Binance on Tuesday said the record-setting theft of $6.43 billion in assets from the world's largest cryptocurrency exchange was the culmination of a "sophisticated, multi-stage campaign" that involved the use of a tampered Homebrew installation and recruitment-themed social engineering attack targeting two of its engineers. "It was not a single isolated breach or a simple phishing incident," the company said . "The attackers combined a range of techniques, including social engineering by fake recruitment interviews, malicious software downloads, compromised internal AI tooling, endpoint compromise, and an advanced transaction-authorisation method." The starting point has been traced back to a supply chain attack targeting one of its engineers from the Wallet DevOps team (named "Engineer A"), who downloaded a trojanized Homebrew installer to install a popular artificial intelligence (AI) tool after searching for it on a search engine....

Barracuda has disclosed details of two vulnerabilities affecting its products that, if chained together, could allow an attacker to bypass authorization controls and gain root access to a susceptible device. The vulnerabilities, a pre-authentication authorization bypass vulnerability and a command injection vulnerability, have been assigned the CVE identifiers CVE-2026-116606 (CVSS score: 9.3) and CVE-2026-111560 (CVSS score: 8.6), respectively.

"If exploited in combination, these vulnerabilities could allow an attacker to bypass authorization co...

Google on Monday warned that threat actors are hijacking enterprise access to Large Language Models (LLMs) to fraudulently leverage expensive computing resources and AI services. The tactic is called LLMjacking , a form of resource hijacking adapted for the LLM era, where an attacker obtains an API key through phishing, source code leaks, misconfigured environments, or exposed client-side code to gain unauthorized access to an organization's LLM accounts, while the legitimate owner covers the consumption costs. Such attacks have a wide geographical footprint, with impacted entities located in North America, South America, and Asia Pacific across the financial services, retail, technology, and transportation sectors. "Unlike the gradual resource consumption associated with cryptojacking, LLMJacking can generate large spikes in fraudulent cloud charges in a matter of hours," Google Threat Intelligence Group and Mandiant said in a report shared with The Hacker News...

An attacker broke into the update system of the cPGuard security tool on November 2 and used it to send a malicious script to customers' Linux servers. The script installed a backdoor and collected password hashes and other sensitive files from servers that ran it, cPGuard maker OPSSHIELD said in an advisory . The attacker has since taken some of that data. cPGuard 5.88.25 and later versions remove the backdoor and the files the script left. Credentials the script copied may still work after the update, so any server that may have run the script also needs new passwords and keys. At 02:06 UTC, the attacker, who has not been identified, used compromised credentials to get into cPGuard's update system. The script went out in cPGuard versions 5.88.12 through 5.88.19. The attack was detected within 12 hours of those versions going out, according to OPSSHIELD. The company has cleared its infrastructure credentials and stopped the script from reaching more servers. It is sti...

Fixed kernels for a use-after-free vulnerability in the Linux kernel's IPv4 TCP code are now available for Red Hat Enterprise Linux 8, 9, and 10, while Ubuntu's fixes for its three newest long-term-support releases remain in its opt-in testing channel with no date for a regular update. The flaw, tracked as CVE-2026-98432 , can be reached by a remote, unauthenticated attacker and can lead to remote code execution,  Red Hat  and  Canonical  said. The Linux kernel's own CVE team rates the flaw 9.8 out of 10 on the CVSS scale. Red Hat, which initially rated it Moderate at 5.9, has raised its score to 9.8 and now calls it Critical. The bug has been present since Linux 4.4, and the upstream fix landed in October. What the Flaw Is When a server accepts an IPv4 TCP connection, the kernel passes IP options from the incoming request to the new socket without copying them. If the client retransmits its connection request while another processor still rea...

Your team is remediating more vulnerabilities than ever, yet your breach risk has barely changed. You’re spending too much time and effort on exposures attackers may never exploit, while higher-risk exposures sit, waiting in the queue. Gartner ® ’s report on exposure prioritization states that fewer than 10% of vulnerabilities are exploited, yet most are treated as urgent. The report also argues that CVSS scores alone do not predict actual exploitation or business impact. Gartner predicts that by 2028, organizations that prioritize exposures using threat intelligence , asset context , exploitability modeling , and security control validation will reduce breach likelihood by at least 70% compared to their peers relying primarily on CVSS-based vulnerability prioritization. Let’s break down how each element works, and how the Picus Platform puts all four into practice. Severity-based prioritization made sense. Then it didn't. Severity-driven prioritization was an entirely r...

A Russia-aligned threat actor known as Gorbag has been observed using simple information stealer malware in attacks targeting Ukrainian organizations. "Active since at least February 2025, the group has focused exclusively on Ukrainian targets, with a clear preference for law enforcement and justice entities, local administrations near the front line, and the defense sector," ESET researcher Damien Schaeffer said in a report shared with The Hacker News. The activity shares overlaps with a cluster tracked by the Computer Emergency Response Team of Ukraine (CERT-UA) under the moniker UAC-0226 and by Trend Micro as SHADOW-EARTH-066 . Gorbag is known to be active since at least February 2025. A key tool in the threat actor's malware arsenal is GIFTEDCROOK, a C/C++ stealer that facilitates the theft of sensitive data from web browsers like Google Chrome, Microsoft Edge, and Mozilla Firefox, such as cookies, browsing history, and authentication data. Earlier this Ju...

BTCPay Server, a self-hosted, open-source cryptocurrency payment processor, has urged users to install the latest version of its software in response to reports of Bitcoin and Litecoin being stolen from hot wallets on instances running older versions. "Our investigation found that these attacks targeted servers running BTCPay Server 2.4.1 (released on 23 July 2026) or earlier," BTCPay Server said . "The attackers used a different method to exploit the vulnerability fixed in 2.4.2, released on 7 August 2026." Users who are running versions 2.4.1 or earlier are recommended to move to a fresh server with a new wallet, even in scenarios where users have not noticed a theft. In the event of stolen funds or suspected unauthorized access, it's imperative that users consider the entire machine and all secrets stored on it as compromised and follow the same recovery procedures. It's currently unknown when the attackers behind the campaign first began exploi...

Synology is urging customers to update the DiskStation Manager (DSM) software powering its Network Attached Storage (NAS) devices following ransomware attacks. The Taiwanese vendor said it observed 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 statement released last week. While Synology did not disclose the exact security flaw that's being exploited in these attacks, the company linked to a November 2024 security advisory that listed three vulnerabilities - CVE-2024-10441 (CVSS score: 9.8) - An improper encoding or escaping of output vulnerability in the system plugin daemon of DSM that could lead to remote code execution via unspecified vectors. CVE-2024-50629 (CVSS score: 5.3) - An improper encoding or escaping of output vulnerability in the webapi component of DSM that could allow remote attackers to read limite...

Attackers remotely changed the settings on refrigeration controls at supermarkets in Belgium, Sweden, Estonia and other European countries overnight into Monday, November 2, warming fridges and freezers. No chain reported more than several dozen affected stores, and some had to throw away chilled and frozen food or take it off the shelf. Danfoss, a Danish maker of refrigeration controls,  said its products were involved , as they were three weeks earlier when  attackers hit hundreds of French supermarkets . No one had claimed the attacks by Monday night, and it was not known whether they were linked to the attack in France. Refrigeration controls are computers that run a store's fridges and freezers. They can be connected to the internet, allowing refrigeration contractors to monitor them and fix faults remotely. In Belgium, attackers switched cooling units into defrost mode, Stephan Moelans, chief executive of the refrigeration contractor Sabcobel,  told Belgi...

A maximum-severity security flaw impacting Siemens SIMATIC IoT2050 Advanced devices has come under active exploitation, VulnCheck has revealed . The vulnerability, tracked as CVE-2026-58115 (CVSS score: 10.0), is a case of missing authentication for a critical function that could be exploited by an unauthenticated remote attacker to run arbitrary code. "SIMATIC IoT2050 Advanced devices running Industrial OS with Node-RED installed contain a missing authentication vulnerability in the Node-RED HTTP interface that could allow an unauthenticated remote attacker to create malicious flows and execute arbitrary code on the underlying server with maximum privileges," Siemens said in an advisory released back in August 2026. The issue has been remediated in versions 4.3.4.1 or later. As mitigations, Siemens recommends that users uninstall Node-RED or harden the installation by following the steps below - Enabling HTTPS access Securing the editor and admin API via cre...

Threat actors are attempting to exploit an unpatched maximum-severity security vulnerability in the CryptoPayment Gateway WordPress plugin, according to findings from Defused Cyber. The vulnerability in question is CVE-2026-81648, which carries a CVSS score of 10.0. Successful exploitation of the flaw could permit unauthenticated users to delete arbitrary files on the server and extract sensitive data, including stored wallet credentials. "The CryptoPayment Gateway WordPress plugin from 1.2.1 to 1.2.2 does not apply an authorization check on one of its AJAX endpoints, allowing unauthenticated users to invoke administrative operations, including deleting arbitrary files on the server, overwriting the payment gateway configuration and recovering stored wallet credentials in cleartext," according to a description of the flaw on the NIST National Vulnerability Database (NVD). The vulnerability affects versions 1.2.1 through 1.2.2, which is the latest version. There are n...

Some attacks this week didn't need much of a trick. A fake support call, a trusted extension, a shared link, or a device with no password. Small things that people barely think about. Yet each was enough to cause serious trouble. Then there were the bigger messes. Billions stolen, hidden networks of hacked devices, poisoned software, and attackers finding new ways to turn normal tools against their users. Even the places meant to keep money and systems safe ended up with problems of their own. The strange part is how often the damage started somewhere nobody was looking. And that's before getting to the long list of fresh bugs, shady services, and scams making the rounds. Quite a bit to sort through. Here's what made the list. ⚡ Threat of the Week N. Korea Sets New Record with Binance $6.43B Crypto Theft — The U.S. Federal Bureau of Investigation (FBI) has officially attributed the theft of more than $6 billion in virtual assets from Binance to a North Korean hack...

A botnet of more than 1.3 million Android devices, mostly TV set-top boxes, lost control of its servers in late October in a takedown led by Google. Google says  it is highly confident that device maker Videostrong intentionally put a backdoor in the boxes and sold access to criminals. They used the boxes for ad fraud and to pass other people's internet traffic through owners' home connections. The backdoor is still on the boxes, and owners cannot remove it themselves. Videostrong, based in Shenzhen, China, makes Android TV boxes and other devices under its own name and for other brands. The backdoor, called x.cpe, was built into many device models and brands over several years. Google does not believe a rogue insider or a mistake was to blame. Google used legal action to take down the domains and servers that controlled the botnet. It also took down the control domains of more than a dozen malware families loaded through the backdoor. Japan's National Police Agenc...

Cybersecurity researchers have disclosed details of a cyber espionage campaign targeting Israel and the Kurdistan Region of Iraq by an Iran state-aligned threat actor between August and October 2026. According to a report published by Dream Research Labs, the campaign has led to the compromise of a high-profile individual in Israel, along with additional compromises affecting a government cloud environment in the Kurdistan Region. The activity has been attributed to a threat actor known as DarkBlinders , an Iran-nexus group assessed to be active since at least September 2024 and linked to attacks aimed at aviation infrastructure and telecommunications in the U.A.E. and Iraq. It exhibits no technical overlap with other known hacking groups. Attacks mounted by the group are known to rely on spear-phishing as an initial access pathway to lure recipients into opening trojanized utilities or clicking on attacker-controlled websites that host similar tools as direct downloads. Prev...

Two critical flaws in Langflow could let a remote attacker with no account bypass authentication or run arbitrary code,  IBM said last week . Langflow is an open-source tool for building AI agents and workflows, and its vulnerability reports go to IBM. Every release from 1.0.0 through 1.12.8 has the flaws, and the only fix is version 1.13.0. Neither flaw is in CISA's Known Exploited Vulnerabilities catalog, as of the catalog's October 30 update. Six other Langflow flaws are listed there, most recently CVE-2026-9198, which was added in August . The four Langflow flaws in IBM's bulletin, first published on October 28 and updated the next day, are:
