Unveiling the Latest Cyber Threat ‘Indirector’: Safeguarding Sensitive Data

The New Side-Channel Attack on Intel CPUs: Indirector

In the realm of IT security, Intel’s latest CPUs, such as Raptor Lake and Alder Lake, have fallen prey to a novel side-channel attack. This newly discovered vulnerability, named Indirector by the vigilant security experts Luyi Li, Hosein Yavarzadeh, and Dean Tullsen, capitalizes on the weaknesses found in the Indirect Branch Predictor (IBP) and the Branch Target Buffer (BTB). These components, integral to the CPU’s functioning, can be exploited to illicitly divulge confidential information residing within the processor.

The Intricacies of the Attack

The Indirector attack method intricately exploits the flaws in the IBP and BTB, components vital for predicting the direction of program execution within the CPU. By manipulating these elements, the assailants can clandestinely extract sensitive data, circumventing conventional security barriers.

Implications for Intel CPU Users

For users of Intel’s Raptor Lake and Alder Lake processors, the emergence of this vulnerability poses a significant threat to the security of their data. The exploitation of the Indirector attack could lead to the unauthorized disclosure of private information, making it imperative for users to stay informed and vigilant.
