Security failures rarely arrive loudly. They slip in through trusted tools, half-fixed problems, and habits people stop questioning. This week’s recap shows that pattern clearly. Attackers are moving faster than defenses, mixing old tricks with new paths. “Patched” no longer means safe, and every day, software keeps becoming the entry point. What follows is a set of small but telling signals. Short updates that, together, show how quickly risk is shifting and why details can’t be ignored. ⚡ Threat of the Week Improperly Patched Flaw Exploited Again in Fortinet Firewalls — Fortinet confirmed that it's working to completely plug a FortiCloud SSO authentication bypass vulnerability following reports of fresh exploitation activity on fully-patched firewalls. "We have identified a number of cases where the exploit was to a device that had been fully upgraded to the latest release at the time of the attack, which suggested a new attack path," the company said. The activi...

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 ...

The North Korean threat actor known as Konni has been observed using PowerShell malware generated using artificial intelligence (AI) tools to target developers and engineering teams in the blockchain sector. The phishing campaign has targeted Japan, Australia, and India, highlighting the adversary's expansion of the targeting scope beyond South Korea , Russia , Ukraine , and European nations , Check Point Research said in a technical report published last week. Active since at least 2014, Konni is primarily known for its targeting of organizations and individuals in South Korea. It's also tracked as Earth Imp, Opal Sleet, Osmium, TA406, and Vedalia. In November 2025, the Genians Security Center (GSC) detailed the hacking group's targeting of Android devices by exploiting Google's asset tracking service, Find Hub, to remotely reset victim devices and erase personal data from them, signaling a new escalation of their tradecraft. As recently as this month, Konni ha...

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...

The Russian nation-state hacking group known as Sandworm has been attributed to what has been described as the "largest cyber attack" targeting Poland's power system in the last week of December 2025. The attack was unsuccessful, the country's energy minister, Milosz Motyka, said last week. "The command of the cyberspace forces has diagnosed in the last days of the year the strongest attack on the energy infrastructure in years," Motyka was quoted as saying. According to a new report by ESET, the attack was the work of Sandworm, which deployed a previously undocumented wiper malware codenamed DynoWiper (aka Win32/KillFiles.NMO). The links to Sandworm are based on overlaps with prior wiper activity associated with the adversary, particularly in the aftermath of Russia's military invasion of Ukraine in February 2022. The Slovakian cybersecurity company, which identified the use of the wiper as part of the attempted disruptive attack aimed at the...
