Just seen this in the Guardian…
https://www.theguardian.com/technology/2025/jun/21/internet-users-advised-to-change-passwords-after-16bn-logins-exposed
“Internet users have been told to change their passwords and upgrade their digital security after researchers claimed to have revealed the scale of sensitive information – 16bn login records – potentially available to cybercriminals.
Researchers at Cybernews, an online tech publication, said they had found 30 datasets stuffed with credentials harvested from malicious software known as “infostealers” and leaks.
The researchers said the datasets were exposed “only briefly” but amounted to 16bn login records, with an unspecified number of overlapping records – meaning it is difficult to say definitively how many accounts or people have been exposed.”
I'm hopeless with this kind of stuff. Should we all change our passwords, if so, for absolutely everything (email, banking, shopping sites etc)? It would take me hours…
Unreasonable - probably no need to change
Not unreasonable - change… better safe than sorry
