Query: explain T1667 Email Bombing
Matching passage: T1667 Email Bombing. Tactics: impact. Description: Adversaries may flood targeted email addresses with an overwhelming volume of messages. This may bury legitimate emails in a flood of spam and disrupt business operations.(Citation: sophos-bombing)(Citation: krebs-email-bombing) An adversary may accomplish email bombing by leveraging an automated bot to register a targeted address for e-mail lists that do not validate new signups, such as online newsletters. The result can be a wave of thousands of e-mails that effectively overloads the victim’s inbox.(Citation: krebs-email-bombing)(Citation: hhs-email-bombing) By sending hundreds or thousands of e-mails in quick succession, adversaries may successfully divert attention away from and bury legitimate messages including security alerts, daily business processes like help desk tickets and client correspondence, or ongoing scams.(Citation: hhs-email-bombing) This behavior can also be used as a tool of harassment.(Citation: krebs-email-bombing) This behavior may be a precursor for [Spearphishing Voice](https://attack.mitre.org/techniques/T1566/004). For example, an adversary may email bomb a target and then follow up with a phone call to fraudulently offer assistance. This social engineering may lead to the use of [Remote Access Software](https://attack.mitre.org/techniques/T1663) to steal credentials, deploy ransomware, conduct [Financial Theft](https://attack.mitre.org/techniques/T1657)(Citation: sophos-bombing), or engage in other malicious activity.(Citation: rapid7-email-bombing)
Near-miss passage: T1489 Service Stop. Tactics: impact. Description: Adversaries may stop or disable services on a system to render those services unavailable to legitimate users. Stopping critical services or processes can inhibit or stop response to an incident or aid in the adversary's overall objectives to cause damage to the environment.(Citation: Talos Olympic Destroyer 2018)(Citation: Novetta Blockbuster) Adversaries may accomplish this by disabling individual services of high importance to an organization, such as <code>MSExchangeIS</code>, which will make Exchange content inaccessible.(Citation: Novetta Blockbuster) In some cases, adversaries may stop or disable many or all services to render systems unusable.(Citation: Talos Olympic Destroyer 2018) Services or processes may not allow for modification of their data stores while running. Adversaries may stop services or processes in order to conduct [Data Destruction](https://attack.mitre.org/techniques/T1485) or [Data Encrypted for Impact](https://attack.mitre.org/techniques/T1486) on the data stores of services like Exchange and SQL Server, or on virtual machines hosted on ESXi infrastructure.(Citation: SecureWorks WannaCry Analysis)(Citation: Crowdstrike Hypervisor Jackpotting Pt 2 2021) Threat actors may also disable or stop service in cloud environments. For example, by leveraging the `DisableAPIServiceAccess` API in AWS, a threat actor may prevent the service from creating service-linked roles on new accounts in the AWS Organization.(Citation: Datadog Security Labs Cloud Persistence 2025)(Citation: AWS DisableAWSServiceAccess)
