What happenedSecurity firm Hudson Rock reports a malware tool, Remus Stealer, that allegedly keeps access to Gmail after password changes and session revocation.
Who is affectedMainly businesses and high-profile people using Gmail, since the tool is sold to enterprise customers and needs an already compromised mailbox.
What to do
  1. 1Be wary of urgent emails, spelling mistakes and odd sender addresses.
  2. 2Double-check the sender's email address before you click anything.
  3. 3Run trusted antivirus software on your PC, Mac and Android phone.
  4. 4Watch for a Google response and any new Gmail protections.

A security firm says a hacking tool can keep reading a Gmail inbox even after the owner changes the password and signs out other devices. The tool is called Remus Stealer and reportedly rents for $1,000 a month. The claims are not proven. Tom's Guide has asked Google for comment and has not yet had a response.

Why it matters

Email is the key to many other accounts. If the claims are true, attackers could grab password reset links and verification codes. Hudson Rock says it spoke with the developer and a customer, who shared screenshots of messages, timestamps and controls for sharing a hacked mailbox with other operators.

What is not known

How it survives a reset is unclear. The developer gave no technical details, only saying the tool interacts with browser memory. Hudson Rock's leading guess is that it grabs reusable permission from a signed-in browser. A remote part could then keep requesting mail after the program on the computer closes.

Who can relax

The tool is advertised to enterprise buyers, so businesses and high-profile people are the likelier targets. The mailbox must also be compromised first. Most people face lower risk. The best defense is avoiding phishing and malware, which the alert box above covers. Watch for Google's response and any new Gmail protections.

The takeaway

Most people are at low risk, but stay alert to phishing and malware, since a stolen inbox can unlock your other accounts.
