York University's Behavior-Centric Cybersecurity Center (BCCC) is working with the network monitoring company cPacket to combat a significant cybercrime threat, Distributed Denial-of-Service (DDoS) attacks. Institutions sometimes detect DDoS attacks too late to stop them. Due to the need for real-time detection to combat this threat, York University's BCCC and the cPacket company collaborated to develop a solution to help cybersecurity researchers study and respond to DDoS attacks more effectively.

The National Security Agency (NSA), Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), Environmental Protection Agency (EPA), Department of Energy (DOE), US Department of Agriculture (USDA), Multi-State Information Sharing and Analysis Center (MS-ISAC), and more have released a Fact Sheet urging critical infrastructure organizations to mitigate pro-Russia hacktivist cyber activity against Operational Technology (OT) devices.

The US Securities and Exchange Commission's (SEC) new Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure ruling took effect last fall. Public companies must disclose whether their boards of directors have cybersecurity experts.

Attacks on GPS signals and wider satellite navigation systems, known as GNSS, have increased. Attackers can jam signals, forcing them offline, or spoof signals to make aircraft and ships appear in false locations on maps. Governments and telecommunications organizations, along with airline safety experts, are now warning of disruptions and potential major disasters stemming from such attacks. Attacks against GPS, and the wider GNSS category take two forms.

Phishing campaigns involving Microsoft Azure and Cloudflare lures are now spreading "Latrodectus" malware. Latrodectus, also known as "Unidentified 111" and "IceNova," is a Windows malware downloader that serves as a backdoor, downloading EXE and DLL payloads or executing commands. Researchers have linked the malware to the developers of the IcedID modular malware loader. The newer malware is increasingly being used in phishing campaigns and contact form spam for initial access to corporate networks.

According to a study published by the University of Toronto's Citizen Lab, 1 billion smartphone users are exposed due to digital Chinese-language keyboards that are vulnerable to spying and eavesdropping. The discovered flaws provide a new cyberattack exploit, regardless of whether the device's keyboard is Chinese, English, or another language. Tencent's proprietary Chinese keyboard system was studied by the Citizen Lab last year.
