WhatsApp malware campaign has raised concerns among users who regularly share documents, photos and other files on the messaging platform.
Cybersecurity company Quick Heal Technologies has warned that attackers are sending malicious files by disguising them as normal documents.
The campaign can be more dangerous because hackers may first take control of a WhatsApp account and then use it to send suspicious files to people in the account’s contact list.
WhatsApp Malware Is Spreading Through Fake Documents
According to media reports, attackers are taking control of WhatsApp accounts and sending suspicious files to contacts.
The message may appear to come from a known person such as an acquaintance, coworker or business contact.
Hackers are reportedly disguising dangerous files as regular business documents. Because of this, users should not trust a file only because it appears to have been sent by someone they know.
If a contact suddenly sends an unexpected document, users should first confirm with that person whether they actually sent the file before opening it.
Who Is Being Targeted by This Campaign
Quick Heal says the campaign is specifically targeting finance teams, senior executives, chartered accountants and business users.
These users may have financial documents and other sensitive business information stored on their phones or computers, which can make such devices valuable targets for cybercriminals.
The report also states that attackers are continuously changing file formats and techniques to bypass security systems.
How to Stay Safe From Suspicious WhatsApp Files
Users should avoid immediately downloading or opening an unexpected document received on WhatsApp, even when it appears to come from an acquaintance. It is better to contact the sender directly and confirm whether the file was actually sent by them.
Users should also avoid forwarding unknown or suspicious files to other people. An unusual file name, strange format or unexpected message context should be treated as a warning sign.
Keep Your Phone and Computer Updated
Keeping the operating system and security software on phones and computers updated can provide additional protection against malware.
Cybersecurity experts advise users to be especially careful with documents received through WhatsApp. Verifying an unexpected file before opening it can help reduce the risk of falling victim to malicious files.
