Exploring Statistical Measures to Predict URLs as Legitimate or Intrusive Using frequency analysis, and training the model with honeypot data as well as log data from legitimate websites allows for a fairly simple and reliable triage of web server logs to identify possible malicious activity. https://isc.sans.edu/diary/Exploring%20Statistical%20Measures%20to%20Predict%20URLs%20as%20Legitimate%20or%20Intrusive%20%5BGuest%20Diary%5D/31822 Critical Unexploitable Ivanti Vulnerability Exploited CVE-2025-22457 In February, Ivanti patched CVE-2025-22457. At the time, the vulnerability was not considered to be exploitable. Mandiant now published a blog disclosing that the vulnerability was exploited as soon as mid-march https://cloud.google.com/blog/topics/threat-intelligence/china-nexus-exploiting-critical-ivanti-vulnerability/ WinRAR MotW Vulnerability CVE-2025-31334 WinRAR patched a vulnerability that would not apply the Mark of the Web correctly if a compressed file included symlinks. This may make it easier to trick a victim into executing code downloaded from a website. https://nvd.nist.gov/vuln/detail/CVE-2025-31334 Microsoft Warns of Tax-Related Scam With the US personal income tax filing deadline only about a week out, Microsoft warns of commonly deployed scams that they are observing related to income tax filings https://www.microsoft.com/en-us/security/blog/2025/04/03/threat-actors-leverage-tax-season-to-deploy-tax-themed-phishing-campaigns/ Oracle Breach Update https://www.bloomberg.com/news/articles/2025-04-02/oracle-tells-clients-of-second-recent-hack-log-in-data-stolen…

Surge in Scans for Juniper t128 Default User Lasst week, we dedtect a significant surge in ssh scans for the username t128 . This user is used by Juniper s Session Smart Routing, a product they acquired from 128 Technologies which is the reason for the somewhat unusual username. https://isc.sans.edu/diary/Surge%20in%20Scans%20for%20Juniper%20%22t128%22%20Default%20User/31824 Vulnerable Verizon API Allowed for Access to Call Logs An API Verizon offered to users of its call filtering application suffered from an authentication bypass vulnerability allowing users to access any Verizon user s call history.

Apple Patches Everything Apple released updates for all of its operating systems. Most were released on Monday with WatchOS patches released today on Tuesday. Two already exploited vulnerabilities, which were already patched in the latest iOS and macOS versions, are now patched for older operating systems as well. 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/…

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.

Sitecore "thumbnailsaccesstoken" Deserialization Scans (and some new reports) CVE-2025-27218 Our honeypots detected a deserialization attack against the CMS Sitecore using a thumnailaccesstoken header. 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. None of them are rated critical, but a vulnerability rated High allows authenticated users to execute arbitrary code. https://advisory.splunk.com/ Firefox 0-day Patched Mozilla patched a sandbox escape vulnerability that is already being exploited. https://www.mozilla.org/en-US/security/advisories/mfsa2025-19/…

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…
