Apple Silicon Security Risks: How FLOP and SLAP Expose Sensitive Data

Understanding the Latest Threat to Apple Devices

Apple has long been known for its strong focus on security, but recent reports have revealed two significant vulnerabilities in Apple-designed chips that could put millions of users at risk. These flaws, named FLOP and SLAP, exploit speculative execution, a technique used to improve processing efficiency, to leak sensitive data from web browsers like Safari and Chrome.

These vulnerabilities affect Macs, iPhones, and iPads manufactured in 2021 and later, exposing users to potential data breaches involving credit card information, location tracking, and personal communications. With Apple working on mitigations, understanding the risks and adopting security best practices is crucial.

What Are FLOP and SLAP?

FLOP (Faulty Load Operation Prediction)

FLOP exploits the Load Value Predictor (LVP) in Apple’s custom silicon, allowing attackers to extract data from memory. By tricking the processor into mispredicting load values, FLOP can reveal sensitive information stored in memory, such as passwords and financial details.

SLAP (Speculative Load Address Prediction)

SLAP, on the other hand, targets the Load Address Predictor (LAP), enabling attackers to infer data from browser sessions. This flaw can be used to steal login credentials, autofill details, and other personal data accessed through Google Maps, Gmail, Proton Mail, and iCloud Calendar.

These vulnerabilities are particularly dangerous because they can be exploited remotely through malicious websites and web-based scripts, making unsuspecting users easy targets.

Devices Affected

Apple devices containing its custom-designed silicon, including the M1, M2, and M3 chipsets, are vulnerable. This includes:

  • Mac Books, iMacs, and Mac minis released since 2021
  • iPhones using A15 Bionic chips and newer
  • iPads using Apple silicon (M1 and M2 models)

If you own a device from this timeframe, your sensitive information may be at risk unless proper security measures are taken.

How These Vulnerabilities Can Be Exploited

Cybercriminals can take advantage of FLOP and SLAP vulnerabilities in several ways:

  1. Malicious Websites – Attackers can design websites that exploit these flaws when visited through Safari or Chrome.
  2. Browser-Based Data Leaks – Sensitive data like credit card details and login credentials can be accessed remotely through web-based attacks.
  3. Phishing and MITM Attacks – Cybercriminals can intercept unprotected network traffic to steal valuable information.
  4. Compromised Third-Party Applications – Exploits could be delivered via infected apps or browser extensions.

Apple’s Response and Mitigation Steps

Apple is actively investigating the issue and is expected to release security patches to mitigate the risks. However, because these vulnerabilities exist at the hardware level, software updates alone may not be a complete fix.

Until Apple provides a permanent resolution, users should take immediate action to secure their devices:

How to Protect Yourself

  1. Update Your Devices Regularly – Ensure macOS and iOS updates are installed as soon as they become available.
  2. Use Secure Browsers – Consider switching to browsers that prioritize security, such as Firefox or Brave.
  3. Disable Autofill Features – Prevent sensitive information from being automatically entered into compromised fields.
  4. Avoid Public Wi-Fi – Unsecured networks make it easier for attackers to exploit these vulnerabilities.
  5. Enable Two-Factor Authentication (2FA) – Strengthen account security by requiring an extra verification step.
  6. Monitor Bank and Email Accounts – Watch for unauthorized transactions or suspicious login attempts.

What This Means for Apple’s Security Future

While Apple has built a strong reputation for device security, these vulnerabilities show that even industry leaders are not immune to hardware-level risks. As Apple continues to push the boundaries of custom silicon design, cybersecurity will need to remain a top priority.

Apple users should remain proactive, stay informed, and adopt best security practices to reduce their exposure to these threats. Keeping software updated and implementing layered security measures will go a long way in protecting personal and business data from cybercriminals.

Conclusion

The discovery of FLOP and SLAP highlights the growing risks of speculative execution vulnerabilities in modern chip designs. While Apple is working on fixes, it is crucial for users to remain proactive in securing their devices. Regular updates, cautious browsing habits, and enhanced security practices are key to minimizing risks.

As technology evolves, so do the threats that come with it. Staying informed and taking necessary precautions will help users safeguard their sensitive data against emerging cybersecurity risks.
