IIS Servers | Breaking Cybersecurity News | The Hacker News

A China-linked threat actor has been attributed to a cyber attack targeting an U.S. non-profit organization with an aim to establish long-term persistence, as part of broader activity aimed at U.S. entities that are linked to or involved in policy issues. The organization, according to a report from Broadcom's Symantec and Carbon Black teams, is "active in attempting to influence U.S. government policy on international issues." The attackers managed to gain access to the network for several weeks in April 2025. The first sign of activity occurred on April 5, 2025, when mass scanning efforts were detected against a server by leveraging various well-known exploits, including CVE-2022-26134 (Atlassian), CVE-2021-44228 (Apache Log4j), CVE-2017-9805 (Apache Struts), and CVE-2017-17562 (GoAhead Web Server). Symantec and Carbon Black told The Hacker News that there is no indication that these exploitation efforts were successful. It's suspected that the attackers ul...

Threat actors have been observed targeting Internet Information Services (IIS) servers in Asia as part of a search engine optimization (SEO) manipulation campaign designed to install BadIIS malware. "It is likely that the campaign is financially motivated since redirecting users to illegal gambling websites shows that attackers deploy BadIIS for profit," Trend Micro researchers Ted Lee and Lenart Bermejo said in an analysis published last week, Targets of the campaign include IIS servers located in India, Thailand, Vietnam, Philippines, Singapore, Taiwan, South Korea, Japan, and Brazil. These servers are associated with government, universities, technology companies, and telecommunications sectors. Requests to the compromised servers can then be served altered content from attackers, ranging from redirections to gambling sites to connecting to rogue servers that host malware or credential harvesting pages. It's suspected that the activity is the work of a Chinese-s...
