MetaDefender Anti-Malware Engine Name Updates: What You Need to Know

Multiscanning by anti-malware engines is a critical component of OPSWAT’s advanced cyber security solutions. To be consistent with the latest vendor terminology, we will make modifications to the names of the anti-malware engines in MetaDefender. This change will be effective starting December 1, 2021.

The adjustment applies to MetaDefender Cloud, and any Windows or Linux version of the MetaDefender suite: MetaDefender Core, MetaDefender ICAP Server, MetaDefender Email Gateway Security, MetaDefender Core AMI, MetaDefender for Secure Storage, and MetaDefender Kiosk.

The name updates will affect these areas:

• Module page
• Scan results page
• REST API results
• Log content

The engine ID data expressed in JSON will remain the same. For example:

Old:

"Zillya": {

 "def_time": "2021-07-01T04:02:53.000Z",

 "eng_id": "zillya_1_windows",

 "location": "local",

 "scan_result_i": 0,

 "scan_time": 81,

 "threat_found": "",

 "wait_time": 6

}

New:

"Zillya!": {

 "def_time": "2021-07-01T04:02:53.000Z",

 "eng_id": "zillya_1_windows",

 "location": "local",

 "scan_result_i": 0,

 "scan_time": 81,

 "threat_found": "",

 "wait_time": 6

}

Action to Take

If you don’t have any custom integrations in your MetaDefender implementation, no action is needed.

If you already have custom integrations (for example, you have scraped logs for the engine names or called the REST API of MetaDefender Core and hard-coded the engine names), follow these steps:

1. Prepare to change the hard-coded strings
2. Pin the engines 1 to 2 days in advance
   Note: Pinning engines will avoid them being overwritten when you allow automatic product updates.
3. After December 1, 2021, change your hard-coded strings and unpin the engines
4. Check to make sure everything works as expected
