It was never a question of "if" but "when". After five months of absence, the dreaded [Emotet]() has returned. Following several false alarms over the last few weeks, a [spam ]()campaign was [first spotted]() on July 13 showing signs of a likely comeback. The [Emotet ]()botnets started pushing [malspam]() actively on Friday, July 17, using the same techniques as employed in its last wave of activity. Malicious emails contain either a URL or an attachment that, once clicked on or opened, launches the Emotet payload. One familiar technique is for the document to be sent as a reply within existing email threads. [![Emotet malicious emails with document attachment](https://blog.malwarebytes.com/wp-content/uploads/2020/07/emotet_email.png)]( "" ) The document contains a heavily obfuscated macro: [![Emotet malware hidden in word document macro](https://blog.malwarebytes.com/wp-content/uploads/2020/07/macro.png)]( "" ) Once the macro is enabled, WMI launches PowerShell to retrieve the Emotet binary from one of the remote compromised websites. It will iterate through a list until it identifies one that is responding.

One of the reasons why it was (and is) so successful is because of its constant evolution in attack techniques and threat partnerships. For example, according to [Bleeping Computer](), Emotet now uses stolen email attachments to add credibility to the spam it generates to infect targeted systems. This is in addition to the aforementioned technique of hijacking email threads—a [social engineering]() strategy employed to increase the likelihood of infection. Emotet is used by cybercriminals as the initial entry point for infecting an organization, followed by a dwell time that can last days or weeks. In the meantime, it often drops secondary payloads to further penetrate its target's defenses. In its most recent incarnation, Emotet has been observed dropping secondary payloads, such as [TrickBot]() and [QakBot]() to spread laterally and steal credentials. In fact, the real damage caused by an Emotet compromise happens when it forms alliances with other malware gangs—particularly with those threat actors interested in dropping ransomware, such as [Ryuk](), which was a constant partner of Emotet's in 2019. So far, a prevalent ransomware family has not yet been identified in Emotet's latest campaign. ### How to protect against Emotet Users looking to protect against Emotet should first keep a wary eye out for phishing and/or spam emails—especially any emails with attachments. Even emails that appear to be from known contacts should be treated with suspicion. However, if unlucky users happen to click on a malicious URL or open an infected document, a [good security program]()—especially one with anti-exploit technology—will block the malware from launching and keep computers free from infection. For more information on how to protect against or remediate an Emotet infection, take a look at [our emergency kit](), which includes a summary of the threat and a checklist of tips.
