Meta Platforms is said to have fired or disciplined over two dozen employees and contractors over the past year for allegedly compromising and taking over user accounts, The Wall Street Journal reported Thursday. Some of these cases involved bribery, the publication said, citing sources and documents. Included among those fired were contractors who worked as security guards at the social media firm's facilities and were given access to an internal tool that allowed employees to help "users they know" gain access to accounts after forgetting their passwords, or had their accounts locked out. The system, called "Oops" and short for Online Operations, is off limits to a vast majority of the platform's users, leading to the rise of a "cottage industry of intermediaries" who charge users thousands of dollars and reach out to insiders who are willing to reset the accounts. "You really have to have someone on the inside who will actually do it...

The LodaRAT malware has resurfaced with new variants that are being deployed in conjunction with other sophisticated malware, such as RedLine Stealer and Neshta. "The ease of access to its source code makes LodaRAT an attractive tool for any threat actor who is interested in its capabilities," Cisco Talos researcher Chris Neal  said  in a write-up published Thursday. Aside from being dropped alongside other malware families, LodaRAT has also been observed being delivered through a previously unknown variant of another commodity trojan called  Venom RAT , which has been codenamed S500. An AutoIT-based malware, LodaRAT (aka  Nymeria ) is attributed to a group called Kasablanca and is capable of harvesting sensitive information from compromised machines. In February 2021, an  Android version  of the malware sprang forth as a way for the threat actors to expand their attack surface. Then in September 2022, Zscaler ThreatLabz uncovered a new delivery mecha...

Threat hunting is the process of looking for malicious activity and its artifacts in a computer system or network. Threat hunting is carried out intermittently in an environment regardless of whether or not threats have been discovered by automated security solutions. Some threat actors may stay dormant in an organization's infrastructure, extending their access while waiting for the right opportunity to exploit discovered weaknesses. Therefore it is important to perform threat hunting to identify malicious actors in an environment and stop them before they achieve their ultimate goal.  To effectively perform threat hunting, the threat hunter must have a systematic approach to emulating possible adversary behavior. This adversarial behavior determines what artifacts can be searched for that indicate ongoing or past malicious activity. MITRE ATT&CK Over the years, the security community has observed that threat actors have commonly used many tactics, techniques, and procedu...

The threat actors behind the Hive ransomware-as-a-service (RaaS) scheme have launched attacks against over 1,300 companies across the world, netting the gang $100 million in illicit payments as of November 2022. "Hive ransomware has targeted a wide range of businesses and critical infrastructure sectors, including government facilities, communications, critical manufacturing, information technology, and — especially — Healthcare and Public Health (HPH)," U.S. cybersecurity and intelligence authorities  said  in an alert. Active since June 2021, Hive's RaaS operation involves a mix of developers, who create and manage the malware, and affiliates, who are responsible for conducting the attacks on target networks by often purchasing initial access from initial access brokers (IABs). In most cases, gaining a foothold involves the exploitation of  ProxyShell flaws  in Microsoft Exchange Server, followed by taking steps to terminate processes associated with antivirus...

An ongoing supply chain attack has been leveraging malicious Python packages to distribute malware called W4SP Stealer, with over hundreds of victims ensnared to date. "The threat actor is still active and is releasing more malicious packages," Checkmarx researcher Jossef Harush  said  in a technical write-up, calling the adversary  WASP . "The attack seems related to cybercrime as the attacker claims that these tools are undetectable to increase sales." The findings from Checkmarx build on recent reports from  Phylum  and  Check Point , which flagged 30 different modules published on the Python Package Index (PyPI) that were designed to propagate malicious code under the guise of benign-looking packages. The attack is just the latest threat to target the software supply chain. What makes it notable is the use of steganography to extract a  polymorphic malware  payload hidden within an image file hosted on Imgur. The installation of the pac...

A China-based financially motivated group is leveraging the trust associated with popular international brands to orchestrate a large-scale phishing campaign dating back as far as 2019. The threat actor, dubbed Fangxiao by Cyjax, is said to have registered over  42,000 imposter domains , with initial activity observed in 2017. "It targets businesses in multiple verticals including retail, banking, travel, and energy," researchers Emily Dennison and Alana Witten  said . "Promised financial or physical incentives are used to trick victims into further spreading the campaign via WhatsApp." Users clicking on a link sent through the messaging app are directed to an actor-controlled site, which, in turn, sends them to a landing domain impersonating a well-known brand, from where the victims are once again taken to sites distributing fraudulent apps and bogus rewards. These sites prompt the visitors to complete a survey to claim cash prizes, in exchange for which the...

A Ukrainian national who has been wanted by the U.S for over a decade has been arrested by Swiss authorities for his role in a notorious cybercriminal ring that stole millions of dollars from victims' bank accounts using malware called Zeus . Vyacheslav Igorevich Penchukov, who went by online pseu­do­nyms "tank" and "father," is alleged to have been involved in the day-to-day operations of the group. He was apprehended in Geneva on October 23, 2022, and is pending extradition to the U.S. Details of the arrest were  first reported  by independent security journalist Brian Krebs. Penchukov, along with Ivan Viktorovich Klepikov (aka "petrovich" and "nowhere") and Alexey Dmitrievich Bron (aka "thehead"), was originally charged in the District of Nebraska in August 2012. According to court documents released by the U.S. Department of Justice (DoJ) in 2014, Penchukov and eight other members of the cybercriminal group  infected  ...
