Google wants to further improve email encryption, and the company partnered up with Comcast, Microsoft and Yahoo to submit a draft IETF specification for вЂњSMTP Strict Transport Security.вЂќ Essentially, Google and its partners want to make sure that encrypted email stays encrypted along its entire path fromВ sender to recipient. Google said that since introducing a visual element to mark unencrypted emails in Gmail 44 days ago, the amount of inbound mail sent over an encrypted connection increased by 25%. Use Microsoft Security Essentials, McAfeeвЂ™s Antivirus program or Norton Antivirus to scan your machine and eliminate malware. This is whatВ it looks like, so donвЂ™t be surprised if you see it in Gmail in the future: If youвЂ™re not sure how a hacker accessed your Gmail account, you should consider the very real possibility that malware was somehow installed on your computer. In its security update, Google also said that itвЂ™s improving its Safe Browsing warnings that appear in Gmail every time a user clicks on whatвЂ™s deemed to be aВ shady link that could lead toВ malware or phishing attacks. That means that вЂњfewer than 0.1% of usersвЂќ translates to as many as aboutВ 1 million users who may haveВ received warnings about their email being hacked by a government. ItвЂ™s a service that has more than 1 billion users as of February 2016. However, Gmail is not a nimble startup looking to take off.

Google did say that these warnings are rare, with вЂњfewer than 0.1% of users everвЂќ receiving one. With the Gmail drafts folder open and hidden, the malware is programmed to use a Python script to retrieve commands and code that the hacker enters into that draft field. This is what youвЂ™ll see if a government is trying to hack into your Gmail account:

Thus, it is able to bypass some security controls because it doesn't rely on any malicious domain.In addition to that bar, users will now get a full-page warning with instructions about how to stay safe, the company saidВ in an announcement on Thursday. 'Its most interesting features are the Virtual File System in FAT16 format and the ability to use the Gmail web UI to receive commands and exfiltrate data. 'Version four of ComRAT is a totally revamped malware family released in 2017,' ESET researcher Matthieu Faou said. The exfiltrated data comprises user details and security-related log files to check if their malware samples were detected during a scan of the infected systems.Д«ased on the Gmail email distribution patterns over a one-month period, ESET said the operators behind the campaign are working in the UTC+3 or UTC+4 time zones.

The 'legacy' mode, on the other hand, makes use of the already existing C2 infrastructure (ComRAT v3.x) to issue remote commands, the results of which are compressed and transmitted to a cloud service such as Microsoft OneDrive or 4Shared. In the final stage, the results of the command execution are encrypted and stored in an attachment (with the double extension '.jpg.bfe'), which is then sent as an email to a target address specified in the 'answer_addr.str' VFS file.

'document.docx,' 'documents.xlsx'), and deleting the emails to avoid processing them a second time.Дespite the '.docx' and '.xlsx' format in the filenames, the attachments are not documents themselves, but rather encrypted blobs of data that include a specific command to be executed: read/write files, execute additional processes, and gather logs. NET executable to interact with the victim's central MS SQL Server database containing the organization's documents.'ДЇor each email that meets the above criteria, the comRAT proceeds by downloading the attachments (e.g. 'In one case, its operators even deployed a. Cybersecurity researchers today uncovered a new advanced version of ComRAT backdoor, one of the earliest known backdoors used by the Turla APT group, that leverages Gmail's web interface to covertly receive commands and exfiltrate sensitive data. 'The main use of ComRAT is discovering, stealing, and exfiltrating confidential documents,' the researchers said. New ComRAT Malware Uses Gmail to Receive Commands and Exfiltrate Data. In addition, the PowerShell loader injects a module called ComRAT orchestrator into the web browser, which employs two different channels - a legacy and an email mode - to receive commands from a C2 server and exfiltrate information to the operators.

The firm said the first known sample of the malware was detected in April 2017.Д¬omRAT is typically installed via PowerStallion, a lightweight PowerShell backdoor used by Turla to install other backdoors. The ComRAT v4 (or 'Chinch' by the malware authors), as the new successor is called, uses an entirely new code base and is far more complex than its earlier variants, according to ESET.

BTZ's USB-stick infection mechanism in favor of injecting itself into every process of the infected machine and executing its primary payload in 'explorer.exe.' Newer versions of ComRAT backdoor have since ditched Agent.
