When Deleted Isn’t Gone — Privacy Risks in Electronics Repair
- The electronics repair industry, valued at around $19 billion globally, lacks sufficient regulatory oversight on customer privacy, leading to data exploitation risks.
- Recent research indicates that repair technicians frequently access and even share customers' private data, such as personal photos and videos, despite it being unnecessary for the repair task.
- Customers' assumption of deleted files being permanently erased is debunked, as skilled technicians can easily recover such data due to the technical aspects of data storage.
- Various studies highlight a high incidence of privacy violations within the electronics repair sector, with a significant percentage of technicians found to snoop on data or copy it without consent.

Spear Phishing - The Targeted Cyberattack You Need to Watch Out For
- Spear phishing is a targeted form of phishing where cybercriminals craft tailored messages to deceive individuals or organizations by appearing as a trusted source.
- The attacks are personalized and often aim to trick victims into revealing sensitive information, clicking malicious links, or downloading malware-infected attachments.
- Spear phishing is harder to detect than generic phishing and requires vigilance. Practical steps to protect against it include verifying requests independently, enabling Two-Factor Authentication (2FA), limiting public information, and using anti-phishing tools.
- In 2025, spear phishing is expected to leverage artificial intelligence for creating hyper-personalized messages. Staying aware, verifying requests, and securing accounts are crucial in defending against these evolving threats.
