Joint Cyber Command Issues Alert on New Malware, the ‘Infostealer’

• A new malware has been identified, which infiltrates our devices through malicious emails

The Joint Cyber Command has issued a warning about a new type of malware currently being deployed across the network. This is the ‘infostealer’, a spyware—computer virus—whose primary function is to steal passwords, banking details, and other sensitive information. The most common methods for this malware to infiltrate a device are through malicious emails. These emails contain bait files disguised as reliable free software downloads, infected websites, or the use of weak and commonly used passwords—those lacking uppercase letters, lowercase letters, numbers, and special characters.

Specifically, the ‘infostealer’ virus steals personal and banking data, which allows others to impersonate us. This stolen information can be sold on the dark web—an online platform similar to the internet but with a more complex interface, where illicit activities can take place. It is particularly important that we remain aware of the dangers present on the internet.

This new digital reality has made life easier, with everyone connected through the various tools it offers. However, it is a double-edged sword—it simplifies many aspects of life, but misuse can lead to serious repercussions. For this reason, the Joint Cyber Command aims to raise awareness about the dangers found online and how to prevent them. 

Lastly, it is recommended not to use or store work-related credentials neither on personal devices, nor to mix work security passwords with personal ones. If in doubt, individuals can always contact the Chief Information Security Officer (CISO) of their company or institution, or call the National Cybersecurity Institute (INCIBE in Spain) through their helpline at 017.
