Cybersecurity researchers have uncovered a never-before-seen dropper that serves as a conduit to launch next-stage malware with the ultimate goal of infecting Windows systems with information stealers and loaders. "This memory-only dropper decrypts and executes a PowerShell-based downloader," Google-owned Mandiant said. "This PowerShell-based downloader is being tracked as PEAKLIGHT." Some of

The proliferation of new top-level domains (TLDs) has exacerbated a well-known security weakness: Many organizations set up their internal Microsoft authentication systems years ago using domain names in TLDs that didn’t exist at the time. Meaning, they are continuously sending their Windows usernames and passwords to domain names they do not control and which are freely available for anyone to register. Here’s a look at one security researcher’s efforts to map and shrink the size of this insidious problem. At issue is a well-known security and privacy threat called “namespace collision,” a situation where domain names intended to be used exclusively on an internal company network end up overlapping with domains that can resolve normally on the open Internet. Windows computers on a private corporate network validate other things on…
