How does this scam work?
Sam Mitrovic, a Microsoft solutions consultant, shared his experience of being targeted by an elaborate scam that preyed on Gmail users. He recounted how it all started with a seemingly innocent notification:
“Recently, I received a notification to approve a Gmail account recovery attempt. The request originated from the United States. I denied the request and, about 40 minutes later, received a missed call. The missed call showed the caller ID as Google Sydney.”
Sam shrugged off the missed call, but the pattern repeated exactly one week later. He received another Gmail account recovery notification from the U.S. followed again by a call. This time, he answered.
“It’s an American voice, very polite and professional. The number is Australian. He introduces himself and says that there is suspicious activity on my account. He asks if I’m travelling (sic). When I said no, he asks if I logged in from Germany to which I reply no. He says that someone has had access to my account for a week and that they have downloaded the account data. (I then get a flashback of the recovery notification a week before).”
Sam quickly Googled the phone number, and it appeared in Google’s official documentation. Still skeptical, he asked the caller to send an email for verification. When the email arrived, the sender seemed legitimate at first glance, coming from a Google domain. However, Sam noticed a red flag: The “To field” contained an email address named GoogleMail at InternalCaseTracking dot com. This address doesn’t belong to Google.
Upon doing research, Sam discovered that the person on the other end wasn’t human but AI. This approach is part of a well-known phishing methodology aimed at confirming account recovery or password resets. But when combined with AI calls and email spoofing, this scam becomes particularly dangerous.

How are scammers spoofing Google’s email address?
Mitrovic pointed out that scammers spoofed the sender’s email address to make it appear as if it were from Google. They utilized Salesforce CRM, a platform that enables users to customize the sender information to anything they choose while sending emails through Gmail and Google servers.
CyberGuy reached out to Google for a comment but did not receive a response by the time of publication.

5 ways to protect yourself from Gmail AI scam
1) Understanding Google’s automated support system: Google has billions of users, so contacting them regarding any issue requires significant resources. Everything is automated, and Google doesn’t call Gmail users unless they have a connected Google Business Profile.
2) Inspect email addresses carefully: Always check the email address carefully. In this case, the email included a recipient address that was not associated with a Google domain. Additionally, there were no other active sessions on the victim’s Google account besides his own.
3) Be cautious with links and attachments: Avoid clicking on links or downloading attachments from unknown or suspicious emails. Instead, navigate directly to the website by typing the URL into your browser.
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 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.
4) Enable two-factor authentication (2FA): Use 2FA on your accounts to add an extra layer of security. This requires a second form of verification, such as a text message or authentication app, making it harder for scammers to gain access even if they have your password.
5) Regularly monitor your accounts: Keep a close eye on your accounts for any unusual activity. Set up notifications for login attempts and changes to your account information. Early detection can prevent further damage.

Kurt’s key takeaway
While AI has some useful applications, it is more actively exploited by scammers to make their schemes more believable. The Gmail AI scam demonstrates how AI can make scams harder to detect, and anyone who isn’t careful may fall victim to these scams. Google should work on improving scam filters to ensure that these impersonation scams do not reach people’s mailboxes. You can also do your part by being cautious and avoiding unknown links.

This wildfire evacuation alert accidentally went out to everyone in LA
After two days of dealing with wildfires that have burned thousands of acres, residents across Los Angeles County received a wildfire evacuation alert on Thursday afternoon that was a mistake. Shortly after, officials sent a follow-up alert saying that the notice was intended only for people near the Kenneth Fire in Woodland Hills.
Los Angeles County shared a message on X explaining what happened: “An evacuation order for residents near the Kenneth Fire currently burning in West Hills was mistakenly issued Countywide. This alert was only intended for residents of Calabasas and Agoura Hills.”
CBS News quotes a local official who said that the alert, which included a broken URL, was sent “due to a technical error.”
Many wildfires are burning in the LA area, and officials have confirmed at least six deaths, CNN reports. LA County has a population of nearly 10 million people, which is the “largest population of any county in the nation,” according to the county’s website.

Solar device transforms used tires to help purify water so that it's drinkable
Imagine a world where clean drinking water is readily available even in the most remote areas.
This vision is becoming a reality thanks to innovative research from scientists in Canada.
A team of scientists at Dalhousie University in Halifax, Nova Scotia, has developed a groundbreaking device that could revolutionize water desalination, offering hope to millions facing water scarcity worldwide.
I’M GIVING AWAY THE LATEST & GREATEST AIRPODS PRO 2
The power of plasmonic solar stills
At the heart of this innovation is a floating solar still, a device that harnesses the sun’s energy to purify seawater.
Dr. Mita Dasog, an associate professor of chemistry and Killam Memorial chair at Dalhousie, explains the science behind it: “Refractory plasmonic nanomaterials are very good at capturing light and converting that light into heat.”
This principle forms the foundation of their ingenious design. The solar still, conceptualized by Dr. Matthew Margeson during his Ph.D. studies, addresses challenges that have long plagued similar devices. It minimizes thermal losses, prevents salt buildup and can withstand harsh maritime conditions.
A BREAKTHROUGH GADGET COULD HELP YOU DETECT MICROPLASTICS IN YOUR DRINKING WATER
How it works
The floating solar still operates through an elegantly simple yet highly effective process. First, ocean water is drawn up to the device’s foam surface through a wicking system. Once the water reaches the surface, it is evaporated by solar-heated plasmonic materials. As the water vapor rises, the salt is left behind, ensuring that only purified water is collected. The vapor then recondenses on a clear plastic dome situated above the device. Finally, the purified water is funneled down the sides of the dome and collected in a sealed bag for easy access.
The results of this process are impressive. In real-world tests conducted in Halifax Harbour, the device produced up to 0.97 gallons of clean water daily, which was a record-breaking yield for passive floating solar stills.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
AUTONOMOUS TRASH-GOBBLING ROBO BOAT WAGES WAR ON WATERWAY WASTE
Upcycling for sustainability
What sets this device apart is its use of unconventional materials. Instead of relying on expensive precious metals, the team turned to an unlikely source: used tires. Through a process called pyrolysis, carbon waste from tires is transformed into a crucial component of the desalination unit.
Dr. Dasog emphasizes the importance of accessibility: “We shouldn’t be making an expensive or very complicated device. It has to be easy to manufacture, last for a long time and be easy to take apart and move.” This approach not only makes the technology more affordable but also addresses the environmental issue of tire waste.

Affordable water purification and energy generation in one device
The device’s capabilities extend beyond water purification. It can simultaneously desalinate, disinfect and decontaminate water at a remarkably low cost: less than one cent per liter. It can also generate a small amount of thermoelectricity, potentially powering onboard water quality sensors.

Looking ahead
The team’s next step is to conduct further testing in South Asia, with the ultimate goal of making the device available worldwide. Dasog, nominated for the Emerging Leader award at the Water Canada Summit, envisions the device as a lifeline for communities displaced by war or climate change.
Kurt’s key takeaways
As we tackle the growing challenges of water security, innovations like the plasmonic solar still shine a light of hope. By blending cutting-edge science with sustainable materials, the researchers at Dalhousie University are doing more than just purifying water; they’re paving the way for a future that is both equitable and resourceful. This device not only makes clean drinking water accessible but also highlights how we can use renewable energy sources to address pressing global issues.
