📌 Rowhammer Attacks Summary
Rowhammer attacks are a type of cyberattack that target the physical memory chips in computers, especially DRAM. By rapidly and repeatedly accessing specific rows of memory, attackers can cause tiny electrical disturbances that flip bits in nearby rows. This can lead to unauthorised changes in data, potentially allowing attackers to bypass security measures or gain higher privileges.
🙋🏻♂️ Explain Rowhammer Attacks Simply
Imagine banging on a wall so hard and so many times that things start falling off the shelf in the next room. Rowhammer attacks do something similar to computer memory, causing changes in neighbouring areas just by repeatedly accessing the same spot. It is a sneaky way to mess with a computer’s memory without directly touching it.
📅 How Can it be used?
A cybersecurity project could use Rowhammer attacks to test whether a system’s memory is vulnerable to this kind of physical attack.
🗺️ Real World Examples
In 2015, researchers demonstrated that Rowhammer attacks could be used to gain administrative access on some laptops by flipping bits in memory and altering permission settings, even without direct software vulnerabilities.
Cloud service providers have faced risks from Rowhammer attacks because multiple customers share the same physical hardware, making it possible for one user to potentially attack another’s virtual machine by manipulating shared memory.
✅ FAQ
What is a Rowhammer attack and why should I care?
A Rowhammer attack is a clever trick hackers use to mess with the memory chips in computers. By rapidly tapping certain parts of the memory, they can make tiny changes that were never supposed to happen. This could let someone change important information or even sneak past security without the usual permissions. It is a reminder that even the hardware inside your computer can have its own weak spots.
Can Rowhammer attacks affect my laptop or phone?
Yes, Rowhammer attacks can potentially affect any device that uses certain types of memory chips, like many laptops, desktops, and even some smartphones. While not every device is vulnerable, and tech companies have made changes to help protect against these attacks, it is still a good idea to keep your devices updated and be aware of the risks.
How do people protect computers from Rowhammer attacks?
To protect against Rowhammer attacks, manufacturers have started using stronger memory chips and adding new checks that make it harder for hackers to change data this way. Software updates can also help by making it tougher for attackers to pull off their tricks. Staying up to date with patches and using reliable hardware goes a long way in keeping your devices safe.

💡Other Useful Knowledge Cards
Workflow Loops
Workflow loops are repeating steps within a process that continue until certain conditions are met. These loops help automate tasks that need to be done multiple times, such as checking for new emails or processing a list of items. By using workflow loops, teams can save time and reduce errors in repetitive work.
Threat Detection Automation
Threat detection automation refers to the use of software and tools to automatically identify potential security threats in computer systems or networks. These systems scan data, monitor activity and use set rules or machine learning to spot unusual or suspicious behaviour that could indicate a cyber attack. Automating this process helps organisations respond faster to threats and reduces the need for constant manual monitoring.
Entropy Scan
An entropy scan is a method used to detect areas of high randomness within digital data, such as files or network traffic. It measures how unpredictable or disordered the data is, which can reveal hidden information or anomalies. High entropy often signals encrypted or compressed content, while low entropy suggests more regular, predictable data.
Inclusion Metrics in HR
Inclusion metrics in HR are ways to measure how well a workplace supports people from different backgrounds, experiences and identities. These metrics help organisations understand if all employees feel welcome, respected and able to contribute. They can include survey results on belonging, representation data, participation rates in activities and feedback from staff.
Soulbound Tokens (SBTs)
Soulbound Tokens (SBTs) are a type of digital token that cannot be transferred from one person to another once they are issued. Unlike typical cryptocurrencies or NFTs, SBTs are designed to represent personal achievements, credentials, or memberships that are unique to an individual. They are stored in a digital wallet and function as a permanent record, similar to a digital certificate or badge.
