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.
