Be careful what links you click on. URL shortening services like bit.ly
are doing a “great job” masking the final destination of your click. You
can unwittingly land on a server which is hosting phishing sites or
pages distributing malware. Cybercriminals have
made Twitter their favorite phishing target now, and they often will send @
messages to users that look like they contain information of interest or come
from a username that’s slightly different from someone you follow.
