The AT&T vishing scams are still going around. AT&T subscribers are reminded to visit only the official AT&T website, www.att.com, for matters concerning their phones or billing statements.

Below is a list of caller numbers confirmed to be vishers:

  • (800) 750-1231
  • (800) 296-1986
  • (800) 277-5319
  • (800) 157-2868
  • (800) 324-1933
  • (800) 194-1207
  • (800) 144-2591
  • (800) 970-2089

If anyone calls to inform you that you’ve been awarded credit or a discount on your next month’s billing statement, just hang up. Do not visit the link they provide.

So do you remember the last time vishers paid us a visit? They’re at it again. I got a call from 800-970-2089 trying to direct me to www.yougoatt.com for a “free” $100.

Yeah. Free money. Also comes with free malware.

This call is another reminder that scammers will try to trick you into revealing your personal information through any medium. Most of UD knows about email phishing scams, the most common route; however, phone, social media, and text scams are multiplying. All with the aim of luring you to surrender enough information about yourself that the scammer can use your personal information for fraudulent purposes.

I just got an interesting phone call. The caller ID showed me 800 number – (800) 344-3089 – telling me that I had just won $200. That’s pretty sweet. I could use some money.

Sadly, this seems like a vishing scam; we’ve previously discussed similar incidents. It was an automated caller, and it tried to direct me to attbonus200.com to claim my money. That doesn’t seem legit, and I’m not going to risk a laptop and my identity for a $200 “freebie.” The laptop and all my data are worth more.

The UD VoIP system has a feature that allows its users to forward voicemails to email. However, before it can be functional, UD staff must personally request this feature be set up by Telephone Services–it is not automatic. If you have not requested this feature be set up, and you receive a voicemail in your inbox, it is a scam.

Scammers are trying to take advantage of this feature and are starting to send malware, disguised as voicemail, to infect your computer.

The same method can get you to reveal personal information. Even if you do not download any files, simply responding to the message with a call or email can reveal enough information to scam you.

Here are some things to look out for when you have a voicemail in your inbox:

  • You need to sign up for this feature. If you did not ask for this feature and received voicemails in your inbox, it is a scam.
  • Messages are sent from UNITY@udel.edu.
  • Unity does not send group messages.
  • Attachments from Unity are .wav files, not .zip files.
  • Be aware of “Unknown Caller.” Usually there will be a name or “wireless caller.”

There have been several email messages using  phishing style attacks to scam you. Even though these two messages look different, they are trying to scam you in the same way:

This message is using the traditional phishing scam approach. There are several discrepancies that make it a scam such as the terminology, “your email address seems infected.” However, instead of getting you to click on a link, they are trying to get you to call a number.

This message is using a spam technique. Once again, there are no links to click on, you have to call a number.

Notice anything familiar about these messages? They list the same phone number, despite being from different companies. Instead of traditional phishing and spam scams, that want you to click a link, these messages want you to call a phone number. The phone numbers all go to a scammer and that is how they will get you.

Now that students, employees and faculty are becoming more adept at spotting the obvious phishing scams, scammers are changing their social engineering tactics. The scammers will talk to you or reply to your messages so you feel more sympathetic towards them and become more inclined to give them money or personal information.
