Recently, moneycontrol.com, a leading financial portal, suffered an iFrame injection attack. Portal information security professionals addressed the vulnerabilities. iFrame tags are used to embed links from other sites on a website. An iFrame injection is a form of cross-site scripting attack where hackers inject iFrame tags into a web page. The tag can download malicious files and infect the web page and related databases. Visitors to the iFrame injected web page are redirected to a fraudulent website with malicious files. Then the user’s browser is loaded with exploits to insert viruses and Trojans on their computer systems.
Flaws in web page development can lead to backdoors or security holes that hackers are waiting to exploit. Financial portals and blogging sites are some of the most common targets of iFrame attacks because they are regularly visited by users and contain large user databases. Such attacks require the use of forensic computer techniques to determine the cause of the attack and gather evidence. Information security professionals usually use ethical hacking to identify and mitigate vulnerabilities.
iFrame attacks can compromise sensitive customer information, change databases and access privileged information. Information security professionals can mitigate iFrame attacks by conducting security audits and identifying and removing unauthorized iFrame tags and codes in the content. They can also identify and remove iFrame tags, which lead to an unknown or suspicious site. When discovering an attack, all passwords related to the website and its databases must be changed immediately. The infected files on the website can be removed and replaced with a new file or a backup of the old content.
Organizations must regularly review the entire IT infrastructure to identify the potential vectors that can help hackers launch attacks and take security measures.
