Cybersecurity Brief – 2025-08-07
Major Incidents or Breaches
- Google has suffered a data breach as part of an ongoing campaign targeting Salesforce CRM data, attributed to the ShinyHunters extortion group. Several major companies have been impacted by this wave of attacks.
- DaVita has notified over 1 million individuals that their personal and health information was stolen in a ransomware attack.
- WhatsApp has taken down 6.8 million accounts linked to criminal scam centres, with Meta attributing the activity to a scam centre in Cambodia.
- A hacker, Chukwuemeka Victor Amachukwu, has been extradited from France to the US for spearphishing attacks on US tax preparers, resulting in the theft of $3.3 million from taxpayers.
Newly Discovered Vulnerabilities
- Trend Micro has confirmed active exploitation of critical security flaws (including zero-days) in on-premise Apex One Management Console, with mitigations released. The vulnerabilities have reportedly been exploited by Chinese threat actors.
- Researchers have uncovered multiple vulnerabilities in Dell’s ControlVault3 firmware (ReVault flaws), impacting over 100 laptop models. These flaws allow attackers to bypass Windows login and install persistent malware.
- Amazon ECS is affected by a newly discovered “ECScape” flaw, enabling cross-task credential theft and lateral movement within container environments.
- CyberArk Conjur contained multiple vulnerabilities that could be chained for unauthenticated remote code execution. Patches have been issued.
- CISA has issued an alert regarding a vulnerability affecting Microsoft Exchange.
- Security researchers have demonstrated that a single malicious document can exploit weaknesses in OpenAI’s Connectors to extract data from Google Drive without user interaction.
- Multiple reports from Black Hat USA and DEFCON 2025 highlight that HTTP request smuggling vulnerabilities (notably in HTTP/1.1) remain prevalent and are evolving, with many defences proving inadequate.
Notable Threat Actor Activity
- The ShinyHunters group is behind the recent wave of Salesforce data theft attacks, including the breach at Google.
- VexTrio, an ad fraud and subscription scam group, has been distributing fake VPN and spam blocker apps on Apple and Google app stores.

- Europol, led by French Police, has arrested a 38-year-old administrator of the Russian-language XSS cybercrime forum.
Trends, Tools, or Tactics of Interest
- Social engineering attacks have surged, with incidents nearly tripling in the first half of 2025 compared to late 2024 (from 6% to 17% of all incidents), per LevelBlue.
- Akira ransomware and other malware campaigns are abusing legitimate drivers (e.g., Intel CPU tuning/ThrottleStop) to disable antivirus and EDR processes, including Microsoft Defender.
- A new C2 evasion technique, “Ghost Calls,” uses TURN servers from conferencing apps (Zoom, Microsoft Teams) to tunnel traffic through trusted infrastructure.
- Security researchers have demonstrated that major enterprise AI assistants (ChatGPT, Copilot, Gemini, Salesforce Einstein) can be manipulated via crafted prompts to exfiltrate or manipulate data.
- Splunk researchers have developed PLoB, a behavioural fingerprinting system using AI to detect subtle post-login intrusion signals.
- AI tools are increasingly used to automate security operations: Microsoft launched Project Ire, an autonomous AI agent for malware classification, and Ox Security announced an AI agent that generates code to fix vulnerabilities.
- AI is significantly reducing workloads for vCISOs (by 68%), with SMBs increasingly relying on virtual CISO services.
- Sextortion scams remain persistent but are now considered background noise by security professionals.
- Perplexity AI is reportedly ignoring robots.txt directives and crawling websites regardless of opt-out signals.
Regulatory or Policy Developments Affecting the Security Industry
- Microsoft paid out a record $17 million in bug bounties over the past 12 months, rewarding 344 security researchers across 59 countries.
- WhatsApp has introduced a new security feature to help users identify potential scams when added to group chats by unknown contacts.
