What is phishing ? Phishing is a form of fraud in which the attacker tries to learn information such as login credentials or account information by masquerading as a reputable entity or person in email, IM or other communication channels.

What is spear phishing ? Spear phishing is an e-mail spoofing fraud attempt that targets a specific organization, seeking unauthorized access to confidential data. Spear phishing attempts are not typically initiated by "random hackers" but are more likely to be conducted by perpetrators out for financial gain, trade secrets or military information.

Many at UNC-CH are careful, so thank you! Between March 16 and May 4 there were 4,459 phish reports to the ITS Service Desk. There seems to be plenty of awareness and cooperation from our community. So there is a lot of vigilance! Yet bad actors are still using phishing effectively.

Odd opening sentence and phrasing, as well as poor capitalization Odd opening sentence and phrasing, as well as poor capitalization. ConnectCarolina should be one word! Suspicious URL – two many non-UNC extensions. All caps message to create a false sense of urgency and fear. More poor phrasing. UNC Admin Verification Services does not exist.

UNC-CH organization will EVER ask you for your Onyen and password. No authorized UNC-CH organization will EVER ask you for your Onyen and password. EVER.

What can we do about Phishing? Understand what a phish looks like & be cautious Report the phish: phish@unc.edu Hover to discover the real URL destination
