This week's updates show how small changes can create real problems. Not loud incidents, but quiet shifts that are easy to miss until they add up. The kind that affects systems people rely on every day. Many of the stories point to the same trend: familiar tools being used in unexpected ways. Security controls are being worked on. Trusted platforms turning into weak spots. What looks routine on the surface often isn't. There's no single theme driving everything — just steady pressure across many fronts. Access, data, money, and trust are all being tested at once, often without clear warning signs. This edition pulls together those signals in short form, so you can see what's changing before it becomes harder to ignore. Major cybercrime forum takedown FBI Seizes RAMP Forum The U.S. Federal Bureau of Investigation (FBI) has seized the notorious RAMP cybercrime forum. Visitors to the forum's Tor site and its clearnet domain, ramp4u...

Google on Tuesday revealed that multiple threat actors, including nation-state adversaries and financially motivated groups, are exploiting a now-patched critical security flaw in RARLAB WinRAR to establish initial access and deploy a diverse array of payloads. "Discovered and patched in July 2025, government-backed threat actors linked to Russia and China as well as financially motivated threat actors continue to exploit this n-day across disparate operations," the Google Threat Intelligence Group (GTIG) said . "The consistent exploitation method, a path traversal flaw allowing files to be dropped into the Windows Startup folder for persistence, underscores a defensive gap in fundamental application security and user awareness." The vulnerability in question is CVE-2025-8088 (CVSS score: 8.8), which was patched by WinRAR version 7.13 released on July 30, 2025. Successful exploitation of the flaw could allow an attacker to obtain arbitrary code execution by c...

If there's a constant in cybersecurity, it's that adversaries are always innovating. The rise of offensive AI is transforming attack strategies and making them harder to detect. Google's Threat Intelligence Group , recently reported on adversaries using Large Language Models (LLMs) to both conceal code and generate malicious scripts on the fly, letting malware shape-shift in real-time to evade conventional defenses. A deeper look at these novel attacks reveals both unprecedented sophistication and deception.  In November 2025, Anthropic reported on what it described as the first known "AI-orchestrated cyber espionage campaign." This operation featured AI integrated throughout the stages of attack, from initial access to exfiltration, which was executed largely autonomously by the AI itself.  Another recent trend concerns ClickFix-related attacks using steganography techniques (hiding malware within image files) that slipped past signature-based scans. Skillfully disguised ...

A new multi-stage phishing campaign has been observed targeting users in Russia with ransomware and a remote access trojan called Amnesia RAT. "The attack begins with social engineering lures delivered via business-themed documents crafted to appear routine and benign," Fortinet FortiGuard Labs researcher Cara Lin said in a technical breakdown published this week. "These documents and accompanying scripts serve as visual distractions, diverting victims to fake tasks or status messages while malicious activity runs silently in the background." The campaign stands out for a couple of reasons. First, it uses multiple public cloud services to distribute different kinds of payloads. While GitHub is mainly used to distribute scripts, binary payloads are staged on Dropbox. This separation complicates takedown efforts, effectively improving resilience. Another "defining characteristic" of the campaign, per Fortinet, is the operational abuse of defendnot to d...

Cybersecurity researchers have disclosed details of a new ransomware family called Osiris that targeted a major food service franchisee operator in Southeast Asia in November 2025. The attack leveraged a malicious driver called POORTRY as part of a known technique referred to as bring your own vulnerable driver (BYOVD) to disarm security software, the Symantec and Carbon Black Threat Hunter Team said. It's worth noting that Osiris is assessed to be a brand-new ransomware strain, sharing no similarities with another variant of the same name that emerged in December 2016 as an iteration of the Locky ransomware. It's currently not known who the developers of the locker are, or if it's advertised as a ransomware-as-a-service (RaaS). However, the Broadcom-owned cybersecurity division said it identified clues that suggest the threat actors who deployed the ransomware may have been previously associated with INC ransomware (aka Warble). "A wide range of living off...

Most of this week's threats didn't rely on new tricks. They relied on familiar systems behaving exactly as designed, just in the wrong hands. Ordinary files, routine services, and trusted workflows were enough to open doors without forcing them. What stands out is how little friction attackers now need. Some activity focused on quiet reach and coverage, others on timing and reuse. The emphasis wasn't speed or spectacle, but control gained through scale, patience, and misplaced trust. The stories below trace where that trust bent, not how it broke. Each item is a small signal of a larger shift, best seen when viewed together. Spear-phishing delivers custom backdoor Operation Nomad Leopard Targets Afghanistan Government entities in Afghanistan have been at the receiving end of a spear-phishing campaign dubbed Operation Nomad Leopard that employs bogus administrative documents as decoys to distribute a backdoor named FALSECUB by means o...

Cybersecurity researchers have disclosed details of an ongoing campaign dubbed KongTuke that used a malicious Google Chrome extension masquerading as an ad blocker to deliberately crash the web browser and trick victims into running arbitrary commands using ClickFix -like lures to deliver a previously undocumented remote access trojan (RAT) dubbed ModeloRAT. This new escalation of ClickFix, observed earlier this month, has been codenamed CrashFix by Huntress. KongTuke , also tracked as 404 TDS, Chaya_002, LandUpdate808, and TAG-124, is the name given to a traffic distribution system (TDS) known for profiling victim hosts before redirecting them to a payload delivery site that infects their systems. Access to these compromised hosts is then handed off to other threat actors, including ransomware groups, for follow-on malware delivery. Some of the cybercriminal groups that have leveraged TAG-124 infrastructure include Rhysida ransomware , Interlock ransomware , and TA866 (aka Asylu...

Ukrainian and German law enforcement authorities have identified two Ukrainians suspected of working for the Russia-linked ransomware-as-a-service (RaaS) group Black Basta. In addition, the group's alleged leader, a 35-year-old Russian national named Oleg Evgenievich Nefedov (Нефедов Олег Евгеньевич), has been added to the European Union's Most Wanted and INTERPOL's Red Notice lists, authorities noted. "According to the investigation, the suspects specialized in technical hacking of protected systems and were involved in preparing cyberattacks using ransomware," the Cyber Police of Ukraine said in a statement.  The agency said the accused individuals functioned as "hash crackers," who specialize in extracting passwords from information systems using specialized software. Once the credential information was obtained, members of the ransomware group broke into corporate networks and ultimately deployed ransomware and extorted money to recover the e...

The JavaScript (aka JScript) malware loader called GootLoader has been observed using a malformed ZIP archive that's designed to sidestep detection efforts by concatenating anywhere from 500 to 1,000 archives. "The actor creates a malformed archive as an anti-analysis technique," Expel security researcher Aaron Walton said in a report shared with The Hacker News. "That is, many unarchiving tools are not able to consistently extract it, but one critical unarchiving tool seems to work consistently and reliably: the default tool built into Windows systems." This leads to a scenario where the archive cannot be processed by tools like WinRAR or 7-Zip, and, therefore, prevents many automated workflows from analyzing the contents of the file. At the same time, it can be opened by the default Windows unarchiver, thereby ensuring that victims who fall victim to the social engineering scheme can extract and run the JavaScript malware. GootLoader is typically distrib...

The internet never stays quiet. Every week, new hacks, scams, and security problems show up somewhere. This week's stories show how fast attackers change their tricks, how small mistakes turn into big risks, and how the same old tools keep finding new ways to break in. Read on to catch up before the next wave hits. Unauthenticated RCE risk Security Flaw in Redis A high-severity security flaw has been disclosed in Redis (CVE-2025-62507, CVSS score: 8.8) that could potentially lead to remote code execution by means of a stack buffer overflow. It was fixed in version 8.3.2. JFrog's analysis of the flaw has revealed that the vulnerability is triggered when using the new Redis 8.2 XACKDEL command, which was introduced to simplify and optimize stream cleanup. Specifically, it resides in the implementation of xackdelCommand(), a function responsible for parsing and processing the list of stream IDs supplied by the user. "The core ...

Chinese-speaking threat actors are suspected to have leveraged a compromised SonicWall VPN appliance as an initial access vector to deploy a VMware ESXi exploit that may have been developed as far back as February 2024. Cybersecurity firm Huntress, which observed the activity in December 2025 and stopped it before it could progress to the final stage, said it may have resulted in a ransomware attack. Most notably, the attack is believed to have exploited three VMware vulnerabilities that were disclosed as zero-days by Broadcom in March 2025: CVE-2025-22224 (CVSS score: 9.3), CVE-2025-22225 (CVSS score: 8.2), and CVE-2025-22226 (CVSS score: 7.1). Successful exploitation of the issue could permit a malicious actor with admin privileges to leak memory from the Virtual Machine Executable (VMX) process or execute code as the VMX process. That same month, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the flaws to the Known Exploited Vulnerabilities (KEV) ca...

As organizations plan for 2026, cybersecurity predictions are everywhere. Yet many strategies are still shaped by headlines and speculation rather than evidence. The real challenge isn't a lack of forecasts—it's identifying which predictions reflect real, emerging risks and which can safely be ignored. An upcoming webinar hosted by Bitdefender aims to cut through the noise with a data-driven outlook on where organizations are already falling short, and what those failures signal for the year ahead. Rather than speculative scenarios, the session focuses on threats that are actively reshaping the attack landscape today. The webinar examines the convergence of three major trends. First, ransomware is evolving beyond opportunistic attacks toward targeted disruptions designed to maximize operational and business impact. Second, the rapid and often uncontrolled adoption of AI within organizations is creating an internal security crisis, eroding traditional perimeter assumptions and exp...

This week's stories show how fast attackers change their tricks, how small mistakes turn into big risks, and how the same old tools keep finding new ways to break in. Read on to catch up before the next wave hits. Honeypot Traps Hackers Hackers Fall for Resecurity's Honeypot Cybersecurity company Resecurity revealed that it deliberately lured threat actors who claimed to be associated with Scattered LAPSUS$ Hunters ( SLH ) into a trap, after the group claimed on Telegram that it had hacked the company and stolen internal and client data. The company said it set up a honeytrap account populated with fake data designed to resemble real-world business data and planted a fake account on an underground marketplace for compromised credentials after it uncovered a threat actor attempting to conduct malicious activity targeting its resou...

It's getting harder to tell where normal tech ends and malicious intent begins. Attackers are no longer just breaking in — they're blending in, hijacking everyday tools, trusted apps, and even AI assistants. What used to feel like clear-cut "hacker stories" now looks more like a mirror of the systems we all use. This week's findings show a pattern: precision, patience, and persuasion. The newest campaigns don't shout for attention — they whisper through familiar interfaces, fake updates, and polished code. The danger isn't just in what's being exploited, but in how ordinary it all looks. ThreatsDay pulls these threads together — from corporate networks to consumer tech — revealing how quiet manipulation and automation are reshaping the threat landscape. It's a reminder that the future of cybersecurity won't hinge on bigger walls, but on sharper awareness. Open-source tool exploited Abuse of Nezha for Post-Exploitation Bad actors are le...
