Trezor warns of a suspected crypto-theft implant in a Trezor Safe 5 sold by reseller CryptoBilis in Southeast Asia. An Indonesian buyer found an extra board with a cellular module and antenna between the main board and screen, apparently able to read the recovery phrase and send it over mobile networks. Trezor has not examined the device, advises moving funds to a new wallet for any CryptoBilis purchase since March 2026, and notes a similar Ledger implant was confirmed.

It analyses FAEST's compute-heavy operations, builds them into hardware blocks, and adds an L1-EM-fast variant. The authors report at least 98% lower equivalent area-delay product than the recent complete SDitH design at the same security level.

Presents the first DPA-style power side-channel attack framework against VOLE-in-the-Head signature schemes, targeting the secret witness whose recovery enables forging signatures on arbitrary messages. It analyzes leakage from sensitive intermediate values in VOLE correlations and proposes six attack classes (two vertical, four horizontal) on FAEST and SDitH, both in NIST's third round of additional signatures. Attacks are validated with simulated leakage under varying noise and real measurements on three ARM Cortex-M4 devices.

Rekt write-up on LTE-equipped hardware implants found in Ledger Nano X and Flex wallets sold through resellers such as CryptoBilis and MediaMarkt. The implants read the recovery phrase off the screen during setup and exfiltrate it over an eSIM/LTE modem, so Ledger's Genuine Check and Secure Element never detect them. It covers the teardown timeline (Joe Grand, Mark Karpelès, a Japan-based researcher), the 47-minute multi-chain drain (Bitquery estimates about $102M across 324 wallets, unverified by Ledger), the laundering path via USDD, THORChain, Tornado Cash and Zcash, the CryptoBilis ownership change, and the failure of "authorized reseller" trust.

Three attacks: a profiling attack (97.2% accuracy over 50 medical/privacy keywords), a hidden-state reconstruction attack predicting tokens from the 128k vocabulary (94.3% on profiled classes; 67% of unseen words ranked in top 100), and a hidden-state inversion attack reconstructing prompts semantically. Shows that local edge inference does not guarantee confidentiality of tokens and inputs.

Presents the first fixed-point FN-DSA (Falcon) signer for microcontrollers, using 32.64 arithmetic in constant-time Cortex-M4 assembly for Falcon-512 and Falcon-1024. Techniques that keep reciprocals, inverse square roots and small constants wide and round once at the consumer restore the precision lost by naive fixed-point. Measured precision supports about 2^99.7 (Falcon-512) and 2^96.7 (Falcon-1024) signing queries per key, against about 2^61.5 and 2^58.7 for double precision and the 2^64 target. The signer needs about 45% fewer cycles than double-precision emulation, at the cost of signing RAM rising from 59n to 83n bytes. The paper also shows which implementation choices lift double-precision c-fn-dsa above 2^64, derives Falcon-1024 key-generation bounds (72.3% of keys accepted vs 8.5% with the Falcon-512 values), and gives recommendations for the fixed-point FN-DSA NIST plans.

It shows that SGX's small trusted client memory lets the position map recursion be shrunk to ≤3 levels, making constant-access hash tables beat Θ(log n) tree traversal, and derives via large-scale simulation the concrete padding parameters needed for "double obliviousness" (bounding hash-table rebuild probability to ≤2^-40) that prior ORAM literature lacked. Their SGX implementation reports up to 20x faster lookups and 12x faster inserts than oblivious-tree baselines.

It details an asymmetric task-isolation design pinning crypto to Core 1, a heap-auditing methodology for FreeRTOS's heap_4.c allocator tracking key-state allocations across DRAM, and an analytical latency model of CPU stall overhead caused when side-channel masking forces secret polynomial shares to spill to external Octal-SPI PSRAM during non-sequential Cooley-Tukey NTT strides.

This IACR ePrint paper (published TCHES 2027) presents a new cryptanalysis technique for the Lattice Isomorphism Problem that embeds LIP into a shortest-vector-problem instance on a different lattice than the one used in Hawk's specification, allowing attackers to integrate "hints" — partial information on the secret key obtained via side-channel attacks or other leakage. Using the LeakyLWEEstimator tool, the authors show Hawk signatures themselves leak exploitable information about the secret key, eroding Hawk-1024's security by roughly 11 bits, and apply the framework to resolve an open side-channel problem from TCHES 2024 plus discuss further fault-injection attack paths. Hawk is a lattice-based signature scheme submitted to NIST's second post-quantum signature call, making this a concrete key-recovery cryptanalysis relevant to PQC migration planning.

Researchers at UC San Diego and INRIA demonstrated a chosen-message oracle attack that forges RSA signatures on a 1,024-bit key held inside a hardware security module (HSM) without ever extracting the key, by disabling the HSM's FIPS mode to get it to sign unpadded/unformatted values roughly 4 billion times and then computing the private-key operation from the responses (1,380 CPU core-years of work). The attack only applies to unpadded RSA signing oracles — standard PKCS#1 v1.5/PSS padding blocks it — so it doesn't threaten Bitcoin/Ethereum (which use ECDSA) but is relevant to anyone auditing HSM key-custody assumptions or RSA-based blind-signature schemes like Privacy Pass. The authors frame it as further classical evidence to accelerate migration away from RSA ahead of the post-quantum transition.

It's positioned as a response to systemic IP-camera weaknesses (default creds, hard-coded keys, unsigned firmware, vendor cloud aggregation) exploited historically by the Mirai botnet and the 2021 Verkada camera-feed breach, and targets regulated buyers newly barred from Hikvision/Dahua/Uniview/Edimax-class vendors under NDAA §889 and 2025-26 FCC enforcement. Its pluggable AI Adapter Contract (Apache-2.0 SDK) lets third parties add detection/LLM capabilities out-of-tree, with correlation-ID audit trails and SHA-256 model fingerprinting for compliance evidence.

A Hackers-Arise tutorial demonstrating use of FALCON (Fast Analysis of LTE on Control Channels), an srsRAN/srsLTE-based tool, together with DragonOS and a LimeSDR/USRP B210 to decode the PDCCH of local 4G/5G cell towers. It explains how capturing DCI, RNTIs, and resource allocation data can be abused for passive traffic interception, subscriber tracking via RNTIs, and targeted denial-of-service by identifying cell capacity limits.

Flipper-IRDB is a community-maintained collection of .ir infrared signal files organized by device type, brand and model for use with the Flipper Zero. Contributors submit CC0-licensed IR captures (TVs, ACs, etc.) following a strict naming/format convention, and the files feed into the Flipper's built-in and community "Universal Remote" firmware features used in IR replay/hardware testing.

PromptZero is a natural-language agent (built on Claude) that controls a Flipper Zero and optional ESP32 Marauder devboard over USB/BLE, generating and deploying RF, NFC, RFID, and HID/BadUSB payloads from plain-English commands — e.g. "make me a Starbucks WiFi captive portal" or "deauth the strongest AP". It ships a risk-tiered tool classification (Low/Medium/High/Critical) with consent gates for high-risk actions, a fail-closed audit log, prompt-injection quarantine for tool outputs fed back to the model, and an MCP server mode that refuses High/Critical tools by default. A `--read-only` flag restricts it to reads/scans for blue-team, forensics, or training use.

Leviathan Security's introductory post in a UEFI reverse-engineering and exploit-development series, explaining the UEFI/PI boot flow (SEC, PEI, DXE, BDS phases), core UEFI data structures (EFI System/Boot/Runtime Services tables), and how UEFI Secure Boot, Intel Boot Guard, and Intel BIOS Guard build a layered chain of trust over SPI flash firmware. It walks through UEFITool screenshots of a real X58I BIOS image and explains known design gaps (e.g., UEFI Secure Boot's implicit trust of SEC/PEI, Boot Guard not blocking SPI read/write) that motivate firmware implants and bootkits, setting up later posts on lab setup, static/dynamic analysis, fuzzing, and exploit dev.
