EU court adviser says banks must immediately refund phishing victims

www.bleepingcomputer.com · 4 months ago

An advocate general of the Court of Justice of the EU has issued an opinion stating banks must immediately refund customers for unauthorized transactions, even if the customer’s negligence contributed to the fraud. This ruling stems from a case involving a customer who fell victim to phishing, entering their credentials on a fraudulent website resembling their bank’s login page. Banks can seek to recover losses from customers if gross negligence or intent is proven, requiring them to take legal action. The opinion is not a final ruling but serves as a recommendation for the court.

Hackers abuse .arpa DNS and ipv6 to evade phishing defenses

www.bleepingcomputer.com · 4 months ago

Cybercriminals are exploiting the.arpa domain and IPv6 reverse DNS systems to create more effective phishing campaigns. Attackers are reserving IPv6 address space and then configuring DNS records within those ranges to point to phishing sites, bypassing traditional domain reputation checks. This technique involves using seemingly legitimate DNS providers like Hurricane Electric and Cloudflare, and the.arpa domain’s lack of typical registration data further hinders detection. The phishing emails use images linked to these attacker-controlled reverse DNS names, redirecting victims to phishing sites after a validation process.

A use-after-free vulnerability in the Linux packet socket subsystem, tracked as CVE-2025-38617, affects Linux 2.6.12 through 6.15 and allows an unprivileged local attacker with CAPNETRAW to achieve full privilege escalation and container escape. Attackers exploit a race between packetsetring and packetnotifier to corrupt pgv pointers in TPACKETV3 ring buffers and then mmap those addresses to obtain arbitrary kernel memory access. The exploit corrupts simplexattr objects on tmpfs to build leak and read write primitives, bypasses mitigations including CONFIGRANDOMKMALLOCCACHES and CONFIGSLABVIRTUAL by reusing the same allocation call site, and uses staged techniques to bypass KASLR and patch syscalls to gain root. The vulnerability was fixed in kernel version 6.16 with a two line commit.
