The Importance of Multi Factor Authentication

Last month, the RSA had their security conference, and Microsoft shared quite the alarming statistic about user accounts.

They stated that while 95% of users are protected, there’s still 5% that remains compromised. This 5% is what hackers feed upon. And while 5% of users doesn’t seem like a big number, that rounds out to be around 1.2 million logins every month.

Not only that, but Microsoft engineers said that most, if not all, of these risked accounts are not using MFA, or multi-factor authentication. This system allows a lower risk of a possible compromise to your account – which is incredibly important to any personal information you may have stored. For Office 365 users, set up a 2-step verification here.

Using multi-factor authentication is one of the easiest and most effective ways to increase the security of your organization. It’s easier than it sounds – when you log in, multi-factor authentication means you’ll type a code from your phone to get access to Microsoft 365. This can prevent hackers from taking over if they know your password. Multi-factor authentication is also called 2-step verification. Individuals can add 2-step verification to most accounts easily, for example, to their Google or Microsoft accounts.

Tech Support Scam Victims Receive Refunds from FTC

Yesterday, the FTC announced on their website that they will be sending out refunds to those who were victimized by tech support scammers.

In a statement, they wrote, “The FTC, along with State of Connecticut and Commonwealth of Pennsylvania, alleged that the perpetrators of the scheme, which operated under Click4Support and other names, used ads on search engines like Google and popups on websites. The ads and popups claimed to be from major tech companies such as Microsoft and Apple and tricked consumers into calling the defendants and buying tech support services that consumers did not need.”

This operation led to many users’ computers getting infected with viruses and malware. Many of the viruses look legit, as hackers tend to use the brand logos.

The refund total comes to over $1.7 Billion, and will be dispersed through checks or PayPal over the year. The FTC warns consumers that they will never ask you to pay any fee to cash your check. And if you are asked to do so to call Rust Consulting, Inc., at 1-877-389-4472.

Be sure you are handling computer viruses properly by downloading anti-virus software, which can detect and remove harmful trojans or malware. It is beneficial to have even if you’re not concerned about a potential threat. Norton and McAfee are well known anti-virus software subscriptions, available for you to purchase online.

Keeping your OS updated to the latest version is helpful as well, as it contains the protection and security needed.

Someone Hijacked Phorpiex botnet and Uninstalling Their Malware

Late last month, security analysts recognized a hijack of the Phorpiex botnet.

Phorpiex Botnet is a 10 year old network that has spread malware and has affected computers all across the world. And if you have this particular malware on your computer, you may have found a pop-up message saying “Please install AntiVirus Software and update your computer!”

At first, security analysts thought it was a prank by the Phorpiex network. However, they soon realized that the malware was slowly dissipating from those affected.

Though there’s no definite explanation for this, some say that it’s possible another malware network hacked into the Phorpiex system so they would lose funds. Competition seems to heighten in the cyber-criminal world.

To avoid these, and other malware problems on your PC, make sure to keep your operating system up to date and have the latest anti-virus software installed.

Received a Phone Call from Microsoft, Don’t Answer

If you ever receive any phone calls from someone who says they work for Apple, Google, or even Microsoft, just hang up.

While it sounds rude to do, here is why. Cyber hackers are always figuring out ways to scam potential victims. The norm was through e-mails, however they’ve found that calling customers, claiming to be the software/hardware companies, they can dupe those into giving credit card or other personal information over the phone. These people may sound completely legit and may even know what software you’re using.

According to Microsoft Security, “Once cybercriminals gain your trust, they might ask for your user name and password or ask you to go to a legitimate website (such as www.ammyy.com) to install software that will let them access your computer to fix it. Once you do this, your computer and your personal information are vulnerable. “

Here’s the thing to remember: Apple, Google, and Microsoft will never ever call you. If for whatever reason you have issues with your phone, you can easily look on the company’s website for any information regarding particular problems. If that doesn’t work, it’s best for you to reach out to their customer service.

Windows 10 Ransomware E-Mails – Do NOT Download

If you receive an e-mail about installing Windows 10 updates, just delete it. A new ransomware has been found, urging users to install the latest Windows 10 update. The subject line shows either ‘Install Latest Microsoft Windows Update now!’ or ‘Critical Microsoft Windows Update!’ and once opened, a file extension attachment will show up for you to click on.

This malicious download will infect any computer that downloads the “.jpg” file extension. TechRadar reported that the download, “encrypts all of the files on the infected user’s system and appends their filenames with its own file extension, 777. A ransom note with the filename ‘Cyborg_DECRYPT.txt’ is then left on the desktop of the compromised machine. Finally the ransomware leaves a copy of itself called ‘bot.exe’ hidden at the root of the infected drive.”

The file is called ‘bitcoingenerator.exe’ and the GitHub account it’s from is named “misterbtc2020”. This ransomware can lock your PC and your files be encrypted, and for a ransom, you can receive your files as decrypted.

Make sure your antivirus is up to date on your computer to avoid any and all malicious cyber attacks. Also, remember that Windows 10 updates are only pushed through its operating system and not through e-mails.

If you ever have an issue with any Windows 10 updates, give us a call at 1-800-620-5285.  Karls Technology is a nationwide computer service company with offices in many major cities.

Microsoft Office 365 Phishing Scam Hitting Emails

Scammers are at it again. If you open your inbox and notice a Windows 365 e-mails that appear rather genuine, be weary. Many hackers are quick to gain any kind of personal information from your Microsoft and Outlook accounts. They have the brand logos and everything! Companies in the medical field, financial, insurance and many more are being targeted.

According to Bleeping Computer, “The potential victims’ emails are checked against huge lists of validated email addresses before redirecting them to the phishing forms, which allows the crooks to scrape their targets’ company-branded tenant login pages containing custom backgrounds and banner logos, and have them “dynamically inserted into the phishing landing page.”

I checked in my old company e-mail, and though there were none in my inbox, there were a few scams in my Junk folder. And they legitimately looked like it was from Office 365. And yes, I do have an Office 365 account.

Often times, you can click on the sender (in this case, Administrators Team) to see the e-mail it was sent from. However, in my case, I was unable to click on it. Obviously, this particular e-mail being in my Junk folder was the first red flag. The second red flag was that I couldn’t see fully who had sent this.

This scam is still active and doesn’t appear to be stopping anytime soon. Pay attention to the senders’ e-mail address and do not click any links in your Junk folder e-mails. That’s all it takes to get your sensitive information compromised.

Windows PC Warning – Attack Risk

Your Windows PC may be susceptible to an attack by hackers. If your PC Intel processor was made after 2012 and you haven’t updated your system, any personal information may be compromised. The attack can maneuver around security that is used to protect from Spectre and Meltdown exploits.

There was a July Patch this past Tuesday to fix the bug, and Windows and Intel are urging users to update their computers.

ZDNet blogs, “The bug has been called SWAPGSAttack because it exploits SWAPGS, an instruction for x86/x64 CPUs that switches the system to start addressing the protected memory set aside for operating system kernels. Attackers taking advantage of SWAPGSAttack [CVE-2019-1125] could use it to secretly monitor and steal sensitive information from a targeted machine – all without leaving a trace of an attack against the hardware.”

This bug was eventually found by BitDefender and shared their information to help fix the Tuesday’s Patch.
