    SANS Stormcast Tuesday, May 12th: Apple Patches; Unipi Technologies Scans; Apple Updates Everything Apple patched all of its operating systems. This update ports a patch for a recently exploited vulnerability to older versions of iOS and macOS. https://isc.sans.edu/diary/31942 It Is 2025, And We Are Still Dealing With Default IoT Passwords And Stupid 2013 Router Vulnerabilities Versions of the Mirai botnet are attacking devices made by Unipi Technology. These devices are using a specific username and password combination. In addition, this version of the Mirai botnet will also attempt exploits against an old Netgear vulnerability. https://isc.sans.edu/diary/It%20Is%202025%2C%20And%20We%20Are%20Still%20Dealing%20With%20Default%20IoT%20Passwords%20And%20Stupid%202013%20Router%20Vulnerabilities/31940 Output Messenger Vulnerability The internal messenger application “Output Messenger” is currently used in sophisticated attacks. Attackers are exploiting a path traversal vulnerability that has not been fixed. https://www.outputmessenger.com/cve-2025-27920/ Commvault Correction Commvault’s patch indeed fixes the recent vulnerability. The “Pioneer Release” Will Dormann used to experiment will only offer patches after it has been registered, which leads to an error when assessing the patch’s efficacy. https://www.darkreading.com/application-security/commvault-patch-works-as-intended keywords: commvault; output messenger; mirai; unipi; apple

    SANS Stormcast Monday, May 11th: Steganography Challenge; End-of-Life Routers; ASUS Driverhub; RV-Tools SEO Poisoning Steganography Challenge Didier revealed the solution to last weekend’s cryptography challenge. The image used the same encoding scheme as Didier described before, but the columns and rows were transposed. https://isc.sans.edu/forums/diary/Steganography%20Challenge%3A%20My%20Solution/31912/ FBI Warns of End-of-life routers The FBI is tracking larger botnets taking advantage of unpatched routers. Many of these routers are end-of-life, and no patches are available for the exploited vulnerabilities. The attackers are turning the devices into proxies, which are resold for various criminal activities. https://www.ic3.gov/PSA/2025/PSA250507 ASUS Driverhub Vulnerability ASUS Driverhub software does not properly check the origin of HTTP requests, allowing a CSRF attack from any website leading to arbitrary code execution. https://mrbruh.com/asusdriverhub/ RV-Tools SEO Poisoning Varonis Threat Labs observed SEO poisoning being used to trick system administrators into installing a malicious version of RV Tools. The malicious version includes a remote access tool leading to the theft of credentials https://www.varonis.com/blog/seo-poisoning#initial-access-and-persistence keywords: steganography; fbi; router; seq; rv-tools; asus; driverhub
