From a broken TLS CA, to Facebook, to FIN12 hit and run

Alexandre Blanc CyberSecurity weekly cyber linkedin
Alexandre Blanc Weekly Cyber

Yet another crazy week in cyber, which makes me wonder if there is any quiet week anymore, and, as a lot spoke about mental health as well, how long do you think a human can take all of this ?

Meanwhile, I’m still motivated to do good, and while ransomware gangs make millions every month, we try to get a couple of bucks from people so as we can help secure them (not asking for money, just tough to get organization to spend just enough to protect themselves).

But I’m telling you, this won’t last, ransomware projections are so huge, that we’ll come to a point where, sorry, we don’t take new customers. Scarcity, is where we’re heading, and I’m telling you, find your cyber security partner NOW, because we, skilled humans in this field, are in very limited supply. The illusion of the market may make you think you have choice, but there is a fun fact in the back end, A sells the skills of B, which sells the skills of C, which rely on A for any overflow…… do you see it coming ?


Monica talks Cyber to Alex

Meanwhile, Monica and myself are going to share some insights on our CISO experience, hopefully a series to start in November, and well scheduled (according to her, she likes when things are organized, and it’s good !), and pretty fun (according to me, and her actually, we agree on this)…. (wait, did I mean we don’t agree on everything ? )…. (seems I’m talking to myself now…. ok, let’s move on).

Edit : Monica said that I should say that the audience will have an AWESOME opportunity not only to ask ya questions for this episode but ALSO TO SHAPE OUR NEXT EPISODES and what challenges we address (that’s what she said :P )


Mani got Alex to talk and talk and talk :D

This week as well, did record a 6 min LinkedIn podcast with Mani Keerthi which actually turned to be very relevant in a pretty short time ! Thanks Mani ! :)


And now, finally, this week in 56 points :

1 – Letsencrypt updated their CA (certificate authority) and it went bad for a lot of stuffs – Let’s Encrypt’s root certificate has expired and stuff is breaking all over the place


2 – Surprise, yet another massive leak – US retailer Neiman Marcus confirms Data breach – Just 4.6 Millions customers data


3 – You first need to have proper security posture, otherwise, nothing will help you – US unites 30 countries to disrupt global ransomware attacks


4 – I fixed the issue by dropping any phone call. Only accepting known persons over encrypted channels – FCC orders phone carriers to enforce unlawful robocall blocking


5 – Hacked down to hardware – Flaw in AMD Platform Security Processor Affects Millions of Computers


6 – Cryptoland never cease to amaze me – Crypto platform mistakenly gives $90M to users, asks for refund


7 – Just a reminder, building your security posture, assessing the potential impact and placing proper security controls to mitigate the risk is not optional, unless you absolutely don’t care – Sandhills online machinery markets shut down by ransomware attack


8 – That’s hacking ! The power of technical creativity ! Creating Wireless Signals with Ethernet Cable to Steal Data from Air-Gapped Systems


9 – Clowd style leak ! Poorly Configured Apache Airflow Instances Leak Credentials for Popular Services


10 – Like it or not, patch management is critical – New Atom Silo ransomware targets vulnerable Confluence servers


11 – Good work Europol, some less criminals – Ransomware operators behind hundreds of attacks arrested in Ukraine (doesn’t calm down anyhow, but that’s already something ! )


12 – Learn why privacy and data protection is important (aside of Pandora papers ) – Transnational fraud ring stole millions from Army members, veterans


13 – Quite an interesting take on this one, after all we are in a continuously evolving environment, seeing rising threats, and regulation playing ketchup – Regulations & Ransomware: A Quick Overview


14 – Facebook offline day ! Great for humans mental health, on this linkedin post, I covered, including comment, the whole story, with other, pointing to the BGP error , but we all know the truth : The home router of Mark got powered off as his cat stepped on it, and poof ! Facebook Blames Outage on Faulty Router Configuration


15 – Just don’t SMS, anything you type on it, is being reviewed by thousands of people, indexed, reshared and all – Company That Routes Billions of Text Messages Quietly Says It Was Hacked

27 – Take this as an example ! YOU must do it too on all your accounts – Google to turn on 2-factor authentication by default for 150 million users


28 – Good move, especially that investing less than the payment made to criminals is enough to build your whole security posture and strongly reduce the likelihood of such incident and totally squeeze the potential impact – Ransom Disclosure Act would give victims 48 hours to report payments


29 – Adam will never find a job in IT ever again – Fired IT admin revenge-hacks school by wiping data, changing passwords


30 – The Internet of threats (IoT) and the Industrial Internet of Threats (IIoT), must be sandboxed and protected behind layered defense and zero trust network access control – Multiple Critical Flaws Discovered in Honeywell Experion PKS and ACE Controllers

32 – The cloud leaks again, I think there might be a medication for this, I mean it can’t hold anything, anything it eats just is spread around…. looks like the cloud is sick to me.

52 – How would your organization detect and respond to such incident ?

What is your RTO ? Recovery Time Objective defines how long it will take for you to recover – Engineering giant Weir Group hit by ransomware attack


53 – Attribution is always a tricky game. Proxy, fork anyone ? But for sure, it’s easier to have visibility when you collect telemetry (backdoor) from most of the computers in the world ;) Microsoft: Russian state hackers behind 53% of attacks on US govt agencies
