Ransomware has been spreading like wildfire over the past few years, but up until very recently, Mac users were spared from this troubling development. Now, security researchers at Palo Alto Networks have discovered what they believe to be the first instance of completed ransomware on an Apple device. As this threat is “in the wild,” Mac users should be wary of it and see it as a potential threat.

Small and medium-sized businesses continue to have problems shoring up their cyber security. Even with the latest solutions, like antivirus and firewalls, they still need to be wary of impending attacks. New threats are created on a daily basis, all of which want to infiltrate your network and cause harm to your business. In fact, 27.3 percent of all malware in the world was created in 2015 alone. Will we ever escape from the clutches of malware?

There’s an intrusive malware on the Internet that locks a user out of their PC and directs them to a fake IT support phone number. In addition to being inconvenient, it can lead to the theft of sensitive information. If this happens to you, whatever you do, don’t call the fake phone number.

As mentioned, there are other types of malware that target ATMs almost exclusively, including a backdoor called Ploutus. Just like GreenDispenser, Ploutus originated in Mexico, and allowed criminals to steal money from ATMs by sending commands through the PIN pad or through a keyboard. Later versions allowed hackers to send a text message to the ATM to distribute cash. While this ATM malware originated in Mexico, it’s suggested by Ploutus’s English localization that it was designed for use in other countries.

With many organizations heavily relying on mobile computing, malicious operators have begun targeting the “low-lying fruit” of a business’ IT infrastructure, which is often a company’s mobile devices. Kemoge, a malicious adware strain designed to corrupt Android mobile operating systems, is the latest mobile threat that your business needs to protect itself against.

Ransomware is one of the most devastating computer viruses in today’s computing landscape. You may have heard of one of its most famous variations, Cryptolocker. It received a lot of attention when it dramatically hit the scene two short years ago. Thankfully, the threat from CryptoLocker has decreased after the GameOver Zeus botnet was taken down last year. Although, now we’ve got a new, more contagious strain of this ransomware to deal with known as Cryptowall.

If you feel that there’s an increase in ransomware activity, don’t worry; it’s not just you. Hackers are now taking greater advantage of ransomware, a threat that locks down files and returns them in exchange for a payment. This is wreaking havoc on the computing world. Even the FBI has acknowledged the threat, and has issued a warning that the most likely type of cyber extortion users will encounter is probably going to be DDoS attacks.

The Internet is up to its ears with threats and hackers, but some of the most annoying malicious entities are bots. These are systems which can gather information from all kinds of sources. While some aren’t malicious in nature (think SEO bots which gather data from websites), there are those that aren’t so innocent. These tend to fall into the hands of hackers and attempt to steal information or send spam.

Grab your tissues, it’s flu season! Just like biological viruses such as the flu can cripple an entire office, digital viruses can cause a lot of trouble for businesses too. Both downtime-causing virus scenarios can be prevented if proper safety measures are followed, like sanitation and cybersecurity.

The latest threats can put a damper on your business plan and put your company at risk. Therefore, it's only natural to protect yourself from them. This new threat in particular, Cryptowall 2.0, has the potential to do plenty of heavy-duty damage to your business's network, if given the opportunity.

We reported in August that security researcher Karsten Nohl of SR Labs revealed a flaw in USB firmware that cripples the technology beyond repair. At the Black Hat security conference, it was revealed that USB devices of all kinds can be targeted by hidden malware. Nohl refused to release the code used in the research, due to being concerned that it would be used by the wrong hands, but it has been made public anyway, putting the masses at risk.

A new malicious threat in the technical marketplace has just been discovered. The bug, dubbed the Bash bug, or "shellshock," is on the loose for users of Unix-based operating systems, like Linux or Mac OS X. It allows the execution of arbitrary code on affected systems, and could potentially be very dangerous for your business. In fact, CNet is calling it "bigger than Heartbleed."

In today’s society, we throw the word “hack,” around without a second thought. This is especially true in the realm of cyber security for businesses. Have you ever taken a moment to think about why the term “hacker” was chosen as the title for those who partake in sketchy online activity? What exactly makes a hacker, a hacker?

One would assume that software preinstalled on a new PC is secure and has been properly vetted by the manufacturer. This is the case 99 percent of the time, but an exception has recently been discovered with the Superfish app, which came installed on new Lenovo computers sold between September and December of 2014. How can you protect your PC from this fishy security threat?

USB devices have long been a staple of the technology world, but are notoriously vulnerable to exploitation from hackers and malware. As malware grows more and more sophisticated, you can no longer trust simple antivirus scans to protect your business.

It has been two weeks since the National Communications Association warned the world about the GameOver Zeus and Cryptolocker ransomware, and if you haven't taken steps to avoid these threats, it's not too late - if you haven't been infected yet, do so as soon as possible. Otherwise, your network will be vulnerable, and so will your banking credentials.

A new botnet threat could spell "game over" for unaware Windows users - the threat targets almost all versions of Windows and Windows Server (excluding Windows 8.1). Even though the Department of Homeland Security, Federal Bureau of Investigation, and Department of Justice have disrupted it, users are still at risk. Thankfully, they still have time - two weeks, until the threat returns.
