Let's Encrypt discovers CAA bug, must revoke customer certificates

On Leap Day, Let's Encrypt announced that it had discovered a bug in its CAA (Certification Authority Authorization) code. The bug opens up a window of time in which a certificate might be issued even if a CAA record in that domain's DNS should prohibit it. As a result, Let's Encrypt is erring on the side of security and safety rather than convenience and revoking any currently issued certificates it can't be certain are legitimate. READ MORE...

Ransomware Attackers Use Your Cloud Backups Against You

Backups are one the most, if not the most, important defense against ransomware, but if not configured properly, attackers will use it against you. Recently the DoppelPaymer Ransomware operators published on their leak site the Admin user name and password for a non-paying victim's Veeam backup software. This was not meant to expose the information to others for further attacks but was used as a warning to the victim that the ransomware operators had full access to their network, including the backups.

Why 'free' Wi-Fi isn't really free

How much would you 'pay' for 'free' Wi-Fi? Would you give away your birthday? Your travel details? Your home address? Your phone number? Well, a couple of weeks ago, a security researcher in the UK was looking around online when he came across yet another company that had joined the 100 million club. That's the name we jokingly coined back in 2013 when Adobe infamously suffered a breach that exposed 150,000,000 encrypted password records in one go. READ MORE...
