Malicious email campaign purporting to be Subway delivers Trickbot malware
Malicious emails purporting to be from sandwich company Subway UK are being reported by multiple sources, including consumers and security researchers alike.
Yahoo has said that all of its 3 billion user accounts were affected in a hacking attack, which dates back to 2013.
The company said an investigation had shown the breach went much further than originally thought. The stolen data did not include passwords in clear text, payment card or bank account data, it added.
Previously the internet giant had said "more than one billion" of its accounts had been hit.
Yahoo said that while its latest announcement did not represent a new "security issue" it was sending emails to all the "additional affected user accounts".
The company added that it was "continuing to work closely with law enforcement".
TOP TIPS For Protecting Yourself
If you have been affected, change your password and security questions for your online accounts.
Use 3 random words to create a strong password. Numbers and symbols can still be used, however three random words is the key to creating a strong and memorable password.
Other Tips
- Monitor your account for any suspicious or unexpected activity.
- Be very wary of any emails purporting to come from Yahoo, particularly if they prompt you to click any links, download any attachments or give out any personal information.
- Be wary of anyone calling asking for personal information, bank details or passwords. If in doubt, just hang up.
- Watch out for signs of identity crime. Visit services such as Experian, Equifax or Noddle to check your credit rating to make sure no one has applied for credit in your name.
