Hackers using trending events to manipulate end-users into falling for cyberattacks is nothing new. So when Windows rolled-out its Vanadium 1909 feature pack update, it was only a matter of time before this was leveraged by cybercriminals to launch phishing attacks.
Currently, a spam campaign is out seeking victims. The phishing emails come with subject lines like “Install Latest Microsoft Windows Update now!” or “Critical Microsoft Windows Update!” In case you didn’t already know, Microsoft will never push updates through emails.
These phishing emails will also ask you to install the latest Windows update by clicking on a fake JPEG attachment that is not actually an image file, but an executable developed by hackers to install Cyborg ransomware in your machines.
What can Cyborg do to your machines?
- This .NET-compiled ransomware encrypts all the files in an infected machine once activated.
- It appends filenames with invalid “.777” file extensions.
- It then leaves a text file open including a ransom note.
- Finally, it leaves a copy of itself named “bot.exe” in the infected drive.
It’s also reported that the ransomware builder is an executable file hosted on Github. Once someone gets hold of the Cyborg Builder Ransomware V 1.0.exe, it can be used to create multiple malware variants, and new phishing campaigns can be launched all over again. Moreover, this ransomware can be carefully crafted to avoid identification. With a huge number of email-based attacks happening in the cyberspace and the accessibility of a ransomware builder on a development platform like Github, organizations need to up their cybersecurity strategies to address this critical issue.
