Storm-2603 is slipping through SharePoint’s cracks and locking the doors behind it. The suspected China-based threat group is exploiting two SharePoint vulnerabilities to deploy Warlock ransomware. The group uses Mimikatz for credential theft and moves laterally with PsExec. At least 400 organizations have already been impacted. When your router has more holes than a sieve, it’s time to worry. Researchers uncovered several critical vulnerabilities in Weidmueller IE-SR-2TX industrial routers. These flaws allow remote attackers to gain root-level code execution, posing a significant risk to industrial networks and critical infrastructure. Chaos by name, chaos by method. A new RaaS group called Chaos is conducting high-impact ransomware campaigns through a number of tactics, using remote management tools for long-term access. Chaos supports multiple platforms and avoids politically sensitive or healthcare-related victims, offering automated control panels and individualized encryption keys per infection.

A trusted source turned treacherous. Hackers launched a supply chain attack on Arch Linux by slipping malware into three AUR packages. These packages silently deployed a RAT that gave attackers persistent control over infected machines. The backdoor executed during installation and remained undetected for 46 hours before Arch’s security team intervened. No login needed, just code execution. Cisco has confirmed active exploitation of three zero-day RCE flaws in its ISE. Attackers can exploit these bugs via crafted API requests to run arbitrary commands, upload malware, and escalate privileges to root - all without authentication. Mimo is getting stealthier and greedier. The financially motivated group has moved from targeting Craft CMS to Magento, exploiting PHP-FPM vulnerabilities to deploy malware via fileless techniques. Its monetization play is twofold - mining Monero through cryptojacking and running proxyjacking operations via IPRoyal Pawns. The group also targets AWS environments by probing for SSH access using hardcoded usernames.

Greedy Sponge isn’t just soaking up data, it’s draining bank accounts. Active since 2021, this financially motivated threat group targets Mexican organizations using a modified AllaKore RAT and SystemBC malware to carry out fraud. Delivered via spear-phishing and drive-by downloads, the malware is geofenced to avoid exposure and now includes server-side payload delivery and secondary infections to bypass detection. What looks like a Google Doc or Steam message may be ACRStealer in disguise. Now rebranded as AmateraStealer, this infostealer uses the Dead Drop Resolver method to communicate via legitimate services, recently adopting stronger evasion features. Ongoing updates and variants have made Amatera one of the most active and elusive stealers currently circulating. Two bugs, one big hole. Apache Jena has been found vulnerable to critical flaws (CVE-2025-49656 and CVE-2025-50151) that allow administrators to create or access files outside intended directories, undermining system sandboxing. Though both require admin privileges, they pose serious risks in shared environments or if admin credentials are compromised. Users are urged to upgrade to version 5.5.0 to patch the flaws.

The H2Miner botnet has resurfaced with updated scripts that mine Monero, kill rival malware, and deploy multiple malware. Bundled with it is Lcrypt0rx, a likely AI-generated ransomware that exhibits sloppy logic, malformed syntax, and weak encryption using XOR. Cisco Talos uncovered a MaaS campaign targeting Ukraine, where attackers used Amadey malware and GitHub repositories to stage payloads. The setup mimics tactics from a SmokeLoader phishing operation, with obfuscated JavaScript loaders and Emmenthal plugins helping evade detection and filter-based defenses. In a sharp postmortem from Pwn2Own Berlin, VMware patched four zero-day flaws exploited during the contest. Three high-severity bugs let attackers break out of guest VMs, while a fourth in VMware Tools leaks sensitive host info. Separately, the Scanception campaign is sneaking into inboxes via QR code phishing PDFs.

A harmless-looking app on Google Play may have a malicious twin elsewhere. A new Konfety variant uses the same package name as a legitimate app but hides the real payload in a lookalike version distributed through third-party stores. It employs obfuscation tactics to evade detection, while leveraging the CaramelAds SDK. Some malware no longer travels through links or attachments, it hides in plain text. Researchers have spotted attackers embedding payloads in DNS records, allowing malware to slip past traditional security tools. By encoding binaries as hex and retrieving them during DNS resolution, this technique avoids common detection points and delivers disruptive code without a visible trace. One sandbox escape makes five. Google patched a high-severity Chrome flaw that lets attackers break out of the browser’s sandbox using crafted HTML and unvalidated GPU commands. The update also addressed issues in V8 and WebRTC, but only CVE-2025-6558 was under active exploitation, making it the fifth Chrome zero-day of the year.

A quiet but deliberate campaign is now zeroing in on Southeast Asia’s trade secrets. HazyBeacon, a newly identified Windows backdoor, is targeting government entities with an eye on sensitive tariff and trade data. It uses DLL side-loading and communicates through AWS Lambda URLs, helping it blend in with legitimate cloud activity while quietly collecting targeted documents. Developers are once again in the crosshairs of North Korean threat actors. As part of the ongoing Contagious Interview campaign, attackers have pushed 67 malicious npm packages carrying XORIndex, a malware loader designed to steal browser data, crypto wallet info, and deploy Python-based backdoors. With over 17,000 downloads and manipulated package metrics, the threat is both widespread and deceptive. An invisible prompt is all it takes to turn Gemini into a phishing assistant. Attackers are exploiting Google’s Gemini AI for Workspace by hiding malicious instructions in emails using HTML and CSS. When Gemini generates a summary, it unknowingly includes phishing content redirecting users to malicious sites. Suggested defenses focus on stripping hidden content and warning users not to rely on AI summaries for security cues.
