The Security Service of Ukraine (SSU) said it, together with the U.S. Federal Bureau of Investigation (FBI), uncovered a long-running campaign orchestrated by Russian intelligence services to break into the messaging accounts of government officials, military personnel, politicians, and activists in Ukraine, Europe, and the U.S. The systematic cyber attacks aimed at stealing sensitive information from the victims, the agency added. "The goal of these 'hacks' is to gain access to sensitive military, political, and economic information exchanged by users, as well as to steal their personal data," the agency warned in a post shared on Telegram. To pull off the operation, the attackers send SMS messages that masquerade as the messaging platform's support bot and urge users to disclose their account credentials.  The SSU noted that these attacks include not only organizations, officials or public figures, but also personal accounts belonging to Ukrainian nati...

OpenAI on Friday released three versions of GPT-5.6 , called Sol, Terra, and Luna , as a limited preview to a small number of companies as part of an ongoing engagement with the U.S. government. While Sol is the latest flagship model and the most powerful, Terra strikes a balance between efficiency and power, and Luna is fine-tuned for speed and affordability. "GPT‑5.6 Sol launches with our most robust safety stack to date. We strengthened protections for higher-risk activity, sensitive cyber requests, and repeated misuse, and spent multiple weeks finding weaknesses, pressure-testing our system, and hardening it against real-world attacks," OpenAI said . The model has also been touted as the "most capable model yet" for cybersecurity, making it much more suitable for vulnerability research and exploitation. On ExploitBench , GPT‑5.6 Sol is competitive with Anthropic Mythos Preview using only about one-third of the output tokens, OpenAI noted. The goal, ...

The FBI and CISA have updated  their March warning  about Russian intelligence phishing Signal accounts, and the operators have added a step: they now coax targets into handing over their Signal Backup Recovery Key. Hand it over once, and the attacker can restore the account's backup, read the private and group message history, and take over the account. Worse, the key keeps working. Make a new account on the same phone number, and the old key can still be used against it, the advisory warns. The fix is blunt: generate a new key in Settings, which kills the old one for future backup downloads, and accept that anything the attacker already pulled is gone. The updated advisory, PSA I-062626-PSA , adds two public tracking names the March notice lacked: UNC5792 and UNC4221. The FBI ties the activity to multiple Russian Intelligence Services (RIS) groups, including FSB officers embedded with the FSB Border Guards and others working for the Russian military services. The ca...

A newly discovered cyber attack campaign has been observed delivering a previously undocumented malware family called SharkLoader that acts as a loader for deploying Cobalt Strike Beacon on compromised hosts. Kaspersky, which is tracking the activity under the moniker StrikeShark , said the campaign has targeted a diplomatic organization in Indonesia, government organizations in Taiwan, software development companies across multiple countries, and entities associated with other sectors located in Hong Kong, Lebanon, Syria, Colombia, North Macedonia, Nepal, and Serbia.  "The observed victimology suggests a campaign with broad geographic reach and a diverse target set rather than a narrow focus on a specific industry or region," the Russian cybersecurity vendor said . The campaign does not exhibit direct links to any known threat actor or group, although the operators have utilized several open-source post-compromise tools like FScan and Pillager , which are commonly p...

A Chinese-speaking advanced persistent threat (APT) actor has been linked to a new custom backdoor called TinyRCT as part of cyber attacks aimed at government entities and critical infrastructure in Southeast Asia. The activity, particularly aimed at state-owned enterprises in the energy and government sectors, has been attributed to a threat actor called CL-STA-1062 , which Palo Alto Networks Unit 42 said shares overlaps with UAT-7237 , a hacking group that was first flagged by Cisco Talos in August 2025 in relation to a campaign directed against web infrastructure entities in Taiwan. Unit 42 said it also observed CL-STA-1062 campaigns in prior operations targeting strategic sectors in East Asia since March 2022, suggesting a broader but sustained focus in the region. "From a technical standpoint, the attackers behind CL-STA-1062 rely on a hybrid toolkit," Unit 42 said in a technical report. "While they frequently use common open-source tools such as SoftEther ...

A flaw in the Linux kernel's traffic-control subsystem can let a local unprivileged user gain root on affected systems. CVE-2026-46331 , nicknamed " pedit COW ," is an out-of-bounds write in the packet-editing action (act_pedit) that corrupts shared page-cache memory. A  public, working exploit  appeared within a day of the CVE assignment on June 16. Red Hat  rates the flaw as important . The exploit never touches the file on disk. It poisons the cached copy of a setuid root binary (/bin/su) in memory, injects a small payload, and runs that altered image as root. File-integrity checks come back clean while a root shell is already open. The exploit needs two things: act_pedit being loadable and unprivileged user namespaces being open, giving the attacker a namespace-local networking capability (CAP_NET_ADMIN) needed to trigger the bug. On the tested RHEL and Debian targets, both conditions were present. How the Bug Works Linux's tc traffic-...
