Common Security Concerns

These are the risks journalists face every day.

State-sponsored spyware targeting journalists

State-sponsored spyware is real. CoreLock flags known-bad tools and risky command lines among running apps, but targeted state-level attacks can go beyond what a consumer scanner detects.

Protecting confidential sources

A compromised device means compromised sources. CoreLock's privacy audit shows which apps hold camera, microphone and file permissions.

Working from hostile environments

Reporting from unstable regions means untrusted networks and physical device risk. CoreLock lists your apps' open connections on any network, and Shields can turn on the macOS firewall and Stealth mode.

Receiving files from unknown senders

Tips come as documents, images, and archives from people you cannot vet. CoreLock checks files in your Downloads folder against a built-in list of known-malware hashes and its own malware-signature (YARA) rules.

Features That Matter to Journalists

CoreLock is not a generic antivirus. These are the capabilities that make a real difference for your work.

Running Apps Check

CoreLock flags known-bad tools and risky command lines, like reverse shells, among running apps. It cannot guarantee detection of targeted spyware.

Local-First Scanning

Scanning runs on your Mac. AI explanations are off by default. If you turn them on, a summary is sent to our servers: your 25 busiest programs (name, ID, CPU and memory), connection counts and disk totals. Never your files. File reputation checks are also off by default. If you turn them on, fingerprints (hashes, not contents) of scanned files are checked against an online malware-hash database.

Open Connections

See your apps' open connections by IP address and port, so you can review any process talking to an address you do not recognize. It doesn't show hostnames or processes owned by root.

File Scanning

Checks files in Downloads (and, with Files › Quick scan, Desktop and LaunchAgents) against a built-in list of known-malware hashes and CoreLock's malware-signature (YARA) rules. A signature match is a reason to look at the file, not proof it's harmful.

Permission Audit

See which apps have camera, microphone, and files and folders access, and open Privacy & Security in System Settings to turn off anything that should not be there.

Recommended Plan

Pro ($9.99/mo) removes the AI analysis limit. The free tier (unlimited scans, 3 AI analyses per day) lets you try it first.

Frequently Asked Questions

Can CoreLock detect Pegasus or similar spyware?

No tool can guarantee that, and CoreLock does not claim to detect Pegasus. It flags known-bad tools and risky command lines among running apps, but targeted state-level attacks can go beyond what a consumer scanner detects.

What does CoreLock send off my Mac?

Scanning runs on your Mac. AI explanations are off by default. If you turn them on, a summary is sent to our servers: your 25 busiest programs (name, ID, CPU and memory), connection counts and disk totals. Never your files. File reputation checks are also off by default. If you turn them on, fingerprints (hashes, not contents) of scanned files are checked against an online malware-hash database. See the Privacy page for details.

Is it safe to scan files from anonymous sources?

CoreLock checks files locally against a built-in list of known-malware hashes and its own malware-signature (YARA) rules. File contents are never uploaded. If you turn on file reputation checks (off by default), fingerprints (hashes, not contents) are checked against an online malware-hash database.

Does CoreLock work in countries with restricted internet?

Core scanning runs on your Mac. Signing in, AI analysis, AI chat, and license checks need an internet connection.
