Emotet is a malware household lively since 2014, operated by a cybercrime group referred to as Mealybug or TA542. Though it began as a banking trojan, it later developed right into a botnet that turned probably the most prevalent threats worldwide. Emotet spreads through spam emails; it might exfiltrate info from, and ship third-party malware to, compromised computer systems. Emotet operators should not very choosy about their targets, putting in their malware on methods belonging to people in addition to corporations and larger organizations.
In January 2021, Emotet was the goal of a takedown on account of a world, collaborative effort of eight nations coordinated by Eurojust and Europol. Nonetheless, regardless of this operation, Emotet got here again to life in November 2021.
Key factors of this blogpost:
Emotet launched a number of spam campaigns because it re-appeared after its takedown.
Since then, Mealybug created a number of new modules and a number of instances up to date and improved all present modules.
Emotet operators subsequently have put a number of effort into avoiding monitoring and monitoring of the botnet because it got here again.
At present Emotet is silent and inactive, most likely attributable to failing to seek out an efficient, new assault vector.
Determine 1. Timeline of attention-grabbing Emotet occasions since its return
Spam campaigns
After the comeback adopted by a number of spam campaigns on the finish of 2021, the start of 2022 continued with these traits and we registered a number of spam campaigns launched by Emotet operators. Throughout this time Emotet was spreading primarily through malicious Microsoft Phrase and Microsoft Excel paperwork with embedded VBA macros.
In July 2022, Microsoft modified the sport for all of the malware households like Emotet and Qbot – which had used phishing emails with malicious doc as the tactic of spreading – by disabling VBA macros in paperwork obtained from the Web. This variation was introduced by Microsoft originally of the 12 months and deployed initially in early April, however the replace was rolled again attributable to consumer suggestions. The ultimate rollout got here on the finish of July 2022 and, as might be seen in Determine 2, the replace resulted in a major drop in Emotet compromises; we didn’t observe any vital exercise through the summer season of 2022.
Determine 2. Emotet detection development, seven-day transferring common
Disabling Emotet’s essential assault vector made its operators search for new methods to compromise their targets. Mealybug began experimenting with malicious LNK and XLL information, however when the 12 months 2022 was ending, Emotet operators struggled to discover a new assault vector that may be as efficient as VBA macros had been. In 2023, they ran three distinctive malspam campaigns, every testing a barely completely different intrusion avenue and social engineering approach. Nonetheless, the shrinking measurement of the assaults and fixed modifications within the method might counsel dissatisfaction with the outcomes.
The primary of these three campaigns occurred round March eighth, 2023, when the Emotet botnet began distributing Phrase paperwork, masked as invoices, with embedded malicious VBA macros. This was fairly odd as a result of VBA macros had been disabled by Microsoft by default, so victims couldn’t run embedded malicious code.
Of their second marketing campaign between March thirteenth and March 18th, the attackers seemingly acknowledged these flaws, and aside from utilizing the reply chain method, in addition they switched from VBA macros to OneNote information (ONE) with embedded VBScripts. If the victims opened the file, they had been greeted by what seemed like a protected OneNote web page, asking them to click on a View button to see the content material. Behind this graphic factor was a hidden VBScript, set to obtain the Emotet DLL.
Regardless of a OneNote warning that this motion would possibly result in malicious content material, folks are likely to click on at related prompts by behavior and thus can doubtlessly enable the attackers to compromise their gadgets.
The final marketing campaign noticed in ESET telemetry was launched on March twentieth, profiting from the upcoming revenue tax due date in the US. The malicious emails despatched by the botnet pretended to return from the US tax workplace Inner Income Service (IRS) and carried an connected archive file named W-9 type.zip. The included ZIP file contained a Phrase doc with an embedded malicious VBA macro that the meant sufferer most likely needed to allow. Aside from this marketing campaign, focused particularly to the USA, we additionally noticed one other marketing campaign utilizing embedded VBScripts and OneNote method that was underway on the identical time.
As might be seen in Determine 3, a lot of the assaults detected by ESET had been geared toward Japan (43%), Italy (13%), though these numbers could also be biased by the robust ESET consumer base in these areas. After eradicating these prime two nations (so as to deal with the remainder of the world), in Determine 4 it may be seen that the remainder of the world was additionally hit, with Spain (5%) in third place adopted by Mexico (5%) and South Africa (4%).

Enhanced safety and obfuscations
After its reappearance, Emotet received a number of upgrades. The primary notable function is that the botnet switched its cryptographic scheme. Earlier than the takedown, Emotet used RSA as their main uneven scheme and after the reappearance, the botnet began to make use of Elliptic curve cryptography. At present each Downloader module (additionally referred to as Foremost module) comes with two embedded public keys. One is used for the Elliptic curve Diffie Hellman key trade protocol and the opposite is used for a signature verification – Digital signature algorithm.
Aside from updating Emotet malware to 64-bit structure, Mealybug has additionally applied a number of new obfuscations to guard their modules. First notable obfuscation is management circulate flattening which might considerably decelerate evaluation and finding attention-grabbing components of code in Emotet’s modules.
Mealybug additionally applied and improved its implementation of many randomization strategies, of which essentially the most notable are the randomization of order of construction members and the randomization of directions that calculate constants (constants are masked).
Another replace that’s value mentioning occurred over the past quarter of 2022, when modules began utilizing timer queues. With these, the principle perform of modules and the communication a part of modules had been set as a callback perform, which is invoked by a number of threads and all of that is mixed with the management circulate flattening, the place the state worth that manages which block of code is to be invoked is shared among the many threads. This obfuscation provides as much as one other impediment in evaluation and makes following of the execution circulate much more troublesome.
New modules
To stay worthwhile and prevalent malware, Mealybug applied a number of new modules, proven in yellow in Determine 5. A few of them had been created as a defensive mechanism for the botnet, others for extra environment friendly spreading of the malware, and final however not least, a module that steals info that can be utilized to steal the sufferer’s cash.
Determine 5. Emotet’s most incessantly used modules. Crimson existed earlier than the takedown; yellow appeared after the comeback
Thunderbird Electronic mail Stealer and Thunderbird Contact Stealer
Emotet is unfold through spam emails and folks usually belief these emails, as a result of Emotet efficiently makes use of an e-mail thread hijacking approach. Earlier than the takedown, Emotet used modules we name Outlook Contact Stealer and Outlook Electronic mail Stealer, that had been able to stealing emails and make contact with info from Outlook. However as a result of not everybody makes use of Outlook, after the takedown Emotet centered additionally on a free different e-mail software – Thunderbird.
Emotet might deploy a Thunderbird Electronic mail Stealer module to the compromised pc, which (because the identify suggests) is able to stealing emails. The module searches by way of the Thunderbird information containing obtained messages (in MBOX format) and steals information from a number of fields together with sender, recipients, topic, date, and contents of the message. All stolen info is then despatched to a C&C server for additional processing.
Along with Thunderbird Electronic mail Stealer, Emotet additionally deploys a Thunderbird Contact Stealer, which is able to stealing contact info from Thunderbird. This module additionally searches by way of the Thunderbird information, this time in search of each obtained and despatched messages. The distinction is that this module simply extracts info from the From:, To:, CC: and Cc: fields and creates an inside graph of who communicated with whom, the place nodes are folks, and there may be an edge between two folks in the event that they communicated with one another. Within the subsequent step, the module orders the stolen contacts – beginning with essentially the most interconnected folks – and sends this info to a C&C server.
All this effort is complemented by two further modules (that existed already earlier than the takedown) – the MailPassView Stealer module and the Spammer module. MailPassView Stealer abuses a professional NirSoft instrument for password restoration and steals credentials from e-mail purposes. When stolen emails, credentials, and details about who’s involved with whom will get processed, Mealybug creates malicious emails that appear like a reply to beforehand stolen conversations and sends these emails along with the stolen credentials to a Spammer module that makes use of these credentials to ship malicious replies to earlier e-mail conversations through SMTP.
Google Chrome Credit score Card Stealer
Because the identify suggests, Google Chrome Credit score Card Stealer steals details about bank cards saved within the Google Chrome browser. To realize this, the module makes use of a statically linked SQLite3 library for accessing the Internet Knowledge database file often positioned in %LOCALAPPDATApercentGoogleChromeUser DataDefaultWeb Knowledge. The module queries the desk credit_cards for name_of_card, expiration_month, expiration_year, and card_number_encrypted, containing details about bank cards saved within the default Google Chrome profile. Within the final step, the card_number_encrypted worth is decrypted utilizing the important thing saved within the %LOCALAPPDATApercentGoogleChromeUser DataLocal State file and all info is shipped to a C&C server.
Systeminfo and Hardwareinfo modules
Shortly after the return of Emotet, in November 2021 a brand new module we name Systeminfo appeared. This module collects details about a compromised system and sends it to the C&C server. Data collected consists of:
Output of the systeminfo command
Output of the ipconfig /all command
Output of the nltest /dclist: command (eliminated in Oct. 2022)
Course of listing
Uptime (obtained through GetTickCount) in seconds (eliminated in Oct 2022)
In October 2022 Emotet’s operators launched one other new module we name Hardwareinfo. Regardless that it doesn’t steal solely details about the {hardware} of a compromised machine, it serves as a complementary supply of knowledge to the Systeminfo module. This module collects the next information from the compromised machine:
Laptop identify
Username
OS model info, together with main and minor model numbers
Session ID
CPU model string
Details about RAM measurement and utilization
Each modules have one main objective – confirm whether or not the communication comes from legitimately compromised sufferer or not. Emotet was, particularly after its comeback, a very sizzling subject within the pc safety trade and amongst researchers, so Mealybug went to nice lengths to guard themselves from monitoring and monitoring of their actions. Due to the data collected by these two modules that not solely accumulate information, but in addition comprise anti-tracking and anti-analysis tips, Mealybug’s capabilities to inform aside actual victims from malware researchers’ actions or sandboxes had been considerably improved.
What’s subsequent?
Based on ESET analysis and telemetry, each Epochs of the botnet have been quiet for the reason that starting of the April 2023. At present it stays unclear if that is one more trip time for the authors, in the event that they battle to seek out new efficient an infection vector, or if there may be somebody new working the botnet.
Regardless that we can not affirm the rumors that one or each Epochs of the botnet had been offered to any person in January 2023, we observed an uncommon exercise on one of many Epochs. The most recent replace of the downloader module contained a brand new performance, which logs the inside states of the module and tracks its execution to a file C:JSmithLoader (Determine 6, Determine 7). As a result of this file must be present to really log one thing, this performance appears like a debugging output for somebody who doesn’t fully perceive what the module does and the way it works. Moreover, at the moment the botnet was additionally extensively spreading Spammer modules, that are thought of to be extra treasured for Mealybug as a result of traditionally they used these modules solely on machines that had been thought of by them to be secure.

Determine 7. Logging of conduct of the downloader module
Whichever rationalization of why the botnet is quiet now could be true, Emotet has been identified for its effectiveness and its operators made an effort to rebuild and keep the botnet and even add some enhancements, so preserve monitor with our weblog to see what the long run will carry us.
