Threat Emulation Engine Update - What's New?
Solution

This solution contains the new items and fixes for each Threat Emulation Engine Update. It will be updated each time a new Engine Update is released.

To check the current version of Threat Emulation Engine Update, run either one of these commands:

  • [Expert@HostName]# tecli advanced engine version

  • [Expert@HostName]# cat $FWDIR/teCurrentPack/te_ver.ini

To check the current version of Threat Emulation Image, run the following command:

  • [Expert@HostName]# tecli show downloads images

For the latest Threat Emulation malware detection rules, refer to sk117672 - How to update the Threat Emulation malware detection rules.

For file types supported in Threat Emulation, refer to sk106123.

Date Release Version What's New
04-Apr-2018 6.15

Engine:

56.990002329

IMAGE_READY = 234

 • Added support for .bat and .cmd files that arrive in mail attachments.

These file types are not available in the Threat Emulation Supported File Types menu.

• Detection improvements and FP reduction

Introduced advanced human simulation – Threat Intelligence group has observed many files in the wild that were using a new evasion technique (implementation in images rev. 234)

• CADET for executable files only – silent mode o

Cadet aims to improve Threat Emulation precision on executable files by transferring all of existing TE features (such as emulation results, reputation, and others) to a AI model tuned to improve accuracy – increase detection and reduce false positive. Cadet is focused preliminary on executable files, and will apply only for cloud emulations at this first stage.

Cadet is currently being deployed in Silent mode – meaning it does not change the verdict on TE.

• FP handling improvement 

Smarter management of global TE Cloud Cache, to increase cached verdict reliability and prevent FP pollution.
