    Din lipsa de timp, nu ma voi mai ocupa de aplicatiile desktop. Creez site-uri mici si mijlocii, scripturi, pagini, bug fixes, optimizari. Scriu cod curat si comentat. UPDATE: Dupa ce am vazut zeci de scripturi/pagini facute de unu si de altu', pot sa spun ca scriu caligrafic! Pentru site-uri complete ma pot ocupa si de gazduire si de configurarea serverului astfel incat site-ul sa fie predat "la cheie". Ofer si mentenanta unde este cazul. Backend: PHP + MySQL Frontend: HTML + CSS + jQuery / Bootstrap Metode de plata: Paypal sau Transfer bancar Plata: La finalizarea proiectului sau esalonat, de la caz la caz.

    OS X Auditor is a free Mac OS X computer forensics tool. OS X Auditor parses and hashes the following artifacts on the running system or a copy of a system you want to analyze: the kernel extensions the system agents and daemons the third party's agents and daemons the old and deprecated system and third party's startup items the users' agents the users' downloaded files the installed applications It extracts: the users' quarantined files the users' Safari history, downloads, topsites, LastSession, HTML5 databases and localstore the users' Firefox cookies, downloads, formhistory, permissions, places and signons the users' Chrome history and archives history, cookies, login data, top sites, web data, HTML5 databases and local storage the users' social and email accounts the WiFi access points the audited system has been connected to (and tries to geolocate them) It also looks for suspicious keywords in the .plist themselves. It can verify the reputation of each file on: Team Cymru's MHR VirusTotal your own local database It can aggregate all logs from the following directories into a zipball: /var/log (-> /private/var/log) /Library/logs the user's ~/Library/logs Finally, the results can be: rendered as a simple txt log file (so you can cat-pipe-grep in them… or just grep) rendered as a HTML log file sent to a Syslog server Author Jean-Philippe Teissier - @Jipe_ & al. Support OS X Auditor started as a week-end project and is now barely maintained. It has been forked by the great guys @ Yelp who created osxcollector. If you are looking for a production / corporate solution I do recommend you to move to osxcollector (https://github.com/Yelp/osxcollector) How to install Just copy all files from GitHub. Dependencies If you plan to run OS X Auditor on a Mac, you will get a full plist parsing support with the OS X Foundation through pyobjc: pip install pyobjc If you can't install pyobjc or if you plan to run OS X Auditor on another OS than Mac OS X, you may experience some troubles with the plist parsing: pip install biplist pip install plist These dependencies will be removed when a working native plist module will be available in python How to run OS X Auditor runs well with python >= 2.7.2 (2.7.9 is OK). It does not run with a different version of python yet (due to the plist nightmare) OS X Auditor is maintained to work on the lastest OS X version. It will do its best on older OS X versions. You must run it as root (or via sudo) if you want to use is on a running system, otherwise it won't be able to access some system and other users' files If you're using API keys from environment variables (see below), you need to use the sudo -E to use the users environment variables Type osxauditor.py -h to get all the available options, then run it with the selected options eg. [sudo -E] python osxauditor.py -a -m -l localhashes.db -H log.html Setting Environment Variables VirusTotal API: export VT_API_KEY=aaaabbbbccccddddeeee Changelog Download: OSXAuditor-master.zip or git clone https://github.com/jipegit/OSXAuditor.git Source: https://github.com/jipegit/OSXAuditor

    As part of its "October Patch Tuesday," Microsoft has today released a large batch of security updates to patch a total of 62 vulnerabilities in its products, including a severe MS office zero-day flaw that has been exploited in the wild. Security updates also include patches for Microsoft Windows operating systems, Internet Explorer, Microsoft Edge, Skype, Microsoft Lync and Microsoft SharePoint Server. Besides the MS Office vulnerability, the company has also addressed two other publicly disclosed (but not yet targeted in the wild) vulnerabilities that affect the SharePoint Server and the Windows Subsystem for Linux. October patch Tuesday also fixes a critical Windows DNS vulnerability that could be exploited by a malicious DNS server to execute arbitrary code on the targeted system. Below you can find a brief technical explanation of all above mentioned critical and important vulnerabilities. Microsoft Office Memory Corruption Vulnerability (CVE-2017-11826) This vulnerability, classified by Microsoft as "important," is caused by a memory corruption issue. It affects all supported versions of MS Office and has been actively exploited by the attackers in targeted attacks. An attacker could exploit this vulnerability either by sending a specially crafted Microsoft Office file to the victims and convincing them to open it, or hosting a site containing specially crafted files and tricking victims to visit it. Once opened, the malicious code within the booby-trapped Office file will execute with the same rights as the logged-in user. So, users with least privilege on their systems are less impacted than those having higher admin rights. The vulnerability was reported to Microsoft by security researchers at China-based security firm Qihoo 360 Core Security, who initially detected an in-the-wild cyber attack which involved malicious RTF files and leveraged this vulnerability on September 28. Microsoft Windows DNSAPI Remote Code Execution Vulnerability (CVE-2017-11779) Among other critical vulnerabilities patched by Microsoft include a critical remote code execution flaw in the Windows DNS client that affects computers running Windows 8.1 and Windows 10, and Windows Server 2012 through 2016. The vulnerability can be triggered by a malicious DNS response, allowing an attacker gain arbitrary code execution on Windows clients or Windows Server installations in the context of the software application that made the DNS request. Nick Freeman, a security researcher from security firm Bishop Fox, discovered the vulnerability and demonstrated how an attacker connected to a public Wi-Fi network could run malicious code on a victim's machine, escalate privileges and take full control over the target computer or server. Windows Subsystem for Linux Denial of Service Vulnerability (CVE-2017-8703) This denial of service (DoS) issue is yet another noteworthy vulnerability which resides in Windows Subsystem for Linux. The vulnerability, classified by Microsoft as "important," was previously publicly disclosed, but wasn't found actively exploited in the wild. The vulnerability could allow an attacker to execute a malicious application to affect an object in the memory, which eventually allows that the application to crash the target system and made it unresponsive. Microsoft Office SharePoint XSS Vulnerability (CVE-2017-11777) Another previously disclosed but not yet under attack vulnerability is a cross-site scripting (XSS) flaw in Microsoft SharePoint Server that affects SharePoint Enterprise Server 2013 Service Pack 1 and SharePoint Enterprise Server 2016. The vulnerability, also classified by Microsoft as "important," can be exploited by sending a maliciously crafted request to an affected SharePoint server. Successful exploitation of this vulnerability could allow an attacker to perform cross-site scripting attacks on affected systems and execute malicious script in the same security context of the current user. Besides these, the company has patched a total of 19 vulnerabilities in the scripting engine in Edge and Internet Explorer that could allow web pages to achieve remote-code execution, with the logged-in user's permissions, via memory corruption flaws. Just opening a web page could potentially land you in trouble by executing malware, spyware, ransomware, and other nasty software on the vulnerable computer. More RCE And Other Vulnerabilities Redmond also patched two vulnerabilities in the Windows font library that can allow a web page or document to execute malicious code on a vulnerable machine and hijack it on opening a file with a specially crafted embedded font or visiting a website hosting the malicious file. The update also includes fixes for a bug in Windows TRIE (CVE-2017-11769) that allows DLL files to achieve remote code execution, a programming error (CVE-2017-11776) in Outlook that leaves its emails open to snooping over supposedly secure connections. Other issues patched this month include two remote code execution flaws in the Windows Shell and a remote code execution bug in Windows Search. Microsoft also published an advisory warning user of a security feature bypass issue affecting the firmware of Infineon Trusted Platform Modules (TPMs). Surprisingly, Adobe Flash does not include any security patches. Meanwhile, Adobe has skipped October's Patch Tuesday altogether. Users are strongly advised to apply October security patches as soon as possible in order to keep hackers and cybercriminals away from taking control over their computers. For installing security updates, simply head on to Settings → Update & security → Windows Update → Check for updates, or you can install the updates manually. Via thehackernews.com
