We asked for a sample of the new payload. The Lockbit representative subsequently told us: "Ask the FBI for the payload"

We asked for more information on the Nutanix locker. They told us: "TLP:RED, sorry"

Malware review:
2024-02-27- European diplomats targeted by SPIKEDWIRE with WINELOADER
Notes:
*Zscaler on release of this article did not attribute it to any state-sponsored Threat Actor
*Mandiant later attributed this payload to APT29 March, 22nd 2024 in an article titled: "APT29 Uses WINELOADER to Target German Political Parties"
- Targets specific European diplomats via malicious PDF (0 points)
- Targets carefully enumerated, low volume of malicious PDFs sent (+1 points)
- Malicious PDF masquerading as letter from Ambassador of India for wine tasting event (0 points)
- PDF requires registration to event, links to compromised website (+1 points)
- 'Invitation site' requires guest to download .zip file (-1 point)
- .zip file contains wine.hta which masquerades as invitation event details (0 points)
- .hta file contains malicious javascript, obfuscated with opensource tool (-1 points)
- .hta downloads BASE64 encoded .txt from compromised website (0 points)
- .hta uses certutils.exe to BASE64 decode .txt file (+1 point)
- BASE64 decoded text file transfroms into .zip file, extracted to C:\Windows\Tasks (+1 points)
- .zip extracts sqlwrite.exe and vcruntime140.dll (+1 points)
- APT29 uses DLL sideloading vulnerability (unknown at the time) on sqlwrite.exe to load fake vcruntime140.dll (+2 points)
- Side loaded DLL function se_se_translator pulls RSA encrypted .exe out of DLL (+1 point)
- Side loaded DLL encrypts and decrypts .exe when no longer in use (+2 points)
- .exe has different modules (plugins) for different task (+2 points)
- Modules use DLL Hollowing to inject into randomly selected DLLs (+1 point)
- Each module is downloaded individually from remote C2 (compromised websites) (+2 points)
- Connecting to C2 uses GET HTTP. Sent data is custom made data blobs containing information on modules and commands sent and received (+2 points)
- Persistent achieved by Microsoft signed sqlwriter.exe DLL side loading from Windows Task Scheduler (0 points)
- Memory is zero filled when not used (+1 points)

Following the return of HelloKitty ransomware group (now HelloGookie), the individuals behind HelloKitty ransomware group released more files from CD Projekt Red – the game studio behind The Witcher and Cyberpunk 2077.

On the Windows platform there dozens of ways to achieve persistence, shellcode execution, process injection, – hundreds of different ways to abuse system components
There are tons of little caveats, niches, tweaks and tricks you can do that are often over looked
tl;dr big book

Today we decided to check in with Lockbit ransomware group. The Lockbit ransomware group administrative staff informed us that they're actively working on several new projects – most notably they have developed a new ransomware payload which targets Nutanix

We give APT29's recent APT campaign an B+.
APT29 WINELOADER is modular, multi-staged, practices OPSEC by using multiple compromised websites, has custom built HTTP data blobs. It uses a LOLBIN like technique for persistence and uses a previously undocumented DLL Side Load vulnerability to execute payloads. Random DLL injection is a plus. The encryption and decryption of data is also an interesting plus as it improves its stealth factors and making it more difficult to reverse engineer. The precision of targets and masquerading of an wine tasting event is also interesting – demonstrating research of targets prior to attack. This same attack was later used against German politicians as well.
We are happy to announce we are pregnant, not pregnant, and segfaulting (chemically)

We give Kimsuky Group's recent APT campaign an F.
Unoriginal, generic code, some code dependent on external applications (Winrar) which may not be present on victim machines. Password is hardcoded in payload and easily identifiable. Recycled code and recycled certificate is poor design and lazy. Masqueraded installer not working is lazy. Pushing Mimikatz is also a poor decision, this tool is heavily flagged and is a big red flag.

feege_ spotted a billboard advertisement on the i-95 in Philadelphia, near the Wells Fargo Center, that says:
"Hackers Suck"
"Protect your business. Cover your assets."
13-year-old Marco Liberale has created a proof-of-concept PasteBin C2 botnet in Go. Is it fully cross platform working on Windows, Linux, and Mac.
We are very happy to see such a young person contributing to this research space.

Today a group named 66slavs claimed to have breached the United States National Energy Research Scientific Computing Center (NERSC).
* We have not reviewed the data
* Yes, they watermarked a data breach
"Does {book} cover everything I need to know about malware?"
No book ever released has covered 'everything' about malware. If you wanted a book to cover everything on malware it would weigh 500lbs (226kg) and be cartoonishly large.
Awhile back we heard rumors of a Telegram RCE 0day. We brushed it off as silly memes. Turns out the 0day was 100% real and you're all probably pwned.
It was unveiled on XSS. Nerds celebrated
(joking about pwned part... kind of)
