How to Protect Your Business From Petya Ransomware - iCorps

You may have seen the news that a massive ransomware attack, spread via email, infected systems in Russia and Ukraine early Tuesday morning and quickly spread to the west, becoming a global issue in only a matter of hours. This attack, caused by Petya Ransomware, is anticipated to spread to the United States, leaving a massive impact not unlike the recent WannaCry Ransomware attack. Ransomware is malicious software that encrypts victim’s data and demands a ransom to unlock it. While the specifics of the attack are not yet known, there have been major IT disruptions for various organizations across several industries. We’d like to explain how this Petya Ransomware attack spread and what countermeasures are available to protect your organization from this threat and others like it.

How did this happen?
This particular ransomware variant spreads via email attachments such as Word documents and PDF files. Unlike other ransomware attacks, it does not encrypt your files; instead, the virus targets the hard drive, leaving your systems inaccessible. Petya attacks as soon as a computer boots up, so users do not have any time to react to the virus. Like WannaCry, this ransomware takes advantage of a vulnerability, or flaw, in Microsoft operating systems including both desktop and server operating systems. While Microsoft released a patch to fix this flaw on March 14, 2017, some systems still remained unpatched for various reasons. This attack is able to infect systems that did not have the March 14th patch applied.
