How to Protect Yourself from Ransomware

Store your business-critical files on Microsoft OneDrive, or in the case of confidential data, on your departmental network share

UITS centrally manages patches for university devices. If you're unsure whether your device is being patched, details are available on the UITS website linked at the end of this training

UITS centrally manages antivirus defense for university devices. Forward suspicious emails to UITS at [email protected] or simply delete them

Only install applications from trusted sources; If you're not sure, reach out to the Service Desk

Practice safe web browsing: Make sure a URL includes HTTPS before entering any personal

information Don't click on pop-up windows or extraneous ads Use re-use your NetID password for other accounts. Use a strong, unique password or passphrase for each account,

and avoid storing account information on a website

Email Scams

Protecting Yourself from Email Scams

Merriam-Webster defines Phishing as: “a scam by which an Internet user is duped (as by a deceptive email message) into revealing personal or confidential information which the scammer can use illicitly.”What to look for and how to respond: Look for spelling and grammatical errors in the email. Do not click on any link provided in an email if you are unfamiliar with the

sender. Always check the source of any gift card request, by calling the requestor. Get a questionable account update email? Take action...

Report scamming attempts to [email protected]. Delete them!

Final Note: If you discover you have been a scam victim, change your password and report the incident to [email protected]. If you are unsure, contact the KSU ServiceDesk

SMS Scams

It’s Tax Season: Mobile Scams are Coming.

A recent SMS phishing scam has surfaced in the UK where bad actors are informing some citizens that they are recipients of a refund due to “overpayment” and instructed them to “click a link” to begin the process.

What made it more successful than others in the past?

1. Realistic-looking website. 2. Inclusion of current events, such as coronavirus. 3. Proper verbiage was used. 4. They knew their audience. Since it was a UK scam,

they asked for the victims “National Insurance Number,”as opposed to an SSN for U.S. residents.

The Truth is...

“The IRS doesn't initiate contact with taxpayers by email, text messages or social media channels to request personal or financial information. This includes requests for PIN numbers, passwords or similar access information for credit cards, banks or other financial accounts.”

"The IRS will never initiate contact with taxpayers via email about a tax bill, refund or Economic Impact Payments."

Data Classification and use

Can I Store or Email…? Refer to the KSU Document Management Matrix* Confidential Data - the most restrictive data classification Sensitive data requires special precautions to protect from

unauthorized use, access and disclosure, guarding against improper information modification, loss or destruction.
