Phone Scam Alert “Wangiri”

A widespread automated phone scam dubbed “Wangiri”, which is Japanese for “one ring and drop”, is using automated dialing machines to repeatedly dial phone numbers one time before hanging up. Incoming calls may appear to come from a variety of phone numbers, including “unknown caller”, “no caller id”, or spoofed domestic or international phone numbers. Calls may even appear with three digit area codes that appear to be domestic, but are associated with pay-per-call international phone numbers. The goal is to get the recipients/victims to call back and remain on the call as long as possible, while the call is routed to a premium rate service which can charge a connection fee and then bill victims for significant per minute charges.

As it is not possible to block calls that are received from an “unknown caller” or “no caller id”, it is recommended that you do not answer unexpected calls, calls that you suspect may be spoofed, or return calls coming from unexpected or unknown phone numbers. If you return a call to an unknown number and hear an odd message, it is recommended that you immediately hang up. Further, if you do not frequently make international calls, you may want to consider asking your service provider to block all outgoing international calls.

Please see the following NJCCIC blog post for carrier specific call blocking options: Tired of Receiving Scam Calls? Don’t Just Sit There. Do Something About It. Additionally, if you have been a victim of an international phone scam, you can file a complaint with the Federal Trade Commission (“FTC”) at www.ftccomplaintassistant.gov.

Scammers Use Recent Disasters to Spread Malware

Please be advised that scammers use reports of recent disasters, such as the recent Boeing 737 Max crash to spread malware. With respect to this recent crash, spam messages appear to be coming from a purported private intelligence analyst, “info@isgec.com”, who is claiming to share information found on the dark web about other airlines that will soon be impacted by similar crashes. The email requests that recipients forward the email to loved ones. The email attaches a JAR file, which if opened, is believed to install the Houdini H-worm remote access trojan (“H-Worm RAT”), which can provide remote control of a device to a malicious actor, and Adwind, which is an information stealing trojan.


  • Refrain from forwarding unsolicited emails to others
  • Do not open unexpected attachments
  • Do not click embedded links in unexpected email messages
  • When in doubt, confirm the legitimacy of a message with the sender via a trusted means of communication, such as a known phone number

NYU Box: Reduce Unintended Disclosure via Link Sharing

Screenshot showing the above-described NYU Box dialog

Please be advised/reminded that if you select, “People with the link” as your share setting you are making the data contained in the folder/file publicly accessible to not only those provided with the link, but anyone who discovers the link. Public folders/documents can be scraped and indexed by search engines, making them easily found. Therefore, it is recommended that if you choose “People with the link” as your share option for any file/folder you additionally visit “Settings” via the gear icon on the top right of the dialog (as shown below), and select either the “Require password” or “Disable Shared Link on” option.
