On February 25, 2019, researchers from Ruhr University Bochum  and Hackmanit GmbH published pdf-insecurity.org, a detailed explanation of several vulnerabilities they had identified in PDF viewers and online validation services relevant to signature validation in digitally-signed PDF documents. The vulnerabilities are pertinent only to such digitally-signed documents, and not to PDF in general.

Technology in the communications space has evolved and there are now so many more choices now than there were 10 years ago. Platforms have also become more affordable compared to the expensive systems of yesteryears. In addition, the need to mainintain on-premise infrastructure for collaboration tools has reduced or is non-existent in many companies. Workplaces are moving at a rapid pace in the modern day, bringing with it the need for the workforce to adapt to that pace quicker than ever.
