Security experts are warning against an easy-to-weaponize security vulnerability affecting a variety of Zyxel firewalls. There are approximately 42,000 instances of Zyxel web interfaces exposed to the internet, leaving out vulnerable VPN implementations (which means the actual count is even higher). Moving on. A cryptocurrency phishing and scam service known as Inferno Drainer has made headlines for pilfering more than $5.9 million worth of assets from roughly 5,000 individuals. The extensive scope and impact of the operation highlight the urgent need to combat cryptocurrency-related scams.
A number of malware stains have been reported by security researchers at ASEC. Cybercriminals were found propagating DarkCloud, ClipBanker, and StrelaStealer malware in two separate email campaigns. StrelaStealer is being used against Spanish users.

Zyxel flaw can be abused, PoC out
A recently patched command injection flaw in various Zyxel firewalls could potentially be exploited in real-world attacks, stated Rapid7 researchers. The flaw, identified as CVE-2023-28771, affects some versions of Zyxel APT, USG FLEX, and VPN firewalls and Zyxel ZyWALL/USG gateways and firewalls. Moreover, the researchers have shared a technical analysis and a Proof-of-Concept (PoC) script that demonstrates the vulnerability and enables the execution of a reverse root shell.
