SMBleed: A New Critical Vulnerability Affects Windows SMB Protocol

SMBleed: A New Critical Vulnerability Affects Windows SMB Protocol

Jun 09, 2020
Cybersecurity researchers today uncovered a new critical vulnerability affecting the Server Message Block (SMB) protocol that could allow attackers to leak kernel memory remotely, and when combined with a previously disclosed "wormable" bug, the flaw can be exploited to achieve remote code execution attacks. Dubbed " SMBleed " ( CVE-2020-1206 ) by cybersecurity firm ZecOps, the flaw resides in SMB's decompression function — the same function as with SMBGhost or EternalDarkness bug ( CVE-2020-0796 ), which came to light three months ago, potentially opening vulnerable Windows systems to malware attacks that can propagate across networks. The newly discovered vulnerability impacts Windows 10 versions 1903 and 1909, for which Microsoft today released security patches as part of its monthly Patch Tuesday updates for June . The development comes as the US Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory last week warning Windows 10

Wanna Cry Again? NSA's Windows 'EsteemAudit' RDP Exploit Remains Unpatched

May 25, 2017
Brace yourselves for a possible 'second wave' of massive global cyber attack, as SMB ( Server Message Block) was not the only network protocol whose zero-day exploits created by NSA were exposed in the Shadow Brokers dump last month. Although Microsoft released patches for SMB flaws for supported versions in March and unsupported versions immediately after the outbreak of the WannaCry ransomware, the company ignored to patch other three NSA hacking tools, dubbed " EnglishmanDentist ," " EsteemAudit ," and " ExplodingCan ." It has been almost two weeks since WannaCry ransomware began to spread, which infected nearly 300,000 computers in more than 150 countries within just 72 hours, though now it has been slowed down. For those unaware, WannaCry exploited a Windows zero-day SMB bug that allowed remote hackers to hijack PCs running on unpatched Windows OS and then spread itself to other unpatched systems using its wormable capability.

How Nation-State Actors Target Your Business: New Research Exposes Major SaaS Vulnerabilities

Feb 15, 2024SaaS Security / Risk Management
With many of the highly publicized 2023 cyber attacks revolving around one or more SaaS applications, SaaS has become a cause for genuine concern in many boardroom discussions. More so than ever, considering that GenAI applications are, in fact, SaaS applications. Wing Security (Wing), a SaaS security company, conducted an analysis of 493 SaaS-using companies in Q4 of 2023.  Their study reveals  how companies use SaaS today, and the wide variety of threats that result from that usage. This unique analysis provides rare and important insights into the breadth and depth of SaaS-related risks, but also provides practical tips to mitigate them and ensure SaaS can be widely used without compromising security posture.  The TL;DR Version Of SaaS Security 2023 brought some now infamous examples of malicious players leveraging or directly targeting SaaS, including the North Korean group UNC4899, 0ktapus ransomware group, and Russian Midnight Blizzard APT, which targeted well-known organizat
