The threat landscape is very dynamic – Cyber news this week

Alexandre Blanc CyberSecurity weekly cyber linkedin
The weekly worked very well on my blog, so I’ll stick with it for a while !

This week again has been quite loaded, and the technology environment, which define the attack surface, is only growing. It takes a vulnerability, a threat attached to it, and we have a risk.

To know the likelihood of any threat to be targeting our organization, we go through a threat modelling exercise. Sometimes it’s formal, documented and referred in the risk register, sometimes it’s a guesstimate, a rough high level assessment. Overall, better than not considering the risk at all.

This week in 49 points, hosted on my blog, because I know I won’t have limitations etc, and for each of these, there is something to learn, a security control you may have forgotten :

1 – The financial system is fully backed by technology, and therefore, fully vulnerable – World Economic Forum (WEF) Warns of Cyberattack Leading to Systemic Collapse of the Global Financial System – Do you have some cash handy ? You are your own risk manager, what happen if you can’t use your payment card for a week ? Do you have enough food ? Gas ? Just a week, think about it.

2 – Building and learning takes time, but if you don’t, you are not the real owner – This Best-Selling TP-Link Router Ships With An Alarming Security Surprise – Do you know what runs on your network ? and what or who is watching your online activities ? (aside of the ISP who gladly sell all your activity, including your favourite recipes on youcorn, they know if you like crunchy corn, or white corn, old corn or even big or slim corn ! yes a VPN might come handy, but think twice who should know how you like to eat your corn ! )

3 – I’m proud having received the Cyber Sentinel Award 2021 in India for my work in #cybersecurity, and that’s a huge news :P – Cyber Sentinel Award 2021 – In the post you’ll find link to the panel I had a chance to participate as well, you’ll see that trends in India are very aligned with trends in US and Canada !

4 – I told you to drill that weak NFC circuit on your payment card ! Paypass is unsafe – New Vulnerability Allow Hackers to Bypass PIN Codes on Contactless Cards From Mastercard & Maestro – Wireless is weak, you know the song

5 – Let’s clear something, when authorities come with a warrant, organizations must comply – Important clarifications regarding arrest of climate activist – unlike the cloud, they did not betray confidentiality, as they are not technically supposed to be able to access your encrypted mailbox, they could just tell which IP use this mailbox. VPN maybe ? again, know which VPN you use, deciding to give all your traffic to a VPN provider is something you should look twice.

6 – Transnational criminal organization are efficient businesses – “FudCo” Spam Empire Tied to Pakistani Software Firm – Enjoy the reading, understand how it works, and be sure there are thousands like these.

7 – bypassing MFA and password reset, more on the SAML golden ticket attack, an attack close to pass the hash – Golden SAML Attack – APT Hackers Hijacking & Gaining Access To The Active Directory Server – Attacker don’t even need your credentials to be logged as you, be aware, MFA + attribute based authentication with continuous diagnosis and mitigation, yes I speak about better than ZeroTrust, I speak about CGM !

8 – Do you really know who you are working for, and what’s the purpose of your work ? TrickBot gang developer arrested when trying to leave Korea – In the not so recent past, I worked for an organization which turned to be terrorists, and this is one of the way I learned how privacy matters, how it’s heavily tight to freedom. So, always check who you work for, and make sure you are sure this is what it is. It doesn’t only happen to others. Due diligence is a good practice for your daily life too.

9 – WordPress plugin patch time ! Gutenberg Template Library Plugin Bugs Affected 1+ Million WordPress Sites – Oh myyyy penguiiiiiinnnn ! I’m currently typing on WordPress ! Oh no ! I’m doomed, nooooooo !…. oh wait, I just clicked on « update » and in 10 sec my blog was updated…. and actually there is a worst one that this one, so you full WordPress deserves an update if you did not apply it today.

10 – Netgear patch time ! Netgear fixes severe security bugs in over a dozen smart switches – Yes, patching is a non stop job, you should have someone coordinating this in your organization, because patching a switch, will turn the network off for a few seconds, even minutes. Coordination is key !

11 – IoT, or the internet of threats, is only growing (it’s supposed to mean the Internet of Things, but it’s not accurate) – IoT Attacks Skyrocket, Doubling in 6 Months – And this is only growing, the more you connect, the more you grow your attack surface, and the need for security controls, network segmentation and more, I know, at home it’s not easy !

12 – Speaking about IoT, Don’t connect all this crap ! Vulnerabilities In Victure Baby Monitor Allow Access To Camera Feeds – Really need to watch your baby with Russia and China doing so with you ? Because they will, do you know this site « Insecam » ? Enjoy.

13 – What do you do when all your stuff is in the cloud and Internet is taken down by DDoS ? New Zealand suffers a widespread Internet outage – You can look at stuff like Cloudflare solutions, issue is, you must give away all your traffic to the platform, and while they claim they never tap any connection, this is still a risk to consider. Sometimes it’s also a matter of national security, you would not want to give all your national internet traffic to another country either. Not simple.

14 – CASB LOL ! Criminal access service brokers to the cloud – Enterprising criminals are selling direct access to cloud accounts – Did you setup geo fencing in your cloud configuration ? On your firewall it’s easy, you just allow only national IPs as per need, in the cloud you’ll pay per rule or so.

15 – Micro segmentation is the very first step to protect your workload and bring governance, including the coverage of legacy systems – Micro-segmentation From Strategy to Execution

16 – A virus in the facebook application that steal your mobile data on Android – Discovered a virus in facebook app that steal data from user – You may consider using « slimsocial » on Android instead of the facebook apps, safer, better for privacy, it works well, and the key is that the app doesn’t send your private data to FB.

17 – I hope you use a password manager and multi factor everywhere – McDonald’s leaks password for Monopoly VIP database to winners – Whenever you give away your data, you must assume it will be compromised, as much as doable, provide fake data.

18 – Your private satellite network ? Review: Hands on with the Swarm Satellite Network Eval Kit

19 – Issue when you have tons of interconnected systems is that decommissioning can be a mess when not properly documented – Latest Atlassian Confluence Flaw Exploited to Breach Jenkins Project Server

20 – If ransomware gets in, you are done. Criminals will promise everything, but they are criminals, they will leak anyways – Ransomware gang threatens to leak data if victim contacts FBI, police – You should have proper security posture so as you never get to this point. At least, start with endpoint protection, such as Cynet XDR (yet we do provide managed offer for this product at work, customers are very happy with it, and the key point is, it works ! )

21 – There is porn, and Netflix and prime video and P2P, so most of internet is leisure and crime – 39% of all internet traffic is from bad bots – Quick hint, you are connected on this very same internet and your traffic is counted in this stat, oh oh….I know, we only watch youcorn ;)

22 – Scraping VS leaks ? Would you know the difference ? Dark Web Scraping

23 – Servers back online, seems they went dark for a while but came back – REvil ransomware’s servers mysteriously come back online – I bet the reason is summer vacations ! What is your take ? They made so much that they took a break ! :P

24 – Manual patch for O365 or get hacked – The cloud is funny – Microsoft shares temp fix for ongoing Office 365 zero-day attacks

25 – A Dash of cyber – In this episode Rod lewis, Brad Rhodes, Alexandre Blanc and Ron Craig will be talking about IoT, Great live we did, don’t miss the replay !

27 – Popcorn time ahead, storm and pouring, data flooding as well ! Cloud computing market to reach $1,251.09 billion by 2028 – if we’d stop all cloud spending, we could pay the whole world debt immediately…. I’ll let you think about this.

28 – Backend of most cloud, HAProxy needs patching ! HAProxy Found Vulnerable to Critical HTTP Request Smuggling Attack – You should patch if you use it.

31 – Zoho patch time ! Zoho patches actively exploited critical ADSelfService Plus bug – Pretty bad exploit given the nature of the product !

Install Slack desktop app on Kali rolling fixing libappindicator3-1 missing dependency

If you try to install Slack desktop app on Kali linux latest rolling as of May 2021, you face a missing dependency of libappindicator3-1 which makes it complicated to get the app installed.

You can force the install with :

dpkg -i –force-depends slack-desktop-4.15.0-amd64.deb

But then when you run an apt update and apt upgrade, you have dependency issue with the same libappindicator.

Dirty workaround is go and edit /var/lib/dpkg/status and remove libappindicator3-1 from the package dependency, then you can apt update and apt upgrade without getting slack removed.

Finally so as you know, libappindicator3-1 have been replaced in kali by libayatana-appindicator ( https://github.com/jgraph/drawio-desktop/issues/504 )

I hope that it will help you.

Have a good day. I hope this helps.
