DO NOT REPLY TO THIS PHISHING EMAIL!

This phishing campaign is designed to collect students’ personal information. A reply confirms that your account is active and could lead to more spam. Additionally, if you provide your alternate email address and phone number as requested, you could be vulnerable to phone and text message scams in addition to being pressured by the fake employers for more personal information.

This job scam is similar to a COVID-19 themed variant reported in early May. While the message and subject of the emails have changed, the basic premise has not. See the original post at https://itsecurity.umbc.edu/critical/?id=92997.

During the  COVID-19, unemployment numbers have been rising and more people are looking for work. Some people have unknowingly gotten involved in breaking the law. According to the article from Idaho News 6 linked below, police found thousands of dollars worth of stolen merchandise in a garage belonging to a homeowner who thought he was renting space to people  working on a reshipping job.

The article warns that malicious actors post legitimate looking “work from home” help wanted or job openings on places like social media, message boards and even job posting sites. These ads will claim the work will be easy, pays big, and can be done from home. The malicious actor uses stolen credit cards to purchase goods and has the victim reship the items. In fact, the malicious actor is using the victim as part of a money laundering operation.

The article encourages readers to stay safe while job searching, to make sure that the employer has a readily available phone number for human resources, and has a company website. Scammers on the other hand usually will communicate through email or messenger only and are very secretive about the work, their business, and what the employee will be doing. The article also warns against paying upfront fees since malicious actors will often ask for fees for background checks or other pre-employment checks.

Next Week, Maryland will begin a state-wide effort to trace the spread of COVID-19.  The effort will involve health workers making phone calls to Maryland residents.  This is a very important step in identifying potential disease clusters and everyone’s help is needed.

At the same time, Maryland in general and UMBC in particular have been targets of a wide variety of scams taking advantage of people’s fears and uncertainties around this disease.  It is very possible that unscrupulous people will take advantage of Maryland’s effort as a cover for phone scams.  North Carolina, for instance, started a contact tracing effort last month and has gotten reports of scammers pretending to be health officials and gathering information from residents.

Phone Calls

When you get a call, your caller ID should read “MD COVID”.  You will be asked about your health and about your location and interactions within a period of time.  You will be asked for your birth date, contact information, and information about any COVID-19 test if you have had one.  You will get guidance about potential symptoms to watch for and about self-isolation.

You will NOT be asked for:

• ·        a Social Security number

• ·        financial or bank account information

• ·        personal details unrelated to COVID-19

• ·        photographs or videos

• ·        passwords

• ·        payment

If anyone asks you for this or other information having nothing to do with COVID-19, please do not give it to them. 

Text Messaging

So far, Maryland has not announced that text messaging will be part of the contact tracing effort.  If you receive a text message that asks you to click on a link for contact tracing, do not click it. At best, it will take you to a scam questionnaire requesting your personal information.  Worse, it could download malware to your phone and start harvesting personal information itself.

New Jersey has received reports of text messages pretending to be from contact tracers and telling people that they have already had contact with a potential COVID-19 carrier.  These messages also contain links which will lead to information theft and/or malware.  Contact tracers don’t work like this.

Android Ransomware

DomainTools discovered that domain names associated with COVID-19 and Coronavirus have spiked in the past few weeks, and many of those domains are considered malicious. One that caught their eye was a website that offers a real-time coronavirus outbreak tracker as an Android app.

The app says that it offers many features like a heat map and other statistical data about COVID-19, but this app is instead ransomware. When downloading the app, it will ask for administrative access promising that this will allow certain types of information. If the app is given administrative access, it is given the opportunity to lock up all contacts, pictures, videos, and social media accounts unless their ransom is paid in Bitcoin. If the ransom is not paid, the attacker threatens to release all private information publicly and erase the phone's memory.

DomainTools offers tips on how to better protect against ransomware and other malware that tries to capitalize on coronavirus. They first state to be sure to only use trusted information sources from the government and research websites, and not to click on anything health related in your emails. Next they ask Android users to ensure that they download apps from the Google Play store, as third-party stores have a much higher risk of downloading malware.

Tripwire has released an article warning of these COVID19-related phishing scams. This article can be found at this link: https://www.tripwire.com/state-of-security/security-awareness/covid-19-scam-roundup-may-11-2020/

(Fake) Work From Home Offers

PhishLabs discovered a phishing email attack aiming to entice people laid off due to COVID-19 with a work from home opportunity. The one email they found offered $5000 a month for a fake position. If the reader replies, they are asked for personal and financial information and will be given a more detailed job description involving transfering money through the readers accounts. The malicious actors might not only steal money from the readers account, but also could use the reader as a money mule meaning that they could be held liable for the stolen money that passes through their account. 

(Fake) IRS Page

Researchers at SecureWorks discovered malicious actors targeting readers with a phishing page designed to look like a tax form given by the IRS. The attack is believed to be distributed through email attacks, and the goal of this attack is stealing the readers tax information. Once the malicious actor has the information, they can then impersonate the reader on the official IRS tax form meaning that they will collect not only their tax return but their stimulus checks as well.

Impersonating Institute of CPAs

The Microsoft Security Intelligence team discovered that some digital attackers were using COVID-19 themed attack campaigns to distribute malware. One example they found showed a malicious actor impersonating the Institute of CPAs. In their emails they were claiming to be delivering COVID-19 related updates to its members as well as containing a ZIP file. The file is instead an executable that will allow the malicious actor to take control of the affected machine.
