Over 1,000 Internet-exposed GitLab servers are still unpatched against a maximum-severity flaw actively exploited in remote code execution attacks. Tracked as CVE-2026-97229, this vulnerability stems from an integer overflow weakness and was discovered in the CI/CD Regular Expression Compiler, which parses and evaluates regular expressions in pipeline configuration files. "GitLab has remediated an issue that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration, due to insufficient regular expression validation," the company explained on October 12 when it released security patches to address the security issue in GitLab Community Edition (CE) and Enterprise Edition (EE) versions 19.4.2, 19.3.5, and 19.2.8.
A new wave of fridge cyberattacks hit supermarket refrigeration systems across five European countries, raising temperatures and causing food losses. A new wave of fridge cyberattacks has affected supermarket refrigeration systems in several European countries. Fridges and freezers suddenly rose in temperature overnight, with some incidents suspected to be caused by hackers. On Monday, November 2, Ahold Delhaize and Colruyt reported an IT incident affecting dozens of stores in Belgium and Luxembourg. Swedish supermarket chains ICA and Coop also reported similar problems. “Ahold Delhaize and Colruyt said on Monday that an IT incident overnight hit fridges and freezers in dozens of stores in Belgium and Luxembourg, while Swedish grocers ICA and Coop reported similar temperature spikes, with one store blaming a cyberattack.” Reuters states. BREAKING: Swedish grocery giant ICA, one of Sweden's largest supermarket chains, says several of its stores have been hit by a cyberattack overnight, causing refrigerators and freezers to be remotely set to 50°C. The incident has likely resulted in large quantities of food… pic.twitter.com/wrcmGHw1qV — GeoInsider (@InsiderGeo) November 2, 2026 “Problems were discovered at several grocery stores in Sweden overnight Monday.” reported Sweden Herald. “We are aware that a limited number of stores were affected by an incident overnight that affected their refrigeration and freezer systems. Ica is providing support in handling the incident, Ica Group press officer Gustaf Nilsson tells TT.” The latest incidents follow a similar wave of fridge cyberattacks in France last month. In mid-October, a large cyberattack hit the refrigeration systems of hundreds of French supermarkets, BFMTV revealed. The attackers targeted equipment from the Danish maker Danfoss that many French stores use to regulate their cold. Fresh and frozen stock was destroyed, and the Paris prosecutor says there were also fires. The method is simple and nasty. Refrigeration systems have a forced defrost function that clears ice buildup, and the attackers appear to have triggered it remotely in a continuous mode, with a temperature setting of 50 degrees. The equipment heated for several hours instead of keeping goods cold, and when staff opened the fridges and freezers in the morning, a sector source told BFM, “a wave of heat” came out. The attack caused fires and food losses. However, cybersecurity consultant Emil Olofsson of Integrity 360 told Swedish news agency TT that temperatures reached 80°C in some cases and several units caught fire. This figure differs from the one reported by police. ICA Kvantum in Sjöbo said on Facebook that a cyberattack caused the refrigeration problems. ICA Hägerstensåsen in Stockholm was also reportedly affected. According to the Sjöbo store, the temperature inside its fridges and freezers rose to 50°C. In Belgium, Delhaize detected unusual temperature increases in its refrigeration systems on Monday. Spokesperson Sarah De Meester said the company is investigating the incident. Stephan Moelans, CEO of Sabcobel, the company that manages Delhaize’s refrigeration systems, told news agency Belga that hackers had switched the units’ evaporators to defrost mode. His office declined to comment to Reuters. Colruyt Group, which operates Spar stores in Belgium through a franchise system, said five stores had suffered attacks on their refrigeration systems. Meanwhile, Belgian newspaper Le Soir reported that dozens of Delhaize and Carrefour stores were affected. UPDATE: REFRIGERATION DISRUPTIONS SPREAD ACROSS EUROPE – SWEDEN AND BELGIUM AFFECTED IN SWEDEN: • At least 6 ICA supermarkets affected by suspected refrigeration system hacks. • Coop has now CONFIRMED that 6 of its stores in central Sweden are also affected. • Freezer… https://t.co/a3oGMrGdmz pic.twitter.com/8Q3CFDDLhT — Coffe Report (@CoffeReport) November 2, 2026 It follows a similar attack in France last month. Police said hackers seized control of the cooling units at hundreds of supermarkets and raised temperatures as high as 50 degrees Celsius (122 Fahrenheit), which caused fires and food losses. Cybersecurity consultant Emil Olofsson of Integrity 360 told TT, Sweden’s news agency, that temperatures there reached 80 degrees and some units caught fire, a figure that differs from the police number. In Belgium, Delhaize noticed temperature increases in its cooling systems on Monday, spokesperson Sarah De Meester said, and the company is investigating. Stephan Moelans, CEO of the refrigeration firm Sabcobel, which runs Delhaize’s systems, told the news agency Belga it was a cyberattack that switched the units’ evaporators to defrost mode. His office declined to comment to Reuters. Colruyt Group, which runs Spar stores in Belgium under a franchise system, said five shops had their fridge systems attacked, and Le Soir reported that dozens of Delhaize and Carrefour stores were affected. Ahold also reported a cybersecurity incident to Dutch police last month, after it detected suspicious activity in its infrastructure. Nothing in the reporting ties that report to Monday’s incident. Fridges and freezers at dozens of supermarkets in Belgium and Sweden overheated overnight in a suspected cyberattack, similar to the one that hit French stores three weeks ago. Delhaize calls it an "IT incident." Delhaize said about 40 of its Belgian stores were affected… pic.twitter.com/qzw6uDybWb — The Informant (@theinformant_x) November 2, 2026 In Sweden, John Billow, head of the national cybersecurity centre, told Reuters his team was working on several incidents involving refrigeration systems in grocery stores around the country. An ICA Kvantum store in Sjöbo said on Facebook that a cyberattack caused its problems, and an ICA store told its followers that its temperatures had been “hacked” overnight and set to 50 degrees. Fifty degrees is fine for a beach and poor for ice cream. That store later said it had opened. At ICA Baronen in Stockholm, a notice said all the freezers were broken because of a cyberattack. The sales manager said the attack came at 2 a.m. and staff noticed it at 5:30 a.m. ICA Hägerstensåsen in Stockholm was reportedly hit too. ICA said only a limited number of stores were affected and that it is helping them deal with the incident. However, press officer Gustaf Nilsson did not say how many stores were involved. Coop told Swedish news agencies Aftonbladet and TT that six stores in central Sweden had similar problems. Press manager Carlos Cancino said it was still unclear whether any food would need to be thrown away or whether the refrigeration units had simply stopped working or had switched to heating mode. He also did not rule out further incidents affecting other stores. An Estonian supermarket chain was also affected. Its refrigeration systems were reportedly set to 50°C, technology provider Kitman Coldtech told public broadcaster ERR. CEO Jann Mutso did not reveal the name of the supermarket chain, saying: “This is very recent. It happened this morning.” How did the attackers get in? In France, Olofsson says they obtained login details for the control systems, which were exposed directly to the internet. He says the attack targeted a product that controls the cooling systems and that the hack isn’t very complicated, so amateurs may have carried it out. Billow says Swedish authorities have noticed in recent weeks that quite a lot of exposed operational technology devices exist in Sweden, and they’ve been clear that these must be updated or patched. Refrigerators and heating systems, security cameras and alarm networks were once largely mechanical, and now they can be monitored and controlled remotely. That gives cybercriminals new openings. Authorities haven’t said who was behind last month’s incidents, and nobody has claimed responsibility. The Sweden Herald reported that the cause of the attacks on Swedish supermarkets remains unknown.

Taiwanese network-attached storage (NAS) appliance maker Synology warned customers to update their devices immediately due to a surge in C3RB3r ransomware attacks. The company urged users to enable automatic updates and upgrade the DiskStation Manager (DSM) software running on their NAS devices to the latest version to protect their data. "Synology has identified threat actors exploiting a vulnerability patched in December 2024 to target devices running outdated versions of DSM. These attacks aim to encrypt data and extort ransom," it said in a Thursday advisory. "Synology strongly urges all users running vulnerable versions to update DSM immediately to protect their systems. Synology also recommends enabling automatic updates to keep DSM up to date at all times." A Synology spokesperson was not immediately available when BleepingComputer reached out for more information on these C3RB3r ransomware attacks.
Hackers reportedly hit Ukraine ‘s and Russia ‘s emergency alert apps, sending fake nuclear and attack warnings and raising concerns over public safety. Ukraine and Russia both said on Sunday night that hackers had compromised their emergency alert apps and used them to send fake warnings about air raids and other attacks, including nuclear threats. The BBC reported the incident, but neither side’s claims have been independently confirmed. Shortly before 11 p.m. local time (9 p.m. GMT), Ukraine’s widely used Air Alarm app sent the highest-level air raid warnings across the country. Some people, including residents of Kyiv, also received alerts about possible radiation, chemical attacks and street fighting. A message posted on Telegram said the app had likely been targeted by a cyberattack, confirmed there was no radiation threat and urged people to remain calm. “Shortly before 23:00 local time (21:00 GMT), Ukraine’s widely usedair raid app sent red-level air raid warnings nation-wide, with additional warnings of radiation, chemical attacks, and street fighting sent to some residents in areas including Kyiv.” reports BBC. “The Air Alarm application has probably been subjected to hostile interference. There is no radiation threat! Stay calm and follow our updates on our channel.” an alert on Telegram read. The false alerts started at about 22:47 with a message that a radiation threat had been declared in Kyiv. At 22:48 came a message in Russian saying a nuclear alert would cover all of Ukraine and not to worry because “it’s Oreshnik flying”. Oreshnik is a Russian intermediate-range ballistic missile that can carry nuclear or conventional warheads, and Russia has the world’s biggest nuclear arsenal, with President Vladimir Putin repeatedly hinting he’s open to using every weapon available. Two more alerts arrived at 22:49. One, in Ukrainian, warned of a chemical attack on Kyiv and told people not to go outside, and the other said street fighting was taking place in the city. Red, orange and green messages reached phones, and at 23:53 users got all-clear messages, each declaring one of the Kyiv threats over. A Ukrainian intelligence body, which the BBC calls the Central Intelligence Agency, said there had been a failure in the app and urged people to use other sources of information. It added that the alerts triggered a radiation hazard signal on loudspeakers in the Lviv region, with no real threat. “The Air Alert app is supported by the Ministry of Digital Transformation of Ukraine, and informs users instantly about the beginning and end of defence alerts. The ministry said it temporarily disabled the app for maintenance after it had “apparently been compromised”. states BBC. “While the false alerts were quickly contained, cybersecurity experts suggested it was a new line in apparent Russian cyberattacks.” The temporary shutdown of the Air Alert app also carries significant risks, even if it lasts only a short time. During an outage, users may not receive timely warnings about incoming attacks, leaving them with less time to reach shelters or take protective measures. This is particularly dangerous in a country where missile and drone attacks can happen with little warning. The incident also highlights a difficult security trade-off: disabling a compromised alert system may prevent attackers from spreading false warnings, but it can temporarily remove a critical channel for delivering real emergency information. Any shutdown therefore needs reliable backup channels, such as sirens, official messaging services and other emergency communication systems. Regional leaders tried to calm people. Svitlana Onyshchuk, head of the Ivano-Frankivsk region, said everything was calm, even though the app had shown a red-level alert for her region from 22:50 to 23:57. Natalya Zabolotna, her counterpart in Vinnytsia, confirmed a cyberattack on the app and warned people not to click the link in the message, which could be phishing. Ukraine’s Centre for Countering Disinformation has advice for when the app isn’t working: turn on smartphone notifications, pay attention to sirens, and read only official sources. Oleksander Merezhko, chair of the foreign affairs committee in the Ukrainian parliament and a member of President Zelensky’s Servant of the People party, said the attack caused no panic. Ukrainians, especially in Kyiv, are used to practically non-stop alerts, he told the BBC, and the message in Russian aroused suspicion at once. The attackers picked a language that gave them away. A few hours later, Russia’s ministry of emergency situations said its own app had suffered “a massive cyberattack” that sent fake information to the public. Ukrainian outlet UNN reported that the hack sent fake nuclear threat alerts inside Russia, citing Atesh, a partisan Ukrainian group operating in Russian-held territory. A screenshot Atesh shared on Telegram, described as purported, claimed nuclear warheads mounted on Ukrainian P1-Sun attack drones had been launched at all regions of Russia, opened with a “risk of getting lively” warning and told residents to stock up on three weeks of food and hide. The alert also had profanities. Russia said it was still restoring the app but claimed the hack had not affected its wider alert system. It said people could still receive warnings through sirens, loudspeakers, text messages, TV and radio. The false alerts appeared minutes before a local ceasefire in Ukraine’s Kherson region ended on Sunday night. The truce had allowed civilians to leave Russian-occupied Oleshky. Although the fake warnings were quickly stopped, experts see the attack as a worrying escalation. “I think it’s the first time it’s happened to an official Ukrainian information app, but I suspect it won’t be the last,” Herbert Lin, a senior research scholar for cyber policy and security at Stanford University, told BBC World Service’s Newsday programme.

Ivanti released security updates to patch two more Connect Secure (ICS) remote access gateway flaws that have been chained in zero-day attacks since at least October 1. Threat actors exploited these two flaws (tracked as CVE-2026-111357 and CVE-2026-118527) alongside an authentication bypass vulnerability (CVE-2026-104935), which Ivanti patched last month to remove the main attack surface. CVE-2026-111357 is a high-severity privilege escalation flaw, and CVE-2026-118527 lets authenticated attackers upload files on an unpatched device. When it released patches for CVE-2026-104935 in October, Ivanti urged admins to upgrade as soon as possible since it was aware of "limited exploitation in the wild." "At the time of discovery of exploitation, Ivanti had a fix developed for CVE-2026-104935 which was already in QA for supported versions, and we made the decision to not delay getting a fix to customers that resolved the primary exploitation path when the LPE was discovered," Ivanti added in an advisory updated on Thursday.
Chainalysis suffered a cyberattack exposing customer names, emails and user IDs, while investigation data and passwords remain safe. Blockchain analytics firm Chainalysis says it was the target of a cybersecurity incident. A threat actor accessed its systems and internal tools and stole some non-sensitive customer data. “This month, Chainalysis detected an external actor using offensive agentic techniques to gain unauthorized access to Chainalysis systems and internal tools.” reads the statement published by the company, which also includes the full email sent to affected customers. Chainalysis says it discovered the attacker this month and described the methods used as offensive techniques involving AI agents. However, it did not explain how the attack was carried out. The company also warned that AI-powered attacks are becoming more common across the industry and said it is taking a company-wide approach to dealing with this growing threat. The data the attacker reached matters most. According to Chainalysis, attackers gained access to user IDs, full names, email addresses and organization role labels for users on the platform. The company is still working out which records belong to which customer and promises a detailed breakdown when it finishes. What the attacker didn’t reach is just as important. So far, Chainalysis has found no sign of access to investigation content such as graphs, notes or cases, or to transaction and query results. It also found no clear-text passwords, MFA secrets or user session tokens in the attacker’s hands. “Based on the evidence available to date, we have found no indication that these incidents resulted in the unauthorized access of investigation content (such as graphs, notes, or cases), transaction or query results, passwords in clear text, MFA secrets, or user session tokens.” continues the press release. Some non-sensitive customer data, such as user IDs, full names, email addresses, and organization role labels for users provisioned on our platform were accessed, including such information relating to your organization and users. We are in the process of determining the records for your organization that were accessed and will provide a detailed breakdown as soon as that analysis is complete.“ The company says it’s patching vulnerabilities and hardening its systems around the clock. It has hired outside cybersecurity experts and is using large language models to support a wider review that goes beyond the flaws the attacker used. It has already told all its customers and will keep them updated. Chainalysis advises customers to watch out for unexpected password reset requests or login approval prompts. The company also strongly recommends enabling two-factor authentication (2FA) for all organizations that have not already done so. Since the exposed data includes names and email addresses, attackers could use it to launch phishing campaigns. The company also clarified that the security incident has nothing to do with the recent theft of more than $6 billion from Binance.

The FBI has confirmed that North Korean state-sponsored hackers known as TraderTraitor were behind the $6.3 billion crypto-theft attack on Binance, making it the largest cryptocurrency heist on record. In a security alert published Saturday, the agency attributed the attack to TraderTraitor, a North Korean hacking group also tracked as Lazarus Group, Jade Sleet, and APT38, linked to numerous cryptocurrency thefts. "The Federal Bureau of Investigation (FBI) is releasing information advising the Democratic People's Republic of Korea (North Korea) was responsible for the theft of more than $6 billion USD in virtual assets from cryptocurrency exchange Binance, on or about October 29, 2026," the FBI said. This official attribution follows blockchain intelligence firms TRM Labs and Chainalysis, which had already linked the theft to TraderTraitor.
