Overview  

On November 26, 2025, D-Link was made aware of Fortinet's  FortiGuard Labs' disclousre on malware named “ShadowV2” spreading via IoT vulnerabilities. 

The Disclosure accuses legacy EOL/EOS  D-Link products, that have public posted notice retire and replace approaching 10 years. The resources associated with these products have ceased their development and are no longer supported.

D-Link Systems, Inc. recommends retiring these products and replacing them with products that receive firmware updates.

This announcement covers all models disclosed as well as some additonal storage products the we recommend the owners/user to retire their use.

This exploit affects legacy D-Link products and all hardware revisions that have reached their end-of-life ("EOL")/end-of-service-life ("EOS") Life Cycle. Products that have reached their EOL/EOS no longer receive device software updates and security patches and are no longer supported by D-Link.
 

D-Link US recommends retiring and replacing D-Link devices that have reached EOL/EOS. Please get in touch with your regional office for recommendations (LINK). 

Regardless of product type or sales channel, D-Link's general policy is that when products reach EOS/EOL, they can no longer be supported, and all firmware development ceases for them. Please read the information and recommendations below.

Recommendation for End-of-Support/End-of-Life Products

   
From time to time, D-Link decides that some of its products have reached the End of Support ("EOS") or End of Life (“EOL”). D-Link may choose to use EOS/EOL as a product due to technological evolution, market demands, innovations, and efficiencies based on the latest technologies, or the product may mature over time. In either case, it should be replaced by functionally superior technology.

For US Consumer

If a product has reached the End of Support ("EOS") or End of Life ("EOL"), it typically does not receive further extended support or development.

Typically, D-Link cannot resolve device or firmware issues for these products since all development and customer support have ceased. 

D-Link US is prohibited; from providing support for these EOL/EOS products, if you are outside the US, please contact your regional D-Link office. If your device was provided by a licensed carrier (service provider) and firmware, please contact your carrier (service provider). Many devices on this list have available 3rd party firmware; D-Link does not support open firmware, which voids any warranty and is solely the responsibility of the device's owner.

D-Link strongly recommends retiring this product and cautions that further use may be risky to connected devices. If US consumers continue to use these devices against D-Link's recommendation, please ensure the device has the latest firmware, which can be located on the Legacy Website links above. Please also ensure you frequently update the device's unique password to access its web configuration and always have WIFI encryption enabled with a unique password.
