⚠️PSA: VPN & RDWeb password guessing attacks have been observed originating from IP addresses consistently across the following subnets:
85.239.59.0/24
85.239.58.0/24
85.239.57.0/24
85.239.56.0/24
➡️ Check for low & slow password guessing attempts and successful logins.
⚠️PSA: Curated Intel members in DFIR have noticed a trend in exploitation of CVE-2024-57727 in the SimpleHelp RMM tool to deploy Medusa ransomware.
➡️ This tool is often used by IT Managed Service Providers (MSPs) to remotely control customer endpoints and have been impacted.

⚠️PSA: Curated Intel DFIR has noticed a new trend among Akira Ransomware cases in Summer 2024. For a while, Akira has been exploiting Cisco ASA devices.
➡️ They are now targeting SonicWall SSL-VPNs for access with no MFA (!) and weak passwords (!). Other TTPs remain the same 🔍

We had some good convos in the @CuratedIntel community today based on this @thecyberwire interview
Really interesting that @C_C_Krebs says the *most important skill* he looks for in a CTI analyst is their “ability to communicate risk to businesses” 🗣️⚠️
