Chegg Breach (09/26/2018)
Chegg, a textbook rental and online tutoring company based in Santa Clara, plans to reset passwords for 40 million users following the discovery of a breach dating back to April 2018. From Chegg's web site: "An unauthorized party gained access to a Company database that hosts user data for chegg.com and certain of the Company's family of brands such as EasyBib." Chegg said the hacker(s) "may have" gained access to user data such as names, email addresses, shipping addresses, Chegg.com usernames, and Chegg.com passwords.
Although passwords were hashed which should mean they are protected, it is important to change your password in Chegg and in any other application where you used the same or similar password. Always remember to use a separate password for each application or site you are enrolled in.

Back to School Security Tips (08/27/2018)
Welcome back to school. Here are some security tips to keep your data safe as you start a new semester at CSUN.
- Stop.Think.Click. Phishing and other malware scams rely on our habit to click first, think later. Phishing scams can be incredibly believable. We have many examples on our phishing web site. Please have a look. Hackers can be very clever.
- Be careful with social media: Make sure you understand who can see your posts.
- Place a fraud alert on your credit report: This will limit the damage caused by identity theft.
- Turn off Flash: Flash Player is popular with hackers. They exploit Flash by inserting malicious bits of code into ad networks used by well-known businesses.
- Check your apps: Mobile applications can only do what you let them do. Review permissions on your apps.
- Keep programs up-to-date: Most applications on all of your devices have automated update features. Turn them on.
- Use unique passwords: A single password used on all of your sites is a hackers best friend. A password can be stolen from an unimportant game with lax security site can then be used to hack into your bank account and other important sites, only to be used to break into one's bank accounts. Unique passwords limit the damage to one site. Also consider using a password manager.
- Think before you click. - see #1. It's important.
We are receiving information from our higher education information security intelligence sources that there is a blackmail/phishing scam hitting multiple higher edu institutions around the country including the UC. We have not been advised of any attempts against CSU campuses so far.
This particular attempt is a form of what is known as “Sextortion.” The scam, in most cases, displays a password that may appear to be or actually be a user’s password that the sender claims to have been obtained from an adult content website. The passwords were actually harvested from breaches of companies in the past, some as long as a decade ago and hackers have posted the credentials on the DarkWeb or sites like PasteBin. These are sites used by hackers to trade, sell and display credentials they have compromised.
The current scam purports to have obtained the user's password from an adult (porn) site and threatens to reveal the users online behavior to others unless a ransom is paid in Bitcoin (internet currency).
The FBI advises:
- Never send compromising images of yourself to anyone, no matter who they are — or who they say they are.
- Don’t open attachments from people you don’t know, and in general be wary of opening attachments even from those you do know unless they are expected.
- Turn off [and/or cover] any web cameras when you are not using them.
Please report the receipt of any of these messages or similar phishing attempts to the Support Center: firstname.lastname@example.org

Post Office Mail Scam (2/26/2018)
The USPS has a service that allows you to see a preview of your snail mail on-line. Unfortunately when the USPS rolled this out their identity verification was lax and there was no notification sent to the mail owner that someone signed up. Therefore, it was easy for scammers to sign up to get a preview of your mail and know when credit cards, bank statements or checks were delivered. The USPS has implemented a new notification system to alert you when someone signs up. It is suggested that you sign up for this notification process.

Chrome Browser Scam/Ransomware (2/8/2018)
Security researchers are reporting that hackers are exploiting a bug in Chrome to try to extort money from unsuspecting users. The way it works is that upon navigating to a hacked or invalid web site, your browser may display a message telling you to call a number and then lock up the browser and eventually your Windows machine. If you do encounter this issue on Windows you may use Task Manager to kill the Chrome browser or you can reboot your machine. On MacOS your Mac will eventually tell you that your browser is unresponsive. Under no circumstances should you call the number popping up on your machine. Chrome has not yet issued a patch.
