Cybercriminals have pushed smartphone attacks to record highs during 2024. A new paper from Kaspersky reveals that these assaults, known as Trojan banker attacks, shot up 196% compared to the previous year. Reports mention more than one million instances of this malware in 2024, rising sharply from around 420,000 in 2023.
In total, 33.3 million strikes involving malware or unwanted software targeted mobile devices worldwide. Ad-based threats led the pack at 57%, but Trojan bankers drew extra attention because they tripled in volume, showing a strong interest in seizing online banking logins and card details.
Phones running the Android system took the hardest hit. Attackers often trick people into installing harmful apps through text messages, chat platforms, or deceptive websites. Once these apps take root, they gather financial data, placing users at risk of fraud and identity theft.
How Do Malicious Groups Steal Private Banking Details?
Attackers use smart tactics to fool the public. They may send harmful attachments disguised as urgent files or direct people to web pages laced with dangerous code. Sometimes they hijack messaging accounts that belong to friends, prompting trust in what appears to be a normal link.
Tricks often involve big headlines. That tactic prompts fast clicks and lowers caution. A single tap can open the door to hidden bankers that drain funds or collect information for resale.
Reports from Kaspersky Digital Footprint Intelligence say 26 million Windows-based devices were compromised between 2023 and 2024 by infostealers. This threat sweeps up passwords, bank card data, and other items, then sells that haul on underground sites. Although Trojan bankers target mobile users, both types of malware share a common goal: easy profit.
Some criminals have cut back on crafting unique malware and concentrate on sending the same dangerous files to huge numbers of targets. This increases infection rates, making it even more important for everyone to stay alert.

What Makes Infostealers So Harmful?
Infostealers hunt for passwords, payment records, and more. Device owners might see odd logins or unusual app activity, but the malware often runs silently. Criminals then misuse stolen details or post them on shady websites, placing finances and personal data at risk.
Popular variants such as Redline, RisePro, and Stealc have been flagged in research. RisePro jumped from 1.4% of infections in 2023 to over 22% in 2024, while Redline still leads at more than 30%. They commonly pose as game add-ons or software cracks.
Which Actions Can Cut Down Threats From Malware?
Smart downloading habits are the first line of defense. Official stores are safer, though none can claim perfection. Checking user ratings and developer details can catch bad programs before they take hold.
Regular software and security updates are also critical. Patches often block new tricks. An effective antivirus can detect hostile behaviour and protect data right away.
Permissions matter as well. A flashlight app, for example, should not ask for contact access. Any odd requests may signal danger. Scammers often count on sloppy oversight, so it helps to study an app’s demands.
Two-factor authentication and solid passwords place further security. Changing logins at the first hint of trouble can prevent further damage. Banks also encourage reporting of odd transactions right away. Fast action can stop a breach from spiralling out of control.
Kaspersky’s report shows that phone-based banking threats are not slowing down. People who use mobile devices for shopping or payments should stay aware of the dangers.
