Cryptographic Graveyard: Data remanence, invisible security crisis of discarded electronics by Remmy Nweke - WeekendDigits@ITREALMS

In this final installment of the WeekendDigits@ITREALMS e-waste trilogy, REMMY NWEKE examines a less visible but potentially devastating dimension of the global e-waste crisis: the sensitive data that may survive inside discarded electronic devices.

While public attention rightly focuses on the black smoke rising from Lagos dumpsites and the toxic heavy metals entering the environment, a quieter threat is taking shape within Nigeria’s informal electronic-waste economy.
