# Threat analysis: The emergent URSA trojan impacts many countries using a sophisticated loader **[seguranca-informatica.pt/threat-analysis-the-emergent-ursa-trojan-impacts-many-countries-using-a-sophisticated-loader/](https://seguranca-informatica.pt/threat-analysis-the-emergent-ursa-trojan-impacts-many-countries-using-a-sophisticated-loader/)** September 15, 2020 **Threat analysis: The emergent URSA trojan – and also known as mispadu malware by ESET – impacts many** **countries using a sophisticated loader.** [Since last June 2020, a new wave of the URSA trojan – a derivation and also known as mispadu malware by ESET](https://www.welivesecurity.com/2019/11/19/mispadu-advertisement-discounted-unhappy-meal/) – has affected users from several countries, including Bolivia, Chile, Mexico, Argentina, Ecuador, Peru, **Colombia, Paraguay, Costa Rica, Brazil, Spain, Italy, and Portugal. This malware is a trojan malware, and when** installed on the victim’s devices, it collects passwords from browsers and from popular software such as FTP and email services and also performs banking browser overlay to lure the victims to introduce the banking credentials while the flow is executed – step-by-step – in the background by criminals. Below, a geographic representation of the number of infections between June and mid-September 2020 around the world according to Table 1. ## URSA trojan – Geomap of Infections ### June – mid-September 2020 **_Table 1: URSA trojan – infections by country between June and mid-September 2020._** In total, 3.379 users were impacted by this threat from June – mid-September 2020 according to data obtained from some C2s this wave. With a total of 1977 infections, Mexico is the country with more users affected, followed by **Spain – 631 victims, Portugal – 514, and Chile – 331.** It is important to realize that the number of infections may have been much higher, as these indicators are only related to the data existing in some of the C2s presented at the end of the article. For example, no infections have been identified in Italy, which cannot be true. ## How URSA trojan spreads ----- URSA malware is a relatively recent trojan and aims to steal credentials from victims machines and to create **banking overlay windows when the victim visits their home banking portals. URSA is propagated via social** engineering schemas – namely, phishing/malscam campaigns. In Portugal, the threat has been disseminated inthe-wild and impersonating four popular organizations, namely Vodafone, EDP (Energias de Portugal), MEO (Serviços de Comunicações e Multimédia, S.A), and Polícia Judicíaria – one of the police organizations responsible for criminal investigations in Portugal. The email message generally refers to overdue invoices – the decoy – in order to lure the victim to download the malicious file (a .zip file downloaded from the Internet). These emails are often sent between the end and the beginning of each month. **_Figure 1: Email templates of URSA impersonating Vodafone, EDP and Polícia Judíciaria – Portugal._** ## URSA loader in detail and the rabbit holes At first glance, the file downloaded via the malicious URL sent by criminals on the email scam is a zip file with an **[MSI (Microsoft Installer) inside. By analyzing the MSI file, it’s possible to observe that another file is available](https://www.virustotal.com/gui/file/23892054f9494f0ee6f4aa8749ab3ee6ac13741a0455e189596edfcdf96416b3/details)** **inside, and probably dropped when the MSI is executed. That file called px3q8x.vbs is a VBscript file responsible** for loading and executing the next stages. Interesting to note this file has a low detection rate bypassing, thus, popular antivirus (AV) engines. **Threat name: 554S2000A2S144D1S4111D.zip** **MD5: 2d2f3500836ed60303103bafac6357a3** **Threat name: 554S2000A2S144D1S4111D.msi** **MD5: 3be539aa8d421d09cef27723a98d2d83** **Threat name: px3q8x.vbs (initial payload – VBScript)** **MD5: a4f066196b1009c42c1dea74f857180d** ----- **_Figure 2: MSI file with another file inside – a VBScript called px3q8x.vbs – the Ursa trojan VBScript loader._** During this article, we can observe that the URSA trojan has two loaders. First, a VBScript loader followed by several rounds of obfuscation and rabbit holes. The final VBScript is responsible for starting and dropping the files on disk and executing an AutoIt loader/injector. That binary injects into the memory via the Process Injection technique some DLLs, including a Delphi binary related to the banking overlay windows, and also the one that establishes all the communication with the C2 server. The following image presents a high-level diagram of how the URSA trojan works. ----- **_Figure 3: URSA trojan / Mispadu 2020 – high-level diagram._** ## VBScript deobfuscation rounds After extracting the **[VBscript loader, we observed that it is very confused and obfuscated as presented in Figure 4.](https://www.virustotal.com/gui/file/d1fb8a5061fc40291cc02cec0f1c2d13168b17d22ffcabea62816e14ed58e925/)** ----- **_Figure 4: URSA VBScript loader – code obfuscated to bypass AV and make hard its analysis._** Some deobfuscation rounds after, we got a more readable version. Notice that some parts related to useless code were removed. In detail, the VBscript is grouped into two parts. The first part is the method of the Installer object that returns a new Record object with the requested number of fields (code highlighted below). **_Figure 5: Analysis of URSA loader VBScript – first part – record object part._** The second part is the code of the next payload encoded. That payload is then executed and is responsible for decoding another payload (the 2nd payload in Figure 5 – step 5). ----- **_Figure 6: Analysis of URSA loader VBScript – second part – payload 2._** This new payload (after deobfuscating the code and renaming some functions and variables) is another VBScript, with the final payload that requests the next stage from the C2 server. Of course, this was funny, some rounds of rabbit holes. ----- **_Figure 7: Analysis of URSA loader VBScript – third part – payload 3 – step 8._** ----- **_Figure 8: Network traffic when the next malware stage is downloaded from C2._** Finally and highlighted above, we got the C2 IP address (191.235.99.]13) and the final payload this stage from the C2 server. ## URSA trojan – VBscript loader/dropper (the final VBScript) **Threat name: final payload (VBScript)** **MD5: bda287c97d9373052f347ac0ccedfdf8** After some rabbit holes, finally, we got the URSA VBScript loader totally deobfuscated from the C2 server. Just the malware configuration is encrypted, and all the communications between the C2 server and trojan clients are performed using the same algorithm, even during the final stage of this malware – a Delphi PE file responsible to create the banking overlay windows, collect credentials from the victim’s machine, and send all the date to the C2 online. ----- **_Figure 9: URSA final VBScript loader and its configuration._** From Figure 9, we can observe the following: some paths from the C2 server (SRoleX and sRoleXW2) the path where binary files from C2 are downloaded to (cRaiz1); and some sections that are used to build the final stage (an AutoIT binary responsible for injecting and executing the malware final stage into the memory – the mentioned Delphi file). As mentioned, all the communications from this point are encrypted between the malware and the C2 server. In [order to decrypt the malware communication, we can use the next script available on GitHub.](https://github.com/sirpedrotavares/SI-LAB-malware/blob/master/decryption%20strings%20ursa%20trojan) By executing the script, decrypt the malware config was possible as observed below. ----- **_Figure 10: Ursa trojan config decrypted._** The variables “#wp#” are the final C2 endpoint where the victim’s information is sent during the malware execution. Also, several host repetitions were identified. This is a potential C2, that notifies criminals when a new victim is affected. Nonetheless, the malware next stage is downloaded from the IP address (191.235.99.]13) as analyzed above. During the VBScript code analysis, some functions were identified: ----- ``` p y ( p,, p y ) function crypt(cText, cCod) function decrypt(cText, cCod) Function UnZip(ZipFile, ExtractTo) Function StringGetURL(sUrl) Function BinaryGetURL(strURL) Function StringGetURL(strURL) Function SaveBinaryData(arrByteArray, strFileName) Sub writeBinary(bstr, path) Function makeArray(n) ' Small utility function Function TrocaEntry(strFileName1, strFileName, sSenhaVelha, sSenhaNova) function cr1pt(x, c) ``` In general, the next malware stage is retrieved from the C2 server in several parts and then built on the fly. The files are encrypted and are decrypted during the malware execution. Next, a final PE file is built during this process. Some interesting functions are presented below. Interesting to note that the user agent used to download the files is: “strUserAgentString = “binary_getter/1.0”“. **_Figure 11: Some parts and functions of the VBScript file._** After this initial process, some validations regarding the victim device are performed to start the next stage. The Operating System (OS) version is retrieved, and if it is a virtual environment, the script terminates its execution. Interesting to observe this anti-VM technique earlier on the trojan loader. With this logic in place, the final payload is not loaded and downloaded from the C2 allowing it not to be at least flagged by antivirus engines. ----- **_Figure 12: Anti-VM technique found on the URSA loader._** Next, the script validates the victim devices is geo-located in target locations defined by the malware operators, namely: **Spanish – Spain (Traditional) 1034** **Portuguese – Brazil – 1046** **Spanish – Mexico – 2058** ----- **Portuguese Portugal 2070** **Spanish – 58378, 3082** **_Figure 13: Target locations affected by URSA malware._** If the victim’s computer is executing in a language ID different from the hardcoded, or the computer name is equal to **“JOHN-PC“, the infection process stops. Change the computer name to “JOHN-PC” is a potential killswitch to** **avoid URSA infections.** At this moment, the next stage is downloaded from the C2 server. The files are stored into the C:\Users\Public folder (tmp file), and next moved to a random folder created on the C:\ drive. The name of this folder is based on the computer name. ----- **_Figure 14: Next binaries (AutoIT the injector/loader) and the URSA trojan (a Delphi binary injected into memory_** _are download from the C2 server._ Along the way, two additional DLLs are also downloaded. One is a DLL for SSL and the other for SQLite3. They are probably dependencies packaged in the malware, and to avoid a failure if the target machine does not have these DLLs/resources installed on the device. We will observe that the final binary – URSA Delphi – has two tools inside and packed. These tools are legitimate software used during the credential harvesting process. After this complex process, the final files are moved into the C:\”artibrary_name” folder. **_Figure 15: Final stage is moved into a random folder created on the C:\ (o0t – in this case)._** ----- Next, another loader/injector, the AutoIT file is executed. It is responsible for loading into the memory the final payload (Delphi file that contains the trojan code and the malicious process). **_Figure 16: Final payload is executed._** ## Ursa trojan – AutoIT loader/injector **Threat name: n11ai.exe** **MD5: c56b5f0201a3b3de53e561fe76912bfd** **Threat name: n111.11n** **MD5: 7396051fd6575180166d66ddf0a9295b** **Threat name: winx86.dll** **MD5: 87f9e5a6318ac1ec5ee05aa94a919d7a** **Threat name: libeay32.dll** **MD5: f3e6c0d52bab27289db2a70e4aab628c** **Threat name: n11** **MD5: 71fdf07084a741b553b97b0d0815fa0e** [The AutoIT binary is protected and can be decompiled with the following script available on GitHub. That script is a](https://github.com/dzzie/myaut_contrib) build of myAut2Exe modified from the original and based on the version 2.12. ----- **_Figure 17: AutoIT decompiled code (n11ai.exe)._** As observed, some calls from kernel32.dll are imported in order to perform the Process Injection technique. ``` LOCAL $KERNELHANDLE=DLLCALL($_MDKERNEL32DLL,"ptr","LoadLibrary","str","kernel32.dll") $_MFHOOKBAK=DLLSTRUCTCREATE("ubyte[7]") DLLCALL($_MDKERNEL32DLL,"int","WriteProcessMemory","ptr",-1,"ptr",DLLSTRUCTGETPTR($_MFHOOKBAK),"ptr",$_MFHOO DLLCALL($_MDKERNEL32DLL,"int","WriteProcessMemory","ptr",-1,"ptr",$_MFHOOKPTR,"byte*",184,"uint",1,"uint*", DLLCALL($_MDKERNEL32DLL,"int","WriteProcessMemory","ptr",-1,"ptr",$_MFHOOKPTR+5,"ushort*",57599,"uint",2,"u ``` In detail, the file n111.11n is one of the DLLs imported – the Delphi PE file. All the DLL files are injected depending on the passed arguments. These command lines are executed in Figure 17, at the end of the VBScript loader. ``` "C:\o0t\n11ai.exe" n11 @ "C:\o0t\n11ai.exe.exe" n11 ##1 "C:\o0t\n11ai.exe.exe" /stext "WWy1" "C:\o0t\n11ai.exe.exe" n11 ##3 "C:\o0t\n11ai.exe.exe" /stext "WWy0" ``` In detail, this AutoIT loader is seen as a maestro. It loads the malware by parts, namely: **n11 @ – DLL inside AutoIT that loads the Delphi binary into the memory.** **n11 /stext “WWy1” – executes the module of collecting passwords from the browser.** **n11 /stext “WWy0” – executes the module of collecting credentials from popular software (FTP, email, etc.).** ----- **_Figure 18: DLLs injected into the memory (Delphi binary, and other)._** On the other side, the two DLLs seem to be referred to SSL and SQLite3, probably dependencies to execute the tool available inside the Delphi PE file (winx86.dll and libeay32.dll). **_Figure 19: DLLs stored in the same path of AutoIT binary (the Delphi loader)._** ## Digging into the URSA final stage (Delphi trojan) **Threat name: 36f0000.rec.dll (extracted from memory)** **MD5: 309335fe1e4f27029a8ec6087e0de1f4** ----- The last stage is a Delphi binary responsible to execute browser overlay to control and steal the victim s data while they are accessing their home banking portals. The activity and code similarities here observed are much close to [other analyzed and popular trojans operating in Portugal and Latin America, such as Grandoreiro and](https://seguranca-informatica.pt/the-updated-grandoreiro-malware-equipped-with-latenbot-c2-features-in-q2-2020-now-extended-to-portuguese-banks/#.X2DFbWhKguU) **[Lampion](https://seguranca-informatica.pt/new-release-of-lampion-trojan-spreads-in-portugal-with-some-improvements-on-the-vbs-downloader/#.X2DFdGhKguU)** [[1,](https://seguranca-informatica.pt/new-release-of-lampion-trojan-spreads-in-portugal-with-some-improvements-on-the-vbs-downloader/#.X2DFdGhKguU) [2]. According to an](https://seguranca-informatica.pt/trojan-lampion-is-back-after-3-months/#.X2DFdWhKguU) **[ESET analysis, the final payload is Mispadu, an ambitious Latin American banking trojan that](https://www.welivesecurity.com/2019/11/19/mispadu-advertisement-discounted-unhappy-meal/)** extends its attack surface to web browsers. The Delphi binary has also two legitimate tools inside. These tools are used to collect credentials stored on the victim’s device. **_Figure 20: Binary files available inside the Delphi binary._** These tools are executed when the final stage starts, and the data is stored between the tags “F1” and “F2” highlighted below. **_Figure 21: Blocks of code where the credential stealer modules are executed._** In detail, these tools are legitimate and from Nir Sofer. The first one – **[WebBrowserPassView is launched in](https://www.nirsoft.net/utils/web_browser_password.html)** [memory and used to exfiltrate credentials from the popular web browsers. On the other side, Mail PassView is used](https://www.nirsoft.net/utils/mailpv.html) to collect data from several locations. ----- **_Figure 22: Tools embedded inside the trojan file and used to collect data from the infected device._** At the end of the harvesting process, the data is sent to the C2 server. ----- **_Figure 23: Victim’s credentials collected and sent to the C2 server._** The trojan is simultaneously listening and monitoring which windows and websites are accessed by the victim (it get the focus windows on the web-browser). When a target banking portal is accessed, an overlay window is created on the legitimate web browser window depending on the accessed banking portal. In short, the next figure shows some target banks “operated” by URSA trojan criminals. ----- **_Figure 24: Target banking organizations operated by URSA trojan loader criminals._** The complete list can be found below. ----- ``` _ .text:039E67EC 0000001C unicode BANCOUNION_BO .text:039E6814 0000000E unicode BNB_BO .text:039E6830 00000010 unicode BISA_BO .text:039E684C 0000000E unicode BCP_BO

More details and full images available at the end of the article. ----- **_Figure 25: Banking overlay windows from URSA trojan banker._** When the malware detects the victims accessed a target home banking portal, a socket connection is established to the malware operator (C2 server). Criminals control each step, requesting specific data step-by-step in a back-office portal. Some commands hardcoded inside the malware are presented in Figure 26. **_Figure 26: Internal commands of URSA trojan._** ----- ## C2 details and victim s data The victim’s data is sent to C2 during the malware execution. During our analysis, it was possible to collect information on the number of victims affected during this wave (June – mid-September), as well as all data exfiltrated from the victims’ devices. **_Figure 27: Some affected users and AV engine installed and running in the infected device._** Interesting that this malware evades AV detection, at least the phase where credentials were collected. We can see in Figure 28 that many affected computers were running popular antivirus and were infected by this threat. On the other side, all the victim’s data is stored in TXT files on the C2 server. The file starts with the id language (Portugal – 2070), followed by the computer name, trojan compilation ID, and finally, the victim ID present on the C2 database. ----- **_Figure 28: Ursa trojan – victim’s details._** The geo-map initially addressed in this article was based on the C2s available below, and based on the number of available infections found there. ## URSA trojan – Banking Overlay Windows ----- ----- ----- ----- ----- ----- ## Mitre Att&ck Matrix Indicators of Compromise (IOCs) ----- ``` g g _ hxxps://medeiros-boatworks.]com/wp-content/!/https:/my.vodafone.pt/?client=xxx hxxps://publichealth.msu.ac.]th/eng/wp-content/languages/--/my.vodafone.pt/?client=xxx hxxps://kresna.co.]id/sarikresnakimia/wp-content/!/www.edp.pt/?client=xxx hxxps://robyn-plombier-chauffagiste.fr/wp-admin/css/--/https:/www.policiajudiciaria.pt/?cliente=xxxx ---- URLS ----hxxp://191.235.99.]13/lp1a.php hxxp://191.235.99.]13/m/ ---- C2 ----191.235.99.]13 191.239.122.]4 40.70.86.]161 52.91.227.]152 87.98.137.]173 144.217.32.]24 51.81.104.]17 104.44.143.]28 51.143.39.]80 45.132.242.]89 13.58.123.]122 51.222.39.]127 66.70.237.]175 54.233.78.]131 51.222.39.]128 54.39.33.]188 -- 21/10/2020-104.41.57.]9 142.44.218.]78 191.235.78.]73 -- 02-11-2020-70.37.106.]179 -- 14-11-2020-40.65.223.]174 40.84.210.]148 -- 01-12-2020-149.56.76.]254 --20-12-2020-24.152.36.]236 193.239.86.]182 47.254.94.]1 ## Online Sandbox URLs ``` **554S2000A2S144D1S4111D.msi:** https://www.virustotal.com/gui/file/23892054f9494f0ee6f4aa8749ab3ee6ac13741a0455e189596edfcdf96416b3/details **px3q8x.vbs initial VBScript:** https://www.virustotal.com/gui/file/d1fb8a5061fc40291cc02cec0f1c2d13168b17d22ffcabea62816e14ed58e925/ **final payload (VBScript):** https://www.virustotal.com/gui/file/5b91c8acffe1980653718a493e24bde7211ee825ea2947df54c03e9733d61a70/details **n11ai.exe (AutoIt loader/injector):** https://www.virustotal.com/gui/file/237d1bca6e056df5bb16a1216a434634109478f882d3b1d58344c801d184f95d/details **6f0000.dll (Delphi trojan):** https://www.virustotal.com/gui/file/93488eab403fafb3d8e10d38c80f0af745e3fa4cf26228acff24d35a149f6269/detection ----- **Samples MalwareBazaar: https://bazaar.abuse.ch/browse/tag/URSA%20trojan/** [[2020-09-13] new #trojan](https://twitter.com/hashtag/trojan?src=hash&ref_src=twsrc%5Etfw) [#banker in the wild –](https://twitter.com/hashtag/banker?src=hash&ref_src=twsrc%5Etfw) [#stealer](https://twitter.com/hashtag/stealer?src=hash&ref_src=twsrc%5Etfw) [#malware](https://twitter.com/hashtag/malware?src=hash&ref_src=twsrc%5Etfw) [#c2](https://twitter.com/hashtag/c2?src=hash&ref_src=twsrc%5Etfw) [➡target countries: #PT�,](https://twitter.com/hashtag/PT?src=hash&ref_src=twsrc%5Etfw) [#BO`,](https://twitter.com/hashtag/BO?src=hash&ref_src=twsrc%5Etfw) [#CHo](https://twitter.com/hashtag/CH?src=hash&ref_src=twsrc%5Etfw) [#ES󾓫,](https://twitter.com/hashtag/ES?src=hash&ref_src=twsrc%5Etfw) [#MX�,](https://twitter.com/hashtag/MX?src=hash&ref_src=twsrc%5Etfw) [#BRa,](https://twitter.com/hashtag/BR?src=hash&ref_src=twsrc%5Etfw) [#IT󾓩](https://twitter.com/hashtag/IT?src=hash&ref_src=twsrc%5Etfw) ➡antivirus bypass🐞 ➡password stealer🐞 ➡browser overlay (banking)🏦 ➡C2 [ 191.235.99.13, 52.91.227.152] @ azure & aws✅ ➡origin: BR a [pic.twitter.com/GW3XtXB8BD](https://t.co/GW3XtXB8BD) [— Pedro Tavares (@sirpedrotavares) September 13, 2020](https://twitter.com/sirpedrotavares/status/1305076741107519488?ref_src=twsrc%5Etfw) [Pedro Tavares](https://seguranca-informatica.pt/author/pipocaz/) **[Pedro Tavares is a professional in the field of information security working as an Ethical Hacker/Pentester, Malware](https://www.linkedin.com/in/sirpedrotavares/)** Researcher and also a Security Evangelist.
