Hackers Are Using Fake Invitations to Take Over Your PC

Cybercriminals are sending counterfeit email invitations that, when clicked, install a backdoor on the victim's computer, allowing hackers full control. The scam often involves downloading a file named “invites.msi,” which is a Windows Installer package. This file can install ScreenConnect, a legitimate remote support tool that can be exploited by attackers to monitor screens, access files, and deploy additional malware. Many security engines fail to flag this software as malicious, making it difficult to detect. If someone suspects they have fallen victim to this scam, they should disconnect from the internet, check for and uninstall any remote management software, run a comprehensive antivirus scan, change passwords for critical accounts, enable two-factor authentication, inform their IT department if applicable, and consider performing a full Windows reset. The scam originated from a compromised email account, which was used to send the malicious link to contacts. Implementing two-factor authentication and using a password manager can help prevent such incidents. Users should be cautious of any email invitations that require downloading and running installer files.

Max Messenger: A fake data breach with genuine consequences?

A user claimed to have breached Max but later clarified that no large-scale breach or critical vulnerabilities were found. False claims about data breaches can cause significant reputational damage, as demonstrated by a Russian hacking group that falsely claimed to have accessed Epic Games' data, which was later admitted to be a ruse. Similarly, EuroCar reported that fake breach reports may have been generated by ChatGPT, misleading customers. Russian users are distrustful of the Max app, perceived as buggy and insecure. The Russian Federal Security Service blocked its integration with government services due to encryption concerns. Although the government pressures citizens to adopt Max, many may install it without using it regularly. There is skepticism among Russian citizens regarding the app's security, making them susceptible to damaging rumors. Future claims about Max Messenger data breaches are anticipated. Recommendations for organizations to protect against misinformation include maintaining a good reputation, being transparent if a breach occurs, and investing in digital forensics to counter false claims.

Why you need a VPN if you’re using ChatGPT or other AI chatbots

AI chatbots collect a significant amount of personal information, including email address, username, subscription plan, messages sent, responses generated, features used, timestamps, device/browser type, IP address, and any files or images shared. Although ChatGPT claims not to sell user data, the extensive data collected raises privacy concerns, especially in the event of a data breach. Users may not be fully aware of potential changes in data policies, which could allow for future selling or misuse of their data. To protect their data while using chatbots, individuals are advised to utilize a VPN service.

What Happens When Startups Outgrow DIY Cyber Protection

Startups often begin with basic cybersecurity measures, such as free antivirus solutions and default settings, which may seem sufficient during early growth. However, as they expand, the complexity of their security needs increases due to larger customer databases, more cloud services, remote teams, and heightened expectations from stakeholders. Remaining with DIY security can lead to significant risks, including data breaches, operational disruptions, and lost opportunities with larger clients. Signs that a startup needs to enhance its security include handling sensitive data, preparing for audits, rapid onboarding, and growing concerns about cyber risk. Transitioning to a structured cybersecurity approach involves continuous threat detection, centralized management, automated responses, and clear visibility into risks. A unified cybersecurity platform can simplify security management, reduce blind spots, and support growth while ensuring robust protection. Recognizing the need for improved cybersecurity is crucial for startups to secure their operations and build credibility as they scale.

She is a cybersecurity expert and former Director of the Cybersecurity and Infrastructure Security Agency (CISA). Palo Alto Networks has released security updates for a vulnerability (CVE-2026-0227) with a CVSS score of 7.7 affecting its GlobalProtect Gateway and Portal, which can cause a denial-of-service condition in PAN-OS software. The January 2026 security update from Microsoft has caused connection and authentication failures in Azure Virtual Desktop and Windows 365, affecting users across various Windows versions. Microsoft is working on a resolution. The chief constable of West Midlands Police acknowledged an error by Microsoft’s Copilot AI in generating a fictional intelligence report. Microsoft has not confirmed Copilot's involvement. Britain’s National Cyber Security Centre (NCSC) has collaborated with Five Eyes partners to provide guidance on securing industrial operational technology, highlighting risks associated with remotely monitored systems.

Hackers Use Fake Windows BSOD To Spread Malware

Security researchers have identified a social engineering campaign that mimics the Windows Blue Screen of Death (BSOD) to deceive users into installing a remote access Trojan (RAT). The campaign, named PHALT#BLYX, begins with phishing emails that appear to be legitimate cancellation notices from travel websites, leading victims to a fake login page and an interactive CAPTCHA. This culminates in a full-screen imitation of the BSOD, prompting users to follow instructions that ultimately allow attackers to gain control of their computers. The attackers use a “ClickFix” process that involves executing commands through native Windows tools like PowerShell and MSBuild, making detection more challenging. The malware delivered is an obfuscated version of DCRat, which provides attackers with remote control capabilities, keylogging, and the ability to download additional malware. The campaign primarily targets hotels and hospitality businesses in Europe, exploiting the urgency of front-desk staff to respond to apparent technical issues. Indicators of a fake BSOD include the ability to interact with the screen, requests to execute commands via Windows tools, and the presence of CAPTCHA prompts. Organizations are advised to train employees, implement application control, enhance email and web defenses, and prepare for incident response to mitigate risks associated with such attacks.
