We could find the recently leaked North Korean Linux stealth rootkit, but have made it better by completely decloaking the hidden module in Sandfly 5.5.4. Works on other rootkit variants as well like those based on Reptile. Read more at the link below.
Sandfly 5.5.4 has full decloaking of the recently leaked North Korean Linux stealth rootkit module, plus enhanced legacy Linux device support. Get the widest Linux threat coverage without the risk of endpoint agents. Read about the update in the link in this thread.

GPT-5 just casually did new mathematics. Sebastien Bubeck gave it an open problem from convex optimization, something humans had only partially solved. GPT-5-Pro sat down, reasoned for 17 minutes, and produced a correct proof improving the known bound from 1/L all the way to
Claim: gpt-5-pro can prove new interesting mathematics. Proof: I took a convex optimization paper with a clean open problem in it and asked gpt-5-pro to work on it. It proved a better bound than what is in the paper, and I checked the proof it's correct. Details below.

On Volt Typhoon and Salt Typhoon, Rob Joyce @RGB_Lights tells @SangerNYT: "The response from us being on the receiving end of those successful operations was not to...cower because of the cyber power coming at us. It was to get angry and to start to push back."

Google has just used AI and threat intel to foil a zeroday before it could launch. Working from artifacts gathered by GTIG, Big Sleep was used to identify a vuln before actors could ramp up exploitation. It doesn’t get much better than this in intel.

Wow. Spain is putting salt typhoon out of business. They are just going to hand it all to them: Huawei contracted to manage their wiretaps…. https://t.co/h0KwoqLRid

Huawei will manage and store judicially authorized wiretaps in Spain, under a contract that bucks the trend of Western governments restricting use of the Chinese tech company's products and services.

Predatory Sparrow strikes again. This time they drained funds from an Iran-based crypto exchange. Beyond theft, they targeted trust, undermining a key tool Iran uses to evade sanctions. Nobody with options will keep crypto assets there now.
BREAKING 🔴🔴🔴 Israeli-linked hacker group “Predatory Sparrow” wiped out 95% of assets on Iran’s Nobitex crypto exchange. Nobitex was reportedly used by Tehran to evade sanctions through crypto. Wallet balances plunged from $1.8 billion to just $100 million.

Predatory Sparrow’s past cyber attacks on Iranian steel plants and gas stations have demonstrated tangible effects in Iran. Disrupting the availability of this bank’s funds, or triggering a broader collapse of trust in Iranian banks, could have major impacts there.
The hacker group Predatory Sparrow (Gonjeshke Darande), which has previously claimed major cyber operations against Iranian infrastructure, said on Tuesday it carried out a cyberattack that destroyed all data at Iran’s Bank Sepah, a financial institution linked to the Islamic
