Our solution supports sanitization for over 100 common file types, including PDF, Microsoft Office files, HTML and many image file types.Ĭontact us today to understand more about OPSWAT advanced technologies, and learn how to protect your organization comprehensively. Also, file structure integrity is fully reserved, so users can safely use the file without loss of usability.ĭeep CDR ensures every file entering into your organization is not harmful helping you prevent zero-day attacks and evasive malware. As a result, the malicious code is no longer executable. exe did not work with the sanitized file. In this case, Deep CDR removed the unapproved content and reconstructed the DICOM file with only its legitimate data. Let’s examine a sample and see how Deep CDR ( Content Disarm and Reconstruction)can solve the problem: Cylera, a company providing cybersecurity solutions for hospitals, published technical details and proof-of-concept (PoC) code for this vulnerability, which has been assigned the CVE identifier CVE-2019-11687.

exe, attackers can hide malware in an otherwise regular DICOM file. By using a header of another file type, for example. Unfortunately, this preamble design can give threat actors a new way to spread malicious code.

A TIFF viewer can use offset information in the file preamble to access and display the image pixel data in the file while disregarding the rest of the DICOM content.

A DICOM viewer disregards the file preamble, observes the DICM string, processes the DICOM content, and displays the DICOM images.

The preamble is part of a compatibility feature designed to allow medical imagery files to be processed by both DICOM and non-DICOM software. The DICOM file header consists of a 128-byte file preamble, followed by a 4-byte DICOM prefix. A DICOM file comprises a file format definition and a network communications protocol.

Digital Imaging and Communications in Medicine (DICOM) is an international standard for transmitting, storing, retrieving, printing, and displaying medical imaging information, such as X-ray, CT scans, MRIs, and ultrasound.
