Jaime Blasco, Director of AlienVault Labs, has discovered that Microsoft’s Internet Explorer browser is being exploited by hackers and cyber criminals to expose existing vulnerabilities and security flaws in user’s computers.
Through these vulnerabilities, hackers are gaining access to confidential data. “They collect information through Internet Explorer on the software running on the machine to determine which software can be attacked in the future,” Jaime Blasco explained. “The hackers also share details of web server and computer vulnerabilities with others inside the community.”
Hackers exploit these flaws by searching computers for the type of security software that is being used, which can then help them learn how exactly to take control of them.
“By knowing what security software is installed, the hackers can determine if their attack is going to work. That way they will only attack a computer they know is vulnerable and avoid alerting security companies to their presence,” said Blasco.
This exploitation is occurring over a vast scale; without their knowledge, entire companies, web servers, and users are being targeted via holes within Internet Explorer.
However, it’s not only security software that hackers can gain access to; other software and applications are also vulnerable to exposure and are being used to gain control over a user’s PC. Its solid integration into the Windows software is the main reason that Internet Explorer can be exploited in such a way. Other browsers such as Chrome or Firefox do not have the same degree of integration, and so the exposure is significantly less. Based on this, AlienVault advised that users consider using a third-party browser such as Chrome.
“Chrome is designed with security in mind,” explained Blasco. “It has a suite of security features in place that means that even if attackers find a hole in one layer, they have to bypass other security measures that are in place.”
Microsoft claims it is investigating other issues within the IE browser and is suggesting that users upgrade to the latest IE 11 browser to minimise the risk of exposure. The company has been aware of the existing vulnerabilities for over a year, yet only a few of them have actually been patched.
