected

Security Bulletin Apr 3,  2026

On March 31, 2026, attackers compromised the official Axios package on the Node Package Manager (npm) registry. Axios is one of the most widely used open-source libraries for making web requests, with over 100 million downloads per week. It is embedded in web applications, mobile apps, backend services, and automated build pipelines across virtually every industry.

PDF-XChange uses Axios libraries on our website. However, we at PDF-XChange, had not as yet completed our review and testing of the latest release and therefore had yet to approve or implement the release that was compromised. 

We have thoroughly reviewed our own servers and no malware was detected as expected and consequently we are pleased to confirm that our systems are unaffected in any way.

Best regards,

Web site Service updates - Monday 9th March 2026

Web site Services updates - Monday 9th March 2026.
Over the past months we have experienced a huge increase in attempts by malicious 3rd party actors to disrupt service for our primary domains and web site. In particular at specific times each week we have noticed automated attempts to break down our defences and it has been necessary this weekend to take action to ensure that both ours and our clients services and data are always adequately protected.

This is a regrettable but not surprising consequence of the staggering increase in our sales over the past 2 years - up over 100% for our most popular products - as many of our competitors have ceased to provide their products on anything but the 'subscription model - forcing clients to pay greatly increased (and far more lucrative for them) monthly or quarterly fees,  should they wish continue to use their software products and applications. It is our firm intention to continue to offer our products on a perpetual license, with no mandatory monthly, quarterly or annual fees.

During the course of today as these services are updated and propagated you may notice a temporary deterioration in response times to web site requests and  delivery - we sincerely apologise and will do our utmost to keep any interruptions to our services to the absolute minimum.

Thank you for your understanding and patience as we act to improve our security and defences against these criminal and nefariously motivated groups.

Software Developers - SDK Website Maintenance

We would like to give our software development clients using our software development kits (SDKs) advance warning that the SDK section of our website (sdkhelp.pdf-xchange.com) will experience a brief downtime period for maintenance on Wednesday, December 17th from approximately 9:00–10:00 AM PST. Visitors to the site may encounter interruptions and/or delays within that time period. Note that all other areas of the website, such as orders, account/licensing/information management etc, will not be affected. 
Thank you for your patience while we carry out this routine but necessary maintenance.

Mail Delays Due to the Canada Post Strike September 2025

All PDF-XChange clients should note that since September 26, 2025 the national membership of the Canadian Union of Postal Workers (CUPW) has been on strike. The strike has resulted in the delay of millions of letters and packages being delivered across Canada. If any clients have sent payment via cheque during this period then it will probably not be delivered for some time, and there will be a significant backlog even when the strike is resolved. If you're experiencing any such delays then please contact sales@pdf-xchange.com for assistance. There are alternative options for sending cheques, such as using a courier, and different payment methods - credit card, Paypal, and wire transfer options - are available.

Kind regards, 

The PDF-XChange team
