Google Gemini Prompt Injection Flaw Exposed Private Calendar Data via Malicious Invites

Google Gemini Prompt Injection Flaw Exposed Private Calendar Data via Malicious Invites

Jan 19, 2026 Artificial Intelligence / Vulnerability
Cybersecurity researchers have disclosed details of a security flaw that leverages indirect prompt injection targeting Google Gemini as a way to bypass authorization guardrails and use Google Calendar as a data extraction mechanism. The vulnerability, Miggo Security's Head of Research, Liad Eliyahu, said, made it possible to circumvent Google Calendar's privacy controls by hiding a dormant malicious payload within a standard calendar invite. "This bypass enabled unauthorized access to private meeting data and the creation of deceptive calendar events without any direct user interaction," Eliyahu said in a report shared with The Hacker News. The starting point of the attack chain is a new calendar event that's crafted by the threat actor and sent to a target. The invite's description embeds a natural language prompt that's designed to do their bidding, resulting in a prompt injection. The attack gets activated when a user asks Gemini a completely inno...

⚡ Weekly Recap: Fortinet Exploits, RedLine Clipjack, NTLM Crack, Copilot Attack & More

Jan 19, 2026 Hacking News / Cybersecurity
In cybersecurity, the line between a normal update and a serious incident keeps getting thinner. Systems that once felt reliable are now under pressure from constant change. New AI tools, connected devices, and automated systems quietly create more ways in, often faster than security teams can react. This week's stories show how easily a small mistake or hidden service can turn into a real break-in. Behind the headlines, the pattern is clear. Automation is being used against the people who built it. Attackers reuse existing systems instead of building new ones. They move faster than most organizations can patch or respond. From quiet code flaws to malware that changes while it runs, attacks are focusing less on speed and more on staying hidden and in control. If you're protecting anything connected—developer tools, cloud systems, or internal networks—this edition shows where attacks are going next, not where they used to be. ⚡ Threat of the Week Critical Fortinet Flaw Comes Under...
DevOps & SaaS Downtime: The High (and Hidden) Costs for Cloud-First Businesses

DevOps & SaaS Downtime: The High (and Hidden) Costs for Cloud-First Businesses

Jan 19, 2026 DevOps / SaaS Downtime
Just a few years ago, the cloud was touted as the "magic pill" for any cyber threat or performance issue. Many were lured by the "always-on" dream, trading granular control for the convenience of managed services. In recent years, many of us have learned (often the hard way) that public cloud service providers are not immune to attacks and SaaS downtime, hiding behind the Shared Responsibility cushion. To stay operational, competitive, and resilient in today's threat landscape, teams must move beyond the dependency on SaaS providers and understand what cyber resilience really means. The Myth of DevOps SaaS Resilience In 2024 alone, popular DevOps SaaS platforms—like GitHub, Jira, or Azure DevOps— experienced 502 incidents in total, which resulted in degraded performance and outages totaling over 4,755 hours . The conclusion is clear: Entrusting "the big players" with your source code, development metadata, and workflow projects doesn't make your business immune to downtime and subs...

AMD, which is tracking the vulnerability as CVE-2025-29943 (CVSS v4 ...
CrashFix Chrome Extension Delivers ModeloRAT Using ClickFix-Style Browser Crash Lures

CrashFix Chrome Extension Delivers ModeloRAT Using ClickFix-Style Browser Crash Lures

Jan 19, 2026 Malware / Windows Security
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 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 Asylum Ambuscade), with the threat ...
Security Bug in StealC Malware Panel Let Researchers Spy on Threat Actor Operations

Security Bug in StealC Malware Panel Let Researchers Spy on Threat Actor Operations

Jan 19, 2026 Malware / Threat Intelligence
Cybersecurity researchers have disclosed a cross-site scripting (XSS) vulnerability in the web-based control panel used by operators of the StealC information stealer, allowing them to gather crucial insights on one of the threat actors using the malware in their operations. "By exploiting it, we were able to collect system fingerprints, monitor active sessions, and – in a twist that will surprise no one – steal cookies from the very infrastructure designed to steal them," CyberArk researcher Ari Novick said in a report published last week. StealC is an information stealer that first emerged in January 2023 under a malware-as-a-service (MaaS) model, allowing potential customers to leverage YouTube as a primary mechanism – a phenomenon called the YouTube Ghost Network – to distribute the malicious program by disguising it as cracks for popular software. Over the past year, the stealer has also been observed being propagated via rogue Blender Foundation files and a soc...

Black Basta Ransomware Leader Added to EU Most Wanted and INTERPOL Red Notice

Jan 17, 2026 Law Enforcement / Cybercrime
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...

OpenAI to Show Ads in ChatGPT for Logged-In U.S. Adults on Free and Go Plans

Jan 17, 2026 Artificial Intelligence / Data Privacy
OpenAI on Friday said it would start showing ads in ChatGPT to logged-in adult U.S. users in both the free and ChatGPT Go tiers in the coming weeks, as the artificial intelligence (AI) company expanded access to its low-cost subscription globally. "You need to know that your data and conversations are protected and never sold to advertisers," OpenAI said . "And we need to keep a high bar and give you control over your experience, so you see truly relevant, high-quality ads—and can turn off personalization if you want." The company has positioned advertising as a way to ensure that the benefits of artificial general intelligence – a term used to describe a stage in machine learning when an AI system can reach or surpass human-level intelligence – can be made more accessible to the masses. In addition, it can be "transformative" for small businesses and emerging brands trying to compete, it added. It also emphasized that ads do not influence responses...
GootLoader Malware Uses 500–1,000 Concatenated ZIP Archives to Evade Detection

GootLoader Malware Uses 500–1,000 Concatenated ZIP Archives to Evade Detection

Jan 16, 2026 Malvertising / Threat Intelligence
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...

LOTUSLITE Backdoor Targets U.S. Policy Entities Using Venezuela-Themed Spear Phishing

LOTUSLITE Backdoor Targets U.S. Policy Entities Using Venezuela-Themed Spear Phishing

Jan 16, 2026 Malware / Cyber Espionage
Security experts have disclosed details of a new campaign that has targeted U.S. government and policy entities using politically themed lures to deliver a backdoor known as LOTUSLITE . The targeted malware campaign leverages decoys related to the recent geopolitical developments between the U.S. and Venezuela to distribute a ZIP archive ("US now deciding what's next for Venezuela.zip") containing a malicious DLL that's launched using DLL side-loading techniques. It's not known if the campaign managed to successfully compromise any of the targets. The activity has been attributed with moderate confidence to a Chinese state-sponsored group known as Mustang Panda (aka Earth Preta, HoneyMyte, and Twill Typhoon), citing tactical and infrastructure patterns. It's worth noting that the threat actor is known for extensively relying on DLL side-loading to launch its backdoors, including TONESHELL. "This campaign reflects a continued trend of targeted spear...
China-Linked APT Exploited Sitecore Zero-Day in Critical Infrastructure Intrusions

China-Linked APT Exploited Sitecore Zero-Day in Critical Infrastructure Intrusions

Jan 16, 2026 Zero-Day / Cyber Espionage
A threat actor likely aligned with China has been observed targeting critical infrastructure sectors in North America since at least last year. Cisco Talos, which is tracking the activity under the name UAT-8837 , assessed it to be a China-nexus advanced persistent threat (APT) actor with medium confidence based on tactical overlaps with other campaigns mounted by threat actors from the region. The cybersecurity company noted that the threat actor is "primarily tasked with obtaining initial access to high-value organizations," based on the tactics, techniques, and procedures (TTPs) and post-compromise activity observed. "After obtaining initial access — either by successful exploitation of vulnerable servers or by using compromised credentials — UAT-8837 predominantly deploys open-source tools to harvest sensitive information such as credentials, security configurations, and domain and Active Directory (AD) information to create multiple channels of access to their v...

Researchers Reveal Reprompt Attack Allowing Single-Click Data Exfiltration From Microsoft Copilot

Researchers Reveal Reprompt Attack Allowing Single-Click Data Exfiltration From Microsoft Copilot

Jan 15, 2026 Prompt Injection / Enterprise Security
Cybersecurity researchers have disclosed details of a new attack method dubbed Reprompt that could allow bad actors to exfiltrate sensitive data from artificial intelligence (AI) chatbots like Microsoft Copilot in a single click, while bypassing enterprise security controls entirely. "Only a single click on a legitimate Microsoft link is required to compromise victims," Varonis security researcher Dolev Taler said in a report published Wednesday. "No plugins, no user interaction with Copilot." "The attacker maintains control even when the Copilot chat is closed, allowing the victim's session to be silently exfiltrated with no interaction beyond that first click." Following responsible disclosure, Microsoft has addressed the security issue. The attack does not affect enterprise customers using Microsoft 365 Copilot. At a high level, Reprompt employs three techniques to achieve a data‑exfiltration chain - Using the "q" URL parameter in...

Model Security Is the Wrong Frame – The Real Risk Is Workflow Security

Model Security Is the Wrong Frame – The Real Risk Is Workflow Security

Jan 15, 2026 Data Security / Artificial Intelligence
As AI copilots and assistants become embedded in daily work, security teams are still focused on protecting the models themselves. But recent incidents suggest the bigger risk lies elsewhere: in the workflows that surround those models. Two Chrome extensions posing as AI helpers were recently caught stealing ChatGPT and DeepSeek chat data from over 900,000 users. Separately, researchers demonstrated how prompt injections hidden in code repositories could trick IBM's AI coding assistant into executing malware on a developer's machine. Neither attack broke the AI algorithms themselves.  They exploited the context in which the AI operates. That's the pattern worth paying attention to. When AI systems are embedded in real business processes, summarizing documents, drafting emails, and pulling data from internal tools, securing the model alone isn't enough. The workflow itself becomes the target. AI Models Are Becoming Workflow Engines To understand why this matters,...
4 Outdated Habits Destroying Your SOC's MTTR in 2026

4 Outdated Habits Destroying Your SOC's MTTR in 2026

Jan 15, 2026 Threat Detection / Malware Analysis
It's 2026, yet many SOCs are still operating the way they did years ago, using tools and processes designed for a very different threat landscape. Given the growth in volumes and complexity of cyber threats, outdated practices no longer fully support analysts' needs, staggering investigations and incident response. Below are four limiting habits that may be preventing your SOC from evolving at the pace of adversaries, and insights into what forward-looking teams are doing instead to achieve enterprise-grade incident response this year. 1. Manual Review of Suspicious Samples Despite advances in security tools, many analysts still rely heavily on manual validation and analysis. This approach creates friction on every step, from processing samples to switching between tools and manually correlating the findings.  Manually dependent workflows are often the root cause of alert fatigue and delayed prioritization, subsequently slowing down response. These challenges are especially re...
