The count by Yokohama-based Macnica includes attacks without data encryption and already exceeds the 228 cases recorded in all of 2025, a new annual record. Among 100 Japanese firms surveyed by Proofpoint, the ransomware infection rate jumped to 73% in 2025 from 38% in the 2023 survey, the largest increase among 11 comparable countries — and about 40% of organizations that paid ransoms failed to recover data or regain access after a single payment, many facing additional demands.JapanCybersecurity https://sagire.online/wire/2690b9e7/https://sagire.online/wire/2690b9e7/Wed, 04 Nov 2026 22:21:00 -0300Several regional facilities of the French Blood Establishment (EFS) were affected on November 2 by a cybersecurity incident that hit cold storage room monitoring and control systems, according to the French Health Ministry. The situation is now under control and the safety of blood supplies was preserved thanks to monitoring and alarm systems — no health impact has been identified and no blood products have been lost, the EFS said, with collection and hospital deliveries continuing normally. Hackers accessed control units for fridges containing blood samples and programmed them to raise temperatures to 110°C, according to local media. The incident followed attacks that forced stores in eight European countries to throw away vast quantities of food after hackers tampered with their fridges on Monday.FranceEuropeCybersecurity https://sagire.online/pyongyang-denies-binance-heist/https://sagire.online/pyongyang-denies-binance-heist/Wed, 04 Nov 2026 21:56:00 -0300The Federal Bureau of Investigation says [North Korea took more than $6 billion from Binance](https://www.fbi.gov/investigate/cyber/alerts/2026/north-korea-responsible-for-6-billion-binance-attack).

Technology experts warn that creating a new organization alone does little to address the deeper problem of complacency, with businesses and government agencies viewing tighter cybersecurity as an unnecessary expense until a serious breach occurs.South KoreaCybersecurityEast AsiaTechnology https://sagire.online/wire/3212a7e9/https://sagire.online/wire/3212a7e9/Wed, 04 Nov 2026 15:21:00 -0300A cybersecurity incident altered the operating parameters of cold chambers at supervision and control installations in three regional sites of the Établissement français du sang (EFS) on Monday. According to Le Canard Enchaîné, the chambers that store donor samples at -30 °C were set to 110 °C. The EFS said no health impact had been identified and that there were no blood product losses to report. Coolworld, the refrigeration company serving the EFS, said only a limited number of units were affected, through remote monitoring software that relied on a third-party component. The case came shortly after a wave of suspected attacks on supermarket refrigerators and freezers in a dozen European countries, France among them; it is not yet known whether the episodes are linked.FranceCybersecurityHealth https://sagire.online/wire/5f31c94a/https://sagire.online/wire/5f31c94a/Wed, 04 Nov 2026 11:22:00 -0300Ransomware attacks on Japanese companies have more than doubled in five years.JapanCybersecurity https://sagire.online/wire/37bf5e59/https://sagire.online/wire/37bf5e59/Wed, 04 Nov 2026 08:23:00 -0300French authorities said a cyberattack on several blood banks sought to raise temperatures to extremely high levels and was thwarted before it could do any damage to blood products or samples. The French Blood Establishment (EFS) said “temperature and defrosting thresholds were raised to extremely high levels” on Monday at three of its cold-storage sites for plasma, and that no health consequences were identified and no blood products were lost. The attack hit a supplier of refrigeration equipment at three EFS sites. France's national cybersecurity agency and the Health Ministry are investigating the incident. The incident comes after supermarkets in several European countries reported that their fridges and freezers warmed up after being remotely taken over, with tons of spoiled food at a total cost of millions of dollars.FranceCybersecurityHealth https://sagire.online/wire/9ae42842/https://sagire.online/wire/9ae42842/Wed, 04 Nov 2026 08:22:00 -0300The French bank Crédit Mutuel Arkéa, based in Brittany, confirmed it had suffered a cyberattack detected by its services. Its leadership said it took “the decision to temporarily suspend certain transactions in order to secure operations and prevent any new fraudulent movement”. The newspaper Le Télégramme reported that 133 million dollars (118 million euros) disappeared, an amount the bank does not confirm, and Le Monde reported the attack with losses estimated at 118 million euros.FranceCybersecurity https://sagire.online/wire/8954e349/https://sagire.online/wire/8954e349/Wed, 04 Nov 2026 08:22:00 -0300According to the Associated Press (AP), in a text republished by the Boston Globe, Indonesia's military deployed more than 20,000 troops and personnel to Jakarta as authorities investigate an alleged illegal wiretapping operation targeting the president.

According to Reuters, in a text republished by Internazionale, the statement was carried by the state-run KCNA agency, and Kim said there was no need to sit down with “such unreliable and hostile persons,” while Elliptic counted about $2.85 billion frozen or seized from funds that moved through roughly 12,000 wallets and 40,000 transactions across 11 blockchains.North KoreaCybersecurity https://sagire.online/wire/c4ebecb6/https://sagire.online/wire/c4ebecb6/Tue, 03 Nov 2026 18:23:00 -0300Kim Yo Jong, sister of North Korean leader Kim Jong Un, denied the FBI’s accusation that North Korea was responsible for the theft of more than $6 billion in crypto assets from Binance and said she sees “no need” for dialogue with Washington. In a statement published by the official KCNA on Wednesday, the ruling-party director said the accusation showed “US hostile policy” toward North Korea. The rejection comes amid speculation about a possible summit between Donald Trump and Kim Jong Un later this month. Trump said in August that he wanted to meet the North Korean leader later this year, and Pyongyang had not responded to the offer.North KoreaUnited StatesCybersecurityDiplomacy https://sagire.online/wire/055a9585/https://sagire.online/wire/055a9585/Tue, 03 Nov 2026 12:22:00 -0300Binance said hackers used fake job interviews and a compromised internal artificial intelligence tool to breach its systems and drain $6.3 billion in cryptocurrency. An engineer was instructed to download malware disguised as an “assignment” during a second interview, and the code used obfuscation techniques to evade detection. The agencies investigating the case said the hack bore the signs of having been orchestrated by North Korea, and Pyongyang denied on Tuesday that it was behind the theft. The exchange froze $2.85 billion in assets and replenished about 98% of the affected tokens with company funds.North KoreaCybersecurity https://sagire.online/wire/f3292101/https://sagire.online/wire/f3292101/Tue, 03 Nov 2026 09:23:00 -0300An unprecedented leak exposed the personal information of South Korean President Lee Jae Myung, first lady Kim Hea Kyung, senior aides, bodyguards and journalists accompanying them overseas. The breach, reported by local broadcaster KBS on Monday, exposed sensitive personal information belonging to 168 people aboard the presidential aircraft over a period of about five months, including passport numbers and issue dates. The government has launched an investigation and moved to reissue passports for Lee and the first lady, and the presidential office ordered a sweeping review of security protocols for presidential overseas trips. South Korea’s Foreign Ministry is examining the possibility that the leaked document originated from its protocol office, which is responsible for the presidential aircraft’s passenger list.South KoreaCybersecurity https://sagire.online/wire/1d287d17/https://sagire.online/wire/1d287d17/Tue, 03 Nov 2026 09:23:00 -0300A spate of cyber-attacks hit supermarket chains across at least 10 European countries on Monday, prompting European Union (EU) officials to warn of a deliberate attempt to disrupt the food supply chain. Supermarkets reported problems in Belgium, Estonia, Finland, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Germany and Sweden, and the rise in freezer temperatures, reportedly as high as 50°C, forced retailers to discard food. The EU’s food and agriculture commissioner, Christophe Hansen, said the bloc was taking the incidents very seriously and warned of further disruption in the future. In Belgium, dozens of stores reported refrigeration failures and federal prosecutors opened an investigation.European UnionCybersecuritySupply chainsEurope
