In the midst of significant layoffs hitting the previously immune tech industry, scammers have mobilized and doubled down on targeting job seekers with various employment scams. Stealing personal information and extorting victims for money, these scams leverage fake job postings, sites or portals, and forms, wrapped in social engineering to attract job seekers.
The Zscaler Threatlabz team observed multiple suspicious job portals and surveys used by attackers to solicit information from job seekers under the guise of employment application forms. The attackers may advertise jobs online, sometimes setting up fake websites, or look for targets on social media to steal money and personal information.
- Threat actors masquerade as recruiters from specific companies, primarily located in the US and Canada.
- Malicious new domains are registered on hosting providers like Namecheap.
- Attackers scrape and reuse the contents of real job postings from public sites like SmartRecruiters and LinkedIn to convince applicants the post is legitimate.
- Fake application forms steal sensitive personal information from victims and may be sold, used for fraud, and to further target and extort victims.
- Newly Registered Domains (NRD) are commonly used by threat actors and these have suspicious Top-Level Domains (TLDs) such as .online, .work, .live, etc. typically followed by the name of the actual hiring organization the attackers are impersonating.
Threat Campaign Analysis
Our researchers discovered an active scam where the threat actor(s) positioned themselves as Zscaler recruiters targeting job seekers on LinkedIn.

This fake listing was created by a scammer from an active Zscaler job posting listed on SmartRecuiters, however the attackers made one change, lowering the years of experience requirement to attract more potential victims. For an unsuspecting candidate, this common outreach tactic may feel familiar and the copied job posting appears like a legitimate position.

To apply for the fake job shown above, applicants are prompted to fill out a questionnaire that requests personal information, job role related information, and compensation information.

As a final step of the questionnaire, the victim is prompted to verify identification by uploading a copy of their State ID, Drivers License, Residential Permit, or Passport. Collecting this document along with the victim's other personal information may enable the scammers to impersonate the victim committing identity theft and fraud, or sell the information to other scammers.

After submitting the completed questionnaire, a confirmation message is displayed indicating the victim will be contacted via text message or email in 1-3 days for next steps in the application process.

Once the submission has been received by the scammers, they reach out using email to schedule a fake interview using Skype or a chat application, as shown in the screenshot below.

Following the fake interview, candidates may receive a fake job offer and be routed through a fake onboarding process. As a final step, victims may be asked to pay for shipping the IT hardware equipment they will need for the remote position or payments for onboarding training. Scammers may also ask for Social Security numbers and bank account information for depositing paychecks.
The malicious site observed in this threat campaign contained currently inactive code to validate credit card details, a feature that may be used once a victim falls for the initial attack.

The malicious domain used in this scam - zscaler-finance-analyst-strategy[.]live, was created on 23-Jan-2022, a Newly Registered Domain at the time of technical analysis by Threatlabz researchers on 24-Jan-2022, following an observed attack one day after the domain was created.

A script found in the site’s code contained an email address impersonating a Netflix recruiter with domain jobnetflix[.]com.
Conducting a pivot search on this email address, researchers discovered the following two additional fake job postings leveraged by the same unauthorized email account:
- UX designer (REMOTE) ZUORA SOFTWARE
- Project Administrator Construction, New Equipment KONE OYJ

Best practices to safeguard against these attacks:
- Ask for a direct link to the company’s job posting and reach out to the company directly using contact information you gather from the company website to verify the credibility of a job posting. Search for job postings across legitimate job sites. Only submit online applications to authentic verified sites.
- Do not engage in communication with any un-official email address or respond to a text or phone number without verifying legitimate company affiliation for the recruiter and confirming via email communication that they have a corporate email address.If you’re not familiar with the company, search its name with the word “scam” or “fraud.” You may find stories from others who have been targeted.
- Look for telltale signs of a possible scam like emails from personal email addresses or email addresses not affiliated with the company, grammar and spelling mistakes, interviews conducted solely via email or online chat, salaries out of line with industry norms, and requests for financial information or other personal information.
- Never make any type of payment for an application or job offer. Genuine organizations will never ask you for any type of payment to apply or accept a job offer. Likewise, legitimate recruitment agencies and placement firms are almost always compensated for sourced candidates by the companies they serve. Any request for payment should automatically raise a red flag that you are likely dealing with a scammer.
- Only use HTTPS/secure connections when visiting job postings.
- Ensure your operating system and web browser always have the latest security patches installed.
