WannaCry Is Dead (For Now): How to Protect Yourself Against the Next Ransomware Attack

Earlier this calendar month, a strain of ransomware infected more 300,000 Windows PCs around the world. The awesomely named WannaCry strain demanded that infected businesses and individuals pay $300 in order to unlock each machine—as well every bit the information stored on their devices. Some people paid the ransom, while others were lucky plenty to expect it out and exist rescued past a hero who accidentally stopped the attack past registering the unregistered domain on which the ransomware lived.

Now that the assail has been thwarted, it appears that new WannaCry variants are emerging, and a massive, unrelated ransomware attack striking Eastern Europe. As ransomware attacks become trickier and more hard to terminate, your company is more likely than e'er to be at take chances. As a consequence, we've compiled this list of mail-mortem steps on what happened, how yous can protect your concern and yourself, and what yous should do if you fall victim to an attack.

1. Be Defensive

You're going to need to be smarter most which emails you open up, which links you click, and which files you lot download. Phishing attacks are common and they're easy to fall victim to. Unfortunately, WannaCry wasn't your typical phishing assail. Instead, this assault manipulated a Windows vulnerability, one that had already been patched by Microsoft earlier this year.

And then, how did it get through? Y'all know those annoying pop-up notifications that software manufacturers send to your computer? They're not just alerting you lot to new features; they're calculation patches to your software that will help to protect confronting attacks like WannaCry. The same goes for your endpoint protection software. If your vendor asks you to update, and then update. In this example, it appears the attackers were able to penetrate systems that had not recently been updated and, as a consequence, hospitals were bedridden and lives were put in jeopardy (more on this later on).

"The global fallout of this attack could have hands been prevented past deploying the security update in one case it was made available by Microsoft," said Liviu Arsene, Senior E-Threat Analyst at Bitdefender. "The lesson to exist learned from this feel is to always utilise security patches and updates when they get bachelor, not simply for operating systems merely for applications too. Of class, a security solution might prevent the payload—in this example, ransomware—from infecting victims. But more avant-garde and sophisticated threats could potentially leverage the operating arrangement vulnerability to gain persistency and bypass traditional security mechanisms undetected."

2. Dorsum that Cache Up

The worst thing about an attack of this variety is that it gains access to your information. Nonetheless, the responsible among us don't need to worry about this very much because they have been using disaster recovery (DR) software to ensure that their data is live and well in the deject. If you air current up getting hit with a ransomware attack, and so having admission to your full trove of data in the cloud means y'all can but factory-reset your machine, pull in your backed up data, and start working again.

iii. Don't Pay, Silly

As much equally y'all'd like to retrieve your unfinished screenplay, paying earnest takers seldom works. Instead, contact the FBI and allow them know you've become the victim of a cyberattack. If yous desperately need your information and you don't accept a backup stored elsewhere, so only sit tight and expect. Too, if you lot don't need your data or if you take backed it upwardly, then just reset your car and start from scratch.

Whatever you do, don't pay. Here's why: There's a good possibility the hacker won't actually release your data. Now you're out $300 and you lot're still out of luck. Also, paying could actually expose you to additional risk because you've shown a willingness to requite into the hackers' demands. And then, in the very best-example scenario, y'all've paid, gotten your data back, and given a criminal incentive to try to assault you again in the future.

"No i is ever encouraged to requite in to ransomware demands," said Arsene. "In fact, if no backups are available from which to restore lost data, companies or individuals should treat the incident as hardware failure and move on. Paying would merely fuel cybercriminals with the financial resources to go along developing new threats. And in that location's no actual guarantee that you'll actually receive the decryption key. You are actually dealing with criminals here."

iv. What You Should Do

Equally I previously mentioned, backing upward your data and running a factory-reset on your hardware, will let yous walk away from a ransomware attack without having experienced much existent damage. Here's a step-by-footstep process for what to do when that ransom note hits your screen: 1) Unplug your computer and unplug your figurer from its network. 2) Fully wipe your device and restore it from a backup. 3) Install all security patches and updates and add a security solution like Bitdefender to your software mix. 4) Contact the FBI.

5. Businesses Must Get Serious

"There are security layers that companies can deploy to protect infrastructures from cipher-day vulnerabilities in both operating systems and applications," said Arsene. Arsene recommends organizations running virtual infrastructures deploy a hypervisor-based memory introspection technology that's capable of securing virtual workloads.

"This new security layer that sits below the operating arrangement tin detect cipher-mean solar day vulnerabilities, like the SMB v1 vulnerability leveraged by WannaCry, and prevent attackers from ever exploiting information technology, even if the arrangement is unpatched or the vulnerability is completely unknown," Arsene explained. "This complementary security layer, coupled with traditional in-guest security solutions and constant software patching, increases the toll of assail for cybercriminals while giving organizations more visibility into advanced attacks."
