Magecart threat actor rolls out convincing modal forms
To ensnare new victims, criminals will often devise schemes that attempt to look as realistic as possible. Having said that, it is not every day that we see the fraudulent copy exceed the original piece. While following up on an ongoing Magecart credit card skimmer campaign, we were almost fooled by a payment form that looked so well done we thought it was real. The threat actor used original logos from the compromised store and customized a web element known as a modal to perfectly hijack the checkout page.

Analyzing an arm64 mach-O version of LockBit
The relevance of this macOS specimen is well articulated in their tweet: “Lockbit ransomware group has created their first MacOS-based payload. We believe this is the first time a large ransomware threat group has developed a payload for Apple products.” vx-underground Ok, so even though it’s the weekend, we have what appears to be a new macOS malware specimen from one of the more notorious ransomware gangs! Coupled with the fact that this may be, (as noted by @VXUnderground), “the first time a large ransomware threat group has developed a payload for Apple products” …I was intrigued to decided to dig right in!
Vice Society: A Tale of Victim Data Exfiltration via PowerShell, aka Stealing off the Land
The Vice Society ransomware gang exfiltrated victim network data using a custom Microsoft PowerShell script. We dissect how each function of it works.
Nokoyawa ransomware attacks with Windows zero-day
in February 2023, Kaspersky technologies detected a number of attempts to execute similar elevation-of-privilege exploits on Microsoft Windows servers belonging to small and medium-sized businesses in the Middle East, in North America, and previously in Asia regions. These exploits were very similar to already known Common Log File System (CLFS) driver exploits that we analyzed previously, but we decided to double check and it was worth it – one of the exploits turned out to be a zero-day, supporting different versions and builds of Windows, including Windows 11. The exploit was highly obfuscated with more than 80% of the its code being “junk” elegantly compiled into the binary, but we quickly fully reverse-engineered it and reported our findings to Microsoft. Microsoft assigned CVE-2023-28252 to the Common Log File System elevation-of-privilege vulnerability, and a patch was released on April 11, 2023, as part of April Patch Tuesday.
