Beware of these documents on WhatsApp! One mistake could get your phone hacked.

Opening unknown documents on WhatsApp can prove costly. Hackers can inject malware into your phone via fake files. Here is how you can avoid such documents and keep your phone secure.

Today, WhatsApp is not just a medium for chatting; it is widely used to share documents, photos, videos, and other important files. Cybercriminals are now exploiting this trust. Cybersecurity firm Quick Heal Technologies has issued a warning regarding a new malware campaign spreading via WhatsApp. In this campaign, hackers send malicious files disguised as ordinary-looking documents.

How is the malware spreading via WhatsApp?

According to media reports, attackers first compromise a WhatsApp account. They then send suspicious files to contacts listed in that account. The biggest issue is that the message does not come from an unknown number but from the account of an acquaintance, colleague, or business contact. Consequently, the user is more likely to trust the file.

Hackers try to make these files look like standard business documents. This is why simply recognizing the sender is no longer enough. If an acquaintance suddenly sends an unexpected document, it is crucial to verify it before opening it.

Who is being targeted?

According to Quick Heal, this campaign specifically targets finance teams, senior executives, chartered accountants, and business users. Since these users may have financial documents and sensitive business information on their phones or computers, compromising their devices offers greater value to cybercriminals. The report also notes that attackers are constantly changing file formats and techniques to evade security systems.

Keep these points in mind to stay safe:

If you receive a suspicious document on WhatsApp—even from an acquaintance—do not download or open it immediately. First, contact the person via a phone call or another channel to verify if they actually sent the file. Also, avoid sharing unknown or suspicious files.

Additionally, always keep your phone and computer operating systems and security software updated. It is best to ignore any file that arrives with an unusual name, strange format, or suspicious context. Cybersecurity experts advise that one needs to be more vigilant than ever regarding files received on WhatsApp.
