Ransomware is a type of malware that locks access to data or devices until an attacker is paid. This can create major financial and security problems for older adults, families, and businesses. A cybersecurity expert, Dr. Christopher Whyte, recommends a "zero trust" approach to protect against cyberattacks.

This approach involves being cautious of potential threats, including phone calls from unverified sources. Dr. Whyte explains that zero trust is a set of principles that assumes security measures are not enough to guarantee safety.

Further information on the zero trust approach and how to protect against cyberattacks is available from the source.
