Flashback virus, also known as OSX.Flashback, Fakeflash, Flashback trojan, or Trojan BackDoor.Flashback. This fraudulent Trojan horse^[1] affects Mac users and their computer systems only. Furthermore, Flashback virus was discovered several years ago – in 2011 by an antivirus organization named Intego. The dangerous infection uses a tricky Adobe Flash Player installer with the name “Flashback” in order to infiltrate the victims' computer systems.^[2] It is very important to know that infections such as trojan ones are capable of secretly hiding on the infected machine and performing hazardous activity silently. Flashback trojan can also be very dangerous if kept on the system for a long time. A trojan infection can relate in many things such as the injection of other viruses, identity theft, program crashes or corruption, system sluggishness or unrepairable damage, high CPU and GPU usage, etc.

According to research, most people that were infected lived in The United States – about 56%, after that in Canada – 19.8%, United Kingdom – 12.8%, and in Australia – 6.1%. Furthermore, the trojan was modified into a more modern one called BackDoor.Flashback.39 and discovered in April 2017.^[3]

A report claimed that this dangerous virus infected numerous Mac machines by creating a botnet which contains 274 bots. This variant targeted Java vulnerabilities which were found on the Mac PC. Moreover, the trojan injected a malicious executable to be able to run a specific code from a remote server. Additionally, this version of the Flashback virus was able to infect only those users who visited the malware-laden website.^[4]
