It's been a heck of a week, with tonnes of great research and tooling that I'm sure you're going to get a kick out of - check out our wrap-up for all the news!:

https://opalsec.substack.com/p/soc-goulash-weekend-wrap-up-16042023

Kaspersky researchers shone a light on the Dark Web trade in Google Play Loaders - a service to help inject malware into legitimate, and supposedly vetted apps, with guarantees of >1 week up-time and the option to boost your spread with targeted Ads.

#Nokoyawa ransomware have clearly got some talent on their team, having abused a #CLFS 0-day prior to Microsoft patching it last week - one of 5 different exploits they've used, mind you - and they appear to have a new, distinct ransomware strain in rotation, too.

There's heaps more great threat reporting, including a report that #FIN7 and former #Conti (#FIN12/#WizardSpider) members are collaborating on a new backdoor, and a crypto-mining campaign that may be the canary in the coal mine, indicating broader uptake of BYOVD and IPFS by low-level operators.

The #QueueJumper vulnerability from last week looks primed to explode in coming days, with a no-fix vulnerability in Microsoft Intune capping off a lousy week for Windows admins struggling to keep their networks secure.

TOOLING. Ooooh boy, this was a good week for tooling and tradecraft, ladies and gentlemen.

The #redteam have a new port of the SharpHound AD enumeration tool for Cobalt Strike; a great reference piece on leveraging stolen Office tokens to bypass MFA and access cloud workloads, and a list of keywords to avoid when crafting stealthy PowerShell scripts.

The #blueteam have a script to help tweak VM settings to circumvent malware anti-analysis checks; Procmon for macOS, and a lightweight bastion host to help redirect and record traffic sent to honeypots in your network.

This was a fun one to write up, with heaps of interesting reads and takeaways to be had. Get amongst it!

Happy Monday folks, I hope you had a restful weekend and managed to take a breather from all things cyber! Time to get back into it though, so let me give you hand - catch up on the week’s infosec news with the latest issue of our newsletter:

https://opalsec.substack.com/p/soc-goulash-weekend-wrap-up-09e?sd=pf

#Emotet are back and are using…OneNote lures? ISO disk images? Malvertising? Nah – they’re sticking with tier tried and true TTPs – their Red Dawn maldoc template from last year; macro-enabled documents as lures, and null-byte padding to evade automated scanners.

We’ve highlighted a report on the Xenomorph #Android Banking Trojan, which added support for targeting accounts of over 400 banks; automated bypassing of MFA-protected app logins, and a Session Token stealer module. With capabilities like these becoming the norm, is it time to take a closer look at the threat Mobile Malware could pose to enterprise networks?

North Korean hackers have demonstrated yet again that they’re tracking and integrating the latest techniques, and investing in malware development. A recent campaign saw eight new pieces of malware distributed throughout the kill chain, leveraging #Microsoft #InTune to deliver payloads and an in-memory dropper to abuse the #BYOVD technique and evade EDR solutions.

A joint investigation by #Mandiant and #SonicWall has unearthed a two-year campaign by Chinese actors, enabled through exploitation of unpatched SMA100 appliances and delivery of tailored payloads. A critical vulnerability reported by #Fortinet this week helps reinforce the point that perimeter devices need to be patched with urgency, as it’s a well-documented target for Chinese-affiliated actors.

#HiatusRAT is a novel malware targeting #DrayTek routers, sniffing network traffic and proxying C2 traffic to forward-deployed implants. TTPs employed in recent #BatLoader and #Qakbot campaigns are also worth taking note of, as is #GoBruteforcer, a new malware family targeting specific web server applications to brute force logins and deploy an IRC bot for C2.

Those in Vulnerability Management should take particular note of the #Veeam vulnerability, which appears trivial to exploit and actually delivers plaintext credentials to the attacker. CISA have also taken note of nearly 40k exploit attempts of a 2 year old code-exec-as-root vulnerability in the #VMWare Cloud Foundation product in the last two months, so make sure you’re patched against it.

#Redteam members have some excellent reading to look forward to, looking at HTTP request smuggling to harvest AD credentials and persisting with a MitM Exchange server, as well as a detailed post that examines #CobaltStrike’s reflective loading capability;

The #blueteam has some great tradecraft tips from @inversecos on #Azure DFIR, as well as tools to help scan websites for malicious objects, and to combat the new #Stealc #infostealer and well-established Raccoon Stealer.

Catch all this and much more in this week's newsletter:
