The detection of new malware samples indicates the level at which cyber threats are evolving. In the last 24 hours, security researchers have released details about two new malware that are being used in the wild. One of them is a new variant of the BazarLoader dropper that comes with two new malware delivery techniques. The second is a new Tardigrade malware loader that bears resemblance to Smoke Loader. While the former has affected users in the U.S., the latter is being actively used against biotech companies, with the latest attack being detected in October.

And just like that, the list of stealthy malware loaders continues to expand with the discovery of another new malware dubbed RATDispenser. It gets its name from the type of payloads (RATs) it distributes.
