Bypassing MiniUPnP Stack Smashing Protection

By Talos Group This post was authored by Aleksandar Nikolic, Warren Mercer, and Jaeson Schultz. Summary MiniUPnP is commonly used to allow two devices which are behind NAT firewalls to communicate with each other by opening connections in each of the firewalls, commonly known as “hole punching”. Various software implementations of this technique enable various peer-to-peer software applications, such as Tor and cryptocurrency miners and wallets, to operate on the network. In 2015 Talos identified and reported a buffer overflow vulnerability in client […]

Where is my (intermediate) TLS certificate?

By Tobias Mayer When dealing with TLS connections, it is important to understand how a client (in most cases this is a web browser) will be acting. Let’s quickly check some of the steps that are happening when a TLS connection is made. A web server will send its certificate down to the requesting client during the TLS handshake. But it is not only a single certificate but usually a complete chain of certificates. There is the server certificate , in many cases […]

Link Arms Against the Attackers: Observations from the 2016 Cisco ASR

By Martin Nystrom Remember 2007, when the underground economy began to flourish, using simple protocols and static subnet ranges to control their infrastructure? That was the same year Cisco published the first Annual Security Report (ASR) . Nine years later, the drumbeat of cyberthreats grow louder, but the actors and threats are familiar, just as John reminded us when this year’s report was released. What’s Changed? Attackers have vastly increased the sophistication of their infrastructure, incorporated evasive techniques such as encryption and obfuscation, and diversified their revenue streams through ransomware . Defenders are sharing cyber threat intelligence and recognizing […]

Hiding in Plain Sight: Malware’s Use of TLS and Encryption

By Blake Anderson Introduction TLS (Transport Layer Security) is a cryptographic protocol that provides privacy for applications. TLS is usually implemented on top of common protocols such as HTTP for web browsing or SMTP for email. HTTPS is the usage of TLS over HTTP, which is the most popular way of securing communication between a web server and client and is supported by the bulk of major web servers. As TLS has become more popular and easier to use, we have seen the […]
