History

Emsisoft is an anti-malware and cybersecurity software and consulting company founded in Austria in 2003 by Christian Mairoll. [5] [6] The company makes anti-malware software and decryption tools used by companies and individuals to help them recover computer files encrypted in ransomware attacks. [7] [8] It also tracks and generates studies on ransomware attacks. [9] [10]

Mairoll, who is CEO, relocated to rural New Zealand in 2014, [11] moving Emsisoft’s headquarters to the country, while its employees across Europe, Asia and the United States remained remote. [12] [5]

In 2019, Emsisoft donated decryption tools to Europol's No More Ransom project. [13] The company’s decryption tools were also used to help resolve the Kaseya VSA ransomware attack, [14] DarkSide and BlackMatter ransomware attacks against dozens of companies across the U.S., Europe and Britain in 2021. [15] [16]

Ireland’s National Cyber Security Centre used Emsisoft’s decryption tools in May 2021 to help the country's health service department recover from a ransomware attack. [17]

In early 2021, Emsisoft suffered a system data breach due to a configuration error, leading to the release of a database containing log records, including email addresses, generated by Emsisoft, that were accessed by at least one unauthorized individual. [18] After detecting the attack, Emsisoft implemented security mechanisms, including disconnecting the compromised system and investigated the incident using forensic analysis. Customers were notified and Emsisoft issued a public apology for the incident. [19]

Technology

Emsisoft's anti-malware technology is called Emsisoft Anti-Malware and has three versions: Anti-Malware Home, Business Security and Enterprise Security. [7] [8] [20] The company also makes an extension for the web browsers Google Chrome, Firefox and Microsoft Edge that enables blocking access to malicious and phishing websites. [20]

Ransomware is a type of cryptovirological malware that permanently blocks access to the victim's personal data unless a "ransom" is paid. While some simple ransomware may lock the system without damaging any files, more advanced malware uses a technique called cryptoviral extortion. It encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem, and difficult-to-trace digital currencies such as paysafecard or Bitcoin and other cryptocurrencies are used for the ransoms, making tracing and prosecuting the perpetrators difficult.

A supply chain attack is a cyber-attack that seeks to damage an organization by targeting less secure elements in the supply chain. A supply chain attack can occur in any industry, from the financial sector, oil industry, to a government sector. A supply chain attack can happen in software or hardware. Cybercriminals typically tamper with the manufacturing or distribution of a product by installing malware or hardware-based spying components. Symantec's 2019 Internet Security Threat Report states that supply chain attacks increased by 78 percent in 2018.

Cyberweapons are commonly defined as malware agents employed for military, paramilitary, or intelligence objectives as part of a cyberattack. This includes computer viruses, trojans, spyware, and worms that can introduce malicious code into existing software, causing a computer to perform actions or processes unintended by its operator.

The CryptoLocker ransomware attack was a cyberattack using the CryptoLocker ransomware that occurred from 5 September 2013 to late May 2014. The attack utilized a trojan that targeted computers running on Microsoft Windows, and was believed to have first been posted to the Internet on 5 September 2013. It propagated via infected email attachments, and via an existing Gameover ZeuS botnet. When activated, the malware encrypted certain types of files stored on local and mounted network drives using RSA public-key cryptography, with the private key stored only on the malware's control servers. The malware then displayed a message which offered to decrypt the data if a payment was made by a stated deadline, and it threatened to delete the private key if the deadline passes. If the deadline was not met, the malware offered to decrypt data via an online service provided by the malware's operators, for a significantly higher price in bitcoin. There was no guarantee that payment would release the encrypted content.

<span class="mw-page-title-main">WannaCry ransomware attack</span> 2017 worldwide ransomware cyberattack

The WannaCry ransomware attack was a worldwide cyberattack in May 2017 by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. It was propagated by using EternalBlue, an exploit developed by the United States National Security Agency (NSA) for Windows systems. EternalBlue was stolen and leaked by a group called The Shadow Brokers a month prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these, or were using older Windows systems that were past their end of life. These patches were imperative to cyber security, but many organizations did not apply them, citing a need for 24/7 operation, the risk of formerly working applications breaking because of the changes, lack of personnel or time to install them, or other reasons.

EternalBlue is a computer exploit software developed by the U.S. National Security Agency (NSA). It is based on a vulnerability in Microsoft Windows that allowed users to gain access to any number of computers connected to a network. The NSA knew about this vulnerability but did not disclose it to Microsoft for several years, since they planned to use it as a defense mechanism against cyber attacks. In 2017, the NSA discovered that the software was stolen by a group of hackers known as the Shadow Brokers. Microsoft was informed of this and released security updates in March 2017 patching the vulnerability. While this was happening, the hacker group attempted to auction off the software, but did not succeed in finding a buyer. EternalBlue was then publicly released on April 14, 2017.
