Everything you should know about the CurveBall Bug

2020 has brought some fantastic as well as drastic things with it and one of these drastic things is the “CurveBall” bug. This came as a shocking threat in the security world and was submitted by the National Security Administration (NSA) to Microsoft. It came in with a fix for CVE-2020-0601 introduced in Microsoft’s first patch. Although initially, this bug was not easy to figure out, later on, it came with a bang. It weakens the entire idea of assurance that we trust to secure web sites and authenticate files.

The liability of this bug depends on ECC (Elliptic Curve Cryptography). It is one of the known methods for digitally signing certificates. This method uses values that help in the production of public as well as private keys. These keys are then used for the exchange of information in a trusted way. ECC gives us an option to validate these files and if it is used in a negative way, then these signs can be faked as well. The scammers make these signs look original to the users.

What is the CurveBall bug?

If an attacker gets his hand on the correct values that were used during the creation of the certificate signs and the corresponding curve, then he may create similar keys. These keys are only checked by the vulnerable functions, and hence malicious or invalid parameters are not taken into consideration while the creation of these keys.
