A group of academics from the New Jersey Institute of Technology (NJIT) has warned of a novel technique that could be used to defeat  anonymity protections  and identify a unique website visitor. "An attacker who has complete or partial control over a website can learn whether a specific target (i.e., a unique individual) is browsing the website," the researchers  said . "The attacker knows this target only through a public identifier, such as an email address or a Twitter handle." The cache-based targeted  de-anonymization attack  is a  cross-site leak  that involves the adversary leveraging a service such as Google Drive, Dropbox, or YouTube to privately share a resource (e.g., image, video, or a YouTube playlist) with the target, followed by embedding the shared resource into the attack website. This can be achieved by, say, privately sharing the resource with the target using the victim's email address or the appropriate username associated wit...

An emerging threat cluster originating from North Korea has been linked to developing and using ransomware in cyberattacks targeting small businesses since September 2021. The group, which calls itself H0lyGh0st after the ransomware payload of the same name, is being tracked by the Microsoft Threat Intelligence Center under the moniker DEV-0530, a designation assigned for unknown, emerging, or a developing group of threat activity. Targeted entities primarily include small-to-midsize businesses such as manufacturing organizations, banks, schools, and event and meeting planning companies. "Along with their H0lyGh0st payload, DEV-0530 maintains an .onion site that the group uses to interact with their victims," the researchers  said  in a Thursday analysis. "The group's standard methodology is to encrypt all files on the target device and use the file extension .h0lyenc, send the victim a sample of the files as proof, and then demand payment in Bitcoin in exchange...

The botnet behind the largest HTTPS distributed denial-of-service (DDoS) attack in June 2022 has been linked to a spate of attacks aimed at nearly 1,000 Cloudflare customers. Calling the powerful botnet  Mantis , the web performance and security company attributed it to more than 3,000 HTTP DDoS attacks against its users. The most attacked industry verticals include internet and telecom, media, gaming, finance, business, and shopping, of which over 20% of the attacks targeted U.S.-based companies, followed by Russia, Turkey, France, Poland, Ukraine, the U.K., Germany, the Netherlands, and Canada. Last month, the company said it  mitigated  a record-breaking DDoS attack aimed at an unnamed customer website using its Free plan that peaked at 26 million requests per second (RPS), with each node generating approximately 5,200 RPS. The tsunami of junk traffic lasted less than 30 seconds and generated more than 212 million HTTPS requests from more than 1,500 networks in 1...

Joshua Schulte, a former programmer with the U.S. Central Intelligence Agency (CIA), has been found guilty of leaking a trove of classified hacking tools and exploits dubbed  Vault 7  to WikiLeaks. The 33-year-old engineer had been  charged  in June 2018 with unauthorized disclosure of classified information and theft of classified material. Schulte also  faces  a separate trial on charges related to possession of child pornographic photos and videos, for which he was arrested on August 24, 2017. U.S. Attorney Damian Williams  said  in a statement that Schulte was convicted for "one of the most brazen and damaging acts of espionage in American history," adding his actions had a "devastating effect on our intelligence community by providing critical intelligence to those who wish to do us harm." WikiLeaks would go on to release the documents on March 7, 2017,  calling  it the "largest ever publication of confidential documents on the...

Nation-state hacking groups aligned with China, Iran, North Korea, and Turkey have been targeting journalists to conduct espionage and spread malware as part of a series of campaigns since early 2021. "Most commonly, phishing attacks targeting journalists are used for espionage or to gain key insights into the inner workings of another government, company, or other area of state-designated import," Proofpoint  said  in a report shared with The Hacker News. The ultimate goal of the "sustained" intrusions, the enterprise security firm said, is to gain a competitive intelligence edge or spread disinformation and propaganda. Proofpoint said it identified two Chinese hacking groups, TA412 (aka  Zirconium  or Judgment Panda) and  TA459 , targeting media personnel with malicious emails containing web beacons and weaponized documents respectively that were used to amass information about the recipients' network environments and drop  Chinoxy  malware. I...

Although there is a greater awareness of cybersecurity threats than ever before, it is becoming increasingly difficult for IT departments to get their security budgets approved. Security budgets seem to shrink each year and IT pros are constantly being asked to do more with less. Even so, the situation may not be hopeless. There are some things that IT pros can do to improve the chances of getting their security budgets approved.  Presenting the Problem in a Compelling Way If you want to get your proposed security budget approved, you will need to present security problems in a compelling way. While those who are in charge of the organization's finances are likely aware of the need for good security, they have probably also seen enough examples of "a security solution in search of a problem" to make them skeptical of security spending requests. If you want to persuade those who control the money, then you will need to convince them of three things: You are trying to ...

Microsoft on Wednesday shed light on a now patched security vulnerability affecting Apple's operating systems that, if successfully exploited, could allow attackers to escalate device privileges and deploy malware. "An attacker could take advantage of this sandbox escape vulnerability to gain elevated privileges on the affected device or execute malicious commands like installing additional payloads," Jonathan Bar Or of the Microsoft 365 Defender Research Team  said  in a write-up. Tracked as  CVE-2022-26706  (CVSS score: 5.5), the security vulnerability impacts iOS, iPadOS, macOS, tvOS, and watchOS and was fixed by Apple in May 2022. Calling it an access issue affecting the LaunchServices (launchd) component, the iPhone maker noted that "A sandboxed process may be able to circumvent sandbox restrictions," adding it mitigated the issue with additional restrictions. While Apple's  App Sandbox  is designed to tightly regulate a third-party app's acce...

The advanced persistent threat (APT) group known as Transparent Tribe has been attributed to a new ongoing phishing campaign targeting students at various educational institutions in India at least since December 2021. "This new campaign also suggests that the APT is actively expanding its network of victims to include civilian users," Cisco Talos  said  in a report shared with The Hacker News. Also tracked under the monikers APT36, Operation C-Major, PROJECTM, Mythic Leopard, the Transparent Tribe actor is  suspected  to be of Pakistani origin and is known to strike government entities and think tanks in India and Afghanistan with custom malware such as CrimsonRAT, ObliqueRAT, and CapraRAT. But the targeting of educational institutions and students, first  observed  by India-based K7 Labs in May 2022, indicates a deviation from the adversary's typical focus. "The latest targeting of the educational sector may align with the strategic goals of espion...

Security researchers have uncovered yet another vulnerability affecting numerous older AMD and Intel microprocessors that could bypass current defenses and result in Spectre-based speculative-execution attacks. Dubbed  Retbleed  by ETH Zurich researchers Johannes Wikner and Kaveh Razavi, the issue is tracked as CVE-2022-29900 (AMD) and CVE-2022-29901 (Intel), with the chipmakers  releasing   software   mitigations  as part of a coordinated disclosure process. Retbleed is also the latest addition to a class of  Spectre attacks  known as Spectre-BTI (CVE-2017-5715 or Spectre-V2), which exploit the side effects of an optimization technique called  speculative execution  by means of a timing side channel to trick a program into accessing arbitrary locations in its memory space and leak private information. Speculative execution attempts to fill the instruction pipeline of a program by predicting which instruction will be executed next i...

The U.S. Federal Trade Commission (FTC) warned this week that it will crack down on tech companies' illegal use and sharing of highly sensitive data and false claims about data anonymization. "While many consumers may happily offer their location data in exchange for real-time crowd-sourced advice on the fastest route home, they likely think differently about having their thinly-disguised online identity associated with the frequency of their visits to a therapist or cancer doctor," FTC's Kristin Cohen  said . The sensitive nature of information about users' health and their precise whereabouts has prompted the agency to caution against opaque practices in the "shadowy ad tech and  data broker ecosystem ," with consumers having little to no knowledge of how their personal data is harvested, used, and processed. This lack of awareness is compounded by the fact that mobile apps embed privacy-invasive software development kits (SDKs) that surreptitious...
