Video It is possible to discern someone's SSH password as they type it into a terminal over the network by exploiting an interesting side-channel vulnerability in Intel's networking technology, say infosec gurus. In short, a well-positioned eavesdropper can connect to a server powered by one of Intel's vulnerable chipsets, and potentially observe the timing of packets of data – such as keypresses in an interactive terminal session – sent separately by a victim that is connected to the same server. These timings can leak the specific keys pressed by the victim due to the fact people move their fingers over their keyboards in a particular pattern, with noticeable pauses between each button push that vary by character. These pauses can be analyzed to reveal, in real time, those specific keypresses sent over the network, including passwords and other secrets, we're told. The eavesdropper can pull off this surveillance by repeatedly sending a string of network packets to the server and directly filling one of the processor's memory caches.

Evilnum also relies on various other post-compromise components, including Python-based tools (a reverse shell over SSL script, an SSL proxy, LaZagne, and IronPython), and publicly available tools (PowerShell scripts such as Bypass-UAC and NirSoft utilities, including Mail PassView and ProduKey). "This group targets fintech companies that provide trading and investment platforms for their customers. The targets are very specific and not numerous. This, and the group's use of legitimate tools in its attack chain, have kept its activities largely under the radar. […] We think this and other groups share the same MaaS provider, and the Evilnum group cannot yet be associated with any previous attacks by any other APT group, " ESET concludes.

Familiarize yourself with who we are, what we're working on, and how we run things. " That done. They'd love for you to "join and review our PR (pull request) comments and or even make a PR to close out an open issue, " said Fox. "We've got some easy ones in there. We have labels for tickets that need help, and sometimes just a quick review is all that's needed. We've got presentations and proposals and suggestions, and even security assessments that can all be excellent ways to contribute and grow the community. It just starts by submitting an issue. " In particular, the pair spoke about security assessments of existing projects. After all, it's hard to build security tools until you know what's what in the programs you're already running. Lum said. "one of our core activities is security assessments. "Security assessments are something we do regularly and to date, we have completed five security assessments for CNCF projects. " These include SPIFFE, Spire, in-toto, and OPA (Open Policy Agent).
