Once the connection failed, the malware would send two more packets — the encrypter and the decrypter. This link to North Korea was cemented when the U.S. government charged one of the Lazarus Group’s most prominent hackers with two counts of conspiracy, a North Korean national named Park Jin Hyok, in September 2018 for his prominent role behind WannaCry. 4 What this investigation is about Investigation: WannaCry cyber attack and the NHS What this investigation is about 1 On Friday 12 May 2017 a global ransomware attack, known as WannaCry, affected more than 200,000 computers in at least 100 countries.

A CASE STUDY ON RANSOMWARE ATTACKS IN CYBER SECURITY By Lalit Yadav 17th October 2020 WannaCry ransomware ABSTRACTION : Ransomware is a malicious code that is used by cybercriminals to launch data kidnapping and lock screen attacks. In May 2017, a WannaCry ransomware crypto worm caused world-wide havoc when it targeted Microsoft Windows Operating Systems. WannaCry. In addition, 2017 saw the first reported ransomware attack on connected devices. The window to spread ransomware was given to WannaCry through an unpatched flaw in older Microsoft Windows versions. Relatedly, unknown persons attributed to the Lazarus Group were found to be attempting to launder a large amount of Bitcoin through a Swiss cryptocurrency exchange service called ShapeShift in October 2018. To do this, they split the Bitcoins into three “crypto wallets” to move into Monero, a cryptocurrency which is difficult to appropriate through judicial means. Days after the attack, security researchers found that registering the kill switch domain name prevented the encryption file from executing; subsequent versions of the malware attempted to bypass this with different killswitch domains, which were also quickly registered. Generally, ransomware attacks are isolated, only infecting devices that come into contact with the malware delivery system such as infected sites or links.

Do you remember the year 2017- when we endured not one, but two tremendous ransomware attacks, Wannacry and Petya? In the most prominent case, which was that of the NHS, in 2015 U.K. Secretary of State for Health Jeremy Hunt decided that the government would cease paying Microsoft for XP support. It propagated through EternalBlue, an exploit discovered by the United States National Security Agency (NSA) for older … Though this flaw, called EternalBlue, had been fixed with patches issued by Microsoft for free in March 2017, computers that were still running older Microsoft systems (Windows XP) were liable to pay $1000 per year to receive the same coverage. In the IT industry, ransomware and healthcare are two words often seen side by side. Infected systems in over 150 countries resulted in a measly $100,000 payout for the attackers — however, the losses in productivity and erased files are predicted to have reached into the billions. The malware that made businesses everywhere WannaCry is an important case study for everyone. Case Study : The WannaCry Ransomware Attack. The victim: a small taxi firm in East London with 12 networked PCs (six in a central office, with another six in small satellite offices located near the railway or London Underground stations). One day after the attack, Windows released a series of patches that repaired the SMB vulnerability; however, this did not help the devices already infected with the malware. The note presented two deadlines; a three-day timer that would double the price if victims didn’t pay up, and a seven-day hard deadline that, if missed, would instruct the program to erase all encrypted files. for the encryption, making it difficult to decrypt manually within the deadline.

View case study presentation - Copy.pptx from ECONOMICS 3577 at Jomo Kenyatta University of Agriculture and Technology, Nairobi. This made WannaCry dangerously pervasive, increasing its rate of infection exponentially. On May 7, 2019, Baltimore was hit with a ransomware attack. The majority of devices infected used an unpatched version of Windows 7, with a few instances of infection occurring in devices running Windows XP. that repaired the SMB vulnerability; however, this did not help the devices already infected with the malware.

While some arrests have been made, the Lazarus Group is still at large and has since launched other malware attacks. The name could be Intercomp (International Computer) as an example. Ironically, the ransomware did have a ‘demo’ option, which would randomly decrypt 10 files using a locally-stored RSA key in the decryptor program, in theory assuring victims that it was possible to get their files back. So far, around 13.5 Bitcoin ($37,000) has been laundered [Fox-Brewster, T., 2017 {1}]. This research represents the starting point of a process of reducing the attack surface in the case of ransomware attacks. Though the decryptor was included within the payload, users that paid the ransom weren’t guaranteed to get their files back. The next step was unusual — the dropper would attempt to connect to an unregistered domain made of a seemingly random string of numbers and letters, halting the attack if a successful connection was made, and continuing the attack if no connection was established. Most prominently, within 60 NHS organisations, the health record information of individual patients was made unavailable, operations had to be cancelled, and many Accident & Emergency centres (A&Es) were closed.
