Fake job interview emails installing hidden cryptocurrency mining malware

The job market hasn’t been great in the last few years, especially in tech, leaving a lot of people actively looking for jobs. 

Scammers are taking advantage of this. They have come up with a new trick where they pretend to be recruiters to spread crypto miners on people’s devices. 

It starts with an email inviting the person to schedule an interview for a job. But when they click the link, it installs a malicious app that secretly mines cryptocurrency. This app hijacks your PC’s resources, like the CPU and GPU, which slows down its performance significantly.

What you need to know

This malicious campaign begins with an email that tricks victims into thinking it is part of a recruitment process, as reported by Dark Reading. In most cases, these emails are pretending to be from recruiters at the cybersecurity company CrowdStrike.

The fraudulent email contains a link claiming to take the recipient to a site where they can schedule an interview. However, in reality, it redirects the victim to a malicious website that offers a download for a supposed “CRM application.”

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

The site provides download options for both Windows and macOS. Regardless of which option the victim selects, the download will be a Windows executable written in Rust. This executable then downloads the XMRig cryptominer.

The executable performs several environmental checks to analyze the device and avoid detection. It scans running processes, checks the CPU and more. If the device passes these checks, the executable will display a fake error message while secretly downloading additional payloads needed to run the XMRig miner.

How does a cryptominer affect your PC?

A cryptomining app can significantly impact your PC’s performance. Once installed, it hijacks your computer’s resources, including the CPU and GPU, to secretly mine cryptocurrency. This process requires a lot of computational power, which can cause your system to slow down drastically. You might notice your computer becoming unresponsive, running hotter than usual, or consuming more power. 

In some cases, prolonged use of cryptominers can also lead to hardware damage due to the increased strain on your components. Additionally, these miners often run in the background without your knowledge, making it harder to detect the issue until the damage is already done.

CrowdStrike is aware of the scam and advises individuals to stay vigilant. “This campaign highlights the importance of vigilance against phishing scams, particularly those targeting job seekers. Individuals in the recruitment process should verify the authenticity of CrowdStrike communications and avoid downloading unsolicited files, the company said in a blog post

BEWARE OF ENCRYPTED PDFS AS THE LATEST TRICK TO DELIVER MALWARE TO YOU

5 ways to stay safe from job interview scams

1. Check if you applied for the job: If you receive an unsolicited interview invitation, think back to whether you actually applied for that job or company. Scammers often target jobseekers randomly, hoping someone takes the bait. If you didn’t apply, it’s likely a scam. Always confirm directly with the company before proceeding.

2. Verify recruiter credentials: Always double-check the recruiter’s details before responding to an email or clicking any links. Verify their email address, LinkedIn profile and company association. Legitimate companies will use official email domains, not free services like Gmail or Yahoo.

3. Avoid downloading unsolicited files: Be cautious of emails asking you to download any files or applications. Legitimate recruitment processes rarely require you to install software. If unsure, contact the company directly to confirm the request.

4. Inspect links before clicking: Hover over any links in the email to see their actual URL. Scammers often use URLs that mimic legitimate sites but have subtle differences. If a link looks suspicious, avoid clicking on it.

5. Use strong antivirus software: Use strong antivirus or endpoint protection software to detect and block malicious downloads. Regularly update your security tools to ensure they can handle new threats effectively.

The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.

WHAT TO DO IF YOUR BANK ACCOUNT IS HACKED

Kurt’s key takeaway

Cybercriminals always manage to come up with new ways to exploit people. While this particular scam is more focused on using your computer’s resources than stealing data, it is still very dangerous. It shows that if a hacker can easily install software on your PC, they can also go ahead and steal your financial information and other personal data. Always verify the emails you receive, and try not to download anything you don’t trust.

Grandparents are identity theft’s biggest payday

Grandparents are identity theft’s biggest payday

NEWYou can now listen to Fox News articles!

The FBI calls it a “distress scam.” It is also known as a grandparent scam. The scam works by making an older adult believe a grandchild is in serious trouble and needs money right away, often before a court date or legal deadline. Victims reported more than $5 million in losses to this type of fraud in 2025. The FBI’s Internet Crime Complaint Center also noted that reported losses likely show only part of what scammers actually stole.

The Federal Trade Commission found in August 2025 that some of the fastest-growing scams targeting older adults use fear and urgency to override good judgment. A caller may claim your bank account was hacked and say you need to move your money immediately to protect it. However, the money does not move to safety. It goes straight to the scammer.

HOW TO HAND OFF DATA PRIVACY RESPONSIBILITIES FOR OLDER ADULTS TO A TRUSTED LOVED ONE

AI voice-cloning tools have made these scams even more convincing. Scammers can use a birthday video, voicemail or social media clip to mimic a grandchild’s voice. Then they place the call. The voice sounds familiar, the emergency feels real and the request for bail money seems urgent. The FBI counted $352 million in AI-related scam losses among victims 60 and older this past year.

What makes grandparents worth targeting

The same three pieces of data are required for identity verification at most banks, brokerages, pension recordkeepers, and Medicare: date of birth, last four digits of a Social Security number, and a current mailing address. For most people in their sixties and seventies, all of those accounts are open.

Those three fields have turned up in breach after breach. The Conduent Business Services breach pulled names, SSNs, dates of birth, and home addresses for more than 25 million Americans from systems that process Medicaid records and employer health plans. Texas Attorney General Ken Paxton called it the largest data breach in U.S. history in February 2026.

Americans between 65 and 74 held a median net worth of $409,900 in 2022, according to the Federal Reserve’s Survey of Consumer Finances, more than ten times the median for adults under 35. The FBI found average losses of approximately $38,500 per victim among Americans 60 and older in 2025, nearly double the figure for younger filers.

Why elder fraud losses are often underreported

Older adults reported $2.4 billion in fraud losses to the Federal Trade Commission in 2024. However, the FTC’s December 2025 report to Congress estimated that real losses may have reached $81.5 billion that year. Most cases likely went unreported.

That gap makes identity theft harder to stop. A fraudulent wire from a pension account may never alert a bank. A new credit account opened with stolen information may not reach the victim until it appears on a credit report. By then, weeks may have passed since the application was approved.

Account protections worth setting up

Scammers move fast, so it helps to set up account protections before anything goes wrong. These steps can give banks, brokerage firms and family members more ways to spot trouble early.

1) Add a trusted contact to brokerage accounts

Brokerage accounts have a protection option many account holders never activate: a trusted contact designation. Under FINRA Rule 4512, brokerage firms must ask for a trusted contact when you open or update an account. A trusted contact can be a family member, attorney or accountant. The firm can contact that person if it suspects financial exploitation or cannot reach you. However, that person cannot trade, withdraw funds or view your account balances. FINRA, the SEC and the North American Securities Administrators Association asked investors in August 2025 to contact their firm and add one. You can name more than one trusted contact. You can also change the designation at any time.

2) Ask about holds on suspicious withdrawals

Under FINRA Rule 2165, brokerage firms can place a temporary hold on disbursements when they reasonably believe financial exploitation may be happening. That hold can last up to 55 business days. In January 2026, FINRA proposed extending the window to 145 business days. Ask any firm holding a pension, brokerage or annuity account about its policy on disbursements after an address change.

3) Verify urgent calls before sending money

When a caller claims a grandchild is in trouble or a federal agent needs immediate action, hang up. Then call back using a number you already have, not the number in the message. The FTC found that 41% of older adults who reported losing $10,000 or more to impersonation scams in 2024 said a phone call was the initial point of contact. That makes one simple habit especially important: verify the story before you act.

4) Block online changes to Social Security

Social Security lets you block electronic and automated telephone access to your account record. Once blocked, no one can change your direct deposit information or mailing address online or through the automated phone system. After that, any changes must go through a live SSA representative at 1-800-772-1213 or a field office visit. FINRA also operates a free Securities Helpline for Seniors at 844-574-3577, Monday through Friday, 9 a.m. to 5 p.m. ET.

Identity theft recovery is harder on your own

Even strong account protections may not catch every scam attempt. That is why identity theft monitoring and recovery support can help families respond faster when personal information gets exposed or misused.

Some identity theft protection services monitor dark web marketplaces, data broker sites and people-search sites for exposed Social Security numbers, addresses and other personal information. If fraud happens, recovery support may help contact creditors, file disputes with the three credit bureaus and organize the documentation needed to restore an identity.

OUTSMART HACKERS WHO ARE OUT TO STEAL YOUR IDENTITY

Some plans also include identity theft insurance for eligible recovery costs, such as lost wages and legal fees.

No service prevents every misuse of an older adult’s identity. However, family monitoring and fraud resolution can shorten the time between when theft happens and when you or someone in your family acts on it.

Kurt’s key takeaways

Grandparents have become a prime target because scammers know where the money is and how to create panic fast. A familiar voice, a stolen Social Security number or a fake emergency can turn one phone call into a devastating loss. The best defense starts before the call comes. Add trusted contacts to financial accounts, block online Social Security changes, verify urgent requests through a number you already know and talk openly with family about scam warning signs. Identity theft protection can also help spot exposed personal information and speed up recovery if fraud happens. No family can stop every scam attempt. However, a simple plan can give older adults more time, more backup and a better chance of keeping their money safe.

A warrantless wiretap law is about to expire — but surveillance networks aren’t actually ‘going dark’

A warrantless wiretap law is about to expire — but surveillance networks aren’t actually ‘going dark’

Congress has failed to pass a three-week extension of Section 702 of the Foreign Intelligence Surveillance Act (FISA), with the House voting 218-198 against reauthorizing the controversial warrantless wiretapping authority through July 2nd. After a short-term extension earlier this year, the spying program now appears set to lapse for at least a week. This is the nightmare scenario FISA’s proponents have been warning about — but it doesn’t actually mean the US has lost its surveillance capabilities.

Proponents of a clean extension claim a lapse will hinder intelligence agencies’ efforts to thwart potential terrorist attacks, with surveillance networks “going dark”. Sen. Tom Cotton (R-AR) stressed the importance of reauthorizing Section 702 ahead of the World Cup. House Speaker Mike Johnson (R-LA) has said even a brief lapse would be disastrous. “Democrats in the Senate are playing political games right now with the lives of Americans,” he told reporters Wednesday. “It’s a very dangerous situation.”

In March, the FISA court recertified surveillance under Section 702 until 2027. The Brennan Center for Justice notes that a lapse won’t allow telecom companies to flout requests to hand over communications information to the NSA and other spy agencies. In 2008, after Yahoo failed to comply with a Section 702 request during a lapse, the FISA court ruled that the directives issued under Section 702 are effective while the certification is in place — even in the event of a lapse.

“The phrase ‘going dark’ is significantly misleading,” Andrea Sawka Fiegl, the senior policy director for media and technology at Common Cause, said on a Tuesday press call. Fiegl added that companies don’t choose whether they participate in surveillance under Section 702. If they don’t comply after being served with a directive, they face fines starting at $250,000 a day.

“The ‘going dark’ framing is basically a pressure tactic designed to strip Congress of its leverage to negotiate reforms by creating this false binary,” Fiegl said. “There is ample time for Congress to consider and pass reforms.”

Among those reforms are a warrant requirement for queries involving US persons, including so-called “backdoor searches” in which intelligence agencies identify a foreign target with ties to a US person, and then search that person’s communications, thus granting them access to their desired US target. Reformers also want to prohibit intelligence agencies from buying Americans’ data from private brokers to get around warrant requirements.

“Every day that Section 702 is in effect without reforms is a day that Americans’ rights are under threat,” Sen. Ron Wyden (D-OR) said in a statement Wednesday night, after Senate Republicans blocked his request for a five-week extension of Section 702 with new transparency requirements. “If there is going to be an extension of these authorities, there needs to be some guardrails or at least some transparency that would allow Congress and the American people to understand the abuses that have taken place and the need for reforms.”

Though President Donald Trump and Republican leaders in both chambers have called for a clean reauthorization of Section 702, there’s bipartisan appetite for reform — and a handful of Republican holdouts stand in the way of a clean reauthorization. Most Democrats — even some who have supported reauthorization in the past — have objected to a clean extension due to Trump’s appointment of Bill Pulte as acting director of national intelligence.
