Residential proxies are hiding in plain sight inside enterprise networks

10 June 2026 @ 2:06 pm

Residential proxy services route internet traffic through consumer devices to make connections appear to originate from real home IP addresses. Security researchers have tracked their use by threat actors for credential stuffing, ad fraud, and denial-of-service operations. What has been less understood is how widely those services have already penetrated enterprise networks, often without IT or security teams knowing. As it turns out, the risks posed by residential proxies to enterprise networks are widespread. Infoblox analyzed billions of DNS resolutions across its Threat Defense Cloud customer base and revealed just how a big a pro

From the data center to the edge: How to build secure, effective enterprise AI infrastructure

9 June 2026 @ 8:17 pm

While hyperscalers and neo-cloud providers may get the lion’s share of attention for providing AI infrastructure, many enterprises are taking a build-it-themselves approach to meet their specific AI requirements. The success of such projects is crucial to achieving business objectives, yet companies face significant challenges as they try to scale pilots to production. Organizations must keep up with the dynamic, ever-changing demands that AI applications place on compute and network infrastructure, from the data center to the edge. That means architecting systems to grow as demand warrants and to avoid performance bottlenecks. The architecture must also account for AI-driven security

Attackers exploiting unpatched Cisco SD-WAN flaw

8 June 2026 @ 9:53 pm

Cisco warns customers of an actively exploited high-severity vulnerability in Catalyst SD-WAN Manager, an enterprise network management system that has been targeted by hackers multiple times in the past. Located in the command-line interface, the flaw allows authenticated attackers to escalate privileges to root and take over the entire system. The vulnerability, tracked as CVE-2026-20245, is rated 7.8 (high) on the CVSS scale instead of critical because it requires local access and netadmin privileges to exploit. These privileges can be obtained via stolen credentials or by exploiting authentication bypass flaws, such as CVE-2026-20245 or CVE-2026-20127, which were fixed in May and Fe

Does any CA still issue certificates compatible with Starfield Class 2 Certification Authority?

I have a fleet of legacy IoT devices that trust only the root certificate: Starfield Class 2 Certification Authority I need to host a temporary HTTPS endpoint for a one-time firmware update, but the devices cannot be updated until they can successfully validate a server certificate. Does anyone know of a public CA that still issues certificates whose chain can be validated using Starfield Class 2 Certification Authority, or offers a legacy/alternate chain compatible with that root? This is for embedded device compatibility, not browser compatibility.

Apache2.4 legacy MD5 password hash for authentication

9 June 2026 @ 5:39 pm

So I have this legacy system that is being migrated to a new architecture. The database stores passwords as plain MD5 hashes, as in passwordhash = md5('plaintext') Yes, I know this is insecure, I will have to live with that for now. The system runs Apache 2.2 with the mod_auth_mysql module. The HTTP authentication configuration looks like this: AuthType basic AuthMYSQLEnable On AuthMySQLHost dbserver ... AuthMySQLPwEncryption md5 This setup apparently supports plain md5 password hashes for authentication. It appears that in Apache 2.4 the authentication architecture has changed, and I have found no way to specify legacy MD5 password hashes for HTTP authentication. It is my understanding that the so-called MD5 hash in Apache 2.4 basic authentication is an apache specific algorithm, so it fails against plain MD5 hashes. The same goes for digest authentication. Any idea how to get A

Granting batch script admin privilege independent of who calls it

9 June 2026 @ 11:26 am

I have a remote machine which executes a number of measurement tasks. Users are supposed to execute a startup via command line (login via SSH). The machine has one non-admin user which is supposed to be able to start a new session of data acquisition which happens via python scripts whenever they deem it necessary. Any previous instance of these scripts will have to be terminated for that purpose. This currently is done automatically at the start of a batch script with a command like taskkill /F /FI "WINDOWTITLE eq check_logfile" /T. However this command fails from an unpriviliged account. Thus the question: is there a way for an unpriviliged user to terminate an existing instance of the programmes and start them in a pristine state. On a unix system I could kill my own process without further priviliges or allow a user to execute a priviliged command when I set the SUID bit for that programm's permissions. Is there any equivalent for either I ca

Google Cloud OAuth 2.0 Client ID creation fails instantly when adding authorized redirect URI

This happens in a new project with Google Sheets and Drive APIs enabled, no organization restrictions, and after trying different browsers and incognito mode.

Postfix multi-instance configuration issues
