How does Wannacry Affect my Computer? As the name suggests, Wannacry is a malware virus. It’s been around for a few years but it’s still increasing in popularity with each passing month. Wannacry is a highly infectious malware worm which spreads quickly across many computer systems during May of this year. Once infecting a Windows computer, it infects the PC’s main hard drive, rendering them all useless for the user and demanding a large ransom payment from the user in exchange for the decryption keys to their files.
This infection typically comes via emails which have either been phished or scammed. It usually begins by installing an email attachment such as an infected download or game update, or even an email which contains an actual email attachment such as an invoice. From there, the worm makes it through the various Windows security settings and infects the system. Unlike typical malware, Wannacry has a number of traits that allow it to infect a computer quickly and reliably. These include:
EternalBlue exploit – The worm makes use of EternalBlue vulnerability to compromise the affected machine. This is a software issue, which allows hackers to bypass typical security measures such as firewalls and antivirus programs. The EternalBlue vulnerability is present both in older versions of Windows and Windows Vista. It attacks an inner layer of Windows called the “Data Object Access Interface”, which is continually referenced by the programs & processes it controls. If an attacker can get control of this Interface, he can then gain unauthorized access to the infected computer. This makes it very difficult to detect and remove.
Server exploit – This is the most common and prolific of all the ways how does wannacry infection occur. Viruses make their way into a working server via infected downloads, email attachments, game demos, and from internet browser vulnerabilities. Once on a computer, the worms can continue the attack even if the user’s security program is constantly running.
How Does Wannacry Infect?
One of the latest attacks against the windows family of programs, the EternalBlue worm has gained popularity because of its ability to attack and attach itself to a variety of executable files. Unlike typical viruses that infect specific applications or files, EternalBlue works across an entire Windows platform. This means that if you have an unpatched Windows system, the worm is capable of executing continuously, without any type of noticeable effect. In addition, it has been known to execute in a matter of minutes once on a PC as opposed to several hours or days once on a properly patched machine. Since many people are unaware that automatic updates are available for nearly every piece of software in today’s market, this is yet another reason how does wannacry infect your system.
A recent patch by Microsoft has thwarted the majority of these worm infections which were taking place. However, the latest patch by Microsoft only addressed the newest versions of Adobe Flash, Adobe Acrobat Reader, and Adobe Reader. Thus, wannacry exploited even older versions of these programs and began to launch another attack on Windows systems. The worm then spread to hundreds of thousands of computers before being killed off by an updated version of Internet Explorer. This demonstrates the point that how does wannacry can be so easily transmitted between various operating systems.
The worm may not have killed off the worm, but it has disabled the most effective defense: the Windows Security Center. This is the center for Microsoft’s personal firewall system, which has been one of the most effective lines of defense against how does wannacry infect your system. Once the worm has been disabled by the Windows Security Center, it may have simply redirected your web browser to a false website, leaving you vulnerable to further attacks. This attack has been occurring for a while, but it’s important to note that it only happened between April and May of this year. The most recent attack occurred in late August, which means that this worm could have been around for quite some time.
In short, a recent attack has caused Microsoft to issue an update to solve the “worm” issue that has been plaguing millions of Windows computers worldwide. However, with no additional prevention from the likes of phishing and malware, you’re at risk every single day when browsing the Internet. To protect yourself, make sure you keep up with the latest security updates, run a virus scan every day and get rid of any infections you find using the correct tools. If you want to know how does wannacry infect your PC, you need to make sure you have the proper protection.
