Microsoft on Friday warned of active attacks exploiting unpatched Exchange Servers carried out by multiple threat actors, as the hacking campaign is believed to have infected tens of thousands of businesses, government entities in the U.S., Asia, and Europe. The company  said  "it continues to see increased use of these vulnerabilities in attacks targeting unpatched systems by multiple malicious actors beyond HAFNIUM," signaling an escalation that the breaches are no longer "limited and targeted" as was previously deemed. According to independent cybersecurity journalist  Brian Krebs , at least 30,000 entities across the U.S. — mainly small businesses, towns, cities, and local governments — have been compromised by an "unusually aggressive" Chinese group that has set its sights on stealing emails from victim organizations by exploiting previously undisclosed flaws in Exchange Server. Victims are also being reported from outside the U.S., with email s...

Cybersecurity researchers on Thursday disclosed two distinct design and implementation flaws in Apple's crowdsourced Bluetooth location tracking system that can lead to a location correlation attack and unauthorized access to the location history of the past seven days, thereby deanonymizing users. The  findings  are a consequence of an exhaustive review undertaken by the Open Wireless Link (OWL) project, a team of researchers from the Secure Mobile Networking Lab at the Technical University of Darmstadt, Germany, who have historically taken apart Apple's wireless ecosystem with the goal of identifying security and privacy issues. In response to the disclosures on July 2, 2020, Apple is said to have partially addressed the issues, stated the researchers, who used their own data for the study citing privacy implications of the analysis. How Find My Works? Apple devices come with a feature called  Find My  that makes it easy for users to locate other Apple devices...

AI agents promise to automate everything from financial reconciliations to incident response. Yet every time an AI agent spins up a workflow, it has to authenticate somewhere; often with a high-privilege API key, OAuth token, or service account that defenders can't easily see. These "invisible" non-human identities (NHIs) now outnumber human accounts in most cloud environments, and they have become one of the ripest targets for attackers. Astrix's Field CTO Jonathan Sander put it bluntly in a recent Hacker News webinar : "One dangerous habit we've had for a long time is trusting application logic to act as the guardrails. That doesn't work when your AI agent is powered by LLMs that don't stop and think when they're about to do something wrong. They just do it." Why AI Agents Redefine Identity Risk Autonomy changes everything: An AI agent can chain multiple API calls and modify data without a human in the loop. If the underlying credential is exposed or overprivileged, each addit...

In what's a case of hackers getting hacked, a prominent underground online criminal forum by the name of Maza has been compromised by unknown attackers, making it the fourth forum to have been breached since the start of the year. The intrusion is said to have occurred on March 3, with information about the forum members — including usernames, email addresses, and hashed passwords — publicly disclosed on a breach notification page put up by the attackers, stating "Your data has been leaked" and "This forum has been hacked." "The announcement was accompanied by a PDF file allegedly containing a portion of forum user data. The file comprised more than 3,000 rows, containing usernames, partially obfuscated password hashes, email addresses and other contact details," cybersecurity firm Intel 471  said . Originally called Mazafaka, Maza is an elite, invite-only Russian-language cybercrime forum known to be operational as early as 2003, acting as an exc...

FireEye and Microsoft on Thursday said they discovered three more malware strains in connection with the SolarWinds supply-chain attack, including a "sophisticated second-stage backdoor," as the investigation into the  sprawling espionage campaign  continues to yield fresh clues about the threat actor's tactics and techniques.  Dubbed GoldMax (aka SUNSHUTTLE), GoldFinder, and Sibot, the new set of malware adds to a growing list of malicious tools such as  Sunspot ,  Sunburst  (or Solorigate),  Teardrop , and  Raindrop  that were stealthily delivered to enterprise networks by  alleged Russian operatives . "These tools are new pieces of malware that are unique to this actor," Microsoft  said . "They are tailor-made for specific networks and are assessed to be introduced after the actor has gained access through compromised credentials or the SolarWinds binary and after moving laterally with Teardrop and other hands-on-keyboard act...

Signaling a major shift to its ads-driven business model, Google on Wednesday unequivocally stated it would not build alternate identifiers or tools to track users across multiple websites once it begins phasing out third-party tracking cookies from its Chrome browser by early 2022. "Instead, our web products will be powered by privacy-preserving APIs which prevent individual tracking while still delivering results for advertisers and publishers,"  said  David Temkin, Google's director of product management for ads privacy and trust. "Advances in aggregation, anonymization, on-device processing and other privacy-preserving technologies offer a clear path to replacing individual identifiers." The changes, which could potentially reshape the advertising landscape, are expected only to cover websites visited via Chrome and do not extend to mobile apps. At the same time, Google acknowledged that other companies might find alternative ways to track individual us...

Enterprise cloud security firm Qualys has become the latest victim to join a long list of entities to have suffered a data breach after zero-day vulnerabilities in its Accellion File Transfer Appliance (FTA) server were exploited to steal sensitive business documents. As proof of access to the data, the cybercriminals behind the recent hacks targeting Accellion FTA servers have shared screenshots of files belonging to the company's customers on a publicly accessible data leak website operated by the CLOP ransomware gang. Confirming the incident, Qualys Chief Information Security Officer Ben Carr  said  a detailed probe "identified unauthorized access to files hosted on the Accellion FTA server" located in a DMZ (aka  demilitarized zone ) environment that's segregated from the rest of the internal network. "Based on this investigation, we immediately notified the limited number of customers impacted by this unauthorized access," Carr added. "The in...

Following Microsoft's release of out-of-band patches to address multiple zero-day flaws in on-premises versions of Microsoft Exchange Server, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  issued  an emergency directive warning of " active exploitation " of the vulnerabilities. The alert comes on the heels of Microsoft's  disclosure  that China-based hackers were exploiting unknown software bugs in Exchange server to steal sensitive data from select targets, marking the second time in four months that the U.S. has scrambled to address a widespread hacking campaign believed to be the work of foreign threat actors. While the company mainly attributed the campaign to a threat group called HAFNIUM, Slovakian cybersecurity firm ESET  said  it found evidence of CVE-2021-26855 being actively exploited in the wild by several cyber espionage groups, including LuckyMouse, Tick, and Calypso targeting servers located in the U.S., Europe, Asi...

Cybercriminals are now deploying remote access Trojans (RATs) under the guise of seemingly innocuous images hosted on infected websites, once again highlighting how threat actors quickly change tactics when their attack methods are discovered and exposed publicly. New research released by Cisco Talos reveals an active malware campaign targeting organizations in South Asia that utilize malicious Microsoft Office documents forged with macros to spread a RAT that goes by the name of  ObliqueRAT . First documented in  February 2020 , the malware has been linked to a threat actor tracked as  Transparent Tribe  (aka Operation C-Major, Mythic Leopard, or APT36), a highly prolific group allegedly of Pakistani origin known for its attacks against human rights activists in the country as well as military and government personnel in India. While the ObliqueRAT modus operandi previously overlapped with another Transparent Tribe campaign in December 2019 to disseminate Crims...
