I get emails from readers asking for specific malware samples and thought I would make a mini post about it.

Yes, I often obtain samples from various sources for my own research.

I am sometimes too lazy/busy to post them but don't mind sharing.
If you are looking for a particular sample, feel free to ask. I might have it.

Send MD5 (several or few samples). I cannot provide hundreds/thousands of samples or any kind of feeds. If you ask for a particular family, I might be able to help if I already have it.

Unfortunately, I do not have time to do homework for students and provide very specific sets for malware with specific features as well as guarantee the C2s are still active. Send your MD5(s) or at least malware family and I check if I have it :) If i have it, I will either send you or will post on the blog where you can download.

If you emailed me in the past and never got an answer, please remind me. Sometimes emails are long with many questions and I flag them to reply to later, when I have time and they get buried or I forget. It does not happen very often but accept my apologies if it happened to you.

Before you ask, check if it is already available via Contagio or Contagio Mobile.

This story is about a bug generated by g++ and clang compilers (at least)
The condition_variables is a feature on the standard library of c++ (libstdc++), when its compiled statically a weird asm code is generated.

Any example on the link below will crash if its compiled statically:
https://en.cppreference.com/w/cpp/thread/condition_variable

In this case the condition_variable.wait() crashed, but this happens with other methods, a simple way to trigger it:

If this program is compiled dynamically the crash doesn't occur:

Looking the dissasembly there is a surprise created by the compiler:

Compilers:
g++ 9.2.1+20200130-2
clang++ v9

Both compilers are generating the "call 0x00"

If we check this call in a dynamic compiled:

The implementation of condition_variable in github:
https://github.com/gcc-mirror/gcc/blob/b7c9bd36eaacac42631b882dc67a6f0db94de21c/libstdc%2B%2B-v3/include/std/condition_variable

The compilers can't copile well this code in static, and same happens on other condition_variable methods.
I would say the _lock is being assembled improperly in static, is not exacly a null pointer derreference but the effects are the same, executing code at address 0x00 which on linux is a crash on most of cases.

Welcome to my 3rd new tutorial of networking (Routing and Switching). In this blog you will able to watch an interesting video about basic device navigation such as changing device (router or switch) name, configuration of login password, configuring a device information, router IP addresses and many more.

What is router?

Router is a network layer device which is the 3rd layer in the OSI model which is used to communicate different networks. It is an intelligent device fixed at the boundary of network that connects to other networks and responsible for end to end delivery of the packet that requires an IP address which is known as the logical address which is the basic identity of the device just like our identity card number or roll number and so on, for the identification of source and destination devices. Router is the gateway of the network having two interfaces such as inbound and the outbound interface through which the traffic comes in from different networks and comes out traffic to the different networks.

What is an IP address?

Internet protocol (IP) address is a numeric label given to each and every device in the network for the identification of the device just like our roll numbers in collages, universities which identity each and every student uniquely everywhere. So same concept here, it is a logical address which is used whenever the device want to communicate outside the network that means to another network.

What is Switch?

Switch is basically layer 2 device, which is used to connect two or more than two devices with each other in the same network. It is an intelligent device which doesn't allow the broadcast. It requires Media access control (MAC) address to communicate within the network. Now let's move to the video for further.

In the first post of this DNSSEC series, I have shown the problem (DNS vulnerabilities), and in the second post, the "solution." In this third post, I am going to analyze DNSSEC. Can DNSSEC protect the users against all of the attacks? Or just part of them? What about corner cases?

The following list are the attack types from the first post, where DNSSEC can protect the users:

DNS cache poisoning the DNS server, "Da Old way"
DNS cache poisoning, "Da Kaminsky way"
ISP hijack, for advertisement or spying purposes
Captive portals
Pentester hijacks DNS to test application via active man-in-the-middle
Malicious attacker hijacks DNS via active MITM

The following list are the attack types from the first post, where DNSSEC cannot protect the users:

Rogue DNS server set via malware
Having access to the DNS admin panel and rewriting the IP
ISP hijack, for advertisement or spying purposes
Captive portals
Pentester hijacks DNS to test application via active man-in-the-middle
Malicious attacker hijacks DNS via active MITM

If you are a reader who thinks while reading, you might say "What the hell? Am I protected or not???". The problem is that it depends… In the case where the attacker is between you and your DNS server, the attacker can impersonate the DNS server, downgrade it to a non DNSSEC aware one, and send responses without DNSSEC information.

Now, how can I protect against all of these attacks? Answer is "simple":

Configure your own DNSSEC aware server on your localhost, and use that as a resolver. This is pretty easy, even I was able to do it using tutorials.
Don't let malware run on your system! ;-)
Use at least two-factor authentication for admin access of your DNS admin panel.
Use a registry lock (details in part 1).
Use a DNSSEC aware OS.
Use DNSSEC protected websites.
There is a need for an API or something, where the client can enforce DNSSEC protected answers. In case the answer is not protected with DNSSEC, the connection can not be established.

Now some random facts, thoughts, solutions around DNSSEC:

Did you know .SE signed its zone with DNSSEC in September 2005, as the first TLD in the world?
Did you know DNSSEC was first deployed at the root level on July 15, 2010?
Did you know .NL become the first TLD to pass 1 million DNSSEC-signed domain names?
Did you know that Hungary is in the testing phase of DNSSEC (watch out, it is Hungarian)?
Did you know that you can also use and test that cool DNSSEC validator?
Did you know that there are alternative solutions like DNSCrypt?
Did you know that in the future you might be able to enforce HSTS via DNSSEC?
Did you know that in the future you might be able to use certificate pinning via DNSSEC?

That's all folks, happy DNSSEC configuring ;-)

Huh, I have just accidentally deleted this whole post from Z, but then I got it back from my browsing cache. Big up to Nir Sofer for his ChromeCacheView tool! Saved my ass from kickin'! :D
