TL; DR; If your source code is written in Go and it uses one-way or mutual TLS authentication, you are vulnerable to CPU denial of service (DoS) attacks.

Vulnerabilities This is as ugly as it gets:Â MiSafes kids’ watches allow accessing very specific information on a child, such as photo, gender, age, height, location, and even provide a remote microphone access. API calls are not secured by TLS and are open to Insecure Direct Object Reference (IDOR), meaning that as long as you have […]
Vulnerabilities An API vulnerability was found in the license generation API of Valve’s Steam gaming service and marketplace. Anyone who had registered at their partner portal for developers could call their /partnercdkeys/assignkeys/ with unexpected parameter values (for example, a random string as a partner name and 0 as the request count) and get thousands of keys in the […]
Vulnerabilities Do not use TLS client authentication, unless you are already on TLS 1.3. With TLS 1.2 and earlier, when you use client authentication, the client certificate is transmitted in the clear. This contains enough information to uniquely identify the user. Hundreds of thousands of projects use cURL and purposefully disable the verification of TLS host […]
Vulnerabilities Remini, a mobile app that schools use to communicate with parents, had kids’ profiles including pictures, email addresses, phone numbers, and milestones accidentally publicly exposed through an API.

Vulnerabilities The Shopify vulnerability happened (and was fixed) back in May 2018. This week, Arif Khan goes into the details of the vulnerability and the lessons that we can learn from it for microservices and API security in general. In a nutshell, microservices themselves and the underlying cloud platform expand the attack surface. It is […]
Vulnerabilities GoDaddy 2-step authentication API found to be vulnerable. The API lacks rate limiting and does not impose timeouts after failed second factor attempts. This opens doors for brute force attacks on the second factor. AWS Honeytokens designed by Amazon to help security specialist attract attackers and detect attacks turned out to actually be discoverable. […]
API Vulnerabilities Samsung smart TV security flaw: the equipment would basically accept commands from any source, so someone knowing the device ID would be able to invoke various functions remotely.
