HIJACKING IN COMPUTER SECURITY CODE

Note: While man-in-the-middle attacks are usually considered to be a network security issue, SSL hijacking most often affects websites and web applications (because they use the HTTPS protocol), so it could be considered a web application security issue. SSL hijacking is considered a man-in-the-middle attack (MITM) technique. As a result, the victim assumes they have a secure connection to the target site, but in reality, they have a secure connection to a cloned or proxy site controlled by the attacker. “You cannot really expect to provide all of the business users in an enterprise capabilities that were, up until a few months ago, reserved only to developers and expect everything to go well.SSL hijacking is a type of attack where the attacker generates fake certificates for the domains of HTTPS sites the victim attempts to visit. “It’s very important to monitor what RPA agents are doing,” he says. “In an uncommon move, the attacker used the customer’s existing systems, including eDiscovery, the Compliance Search feature, and Microsoft Flow, to automate stealing its search results,” Microsoft wrote in an incident report.Īs the possible risks around low-code/no-code applications become more obvious, Bargury says companies may need to reassess their policies. One of the hacker groups used automated systems to remove data. In early 2020, Microsoft’s security team found six hacker groups, including a Chinese APT, inside the network of one company. While the popularity of RPA tools is increasing, there have already been real-world attacks designed to abuse the platforms. However, to be successful, Bargury says, the move relies upon security teams having consistent and clear policies across their organizations, which isn’t always the case. This process would put controls on the account types that can sign in to Power Automate, thus reducing the potential for the system to be abused. He published demos and the steps needed to conduct the attack to help raise awareness of the potential issues companies face.īefore his DefCon talk, Microsoft’s team reached out to him, Bargury says, and pointed out that business network admins can restrict access to Power Automate tools by “ adding a registry entry” to their devices.

“When you think about the architecture, this is a remote code execution tool that is built by Microsoft and signed by Microsoft all throughout the way,” Bargury says. This type of attack could be hard to detect, as it uses official systems and processes throughout, Bargury says. “This technique relies on a hypothetical scenario where a system is already compromised or susceptible to a compromise using existing techniques like social engineering-both for the initial and any subsequent network attack,” the spokesperson adds, recommending that people keep their systems up to date. “There is no mechanism by which a fully updated machine with antivirus protections can be remotely compromised using this technique,” the spokesperson says. “You can exfiltrate data outside of the corporate networks through this trusted tunnel, you can build keyloggers, you can take information from the clipboard, you can control the browser,” Bargury says.Ī spokesperson for Microsoft downplayed the potential of the attack, pointing out that an account would need to have been accessed by an attacker before it could be used. Other demos show how an attacker can steal authentication tokens from a machine. Ahead of his DefCon talk, he created multiple demos showing how it is possible to use Power Automate to push out ransomware to impacted machines. “Once you do that, you will get a URL that would allow you, as an attacker, to send payloads to the machine,” Bargury says.
