Many malware strains have become cross-functionally adaptive, as noted in the 2023 End of Year Threat Report. This comprises the combination of information-stealing malware with malware loaders like remote access trojans (RATs).
The menace of malware-as-a-service
Researchers at Darktrace discovered that “malware strains are progressively developed with a minimum of two functions and are interoperable with a greater number of existing tools” through reverse engineering and detection analysis.
Because these malicious tools may gather passwords and data without compromising files, which makes detection more difficult, they pose a special risk to enterprises.
One well-known instance of this was the information-stealing and remote access Trojan (RAT) called ViperSoftX, which was designed to obtain sensitive data such as Bitcoin wallet addresses and passwords kept in password managers or browsers.
2020 saw the first recorded sighting of ViperSoftX in the wild, however, strains discovered in 2022 and 2023 have more advanced detection evasion strategies and capabilities.
Another instance is the ransomware known as Black Basta, which spreads the Qbot banking virus to steal credentials.
