AdvIntel's State of Emotet aka "SpmTools" Displays Over Million Compromised Machines Through 2022
Throughout 2022, AdvIntel observed 1,267,598 total Emotet infections worldwide. Significant peaks in activity occurred between February/March, notably kicking off during the start of the Russian-Ukrainian conflict at the end of February, and between June/July; attributed to Emotet’s usage alongside post-Conti groups such as Quantum and BlackCat.
It is notable that the most Emotet-targeted country is the United States, making up 35.7% of the dataset, with Finland (10.3%), Brazil (9.9%), The Netherlands (9.4%), and France (7.7%) in the remaining top placements.
The Emotet botnet (also known as SpmTools) has fueled major cybercriminal groups as an initial attack vector, or precursor, for numerous ongoing attacks. From November 2021 to Conti’s dissolution in June 2022, Emotet was an exclusive Conti ransomware tool, however, the Emotet infection chain is currently attributed to Quantum and BlackCat.
Emotet is a botnet of Eastern European origin that was originally designed as a banking trojan, meant to steal sensitive banking information by intercepting internet traffic. However, updates to Emotet over time have significantly increased the threat that it poses, and it has evolved into a prominent, invasive malware loader, largely due to its ability to conduct a full infection cycle and seamlessly spread other types of malware. Since its appearance in 2014, Emotet has proved to be a consistent and highly threatening malware that has targeted individuals, companies, municipalities, and governments alike.
The observed botnet taxonomy attacker flow for Emotet is Emotet -> Cobalt Strike -> Ransomware Operation. What this means is that currently, the way that threat actors primarily utilize Emotet is as a dropper, or downloader for a Cobalt Strike beacon, which deploys a payload allowing threat actors to take over networks and execute ransomware operations.

Threat actors that were previously affiliated with the Conti group continue to utilize its toolkit, which includes the Emotet botnet.

Emotet Patterns [MITRE ATT&CK Framework]:
The following techniques (framed within MITRE ATT&CK categorizations) are a small sample of those utilized by Emotet (for a full list, click here).
Emotet may attempt to get a listing of email addresses and accounts, or dump Exchange address lists such as global address lists (GALs).
With no prior knowledge of legitimate credentials within the system or environment, Emotet may guess passwords to attempt access to the account.
Emotet may acquire credentials from web browsers by reading files specific to the target browser.
Emotet may target user email on local systems to collect sensitive information.
Adversaries may steal data by exfiltrating it over an existing command and control channel.
Emotet may inject dynamic-link libraries (DLLs) into processes in order to evade process-based defenses as well as possibly elevate privileges.
Emotet may rely upon a user opening a malicious file in order to gain execution. Users may be subjected to social engineering to get them to open a file that will lead to code execution.
