WhatsApp recently announced that it has patched a software vulnerability that was being used by unknown hackers to target specific users of Apple products and hack them with spyware. In an advisory, WhatsApp said that a previously unknown bug “may have been exploited in a sophisticated attack against specific targeted users.” WhatsApp fixed the bug while last week, Apple fixed another bug, known as CVE-2025-43300. Together, these vulnerabilities appear to have been the weak spots that allowed malicious spyware attacks targeting specific. The spyware aims to steal users' data.
So, how do you know if your phone has been compromised? Often, a phone hack isn't announced with a flashing red light. Instead, it manifests through a series of subtle, yet concerning, changes in your phone's behavior. One of the first indicators of a potential hack is unusual phone behavior . This isn't always obvious, and sometimes it can be dismissed as a minor glitch. However, consistent and unexplained anomalies should raise a red flag. Understanding these indicators is the first step towards recognizing a potential breach.
Unusual Battery Drain: One of the most common signs of a compromised phone is a rapidly draining battery. Malware or spyware running in the background constantly consumes power, even when you're not actively using your device. If your phone that once lasted all day now struggles to make it past lunch, it's worth investigating.
Increased Data Usage: Similar to battery drain, unexpected spikes in data usage can point to a hack. Malicious software often communicates with external servers, sending out your data or receiving instructions. Check your phone's data usage statistics regularly. If you notice a significant increase without a corresponding change in your habits, be suspicious.
Slow Performance and Frequent Crashes: A hacked phone can become noticeably sluggish. Apps might take longer to open, your phone could freeze frequently, or it might spontaneously restart. This is often due to the malicious software consuming your phone's processing power and memory.
Strange Pop-ups and Ads: While some apps legitimately display ads, an abundance of unsolicited pop-up ads, especially when you're not even browsing the internet, can be a strong indicator of adware or spyware. These ads might also redirect you to suspicious websites.
Unfamiliar Apps: Regularly review the apps installed on your phone. If you discover apps you don't recognize or remember installing, delete them immediately. Some sophisticated malware can even disguise itself as legitimate system applications.
Overheating: A phone working overtime due to hidden processes can generate excessive heat, even when it's idle. If your phone feels unusually warm to the touch without heavy usage, it could be a warning sign.
Unusual Messages or Calls: Be wary of text messages or calls from unknown numbers that seem out of place. Phishing attempts often start this way, trying to trick you into clicking malicious links or revealing personal information. If friends or family report receiving strange messages or calls from your number that you didn't send, your phone might be compromised.
Changes to Settings You Didn't Make: If you notice changes to your phone's settings, such as your homepage being altered, new browser extensions appearing, or security settings being lowered, without your input, it's a red flag.
