Apache Log4j2 Vulnerability Attack Trend from the Perspective of Honeypot

2021-12-21 12:47

Our team spent great deal of effort on simulating different protocols, applications and vulnerabilities with our honeypot (Anglerfish and Apacket) system. When big event happens, we are always curious what we see from the honeypot side. Since log4j came to light 10 days ago, we have published two related blogs, here and here. And looks like more malware are jumping on the bandwagon, as of December 17, we have captured a total of 72,242 attacks launched by 2042 attack source IPs (250 in China and 1,792 abroad), with the source IPs involved in 54 countries, and 132 attack source IPs were found to have exploited the vulnerability to propagate 617 known malware md5s belonging to 30 malware families.

The graph above shows the curve of the number of exploit attacks over time, which shows that the number of attack sessions rose rapidly in the next few days after the vulnerability was exposed. On December 18, the day with the highest number of attack sessions so fare, there were over 28,000 attack sessions in one day. starting on December 13, there were also combined attacks of this vulnerability with other vulnerabilities (Apache Flink, Hadoop, Apache Struts2 vulnerability, etc.).

The figure above shows the main attack source IPs, so far the No.1 is 78.31.71.248(PDNS points to srv62134.dus4.dedicated.server-hosting.expert), accounting for about 9% of the overall IP attacks, and the other main attack source IPs are shown in the legend on the right.

In terms of spreading malware, we reported the first botnet(Muhstik) taking advantage of this at exactly 8:00 on December 11, the number of malware spreading increasing significantly over time after that.

IPs sessions with malware md5s malware families
170.210.45.163 4,753 28 6
167.71.175.10 4,678 15 4
164.52.53.163 3,926 30 6
46.105.95.220 3,710 30 6
1.116.59.211 2,824 31 6
89.249.63.3 2,195 31 6
86.109.208.194 2,121 29 6
178.176.202.121 2,081 29 6
175.6.210.66 2,025 30 7
191.232.38.25 1,776 23 6

The table above lists the 10 IPs that spread the most malware, as well as the number of malware md5s and the number of malware families spread by each IPs.

When we break down the 1083 executable samples and Java bytecode, we get a total of 107 groups of samples, which are mainly Java bytecode files, according to ssdeep values. 30 groups of samples (617 malware md5s) can be identified as specific malware families and the rest of them are currently unknown.

In terms of malware download servers, 34.221.40.237 is the most frequent download server, with nearly half of the malware coming from this download server. This is an AWS cloud server IP located in the U.S. Other common download servers are shown in the legend on the right side of the image above, and the table below lists the 10 download servers used by the attackers.

download servers attackers malware md5s malware families sessions
34.221.40.237 102 8 2 50,358
159.89.182.117 102 1 1 1,850
18.228.7.109 75 15 1 2,947
31.220.58.29 73 6 2 467
137.184.174.180 66 1 1 1,097
68.183.165.105 66 5 1 6,334
210.141.105.67 51 1 1 183
45.130.229.168 15 1 1 34
103.13.230.149 14 6 1 156
54.210.230.186 14 1 1 19
45.80.181.55 6 6 1 54

Among the attack source IPs that can be traced, most of attackers come from Alpha Strike Labs (a German network security company). In addition to security vendors and research institutions, there are also a large number of attacks from Tor exit nodes.
