The past several weeks have seen numerous articles about the spread of malware via fake Ebola-related emails. Hackers will imitate the CDC, WHO, or major news outlets like CNN to spread dangerous links. Shocking headlines -- "Ebola virus has been cured!" -- entice people to click, resulting in compromised devices and accounts.
The ploy is not limited to email. Social media have also been used to disseminate dangerous information and manipulate users following the Ebola story. Hackers append trending hashtags, most commonly #Ebola, to amplify the scope of their attack -- a tactic known as trendjacking.
