Tech Today: Experts warn that worldwide cyber-attack was about data, not money

The Petya malware variant that hit businesses around the world may not have been an attempt to make money, suspect security experts.

Yesterday the Trinidad and Tobago Police Service voiced its concern about the introduction of Ransomware in this country, adding that it has already affected 7 local businesses and individuals.

Ransomware is a type of malware that prevents or limits users from accessing their system, either by locking the system’s screen or users’ files.

The malicious program demanded a payment to unlock files it scrambled on infected machines.

However, according to the BBC, a growing number of researchers now believe the program was launched just to destroy data.

Experts point to “aggressive” features of the malware that make it impossible to retrieve key files.

Security firm Comae, described the variant as a “wiper” rather than straight-forward ransomware.

They wrote that the goal of a wiper is to destroy and damage, adding that the ransomware aspect of the program was a lure to generate media interest.

Although the Petya variant that struck this week has superficial similarities to the original virus, it differs in that it deliberately overwrites important computer files rather than just encrypting them.

The security firm said that the 2016 Petya modifies the disk in a way where it can actually revert its changes, whereas, 2017 Petya does permanent and irreversible damages to the disk.

So today’s tech tip is to ensure you backup all your files on your system.
