BlackCat: Dangerous ransomware attacks companies

Dangerous ransomware preys on companies

BlackCat is the first ransomware written in the Rust programming language. The developers try to trick security programs because some do not check for the rather unusual programming language. The high casualty figures suggest that the endeavor is quite successful. The ransomware virus tries to steal access data before encrypting the data it finds, after which it takes all interesting files digitally hostage. The malware is primarily aimed at companies, as they are often willing to pay higher ransoms – but it also infects private PCs. You should therefore be particularly careful, both professionally and privately. And remember: paying the ransom is no guarantee that the criminals will actually decrypt the data again!

How to protect yourself from ransomware

Ransomware is most commonly spread via emails with malicious attachments. Such emails can even come from real contacts if the ransomware infected their PCs and stole their credentials. Therefore, note the following tips:

• Always be skeptical when it comes to mail attachments that you did not expect or request. If necessary, ask by phone.
• Only allow Office’s macro function if you are really sure that the macros are harmless.
• Protect the PC with an antivirus program.
• Use two-factor authentication for your email and bank accounts.
• Always keep your operating system and installed programs up to date.
