Mobile devices, like desktop computers, have software and Internet connectivity. On mobile phones, malware (malicious apps) and malicious websites can achieve the same goals (stealing data, encrypting data, etc.) as on traditional computers.
Apps that are malicious come in a range of shapes and sizes. Trojans, which also undertake ad and click scams, are the most popular types of malicious mobile apps.
Ransomware on mobile devices
Mobile ransomware is a specific sort of mobile malware, however as the use of mobile devices for business has grown, it has become a more widespread and dangerous malware variation. Mobile ransomware encrypts files on a mobile device and then demands a ransom payment in exchange for the decryption key, which allows access to the encrypted data to be restored.
Phishing
Phishing is one of the most popular forms of cyber-attack. The majority of cyberattacks start with a phishing email that contains a dangerous link or a malware-infected attachment. Phishing attempts on mobile devices use a range of methods to send links and malware, including email, SMS messaging, social media platforms, and other apps.
In fact, while most people think of emails when they hear the word 'phishing,' they aren't even close to being the most common phishing vector on mobile devices. Emails, in fact, account for only 15% of mobile phishing attacks, trailing messaging, social networking, and 'other' apps (not social, messaging, gaming, or productivity).
