This is called ransomware, a rather new form of malware that scrambles a sufferer’s documents, which requires a price to unscramble them.
Attacks like this have become increasingly common online. Last month, many computer systems were infected with ransomware dubbed WannaCry, causing disruptions for hospitals inside the United Kingdom.
Ars Technica’s Dan Goodin describes the carnage the software has prompted:
Initially, it took preserve in Ukraine and Russia, but it reportedly unfolded to Poland, Italy, Spain, France, India, and the US. WPP, the British advert employer, said on Twitter that a cyber attack had hit several IT structures. Its website remained unreachable, and this put-up turned into a going stay. Law firm DLA Piper posted a handwritten sign-up in one of its lobbies instructing personnel to take all laptops from docking stations and turn all computers off. AV issue Avast said it has detected 12,000 attacks up to now. Security business enterprise Group-IB said at least 80 corporations had been infected thus far. Reuters also reported that a laptop attack that hit Maersk, a transport business enterprise that handles one in seven of all containers globally, induced outages in any respect of its laptop structures internationally.
The new attack is sophisticated, using several upgrades over the strategies utilized by last month’s WannaCry malware. The software program steals credentials from victims’ computer systems and sends them to a server the attackers manage.

Yet, the attackers seem to have taken a lackluster approach to amassing ransom payments. That has caused some specialists to doubt that the attackers had been after money. Rather, they believe that the hackers looked to cause mayhem or thieve statistics from decided targets. They sincerely used ransomware to sow confusion about the character of the assault and who turned behind it.
The modern-day outbreak may also have been supposed for destruction, now not earnings.
The concept behind ransomware is simple: A criminal hacks into your laptop and scrambles your documents with unbreakable encryption, after which you pay for the encryption key needed to unscramble the documents. If you have crucial files on your PC, you might be willing to pay a lot to avoid dropping them.
One of the hardest things about developing ordinary ransomware is the need to collect ransom bills from sufferers again. Ransomware schemes have become much more effective since the invention of Bitcoin in 2009. Conventional fee networks like Visa and MasterCard make it hard to accept payments without revealing your identity. Bitcoin makes that much less complicated. So, over the past four years, we have seen a surge in ransomware schemes striking unsuspecting PC users.
However, an assault nonetheless wishes infrastructure to receive and verify bills, after which decryption keys can be distributed to victims — potentially lots of them. It needs to do this in a way that can’t be blocked or traced by using the government, which is why ransomware attackers often depend on the anonymous Tor network to communicate with victims.
Yet this week’s ransomware attack takes a lackluster method to this hassle. It instructs all sufferers to send bills to the identical Bitcoin cop, then ship facts about their price to the e-mail deal with wowsmith123456@posteo.Net.
But Poster blocked access to this account, making it impossible for victims to reach the attackers. Without a decryption key, victims have no incentive to pay the ransom.
It’s possible that this otherwise sophisticated attack’s perpetrators were naive about setting up its charge system. But it’s also viable that they disguised the software program as ransomware to camouflage the attack’s actual reason.
