Vietnamese banks warn iPhone users of Coruna and DarkSword malware

Major Vietnamese banks, including Vietcombank, VietinBank, BIDV, and Agribank, have issued urgent warnings regarding Coruna and DarkSword malware targeting iPhone users. These malicious tools exploit vulnerabilities in iOS operating systems to steal passwords, OTP codes, and personal data.

Security researchers, including Google Threat Intelligence Group, iVerify, and Lookout, identified these threats. Coruna targets iOS versions 13 through 17.2.1, while DarkSword exploits vulnerabilities in iOS 18.4 through 18.7. The malware can infect devices simply through visits to compromised websites or malicious advertisements.

In addition to the Big 4 banks, ACB has also reported these cyberattacks in Vietnam. Financial institutions are advising customers to immediately update their devices to the latest iOS version, avoid suspicious links, and refrain from downloading files from untrusted sources to mitigate the risk of identity theft and financial fraud.
