Hackers are posing as crypto investors via Calendly
The way this particular threat works is rather straightforward, yet sneaky. To start, many people in the crypto world are seeking investments to support their crypto start-up ideas or something related.
People like this need to be active in crypto communities and investment spaces to connect with the right people to support them. It’s not uncommon for these people to have a link to schedule a meeting with them on their profile, via Calendly, a popular scheduling app not just for people in cryptocurrency but for anyone.

How the hacker infiltrates the target’s device
Unbeknownst to the soon-to-be victim, these hackers are taking advantage of these individuals by posing as crypto investors, the exact kind of people these folks want to get in touch with. When they book a meeting on this person’s calendar, they add a meeting link that runs a script that installs malware on macOS systems.
A real-life example of how crypto impersonators lure victims
This happened to one unlucky person in this situation. The hacker reached out via Telegram – an encrypted messaging app – and asked about booking a meeting. The person sent the “investor” their Calendly link, and on the day of the meeting, went to the meeting link that the “investor” had added. In most cases, this is normal – a link to a Zoom or Google Meet is not unusual. And because the user had already spoken to the person via Telegram and seemed legitimate, there was no reason to think twice about this.
The sinister scheme was revealed when links failed
Only when the person went to click the link and when the “investor” didn’t show up, did he contact him on the same Telegram thread. The “investor” apologized for the inconvenience and sent a new link, explaining there was an issue with IT.
However, the link still did not work, and the meeting never happened, with the “investor” asking to reschedule. It dawned on the person a little afterward that this may have been a hack attack, via an Apple Script (file extension “.scpt”) that downloads and executes a malicious Trojan made to run on macOS systems.

How quick action foiled a Mac malware attack
Because the person who was the target of this attack promptly backed up their data upon realizing the attack, it prevented the loss of evidence regarding the actual malware downloaded onto their macOS. Cybersecurity firms were able to analyze the script information, which led them to identify similarities with previous attacks carried out by the same group and warn the public.

The perpetrators are a hacker group from North Korea
A cybersecurity firm discovered a phishing attack in 2023 that was carried out by state-sponsored hackers from North Korea, specifically a subgroup of the notorious Lazarus group. This group typically targets financial gains, aiming to steal money or cryptocurrency to fund the North Korean military regime.
In this particular attack, the North Korean hackers exploited the “Add Custom Link” feature within the Calendly meeting scheduling system on event pages to insert malicious links and initiate phishing attacks. They also employ similar tactics on Telegram.
This incident underscores the importance of vigilance and robust security measures to safeguard against cyberthreats, especially those originating from state-sponsored actors.

Calendly’s response to malware attacks
We reached out to Calendly, and their CISO (chief information security officer), Frank Russo, provided us with this statement.
“We’re aware of these types of social engineering attacks by cryptocurrency hackers. This attack violates our Terms of Use, and accounts are immediately terminated when discovered or reported. To help prevent these kinds of attacks, our security team and partners have implemented a service to automatically detect fraud and impersonations that could lead to social engineering. We are also actively scanning content for all our customers to catch these types of malicious links and to prevent hackers earlier on. Additionally, we intend to add an interstitial page warning users before they’re redirected away from Calendly to other websites.”
How to protect yourself against cyberthreats
MacOS users tend to experience fewer malware attacks than PC users. But this idea can make MacOS users more vulnerable to attacks because they may feel they are simply safe. Because hackers are getting more and more sophisticated, it’s important never to let your guard down and to follow these precautions.
Be cautious with links: If you receive a Calendly link from an unfamiliar sender, refrain from clicking on any embedded links, even if the sender appears trustworthy. Additionally, exercise vigilance when dealing with phishing emails or messages related to crypto exchanges or wallets, as they may contain malicious attachments or links with malware. When using Calendly, take note of the source and domain of any links you encounter on the interface. Before clicking, hover your mouse over the text to verify the link address and avoid accessing potentially harmful phishing links.
Send meeting links yourself: Whenever possible, send the meeting link directly to the person scheduling the call. This minimizes the risk of accidentally clicking on malicious links.
Have good antivirus software: The best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Mac, Windows, Android & iOS devices.
Perform regular updates: Regularly update your operating system and security software to stay ahead of potential vulnerabilities.
Have strong passwords and use two-factor authentication: Using the same password across multiple platforms will always make you more vulnerable because if one account gets hacked, they all get hacked. And two-factor authentication is just an extra shield that will prevent a hacker from getting into your accounts. Make sure to use a password manager to keep track of all your passwords.

Though Tim Cook is shedding his CEO title for the role of Apple’s executive chairman, it appears he’ll keep one of his most important duties: that of the company’s Trump whisperer.
“As executive chairman, Cook will assist with certain aspects of the company, including engaging with policymakers around the world,” Apple writes in a press release. Translation: he’s sticking around to deal with thorny political relationships — in particular the one with President Donald Trump.
Throughout his tenure, Cook has navigated Apple through tricky political terrain. He’s had to balance the company’s massive business interest in China with US policymakers’ concerns, and he’s worked to appease Trump for favorable regulatory decisions, without alienating too many Apple employees and customers in the process.
Cook has navigated Apple through tricky political terrain
The task of wooing Trump has repeatedly placed Cook in embarrassing situations: Cook showed the president around a factory in Texas in 2019, where Trump wrongly boasted that because of his policies, Apple was building a new manufacturing plant in the US. Last year, he presented Trump with a symbolic gift of “Made in the USA” glass from Apple supplier Corning set in 24-karat gold.
Recently, Cook took criticism from Trump critics for attending a movie night at the White House, for a screening of the documentary Melania, the same day that Alex Pretti was killed by federal agents on the streets of Minneapolis during a protest against Immigration and Customs Enforcement. Cook later vaguely referred to the “events in Minneapolis,” and referenced a “good conversation with the president.”
As Apple’s senior vice president of hardware engineering John Ternus takes over as CEO, the company will need to overcome significant policy challenges, including global efforts to regulate AI, and a push for app stores to verify user ages. Lucky for Ternus, Cook will still be there to take on that job.

Just about every day, we receive emails from readers who have encountered new scams. Many involve cryptocurrency. The pattern keeps repeating. Someone receives a message that feels urgent, emotional or exciting. The person on the other end sounds confident and persuasive. Before long, the victim is being asked to send money through cryptocurrency. Once the money is sent, it often disappears forever.
Cryptocurrency appeals to scammers for a simple reason. Transactions move quickly, often cross international borders and usually cannot be reversed once completed. That combination makes crypto payments especially attractive to criminals.
Kate recently wrote to us with a great question.
“Could you do an article that illustrates the scripts used by scammers to lure people to send money using cryptocurrency. Those scripts must be very convincing to get so many reasonably intelligent people to send money. Maybe five or six examples of the scripts, so people, especially seniors, will know what to watch out for.”
Kate is absolutely right. These scripts are convincing because scammers practice them constantly. They use psychology, urgency and emotion to push people toward quick decisions.

Let’s break down some of the most common crypto scam scripts, so you know what they sound like before they reach your inbox or phone.

The investment opportunity script
This script often begins with a friendly introduction through social media, email or even a text message.
Example script:
“Hi, I work with a private investment group that trades cryptocurrency. We’ve helped many people earn steady returns. If you invest $500 today, you could earn $5,000 within weeks. I can show you proof of other investors’ success.”
The scammer may send fake screenshots of profits. Some will even allow a small withdrawal early on to build trust. Eventually, they push the victim to send larger deposits. Once the larger transfer is sent, the account suddenly stops responding.
The romance crypto script
This scam often starts with a simple message on a dating app, Facebook or Instagram. The first contact is friendly and low-pressure.
Example initial script:
“Hi, insert name here, I hope you don’t mind me saying hello. Your profile caught my attention, and you seem like a very kind person. How has your day been?”
After a few days of conversation, the scammer begins sharing details about their life. They often claim to work overseas as an engineer, doctor or business owner. Eventually, they mention cryptocurrency trading as something they do on the side.
Later message in the script:
“I have been doing some short-term crypto trading after work. It has helped me save a lot faster. If you are interested, I can show you the platform I use. It is very easy to start with a small amount.”
From there, the scammer guides the victim to a fake trading site or asks them to transfer cryptocurrency to a wallet they control. At first, the account may show fake profits. The victim believes the investment is working and sends more money. Eventually, the victim cannot withdraw any money.

The government impersonation script
Scammers often pretend to represent government agencies or law enforcement.
Example script:
“This is an urgent notice regarding your tax account. Your Social Security number has been linked to suspicious activity. To prevent legal action, you must verify your identity and pay the outstanding balance today using cryptocurrency.”
Government agencies do not demand payment through cryptocurrency. The goal is to scare you into acting quickly without checking the facts.
The tech support emergency script
This scam often begins with a pop-up warning or an unexpected phone call.
Example script:
“Your computer has been compromised by hackers. Your bank information may be at risk. To secure your system, we need you to transfer funds temporarily into a protected cryptocurrency wallet.“
The scammer claims the funds will be returned once the system is secure. In reality, the transfer moves the money directly to the criminal.
The crypto giveaway script
This scam frequently appears on social media or video platforms.
Example script:
“We are celebrating a new crypto launch. Send 0.1 Bitcoin to this wallet, and we will immediately send back double the amount.”
The message may appear to come from a well-known company or public figure. The wallet address belongs to the scammer. Anyone who sends funds receives nothing in return.
The fake recovery service script
This scam targets people who have already lost money.
Example script:
“We specialize in recovering stolen cryptocurrency. Our investigators located the wallet that received your funds. To begin the recovery process, we require a small crypto payment to unlock the legal tracing tools.”
The victim believes they are hiring professionals to recover their money. Instead, they are being scammed again.
Why these scripts work so well
These scams succeed because they exploit human behavior. First, they create urgency. Victims feel pressured to act quickly.
Second, they create trust. The scammer may sound friendly or sympathetic.
Third, they promise rewards. Investment scams offer profits that feel life-changing.
Finally, cryptocurrency adds confusion. Many people are still learning how it works. Criminals take advantage of that uncertainty.
Understanding these scripts is the first step to protecting yourself. Once you recognize the patterns scammers use, it becomes much easier to stop the conversation before money is involved.
How to protect yourself from crypto scams
Crypto scammers rely on urgency, trust and confusion to pressure victims into sending money. These practical steps can help you recognize warning signs and avoid costly mistakes.

1) Slow down when money is involved
Scammers depend on urgency to push victims into fast decisions. If someone pressures you to send money immediately, treat it as a warning sign. Pause the conversation and verify the situation independently. Contact the company, agency or person through a known phone number or official website. Taking even a few minutes to step back can stop a scam before money leaves your account.
2) Never send cryptocurrency to someone you do not know
Cryptocurrency transactions work very differently from credit cards or bank transfers. Once funds are sent, they usually cannot be reversed. Scammers prefer crypto because it moves quickly and often crosses international borders. If someone asks for payment through Bitcoin, Ethereum or another digital currency, assume the request is suspicious until proven otherwise.
3) Verify investment opportunities independently
Many crypto scams promise fast profits or guaranteed returns. Legitimate investments never guarantee profits. Before investing, search the company name, website and contact information online. Look for warnings from regulators or consumer protection agencies. If you cannot find reliable information about the company, that is a major red flag.
4) Use strong antivirus software on your devices
Scammers frequently use phishing links, fake websites and malicious downloads to trick victims. Strong antivirus software can help detect these threats before they cause damage. Strong antivirus software can warn you about suspicious websites, block malicious downloads and help stop phishing attempts that try to steal your financial information. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.
5) Reduce the personal information scammers can find online
Scammers often research their targets before sending messages. They may gather details from public records, social media or data broker websites. Limiting the amount of personal information available online can make it harder for criminals to craft convincing messages. Removing your data from people search sites with a data removal service can reduce the chances of becoming a target. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.
6) Be cautious with online relationships
Romance scams often begin with friendly messages on dating apps or social media. Over time, the scammer builds trust and eventually introduces a crypto investment opportunity. If someone you have never met begins discussing cryptocurrency investments or asks you to move money, take a step back. Real relationships do not require financial transfers to strangers.
7) Never trust screenshots or profit dashboards
Crypto scammers often show screenshots of trading accounts that appear to generate large profits. These images are easy to fake or are displayed on fraudulent websites controlled by the scammer. Even if a platform shows profits, it does not mean the money exists. If you cannot withdraw funds easily through a verified exchange, the investment may be fake.
8) Watch for requests to move conversations off the platform
Many scams begin on social media, dating apps or messaging platforms. After the first contact, scammers often ask victims to continue the conversation on WhatsApp, Telegram or another private messaging app. Moving the conversation helps them avoid detection by the original platform. If someone quickly asks you to switch apps, treat it as a warning sign.
9) Talk to someone you trust before sending money
Scammers often isolate their victims and discourage them from discussing the situation with friends or family. Before sending cryptocurrency or making a large investment, pause and talk to someone you trust. A second opinion can often spot warning signs that are easy to miss when emotions are involved.
What to do if you already sent cryptocurrency to a scammer
If you believe you sent cryptocurrency to a scammer, act quickly. Contact the exchange or platform you used to send the funds and report the transaction immediately. Some exchanges may be able to flag the receiving wallet and help investigators track suspicious activity.
You should also report the scam to the FTC at reportfraud.ftc.gov and notify your local law enforcement agency. If the scam began on a social media site, dating app or messaging platform, report the account there as well so it can be investigated and removed.
While recovering funds can be difficult, reporting the incident can help authorities identify larger fraud networks and potentially prevent others from becoming victims.
Kurt’s key takeaways
Cryptocurrency scams continue to grow because the scripts are polished and carefully tested. The criminals behind them understand human psychology. They know when to apply pressure, when to build trust and when to promise rewards. Recognizing these patterns is one of the most powerful ways to stop them. When you know the script, the scam becomes much easier to spot.
Have you ever received a message that tried to convince you to send cryptocurrency, and did the script almost sound believable? Let us know by writing to us at Cyberguy.com.

As if there weren’t already enough devices listening in on everything being said in your home, Prego, the pasta and pizza sauce brand, is releasing a device designed to record everything said around the dinner table for posterity. The Connection Keeper, which looks like an oversized pasta jar lid, was created in collaboration with StoryCorps, the nonprofit organization focused on preserving the stories of Americans in a collection housed at the Library of Congress’ American Folklife Center. There’s no AI, Wi-Fi, or Bluetooth, but you can optionally upload recordings to StoryCorps’ website to make them easier to share with family.
Prego says the goal of the device is to encourage families to make memories through conversation during dinner instead of staring at their phones — but only for a small number of families. The company is only planning to make less than 100 of them. The Connection Keeper will be available for purchase online starting on April 27th for $20 as part of a bundle that includes the device, a jar of Prego sauce, spaghetti noodles, and a deck of cards featuring conversation prompts and ideas.
Using the device is as easy as plopping the Connection Keeper down in the middle of everyone at the table and pressing one button to start recording. Using a pair of microphones, it captures CD-quality audio to a 16GB microSD card for up to eight hours when fully charged.
When dinner’s over, the recordings can be transferred to a computer over USB-C and then uploaded to a dedicated microsite created by StoryCorps where they’re preserved and accessible only by the uploader, unless they choose to share them with other StoryCorps users or the general public. You even have the option to archive them within the Library of Congress, which makes them public automatically, so hopefully your family talks about more than just stealing brainrots.
The recordings can be accessed on a smartphone through the StoryCorps app, but Prego intentionally left phones out of the rest of the process to discourage their use at the table. It’s also why the Connection Keeper lacks a screen. The goal was to minimize interactions with the device so family members instead focused on talking with each other.
