Remember NotPetya ? The Ransomware that shut down thousands of businesses, organisations and banks in Ukraine as well as different parts of Europe in June this year. Now, Ukrainian government authorities are once again warning its citizens to brace themselves for next wave of "large-scale" NotPetya-like cyber attack. According to a press release published Thursday by the Secret Service of Ukraine (SBU), the next major cyber attack could take place between October 13 and 17 when Ukraine celebrates Defender of Ukraine Day (in Ukrainian: День захисника України, Den' zakhysnyka Ukrayiny). Authorities warn the cyber attack can once again be conducted through a malicious software update against state government institutions and private companies. The attackers of the NotPetya ransomware also used the same tactic—compromising the update mechanism for Ukrainian financial software provider called MeDoc and swapping in a dodgy update including the NotPetya computer v

However, the story is not as simple as it seems, which portrayed this man as a criminal. I recommend you to read complete article to understand the case better and then have an opinion accordingly.

Although the wave of WannaCry and Petya ransomware has now been slowed down, money-motivated hackers and cyber criminals have taken lessons from the global outbreaks to make their malware more powerful. Security researchers have now discovered at least one group of cyber criminals that are attempting to give its banking Trojan the self-spreading worm-like capabilities that made recent ransomware attacks go worldwide. The new version of credential stealing TrickBot banking Trojan, known as " 1000029 " ( v24 ), has been found using the Windows Server Message Block (SMB)—that allowed WannaCry and Petya to spread across the world quickly. TrickBot is a banking Trojan malware that has been targeting financial institutions across the world since last year. The Trojan generally spreads via email attachments impersonating invoices from a large unnamed "international financial institution," but actually leads victims to a fake login page used to steal credenti

Researchers from ESET security firm have found a very stealthy malicious code in the M.E.Doc software update which was injected by an unknown hacker or group of hackers in mid-April by exploiting a vulnerability.

The author of original Petya ransomware is back. After 6 months of silence, the author of the now infamous Petya ransomware appeared today on Twitter to help victims unlock their files encrypted by a new version of Petya, also known as NotPetya . "We're back having a look in NotPetya," tweeted Janus, a name Petya creator previously chose for himself from a villain in James Bond. "Maybe it's crackable with our privkey. Please upload the first 1MB of an infected device, that would help." This statement made by the Petya author suggests he may have held onto a master decryption key , which if it works for the new variant of Petya infected files, the victims would be able to decrypt their files locked in the recent cyber outcry. Janus sold Petya as a Ransomware-as-a-Service (RaaS) to other hackers in March 2016, and like any regular ransomware, original Petya was designed to lock victim's computer, then return them when a ransom is paid.

What if I say the Tuesday's devastating global malware outbreak was not due to any ransomware infection? Yes, the Petya ransomware attacks that began infecting computers in several countries, including Russia, Ukraine, France, India and the United States on Tuesday and demands $300 ransom was not designed with the intention of restoring the computers at all. According to a new analysis, the virus was designed to look like ransomware but was wiper malware that wipes computers outright, destroying all records from the targeted systems. Comae Technologies Founder Matt Suiche, who closely looked the operation of the malware, said after analyzing the virus, known as Petya, his team found that it was a " Wiper malware ," not ransomware. Security experts even believe the real attack has been disguised to divert world's attention from a state-sponsored attack on Ukraine to a malware outbreak. "We believe the ransomware was, in fact, a lure to control the
