"What this means in practical terms is that PLATINUM was able to abuse this feature to hide their backdoor from the behavioral sensors of many host security products. One of the first techniques that attackers use to avoid antivirus detection is compression. "Using hotpatching in a malicious context is a technique that can be used to avoid being detected, as many antimalware solutions monitor non-system processes for regular injection methods, such as CreateRemoteThread," the Microsoft researchers said in a blog post. This is the first time that the Microsoft researchers have seen the technique used in the wild by malicious attackers. And it is his technique that the Platinum group uses. The potential use of hotpatching as a stealth way to inject malicious code into running processes was described by security researcher Alex Ionescu at the SyScan security conference in 2013. During the 12-year support life of Windows Server 2003, only 10 patches used this technique. Hotpatching was removed in Windows 8 and later versions, because it was rarely used. This leverages a somewhat obscure feature that was first introduced in Windows Server 2003 and allows the dynamic updating of system components without the need to reboot the computer. One of the more interesting techniques used by the group is known as hotpatching. BlackBerrys team says that first-stage droppers and loaders are becoming more common in order to avoid detection on a target endpoint, and once the malware has circumvented existing security. While the Microsoft researchers stopped short of saying with certainty that Platinum is a state-sponsored cyberespionage group, they said that "the group shows traits of being well funded, organized, and focused on information that would be of most use to government bodies." Its custom malware components have self-deletion capabilities and are designed to run only during the victims' working hours, to hide their activity among regular user traffic, Microsoft's Windows Defender Advanced Threat Hunting team said in a report. customized to avoid detection, provides a remote attacker with. This vector of attack is difficult to detect, but. The infected file contained malware that used a zero- day exploit in Adobe Flash software. It is a method which can conceal malware from detecting by both static and dynamic detection methods 7. A malicious program that is typically injected into some running process, and executes ONLY MALWARE in RAM. Concealment.Some malware has as its primary trait avoiding detection by concealing itspresencefrom software scanners that are looking for malware. Packers are very popular amongst malware creators. This study incorporates deep learning algorithms to avoid the feature. This way the known malware may seem like a new one and may be able to avoid detection. To achieve this, it launches only a small number of attack campaigns every year. These existing malware detection tools, which employ static and dynamic analysis.
