Riding cloud can be tricky, don’t fall from it, in the weekly cyber !

Somehow short week for me, but quite intense, ended escaping in the hoods off grid, and that’s pretty good !

Meanwhile, earlier, this week has been quite intense, and despite my good will, humanity always find way to show how bad and nasty it can be, and as bad as I want to expose stupidity, it will not help, because it seems some are so bad, that there is no cure. For these, R.I.P means Rot In Peace :D

BUT FOR YOU, 48K+ followers, 24K+ subscribers to this newsletter, I send you all my love, and the peace I found in nature, here, north from Quebec in the « Parc des Grands Jardins », where you wake after a cold night in beautifully frozen nature, that quickly transform as the sun rises !

Back to our topic, this week in 46 points, this happened :

1 – Scammers strategy reviewed, as they use porn scam to get your attention – Porn Spam, Malware and Questionable References to Teens

2 – I told you, they just went on vacation ! And now they are fully back ! REvil ransomware is back in full attack mode and leaking data

3 – Some said it’s great, I believe, in the case of this Facebook based service, a backup encrypted with a password stored in the cloud, is not something safe, how long will this backup hold against dictionary attack based on all the passwords ever leaked on internet ? 10 seconds ? WhatsApp to Finally Let Users Encrypt Their Chat Backups in the Cloud , good idea, but I’m afraid it’s a false sense of privacy.

5 – This article bring facts you must be aware of so as you avoid the pitfalls – cloud-based issues comprise 79% of observed exposures compared with 21% for on-premises assets ( I see you cloud lover, bla bla, this sentence is out of context, bla bla… ok, read the linked article on the post, and you’ll have all the context :) )

6 – Wireless is weak, bluetooth hacked again – BrakTooth Vulnerabilities Riddle Bluetooth Devices From Numerous Vendors

7 – Zero day exploit out and shared. No patch, no fix. Windows MSHTML zero-day exploits shared on hacking forums (more in the comments of the post as usual)

8 – How much do you know who’s really behind the keyboard ? Real-Time Identity Protection at Last: Closing a Critical Gap in our Security Stacks

9 – Once again, don’t fall for the scam – FTC warns of extortionists targeting LGBTQ+ community on dating apps

10 – Everything is fake in technology, and it’s very challenging to know what is a good investment and what is not (like if it took human model ! ). Fake Walmart press release hoax causes Litecoin to spike 34%
