Pentesting gRPC / Protobuf : Decoding First steps

Posted on by David Vassallo

Protocol Buffers (a.k.a ProtoBuf) and other binary serialization representations are gaining popularity, especially in inter-microservice communication. Unlike JSON or HTTP, ProtoBufs are not human readable (hence the "binary" part of binary serialization) , but that translates into an advantage of  less overhead, leading to performance gains, and the ability to code against a fixed schema … Continue reading Pentesting gRPC / Protobuf : Decoding First steps

What do Smartphone Predictive Text and Cybersecurity have in common?

Posted on by David Vassallo

Maybe the link between your smartphone keyboard and current machine learning research in cybersecurity is not apparent at first glance, but the technology behind both is extremely similar: both leverage deep learning architectures called Recurrent Neural Networks [RNNs], specifically a type of RNN called Long Short Term Memory [LSTM]. One of the main advantages of … Continue reading What do Smartphone Predictive Text and Cybersecurity have in common?
