Cyber Incident Victim: Uniden
Date:
Apr 2019
Location:
United States of America
Summary
A commercial website of a major electronics manufacturer was compromised to host malicious Word documents delivering the Emotet trojan, also identified as Heodo. The attackers stored the malware within a subdirectory and utilized social engineering tactics to prompt victims into enabling macros, triggering the download of malicious payloads including JavaScript files and additional infected documents. Security researchers detected multiple variants of the malware, all flagged by antivirus engines, and alerted the company via automated notifications and direct contact, but the threats remained active for over a day following initial reports. The incident mirrors similar attacks where threat actors exploited organizational web infrastructure to distribute malware like ransomware, highlighting persistent delays in remediation despite external warnings.

Description
Uniden's commercial website dedicated to security products was compromised in early April 2019, with attackers uploading a malicious Microsoft Word document designed to distribute the Emotet trojan, also identified as Heodo or Geodo. The malicious file, discovered by threat tracker JTHL, resided in the '/wp-admin/legale/' directory of the site, which primarily hosted product information for Uniden's commercial security offerings such as IP cameras, analog cameras, and network video recorders. The weaponized document contained a macro that, if enabled, initiated the download of Emotet payloads from the compromised site. URLhaus, a malware tracking platform, confirmed the presence of at least a dozen malicious files hosted on Uniden's domain, including four JavaScript files and multiple Word documents, all matching Heodo signatures. While macros were disabled by default in office software suites, attackers relied on social engineering tactics embedded in the document to instruct victims on enabling macros, thereby triggering the infection chain. VirusTotal detections confirmed all payloads were identified as malicious by antivirus engines at the time of analysis. The exact timeframe of the initial compromise remained unclear, but the malicious content persisted on the site for over 24 hours after initial disclosure.
Security researchers first alerted Uniden to the breach via Twitter on April 10, 2019, and URLhaus automatically generated a notification to the network owner associated with the domain upon adding the malicious URLs to its database. Despite these alerts, the payloads remained active on the site as of the article's publication on April 11, with URLhaus later adding ten additional malicious files on April 12 before correcting an erroneous takedown notice. BleepingComputer contacted Uniden for comment but received no response by the time of reporting. The incident highlighted delays in remediation, paralleling a contemporaneous case involving Northwestern University's Computational Photography Lab subdomain, which hosted Shade ransomware payloads for over a day after notification. Uniden's status as a major electronics manufacturer did not deter attackers from exploiting its web infrastructure for malware distribution, underscoring the broad targeting of organizational websites regardless of size or sector. The compromised site continued serving Emotet variants, posing risks to visitors who might download and execute the malicious documents during the active infection window.
