CISA Adds Actively Exploited SolarWinds Serv-U DoS Flaw to KEV Catalog

CISA Adds Actively Exploited SolarWinds Serv-U DoS Flaw to KEV Catalog

Jun 06, 2026 Vulnerability / Patch Management
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a high-severity security flaw impacting SolarWinds Serv-U multi-protocol file server software to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-28318 (CVSS score: 7.5), is a denial-of-service (DoS) bug that causes the service to crash under certain conditions. CISA described it as an uncontrolled resource consumption vulnerability that results in a DoS condition. "SolarWinds Serv-U is susceptible to specially crafted POST requests that crash the Serv-U service without authentication using Content-Encoding: deflate," SolarWinds said in an advisory released earlier this week. The issue has been addressed in SolarWinds Serv-U version 15.5.4 HF1. As mitigations, it's advised to limit access to known addresses and block any request containing "content-encoding" since the vulnerable service does not r...

It got stupid again. The internet still feels held together with tape. Bad plugins, old bugs, fake tools, trusted apps doing shady things. Same mess, new wrapper. And now the weird stuff is normal. Forums go down and come back worse. Cheap hackers get better toys. AI starts breaking real systems. Great. Read the whole thing before it ruins your week anyway.

Every time you think the industry has finally stopped doing some reckless, low-effort crap, somebody spins up a fresh box full of sketchy loaders, fake installers, recycled social-engineering bait, and enough exposed infrastructure to make you wonder if prod is just a public beta now - meanwhile some researcher casually drops a technique that turns a "minor" foothold into total account compromise because apparently six digits and blind trust were all that stood between your vault and getting absolutely pwned. Cool. Great. Love that for us. Then there's the supply chain mess... signed binaries, poisoned updates, legit tooling getting hijacked like it's still 2017, plus a few reports this week that feel less like advanced tradecraft and more like watching skiddies discover low-hanging fruit with enterprise branding slapped on top. The weird part isn't that it works. The weird part is how damn easy it still is. Anyway. Grab caffeine. Let's get into it. ...

AI Chatbot Recommendations Redirect Users to Cryptojacking Malware Sites

AI Chatbot Recommendations Redirect Users to Cryptojacking Malware Sites

May 27, 2026 Artificial Intelligence / Threat Intelligence
Microsoft has warned of an active cryptojacking campaign that makes use of artificial intelligence (AI) chatbot interactions as a mechanism for surfacing malicious download sites. "This emerging delivery technique extends social engineering beyond conventional search results and increases the visibility of malicious software recommendations," Microsoft Defender Experts and the Microsoft Defender Security Research Team said in a report published Tuesday. The activity, per the tech giant, impersonates legitimate system utilities like CrystalDiskInfo, HWMonitor, Display Driver Uninstaller, FurMark, K-Lite Codec Pack, and PDFgear, likely in an attempt to target users who own high-performance GPUs. The idea is to focus on compromising systems with higher mining value than indiscriminately infecting a large number of machines, it added. The goals of the campaign are not merely financially motivated. The threat actors have also been found to establish persistent remote acce...
MFA Prompt Bombing: Why Your Second Factor Isn't Saving You

MFA Prompt Bombing: Why Your Second Factor Isn't Saving You

May 26, 2026 Password Security / Social Engineering
Multi-factor authentication (MFA) was supposed to close a critical gap in identity security. It meant that, even if an attacker possessed the account credentials, they couldn't log in without the second factor. While that logic was sound, attackers have now figured out that they don't need to steal the second factor: they just need the user to hand it over. If your workforce authenticates with push-based MFA, this attack is a live threat to your organization today. Tools like Specops Secure Access are built specifically to close that gap, but before getting into the fix, it's worth understanding how this technique works. How MFA prompt bombing works The attack requires three key elements to work: Valid account credentials, usually sourced from breached password dumps on the dark web A login portal that uses push-based MFA (such as a VPN, Microsoft 365, Okta, or Duo) A victim who is alerted every time the attacker tries the login Attackers repeatedly tri...
