Spring4Shell – Not Quite as Fictional as We First Thought
By Austin Miller
When another vulnerability with -4Shell caught my attention, I was a little suspicious. Could this seriously be as potentially damaging as the infamous Log4Shell? And the initial prognosis from the wider cybersecurity community confirmed my suspicions – it seemed to only affect a particular custom configuration of Java Spring Boot, meaning that most people would be safe.
Here we are a week later and there have been numerous exploits uploaded to GitHub showing exactly how the adversary can exploit systems running this vulnerable version of Spring. To make matters worse, these exploits have been leaked and anyone running this suspect Spring software is in danger of being exploited. For that reason, IT teams are now back on red alert. But how does Spring4Shell work and how can we check for this exploit in our own systems?

Okta breach – a View of the Genesis Market Place
The Okta breach, without doubt, is InfoSec World’s number one breach of 2022. At least, for now. Although brilliant in terms of publicity that the breach generated for the Hackers, it wasn’t rocket science. Not even a master criminal or two at work to pull it off. Audacious of course, hacking one of the foremost Identity & Access Management Providers takes some nerve, if not ‘brass neck’.
Today I’m not going to focus on the actual attack or the various stages of it, but if you haven’t read the Intrusion Timeline here’s a quick summary; upon initial compromise, the attackers (literally) used a search engine to find a Privilege escalation tool then quickly followed by another Bing Search to find a Process Explorer tool. Process Hacker duly downloaded from GitHub and it was seemingly quite easy enough to stop the XDR agent from finally downloading Mimikatz used to escalate privileges. Off the shelf tools, Bing & GitHub – breach did.
As I said, Okta isn’t the real focus and not the moral of this story. What we know is that the group previously took the credit in a blaze of glory for breaching EA Games security and allegedly gaining access to game source code and other related internal tools. Some of the code for FIFA 2021, Battlefield, and tools for the Frostbite Engine. In all 780Gb of data was claimed to have been compromised with the sale of EA Proprietary Frameworks, SDKs. All of which was then advertised for sale in various hacking forum posts.

T1027: Obfuscated Files or Information
By Austin Miller
Obfuscation, a word you will only ever find in cybersecurity documents. Obfuscated (or obscuring) malware allows various types of information to be covertly transmitted to systems, creating a Trojan horse to the adversary’s Troy-invading malicious files. As you would expect, a Trojan horse virus is a clear example of obfuscation but understanding other forms of trickery is key to effective cybersecurity work.
Hiding malicious files, code, commands, configurations, and other information was a key part of 13% of all malware samples analyzed by Picus and is a common tactic for defense evasion. Changing the form and size of data, hiding known malicious elements, and obscuring or removing indicators are all tools in the adversary’s kit, so understanding the various tactics they use is key to improving your security posture

Malicious APK setting up suspicious C2 server
It appears to be a bad week for Android users as yet another critically dangerous piece of malware has been found to be targeted attacks on the Google-owned software. This time, the malware installs a program named Process Manager and gains 18 permissions. This is concerning behavior on its own, but it also adds information about calls, the contact list, and other files before collecting all files on the device, saving information to the JSON files, and reporting to a C2 server.
At present, this Process Manager application is installed alongside the Roz Dhan: Earn Wallet cash application. At first appearance, this seems to be another case of hackers taking aim at cryptocurrency enthusiasts that are wanting to make some easy money with various attacks.
