BlackBerry Cylance has outlined protective measures to safeguard partners and customers from a CylanceProtect bypass disclosed by researchers on July 18.
The solution is three-fold, according to a BlackBerry Cylance blog:
- First, the company has added anti-tampering controls to the parser in order to detect feature manipulation and prevent them from impacting the model score.
- Second, the company strengthened the model itself to detect when certain features become proportionally overweight.
- Lastly, the company has removed the features in the model that were most susceptible to tampering.
