Cybersecurity researchers found the first known harmful Microsoft Outlook add-in used in a real attack. The add-in, called AgreeTo, was once a normal calendar tool but was abandoned after 2022. An attacker took control of its expired web address and replaced it with a fake Microsoft login page. When users entered their passwords, the attacker stole them. Over 4,000 accounts were affected.

This happened because Outlook add-ins load content from a web link that can change over time. Microsoft checks the add-in when it is first approved, but it does not always monitor the live web content later. If a web address expires and someone else takes it, they can use it for phishing or other attacks.

How users can protect themselves:

• Avoid installing old or unused add-ins.
• Remove add-ins you no longer use.
• Turn on multi-factor authentication (MFA) for your Microsoft account.
• Check the web address carefully before entering your...

Microsoft is warning that cybercriminals are increasingly targeting Apple macOS users with data-stealing malicious software, expanding beyond their traditional focus on Windows systems.

The company says attackers are using deceptive online ads, fake websites, and phishing messages to trick people into installing malicious software. These scams often appear when users search for popular tools, including AI-related apps or utility software, and are sometimes delivered through platforms like Google Ads.

Once installed, the malware can quietly steal sensitive information such as saved passwords, browser data, financial details, and even cryptocurrency credentials. In some cases, attackers also gain access to cloud accounts and developer information.

Microsoft noted that some of these campaigns are linked to organized threat groups and have been spread not only through email but also through messaging apps like WhatsApp. The stolen data is then sent back to the...

Security researchers found a fake add-on for Visual Studio Code that claimed to be a free AI helper for Moltbot, a popular tool. The add-on appeared in the official VS Code store but secretly installed harmful software that let attackers take control of users’ computers. Moltbot does not have an official VS Code add-on, and attackers used its popularity to trick people. Microsoft has now removed the fake add-on.

After installation, the add-on ran automatically whenever VS Code was opened and downloaded harmful files from the attackers. This allowed them to quietly access and control the computer. Researchers also warned that many Moltbot setups are not well protected, leaving chat messages and login details exposed. Since Moltbot can send messages and perform actions for users, attackers could pretend to be them, steal information, or spread more harmful add-ons.

Safety Tips for Users:

• Install extensions only from trusted and verified...

Cybersecurity researchers are warning about a new scam on LinkedIn where hackers use private messages to trick people into downloading harmful files.

According to security firm ReliaQuest, attackers contact professionals through LinkedIn, build trust, and convince them to download what appears to be a harmless file. In reality, the download secretly installs malicious software on the victim’s computer.

Once opened, the file allows attackers to quietly gain ongoing access to the system, steal sensitive information, and potentially move deeper into company networks—without the victim noticing anything unusual.

Researchers say this method is especially dangerous because most companies focus on protecting email, while social media messages often go unmonitored. This gives attackers an easier way to bypass security defenses.

ReliaQuest noted that the campaign appears widespread and targets users across different industries and regions. The company warned that...

Researchers have discovered a new attack called Reprompt that can steal sensitive data from AI chatbots like Microsoft Copilot. The attack works with just one click on a real Microsoft link and does not need any plugins or extra user actions. It tricks the chatbot into following hidden instructions from the attacker’s server, even after the chat is closed, so data can be taken without the user knowing. Microsoft has fixed this issue, and enterprise users of Microsoft 365 Copilot are safe. This attack shows that AI systems can’t always tell the difference between safe user instructions and harmful ones, and similar attacks have been found on many AI platforms.

Safety tips for users:

• Think before you click: Avoid clicking on unexpected AI links in emails or messages.
• Limit personal info: Avoid entering sensitive data into AI tools unless necessary.
• Check...
