Worthy Warnings

  • Earlier this year Twitter patched a vulnerability that allowed attackers to get the phone numbers and email addresses associated with accounts. The bug was quickly patched, but we didn’t know how much data has been stolen before the patch was applied – now we know that a collection of at least 4.5 million records is for sale on the dark web. There’s no way to know if you’re in the DB, so all Twitter users need to be wary of targeted phishing attackswww.macobserver.com/…

Notable News

  • Facebook have changed their URL scheme so as to replace human-readable tracking IDs in URLs with encrypted blobs, preventing privacy-conscious browsers from stripping the tracking IDs from links shared on social media etc. — tidbits.com/… (Editorial by Bart: this was unfortunately to be expected as more and more browsers started to strip tracking IDs out of URLs)
  • Having briefly reversed the rollout, Microsoft have moved forward for once and for all with the change to block VBA macros by default on documents downloaded from the web — nakedsecurity.sophos.com/…
  • Google have taken ChromeOSFlex out of bata with its first stable release, providing a mechanism to securely re-use old hardware no longer supported by supported versions of Windows or macOS — www.macobserver.com/…
