Query: threat report mentioning Clear Mailbox Data
Matching passage: T1070.008 Clear Mailbox Data. Tactics: stealth. Description: Adversaries may modify mail and mail application data to remove evidence of their activity. Email applications allow users and other programs to export and delete mailbox data via command line tools or use of APIs. Mail application data can be emails, email metadata, or logs generated by the application or operating system, such as export requests. Adversaries may manipulate emails and mailbox data to remove logs, artifacts, and metadata, such as evidence of [Phishing](https://attack.mitre.org/techniques/T1566)/[Internal Spearphishing](https://attack.mitre.org/techniques/T1534), [Email Collection](https://attack.mitre.org/techniques/T1114), [Mail Protocols](https://attack.mitre.org/techniques/T1071/003) for command and control, or email-based exfiltration such as [Exfiltration Over Alternative Protocol](https://attack.mitre.org/techniques/T1048). For example, to remove evidence on Exchange servers adversaries have used the <code>ExchangePowerShell</code> [PowerShell](https://attack.mitre.org/techniques/T1059/001) module, including <code>Remove-MailboxExportRequest</code> to remove evidence of mailbox exports.(Citation: Volexity SolarWinds)(Citation: ExchangePowerShell Module) On Linux and macOS, adversaries may also delete emails through a command line utility called <code>mail</code> or use [AppleScript](https://attack.mitre.org/techniques/T1059/002) to interact with APIs on macOS.(Citation: Cybereason Cobalt Kitty 2017)(Citation: mailx man page) Adversaries may also remove emails and metadata/headers indicative of spam or suspicious activity (for example, through the use of organization-wide transport rules) to reduce the likelihood of malicious emails being detected by security products.(Citation: Microsoft OAuth Spam 2022)
Near-miss passage: T1070.010 Relocate Malware. Tactics: stealth. Description: Once a payload is delivered, adversaries may reproduce copies of the same malware on the victim system to remove evidence of their presence and/or avoid defenses. Copying malware payloads to new locations may also be combined with [File Deletion](https://attack.mitre.org/techniques/T1070/004) to cleanup older artifacts. Relocating malware may be a part of many actions intended to evade defenses. For example, adversaries may copy and rename payloads to better blend into the local environment (i.e., [Match Legitimate Resource Name or Location](https://attack.mitre.org/techniques/T1036/005)).(Citation: DFIR Report Trickbot June 2023) Payloads may also be repositioned to target [File/Path Exclusions](https://attack.mitre.org/techniques/T1564/012) as well as specific locations associated with establishing [Persistence](https://attack.mitre.org/tactics/TA0003).(Citation: Latrodectus APR 2024) Relocating malicious payloads may also hinder defensive analysis, especially to separate these payloads from earlier events (such as [User Execution](https://attack.mitre.org/techniques/T1204) and [Phishing](https://attack.mitre.org/techniques/T1566)) that may have generated alerts or otherwise drawn attention from defenders. Moving payloads into target directories does not alter the Creation timestamp, thereby evading detection logic reliant on modifications to this artifact (i.e., [Timestomp](https://attack.mitre.org/techniques/T1070/006)).
