How to View Network Activity

The Galaxy S24 makes it easy to start monitoring your network connections. First, head to Settings > Connections > Data Usage.

Here you’ll be able to see how much mobile data each app has used over various time intervals. Check if any apps have unusually high data usage, especially apps that typically don’t require an internet connection to function. Sudden data spikes could indicate suspicious activity.

For even more detailed analytics, download a network monitoring app from the Google Play Store. Apps like Network Log or My Data Manager offer real-time views of all network traffic going to and from your device.

They provide in-depth insight like the IP addresses of sites and servers your device is connecting with, the ports and protocols used, data upload/download speeds, and more. Study these apps regularly to become familiar with your normal connection patterns.

Suspicious Signs to Watch For

Once you have visibility into your device’s network connections, watch for these common red flags that could mean your data is at risk:

Frequent unknown connections, especially to foreign countries you don’t normally connect with. These could indicate a malware infection or that your device is part of a botnet.
High data usage from unexpected apps that don’t typically require internet access. For example, data spikes from your Calendar, Contacts, or Settings apps could signify malware sending data from your device.
Consistent network connections during odd hours when you know your phone is idle and not in active use. Botnets often connect devices at night.
Signs of unauthorized account access like unknown login attempts, locked out accounts, or changed passwords can also indicate your network is compromised.

Take note if you observe any of these patterns over an extended time. Don’t ignore your instincts if network activity seems abnormal. The sooner you investigate issues, the less data you stand to lose.

Analyze Specific Connections

If you spot suspicious network activity, take time to analyze the specifics of the connections. Open your network monitoring app and note any unfamiliar IP addresses that your device is communicating with frequently.

Run these IP addresses through a WHOIS lookup tool to determine where they originate from and other public details. If an address comes from a suspicious country or organization, that’s even more reason for concern.

You can also Google the names of apps or processes showing heavy network usage that you’re not familiar with. See if other Android users have reported similar issues and whether the behavior is considered normal or not. The crowdsourced info should give clarity on whether the connections are legitimate or not.

Getting down into the specifics will help you determine if network activity is normal or the sign of a larger threat at play. Don’t neglect due diligence in studying data usage trends or odd IP address connections.

Further Steps if Suspicious Activity Found

If your network analysis confirms suspicious behavior, take prompt action to secure your device. Start by changing passwords for all accounts logged into the device. Enable two-factor authentication anywhere it’s available for an added account security blanket.

Also scan your device for malware, as that could be enabling unauthorized connections. Use a highly-rated mobile antivirus app to perform a deep threat scan and quarantine any infections found. Additionally, check that all apps are fully updated, as outdated software can create vulnerabilities.

If the suspicious connections persist even after malware removal and app updates, the issue could be at the network level. Contact your wifi router manufacturer or internet service provider to report the activity and have them audit network security. As a last resort, back up your smartphone data and perform a factory reset if threats cannot be eliminated. A full wipe will clean out any persistent malware lurking in the system.

Staying vigilant to network activity changes lets you catch and resolve problems before they escalate into compromised accounts or stolen data. Report any lingering suspicious connections even after taking security steps.

FAQs
