Happy Monday everyone!

CrowdStrike is reminding us that just because some of us use Macs, doesn't mean we are malware proof! In this case the cybercriminal group dubbed #COOKIESPIDER was deploying their stealer known as #SHAMOS.

Using a combination of malvertising and the #ClickFix technique, the group would trick their victim's into installing the Shamos stealer which leads to it running "host reconnaissance and data collection tasks, including searching for known cryptocurrency-related wallet files and sensitive credential-based files on disk".

As always, take a read for yourself to see all the details I left out! Enjoy and Happy Hunting!

Happy Monday everyone!

Cisco Talos researchers report on a "malvertising campaign" that involved the #PS1Bot, which is modular and has "several modules delivered to perform a variety of malicious activities on infected systems." It has the capability to capture keystrokes from their victim, conduct reconnaissance and establish persistence.

This campaign involved Search Engine Optimization (SEO) poisoning and/or malvertising where the file name matched the keywords used in this target. The victim received a compressed archive that had a single file named "FULL DOCUMENT" which functioned as the downloader and retrieved the next stage. Powershell modules cam into play later that had the capability to detect which antivirus was being used by the victim, capture screen shots and key strokes, collect wallet information, and gain persistence, which is a pretty creative way of achieving it! But I won't spoil it! Find out for yourself and discover all the other details I left out! Enjoy and Happy Hunting!

Good day everyone!

Somehow I missed this article when it first dropped but at least I found it! The DFIR Report published another great article that involved the #Bumblebee malware as the initial access vector that was installed after a user fell victim to an SEO poisoning campaign. The report states that "the threat actor moved laterally to a domain controller, dumped credentials, installed persistent remote access tools, and exfiltrated data using an SFTP client." The adversary also created two new domain accounts and used one to connect to a domain controller via RDP and dumped the NTDS.dit file using wbadmin.exe.

There are more technical details along with some great queries to use to aid your threat hunting and detection engineering efforts! As always, thank you to the authors for a great report! Happy Hunting!

Happy Friday everyone!

Researchers from the FortiCNAPP team, part of FortiGuard Labs identified a new variant of the #Lcryx ransomware called #Lcrypt0rx. The report states that it "is a relatively new VBScript-based ransomware strain first observed in November 2024" and "exhibits several unusual characteristics that suggest it may have been generated using AI." According to the researchers, it currently only targets Windows machines.

Indicators that led the researchers to believe it is AI generated include:
- Function Duplication
- Incorrect Persistence Mechanisms
- Nonexistent Target Paths
- Invalid Ransom Note URL
- Ineffective AV Disabling

These are just a few indicators and the article provides more details about each indicator, but I am not going to spoil the fun! Go and check it out for yourself! Enjoy and Happy Hunting!

Good day everyone!

Cisco Talos researchers report on a malware-as-a-service (MaaS) operation that was targeting Ukrainian entities and involved the #Amadey trojan, known for "collecting system information and downloading secondary payloads" and the #Emmenhtal downloader.

Behaviors that are observed in this attack include a BUNCH of powershell activity with obfuscation and dropping a legitimate copy of PuTTY.exe. Looking at the technical details, they also us some URLs that may look legitimate to their targets in Ukraine as they add the value "ukraine2" in the URL. Finally, the attack involved multiple variants of the Emmenhtal downloader that were masquerading as MP4 files.

As usual, I glossed over many of the technical details so you can go enjoy the article without me spoiling it! Thanks to the researchers and authors and Happy Hunting!

Happy Wednesday everyone!

News broke that #SaltTyphoon gained access to the U.S. National Guard's network "and, among other things, collected its network configuration and its data traffic with its counterparts’ networks in every other US state and at least four US territories, according to a DOD report. This data also included these networks’ administrator credentials and network diagrams—which could be used to facilitate follow-on Salt Typhoon hacks of these units."

I am posting this as situational awareness and I never try to strike fear in the community, so I want to remind everyone of the great resources that exist out there when you want to threat hunt or you are trying to detect activity related to different #APT groups or malware! Check out the article posted below and check the comments for resources I would recommend using to supplement your threat hunting or blue team efforts! Enjoy and Happy Hunting!

Good day everyone!

Morphisec released an insightful report covering Iranian Cyber Warfare that is targeting the West and other enemies of Iran. The APT involved is #Pay2Key, "an Iranian-backed ransomware-as-as-service (RaaS) operation" that is linked to the Fox Kitten APT group and "closely tied to the well-known #Mimic ransomware."

Normally I call out behaviors and TTPs related but for this report I want to call out the completeness of the report. Not only does it provide more than enough technical details to make actionable in any environment but it also provides a TON of threat intel to support their claims giving the readers and audience an idea if they would be a target or not. It is a great report and I encourage you all to read it! Enjoy and Happy Hunting!

Happy Wednesday everyone!

Elastic Security Labs researchers found a bunch of infostealers being spread by adversaries. In the past we have seen other tools like Brute Ratel and CobaltStrike but this time they decided to use a cracked version of #SHELLTER, another offensive security tool (OST). There are TONS of technical details about the tools they used during the investigation into the tool and what artifacts they found. Interestingly they are also releasing a "dynamic unpacker for binaries protected by SHELLTER. This tool leverages a combination of dynamic and static analysis techniques to automatically extract multiple payload stages from a SHELLTER-protected binary." Thought that was a pretty cool add!

Take a read and get all the important details! Enjoy and Happy Hunting!

Happy Monday everyone and what a way to start it!

I encourage you to read the latest report from The DFIR Report where they document an attack that started with a "password spray attack against an exposed RDP server" and ended in the #RansomHub ransomware strain being deployed in the victim's environment and spread over SMB.

I am going to forgo the brief summary because I truly believe these reports need to be read by you! But a bunch of LOLBINs were leveraged, including PowerShell and Windows Command Shell, of course RDP connections, MimiKatz, the Advanced IP Scanner, and many more! One behavior I will point out is that Persistence was gained by the actors deploying the legitimate RMM tools AteraAgent and Splashtop and then created services to run them!

This is another great example of an extremely thorough report and I hope you enjoy it as much as I do! Enjoy and Happy Hunting!
