That way, you can see how exploit protection affects apps your organization is using.Ĭustomize exploit protection PowerShell cmdlets for exploit protectionĬonfigure attack surface reduction rules with PowerShell You can use PowerShell to exclude files and folders from attack surface reduction rules.Ĭustomize attack surface reduction rules: Use PowerShell to exclude files & folders Also, see António Vasconcelo's graphical user interface tool for setting attack surface reduction rules with PowerShell.Įnable Network Protection with PowerShell You can use PowerShell to enable Network Protection. Use PowerShell cmdlets to configure and manage Microsoft Defender Antivirus Use PowerShell cmdlets to enable cloud-delivered protectionĬonfigure exploit protection to mitigate threats on your organization's devices We recommend using exploit protection in audit mode at first. Manage Microsoft Defender Antivirus View status of antimalware protection, configure preferences for antivirus scans & updates, and make other changes to your antivirus protection.* You can use PowerShell to manage Microsoft Defender Antivirus, exploit protection, and your attack surface reduction rules. Configure Microsoft Defender for Endpoint with PowerShell More intricate details are offered in Carbon Black's 'PowerShell' Deep Dive report, available for download.Threat protection features that you configure by using PowerShell, WMI, or MCPmdRun.exe can be overwritten by configuration settings that are deployed with Intune or Configuration Manager. One of the most recent PowerShell-based malware families is the PowerWare ransomware. "Unlike other common technologies such as Java and Adobe Flash, which IT administrators can more easily remove or ban, many organizations and applications rely on PowerShell to manage their critical systems." Detecting PowerShell malware is as impractical as banning PowerShellīecause PowerShell is a ubiquitous technology within the Windows ecosystem, detecting PowerShell-based malware is almost impossible, since there's no technical method of distinguishing between good and malicious PowerShell source code.įor this reason, security researchers expect PowerShell to become a prevalent technology in malware design, but also because toolkits like PowerSploit, PowerShell Empire, p0wnedShell, and the Social-Engineer Toolkit are making it easier to use PowerShell exploits out of the box.Īs for blocking PowerShell, security researchers say this is impractical. Respondents said that, most of the time, the PowerShell-based malware was distributed via social engineering techniques and that it targeted mostly corporate networks and financial data, aiming to steal information or disrupt services. In 87 percent of cases, the PowerShell malware was part of a shotgun approach, while for the rest, the malware was part of a targeted attack, specific to hacker groups and state-sponsored actors.īy shotgun approach malware, we mean common malware such as ransomware, click fraud bots, and other threats where the attacker doesn't care whom they infect as long as they infect someone.Ĭarbon Black claims that over half of these incidents were related to Vawtrack, a banking trojan that heavily uses PowerShell in its source code. PowerShell, a favorite tool for targeted attacks and commodity malware Respondents said that, in 31 percent of all the situations, their clients reported not receiving any warnings about the ongoing attacks. Microsoft's PowerShell task automation framework is becoming one of the most popular tools for coding and enhancing malware, a Carbon Black study has discovered.Īggregating data from over 1,100 separate investigations from 20 security firms, Carbon Black says that PowerShell was used in 38 percent of all the attacks they analyzed.
