Query: intelligence brief on T1137.006
Matching passage: T1137.006 Add-ins. Tactics: persistence. Description: Adversaries may abuse Microsoft Office add-ins to obtain persistence on a compromised system. Office add-ins can be used to add functionality to Office programs. (Citation: Microsoft Office Add-ins) There are different types of add-ins that can be used by the various Office products; including Word/Excel add-in Libraries (WLL/XLL), VBA add-ins, Office Component Object Model (COM) add-ins, automation add-ins, VBA Editor (VBE), Visual Studio Tools for Office (VSTO) add-ins, and Outlook add-ins. (Citation: MRWLabs Office Persistence Add-ins)(Citation: FireEye Mail CDS 2018) Add-ins can be used to obtain persistence because they can be set to execute code when an Office application starts.
Near-miss passage: T1137 Office Application Startup. Tactics: persistence. Description: Adversaries may leverage Microsoft Office-based applications for persistence between startups. Microsoft Office is a fairly common application suite on Windows-based operating systems within an enterprise network. There are multiple mechanisms that can be used with Office for persistence when an Office-based application is started; this can include the use of Office Template Macros and add-ins. A variety of features have been discovered in Outlook that can be abused to obtain persistence, such as Outlook rules, forms, and Home Page.(Citation: SensePost Ruler GitHub) These persistence mechanisms can work within Outlook or be used through Office 365.(Citation: TechNet O365 Outlook Rules)

Query: adversary uses Malvertising
Matching passage: T1583.008 Malvertising. Tactics: resource development. Description: Adversaries may purchase online advertisements that can be abused to distribute malware to victims. Ads can be purchased to plant as well as favorably position artifacts in specific locations online, such as prominently placed within search engine results. These ads may make it more difficult for users to distinguish between actual search results and advertisements.(Citation: spamhaus-malvertising) Purchased ads may also target specific audiences using the advertising network’s capabilities, potentially further taking advantage of the trust inherently given to search engines and popular websites. Adversaries may purchase ads and other resources to help distribute artifacts containing malicious code to victims. Purchased ads may attempt to impersonate or spoof well-known brands. For example, these spoofed ads may trick victims into clicking the ad which could then send them to a malicious domain that may be a clone of official websites containing trojanized versions of the advertised software.(Citation: Masquerads-Guardio)(Citation: FBI-search) Adversary’s efforts to create malicious domains and purchase advertisements may also be automated at scale to better resist cleanup efforts.(Citation: sentinelone-malvertising) Malvertising may be used to support [Drive-by Target](https://attack.mitre.org/techniques/T1608/004) and [Drive-by Compromise](https://attack.mitre.org/techniques/T1189), potentially requiring limited interaction from the user if the ad contains code/exploits that infect the target system's web browser.(Citation: BBC-malvertising) Adversaries may also employ several techniques to evade detection by the advertising network. For example, adversaries may dynamically route ad clicks to send automated crawler/policy enforcer traffic to benign sites while validating potential targets then sending victims referred from real ad clicks to malicious pages. This infection vector may therefore remain hidden from the ad network as well as any visitor not reaching th
Near-miss passage: T1583.003 Virtual Private Server. Tactics: resource development. Description: Adversaries may rent Virtual Private Servers (VPSs) that can be used during targeting. There exist a variety of cloud service providers that will sell virtual machines/containers as a service. By utilizing a VPS, adversaries can make it difficult to physically tie back operations to them. The use of cloud infrastructure can also make it easier for adversaries to rapidly provision, modify, and shut down their infrastructure. Acquiring a VPS for use in later stages of the adversary lifecycle, such as Command and Control, can allow adversaries to benefit from the ubiquity and trust associated with higher reputation cloud service providers. Adversaries may also acquire infrastructure from VPS service providers that are known for renting VPSs with minimal registration information, allowing for more anonymous acquisitions of infrastructure.(Citation: TrendmicroHideoutsLease)
