11/10/2023 0 Comments Crypter that works with nanocoreThe broad array of malware that it delivers gives CTU researchers a hint of how it's being used by cybercriminals, according to Pantazopoulos. The core processor then injects and executes the configured main payload and implements its anti-tamper controls. It can also display the fake message box, checks for VMs and sandboxes, implements persistence, and processes add-on packages. The initial loader decodes, loads, and executes the core processor, which then extracts, decrypts, and parses its configuration. NET-base DLL as the core processor – needed to launch the malicious payloads. NET-based executable as the initial loader and a. More research is needed to further confirm any links.ĭarkTortilla includes two components – a. NET connection, an elaborate configuration, the ability to display a custom message box to the victim and anti-virtual machine and sandbox checks.

NET dropper" and ".NET downloader" referred in a report last year by MalwareBytes analysts about a downloader they called "Saint Bot" were DarkTortilla's initial and loader and core processor components that were overlooked in the report. "As a result, these crypters are often overlooked by security researchers in favor of their main payload given the high cost and low reward that reverse engineering the crypter would likely result in," Pantazopoulos said. In addition, many of these malwares are encoded using code obfuscators like ConfuserEX, DeapSea, and Eazfuscator. NET-based crypters, loaders, and droppers in the wild. Rob Pantazopoulos, senior security researcher with the CTU, told The Register that it's unusual for malware like DarkTortilla to be active for so long and not be detected, but that it was helped by being among a number of generic.
