Criminals are still dominating the game, why are we doing so wrong, and what can we learn in this tech ocean ?

Alexandre Blanc CyberSecurity weekly cyber linkedin
Sept 2021, and criminals are still winning the game, despite all the cloud sparkles

Each week is a learning opportunity, we learn from incidents, we learn from vulnerabilities, we learn from others, and we learn while sharing. Yet, all claiming to have the silver bullet, and in reality, it’s just widely inapplicable to the reality of businesses.

The tech world is echoing so strongly its own stuff, that it doesn’t hear the market and businesses anymore. All sailing in a digital storm in a weak boat, trying to stay afloat, while pirates, whoever their sponsor are, are riding on jet-skis with extreme agility.

The cloud is like a big ship, offering for smaller ones (SMBs etc) to host their critical assets, but the cloud, is also a huge marketplace, and you have no idea about what happen to your assets in these big ships, but one thing is sure, the space is expensive, and loading or unloading your assets is very expensive and dangerous, not forgetting the pirates on their jet-skis jumping on any chunk they can catch or poison.

Can I stop here without thinking about phishing ? Nah, there is big phishing going on as well, this is an ocean after all ! Are you credentials (be them password, biometric, certificates or whatever serves as key, doesn’t matter, all the same) going to be served on the next dark web sushis plate ? (sorry if you are allergic to phish :P )

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

Alexandre Blanc CyberSecurity weekly cyber linkedin
Alexandre Blanc Weekly cyber, quite late this time, on a sunday night !

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 !

Before the sun chase the clouds and make this world beautiful again !

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.

4 – The cloud strikes again ! (I know you come from my cloud rants :P ) – MyRepublic Data Breach Raises Data-Protection Questions

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%

11 – You are hacked and you don’t know it yet – Linux Implementation of Cobalt Strike Beacon Targeting Organizations Worldwide

12 – Hopefully you’ll update your build quickly, but won’t drop security scans to avoid supply chain attacks – Critical Bug Reported in NPM Package With Millions of Downloads Weekly

13 – Do you have an incident response plan ? ( hint : you must have one) – BlackMatter ransomware hits medical technology giant Olympus

14 – A not so sandboxed browser tab (deception again I know) – New SpookJS Attack Bypasses Google Chrome’s Site Isolation Protection

15 – On a related topic, the not so #privacy focused browser needs patching – Google patches 10th Chrome zero-day exploited in the wild this year (Security and privacy are two very different things ! )

16 – Windows 11, lol – Firefox now bypasses Windows 11’s messy default browser settings (yet they are about to sign a deal with Microsoft to make Bing the default search engine….. that makes you wonder)

17 – Apple patch time ! There is a worm in the apple – Apple products vulnerable to FORCEDENTRY zero-day attack – patch now (if you haven’t patched at this time, shame on you ! )

18 – HP Omen patch time (HP Gaming PC line) – HP OMEN Gaming Hub flaw hits millions of gaming devices

19 – Always watch where you download from, as once again threat actor use ads to be placed on top of search results – New Stealthier ZLoader Variant Spreading Via Fake TeamViewer Download Ads . That said, using pihole instance as your DNS server should wipe all ads from your web browser, and drop the risk :P

20 – The evolution of ransomware, from early days to industrial infrastructure take over – Ransomware, a timeline of destruction Part II

21 – We often say the perimeter is gone, but it doesn’t mean your attack surface is gone, it’s actually expended and on steroid if you use the cloud – Principles Of External Attack Surface Protection: Discover Everything

22 – Top of the risks being the dangerous cloud and an ever growing uncontrolled attack surface. No wonder why data continuously leak – Most Fortune 500 companies’ external IT infrastructure considered at risk

23 – A very accurate view, explaining why it takes an incident for organization to handle their security posture properly – Ransomware preparedness is low despite executives’ concerns

24 – Don’t forget to register for the coming event on Sept 24th, great panels covering the ransomware challenges, and what we can do about it – I’m lucky to participate in 2 panels, with amazing co-panelists, and this will be quite fun and interesting – Was so sick during the preparation of this one, you have no idea :P

28 – You’d better be sure that the channel you pick as replacement for the password is as safe as the password ! Sensitive topic to me, I don’t think passwordless is a fix, password is supposed to be a secret, if no longer a secret, then there is no confidentiality, see what I mean ? If you need third party to support the validation of you, this is becoming to be complex – Microsoft rolls out passwordless login for all Microsoft accounts (lots of comments on this post, some pros, some cons).

40 – I have to admit, it has been couple of weeks since the last joke like this – New Windows security updates break network printing

41 – How much would it take to bribe your low paid employees for their access ? AT&T lost $200M in seven years to illegal phone unlocking scheme

42 – As usual, keep your systems patched, and apply one of the oldest security principle, least privileges. Nowadays in an hyper connected and infected cyber world, it would not be very wise, to say the least, to let any user with full power on a systems, or even not patching properly – Capoae Malware Attacking Linux systems & Web Apps Using Multiple Vulnerabilities

raspberry 3 – routeur pare feu point d’acces wifi avec filtrage pub et tracking – router firewall access point with ads and tracking filtering

Liens mis a jour le 9 Novembre 2018 (version 8GB avec firewall sur ethernet et prise en charge du LAN sur USB, explications dans rc.local) – Links updated on 2018 Nov 9  ( 8GB version with firewall on ethernet port and LAN connectivity on USB adapter)

FAQ and more : http://blog.inforeseau.com/raspberry-3-router-project-faq

English below french.

Celui ci va être Français anglais (Compter 1h30 au total : 15min pour telecharger le fichier, 30 min pour extraire le .img du bz2, 30 min pour flasher la carte avec etcher) – routeur, firewall, filtre a publicite et tracage, point d’acces wifi and LAN (raspberry pi 3 + adaptateur USB cable matters pour le LAN)
This one will be in french and english (Count 1h30 total : 15min to download the file, 30 min to extract the .img file from bz2 archive, 30 min to flash the card with etcher) – router, firewall, ads filtering, tracking blocker, wifi access point and LAN (raspberry pi 3 + USB LAN adapters from cable matters)

Étant très sensible a la vie privée, et ne supportant pas les mensonges permanents du marketing, j’avais mis en place une instance « Pi-Hole » sur mon routeur maison, qui s’est avérée très efficace, voir indispensable.
Mais, pour des personnes moins techniques, la mise en place peut etre un peu complexe (meme juste changer les DNS dans un routeur), alors23 j’ai décidé de préparer une solution plus facile a mettre en place, et peu invasive.

J’ai préparé une image pour raspberry 3 (Micro SD 8GB – mais je recommande une taille supérieure, selon le modèle, l’image va refuser de restaurer pour cause de carte trop petite) qui vient pre-configuree avec raspbian + create_ap + pi-hole + listes de blockage en plus + mise a jour automatique des listes noire + gestion d’un LAN via adaptateur USB,  disponible ici : https://owncloud.mayahtt.com/index.php/s/fA2j57KcrzsFN29
Voici un lien alternatif sur google drive, potentiellement plus rapide : https://drive.google.com/open?id=1ATRAB7kXEHxMxlo-ER-eNrl_Hc8D-3yv
md5sum de l’image est : 3dcb8679db2cdb905a789c8768d78ae5

Action a suivre :
– Acheter un kit raspberry3 modèle B (comme ici https://www.newegg.ca/Product/Product.aspx?Item=N82E16813300009&cm_re=raspberry_pi_3-_-13-300-009-_-Product ou sur amazon https://www.amazon.ca/LANDZO-Raspberry-Completed-Kits/dp/B01IOVOQ38/ref=sr_1_14?ie=UTF8&qid=1529416642&sr=8-14&keywords=raspberry+pi+3+starter+kit – si le lien expire, chercher un raspberry starter kit) Il faut une carte micro SD > 16GB pour restaurer l’image (8GO est le format que j’utilise, mais certaines cartes sont legerement plus petites et ne permettent pas de restaurer simplement, c’est plus sur de prendre plus gros, meme si le systeme ne consomme que 2.5GB)
– Acheter cet adaptateur cable matters si vous souhaitez brancher votre LAN (reseau local) pour un usage comme routeur : https://www.amazon.ca/gp/product/B00BBD7NFU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
– downloader l’image (ici ou la ) que l’on met sur la carte avec etcher (disponible ici https://etcher.io/ )
Note : décompresser le fichier bz2 pour l’utiliser avec etcher (bunzip2 sous linux, ou 7zip sous windows)
– optionnel : éditer les paramètres dans rc.local (idéalement, comme c’est un système de fichier linux ext4, il faut monter la carte sur une machine linux, ou ajouter le support ext4 pour windows), et changer les valeurs « wifissid » et « wifipass » (sous rootfs/etc/rc.local)
– mettre la carte dans le raspberry, le brancher sur votre réseau maison (ou modem, car il y a maintenant un firewall sur le port ethernet), et hop, un nouveau point d’accès wifi, qui gère son propre réseau, avec filtrage pi-hole, est disponible. Si utilisation comme routeur : Le port reseau du raspberry est le port « WAN » (brancher internet dessus, le modem ou access internet en RJ45), tout peut sortir, rien ne peut entrer. Le pors USB est le port « LAN », a utiliser pour le reseau interne (vos PCs etc. Brancher directement un PC ou par un switch).

– SSID par defaut : raspappriv

– password par defaut : welcomepriv2

J’espère que vous aimerez ce petit outil (le mot de passe par défaut « welcomepriv2 » est également le mot de passe du compte « pi » accessible en ssh pour ceux qui veulent jouer.
En se connectant en wifi a ce réseau, on obtient des adresses en 192.168.12.x sur le wifi, et en 192.168.13.x sur le LAN USB, et l’interface d’admin du pi-hole est joignable sur http://192.168.12.1/admin.

“Pi-hole® est une marque déposée de Pi-hole LLC”
En utilisant l’image fournie, vous décidez de le faire a vos propres risque. Bien que je n’ai utilisé que les sources libres citée ci dessous, si un défaut ou tout autre problème survenait, je ne pourrais être tenu pour responsable (décharge de toute responsabilité ici).
Il vous incombe de mettre a jour le système pour corriger les problèmes de sécurité qui pourraient apparaître (comme la mise a jour des firmware de votre routeur etc).
Liste des composants utilises :
Rasbpian de raspberry.org : https://www.raspberrypi.org/downloads/raspbian/
create_ap : https://github.com/oblique/create_ap
Pi-hole : https://pi-hole.net/

#############
Since i’m privacy oriented person, and i can’t stand permanent marketing lies, i had setup a « pi-hole » on my home router,which became so efficient that i can’t browse without it.
But, for less technical persons, the setup might look a bit complex (even changing the DNS in your router can be), so i decided to preapre an easy to deploy solution, not invasive.

I made an image for raspberry3  (Micro SD 8GB – but i do recommend a bigger one, since sometimes the restore will state the target is too small to fit the image) which comes pre configured with raspbian + create_ap + pi-hole + additional ad blocking list + auto blacklist updates + LAN management via USB ethernet adapter , available here : https://owncloud.mayahtt.com/index.php/s/fA2j57KcrzsFN29
Here is an alternative download link from google drive potentially faster : https://drive.google.com/open?id=1ATRAB7kXEHxMxlo-ER-eNrl_Hc8D-3yv
md5sum of the image should be : 3dcb8679db2cdb905a789c8768d78ae5

Actions to take :
– buy a raspberry 3 model B kit (like this one  https://www.newegg.ca/Product/Product.aspx?Item=N82E16813300009&cm_re=raspberry_pi_3-_-13-300-009-_-Product  or on amazon https://www.amazon.ca/LANDZO-Raspberry-Completed-Kits/dp/B01IOVOQ38/ref=sr_1_14?ie=UTF8&qid=1529416642&sr=8-14&keywords=raspberry+pi+3+starter+kit  if the link expire, look for raspberry 3 starter kit) You’ll need a micro SD 16GB to restore the image (8GB is the format i use to create the image, BUT some manufacturer produce slightly smaller size which would not allow the image to restore properly, so you should get a bigger one to be on the safe side even if the system only use about 2.5 GB in the end).
– buy this USB Ethernet adapter from « cable matters » if you want the device to be your LAN router as well :  https://www.amazon.ca/gp/product/B00BBD7NFU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
– download the image (here or there) and you place it on the SD card with etcher (available here https://etcher.io/ )
Note : extract the bz2 image file to use with etcher (bunzip2 under linux, or 7zip under windows)
– Optional : tweak the settings in rc.local (ideally, since this is an ext4 linux based file system, you should mount the card on a GNU/Linux machine, or add ext4 support on windows), and then change the values of « wifissid » and « wifipass » (under rootfs/etc/rc.local)
– place the card in the raspberry, plug it on your personal network (or on modem, since ethernet port now has firewall enabled), and you have a new wifi access point that managed its own subnet, with pi-hole filtering.
– If you plan to use it as your main router, the onboard ethernet port is the WAN (to be connected to internet via modem or direct connection RJ45), all output is allowed, all incoming denied. The USB port to be used as LAN port, to connect your local devices (PCs, etc, use a switch to connect more).

– Default SSID : raspappriv

– Default password : welcomepriv2

I hope you’ll enjoy this little project. (the default password is « welcomepriv2 » which is also the password for the account « pi » reachable by SSH for anyone who wants to play.
When you connect to this network on wifi, you’ll get an IP in the 192.168.12.x range, and the pi-hole admin interface is reachble at http://192.168.12.1/admin.
You’ll get IPs on the range 192.168.13.x if you connect to the USB Ethernet LAN connection. BOTH internat networks can see each other and communicate.

“Pi-hole® is a registered trademark of Pi-hole LLC”
By using the provided image, you decide to use it at your own risks.
While i used the free/open-source resources listed below, if anything wrong would come to happen, i could not be liable to this.
It is up to you to update the system to keep it safe from security vulnerabilities than may appear in time (pretty much like it is your duty to update your router firmware)
