Post-quantum migration gets harder when every user holds a key
Quantus CEO Christopher Smith discusses post-quantum migration pitfalls, including oversized keys breaking IPsec, SSH and TLS, and hard-to-migrate blockchain user keys.
Quantus CEO Christopher Smith describes post-quantum migration findings from banks and hospitals, including forgotten default passwords, orphaned admin keys held by former employees and hidden password hashes on user devices. Larger post-quantum keys and signatures break size assumptions in IPsec, SSH, TLS and libp2p, while migrating blockchain user keys remains hard because every user must act. He argues boards should fund quantum migration like insurance by quantifying cryptographic failure risk, and warns a silent quantum break would be difficult to detect from outside.

PDoS: A Profitable Denial-of-Service Attack against Proof-of-Work Blockchain Liveness
PDoS attack disrupts Proof-of-Work blockchain liveness profitably by combining miner deterrence signals with parasitic revenue extraction from victim pools.
PDoS is a hybrid incentive-driven denial-of-service attack that combines block header signal deterrence with parasitic revenue extraction from a victim pool's share-reward mechanism. By subsidizing attack costs through the victim pool, it lowers the hash-power threshold required to induce rational miners to shut down, unlike prior attacks such as BDoS that demand sustained attacker losses. The authors show a counterintuitive result: in high-fee or high-MEV environments, higher block value increases the attacker's parasitic revenue and can push the attack past break-even into a self-sustaining or even profitable regime. PDoS is claimed as the first attack demonstrating that disrupting PoW blockchain liveness can be economically self-sustaining.

How much of F-Droid is LLM generated?
A FOSS maintainer manually graded 102 F-Droid apps from the September 12, 2026 update batch, finding many show signs of LLM-generated code.
A student and FOSS app maintainer reviewed 102 apps pushed to F-Droid on September 12, 2026, assigning each a three-tier rating for likelihood of LLM-authored code (mostly AI >50%, hard to say/mostly human, no signs of AI). The heuristic relies on commit aesthetics, README and branding style, and the presence of agentic infrastructure like Claude Code or Codex, which automatically places an app in the 'mostly AI' tier. Example ratings include Amber (Nostr event signer) as mostly AI, and Aria for Misskey as showing no AI signs. The author stresses reliable detection of LLM-generated code from text alone is impossible, so ratings are approximate.

There Is No Patch Tuesday on the Blockchain: Why Solidity Developers Need Fusion-Grade AppSec Before They Deploy
Checkmarx argues Solidity developers need pre-deployment AppSec because disclosure-to-weaponization time has collapsed from 840 days to 1.6 days.
A Checkmarx write-up contrasts traditional software patch cycles with blockchain development, where there is no Patch Tuesday and fixes require on-chain upgrades. It cites stats that median disclosure-to-weaponization time collapsed from 840 days to 1.6 days and that 80% of exploitations now occur on or before disclosure day. The piece advocates fusion-grade application security for Solidity teams before contracts deploy.

Risky Bulletin: Dutch intel services to get extensive new powers
Netherlands proposed a bill granting AIVD and MIVD expanded warrantless tapping, faster hacking powers, and forced data disclosure, citing Russia, China, and Iran threats.
The Dutch government introduced a bill greatly expanding surveillance powers of intelligence agencies AIVD and MIVD, allowing up to one year of tapping without pre-approval and simplified hacking operations against 'foreign adversaries'. Agencies could compel Dutch companies or citizens to provide data under threat of charges, share data with the private sector, and oversight bodies would merge into a new CTT board. The bill follows similar overhauls in Ireland, Germany, and France after Russia's invasion of Ukraine. The newsletter also reports Moonwell hacked for $8.7M, a Cosmos EVM bug exploited for ~$3M, ShinyHunters listing McKesson with claimed hundreds of millions of records, and a pro-Kremlin DDoS claim against Norway's government network.

House passes bill to equip local law enforcement with scam-fighting tools
The U.S. House passed the GUARD Act, letting local law enforcement use federal grants to investigate financial scams and trace stolen cryptocurrency.
The bipartisan GUARD Act (Reps. Zachary Nunn, Scott Fitzgerald, Josh Gottheimer) passed the House, allowing existing DOJ grant funds to be used for fraud analysts, victim-support training, blockchain tracing software, and financial-information sharing with law enforcement. It addresses scams like pig butchering, often run by transnational criminal groups overseas; Americans lost a record $11.4 billion to crypto-related fraud in 2025, including $8.6 billion in investment fraud. Senators Katie Britt and Kirsten Gillibrand introduced a Senate companion in July 2025, and the House also passed a bill retroactively eliminating the 'scam tax' on stolen funds for 2021-2025 victims.

Guppy: Efficient Light Clients via Recursive Zero-Knowledge Proofs
Guppy lets blockchain light clients verify full state via recursive zero-knowledge proofs without validators maintaining state commitments, processing thousands of updates per second.
Guppy is a light-client protocol in which validators commit only to state updates while an off-chain, untrusted service secured by recursive zero-knowledge proofs maintains a verifiable Merkle tree over the full state. A hash-chain commitment moves validator signature verification out of the proving circuit, and a parallel recursive proving pipeline keeps latency growth logarithmic with throughput. A Plonky2-based implementation maintains a tree of size 2^30 while processing thousands of updates per second, adding only 2-4 seconds of latency without increasing block-construction complexity.

On Identifying Sound Conditions for Frontrunning Resistance
Researchers formally define smart-contract frontrunning resistance, showing 55% of 393 audited vulnerabilities escape state-of-the-art detection, and find two undisclosed Ethereum flaws.
The paper gives the first formal definition of frontrunning vulnerability for smart contracts, grounded in how honest users interact with contracts rather than contract code alone. In a large-scale study of 287 smart contract audits, 55% of the 393 vulnerabilities reported by leading auditors fall outside the scope of state-of-the-art dynamic detection criteria. The authors present a sound algorithm for synthesizing secure interaction conditions and apply it to real-world contracts, uncovering previously undiscovered vulnerabilities in two Ethereum contracts.

U.S. Sanctions Iran-Linked Hackers Behind Critical Infrastructure Breaches
U.S. Treasury sanctioned nearly 60 Iran-linked entities, including MOIS-affiliated Mabna Institute hackers behind breaches of U.S. critical infrastructure and millions in crypto theft.
The U.S. Treasury launched Operation Economic Outcast, designating nearly 60 Iran-linked entities, individuals, and vessels across nuclear, missile, oil, cyber, and digital asset networks. Five sanctioned individuals are members of the Tehran-based Mabna Institute indicted last week; three allegedly breached and exfiltrated data from U.S. energy, defense, healthcare, IT, and financial organizations since late 2023. TRM Labs traced roughly $16.8 million across 30 wallets tied to the members, and the State Department announced a reward of up to $10 million. The action follows Iranian hacking of FBI Director Kash Patel's email and attacks on over 30 U.S. water and wastewater utilities.

Risky Bulletin: White House lets private companies carry out offensive cyber ops
A White House memo directs DHS to create a program letting vetted private companies conduct US-government-directed offensive cyber operations against cybercrime.
A presidential memo tasks the DHS National Coordination Center with building a program, under DOJ and DHS oversight, through which private-sector companies can conduct offensive cyber operations against large-scale cybercrime organizations. Requirements include secure facilities, vetted personnel, a $1 million escrow for damages, and written approvals co-signed by DHS and DOJ executive directors. The program must launch within 60 days, around October 11, expanding a March executive order targeting scam compounds, ransomware, and other large-scale cybercrime.
