Companies weigh cyberattack cost, with Ukraine hit hard

Companies weigh cyberattack cost, with Ukraine hit hard

This is one of the reasons why it being called "NotPetya", "Petrwrap", "exPetr" or "Nyetya". Both Petya and WannaCry exploit the EternalBlue vulnerability in Windows XP and other Microsoft Windows systems to carry out the attack.

Having said that, its behavior is unlike the WannaCryptor as there is no external scanning component.

The WannaCry outbreak prompted many network administrators to update their security patches.

Rosneft, Bashneft, Mars, Nivea and Mondelez International (producer of Alpen Gold chocolate) are among the companies that were attacked by the Petya virus in Russia, Group-IB, the company which deals with prevention and investigation of cybercrime, reported, according to TASS.

JNPT chairman Anil Diggikar said the port has been trying to clear containers manually and is operating at about a third of its capacity.

The first attacks were reported from Russian Federation and Ukraine which, according to Kaspersky Lab, were most affected by the thousands of attacks.

Rosneft is now suing private firm Sistema for 170 billions rubles (2.55 billion euros, $2.88 billion) over the state giant's acquisition of oil company Bashneft.

NotPetya ransomware attack, New Zealand view
One of the terminals at the JNPT port has been impacted by the latest malware attack, the government confirmed today. A number of Irish computer users have reported demands for up to €300 in Bitcoin to unlock their infected PCs.

Marco Cova, a researcher at the United States cybersecurity company Lastline, commented for The Times by saying that Petya looked "very similar in its dynamics and techniques" to Wannacry and appeared to rely on the same piece of software, called EternalBlue, to help it spreading. It uses the EternalBlue exploit, but exactly how it spreads hasn't been confirmed. The exploit attacks vulnerable Windows Server Message Block (SMB) service, which is used to share files and printers across local networks.

While the infection has spread worldwide already, the open-source cybersecurity community sprang into action immediately and discovered the digital 'vaccine'. A bitcoin wallet used to collect ransoms showed only about $10,000. Thus, people shouldn't pay for the ransom as they will not be able to receive the decryption key.

Ukraine, the epicenter of the cyber strike, has repeatedly accused Russian Federation of orchestrating attacks on its computer systems and critical power infrastructure since its powerful neighbor annexed the Black Sea peninsula of Crimea in 2014.

We can not emphasise enough the importance of keeping all devices and systems patched and up-to-date.

In a day's span, GoldenEye affected about 2,000 users, according to Kaspersky Lab analysts.

Further to that, customers may choose to restrict the use of PsExec and other dual-use administrative tools on their network. Once it reboots, it starts to encrypt the MFT table in NTFS partitions, overwriting the MBR with a customized loader with a ransom note. Unlike Wannacry, this technique would work because the attackers are asking the victims to send their wallet numbers by e-mail to "wowsmith123456@posteo.net", thus confirming the transactions. But Cisco Talos says one way the ransomware got into computer systems was through software in Ukraine, a country that was hit especially hard by the attacks.

What does the Petya Ransomware do?The Petya ransomware encrypts files and documents on an infected machine, like most ransomware and it also replaces the original Master Boot Record (MBR) of an infected machine so that this computer can no longer boot into Windows.
