Dubai alert malware as pdf attachment on WhatsApp and emails

The TRA also called upon online users, including people and institutions, "to exercise maximum caution while dealing with PDF files mailed from anonymous sources," citing official figures from McAfee, a global computer security software company.

The UAE Telecommunications Regulations Authority (TRA) alerted citizens of PDF malware files sent anonymously to mails or WhatsApp accounts, which can cause heavy damage on electronic devices and smartphones.

In the latest bout of malicious applications, UAE governments are currently warning residents to be vigilant when it comes to opening anonymous files on WhatsApp.

Additionally, it included that PDF malware accounted for a substantial portion of cyberattacks launched over the last couple of decades, and encouraged citizens and establishments to get backup databases separate from the world wide web.

The TRA Computer Emergency Readiness Team earlier declared a total of 615 cyberattacks against authorities, semi-government and private business entities in the UAE were blocked during the first ten months of 2017.

"Cyberattacks try to deface and block government sites, such as denial of service, hacking, deception, fraud, and identity and record theft," said the TRA.
