Ransomware attack

Ransomware part II

Ransomware is a type of malicious software that blocks access to your system or personal files and then demands a payment (a ransom) to restore access. Although it feels like a modern threat, ransomware has been around since the late 1980s, when victims were asked to mail in their payments. Today, cybercriminals typically demand payment through cryptocurrencies or prepaid cards, making the money harder to trace.

One of the most common ways ransomware spreads is through malicious spam (malspam) — unwanted emails that deliver malware. These emails often contain infected attachments, such as PDFs or Word documents, or links that lead to dangerous websites. The messages are designed to look legitimate, sometimes impersonating companies, services you use, or even people you know.

Malspam relies heavily on social engineering, using psychological tricks to make you click before you think. Attackers craft convincing subject lines, company logos, and sender names so their messages appear genuine. Once you open the attachment or click the link, the ransomware can install itself silently in the background and begin encrypting your files.

Another long-standing infection method is malicious advertising, or “malvertising.” As the name suggests, this involves using online ads to deliver malware. These ads can show up even on reputable websites. In some cases, you do not even need to click on the ad; just loading the page is enough to send you to a criminal server. There, attackers automatically analyze your system, identify your location and software, and then deliver the most suitable malware — often ransomware.

How can you protect yourself from ransomware?

  • Keep your operating system updated to patch security vulnerabilities.
  • Install a reputable antivirus solution and keep it updated.
  • Do not open emails, attachments, or links from unknown or suspicious senders.
  • Avoid browsing unfamiliar or risky websites and be cautious with pop-ups and ads.
  • Maintain regular, up-to-date backups of your important files on an external drive or secure cloud service, so you can recover your data without paying criminals.
