This is an epic month for Microsoft patches, though not a record-setting one. Redmond addressed 421 bugs in its own products this month - about 200 fewer CVEs than last month, but likely the new norm with AI-assisted vulnerability disclosures and fixes. The big news is that North Korea’s Lazarus Group (and possibly other miscreants) found and attacked one of these flaws as a zero-day in early June.The bug, tracked as CVE-2026-68820, is a use-after-free in the Windows Ancillary Function Driver for WinSock. “A locally authenticated attacker could run a specially crafted application on an affected system to trigger a race condition,” Redmond warned, adding that successful exploitation could allow an attacker to execute code with SYSTEM-level privileges, and with no user interaction required.
Microsoft credited Check Point researchers Moshe Marelus and David Driker with finding and reporting CVE-2026-68820, and the security shop’s threat intel lead told us that his analysts first observed attackers - namely North Korea’s Lazarus Group - battering this CVE at the beginning of June.“We are familiar with one successful implementation of the CVE - but we assume it was used widely in the campaign,” Sergey Shykevich, director of threat intelligence at Check Point, told The Register.He’s talking about Operation Dream Job, a long-running campaign targeting organizations worldwide, especially those in the defense sector, and attributed to Lazarus, an umbrella term for Pyongyang's government-sponsored goons who specialize in cryptocurrency theft, extortion attacks, and IT worker scams. It’s probably best known for the Sony Pictures Entertainment hack in late 2014 and the WannaCry ransomware outbreak in 2017, although the group has been active since at least 2009. Lazarus’ DreamJob campaigns have been around since 2020, and they use social engineering to lure job seekers with fake offers for high-profile positions, then trick the victims into clicking on malicious links or opening malware-laced documents. The goal in these attacks involves stealing IP and other sensitive data, conducting cyber spying missions, and collecting financial information.When Dream Job and Patch Tuesday collideThis new wave of attacks focuses on the defense sector in Europe and India with dream jobs impersonating Lockheed Martin and privacy-tech firm Enveil. Attackers created at least three fake Enveil sites, and some even ranked as the top search result, making them even more believable to job seekers - and harder to spot a phish. “In this campaign, the threat actor expanded its delivery method by leveraging impersonation websites and search engine optimization (SEO) techniques to distribute the trojanized applications, increasing its credibility and helping it evade some phishing-based detections,” Check Point researchers said in a Tuesday blog.
