Friday may have been April Fool’s Day, but there’s no laughing when it comes to what goes on in the ever-changing world of cybersecurity. While much of the country has been focused over the past couple of months on the tax industry’s ongoing woes with identity theft and tax fraud, a number of important yet smaller-scale security issues have come up. To help you stay in the know, we’ve highlighted the most urgent of these stories and explained how you can protect yourself.

Android users are still vulnerable to the Stagefright bug

The exploit that was dubbed the Stagefright bug was a source of some panic when its existence was discovered last July. Many Android device manufacturers rolled out patches and updates to try and protect consumers from any attempted hacking attacks using the exploit, and it’s likely most people forgot about the threat. Unfortunately, it is still something to be concerned about, as researchers at cybersecurity firm NorthBit proved when they developed a version of the bug that could be successfully used to infiltrate phones. According to NorthBit’s report, Nexus 5 phones and older phones running outdated versions of Android are most vulnerable, but it could also affect other phones like the LG G4 and Samsung Galaxy S5.

How can you protect yourself? It’s important to realize that these tests were all done in a controlled laboratory environment, and so far no actual consumers have been affected. However, this is a reminder to all of us that just because a story disappears from the headlines doesn’t mean it has vanished altogether. The tips we provided in our post about the bug are still relevant, and taking care to utilize mobile security options in general as well as update your apps and devices regularly is a good way to ensure you protect your data. Androids that have updated to Android Marshmallow 6.0 or other software that have been patched against the Stagefright bug shouldn’t have anything to worry about.

Ransomware attacks are targeting hospitals across the country

Numerous hospitals, from Kentucky to Washington D.C., have been the targets of ransomware attacks in recent weeks. These medical facilities are exceptionally vulnerable to this kind of attack due to the crucial importance of having access to their data — it’s not exactly a simple matter of cutting their losses in the event a hacker locks doctors, nurses and admins out of files containing vital patient information. Unfortunately, many hospitals are using outdated systems that are easy to hack, making them sitting ducks for ransomware attackers to take out one by one. Many hospitals have had no choice but to pay the ransom, even though that doesn’t always guarantee that file and system access will be regained.

How can you protect yourself? Unfortunately, this is the kind of situation that is out of the hands of the business being attacked — the hospital — as well as the customers (or patients) caught in the crossfire. As we detailed recently, ransomware is a particularly insidious form of malware that locks up files or systems, preventing access unless a ransom is paid to the attacker. While some ransomware has been foiled by security experts, new versions are being created all the time, and some of it is considered uncrackable. The healthcare industry in general is vulnerable to cyberattacks — meaning it’s important for you as a patient to protect your data and pay attention to who has your information as well as what the facility’s data privacy policy is.

Smart cars are at risk of being hacked, says the FBI

Most cars these days are connected to the Internet in some way, as the Internet of Things culture continues to expand to virtually every realm of life. Unfortunately, as the FBI is now warning, this is making modern cars increasingly at risk of being hacked and taken over by criminals. A joint statement released by the bureau along with the Department of Transportation and the National Highway Traffic Safety Administration outlines the dangers posed by software vulnerabilities. The possibilities are endless — and many quite dangerous, such as shutting off the engine and locking the brakes while the car is moving.

How can you protect yourself? The FBI urges vehicle owners to pay attention to any recall announcements, such as the recall Fiat issued last July due to a software glitch that allowed hackers to take remote control of the car. It also suggests taking care to install updates as soon as they are available and be wary of connecting third-party devices like tablets and MP3 players. It’s also important to safeguard any accounts connected to your car’s operation, such as an email address or your phone if you use an app for remote startup, and use strong passwords to protect such accounts.
