New Year’s Resolutions for Your Computer

Running the Best Security Software

Most computers today run at least some form of basic antivirus.  In the modern day however, threats have evolved to be more sophisticated, more damaging, and much more common.   Ransomware, malware, phishing, and zero-day attacks all work to attack unpatched systems without strong security.
Today, to keep up with increasing threats, you need a supplemental AV to add to Windows Defender.  A layered system means more than just virus scanning.  A comprehensive security package includes prevention, detection, and system monitoring at a minimum.   These layers work together to provide security many times stronger than a stand-alone system.

Reliable, up-to-date, security keeps you safe online.  It’s a resolution you simply can’t afford to skip.

Clean Up Files

Cleaning up unnecessary files is the number one way to gain additional storage space on a typical device.  It’s cost-effective without any extra hardware purchases.

Almost all computers have files hanging around from old software, data or applications they no longer need.  Just like tidying the spare room or de-cluttering the kitchen, clearing files off your desktop and organizing your emails will leave your computer feeling refreshed and new again.

Restart Your Computer

Fully shutting down a computer and rebooting can take time.  When you are watching the clock, waiting to start a task or get work done, it can feel like an eternity.  Most of us enjoy simply opening the lid or powering on the screen to have everything ready to run.

At times, a computer may not be fully restarted in weeks or even months.  Our poor habits can cause issues with running software and the operating system too. Hardware updates, security patches, and critical updates often wait for a reboot before they install.  Waiting too long can leave security flaws open and the system vulnerable to attack.

Merely performing a reboot every once in a while (we recommend weekly) can secure your system and help get rid of software problems.  Often updates prevent new issues from cropping up too.

Special Note: Just shutting down a computer using the shutdown button does not accomplish the same thing as a RESTART..

Keep Your Computer Away from Dust

Dust, hair, and household debris are one of the major causes of premature death for computers.  Fans, used to cool components, suck in house dust as well as the air they need.  This dust often clogs up the inside of the device and overheats internal components.

If possible, keep a tower PC off the carpet, don’t run your laptop sitting on the floor, blanket, or soft furnishings.  Cleaning out your device is as good a resolution as any, and there’s never a better time than now.

Computer Repair San Antonio-Should You Repair, Upgrade, or Replace Your Computer?

Should You Repair, Upgrade, or Replace Your Computer?

Like many valuable things we buy, new computers suffer from wear and tear over time.  Our computers are particularly vulnerable as we have placed more and more demands on them every year.  New machines have got faster, quieter, more reliable, and more capable over time. At the same time our own computers have begun to slow and sometimes even stop performing altogether.
There are many ways to address the problem of a PC which isn’t quite performing up to the task anymore.  Whether frustratingly slow or no longer working; we are happy to take a look. When you bring your computer to us we will diagnose the condition and find a solution that works for you. Often times the simplest solution works best.  A complex problem sometimes only needs a simple repair to get your home computer up and running like new again.  Whether a small replacement part, loose wire, or bad connection; we will find and fix the problem to give your familiar, home machine a new lease of life.

Many computers come to us running slowly, taking a long time to start up, or freezing when trying to load files and programs.  Often owners have reached a breaking point and become convinced the machine is fit for only the scrap heap. In many cases, the problem can be pinpointed to a bottleneck in the system.  A single, seemingly trivial,  part can be holding up the entire system. Amazingly, upgrading just that one component can make the whole machine run like new again.

Adding memory can allow programs to run faster.  Adding an updated, faster hard drive can allow files to be retrieved without delay.  In both cases, a low-cost single component can provide a cost-effective solution that makes an old machine like new again.

In some cases, computers succumb to more major faults.  A critical part, difficult to replace, may stop working altogether. A failure of the motherboard for example, the backbone that all other components connect to can be expensive, if not impossible, to fix.  Typically, with the fast-paced and ever-changing nature of computing, a motherboard will only house computer parts that were manufactured around a similar time.

A motherboard is almost certain to be incompatible with components built just a couple of years before or after its own design for example. Occasionally even a motherboard failure can be resolved too.  In these cases we strive, whenever possible, to find a replacement board of the same generation that will work alongside existing components.  The result is a cost-effective solution that keeps cost down by saving replacement parts.

In cases where a like-for-like replacement motherboard is not available, many parts of the computer may have to be replaced at the same time.  Often replacement costs in these cases can get close to, or even exceed the cost of buying a new machine.

We would always give advice where it makes sense financially and practically to consider replacing an old machine. Often, in this respect, a home PC can be considered a little like a car.  Sometimes a simple, non-expensive, easy to replace component such as the window wiper can fail.  While a crucial part to be used for driving; it would be silly to suggest replacing the vehicle once it has worn out.

A window wiper may be low-cost and simple to replace, but if the engine were to wear down or break the solution may not be quite as simple. Attempting to make a 30-year-old car as fast, safe, and reliable as a brand new model generally doesn’t make any financial or practical sense.  Sometimes the best course of action to save money and avoid breakdowns is a more up to date vehicle.

In computing, many of the same rules hold true.  The best solution in each case is always tailored personally to fit you and your own computer.

Give us a call us at 210-549-6477 to discuss your computer issues.  We’ll keep you informed about your machine and advise on the best course of action to get you up and running as quickly as possible.

Can I Just Unplug My Computer to Shut It Down?

You may damage your computer.

By pulling the plug or forcing a power-off by holding down the power button, you risk corrupting data on your hard drive and damaging hardware.

I’m not sure what kinds of problems you’re having with the power button, but even that needs to be used correctly, or you could end up with the very problems you’re seeing.

All You Need to Know About the WannaCrypt Ransomware

by

WannaCrypt is a ransomware program targeting Windows. On Friday, 12 May 2017, a large cyber-attack using it was launched, infecting more than 230,000 computers in 150 countries, demanding ransom payments in the cryptocurrency bitcoin in 28 languages.

 

It was being spread primarily by phishing emails (most commonly links or attachments) and as a worm on unpatched systems.

The attack affected Telefónica and several other large companies in Spain, as well as parts of Britain’s National Health Service, FedEx, Deutsche Bahn and LATAM Airlines. Other targets in at least 99 countries were also reported to have been attacked around the same time.

WannaCry is believed to use the EternalBlue exploit, which was developed by the U.S. National Security Agency (NSA) to attack computers running Microsoft Windows operating systems. Although a patch to remove the underlying vulnerability for supported systems (Windows Vista and later operating systems) had been issued on 14 March 2017, delays in applying security updates and lack of support by Microsoft of legacy versions of Windows left many users vulnerable. Due to the scale of the attack, to deal with the unsupported Windows systems and to contain the spread of the ransomware, Microsoft has taken the unusual step of releasing updates for all older unsupported operating systems from Windows XP onwards.

Shortly after the attack began, a researcher found an effective kill switch, which prevented many new infections and allowed time to patch systems. This significantly slowed the spread. It was later reported that new versions that lack the kill switch were detected. Cyber security experts also warn of a second wave of the attack due to such variants and the beginning of the new workweek.

As always, be sure your Windows is up to date. XP users should consider upgrading where possible. The vulnerabilities for that operating system will not go away. Don’t click links in an email. Don’t open file attachments.

And, our longest running advice; back up regularly. You can back up to the cloud, or another drive. Programs like Macrium Reflect can Image your drive essentially restoring everything at any time.

Animated Map of How Tens of Thousands of Computers Were Infected With Ransomware

Malwarebytes www.malwarebytes.com

Dear ,

A massive ransomware attack spread across the globe today, locking up thousands of hospital, telecommunications, and utilities systems in nearly 100 countries. The attack used data stolen from the NSA to exploit vulnerabilities in Microsoft Windows and deliver the WanaCrypt0r ransomware. The demand was for $300 per PC.

While the ransomware was first detected wreaking havoc in emergency rooms and doctors’ offices in the UK, the infection quickly spread worldwide, including to the US.

We’re alerting you to reassure you that if you’re currently using the premium version (or the premium trial) of Malwarebytes with real-time protection turned on, you are protected from this threat. Our premium technology blocks the WanaCrypt0r ransomware before it can encrypt your files. (The free version of Malwarebytes, however, does not protect you against WanaCrypt0r. To see which version you have, open up your Malwarebytes software and look for the version name at the top of the window.) Learn more about Malwarebytes

If you’re not currently using the premium version of Malwarebytes, we recommend that you update your Microsoft Windows software immediately. Microsoft released a patch for this vulnerability in March, but many users haven’t updated, leaving their computers open to this attack.

Here at Malwarebytes, we pledge to keep you protected and informed about the latest issues. Your peace of mind is our number one priority.

Sincerely,

The Malwarebytes team
P.S. Learn more about this threat here.

Massive Global Ransomware Attack Underway, Patch Available

by

This is a public service security announcement for all users of computers running any version of Windows.

We have confirmed that a serious virulent ransomware threat known as WannaCrypt0r/WannaCry has affected Windows computers on shared networks in at least 74 countries worldwide, with 57,000 reported individual cases being affected. And according to the analysis team at Kaspersky Lab, that number is growing fast.

Once one computer on a network is affected, the malware infection easily spreads to other Windows computers on the same network, shutting down entire government agencies and national infrastructure companies. Hospitals across the UK were being forced to divert patients and ambulance routes as of Friday afternoon, and several utility companies across Europe reported infection across their computer networks according to BBC News.

What Is Ransomware?

Ransomware is a kind of malicious script or software that installs itself on your computer without your knowledge. Once it’s installed and running, it will lock down your system and won’t allow you to access any files or programs on that computer. Usually, as in this current WannaCry exploit, it will alert you to the lockdown with an impossible-to-ignore pop-up screen which informs you that your computer is being held for ransom. To unlock your system and regain access to the computer being held hostage, the lock screen informs you that you must purchase an unlock tool or decryption key from the hacker.

Where Did This Threat Originate?

In this case, Microsoft has been aware of the vulnerability since March 2017, when it published a Security Bulletin covering the potential risk. According to the Spanish newspaper El Mundo, early indicators seem to point to the attack originating in China, but more information is needed.

How Can You Tell If Your Computer Is Infected?

The most obvious way to tell if your computer has been affected is if you are seeing a ransomware pop-up screen when you start up your computer. But because we don’t know how long the malware sits on your computer or network, not seeing this pop-up isn’t necessarily an indication that you haven’t been infected. The bottom line: if your Windows computer has connected to a shared network, such as those found in schools, public places, cafes and businesses, and you don’t have complete control over every computer on that network and haven’t been keeping Windows up-to-date, your computer may be infected.

How to Protect Yourself From the Vulnerability

According to Microsoft a fix for this vulnerability was released on March 14th for all affected versions of Windows. If you are running Windows and have automatic updates enabled you should be okay. If you don’t and haven’t updated recently you should update to the most recently released version immediately. It is important to note that unsupported versions of Windows, like XP, did not receive this security update. Those systems should either be isolated or shut down.

Please pass this along to your friends and family. Those that are less technical may not have updates auto-enabled, and may need a helping hand updating their operating system.

Massive Ransomware attack going worldwide.

Massive Ransomware Outbreak

We have an update on this outbreak here. The ransomware is using an NSA exploit leaked by The Shadow Brokers, and has made tens of thousands of victims worldwide, including the Russian Interior Ministry, Chinese universities, Hungarian telcos, FedEx branches, and more. Original article below.

A ransomware outbreak is wreaking havoc all over the world, but especially in Spain, where Telefonica — one of the country’s biggest telecommunications companies — has fallen victim, and its IT staff is desperately telling employees to shut down computers and VPN connections in order to limit the ransomware’s reach.

The culprit for these attacks is v2.0 of the WCry ransomware, also known as WannaCry or WanaCrypt0r ransomware. For those affected, you can discuss this ransomware and receive support in the dedicated WanaCrypt0r & Wana Decrypt0r Help & Support Topic.

WCry ransomware explodes in massive distribution wave

Version 1.0 of this ransomware was discovered by Malwarebytes researcher S!Ri on February 10 and then spotted in a brief campaign on March 25 by GData security researcher Karsten Hahn.

Version 2.0 was detected for the first time around four hours ago by independent security researcher MalwareHunter. The security researcher says the ransomware came out of nowhere and started spreading like wildfire.

In these first four hours, WCry 2.0 made more victims than Jaff, a ransomware spotted this week distributed via the Necurs botnet, the former home of the Locky ransomware. In numbers, in just four hours WCry made 1.5 times more victims than Jaff did all week.

Currently, researchers weren’t able to pinpoint the exact origin of the WCry distribution campaign. At the moment, it could be from malvertising, exploit kits, email spam, or hand-cranked RDP attacks.

Windows Defender tops AV-Test zero-day malware charts for the 3rd straight month

April 3, 2017

The recent test reports of Security firm AV-Test reveal that Microsoft’s Windows Defender has scored 100% for the 3rd consecutive month when tested for the zero-day malware protection. AV-test tested Windows Defender against current online threats, which involved accessing known malicious websites or e-mails so as to test if the security product is able to ward off attacks practically or not.

AV-TEST Product Review and Certification Report tests for Windows 7 (January and February 2017) and Windows 10 (December 2016) show Microsoft doing a great job and scoring 100% in zero-day malware checks. Here is the analysis.

Windows Defender does a good job for Windows 10 & Windows 7

Not long ago, Windows Defender was so mediocre that it was only considered as the baseline metric in third-party tests. However, analysis of the recent AV-test reports will tell you that Windows Defender has improved significantly in the past 12 months.

For instance, let’s compare the AV-test report for Windows 7, for zero-day malware protection in the past 12 months. In July and August 2016, the Windows Defender scored 95.2% and 86.1% respectively while for the same test conducted this year in January and February, it scored a perfect 100%.

 

Analyzing the results of the third-party suites, some of which charge you money to use them, the likes of AVG Antivirus Business 16, G Data Antivirus Business 14, Intel Security McAfee Endpoint Security 10.2, Seqrite Endpoint Security 17.0 were found to be trailing Microsoft.

On the other hand, Bitdefender Endpoint Security 6.2, F-Secure Client Security 12.30, Kaspersky Lab Endpoint Security 10.2, Kaspersky Lab Small Office Security 10.2, Sophos Endpoint Security and Control 10.6, Symantec Endpoint Protection 14, Symantec Endpoint Protection Cloud 22.8 and Trend Micro Office Scan 12.0 were found as effective as Windows Defender, all scoring 100%.

For Windows 10 users

Comparing the AV-test report for Windows 10, for zero-day malware protection in the past 12 months. Back in March and April 2015, the Windows defender scored a poor 88.9% and 88% respectively. Whereas, in November and December 2016, it scored 97.9% and 100% respectively showing a remarkable improvement.

Third-party suites like AVG Antivirus Business 2016, Bitdefender Endpoint Security 6.2, G Data AntiVirus Business 14 and Intel Security McAfee Endpoint Security 10.2 were found to be less effective dealing with zero-day malware protection when compared with the Windows Defender.

While, F-Secure Client Security 12.2, Kaspersky Lab Endpoint Security 10, Kaspersky Lab Small Office Security 5, Seqrite Endpoint Security 17, Sophos Endpoint Security and Control 10.6, Symantec Endpoint Protection 14 and Trend Micro Office Scan 11 were at par with the Windows Defender, all scoring 100%.

Can you consider Windows Defender against top third-party antivirus suites

The results from the AV-tests shows that Windows Defender has improved a great deal in moving from the lower bottom levels in the last 6-12 months. Although it has still more ground to cover before it can challenge the top security vendors who offer a better overall protection, you can surely rely on Defender to provide more than average class protection.

Chrome and Firefox Phishing Attack Uses Domains Identical to Known Safe Sites

This entry was posted in General Security on April 14, 2017 by Mark Maunder   62 Replies

This is a Wordfence public service security announcement for all users of Chrome and Firefox web browsers: 

There is a phishing attack that is receiving much attention today in the security community.

As a reminder: A phishing attack is when an attacker sends you an email that contains a link to a malicious website. You click on the link because it appears to be trusted. Merely visiting the website may infect your computer or you may be tricked into signing into the malicious site with credentials from a site you trust. The attacker then has access to your username, password and any other sensitive information they can trick you into providing.

This variant of a phishing attack uses unicode to register domains that look identical to real domains. These fake domains can be used in phishing attacks to fool users into signing into a fake website, thereby handing over their login credentials to an attacker.
