Palo Alto collected some of the details about this exploit activity that they observed. https://unit42.paloaltonetworks.com/erlang-otp-cve-2025-32433/ WinRAR Exploited WinRAR vulnerabilities are actively being exploited by a number of threat actors. The vulnerability allows for the creation of arbitrary files as the archive is extracted. https://thehackernews.com/2025/08/winrar-zero-day-under-active.html Citrix Netscaler Exploit Updates The Dutch Center for Cyber Security is updating its guidance on recent Citrix Netscaler attacks. Note that the attacks started before a patch became available, and attackers are actively hiding their tracks to make it more difficult to detect a compromise. https://www.ncsc.nl/actueel/nieuws/2025/07/22/casus-citrix-kwetsbaarheid

    SANS Stormcast Sunday, August 03, 2025: Legacy Protocols; Sonicwall SSL VPN Possible 0-Day; Scans for pop3user with guessable password A particular IP assigned to a network that calls itself “Unmanaged” has been scanning telnet/ssh for a user called “pop3user” with passwords “pop3user” or “123456”. I assume they are looking for legacy systems that either currently run pop3 or ran pop3 in the past, and left the user enabled. https://isc.sans.edu/diary/Legacy%20May%20Kill/32166 Possible Sonicwall SSL VPN 0-Day Arcticwolf observed compromised Sonicwall SSL VPN devices used by the Akira group to install ransomware.

PAM-based backdoors can be stealthy, and this one in particular includes various anti-forensics tricks. https://www.nextron-systems.com/2025/08/01/plague-a-newly-discovered-pam-based-backdoor-for-linux/ keywords: pam; linux; backdoor; sonicwall; legacy
