Do you know what Sednit is?
The term Sednit refers to a family of malware infections which function as backdoors and information stealers. The latest Sednit-related malware attack is known to have targeted government, military, and media from around the world. Attackers created several phishing emails concerning important events around the world and sent them to individuals who were believed to be interested in the events. Further information related to the issues described in the email was provided in the email attachment, and, once the user opened the document, the Sednit malware was executed. Additionally, the latest Sednit malware is known to be spread by injecting malicious iframes, which redirect the victim to certain exploits, into legitimate websites.
For example, malware researchers have observed that some redirections to the exploit kit are made from websites owned by a large financial institution based in Poland. The research has shown that the exploit kit is loaded through an iframe added near the end of the HTM document.
Moreover, it has been found that the Sednit malware is related to 3 different exploits used to affect the Internet Explorer browser, including the vulnerabilities CVE-2013-1347, CVE-2013-3897, and CVE-2014-1776, which are aimed at affecting Internet Explorer 8 (MS13-038), Internet Explorer 8 (MS13-080), and Internet Explorer 11 (MS14-021), respectively.
After installation, the Sednit malware receives commands from remote attackers and surreptitiously gathers and transmits data. This malware program is the major component of the targeted attack, because it provides means to steal valuable information from compromised systems. This attack operation is considered sophisticated since the attackers have chosen to compromise the computers of authoritative institutions. Instances like the one with the Sednit malware should encourage the administrators of systems using web-based mail to take the issue into account and adapt new protection strategies.
