Hackers look for vulnerabilities that they can exploit.
If you look for the term zero-day attack in your home dictionary, you probably won’t find it.
Go ahead and check…I’ll wait.
You might not even find the term in some online dictionaries (though to be fair, it does appear in others.).
Nevertheless, if you google the term, you’ll find thousands of references to it, many of them from mainstream sources including Forbes, Time, and USA Today. So what’s the deal? If the term is so important, why isn’t in the dictionary yet?
As with so many computer-related terms, the phrase zero-day attack has recently crept into the lexicon of the common person, after being used by technical types for more than a decade. Also known as 0day attacks, zero-hour attacks and 0hour attacks, these are attacks that exploit a vulnerability in a computer application or program.
A vulnerability, by the way, is simply an error in a software that could be exploited. It isn’t a problem in itself, and it isn’t something that stops an application or program from working properly. However, if a vulnerability is discovered by a hacker, and if the hacker uses the vulnerability to conduct nefarious activities, then the moment these nefarious activities are discovered, it is known as a zero-day attack.

Online Privacy, PC security
Your email archive is full of information that’s valuable to you—and to cybercriminals.
The combination of plentiful email storage and relaxed password practices enable criminals to do their worst. Many Web-based email systems now offer multiple gigabytes of storage for free. For example, Google gives you 15GB to share across Gmail, Google Drive, and other Google services. With all that free storage, you may be using your email account as a kind of searchable archive of important data. And you probably don’t delete messages that you might have erased in the past. With gigabytes of storage, why bother? You may need those messages for reference later.

Technology can be defined as applications, instruments, or processes that enhance or simplify the aspects of everyday life. The vehicle you use to drive to work is an example of technology that simplifies life. Or, the Internet, as a whole, can be seen as technology that has greatly enhanced our lives. While the introduction of the Internet led to many benefits, unfortunately, it also came with its own set of problems. Most significantly, these problems can negatively impact your security and privacy.
