Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program. A keystroke recorder or keylogger can be either software or hardware.

Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet is an inherently insecure channel for information exchange, with high risk of intrusion or fraud, such as phishing, online viruses, trojans, ransomware and worms.
Crimeware is a class of malware designed specifically to automate cybercrime.
Mobile malware is malicious software that targets mobile phones or wireless-enabled Personal digital assistants (PDA), by causing the collapse of the system and loss or leakage of confidential information. As wireless phones and PDA networks have become more and more common and have grown in complexity, it has become increasingly difficult to ensure their safety and security against electronic attacks in the form of viruses or other malware.
A transaction authentication number (TAN) is used by some online banking services as a form of single use one-time passwords (OTPs) to authorize financial transactions. TANs are a second layer of security above and beyond the traditional single-password authentication.
Credit card fraud is an inclusive term for fraud committed using a payment card, such as a credit card or debit card. The purpose may be to obtain goods or services or to make payment to another account, which is controlled by a criminal. The Payment Card Industry Data Security Standard is the data security standard created to help financial institutions process card payments securely and reduce card fraud.
Man-in-the-browser, a form of Internet threat related to man-in-the-middle (MITM), is a proxy Trojan horse that infects a web browser by taking advantage of vulnerabilities in browser security to modify web pages, modify transaction content or insert additional transactions, all in a covert fashion invisible to both the user and host web application. A MitB attack will be successful irrespective of whether security mechanisms such as SSL/PKI and/or two- or three-factor authentication solutions are in place. A MitB attack may be countered by using out-of-band transaction verification, although SMS verification can be defeated by man-in-the-mobile (MitMo) malware infection on the mobile phone. Trojans may be detected and removed by antivirus software;, but a 2011 report concluded that additional measures on top of antivirus software were needed.
Form grabbing is a form of malware that works by retrieving authorization and log-in credentials from a web data form before it is passed over the Internet to a secure server. This allows the malware to avoid HTTPS encryption. This method is more effective than keylogger software because it will acquire the user’s credentials even if they are input using virtual keyboard, auto-fill, or copy and paste. It can then sort the information based on its variable names, such as email, account name, and password. Additionally, the form grabber will log the URL and title of the website the data was gathered from.
Multi-factor authentication is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence to an authentication mechanism. MFA protects personal data—which may include personal identification or financial assets—from being accessed by an unauthorized third party that may have been able to discover, for example, a single password.
Clampi is a strain of computer malware which infects Windows computers. More specifically, as a man-in-the-browser banking trojan designed to transmit financial and personal information from a compromised computer to a third party for potential financial gain as well as report on computer configuration, communicate with a central server, and act as downloader for other malware. Clampi was first observed in 2007 affecting computers running the Microsoft Windows operating system.
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.
Experi-Metal, Inc., v. Comerica Bank is a decision by the United States District Court for the Eastern District of Michigan in a case of a phishing attack that resulted in unauthorized wire transfers of US$1.9 million through Experi-Metal's online banking accounts. The court held Comerica liable for losses of US$560,000 that could not be recovered from the phishing attack, on the ground that the bank had not acted in good faith when it failed to recognize the transfers as fraudulent.
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.
Operation Tovar is an international collaborative operation carried out by law enforcement agencies from multiple countries against the Gameover ZeuS botnet, which is believed by the investigators to have been used in bank fraud and the distribution of the CryptoLocker ransomware.
GameOver ZeuS (GOZ), also known as peer-to-peer (P2P) ZeuS, ZeuS3, and GoZeus, is a Trojan horse developed by Russian cybercriminal Evgeniy Bogachev. Created in 2011 as a successor to Jabber Zeus, another project of Bogachev's, the malware is notorious for its usage in bank fraud resulting in damages of approximately $100 million and being the main vehicle through which the CryptoLocker ransomware attack was conducted, resulting in millions of dollars of losses. At the peak of its activity in 2012 and 2013, between 500,000 and 1 million computers were infected with GameOver ZeuS.
Tiny Banker Trojan, also called Tinba, is a malware program that targets financial institution websites. It is a modified form of an older form of viruses known as Banker Trojans, yet it is much smaller in size and more powerful. It works by establishing man-in-the-browser attacks and network sniffing. Since its discovery, it has been found to have infected more than two dozen major banking institutions in the United States, including TD Bank, Chase, HSBC, Wells Fargo, PNC, and Bank of America. It is designed to steal users' sensitive data, such as account login information and banking codes.
Dridex, also known as Bugat and Cridex, is a form of malware that specializes in stealing bank credentials via a system that utilizes macros from Microsoft Word.
ZeuS Panda, Panda Banker, or Panda is a variant of the original Zeus under the banking Trojan category. Its discovery was in 2016 in Brazil around the time of the Olympic Games. The majority of the code is derived from the original Zeus trojan, and maintains the coding to carry out man-in-the-browser, keystroke logging, and form grabbing attacks. ZeuS Panda launches attack campaigns with a variety of exploit kits and loaders by way of drive-by downloads and phishing emails, and also hooking internet search results to infected pages. Stealth capabilities make not only detecting but analyzing the malware difficult.
Jabber Zeus was a cybercriminal syndicate and associated Trojan horse created and run by hackers and money launderers based in Russia, the United Kingdom, and Ukraine. It was the second main iteration of the Zeus malware and racketeering enterprise, succeeding Zeus and preceding Gameover Zeus.

In its latest versions, SpyEye has been modified with new code designed to evade advanced systems banks have put in place to try and block fraudulent transactions, said Mickey Boodai, Trusteer's CEO. Banks are now analyzing how a person uses their site, looking at parameters such as how many pages a person looks at on the site, the amount of time a person spends on a page and the time it takes a person to execute a transaction. Other indicators include IP address, such as if a person who normally logs in from the Miami area suddenly logs in from St. Petersburg, Russia. SpyEye works fast, and can automatically and quickly initiate a transaction much faster than an average person manually on the website. That's a key trigger for banks to block a transaction. So SpyEye's authors are now trying to mimic -- albeit in an automated way -- how a real person would navigate a website.

SpyEye is notable for its ability to inject new fields into a Web page, a technique called HTML injection, which can ask banking customers for sensitive information they normally would not be asked. The requested data can include logins and passwords or a debit card number. It can also use HTML injection to hide fraudulent transfers of money out of an account by displaying an inaccurate bank balance. Trusteer noticed that SpyEye also hides fraudulent transactions even after a person has logged out and logged back into their account. The latest feature is designed with the same goal of keeping users unaware of fraud. The next time users log into their bank accounts, SpyEye will check its records to see what fraudulent transactions were made with the account, then simply delete them from the Web page, said Amit Klein, Trusteer's CEO. The account balance is also altered.
