The new Bigviktor Botnet is Targeting DrayTek Vigor Router

Overview


On June 17, 2020, 360Netlab Threat Detecting System flagged an interesting ELF sample (dd7c9d99d8f7b9975c29c803abdf1c33), further analysis shows that this is a DDos Bot program that propagates through the CVE-2020-8515 vulnerability which targets the DrayTek Vigor router device, and it uses DGA (Domain generation algorithm) to generate C2 domain names.


The program uses "viktor" as file name ( /tmp/viktor) in the propagation process, also a special string 0xB16B00B5(big boobs) was used in the sample , we combined the two and named it Bigviktor.


From the network’s perspective, Bigviktor’s DGA generates 1000 domain names every month, and traverses the 1000 domain names by requesting RC4 encryption & ECSDA256 signed s.jpeg , When a live C2 responses the request, bot then takes the next step to request for image.jpeg from C2 to get more instructions.


Bigviktor supports 8 kinds of instructions, which can be divided into 2 major functions


• DDoS attack

• Self-renewal


The overall network structure is shown in the figure,






Botnet scale



Daily Active Bot


DGA is a double-edged sword. While giving the author good chance to evade detection, it also gives security researcher the opportunity to register domain names to hijack infected hosts of botnets.

We registered several domains names generated by Bigviktor in June and July (workfrequentsentence.club , waitcornermountain.club), so we were able to tap into it network to measure the scale of the Botnet. As of now we only see about 900 active infected IPs. However, When taking a look at the requests of Bigviktor DGA domain name, we can see the trend is steadily going up. Its daily active Bot trend is shown in the figure below:






Bot geographic location


The IP area distribution of infected devices is as follows:



The main ASN distribution of these IPs is as follows:


412	AS45899|VNPT_Corp
194	AS7552|Viettel_Group
190	AS18403|The_Corporation_for_Financing_&_Promoting_Technology
90	AS3462|Data_Communication_Business_Group
82	AS15525|Servicos_De_Comunicacoes_E_Multimedia_S.A.
66	AS8151|Uninet_S.A._de_C.V.
52	AS45903|CMC_Telecom_Infrastructure_Company
34	AS3352|Telefonica_De_Espana
28	AS17552|True_Internet_Co.,Ltd.
22	AS8881|1&1_Versatel_Deutschland_GmbH




Infected device


By obtaining the title of the infected device's 80, 8080, and 443 port web pages, we know that the currently distributed version of the infected DrayTek Vigor router is:


269 Vigor 2960
107 Vigor 3900
87  Vigor 300B  




Reverse analysis


We have captured a total of 2 versions. The first version of the bot program seems to have bugs and cannot run normally. This article uses the latest version as an example for reverse analysis.


MD5:dd7c9d99d8f7b9975c29c803abdf1c33
ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, stripped
Packer: None



Generally speaking, the Bigviktor function is relatively simple. It binds a local port at runtime to implement a single instance, uses the RC4 algorithm to decrypt sensitive resources, including the strings to be used by DGA, and then uses DGA to generate 1000 C2 domain names based on these strings. Then the bot uses the libcurl library to send a request to the built-in legit websites to test network connectivity. If the network is up, it moves on to next step to request the s.jpeg from the C2 domain to verify the legitimacy of C2; after passing the legality test, it goes to final step to request the male.jpeg and image.jpeg resources from the C2 domain to conduct DDos attack.


We can roughly divide the bot behaviors into two categories: auxiliary behavior and malicious behavior, let us take a close look.



Auxiliary behavior


1: Use libcurl library to access network resources


DNS Option:
    1.1.1.1,8.8.8.8
User-Agent Option:
    Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36"
Accept Option:
    Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8



2: Bind port 61322 to implement a single instance





3: RC4 encrypts sensitive resources, the resources include the stings required by DGA, legit websites, upgrade file storage path, etc.




The RC4 key is


DA B2 F1 F7 32 FD 03 BA 58 DB FF 53 8B F2 6F 01 
02 FF 00 01 03 05 00 DE 02 FF 00 01 7C DF 92 91



Take the suffixes required by DGA to generate domain as an example, the ciphertext is as follows

Visit one of these URLs to get the current date, which will be used in DGA.


format          %a, %d %b %Y
Fri, 10 Jul 2020




Malicious behavior


1: Use the C2 domain name generated by DGA


The format of the domain name is [prefix.]verbe[-]adjective[-]noun.surfix, the content in [] indicates optional, theprefix has 40 words, the verbe has 100 words, the adjective has 525 words, noun has 1522 words, and surfix has 20 words. The algorithm is implemented as follows


 void GenNewKey(uint32_t &key)
 {
 	uint32_t tmp = key ^ (key << 13) ^ ((key ^ (uint32_t)(key << 13)) >> 17);
 	key = tmp ^ 32 * tmp;
 };	
 	string c2url;
 	GenNewKey(seed);
 //1:prefix part
 	if (seed % 5 == 0)
 	{
 		GenNewKey(seed);
 		c2url += prefix[seed % 40];
 		c2url += ".";
 	}
 //2:verbe part
 	GenNewKey(seed);
 	c2url += verbe[seed % 100];
 	GenNewKey(seed);
 	if (seed % 10 <= 1)
 		c2url += "-";
 //3:adj part
 	GenNewKey(seed);
 	c2url += adj[seed % 525];
 	GenNewKey(seed);
 	if (seed % 10 <= 1)
 		c2url += "-";
 //4:noun part
 	GenNewKey(seed);
 	c2url += noun[seed % 1522];
 	c2url += ".";
 //5:surfix part
 	GenNewKey(seed);
 	c2url += surfix[seed % 20];



The current date converts into a string with format%b %Y 00:00 and the initial key is the first 4 bytes of the SHA256 value of the string, for example


currtent date: Fri, 10 Jul 2020
format	---->Jul 2020 00:00
sha256	---->6ac0f83915ed5d7b9bb7055723084df001b16a552d758de3c415f083f931ab8c
get first 4 bytes	----> key=0x6ac0f839




Therefore, the DGA doamin is different every month. Taking the July key (0x6ac0f839) as an example, the first 5 domains generated


c2url: decidefresh-county.in
c2url: payculturaltour.org
c2url: standvisiblereach.rocks
c2url: meanforwardcap.top
c2url: raisefitsize.rocks



When we observe the actual DNS data in packet, we can see the result matches.



See the end of the article for all DGA domains in July.


2: Get the current effective C2


To connect to a vaild C2, Bigviktor start from a random position of the 1000 DGA domains. If there is no valid C2, it goes back to the first domain name and start over again.

In order to ensure that the network is completely controllable and not stolen by others, Bigviktor will verify the signature of the s.jpeg file. Only after passing the signature verification, a C2 is deemed valid.





The real payload encryption is hidden in the jpeg (s.jpeg;image.jpeg)file. The structure of jpeg is IMAGE DATA(16 BYTES): Half-RC4 KEY(16 BYTES): Ciphertext. Each sample integrates a Half-RC4 KEY(16 BYTES),each payload integrates a Half-RC4 KEY(16 BYTES), two Half-RC4 keys are spelled into a complete RC4 key(32 BYTES); also a hard-coded ECDSA256 public key is used to verify the decrypted payload.


  Half-RC4 KEY:
  82 BC 09 D5 47 A9 37 27 8F ED F1 7B 29 2A FA 67
  Pub KEY:
  03 2F 37 51 43 1F A3 58 81 66 86 F7 BA 4C A2 30 
  45 2C 9B 9E 12 9A E9 97 CF 69 09 CF 7F 42 D4 97 88 



Take s.jpeg(md5:4c6d0bed21bc226dbaf4e6adc7402563) as an example




Splice out the complete RC4 key


  Half RC4 KEY from s.jpeg + Half Rc4 from sample
  ------------------------------------------------------
  46 00 B2 65 B0 3F 97 7F CF CB 65 31 1F D2 B3 A0
  82 BC 09 D5 47 A9 37 27 8F ED F1 7B 29 2A FA 67



Decrypt Ciphertext to get



When the verification is successful, a valid C2 is obtained.The procedures of verification need to meet these condition


 * signature verification
 * Plaintext[2] ==\x00,Plaintext[3] ==\x09
 * C2 in the plaintext is same as the Dga domain which responds to the s.jpeg request.


3:Ask for specific tasks from C2


After the Bot obtains a valid C2, it will request the image.jpeg resource from C2



Similarly, image.jpeg also needs to be decrypted and verified. After successful verification, the Bot will perform the corresponding DDos attack or update according to the instructions of image.jpeg.


Bigviktor supports a total of 8 operations,

Take a payload from June,image.jpeg(md5:2e8c223f8ac1f331c36acd32ee949f6f) as an example







Decrypt Ciphertext to get







We can see that bot will launch "connect" ddos attack and the target is 202.162.108.55:80. The result matches the pcap info.
