We covered three methods in particular: automated image creation and deployment, immutable image deployment and containers. We’ll now explore how organizations can make the best of these methods in a dynamic environment. Dealing with...

Digital criminals have launched a new attack campaign that they're using to target U.S. petroleum companies with the Adwind RAT. Netskope discovered the operation in the beginning of September and found that it was distributing the Adwind RAT from “members[.]westnet[.]com[.]au/~joeven/.” With this URL in mind, it's likely that the individual...

As a regular reader of Tripwire, you are aware that October is National Cyber Security Awareness Month. Way back in 2015, when the world was an entirely different place, I contributed an article that offered some tips for protecting yourself. Those tips are still relevant: Password management.

Every year when I go to Black Hat USA and DEFCON, I am reminded of the constant battle between light and dark…wait…that’s Return of the Jedi…. I mean of the constant battle between infosec and the big bad hacker. And it’s not just the uber sophisticated hacks that involve fuzzing and SQL Injections (Am I showing my age there?) or any of the other...

Samples of a new malware family called "Divergent" are using both NodeJS and WinDivert in a series of fileless attack campaigns. Cisco Talos didn't identify the exact delivery method for Divergent. Even so, its researchers observed that the samples they analyzed staged and stored configuration date on the registry like other fileless malware. They...

Just a few years ago, most IT environments were made up of deployed servers on which personnel installed applications, oftentimes as many as that one system could handle. They then remained and ran that way for years. In the meantime, the IT team maintained the system and updated the applications as needed. Sometimes there were test versions of...
