Microsoft Exchange, Windows 11 hacked on second day of Pwn2Own
During the second day of Pwn2Own Berlin 2026, competitors collected $385,750 in cash awards after exploiting 15 unique zero-day vulnerabilities in multiple products, including Windows 11, Microsoft Exchange, and Red Hat Enterprise Linux for Workstations.
The Pwn2Own Berlin 2026 hacking competition takes place at the OffensiveCon conference from May 14 to May 16 and focuses on enterprise technologies and artificial intelligence.
Security researchers can earn over $1,000,000 in cash and prizes by hacking fully patched products in the web browser, enterprise applications, cloud-native/container environments, virtualization, local privilege escalation, servers, local inference, and LLM categories.
Popular node-ipc npm package compromised to steal credentials
Hackers have injected credential-stealing malware into newly published versions of node-ipc, a popular inter-process communication package, in a new supply chain attack targeting npm.
The node-ipc package is a Node.js module that enables various processes to communicate through all forms of sockets, including Unix, Windows, UDP, TLS, and TCP.
Despite the maintainer publishing in March 2022 weaponized versions that targeted Russia and Belarus-based systems with a data-overwriting module, in protest to the Russian invasion of Ukraine, the package still has more than 690,000 weekly downloads on npm.
Windows 11 and Microsoft Edge hacked at Pwn2Own Berlin 2026
On the first day of Pwn2Own Berlin 2026, security researchers collected $523,000 in cash awards after exploiting 24 unique zero-days.
Today’s highlight was Orange Tsai’s attempt, who was awarded $175,000 in rewards after chaining 4 logic bugs to achieve a sandbox escape on Microsoft Edge.
Windows 11 was also hacked three times by Angelboy and TwinkleStar03 (working with the DEVCORE Internship Program), Marcin Wiązowski, and Kentaro Kawane of GMO Cybersecurity, each earning $30,000 in cash rewards for demonstrating new privilege escalation zero-days.
Windows BitLocker zero-day gives access to protected drives, PoC released
A cybersecurity researcher has published proof-of-concept (PoC) exploits for two unpatched Microsoft Windows vulnerabilities named YellowKey and GreenPlasma, which are a BitLocker bypass and a privilege-escalation flaw.
Known as Chaotic Eclipse or Nightmare Eclipse, the researcher describes the BitLocker bypass issue as functioning like a backdoor because the vulnerable component is present only in the Windows Recovery Environment (WinRE), which is used to repair boot-related issues in Windows.
The latest exploits follow the researcher’s previous disclosure of the BlueHammer (CVE-2026–33825) and RedSun (no identifier) local privilege escalation (LPE) as zero-day flaws, both of which began to be exploited in the wild shortly after being publicly disclosed.
US govt seeks Instructure testimony on massive Canvas cyberattack
The U.S. House Committee on Homeland Security is calling on Instructure executives to testify about two cyberattacks by the ShinyHunters extortion group that targeted the company’s Canvas platform, allowing threat actors to steal student data and disrupt schools during final exams.
In a letter sent Monday afternoon to Instructure CEO Steve Daly, Homeland Security Committee Chairman Andrew R. Garbarino said the committee is investigating the massive breach at Instructure that impacts millions of students.
“The Committee on Homeland Security (Committee) is investigating the concerning reports related to recent cybersecurity incidents affecting Instructure Holdings, Inc. and the tens of millions of students, educators, and administrators who rely on its Canvas learning management platform,” reads the letter.
Signal adds security warnings for social engineering, phishing attacks
Signal has introduced new in-app confirmations and warning messages as additional safeguards against phishing and social engineering attempts that could lead to various forms of fraud.
The purpose is to introduce enough friction that users get the time to evaluate the safety of an external request.
Recently, there have been attacks targeting high-profile users with bogus ‘Signal Support’ alerts, as highlighted by the FBI, the Dutch government, and the German authorities.
JDownloader site hacked to replace installers with Python RAT malware
The website for the popular JDownloader download manager was compromised earlier this week to distribute malicious Windows and Linux installers, with the Windows payload found deploying a Python-based remote access trojan.
The supply chain attack affects those who downloaded installers from the official website between May 6 and May 7, 2026 via the Windows “Download Alternative Installer” links or the Linux shell installer.
According to the developers, the attackers modified the website’s download links to point to malicious third-party payloads rather than legitimate installers.
Instructure confirms hackers used Canvas flaw to deface portals
Education technology giant Instructure has confirmed that a security vulnerability allowed hackers to modify Canvas login portals and leave an extortion message.
BleepingComputer has learned that both the breach and defacements involved multiple cross-site scripting (XSS) vulnerabilities that enabled the attacker to obtain authenticated admin sessions.
The second hack was to draw attention and to pressure Instructure into entering negotiations to pay a ransom following an initial breach disclosed a week before.
