Introduction: IoT Manufacturers Favor Convenience over Security Because IoT security is still an afterthought, cybercriminals in general consider smart devices a “low-hanging fruit” – a target easy to compromise and manipulate. Security (and privacy) by design is key for IoT, and probably the only effective way for a smart gadget to protect its communications is […]

Introduction: In the previous article of this series, we discussed how format string vulnerabilities can be exploited. This article provides a case study of how format string vulnerabilities can be used to exploit serious vulnerabilities such as Buffer Overflows. We will begin by understanding what stack canaries are and then we will exploit a Buffer […]

Fuzzing is a black-box software testing technique and consists of finding implementation flaws and bugs by using malformed/semi-malformed payloads via automation. Fuzzing an application is not a matter of simply exploiting a specific point of an application, but also acquiring knowledge and potential crashes that could be explored in-depth through the implementation of crafted payloads […]

Copy-paste compromises: Introduction and overview Although the concept of copy-paste compromises is not exactly new, there are now several different forms of the attack. In the version of copy-paste compromise that we’ll discuss today, malicious actors use open-source or publicly available exploit code, web shells and other tools to gain information. Recently, Australia has revealed […]

Something’s not right. Maybe your phone is losing its charge way too quickly. Or one day it suddenly starts turning itself off and on again. Perhaps it’s running hot, so hot it’s hard to hold. Likewise, you might see outgoing calls that you never dialed or strange spikes in your data usage. Signs like these could mean that your smartphone’s been hacked. Learn how to protect your smartphone with McAfee Mobile Security
Several signs of a potential smartphone hack can look like a technical issue, at least on the surface. Yet the fact is that these issues may be a symptom of a deeper problem, such as malware installed on your smartphone. Malware can eat up system resources or conflict with other apps and your operating system, all of which can cause your phone to act sluggish or erratically.
Yet, in a way, that’s good news. Because malware can run inefficiently on your phone and create hiccups both large and small, it can tip you off to its presence. And with all the important information we carry in the palms of our hands nowadays, that’s good news twice over. Knowing the signs, subtle or otherwise can alert you to an otherwise largely invisible problem.
Whether hackers physically sneak it onto your phone or by tricking you into installing it via a phony app, a sketchy website, or a phishing attack, hacking software can create problems for you in a couple of ways:
Some possible signs of hacking software on your phone include:
Maybe you’ve seen some of the signs we mentioned earlier. Is your device operating slower, are web pages and apps harder to load, or does your battery never seem to keep a charge? These are all signs that you could have malware running in the background, zapping your phone’s resources.
Like the performance issues above, malware or mining apps running in the background can burn extra computing power (and data). Aside from sapping performance, malware and mining apps can cause your phone to run hot or even overheat.
If you find apps you haven’t downloaded, or calls, texts, and emails that you didn’t send, that’s a red flag. A hacker may have hijacked your phone to send premium-rate calls or messages or to spread malware to your contacts. Similarly, if you see spikes in your data usage, that could be a sign of a hack as well.
Malware can also be behind spammy pop-ups, changes to your home screen, or bookmarks to suspicious websites. In fact, if you see any configuration changes you didn’t personally make, this is another big clue that your smartphone has been hacked.
While there are several ways a hacker can get into your phone and steal personal and critical information, here are a few tips to keep that from happening:
