"description":"A WEBC2 backdoor is designed to retrieve a Web page from a pre-determined C2 server. It expects the Web page to contain special HTML tags; the backdoor will attempt to interpret the data between the tags as commands. Members of this family of backdoor malware talk to specific Web-based Command & Control (C2) servers. The backdoor has a limited command set, depending on version. It is primarily a downloader, but it classified as a backdoor because it can accept a limited command set, including changing local directories, downloading and executing additional files, sleeping, and connecting to a specific IP & port not initially included in the instruction set for the malware. Each version of the malware has at least one hardcoded URL to which it connects to receive its initial commands. This family of malware installs itself as a service, with the malware either being the executable run by the service, or the service DLL loaded by a legitimate service. The same core code is seen recompiled on different dates or with different names, but the same functionality. Key signatures include a specific set of functions (some of which can be used with the OS-provided rundll32.exe tool to install the malware as a service), and hardcoded strings used in communication with C2 servers to issue commands to the implant.",

"description":"Kazuar is a fully featured backdoor written using the .NET Framework and obfuscated using the open source packer called ConfuserEx. Unit 42 researchers have uncovered a backdoor Trojan used in an espionage campaign. The developers refer to this tool by the name Kazuar, which is a Trojan written using the Microsoft .NET Framework that offers actors complete access to compromised systems targeted by its operator. Kazuar includes a highly functional command set, which includes the ability to remotely load additional plugins to increase the Trojan’s capabilities. During our analysis of this malware we uncovered interesting code paths and other artifacts that may indicate a Mac or Unix variant of this same tool also exists. Also, we discovered a unique feature within Kazuar: it exposes its capabilities through an Application Programming Interface (API) to a built-in webserver. We suspect the Kazuar tool may be linked to the Turla threat actor group (also known as Uroburos and Snake), who have been reported to have compromised embassies, defense contractors, educational institutions, and research organizations across the globe. A hallmark of Turla operations is iterations of their tools and code lineage in Kazuar can be traced back to at least 2005. If the hypothesis is correct and the Turla threat group is using Kazuar, we believe they may be using it as a replacement for Carbon and its derivatives. Of the myriad of tools observed in use by Turla Carbon and its variants were typically deployed as a second stage backdoor within targeted environments and we believe Kazuar may now hold a similar role for Turla operations.",

During this time it has managed to avoid scrutiny by the security community. The current version of the malware allows the operator to steal files, keystrokes, perform screenshots, and execute arbitrary code on the infected host. Talos has named this malware KONNI. \nThroughout the multiple campaigns observed over the last 3 years, the actor has used an email attachment as the initial infection vector. They then use additional social engineering to prompt the target to open a .scr file, display a decoy document to the users, and finally execute the malware on the victim's machine. The malware infrastructure of the analysed samples was hosted by a free web hosting provider: 000webhost. The malware has evolved over time. In this article, we will analyse this evolution:",

The malware in question has ties to a previously reported malware family named KONNI, however, after careful consideration, we believe enough differences are present to introduce a different malware family name. To reflect the close relationship with KONNI, we chose NOKKI, swapping KONNI’s Ns and Ks. Because of code overlap found within both malware families, as well as infrastructure overlap, we believe the threat actors responsible for KONNI are very likely also responsible for NOKKI. Previous reports stated it was likely KONNI had been in use for over three years in multiple campaigns with a heavy interest in the Korean peninsula and surrounding areas. As of this writing, it is not certain if the KONNI or NOKKI operators are related to known adversary groups operating in the regions of interest, although there is evidence of a tenuous relationship with a group known as Reaper.",

"description":"While investigating a recent security incident, Unit 42 found a webshell that we believe was used by the threat actor to remotely access the network of a targeted Middle Eastern organization. The construction of the webshell was interesting by itself, as it was actually two separate webshells: an initial webshell that was responsible for saving and loading the second fully functional webshell. It is this second webshell that enabled the threat actor to run a variety of commands on the compromised server. Due to these two layers, we use the name TwoFace to track this webshell.\nDuring our analysis, we extracted the commands executed by the TwoFace webshell from the server logs on the compromised server. Our analysis shows that the commands issued by the threat actor date back to June 2016; this suggests that the actor had access to this shell for almost an entire year. The commands issued show the actor was interested in gathering credentials from the compromised server using the Mimikatz tool. We also saw the attacker using the TwoFace webshell to move laterally through the network by copying itself and other webshells to other servers.",

"description":"The Winter Olympics this year is being held in Pyeongchang, South Korea. The Guardian, a UK Newspaper reported an article that suggested the Olympic computer systems suffered technical issues during the opening ceremony. Officials at the games confirmed some technical issues to non-critical systems and they completed recovery within around 12 hours. Sunday 11th February the Olympic games officials confirmed a cyber attack occurred but did not comment or speculate further.\nTalos have identified the samples, with moderate confidence, used in this attack. The infection vector is currently unknown as we continue to investigate. The samples identified, however, are not from adversaries looking for information from the games but instead they are aimed to disrupt the games. The samples analysed appear to perform only destructive functionality. There does not appear to be any exfiltration of data. Analysis shows that actors are again favouring legitimate pieces of software as PsExec functionality is identified within the sample. The destructive nature of this malware aims to render the machine unusable by deleting shadow copies, event logs and trying to use PsExec & WMI to further move through the environment. This is something we have witnessed previously with BadRabbit and Nyetya.",
"description":"The malware in question is configured with the following three exported functions: ServiceMain,Rundll32Call, DllEntryPoint. The ServiceMain exported function indicates that this DLL is expected to be loaded as a service. If this function is successfully loaded, it will ultimately spawn a new instance of itself with the Rundll32Call export via a call to rundll32.exe. The Rundll32Call exported function begins by creating a named event named ‘RunOnce’. This event ensures that only a single instance of DDKong is executed at a given time. If this is the only instance of DDKong running at the time, the malware continues. If it’s not, it dies. This ensures that only a single instance of DDKong is executed at a given time. DDKong attempts to decode an embedded configuration using a single byte XOR key of 0xC3. After this configuration is decoded and parsed, DDKONG proceeds to send a beacon to the configured remote server via a raw TCP connection. The packet has a header of length 32 and an optional payload. In the beacon, no payload is provided, and as such, the length of this packet is set to zero. After it sends the beacon, the malware expects a response command of either 0x4 or 0x6. Both responses instruct the malware to download and load a remote plugin. In the event 0x4 is specified, the malware is instructed to load the exported ‘InitAction’ function. If 0x6 is specified, the malware is instructed to load the exported ‘KernelDllCmdAction’ function. Prior to downloading the plugin, the malware downloads a buffer that is concatenated with the embedded configuration and ultimately provided to the plugin at runtime. As we can see in the above text, two full file paths are included in this buffer, providing us with insight into the original malware family’s name, as well as the author. After this buffer is collected, the malware downloads the plugin and loads the appropriate function. This plugin provides the attacker with the ability to both list files and download/upload files on the victim machine.",
"description":"This sample is configured with three exported functions: Add, Sub, DllEntryPoint. The DLL expects the export named ‘Add’ to be used when initially loaded. When this function is executed PLAINTEE executes a command in a new process to add persistence. Next, the malware calls the ‘Sub’ function which begins by spawning a mutex named ‘microsoftfuckedupb’ to ensure only a single instance is running at a given time. In addition, PLAINTEE will create a unique GUID via a call to CoCreateGuid() to be used as an identifier for the victim. The malware then proceeds to collect general system enumeration data about the infected machine and enters a loop where it will decode an embedded config blob and send an initial beacon to the C2 server. The configuration blob is encoded using a simple single-byte XOR scheme. The first byte of the string is used as the XOR key to in turn decode the remainder of the data. The malware then proceeds to beacon to the configured port via a custom UDP protocol. The network traffic is encoded in a similar fashion, with a random byte being selected as the first byte, which is then used to decode the remainder of the packet via XOR. This beacon is continuously sent out until a valid response is obtained from the C2 server (there is no sleep timer set). After the initial beacon, there is a two second delay in between all other requests made. This response is expected to have a return command of 0x66660002 and to contain the same GUID that was sent to the C2 server. Once this response is received, the malware spawns several new threads, with different Command parameters, with the overall objective of loading and executing a new plugin that is to be received from the C2 server. During a file analysis of PLAINTEE in WildFire, we observed the attackers download and execute a plugin during the runtime for that sample. PLAINTEE expects the downloaded plugin to be a DLL with an export function of either ‘shell’ or ‘file’. The plugin uses the same network protocol as PLAINTEE and so we were able to trivially decode further commands that were sent. The following commands were observed: tasklist, ipconfig /all. The attacker performed these two commands 33 seconds apart. As automated commands are typically performed more quickly this indicates that they may have been sent manually by the attacker.",

"description":"In early May, Unit 42 discovered an attack campaign against at least one defense company in Russia and one unidentified organization in South Korea delivering a variant of Bisonal malware. While not previously publicly documented, the variant has been in the wild since at least 2014. There are three primary differences between it and older Bisonal malware including a different cipher and encryption for C2 communication, and a large rewrite of the code for both network communication and maintaining persistence. To date, we have only collected 14 samples of this variant, indicating it may be sparingly used. The adversary behind these attacks lured the targets into launching the Microsoft Windows executable malware by masquerading it as a PDF file (using a fake PDF icon) and reusing publicly available data for the decoy PDF file’s contents. Attacks using Bisonal have been blogged about in the past. In 2013, both COSEINC and FireEye revealed attacks using Bisonal against Japanese organizations . In October 2017, AhnLab published a report called “Operation Bitter Biscuit,” an attack campaign against South Korea, Japan, India and Russia using Bisonal and its successors, Bioazih and Dexbia. ",

It is strongly suspected that Agent ORM has been deprecated in favor of script-based first-stage implants (VB Flash, JS Flash, and Bateleur).",
"description":"VB Flash was first observed being deployed alongside Agent ORM in September 2015. It is likely that this was developed as a replacement to Agent ORM and contained similar capabilities. The first observed instance of VB Flash included comments and was easy to analyze—later versions soon began to integrate multiple layers of obfuscation. Several versions of VB Flash were developed including ones that utilized Google Forms, Google Macros, and Google Spreadsheets together to make a command-and-control (C2) channel. This variant would POST victim data to a specified Google form, then make a request to a Google macro script, receiving an address for a Google Spreadsheet from which to request commands.",
"description":"JS Flash capabilities closely resemble those of VB Flash and leverage interesting techniques in deployment via batch scripts embedded as OLE objects in malicious documents. Many iterations of JS Flash were observed being tested before deployment, containing minor changes to obfuscation and more complex additions, such as the ability to download TinyMet (a cutdown of the Metasploit Meterpreter payload). PowerShell was also used heavily for the execution of commands and arbitrary script execution. No JS Flash samples were observed being deployed after November 2017.",
"description":"Bateleur deployments began not long after JS Flash and were also written in JavaScript. Deployments were more infrequent and testing was not observed. It is likely that Bateleur was run in parallel as an alternative tool and eventually replaced JS Flash as CARBON SPIDER’s first stage tool of choice. Although much simpler in design than JS Flash, all executing out of a single script with more basic obfuscation, Bateleur has a wealth of capabilities—including the ability to download arbitrary scripts and executables, deploy TinyMet, execute commands via PowerShell, deploy a credential stealer, and collect victim system information such as screenshots.",

Maybe the author named every variant withthe name of each brother. After some searches using Google, we identified anold variant of this malware here: http://contagiodump.blogspot.ca/2010/10/oct-08-cve-2010-2883-pdf-nuclear.html. The code of the malware available on the blog is closeto our case but with fewer features. In 2010, the password of the Gmail account was futurekimkim. Three years ago, the author was already fixatedon the Kim family...The language of the resource stored in the .dll file is Korean (LANG_KOREAN). The owner of the gmail mailbox is laoshi135.zhangand the secret question of this account is in Korean too.We don’t know if the malware truly comesfrom Korea.However, thanks to these factors, we decided to name this sample KimJongRAT/Stealer.",
"description":"Based on our research, it appears the malware author calls the encoded secondary payload “Cowboy” regardless of what malware family is delivered.",
"description":"JasperLoader employs a multi-stage infection process that features several obfuscation techniques that make analysis more difficult. It appears that this loader was designed with resiliency and flexibility in mind, as evidenced in later stages of the infection process. ",
"description":"The malware Scranos infects with rootkit capabilities, burying deep into vulnerable Windows computers to gain persistent access — even after the computer restarts. Scranos only emerged in recent months, according to Bitdefender with new research out Tuesday, but the number of its infections has rocketed in the months since it was first identified in November.",
"description":"Unit 42 has discovered a new malware family we’ve named “Reaver” with ties to attackers who use SunOrcal malware. SunOrcal activity has been documented to at least 2013, and based on metadata surrounding some of the C2s, may have been active as early as 2010. The new family appears to have been in the wild since late 2016 and to date we have only identified 10 unique samples, indicating it may be sparingly used. Reaver is also somewhat unique in the fact that its final payload is in the form of a Control panel item, or CPL file. To date, only 0.006% of all malware seen by Palo Alto Networks employs this technique, indicating that it is in fact fairly rare.",
"description":"The Citizen Lab analyzed a malicious email sent to Tibetan organizations in June 2013. The email in question purported to be from a prominent member of the Tibetan community and repurposed content from a community mailing list. Attached to the email were what appeared to be three Microsoft Word documents (.doc), but which were trojaned with a malware family we call “Surtr”.1 All three attachments drop the exact same malware. We have seen the Surtr malware family used in attacks on Tibetan groups dating back to November 2012.",
"description":"SunOrcal is a trojan malware family whose activity dates back to at least 2013. A version discovered in November 2017 incorporates steganography techniques and can collect C2 information via GitHub, obscuring its C2 infrastructure and evading detection using the legitimate site for its first beacon. The threat actors have targeted users in the Vietnam area, spreading phishing emails containing malicious documents purportedly regarding South China Sea disputes. The new SunOrcal version has also been used with the recently discovered Reaver trojan and the original SunOrcal version. Some of the recent activity also incorporates the use of the Surtr malware.",
"description":"Threat actors have delivered Bookworm as a payload in attacks on targets in Thailand. Readers who are interested in this campaign should start with our first blog that lays out the overall functionality of the malware and introduces its many components.\n Unit 42 does not have detailed targeting information for all known Bookworm samples, but we are aware of attempted attacks on at least two branches of government in Thailand. We speculate that other attacks delivering Bookworm were also targeting organizations in Thailand based on the contents of the associated decoys documents, as well as several of the dynamic DNS domain names used to host C2 servers that contain the words “Thai” or “Thailand”. Analysis of compromised systems seen communicating with Bookworm C2 servers also confirms our speculation on targeting with a majority of systems existing within Thailand.",
"description":"We named the malware family described in the rest of this blog post Amavaldo. This family is still in active development – the latest version we have observed (10.7) has a compilation timestamp of June 10th, 2019.",
"description":"hacker going by the handle Mr. Burns. He also created something similar called RMS, which behaves very much like the TVSPY builder.\n“RMS/TVSPY continues to be developed, with a new version being posted by the developer/reseller on a regular basis,” Damballa researchers noted. “In fact, the legitimate RMS version developed by TektonIT and the version posted in criminal forums appear to be identical. TVSPY seems to be merely a modification of RMS to utilize TeamViewer infrastructure and a command-and-control interface manageable through the Web.",
"description":"The COMpfun malware was initially documented by G-DATA in 2014. Although G-DATA didn’t identify which actor was using this malware, Kaspersky tentatively linked it to the Turla APT, based on the victimology. Our telemetry indicates that the current campaign using Reductor started at the end of April 2019 and remained active at the time of writing (August 2019). We identified targets in Russia and Belarus.",
"description":"We called these new modules ‘Reductor’ after a .pdb path left in some samples. Besides typical RAT functions such as uploading, downloading and executing files, Reductor’s authors put a lot of effort into manipulating digital certificates and marking outbound TLS traffic with unique host-related identifiers. The Kaspersky Attribution Engine shows strong code similarities between this family and the COMPfun Trojan. Moreover, further research showed that the original COMpfun Trojan most probably is used as a downloader in one of the distribution schemes. Based on these similarities, we’re quite sure the new malware was developed by the COMPfun authors.",

"description":"DePriMon is a malicious downloader, with several stages and using many non-traditional techniques. To achieve persistence, the malware registers a new local port monitor – a trick falling under the “Port Monitors” technique in the MITRE ATT&CK knowledgebase. For that, the malware uses the “Windows Default Print Monitor” name; that’s why we have named it DePriMon. Due to its complexity and modular architecture, we consider it to be a framework.",
