Unpatched flaws turn Ollama’s auto-updater into a persistent RCE vector, researchers say

Researchers at Striga have identified two vulnerabilities (CVE-2026-42248 and CVE-2026-42249) in Ollama’s Windows auto-updater that could allow an attacker to install a persistent executable that runs at user login. CVE-2026-42248 fails to properly verify signatures of downloaded content, while CVE-2026-42249 is a path traversal flaw that allows an attacker to inject malicious code into the user's Startup folder. Exploitation requires control over the update response, with potential methods including compromising the update infrastructure or redirecting the client. The vulnerabilities affect Ollama versions 0.12.10 through 0.17.5, and users are advised to disable auto-updates and remove shortcuts from the Startup folder to mitigate risks.

CISA, Microsoft warn of active exploitation of Windows Shell vulnerability (CVE-2026-32202)

Attackers are exploiting CVE-2026-32202, a zero-click vulnerability in Windows Shell, allowing authentication of victims' systems without user interaction. This vulnerability stems from an incomplete patch for CVE-2026-21510 and has been used by the APT28 group with weaponized LNK files to bypass Windows security. Although Microsoft addressed these vulnerabilities in February 2026, the risk remains as opening a folder with a malicious LNK file can still connect victims' machines to the attacker's server, initiating an NTLM authentication handshake that exposes the victim’s Net-NTLMv2 hash. This affects various versions of Windows 10, 11, and Windows Server. Microsoft released a patch for CVE-2026-32202 on April 14, 2026, but did not label it as actively exploited until more than two weeks later, leaving security teams unaware of its urgency. Organizations are advised to apply the patch and consider blocking outbound SMB traffic to mitigate risks.

Even trusted apps can infect your PC with malware now

Recent supply-chain attacks are increasingly targeting well-known software such as CCleaner, Steam games, and Notepad++, allowing hackers to distribute malware through legitimate updates. The introduction of artificial intelligence has accelerated the frequency and sophistication of these attacks, with hackers compromising developers or exploiting third-party tools to inject malicious code. Notepad++ was specifically affected by a supply-chain attack where a compromised third-party tool led to the distribution of tainted software. Attackers use various strategies, including hacking developers' credentials, purchasing access, or compromising tools relied upon by developers. Antivirus software is crucial for protecting users from malware, even from trusted sources, as modern solutions have minimal impact on system performance.

Europe is abandoning WhatsApp and Signal: Why governments are introducing their own messaging apps

European officials are transitioning from messaging platforms like WhatsApp and Signal to state-controlled applications to reduce reliance on US technologies. Six nations—France, Germany, Poland, the Netherlands, Luxembourg, and Belgium—are implementing secure messaging systems for sensitive communications. NATO has its own solution, and the European Commission plans to finalize its transition by year-end. This shift is driven by cybersecurity threats, particularly targeting politicians through popular apps, prompting advice to deactivate Signal groups to prevent data leaks. Belgium has developed the BEAM app, controlled by the state, for official use, offering features like end-to-end encryption and participant management. The localization trend is influenced by geopolitical dynamics and past incidents highlighting Europe’s dependence on foreign technology. Additionally, transparency issues have emerged, as reliance on private messaging services has obscured communications related to significant contracts, such as vaccine agreements.

European civil servants are being forced off WhatsApp

Apps like Signal and WhatsApp are recognized for their end-to-end encryption but are increasingly seen as inadequate for organizational communication due to their consumer-grade design. Benjamin Schilz, CEO of Wire, points out the risks of using such apps for professional purposes. Recent cybersecurity threats, including a Russian espionage campaign targeting these applications, highlight the importance of advanced features like access controls and metadata management, especially for large organizations. Belgium's De Waele advocates for controlled communication environments that include only government employees to mitigate risks. Transparency advocates have raised concerns about the privacy features of consumer apps obscuring important decision-making processes, as exemplified by a situation involving Commission President Ursula von der Leyen and a vaccine deal. The re-election of former U.S. President Donald Trump has prompted a shift in priorities towards secure communication channels within European governments.

BlueHammer: Windows zero-day exploit leaked

A proof-of-concept (PoC) exploit called BlueHammer has been released on GitHub, targeting an unpatched local privilege escalation vulnerability in Windows. The exploit, attributed to users Chaotic Eclipse and Nightmare Eclipse, has been modified by security researchers to work on updated versions of Windows 10, 11, and Windows Server. The exploit manipulates Microsoft Defender to create a Volume Shadow Copy, allowing access to sensitive registry files and enabling the extraction of NTLM password hashes. This facilitates the alteration of a local Administrator's password and subsequent login. The exploit can duplicate the Administrator's security token and create a malicious Windows Service that runs with SYSTEM privileges. While there are no reports of BlueHammer being exploited by malicious actors, researchers warn that such PoC code can be weaponized quickly. Microsoft has committed to investigating reported security issues related to this vulnerability.

FBI, CISA issue PSA on Russian intelligence campaign to target messaging apps

The FBI and CISA issued a joint public service announcement about Russian hackers targeting commercial messaging applications like Signal and WhatsApp. The hackers use social engineering tactics to deceive users into giving up account access, including impersonating support personnel and prompting users to click on malicious links or provide sensitive information. Although the hackers have not yet bypassed the apps' end-to-end encryption, compromised accounts can lead to serious consequences, such as reading messages and launching further phishing attacks. The agencies recommend that users enhance their cybersecurity measures to protect against these threats. This campaign is part of a broader trend to undermine the security of messaging apps, with previous warnings about spyware and attempts to infiltrate Signal users, especially in conflict zones.
