macOS users are confident that no malicious programs exist for this operating system. But they are wrong.
The first ones
- 1982 – the first Trojan for Mac appeared
- 2006 – the first Trojan for macOS (Mac.Leap) was discovered
- 2009 – the first Mac botnet (the Trojan Mac.Iservice) was exposed
- June 2009 – Doctor Web released its anti-virus for macOS
Malware programs for Macs do exist, but compared with Windows, their number is relatively small.

So malware for Macs does exist. But how does it sneak onto computers?
So it turns out that no security measure can protect a Mac from user carelessness. No matter how hard a manufacturer tries to make an operating system secure, users download programs containing malicious code and use administrator permissions to install them!
If a Mac is operated by an inexperienced user, the risk of infection increases dramatically.
Means of transport #2: Vulnerabilities
To spread malware for macOS, intruders also exploit vulnerabilities. Vulnerabilities are program code flaws that enable malware to infiltrate a Mac without user knowledge or consent.
Just like any other piece of software, macOS also has vulnerabilities.
It was namely vulnerabilities that played a major role in the first-ever outbreak of the malicious program BackDoor.Flashback.39.for macOS.
- In February 2012 criminals started using Java vulnerabilities to spread BackDoor.Flashback.39, and after March 16 they began using yet another exploit.
- March 2012 – Oracle released an update for the Java Virtual Machine, closing the vulnerabilities exploited by BackDoor.Flashback.39.
- As late as April 2012, Apple released an update for its own Java implementation to close the vulnerabilities exploited by BackDoor.Flashback.39.
Outbreak! 650,000 Macs
were infected with BackDoor.Flashback worldwide
More than 4 million websites
involved in spreading BackDoor.Flashback
How can macOS users protect their machines from infection?
Security tips from Doctor Web:
- Only download software from the developer’s site or from the App Store.
- To maintain real-time security, use an anti-virus that incorporates a resident monitor (e.g., in Dr.Web Anti-virus for macOS, this component is called SpIDer Guard).
- Use the HTTP monitor Dr.Web SpIDer Gate to protect your Mac from malware on websites. It will scan all the HTTP traffic and control access to Internet sites according to various thematic categories such as drugs, terrorism, violence, etc.
