As the technology that recognizes and thwarts malware becomes more advanced, hackers are finding it much easier to trick overly trusting humans to do their dirty work for them. Known as social engineering, it’s a dangerous trend that is becoming increasingly prevalent.

Fancy Bear, also known as APT28, is the Russian cybercriminal group responsible for hacking the Democratic National Party last year. Since then, the group has developed a host of tools to exploit Linux, Android, and Windows vulnerabilities. Last month, they spread a new strain of malware that specifically targets Apple Macbooks.
