Sality is a highly sophisticated malware known for infecting executable files and rapidly spreading across networks. It primarily creates a peer-to-peer botnet that is used for malicious activities such as spamming, data theft, and downloading additional malware. Sality has strong persistence mechanisms, including disabling security software, making it difficult to remove. Its ability to spread quickly and silently, along with its polymorphic nature, allows it to evade detection by traditional antivirus solutions.

Trojans are a group of malicious programs distinguished by their ability to masquerade as benign software. Depending on their type, trojans possess a variety of capabilities, ranging from maintaining full remote control over the victim’s machine to stealing data and files, as well as dropping other malware. At the same time, the main functionality of each trojan family can differ significantly depending on its type. The most common trojan infection chain starts with a phishing email.
