cypress infostealerSecurity researchers reported a new information stealer trojan that can steal your login credentials, credit card and bank account details, and other types of highly sensitive personal information. The information stealer is known as Cypress and Spyware.Cypress, but it has various detection names (see our table below for details).

The Cypress trojan has a high detection rate – 44 out of 70 security engines detect it, according to VirusTotal.

Shortly said, the Cypress trojan is a dangerous malware sample that puts your online security at risk after it obtains access to your operating system. Unfortunately, trojans can sneak into your system unnoticed, and stay there for long periods of time. Once started on a target system, the Trojan can trigger various malicious operations that threaten your sensitive (personal and financial) information. It may also be the cause for further malware intrusions, especially if it has a backdoor functionality.

Malware programs such as the Cypress information stealer are developed to support various hacking activities. Trojans may sometimes install additional malware, establish a remote connection to hackers’ servers, obtain data, and apply other changes that disrupt system security.

Other examples of information stealers are the MassLogger malware distributed in phishing emails and Raccoon infostealer malware.

If you believe that your system is hacked by the Cypress trojan, you should definitely perform a thorough check of your operating system. For help in the removal process, you can use the removal instructions at the end of this article.

What Is Cypress Infostealer Trojan?

The Cypress infostealer can invade Windows operating systems in a stealthy manner. This type of malware can seriously damage an infected computer.

The spyware trojan has been released in the wild, and as a result, it is lurking in the web trying to infect as many Windows machines as possible. It may present itself as a fake Flash Player update, as a supposedly useful free app, or as an urgent email.

Its access to a computer enables it to establish a few malicious files that may compromise both the system and the network. Since it aims to remain undetected for as long as possible, you may spot it after it has successfully corrupted your operating system. One way to catch this threat is to notice that some of the installed programs do not run correctly.

The Cypress spyware may also help in the installation of additional malware on the system. Since the added malware can be of any kind, your device may be hit by ransomware, spyware, another Trojan, adware, etc.

Its main presence on the system is associated with data theft. Hackers can steal sensitive login credentials for various accounts, perform fraudulent transactions, get access to your email accounts to send spam, and many more. Shortly said, beware of the Cypress trojan. We recommend using an advanced security tool for its complete removal. Otherwise, some elements installed by the infostealer may remain on your computer, leaving it vulnerable for future infections.

In terms of distribution, these are the most common methods used by cybercriminals to spread trojans such as Cypress infostealer:

  • Exploit kits;
  • Phishing emails;
  • Bundled freeware installers;
  • Fake updates and infected pages.
