The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued urgent guidance prompting smartphone users to harden their devices. The warning comes amid ongoing exploitation of commercial spyware targeting mobile messaging apps. Users are advised to enable built-in protections, review app permissions, disable risky fallback features, and ensure secure configuration to reduce their exposure.

Are You Part of a Botnet?

GreyNoise Offers Free Scanner to Find Out

Threat actors frequently hijack unsuspecting devices to build massive "botnets" used for attacks. The good news is, a powerful new tool can help you check. GreyNoise Labs, a renowned threat-monitoring firm, has just released a free IP-scan tool designed for individuals and organizations to quickly assess if their network has exhibited behavior associated with botnet scanning or residential proxy networks.

Why This Matters to You:

Many home and even small business internet connections can be unknowingly enlisted into these malicious networks. This means your internet bandwidth could be used by criminals to:

Scan for vulnerabilities on other networks.
Launch denial-of-service attacks.
Route traffic through your IP address.
Deeper compromised.

While often a subtle form of misuse, it contributes to the global cyber threat landscape and can sometimes lead to your IP address being flagged or blocked by legitimate services.

The Calendar Sweep: Beware of Cal-Spam

Risk: Threat actors are increasingly using calendar invitations to bypass email filters. A malicious invite might appear legitimate but contain a deceptive link or simply attempt to confirm your activity when you respond. Auto-accept features can silently clutter your schedule with malicious links.

Action: Before accepting or declining a shared calendar invite from an unknown sender or one with an unusual meeting description, pause. If suspicious, do not respond (especially do not "Decline" as this often confirms your email is active). Delete the invitation to safely remove the threat without sending a reply.
