Query: mitigate Upload Malware
Matching passage: T1608.001 Upload Malware. Tactics: resource development. Description: Adversaries may upload malware to third-party or adversary controlled infrastructure to make it accessible during targeting. Malicious software can include payloads, droppers, post-compromise tools, backdoors, and a variety of other malicious content. Adversaries may upload malware to support their operations, such as making a payload available to a victim network to enable [Ingress Tool Transfer](https://attack.mitre.org/techniques/T1105) by placing it on an Internet accessible web server. Malware may be placed on infrastructure that was previously purchased/rented by the adversary ([Acquire Infrastructure](https://attack.mitre.org/techniques/T1583)) or was otherwise compromised by them ([Compromise Infrastructure](https://attack.mitre.org/techniques/T1584)). Malware can also be staged on web services, such as GitHub or Pastebin; hosted on the InterPlanetary File System (IPFS), where decentralized content storage makes the removal of malicious files difficult; or saved on the blockchain as smart contracts, which are resilient against takedowns that would affect traditional infrastructure.(Citation: Volexity Ocean Lotus November 2020)(Citation: Talos IPFS 2022)(Citation: Guardio Etherhiding 2023)(Citation: Bleeping Computer Binance Smart Chain 2023) Adversaries may upload backdoored files, such as software packages, application binaries, virtual machine images, or container images, to third-party software stores, package libraries, extension marketplaces, or repositories (ex: GitHub, CNET, AWS Community AMIs, Docker Hub, PyPi, NPM).(Citation: Datadog Security Labs Malicious PyPi Packages 2024) By chance encounter, victims may directly download/install these backdoored files via [User Execution](https://attack.mitre.org/techniques/T1204). Masquerading, including typosquatting legitimate software, may increase the chance of users mistakenly executing these files.
Near-miss passage: T1608.002 Upload Tool. Tactics: resource development. Description: Adversaries may upload tools to third-party or adversary controlled infrastructure to make it accessible during targeting. Tools can be open or closed source, free or commercial. Tools can be used for malicious purposes by an adversary, but (unlike malware) were not intended to be used for those purposes (ex: [PsExec](https://attack.mitre.org/software/S0029)). Adversaries may upload tools to support their operations, such as making a tool available to a victim network to enable [Ingress Tool Transfer](https://attack.mitre.org/techniques/T1105) by placing it on an Internet accessible web server. Tools may be placed on infrastructure that was previously purchased/rented by the adversary ([Acquire Infrastructure](https://attack.mitre.org/techniques/T1583)) or was otherwise compromised by them ([Compromise Infrastructure](https://attack.mitre.org/techniques/T1584)).(Citation: Dell TG-3390) Tools can also be staged on web services, such as an adversary controlled GitHub repo, or on Platform-as-a-Service offerings that enable users to easily provision applications.(Citation: Dragos Heroku Watering Hole)(Citation: Malwarebytes Heroku Skimmers)(Citation: Intezer App Service Phishing) Adversaries can avoid the need to upload a tool by having compromised victim machines download the tool directly from a third-party hosting location (ex: a non-adversary controlled GitHub repo), including the original hosting site of the tool.
