Lest you think that hacking is only a Windows problem, Mac users, be assured—you are not immune. In , Apple publicly confirmed that yes, Macs get malware. Previous to that admission, in there was a phishing campaign targeting Mac users , mostly in Europe. Conveyed by a Trojan that was signed with a valid Apple developer certificate, the hack phished for credentials by throwing up a full-screen alert claiming that there's an essential OS X update waiting to be installed.

If the hack succeeded, the attackers gained complete access to all of the victim's communication, allowing them to eavesdrop on all web browsing, even if it's an HTTPS connection with the lock icon.

In addition to social engineering hacks on Macs, the occasional hardware flaw can also create vulnerabilities, as was the case with the so-called Meltdown and Spectre flaws that The Guardian reported in early Apple responded by developing protections against the flaw, but advised customers to download software only from trusted sources such as its iOS and Mac App Stores to help prevent hackers from being able to use the processor vulnerabilities.

And then there was the insidious Calisto , a variant of the Proton Mac malware that operated in the wild for two years before being discovered in July It was buried in a fake Mac cybersecurity installer, and, among other functions, collected usernames and passwords.

From viruses to malware to security flaws, hackers have created an extensive toolkit to wreak hacker havoc on your Mac. A good Mac antivirus and anti-malware program will help defend your Mac against such malware.

For criminal-minded hackers, business is booming. Ransomware attacks on major businesses have been featured heavily in the news throughout Some of these have been high-profile, such as the attacks on the Colonial Pipeline, JBS the world's largest meatpacker , or the large ferry service Steamship Authority. There are a number of ransomware gangs, Ransomware-as-a-Service providers, and types of ransomware out in the wild.

You may be familiar with names like Conti , Ryuk , or GandCrab , for example. Trojans remain a threat to businesses, with some of the most well-known being Emotet and TrickBot. Emotet, Trickbot, and GandCrab all rely on malspam as their primary vector of infection. These malicious spam emails, disguised as familiar brands, trick your end users into clicking malicious download links or opening an attachment loaded with malware. In an interesting twist, Emotet has evolved from being a banking Trojan in its own right into a tool for delivering other malware, including other banking Trojans like Trickbot.

GandCrab is just as awful. In light of the ransomware and Trojan attacks currently favored by criminal hackers, the question now is: how can I protect my business from hacking?

The people who engage in hacking are commonly referred to as hackers. Over the years, hackers have become a staple of popular culture.

However, the usual portrayal of hackers as self-taught, thrill-seeking programming geniuses is not only stereotypical but also greatly exaggerated. Hackers can also break into computers and systems using social engineering, a set of psychological tactics designed to trick an unsuspecting target into giving hackers access to their data. In addition to fun and thrill, hackers can be motivated by numerous other factors.

These include financial gain, theft of personal data, access to confidential information, the desire to take down websites, as well as idealism and political activism. While some forms of hacking are completely legal, most of them are not and are considered criminal offenses.

Ethical hackers use pretty much the same methods as all other hackers, but they always do it with permission from the owner of the system.

Method 1. Log into Windows using an account with administrator access. If you can log into Windows with an administrator account, you can easily change the passwords of any other account. If you are locked out of Windows or don't have access to an administrator account, see the next section. Open the Command Prompt as an administrator. You'll need to do this even if you're already logged in with an account that has administrator access.

Windows 7 and earlier - Open the Start menu, right-click on "Command Prompt," and select "Run as administrator. This will display a list of user accounts on the computer. The accounts will be listed in columns based on their permissions level. You will be prompted to create a new password for username. Enter the new password. You will have to enter the password twice to confirm it. The new password will take effect immediately. Log in with the new password. You can use the password you just created to log into that user's account.

Log out of your current session and log in with the new password. Method 2. Find or create a Windows installation disc. If you don't have access to any administrator accounts on the computer, you can use a Windows installation disc as a workaround.

This requires the same version disc for the version of Windows you are trying to access. The disc doesn't have to be the one that came with the computer. Insert the disc or drive in the computer you want to access. You'll be using the installation disc to access the administrator controls to change users' passwords. The key varies by manufacturer, and will be displayed on the boot-up logo screen. Common keys include: F2 , F10 , F11 , and Del.

Windows 8 and later - Open the Start menu or Screen and right-click the Power button. Open the BOOT menu. Select your installation disc or USB drive as the primary boot device.

The exact process will vary, but generally you'll just reassign the numbers so that the computer boots from the disc or USB drive before the hard drive.
