Poor investigative and misleading journalism by the BBC. The threats found have long been mitigated. It's the fault of owners if their kit is vul. China trust is a different issue. BBC News - The tech flaw that lets hackers control surveillance cameras bbc.co.uk/news/technolog…
#Facebook fail again. Reported a clear credential harvesting scam to Failbook and they do nothing. Incredible 🤦
forbes.com/lists/most-cyb… This is boarding on incompetence by Forbes. Not only is there no such thing as the most cyber secure, after all it only takes one vul but I bet the security leaders of those companies are over the moon that they're in this target list. 🤦

The MOVEit Transfer exploitation is not just SQL injection(👀) We uncovered the very last stage of the attack chain to drop human2.aspx ultimately ends up gaining remote code execution ‼ We fully recreated the attack chain with a demo achieving a reverse shell & ransomware!
bleepingcomputer.com/news/security/… This is an interesting angle to the insider threat. </snip "revealed Liles' unauthorized access to private emails, pointing to his home's IP address." </snip Thank goodness he wasn't that smart for a Security Analyst I guess.

So much for incident sharing! Received fraudulent emails from a compromised business account and they showed absolutely no interest. 😡🤬
Tech became 'darker and more muddy' in 2018 due to data abuse says EU. Hypocrites, EU states surveillance laws data collection and continual push for crypto backdoors is far more “darker”. bbc.co.uk/news/technolog…
OMG! Renewing car insurance and they say loan lending sites are crooks! Insurance companies are criminal money extortion gangs that seem to have the law on their side.
