Failure to patch systems with known vulnerabilities and known fixes is a key problem. For instance, roughly 6% of internet-facing Sophos Firewalls could be exploited using a critical vulnerability that the firm squashed last month, leaving organizations susceptible to RCE attacks. Meanwhile, Roaming Mantis malicious campaigns got a makeover with a DNS changer function, reported Kaspersky. Using this feature, adversaries can illegally manage all communications from devices via compromised Wi-Fi routers.
Malware architects innovate once again! A new strain, dubbed Hook, could be making its way through phishing campaigns, Telegram, or in the form of Google Play Store dropper apps, warned experts from ThreatFabric.
