NetWalker (also known as Mailto) is the name given to a sophisticated family of Windows ransomware that has targeted corporate computer networks, encrypting the files it finds, and demanding that a cryptocurrency payment is made for the safe recovery of the encrypted data.

HTTP request smuggling is increasingly exploited by hackers in the wild and in bug bounty programs. This post will explain the HTTP request smuggling attack with remediation tips. HTTP request smuggling is an attack technique that abuses how two HTTP devices send requests between each other (typically a front-end proxy or a HTTP-enabled firewall and a backend server) or chaining multiple servers together with different configurations.

Reverse shell is a way that attackers gain access to a victim’s system. In this article, you’ll learn how this attack works and how you can detect it using Falco, a CNCF project, as well as Sysdig Secure. Sometimes, an application vulnerability can be exploited in a way that allows an attacker to establish a reverse shell connection, which grants them interactive access to the system.

Once an attacker has established access and pivoted around to the point of gathering the necessary data, they will work on exfiltration of that data. Not all malware will reach this stage. Ransomware, for example, usually has no interest in exfiltrating data. As with the Collection tactic, there’s little guidance on how to mitigate an attacker exfiltrating data from the enterprise.

It’s a weird time to be alive. Millions of people globally are living under government lockdowns, as we collectively endure the COVID-19 pandemic. COVID-19 has brought to light some fundamental truths about humanity, including our deep-seated need for social interactions. It has also highlighted how reliant we are on critical infrastructure like our healthcare systems and internet connections, both of which are currently strained.
