Microsoft did not address data being leaked from Word documents that are converted to PDFs. Bland and the research paper say that many of the organizations have engaged with the team’s research. The vast majority of the organizations impacted by real-world redaction failures highlighted in the research-including the US Department of Justice, the US courts system, the Office of Inspector General, and Adobe-did not respond to WIRED’s request for comment. “The picture it paints is scary too often redaction is done badly.” It “presents a comprehensive study of redaction tools and the ways in which they can be broken, including exploiting nearly invisible aspects of a document’s typography,” says Lopresti, who was not involved with the research. “I’ve been in lots of discussions with the US court system, I provided them 710 different documents that were just trivial copy-paste style redactions,” says Bland, the paper’s lead author.ĭaniel Lopresti, a professor of computer science at Lehigh University who has studied redaction techniques, says the research is impressive. After examining millions of publicly available documents with blacked-out redactions-including from the US court system, the US Office of the Inspector General, and Freedom of Information Act requests-the researchers found thousands of documents that exposed people’s names and other sensitive details. Plus, a new attack method they devised makes it possible to extract secret details from the redacted text. The findings, from researchers Maxwell Bland, Anushya Iyer, and Kirill Levchenko, say two of the most popular tools for redacting documents offer no protection to the underlying text at all, with the text accessible by copying and pasting it. New research from a team at the University of Illinois looked at the most popular tools for redacting PDF documents and found many of them wanting. When this redaction is done incorrectly, people’s safety and national security can be put at risk. The majority of redactions-by government officials and courts-involve placing black boxes over text in PDFs. Now that most documents are digitized, securely redacting their contents has become harder. If this didn’t work, a chunky black marker pen would do the job. Alternatively, try switching to Agent Workspace, which has an improved, native ticket redaction feature.For years, if you wanted to protect sensitive text in a document, you could grab a pair of scissors or a scalpel and cut out the information. If you choose to redact a URL or text with other special characters, and are experiencing an error, try breaking up the URL into smaller words or components by redacting it in parts around the special character. You see an error when attempting to redact a URL or text with other special characters Agents that need to perform redaction should have this permission. This permission is required because the agent will be deleting data from Zendesk tickets and this data is not recoverable. This error is shown to agents that are in a group that does not have ticket deletion permissions. You do not have permission to perform redaction on this ticket If a user meets only one of the criteria but not both they will not be able to use the Redaction App If you choose to restrict access to the Redaction app using both the Group and the Role definitions you will only allow users that meet both criteria access to Redaction App functions. This section includes some troubleshooting tips and common error messages for the Ticket Redaction app. Redacted attachments are replaced with a blank text file called redacted.txt: Data is permanently deleted from Zendesk servers with no way to recover it. Important: Attachment redaction is permanent and can not be undone.
