Assuming a given SSD supports TRIM, and is on a physical bus that supports sending that command, and the connected computer is running an OS that is aware of TRIM:
If the drive is formatted, or has had its files erased, will the data be un… Continue reading Data recovery from TRIMmed SSDs
SK Hynix, one of the world’s largest chip makers, announced today it will pay $9 billion for Intel’s flash memory business. Intel said it will use proceeds from the deal to focus on artificial intelligence, 5G and edge computing. “For Intel, this transaction will allow us to to further prioritize our investments in differentiated technology […] Continue reading Intel agrees to sell its NAND business to SK Hynix for $9 billion
The card was a 16gb SanDisk micro SD card (monolithic).
SSDs seem to be notoriously tricky to properly erase (see for example this question and answers here). An easier and potentially safer solution could be to physically destroy the SSD device.
I am looking for a way to physically destroy an… Continue reading How to physically destroy an SSD at home?
To bypass a secure boot for System on Chip (SoC), some attacks target the phase of copying the bootloader from where it is stored to the main memory. Instead, a malicious code will be copied to the main memory. In that case, the bootloader… Continue reading Bypassing Secure Boot in System on Chip
I read in the answer here by Marcus that ROM is Tamper-proof.
What is the difference between tamper-proof, tamper protected and tamper-resistant?
Now, there are some re-writable memory (eg. eNVM) that can be configured to have some of … Continue reading Tamper Protected VS. Tamper Proof for write-protected memories
From an information security aspect, is there a difference between saying “read-only” or “write-protected” storage/memory?
Is there a chance that a read-only memory would not be write-protected at the same time?
In additio… Continue reading Read-only vs. Write-protected
An NES cartridge in its most basic form is a surprisingly simple device, it contains two ROMs hosting all the code and assets of its game, and a Nintendo code chip that provided what was a state-of-the-art consumer DRM system for the 1980s. Decades later its inner workings have been …read more

I purchased a used laptop on eBay.
I scrubbed the hard disk to make sure there were no lingering or unknown viruses left on the disk and then installed fresh Windows 10.
But, what about the firmware?
Does Windows Update ma… Continue reading How can I verify that my laptop does not have malware in the firmware?
I am aware of research which shows that single (or sometimes double) random overwrites on a magnetic hard drive is enough to ensure data is not recoverable, but is there any research into the recovery of data stored in an EEPROM after the … Continue reading Recovery of EEPROM data after bulk erase operation
