Boston Scientific left nursing its bottom line after cyberattack
Boston Scientific says its August 25 network intrusion will materially hit third-quarter and full-year sales and earnings, likely missing guidance.
Boston Scientific detected unauthorized activity on its network on August 25 and took systems offline, disrupting order processing and shipping operations worldwide. In an SEC filing, the medical device maker warned of a material impact on Q3 and full-year results, making it unlikely to meet the net sales growth and adjusted EPS guidance issued in July. Its distribution network has been substantially restored, sterilization facilities are operational, manufacturing resumed at most sites, and an interruption affecting cardiac device remote-monitoring activations was resolved. The company has not revealed the attack vector, whether ransomware was involved, or whether data was stolen; no ransomware group has claimed responsibility and the investigation continues.

Revolut Data Breach Via Fake Government Requests – What We Know So Far
Revolut confirmed attackers extracted customer KYC records by sending fraudulent data requests from a spoofed or compromised government agency email domain.
Revolut confirmed a data breach in which an unauthorized party obtained sensitive customer records by submitting fraudulent information requests from an email account on a legitimate government agency domain with valid SPF/DKIM/DMARC authentication. Disclosed data could include full names, dates of birth, passport or driving-license copies, onboarding facial images, IBANs, account statements, withdrawal records, and complete transaction histories including Bitcoin activity. Crypto investigator ZachXBT assessed the operation targeted high-net-worth users, while a threat actor using the name 'IAmNotAVillain' claimed Italian law-enforcement departments were compromised over six months with 147 GB of material, claims that remain unverified. Revolut says only a limited number of customers were affected, blocked the email address, and notified regulators and affected customers, stating its systems and funds were not compromised.

Thomson Reuters Court Software Breach May Have Exposed SSNs and Sealed Data
Unauthorized access to Thomson Reuters' C-Track court platform may have exposed SSNs and sealed records across 11 US states, USVI, and Ontario.
Thomson Reuters' West Publishing disclosed that an unauthorized party obtained files from the C-Track court case management platform starting in March 2026, with access to one environment running from March 1 through June 29, 2026 per Montana's account. Notices name roughly 24 court bodies across 11 US states, the US Virgin Islands, and Ontario, including appellate courts in Minnesota, Ohio, Montana, and Pennsylvania. Exposed data may include names, Social Security numbers, driver's license numbers, dates of birth, medical and health insurance information, and confidential or sealed court records. The company is offering 12 months of Experian or TransUnion monitoring, and courts disagree over whether the vendor's backup cloud environment or the production platform was accessed.

The GTA VI leaks are breaking the internet. Security researchers have seen this before.
A hacker or insider leaked GTA VI gameplay footage before launch, triggering Take-Two DMCA subpoenas against Discord, Google, Microsoft and X.
The persona "CyberLeek" published stolen Grand Theft Auto VI gameplay footage and a manifesto, in what experts call a familiar data extortion playbook with monetization via watermarks, crypto wallets and a memecoin. Take-Two Interactive obtained DMCA subpoenas against Discord, Microsoft and X, and sent copyright notices to Google, treating the case like an insider threat investigation. GTA VI is projected to earn $3.3–5.2 billion in launch-week sales, raising financial and reputational stakes. Related leak websites went offline after the subpoenas.

Revolut Data Leak May Trace Back to Compromised Italian Government Accounts
Attackers using a compromised Italian government PEC account impersonated law enforcement to obtain data on ~680 Revolut customers.
Revolut confirmed its systems were not breached; fraudulent data requests came from a compromised PEC mailbox tied to the Prefecture of Reggio Calabria on the pec.interno.it domain. Per the Financial Times, roughly 680 customers had identity documents, addresses, banking information, verification selfies and cryptocurrency transaction histories exposed. Researcher Korra of Duel described a 'spray and pray' operation using hundreds of crypto transaction IDs and fraudulent European Investigation Orders. Threat actor IAmNotAVillain claims six months of access and 147 GB exfiltrated from Italian law-enforcement systems, though this remains unverified.

Leaks, data breaches, and ransom notes: The worst hacks of 2026 so far
TechCrunch's 2026 roundup covers SSA data exposure, Iranian water-utility attacks, Klue breach hitting ~200 firms, and Meta AI chatbot account hijacks.
TechCrunch's mid-year roundup highlights a whistleblower claim that DOGE uploaded a live Social Security database copy to an unsecured third-party server, which House Democrats called potentially the largest US breach in history. CISA reported Iranian hackers targeted over 100 US water providers over the summer, while Russian-linked attacks hit Polish, Swedish, and Norwegian energy and water infrastructure. Market research firm Klue was breached via a stale 2022 pilot credential, exposing cloud keys of ~200 customers including Jamf, HackerOne, and LastPass to extortion gang Icarus. Separately, tens of thousands of Instagram accounts were hijacked by abusing Meta's AI chatbot to trigger password resets to attacker-controlled emails.

Extortion Group FulcrumSec Claims 86GB Manchester Airports Data Theft
Extortion group FulcrumSec claims stealing 86GB of Manchester Airports Group data, exposing 8.7 million customers' personal and booking details.
Manchester Airports Group disclosed a breach on August 27 affecting parking, lounge, Fast Track and WiFi registrations at Manchester, London Stansted and East Midlands airports, impacting 8.7 million customers, most exposed only email addresses. FulcrumSec claims it stole about 86GB via airport-specific Iterable API credentials exposed in client-side JavaScript, including a 21.5GB Manchester export with booking histories, marketing data and nearly 200,000 records on upcoming 2026 travel. BleepingComputer verified sample records against a real traveler's Fast Track history; MAG declined to address the group's specific claims. Researchers warn the combination of UK postcodes, vehicle registrations and booking details could enable convincing targeted phishing, and MAG says no payment card or banking data was exposed.

Mozilla Revokes Firefox and Thunderbird Linux Signing Key After Key Lands in Private Repo
Mozilla revoked the Firefox and Thunderbird Linux RPM signing subkey after an unencrypted copy landed in a private repo; no unauthorized access found.
Mozilla revoked the OpenPGP signing subkey (fingerprint 09BE ED63 F346 2A2D FFAB 3B87 5ECB 6497 C1A2 0256) used for Firefox and Thunderbird Linux downloads after an unencrypted copy was committed to one of its private repositories, citing reason code 2, 'key material has been compromised.' Audit records showed no sign of unauthorized access, and a replacement subkey (827E 6586 0867 9618 CD34 9F93 678E 455D 7676 7AA3) valid until August 5, 2028 was published. Users who verify signatures manually or install from Mozilla RPM packages may need to import the new key and remove the old one. The rotation came roughly seven months ahead of Mozilla's usual two-year subkey cycle.
