SANS Stormcast Monday, May 5th: Steganography Challenge; Microsoft Makes Passkeys Default and Moves Away from Authenticator as Password Manager; Magento Components Backdoored. Steganography Challenge Didier published a fun steganography challenge. A solution will be offered on Saturday. https://isc.sans.edu/diary/Steganography+Challenge/31910 Microsoft Makes Passkeys Default Authentication Method Microsoft is now encouraging new users to use Passkeys as the “default” and only login method, further moving away from passwords https://www.microsoft.com/en-us/security/blog/2025/05/01/pushing-passkeys-forward-microsofts-latest-updates-for-simpler-safer-sign-ins/ Microsoft Authenticator Autofill Changes Microsoft will no longer support the use of Microsoft authenticator as a password safe. Instead, it will move users to the password prefill feature built into Microsoft Edge. This change will start in June and should be completed in August at which point you must have moved your credentials out of Microsoft Authenticator https://support.microsoft.com/en-gb/account-billing/changes-to-microsoft-authenticator-autofill-09fd75df-dc04-4477-9619-811510805ab6 Backdoor found in popular e-commerce components SANSEC identified several backdoored Magento e-commerce components. These backdoors were installed as far back as 2019 but only recently activated, at which point they became known. Affected vendors dispute any compromise at this point. https://sansec.io/research/license-backdoor keywords: backdoor; magento; msft; authenticator; passkeys; stegaonography; challenge

A total of 145 vulnerabilities were patched. https://isc.sans.edu/diary/Apple%20Patches%20Everything%3A%20March%2031st%202025%20Edition/31816 VMWare Workstation and Fusion update check broken VMWare’s automatic update check in its Workstation and Fusion products is currently broken due to a redirect added as part of the Broadcom transition https://community.broadcom.com/vmware-cloud-foundation/question/certificate-error-is-occured-during-connecting-update-server NIM Postgres Vulnerability NIM Developers using prepared statements to send SQL queries to Postgres may expose themselves to a SQL injection vulnerability. NIM’s Postgres library does not appear to use actual prepared statements; instead, it assembles the code and the user data as a string and passes them on to the database. This may lead to a SQL injection vulnerability https://blog.nns.ee/2025/03/28/nim-postgres-vulnerability/ keywords: apple; ios; macos; vmware; nim; postres;…

SANS Stormcast Tuesday Apr 1st: Apache Camel Exploits; New Cert Authorities Requirements; Possible Oracle Breach Apache Camel Exploit Attempt by Vulnerability Scans A recently patched vulnerability in Apache Camel has been integrated into some vulnerability scanners, like for example OpenVAS. We do see some exploit attempts in our honeypots, but they appear to be part of internal vulnerablity scans https://isc.sans.edu/diary/Apache%20Camel%20Exploit%20Attempt%20by%20Vulnerability%20Scan%20%28CVE-2025-27636%2C%20CVE-2025-29891%29/31814 New Security Requirements for Certificate Authorities Starting in July, certificate authorities need to verify domain ownership data from multiple viewpoints around the internet. They will also have to use linters to verify certificate requests. https://security.googleblog.com/2025/03/new-security-requirements-adopted-by.html Possible Oracle Breach Oracle still denies being the victim of a data berach as leaked data may show different. https://doublepulsar.com/oracle-attempt-to-hide-serious-cybersecurity-incident-from-customers-in-oracle-saas-service-9231c8daff4a https://www.theregister.com/2025/03/30/infosec_news_in_brief/ https://www.darkreading.com/cyberattacks-data-breaches/oracle-still-denies-breach-researchers-persist keywords: oracle; breach; tls; certificates; camel…

SANS Stormcast Monday, March 31st: Comparing Phishing Sites; DOH and MX Abuse Phishing; opkssh A Tale of Two Phishing Sties Two phishing sites may use very different backends, even if the site itself appears to be visually very similar. Phishing kits are often copied and modified, leading to sites using similar visual tricks on the user facing site, but very different backends to host the sites and reporting data to the miscreant. https://isc.sans.edu/diary/A%20Tale%20of%20Two%20Phishing%20Sites/31810 A Phihsing Tale of DOH and DNS MX Abuse Infoblox discovered a new variant of the Meerkat phishing kit that uses DoH in Javascript to discover MX records, and generate better customized phishing pages. https://blogs.infoblox.com/threat-intelligence/a-phishing-tale-of-doh-and-dns-mx-abuse/ Using OpenID Connect for SSH Cloudflare opensourced it's OPKSSH too.

The underlying vulnerability was patched in January, and security firm Searchlight Cyber revealed details about this vulnerability a couple of weeks ago. https://isc.sans.edu/diary/Sitecore%20%22thumbnailsaccesstoken%22%20Deserialization%20Scans%20%28and%20some%20new%20reports%29%20CVE-2025-27218/31806 Blasting Past Webp Google’s Project Zero revealed details how the NSO BLASTPASS exploit took advantage of a Webp image parsing vulnerability in iOS. This zero-click attack was employed in targeted attack back in 2023 and Apple patched the underlying vulnerability in September 2023. But this is the first “byte by byte” description showing how the attack worked. https://googleprojectzero.blogspot.com/2025/03/blasting-past-webp.html Splunk Vulnerabilities Splunk patched about a dozen of vulnerabilities.

SANS Stormcast Thursday Mar 27th: Classifying Malware with ML; Malicious NPM Packages; Google Chrome 0-day Leveraging CNNs and Entropy-Based Feature Selection to Identify Potential Malware Artifacts of Interest This diary explores a novel methodology for classifying malware by integrating entropy-driven feature selection with a specialized Convolutional Neural Network (CNN). Motivated by the increasing obfuscation tactics used by modern malware authors, we will focus on capturing high-entropy segments within files, regions most likely to harbor malicious functionality, and feeding these distinct byte patterns into our model. https://isc.sans.edu/diary/%5BGuest%20Diary%5D%20Leveraging%20CNNs%20and%20Entropy-Based%20Feature%20Selection%20to%20Identify%20Potential%20Malware%20Artifacts%20of%20Interest/31790 Malware found on npm infecting local package with reverse shell Researchers at Reversinglabs found two malicious NPM packages, ethers-provider2, and ethers-providerz that patch the well known (and not malicious) ethers package to add a reverse shell and downloader. https://www.reversinglabs.com/blog/malicious-npm-patch-delivers-reverse-shell Google Patched Google Chrome 0-day Google patched a vulnerability in Chrome that was already exploited in attacks against media and educational organizations in Russia https://chromereleases.googleblog.com/2025/03/stable-channel-update-for-desktop_25.html keywords: google; chrome; npm; ethers;…
