While plenty of malware target Windows and Android operating systems, Apple products also get some unwanted attention from cybercriminals. In February, Fancy Bear, the Russian hacking group accused of leaking information from the US Democratic National Committee, have created advanced malware for Macs and iOS backups. Here’s how the exploit works.
According to antivirus provider Bitdefender, the new malware — named Xagent — is a Mac OS backdoor that is usually delivered via spear phishing emails.
To deploy the malware, hackers attach a Trojan software downloader in the email. If users interact with it, the program immediately creates a backdoor and connects to the cybercriminal’s network.
The malware then avoids detection by checking for antivirus software; and if it determines that cybersecurity solutions are offline or unpatched, it will begin to send system information, locally-saved passwords, iPhone backups, and desktop screenshots back to hacker headquarters.
Although security updates for the new malware are still unavailable, there are some things you can do to minimize the possibility of infection.
Approach emails with caution
Since hackers use phishing scams to distribute the Xagent malware, train your staff to be critical of email links or attachments, even if from the CEO or a close friend. And under no circumstances should you interact with any email from an unknown sender.
Keep your OS up-to-date
Always remember to install the latest operating system and application updates to make sure that Mac vulnerabilities are covered immediately.
Don’t save passwords
While it may be easier to save your passwords on your local browser, it gives hackers easy access to your accounts. If you can’t remember all your passwords, consider password management software. And while we’re on the subject, make sure you set unique passwords with a good combination of letters, numbers, and symbols.
To add another layer of protection, encrypt your iOS backups. This ensures that unauthorized users won’t be able to read the contents of your iOS data even if they do manage to gain access to your computer.
Cybersecurity is a universal issue, even for Mac users. But adopting these basic security habits will keep any hacker, whether from Russia or the US, at bay. Fortify your defenses by giving us a call today.
