The Mariposa botnet, discovered December 2008, [1] is a botnet mainly involved in cyberscamming and denial-of-service attacks. [2] [3] Before the botnet itself was dismantled on 23 December 2009, it consisted of up to 12 million unique IP addresses or up to 1 million individual zombie computers infected with the "Butterfly (mariposa in Spanish) Bot", making it one of the largest known botnets. [3] [4] [5]
The botnet was originally created by the DDP Team (Spanish: Días de Pesadilla Team, English: Nightmare Days Team), using a malware program called "Butterfly bot", which was also sold to various individuals and organisations. [2] [6] The goal of this malware program was to install itself on an uninfected PC, monitoring activity for passwords, bank credentials and credit cards. [2] After that the malware would attempt to self-propagate to other connectible systems using various supported methods, such as MSN, P2P and USB. [7]
After completing its initial infection routine the malware would contact a command-and-control server within the botnet. This command and control server could be used by the controllers of the botnet, in order to issue orders to the botnet itself. [8]
The operations executed by the botnet were diverse, in part because parts of the botnet could be rented by third party individuals and organizations. [9] Confirmed activities include denial-of-service attacks, e-mail spam, theft of personal information, and changing the search results a browser would display in order to show advertisements and pop-up ads. [8] [10]
Due to the size and nature of a botnet its total financial and social impact is difficult to calculate, but initial estimates calculated that the removal of the malware alone could cost "tens of millions of dollars". [8] [11] After the apprehension of the botnet's operators government officials also discovered a list containing personal details on 800,000 individuals, which could be used or sold for Identity theft purposes. [11]
The countries most infected by the botnet were India, Mexico, Brazil and South Korea. [12]
In May 2009 the Mariposa Working Group (MWG) was formed as an informal group, composed of Defence Intelligence, the Georgia Tech Information Security Center and Panda Security, along with additional unnamed security researchers and law enforcement agencies. The goal of this group was the analysis and extermination of the Mariposa botnet itself. [8]
On 23 December 2009 the Mariposa Working Group managed to take control of the Mariposa Botnet, after seizing control of the command-and-control servers used by the botnet. The operational owners of the botnet eventually succeeded in regaining control over the botnet, and in response launched a denial-of-service attack on Defence Intelligence. [8] The attack itself managed to knock out Internet connectivity for a large share of the ISP's customers, which included several Canadian universities and government agencies. [13]
On 3 February 2010, the Spanish national police arrested Florencio Carro Ruiz (alias: Netkairo) as the suspected leader of the DDP Team. Two additional arrests were made on 24 February 2010. Jonathan Pazos Rivera (alias: Jonyloleante) and Juan José Ríos Bellido (alias: Ostiator) were arrested on the suspicion of being members of DDP. [3] [8] [14] [15] [16]
On 18 July 2010, Matjaž Škorjanc (alias: Iserdo), the creator of the "Butterfly bot" malware, was arrested in Maribor by Slovenian police for the first time, [17] but released due to lack of evidence. He was arrested again in October 2011. [18] In December 2013 Škorjanc was convicted in Slovenia of "creating a malicious computer program for hacking information systems, assisting in wrongdoings and money laundering." [19] He was sentenced to 4 years and 10 months imprisonment and fined €3,000 ($3,000). [20] The court also ordered the seizure of Škorjanc's property acquired with the proceeds of crime. [21] After he appealed the verdict his fine was in February 2015 raised for additional 25,000 EUR. [22]
On 5 June, 2019, US law enforcement opened a new case in the operations of the Mariposa (Butterfly Bot, BFBOT) malware gang. FBI has moved forward with new charges and arrest warrants against four suspects including NiceHash's operator Matjaž Škorjanc. [23]

A botnet is a group of Internet-connected devices, each of which runs one or more bots. Botnets can be used to perform Distributed Denial-of-Service (DDoS) attacks, steal data, send spam, and allow the attacker to access the device and its connection. The owner can control the botnet using command and control (C&C) software. The word "botnet" is a portmanteau of the words "robot" and "network". The term is usually used with a negative or malicious connotation.
Shadowserver Foundation is a nonprofit security organization that gathers and analyzes data on malicious Internet activity, sends daily network reports to subscribers, and works with law enforcement organizations around the world in cybercrime investigations. Established in 2004 as a "volunteer watchdog group," it liaises with national governments, CSIRTs, network providers, academic institutions, financial institutions, Fortune 500 companies, and end users to improve Internet security, enhance product capability, advance research, and dismantle criminal infrastructure. Shadowserver provides its data at no cost to national CSIRTs and network owners.
Operation: Bot Roast is an operation by the FBI to track down bot herders, crackers, or virus coders who install malicious software on computers through the Internet without the owners' knowledge, which turns the computer into a zombie computer that then sends out spam to other computers from the compromised computer, making a botnet or network of bot infected computers. The operation was launched because the vast scale of botnet resources poses a threat to national security.

Zeus is a Trojan horse malware package that runs on versions of Microsoft Windows. It is often used to steal banking information by man-in-the-browser keystroke logging and form grabbing. Zeus is spread mainly through drive-by downloads and phishing schemes. First identified in July 2007 when it was used to steal information from the United States Department of Transportation, it became more widespread in March 2009. In June 2009 security company Prevx discovered that Zeus had compromised over 74,000 FTP accounts on websites of such companies as the Bank of America, NASA, Monster.com, ABC, Oracle, Play.com, Cisco, Amazon, and BusinessWeek. Similarly to Koobface, Zeus has also been used to trick victims of technical support scams into giving the scam artists money through pop-up messages that claim the user has a virus, when in reality they might have no viruses at all. The scammers may use programs such as Command prompt or Event viewer to make the user believe that their computer is infected.
Avalanche was a criminal syndicate involved in phishing attacks, online bank fraud, and ransomware. The name also refers to the network of owned, rented, and compromised systems used to carry out that activity. Avalanche only infected computers running the Microsoft Windows operating system.

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 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.
