Microsoft on Tuesday rolled out its first security update for 2026, addressing 114 security flaws, including one vulnerability that it said has been actively exploited in the wild. Of the 114 flaws, eight are rated Critical, and 106 are rated Important in severity. As many as 58 vulnerabilities have been classified as privilege escalation, followed by 22 information disclosure, 21 remote code

### Vulnerability https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L682-L684 https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L720-L722 `AES/CBC/PKCS5Padding` lacks authentication, making it vulnerable to padding oracle attacks and ciphertext manipulation. ### Impact Severity is considered low for internal uses of this library but if there's any consumer using these methods directly then this is considered critical. Unlikely to matter due to the design of how AES-256-CBC is used in conjunction with RSA and SHA-256 checksum within Jervis. Jervis uses RSA to encrypt AES keys and a SHA-256 checksum of the encrypted data in local-only storage inaccessible from the web. After asymmetric decryption and before symmetric decryption, a SHA-256 checksum is performed on the metadata and encrypted data. A...

### Vulnerability https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L463-L465 https://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L495-L497 Uses `PKCS1Encoding` which is vulnerable to Bleichenbacher padding oracle attacks. Modern systems should use OAEP (Optimal Asymmetric Encryption Padding). ### Impact Severity is considered low for internal uses of this library but if there's any consumer using these methods directly then this is considered critical. An attacker with access to a decryption oracle (e.g., timing differences or error messages) could potentially decrypt ciphertext without knowing the private key. Jervis uses RSA to encrypt AES keys in local-only storage inaccessible from the web. The data stored is GitHub App authentication tokens which will expire within one hour or less. ### Pat...

The internet never stays quiet. Every week, new hacks, scams, and security problems show up somewhere. This week’s stories show how fast attackers change their tricks, how small mistakes turn into big risks, and how the same old tools keep finding new ways to break in. Read on to catch up before the next wave hits. Honeypot Traps Hackers Hackers Fall for

Korean Air confirms a major data leak affecting 30,000 staff members after the Cl0p gang targeted a catering partner. Learn what data was stolen and the airline’s response to secure its data.

From university breaches to cyberattacks that shut down whole supply chains, these were the worst cybersecurity incidents of the year.

Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They’re going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn’t just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can

The pro-Russian hacktivist group known as CyberVolk (aka GLORIAMIST) has resurfaced with a new ransomware-as-a-service (RaaS) offering called VolkLocker that suffers from implementation lapses in test artifacts, allowing users to decrypt files without paying an extortion fee. According to SentinelOne, VolkLocker (aka CyberVolk 2.x) emerged in August 2025 and is capable of targeting both Windows
