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....

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...

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...

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...

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...
