Outlook PST file corruption can cause downtime and loss of productivity. Common reasons for corruption include large file size, system shutdowns, faulty hardware or software, and virus intrusion. Repair options include using the built-in Inbox Repair Tool (ScanPST.exe) or a third-party Outlook PST repair tool. It is recommended to regularly back up Outlook data and scan PST files for errors. If ScanPST fails, use the advanced tool Stellar Repair for Outlook. #Outlook #PSTrepair

Summary: ThreeAM ransomware has been actively attacking small and medium companies, encrypting their data and demanding ransom. The ransomware is linked to ex-Conti members' R&D and uses X/Twitter bots and Rust language for ransomware. It targets US businesses, especially small to medium enterprises, erases Volume Shadow copies, and appends '.ThreeAMtime' extension to encrypted files. The ransomware's infrastructure shows commonalities and links to other malware. The operators run a name-and-shame blog on TOR for double extortion. Proactive security measures are necessary to counter such threats.

Zloader, also known as Terdot, DELoader, or Silent Night, is a modular trojan with upgraded RSA encryption. It uses junk code, hashing API imports, and string encryption to prevent malware analysis. Zloader first emerged in 2015 and was publicly disclosed in 2016. It resurfaced in September 2023 with a new version. The loader module of Zloader has been significantly modified and now includes RSA encryption. There are fifteen distinct variants of Zloader, all using the same RSA public key. The latest version of Zloader is compiled for 64-bit Windows systems. Zloader employs obfuscation techniques to hinder malware investigation. hashtags: #Zloader #malware #RSAencryption
Summary:
- Commodity PCs' built-in sensors, such as microphones, unintentionally capture electromagnetic side-channel leakage from ongoing computation.
- This leakage can be conveyed through supposedly-benign channels like audio recordings and Voice-over-IP applications.
- Remote and passive analysis of these channels allows for physical side-channel attacks on computation without physical proximity or the ability to run code on the target.
- The captured computation-dependent leakage can be used to steal secret keys, detect web pages being loaded, and identify hidden opponents in online games.
