Imagine this, you setup a server and it has a really weak administrator password! Now let’s imagine you expose RDP to the internet. How long would it take to get pw3nd?
Well we did this, using a custom configuration to make this safe, we setup a Windows Server, setup an administrator account with the password of ‘password’ and monitored the logs! So let’s see what we found.

‘An improper neutralization of special elements used in an OS command (‘OS Command Injection’) vulnerability [CWE-78] in FortiSIEM may allow an unauthenticated attacker to execute unauthorized code or commands via crafted TCP requests.’

This analysis was conducted using data from Defused, enrichment from IPINFO and SHODAN and then analysis using an LLM (GROK) (so take the analysis with a pinch of salt):

Another day another exploit in the wild it seems! (ok I’m a bit slow to this one). Using Defused Cyber’s Honeypots we have another packet to analyse:

This weeks been an interesting one, I’ve been doing quite a bit of research recently with my friend Simo from Defused defusedcyber.com. Simo has built a new emulated honeypot platform, and anyone that know’s me knows I love honeypots, deception and intel sharing to help defenders and to impose cost on the baddies! (technical terms here ok!)

Ok About 4 months ago I made a quick PHP page to be used as a custom ALARM for detecting intruders in a network. This has a quick call to a Slack Web Hook but clearly could link to anything (.e.g. DISCORD, TEAMS etc.)
Today I wanted to deploy this but I thought I’d throw it into CHATGPT to see how it summarizes code:
So here we go:

A path traversal vulnerability and exploit just dropped in the wild for a specific version of Apache (Apache/2.4.49). This vulnerability allows an unauthenticated attacker to execute a path traversal attack (and now shown RCE if MOD_CGI is enabled) to read files outside of the virtual directory path bounds. This only affects a single version of Apache, there’s a fair few of these online, however it’s very unlikely all are vulnerable. The vulnerability requires specific permissions to be configured.

Now this might come to a shock to some of you but I’m not actually (as my LinkedIn profile currently says) Tony Stark! I know, shocking but it’s true. Why I’m experimenting with this will hopefully be apparent after reading this post (although this isn’t an explanation specifically). What I’m looking at is how deception is used from a range of perspectives from marketing, cybercrime and how we can use deception in a positive way, to actively defend ourselves from the cyber criminals!

You may have seen my post on hacking back and how it’s a nightmare that screams inexperience when I hear it (don’t get me wrong there are very limited times when it might be useful from a national defence perspective/intelligence services but that isn’t really ‘hacking back’ in my book, they are already working that space so it’s not a retaliation) however I’ve been spurred on this morning by a tweet I saw from @1njection:
After tweeting a quick reply, I thought I had put together a quick blog on aggressive active defences! (not wordy much). Read more “Aggressively Defending Information Systems”
