‘White hat’ hackers take $47 million bounty after $320 million crypto theft
Hackers withdrew $320 million in bitcoin from Liquid Network, negotiated on-chain, returned $266.5 million and kept a $47 million reward.
Purported white-hat hackers withdrew 4,000 BTC (about $320 million) from Liquid Network's own wallet, one of the largest cryptocurrency thefts of 2026. Over roughly 12 hours of public on-chain negotiation with operator Blockstream, the hackers returned $266.5 million in bitcoin and kept 598.5 BTC (about $47 million), claiming it as a reward for uncovering a bug. Blockstream deployed updated software and paused deposits and withdrawals while experts traced the flaw to the Elements sidechain framework. April thefts of $290 million from Kelp and $280 million from Drift, attributed to North Korean hackers, were previously 2026's largest.

Trezor Says ShipMonk Breach Exposed 67,000 U.S. Customers' Data It Said Was Deleted
Trezor disclosed the ShipMonk breach exposed data of 67,000 additional US customers, reportedly by ShinyHunters exploiting a Metabase zero-day SQL injection, CVE-2026-72898.
Trezor disclosed that a breach at shipping provider ShipMonk exposed names, email addresses, phone numbers, shipping addresses, and order numbers of 67,000 additional US customers, with orders dating November 2019 to August 2021 despite written assurances the data had been deleted. This adds to the 13,689 customers previously disclosed after ShipMonk informed Trezor of unauthorized access on August 10, 2026. According to Holborn, the ShinyHunters extortion gang is behind the breach, which began with zero-day exploitation of CVE-2026-72898 (CVSS 10.0), a critical SQL injection flaw in Metaboobase analytics software Metabase. Trezor says hardware wallet security is unaffected but warns customers to watch for phishing and social engineering; ShipMonk has not publicly acknowledged the incident.

SafePal latest crypto hardware wallet maker affected by breach, with nearly 40,000 impacted
SafePal confirmed nearly 40,000 customers' order data was stolen, the third hardware wallet maker breached in a month after Trezor and Coinkite.
SafePal confirmed a breach exposing names, emails, shipping addresses, phone numbers, and purchase details of customers who ordered between March 2, 2025 and April 11, 2026, caused by a flaw in an order-tracking plugin.

ClickFix attacks infecting PCs and Macs are going viral
ClickFix social engineering attacks are spreading widely, delivering malware to Windows and macOS users by tricking them into running malicious terminal commands that bypass Gatekeeper.
BlueVoyant reports the Lorem Ipsum malware operation pivoted to ClickFix in late May 2026, dropping code-signing infrastructure and broadening its victim pool from Microsoft Teams searchers to anyone browsing a compromised website. Jamf and independent researchers documented macOS ClickFix variants that bypass Gatekeeper protections. Cisco Talos observed attackers abusing published Google Sheets for control traffic, while Netskope counted 5,400 sites beaconing to one campaign; Sandworm has separately hosted control infrastructure in blockchain smart contracts.

KREMLIN Banking Malware Infects Over 1,500 Systems With Malicious Chrome Extension
Elastic tracks KREMLIN banking malware that used fake Brazilian bank JavaScript lures to deploy malicious Chrome and Edge extensions on 1,515 systems.
Elastic researchers tracked the KREMLIN banking malware operation across seven campaigns over 15 months, infecting 1,515 systems, 98.75% of them in Brazil. Portuguese-language lures posing as bank records and invoices deploy a hostile 'AVSync' extension into Chrome and Edge profiles that harvests passwords, session cookies, keystrokes and screenshots. Loaders check for sandboxes, create scheduled tasks and fetch fresh infrastructure from an Ethereum smart contract; a network canary takeover temporarily disrupted infections.

Risky Bulletin: BEC campaign steals €35 million from French notaries
Hackers stole over €35 million from 500+ French notary offices in a four-year BEC campaign; ANSSI spent two years helping evict the attackers.
A business email compromise campaign breached more than 500 French notary offices — about 7% of all French notaries per the Conseil Supérieur du Notariat — over four years, stealing more than €35 million by phishing initial access and silently modifying wire transfer details. France's cybersecurity agency ANSSI worked for two years behind the scenes to help notaries remove the persistent attackers, who had deep access; officials also feared hackers could issue fake notarized acts such as marriage certificates or forged real estate deals. No forged documents have been found so far, but notaries have added two-factor authentication and in-person requirements for banking details, and banks added extra checks in 2024. The newsletter also notes other incidents, including a $320 million Bitcoin extraction from Blockstream's Liquid Network and a JetBrains Cadence breach via TeamCity servers.

SafePal Says 39,798 Customers Hit by Data Breach
Crypto wallet maker SafePal disclosed a breach exposing order data of 39,798 customers via a plugin authorization flaw; keys and seed phrases unaffected.
SafePal, a Singapore-based cryptocurrency security company, said an authorization flaw in an order-tracking plugin let attackers access order records placed between March 2, 2025 and April 11, 2026. Exposed data includes names, emails, addresses, phone numbers, and purchase details for about 39,798 customers, while seed phrases, private keys, wallet passwords, and payment data were not exposed. A threat actor advertised the same dataset on a cybercrime forum, and affected customers were notified by email on August 16. The company patched the flaw, reduced data retention to 90 days, and removed over 30 fraudulent phishing websites.

Attackers Turn Trusted Node.js Runtime Into Malware Delivery Tool in Targeted Attacks
Symantec reports multiple threat actors, including KongTuke, abusing the trusted signed Node.js runtime and blockchain C2 (EtherHiding) to deliver backdoors in targeted attacks.
Symantec's Threat Hunter Team (Broadcom) reports that since February 2026 attackers have used the legitimate signed node.exe binary and interpreted scripts to deliver implants while evading signature-based detection, hitting government departments, technology companies, and hotels. One intrusion at an Asian technology firm (March 23–July 25, 2026) used ClickFix social engineering, the official Node.js installer, and EtherHiding to fetch commands via the Ethereum blockchain after AdaptixC2 and Cobalt Strike attempts were blocked. Related chains involve KongTuke (Woodgnat) using ModeloRAT, Mistic, NexShield, and GateKeeper, plus C2Looper, AsukaStealer, and EtherRAT; GuidePoint Security separately linked a fake-CAPTCHA ClickFix campaign to at least 31 compromised organizations using the Polygon blockchain as a dynamic C2 address book.
