In a coordinated effort labeled Operation Cronos, law enforcement agencies across multiple countries arrested two LockBit ransomware operators, seized over 200 crypto wallets, and created a decryption tool to aid victims. The operation, spearheaded by the U.K National Crime Agency and supported by Europol and Eurojust, resulted in the takedown of 34 servers worldwide. Additionally, almost 1,000 decryption keys were retrieved, enabling the development of a LockBit 3.0 decryption tool. It also resulted in the shutdown of over 14,000 accounts on third-party services such as Mega, Tutanota, and Protonmail.
Meta Platforms revealed taking actions against at least eight spyware operators based in Italy, Spain, and the UAE, as part of its Adversarial Threat Report. These firms, including Cy4Gate/ELT Group and RCS Labs, were spotted deploying spyware across iOS, Android, and Windows devices. These operations involved scraping, social engineering, and phishing across multiple platforms. The firm has removed over 2,000 accounts linked to coordinated inauthentic behavior from China, Myanmar, and Ukraine.
Google is open-sourcing Magika, an AI-powered tool for identifying file types to enhance digital security.

Google emphasizes the benefits of deploying AI at scale to strengthen digital security and shift the cybersecurity balance from attackers to defenders.
The Biden administration issued an executive order to strengthen cybersecurity at U.S. port facilities and invest over $20 billion in port infrastructure to bring back manufacturing capacity. The U.S. Coast Guard will have the authority to respond to cyber activity in the marine transportation system, and minimum standards for port cybersecurity will be established to address the growing concerns about the stability of the global supply chain.
Amidst growing concerns over data security, American Vision Partners initiated notifications to approximately 2.4 million patients following a security breach dating back to November 2023. Meanwhile, in the cryptocurrency realm, FixedFloat grapples with a significant data breach resulting in the loss of roughly $26 million worth of BTC and ETH. Simultaneously, the ALPHV ransomware group's claim of responsibility for breaches at Prudential Financial and loanDepot underscores the ongoing threats faced by major corporations.
American Vision Partners notified around 2.4 million patients of a November 2023 security incident. The breach involved unauthorized access to parts of the network, and compromised personal information, including names, contact details, birthdates, medical records, and in some cases, SSNs and insurance information. Affected individuals have been advised to monitor their credit reports and account statements.
FixedFloat, a decentralized cryptocurrency exchange, fell victim to a significant data breach resulting in the theft of approximately $26 million worth of BTC and ETH. The exchange, known for its non-KYC model, experienced frozen transactions and missing funds, prompting an investigation into the security incident. While initially attributed to technical issues, the attack has been confirmed as an external breach, refuting rumors of insider involvement.
Zenlayer, a global network services provider, exposed an internal database with 384 million records, including customer contact information, due to a flaw reported by a security researcher. The exposed database contained server logs, VPN records, and various IP addresses, potentially exposing the internal network architecture and posing a risk of further cyberattacks.
Winter Vivern, the threat group associated with Belarus and Russia, has been discovered targeting European government and military mail servers. The attack chains exploit Roundcube vulnerabilities, deploying JavaScript payloads to extract user credentials sent to a C2 server. The campaign has impacted over 80 organizations, mainly in Georgia, Poland, and Ukraine, to collect intelligence on European political and military activities.
The ALPHV/Blackcat ransomware gang claimed responsibility for recently breaching Fortune 500 companies Prudential Financial and loanDepot. While loanDepot confirmed a data breach affecting 16.6 million individuals, Prudential is still assessing the full scope of the incident. ALPHV revealed plans to sell loanDepot's stolen data and release Prudential's data for free.
Hackers operating under the aliases IntelBroker and Sanggiero claim to have breached staffing giant Robert Half International once more, offering a trove of stolen data for $20,000 in Monero. The data purportedly includes confidential records, employee documents, customer information, and service configuration settings. The full extent of the breach and the number of affected individuals remain unclear.
A recent investigation uncovered a vast network of fraudulent ads promoting utility scams. In this attack campaign, many Pakistani adversaries were seen employing extortion tactics to coerce victims into making immediate payments or divulging sensitive information to restore their connection. Sophisticated tactics like fraudulent ads shown in Google searches are at the core of this campaign.
The Cactus ransomware group took responsibility for crippling Schneider Electric's network and stealing 1.5TB of data. As proof of its claims, the group leaked 25MB of allegedly stolen data on its dark web leak site, including snapshots of American citizens' passports and NDA document scans. The breach occurred on January 17th, targeting Schneider Electric's Sustainability Business division.
Internal documents leaked from iSoon, a Chinese hacking contractor, offered a peek into a workforce engaging in government-led hacking operations, mainly for China's Ministry of Public Security. The leak (including spreadsheets, chat logs, and marketing materials) posted on GitHub exposed low wages and shared hacking tools, such as the Winnti backdoor and PlugX RAT. Possibly, criminals also targeted NATO countries.
Operation at Germany-based PSI Software suffered a ransomware attack that impacted internal systems, leading to external connections and systems being shut down. While the attack vector is being determined, no customer systems appear compromised. Hunters International, a RaaS operation, claimed responsibility for the attack, allegedly stealing over 36,000 files totaling 88GB.
Prince George’s County Public Schools, a Washington, D.C. suburban school district, disclosed that the ransomware attack from last year also compromised the personal information of nearly 100,000 individuals.
