According to the cybersecurity researchers, several fresh techniques, comparatively advanced — are being used by attackers, for exploiting legitimate Windows services to accelerate low-level privileges into the system (concept and practice of restricting access rights for users, accounts, and computing processes to only those resources required to perform routine, legitimate activities, least privilege is also a foundational component of zero trust strategies) to get full control of the system.
By the means of this recent attack, the threat actors took the same advantages, targeting similar Windows services facilities as that of previous attacks. Meanwhile, threat actors are also working on some new techniques to get access to the recent version of the operating system, as reported by Antonio Cocomazzi, a system engineer at SentinelOne. Furthermore, Antonio Cocomazzi shed light on the same in a Black Hat Asian virtual conference this week.
For the organizations, the biggest issue dealing with these cyberattacks is that these attacks exploit services that hold a very important part of the system as well as exist by design in the windows functioning system. These services are enabled and available by default into the system as well as they play an essential part in the implementation of Web networking, mail servers, database servers, and other important services.
Exploits, named “juicy potatoes,” has become a mainstream method for threat actors to invade into the windows systems, said Cocoazzi.
Further, he added that SentinelOne has disclosed some very specific evidence against this exploit: it is being used in multiple APT campaigns.
“Microsoft has fixed the exploit in newer versions of its software. However, JuicyPotato still works on every updated Windows Server until version 2016 and on every updated Windows Client machine until version 10, build 1803. Additionally, newer versions of the so-called Potato family of exploits — such as RoguePotato and Juicy 2 — are now available that bypass the Microsoft fix that shut down JuicyPotato.” Antonio Cocomazzi, a system engineer at SentinelOne reported.
