Ransomware has been much in the news since the WannaCry attack on May 12, 2017.

The WannaCry ransomware attack was a worldwide cyberattack by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency.

The attack started on Friday, 12 May 2017, and within a day was reported to have infected more than 230,000 computers in over 150 countries. Parts of Britain’s National Health Service (NHS), Spain’s Telefónica, FedEx and Deutsche Bahn were hit, along with many other countries and companies worldwide.

Best practices to guard against such attacks apply to both personal and business computers. In particular, that you keep the Microsoft Windows operating system up-to-date (Windows Update). Also, as mentioned previously, many of these attacks start with hacking your “head” rather than your hardware — your PC — via targeted phishing email messages.

I’ve written about this topic before. In the last few years, I’ve probably seen as much mayhem done on my clients’ PCs by Potentially Unwanted Programs (PUPs) as by computer viruses. In many ways, winding up with PUPs on your PC actually is easier. What can you do? How do you know if you have PUPs?

Malwarebytes Labs Blog recently summarized this topic with an excellent infographic.

… we’ve come up with a PUPs cheat sheet that businesses can use to train IT staff and users. A little PUPs awareness, if you will. Read on to learn more about how you get PUPs, what they do to your computer, and how you can avoid them.

The PUP category includes spyware, adware, bundleware, junkware. Aggressive marketing is used by both legitimate companies and malicious organizations. Here’re some signs that you’ve got PUPs:

  • Your PC slows down
  • Out of the blue annoying ads or promotions pop up
  • Extra toolbars are added to your web browser
  • Unusual requests for private information pop up

The most common way to get PUPs is by not paying close enough attention during installation of programs, especially so-called free programs; and miss pre-checked tiny checkboxes opting you in to extras. Such presumption is like a contract with lots of fine print that you’re pushed to sign without adequate examination. Whose fault is that, eh?

Malwarebytes has done a great job characterizing these “bad behaviors” as advertising infractions, download infractions, and web infractions. The end result is a set of criteria and a database of blacklisted programs used in their Malwarebytes Anti-Malware (MWB) program. Using MWB is an industry best practice.
