Oval Tutu<p>📣 Just released Shöve v1.0.6!</p><p>Sometimes LESS is MORE - we saw up to 20% faster rendering on Steam Deck-like hardware by removing "clever" optimizations. Paradoxical?

🛡 H3lium@infosec.exchange/:~# :blinking_cursor:​<p>"🔍 Unveiling Sandman APT: The Silent Menace Targeting Global Telcos 🎯"</p><p>SentinelLabs has unearthed a new threat actor dubbed Sandman APT, primarily targeting telecommunication providers across the Middle East, Western Europe, and South Asia. This enigmatic group employs a novel modular backdoor named LuaDream, utilizing the LuaJIT platform, a rarity in the threat landscape. The meticulous movements and minimal engagements hint at a strategic approach to minimize detection risks. The LuaDream malware, a well-orchestrated and actively developed project, is designed for system and user info exfiltration, paving the way for precision attacks. The intriguing part? The attribution remains elusive, hinting at a private contractor or a mercenary group akin to Metador. The activities observed are espionage-driven, with a pronounced focus on telcos due to the sensitive data they harbor. The meticulous design of LuaDream showcases the continuous innovation in the cyber espionage realm, urging for a collaborative effort within the threat intelligence community to navigate the shadows of the threat landscape.</p><p>Source: <a href="https://www.sentinelone.com/labs/sandman-apt-a-mystery-group-targeting-telcos-with-a-luajit-toolkit/" rel="nofollow noopener" target="_blank">SentinelOne Labs</a></p><p>Tags: <a href="https://infosec.exchange/tags/SandmanAPT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SandmanAPT</span></a> <a href="https://infosec.exchange/tags/LuaDream" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LuaDream</span></a> <a href="https://infosec.exchange/tags/TelecomSecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>TelecomSecurity</span></a> <a href="https://infosec.exchange/tags/CyberEspionage" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CyberEspionage</span></a> <a href="https://infosec.exchange/tags/ThreatActor" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ThreatActor</span></a> <a href="https://infosec.exchange/tags/CyberSecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CyberSecurity</span></a> <a href="https://infosec.exchange/tags/LuaJIT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LuaJIT</span></a> <a href="https://infosec.exchange/tags/SentinelLabs" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SentinelLabs</span></a> <a href="https://infosec.exchange/tags/APT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>APT</span></a> 🌐🔐🎯</p> <p>Indicators of Compromise (IoCs):</p><ul><li>Domains: mode.encagil[.]com, ssl.explorecell[.]com</li><li>File Paths: %ProgramData%\FaxConfig, %ProgramData%\FaxLib</li><li>SHA1: <ul><li>fax.dat: 1cd0a3dd6354a3d4a29226f5580f8a51ec3837d4</li><li>fax.Application: 27894955aaf082a606337ebe29d263263be52154</li><li>ualapi.dll: 5302c39764922f17e4bc14f589fa45408f8a5089</li><li>fax.cache: 77e00e3067f23df10196412f231e80cec41c5253</li><li>UpdateCheck.dll: b9ea189e2420a29978e4dc73d8d2fd801f6a0db2</li><li>updater.ver: fb1c6a23e8e0693194a365619b388b09155c2183</li><li>fax.module: ff2802cdbc40d2ef3585357b7e6947d42b875884</li></ul></li></ul> <p>Author: Aleksandar Milenkoski, a seasoned threat researcher at SentinelLabs, has meticulously dissected the activities of Sandman APT, shedding light on the LuaDream backdoor.

clacke: exhausted pixie dream boy 🇸🇪🇭🇰💙💛Meanwhile back in 2010, Mike Pall of #<a href="https://libranet.de/search?tag=LuaJIT" class="" rel="nofollow noopener" target="_blank">LuaJIT</a> is doing some well-deserved gloating:<br><br><a href="http://lambda-the-ultimate.org/node/3851#comment-57760" rel="nofollow noopener" target="_blank">lambda-the-ultimate.org/node/3…</a><br><br>&gt; LuaJIT also does: constant folding, constant propagation, copy propagation, algebraic simplifications, reassociation, common-subexpression elimination, alias analysis, load-forwarding, store-forwarding, dead-store elimination, store sinking, scalar replacement of aggregates, scalar-evolution analysis, narrowing, specialization, loop inversion, dead-code elimination, reverse-linear-scan register allocation with a blended cost-model, register hinting, register renaming, memory operand fusion.<br><br>&gt; Due to the nature of a trace compiler, it implicitly performs partial and interprocedural variants of all of them. And many traditional optimizations, like straightening or unreachable code elimination are unnecessary.<br><br>&gt; All of that in 120KB for the VM and 80KB for the JIT compiler. And I didn't need 15 years and a billion dollar budget for that, either.
