IIS attacks increase from 2,000 to 1.7 million over last quarter

Compromised Servers from China Observed Carrying Out Attacks on eSentire Detection Surface

CAMBRIDGE, ONTARIO – October 9, 2018 – IIS, Drupal, and Oracle WebLogic web technologies experienced increased attacks in Q2 2018. According to the new Q2 2018 Quarterly threat report from eSentire, Inc., the largest pure-play Managed Detection and Response (MDR) provider, IIS attacks showed a 782x increase, from 2,000 to 1.7 million, since last quarter.

Analysis of the attacks by eSentire Threat Intelligence revealed that both IIS and WebLogic exploits maintained a consistent number of attacks (about 200) per IP across organizations, with those attacks originating from servers hosting Apache, RDP, SQL, IIS, and HTTP API services.

Most sources targeting IIS web servers originated from China-based IP addresses. According to Shodan, there are 3.5 million IIS web servers exposed (with 1 million in China). The compromised servers largely originated from Tencent and Alibaba.

eSentire also noted an interesting collection of operating systems among the attacking infrastructure involved – over 400 of the attacking IPs had Shodan records indicating they were Windows machines (including XP, 7, 8, 2008, and 2012). Additionally, nearly 350 FTP servers and over 100 mail servers were reported; there were also VPN servers, MikroTik devices (reported as bandwidth-testing servers), Kangle, Squid, Jetty, and a handful of lesser-known web service technologies.

“IIS is a popular web server, with prevalence in the U.S. and China. Organizations using web servers need to make sure they monitor for these vulnerabilities and update or patch as necessary. Oracle WebLogic is another web server that saw a lot of attacks and we’ve seen Apache attacks reported too,” said Kerry Bailey, CEO, eSentire. “Web servers are exposed de facto, which makes them a primary target, and we saw continued attacks against IIS continue in Q3 2018. IIS patches for earlier versions, like 6.0, are available. Otherwise, users should consider updating to more recent versions of the web server.”

Report Methodology

The eSentire Threat Intelligence team used data gathered from 2,000+ proprietary network and host-based detection sensors distributed globally across multiple industries. Raw data were normalized and aggregated using automated machine-based processing methods. Processed data was reviewed by a visual data analyst applying quantitative analysis methods. Quantitative intelligence analysis results were further processed by a qualitative intelligence analyst resulting in a written analytical product.

eSentire’s 2018 Q2 Threat Report provides a quarterly snapshot, analyzing all cyber threat events investigated by the eSentire Security Operations Center (SOC) while addressing three key areas: threat types, threat volume, and attack types. Each topic is divided into multiple sections, including visual data analysis, written analytical analysis, practical recommendations, and key assumptions.
