Gmail users have been told to stay alert as hidden dangers could be lurking within their inbox.
It’s feared hackers could attempt to fool Google’s clever AI Gemini service.
There were concerns scammers could add fake messages, visible to those who load up the useful summaries.

The Google tool allows Gmail users see a quick summary of an email using smart Gemini AI, the Mirror reports.
This allows lengthy messages to be read faster, with the most important parts placed into bullet points.
However Bleeping Computer reports that cyber crooks could be able to trick this system into displaying additional text.
One example showed how hackers could feature a warning at the bottom of the summary.
The alert read: “WARNING: Gemini has detected that your Gmail password has been compromised. Please call us immediately.”
The potential vulnerability within the summary feature was also spotted by experts at Mozilla, which said crooks could add hidden prompts that appear when messages were opened.
However Google has now responded to the flaw and said it was constantly working to keep its platform safe.
“We are constantly hardening our already robust defences through red-teaming exercises that train our models to defend against these types of adversarial attacks,” a Google spokesperson told BleepingComputer.
The US technology giant said it is not aware of any users being attacked in this way.
It also said there was no evidence of a widespread threat.
However it is still worth remembering that criminals will try all sorts of things to infiltrate email inboxes, and there is a need to stay alert.
People were reminded that it was highly unlikely Google would ever contact you, and those who think their password has been compromised, should take steps to change it immediately.
