Security TangoWhat is the Security Tango The Security Tango is my name for the dance you have to do every time you want to assure yourself that your computer is free of viruses, spyware, keystroke loggers, backdoors, trojans, and other forms of malware click the Definitions button in the menu to see what all those things mean. Patch No Cd Rome Total War Barbarian Invasion Units. Its something you need to do regularly and often daily is not too often The simple act of getting on the Internet and downloading email or going to a Web page can expose your computer to malicious crackers who would love to take over your machine for their own use.

Im sure that those of you running Linux or a Macintosh used to laugh yourselves sick at all the machinations that your Windows using friends had to go through to keep themselves safe. But dont get too complacent your time is hereAs Linux and the Mac have become more popular, weve see more viruses for them. Yes, there are verified malware programs out there for both the Macintosh and for Linux. You need to protect yourself. Equally importantly, if you dont at least run an antivirus program, you run the risk of passing a virus on to your Windows friends assuming any of them actually talk to you. And thats just not being a good net citizen So Ive split the Tango into parts Windows, Linux, the Macintosh, etc. Ill add more as changes in technology warrant.

Email Servers. Overview. This joint Technical Alert TA is the result of analytic efforts between the Department of Homeland Security DHS and the Federal Bureau of Investigation FBI. This alert provides information on advanced persistent threat APT actions targeting government entities and organizations in the energy, nuclear, water, aviation, and critical manufacturing sectors. Working with U. S. DHS and FBI identified victims in these sectors. This report contains indicators of compromise IOCs and technical details on the tactics, techniques, and procedures TTPs used by APT actors on compromised victims networks. DHS assesses this activity as a multi stage intrusion campaign by threat actors targeting low security and small networks to gain access and move laterally to networks of major, high value asset owners within the energy sector. Based on malware analysis and observed IOCs, DHS has confidence that this campaign is still ongoing, and threat actors are actively pursuing their ultimate objectives over a long term campaign. The intent of this product is to educate network defenders and enable them to identify and reduce exposure to malicious activity. For a downloadable copy of IOC packages and associated files, see Contact DHS or law enforcement immediately to report an intrusion and to request incident response resources or technical assistance. Description. Since at least May 2. Historically, cyber threat actors have targeted the energy sector with various results, ranging from cyber espionage to the ability to disrupt energy systems in the event of a hostile conflict. Historically, threat actors have also targeted other critical infrastructure sectors with similar campaigns. Analysis by DHS, FBI, and trusted partners has identified distinct indicators and behaviors related to this activity. Of specific note, the report Dragonfly Western energy sector targeted by sophisticated attack group, released by Symantec on September 6, 2. This campaign comprises two distinct categories of victims staging and intended targets. The initial victims are peripheral organizations such as trusted third party suppliers with less secure networks. The initial victims are referred to as staging targets throughout this alert. The threat actor uses the staging targets networks as pivot points and malware repositories when targeting their final intended victims. The ultimate objective of the cyber threat actors is to compromise organizational networks, which are referred throughout this alert as intended target. Technical Details. The threat actors in this campaign employed a variety of TTPs, including open source reconnaissance,spear phishing emails from compromised legitimate accounts,watering hole domains,host based exploitation,industrial control system ICS infrastructure targeting, andongoing credential gathering. Using Cyber Kill Chain for Analysis. DHS leveraged the Cyber Kill Chain model to analyze, discuss, and dissect malicious cyber activity. Phases of the model include reconnaissance, weaponization, delivery, exploitation, installation, command and control, and actions on the objective. This section will provide a high level overview of activity within this framework. Stage 1 Reconnaissance. The threat actors appear to have deliberately chosen the organizations they targeted, rather than pursuing them as targets of opportunity. Staging targets held preexisting relationships with many of the intended targets. It is known that threat actors are actively accessing publicly available information hosted by organization monitored networks. DHS further assesses that threat actors are seeking to identify information pertaining to network and organizational design, as well as control system capabilities, within organizations. Forensic analysis identified that threat actors are conducting open source reconnaissance of their targets, gathering information posted on company controlled websites. This is a common tactic for collecting the information needed for targeted spear phishing attempts. In some cases, information posted to company websites, especially information that may appear to be innocuous, may contain operationally sensitive information. As an example, the threat actors downloaded a small photo from a publically accessible human resources page. The image, when expanded, was a high resolution photo that displayed control systems equipment models and status information in the background. Analysis also revealed that the threat actors used compromised staging target networks to conduct open source reconnaissance to identify potential targets of interest and intended targets. Targets of interest refers to organizations that DHS observed the threat actors showing an active interest in, but where no compromise was reported. Specifically, the threat actors accessed publically web based remote access infrastructure such as websites, remote email access portals, and virtual private network VPN connections. Stage 2 Weaponization. Spear Phishing Email TTPs. Throughout the spear phishing campaign, threat actors used email attachments to leverage legitimate Microsoft Office functions to retrieve a document from a remote server using the Server Message Block SMB protocol. An example of this request is file lt remote IP address Normal. As a part of the standard processes executed by Microsoft Word, this request authenticates the client with the server, sending the users credential hash to the remote server prior to retrieving the requested file. Note It is not necessary for the file to be retrieved for the transfer of credentials to occur. The threat actors then likely used password cracking techniques to obtain the plaintext password. Once actors obtain valid credentials, they are able to masquerade as authorized users. Stage 3 Delivery. When seeking to compromise the target network, threat actors used a spear phishing email campaign that differed from previously reported TTPs. The spear phishing email used a generic contract agreement theme, with the subject line AGREEMENT Confidential, and which contained a generic PDF document, titled document.
