A security flaw in Kaspersky Antivirus software has been discovered that could expose millions of users to hacks. The flaw was discovered by German security researcher Ronald Eikenberg, who found that Kaspersky was injecting JavaScript code into websites.

If exploited by malicious actors, this code could act as a digital spy, tracking users' browsing activity and potentially stealing their personal information.

Eikenberg's research suggests the issue may have been present for a significant period, potentially since 2016. This raises concerns that millions of unsuspecting users might have been exposed. The potential consequences are dire.

Cybercriminals could leverage this vulnerability to track a user's online movements and steal sensitive data like passwords. In a worst-case scenario, they could even install malware on compromised machines, giving them complete control over the system.

Kaspersky Labs has acknowledged the issue and released a patch in their latest software update. However, this doesn't eliminate the risk.

Users who haven't updated their software remain vulnerable. Kaspersky users must update their software immediately to benefit from the security fix and mitigate the risk of being targeted by malicious actors.
