Dear ...
Reference: 48771955-A8
Court action will be the consequence of your ignoring this letter.
Despite our telephone calls on October 10 and our letters of September 25, 2014 and October 20, 2014, and your promise to pay, payment of your account has still not been received. If full payment is not received by October 22, 2014 court action will be taken against your company.
If you allow this to happen you will incur court costs and you may forfeit your company’s credit status because the name of your company will be recorded by the major credit reference agencies. This may deter others from supplying you.
You are also being charged debt recovery costs and statutory interest of 8% above the reference rate (fixed for the six month period within which date the invoices became overdue) pursuant to the late payment legislation.
To stop this from happening please pay in full now the overdue invoice which is also attached to this letter.
Yours truly,

Fake PDF invoice SPAM
- http://www.symantec.com/connect/blog...ore-you-expect
Oct 20, 2014 - "... Over the past week, Symantec has observed a spam campaign involving suspicious emails that masquerade as unpaid invoices. However, these suspicious emails come with a nasty surprise attached in the form of a malicious .pdf file.
Malicious .pdf file attached to suspicious email:
> http://www.symantec.com/connect/site...31/Fig1_19.png
While these invoices may appear to be legitimate because the sender’s email address may be associated with a major company, the emails contain spelling errors in the subject line and the body of the email contains just one line of text. Most business emails contain a personal greeting to the recipient and the sender’s signature, but these emails have neither. These signs should serve as warnings to users that the email is not what it claims to be. The attached .pdf file has malicious shellcode hidden inside of it that will be executed when opened with a vulnerable version of Adobe Reader... attackers are trying to exploit the Adobe Acrobat and Reader Unspecified Remote Integer Overflow Vulnerability (CVE-2013-2729) by triggering the vulnerability while parsing the crafted Bitmap encoded image... The embedded shellcode acts as a downloader which downloads a malicious executable file (Infostealer.Dyranges) from a remote location. The downloaded malware attempts to install itself as a service called “google update service”... If successful, the malware is then able to steal confidential information entered into Web browsers by the user. Symantec recommends that users exercise caution when opening emails and attachments from unexpected or unknown senders. We also advise that PDF viewers and security software be kept up-to-date. Symantec detects the malicious .pdf file used in this campaign as Trojan.Pidief*."

Dropbox phish - hosted on Dropbox
- http://www.symantec.com/connect/blog...hosted-dropbox
Updated: 18 Oct 2014 - "... In this scam, messages included links to a -fake- Google Docs login page hosted on Google itself. We continue to see millions of phishing messages every day, and recently we saw a similar scam targeting Dropbox users. The scam uses an email (with the subject "important") claiming that the recipient has been sent a document that is too big to be sent by email, or cannot be sent by email for security reasons. Instead, the email claims, the document can be viewed by clicking on the link included in the message. However, the link opens a -fake- Dropbox login page, hosted on Dropbox itself.
Fake Dropbox login page:
> http://www.symantec.com/connect/site...ropbox%201.png
The -fake- login page is hosted on Dropbox's user content domain (like shared photos and other files are) and is served over SSL, making the attack more dangerous and convincing. The page looks like the real Dropbox login page, but with one crucial difference. The scammers are interested in phishing for more than just Dropbox credentials; they have also included logos of popular Web-based email services, suggesting that users can log in using these credentials as well. After clicking "Sign in," the user’s credentials are sent to a PHP script on a compromised Web server. Credentials are also submitted over SSL, which is critical for the attack's effectiveness. Without this, victims would see an unnerving security warning.
Security warning:
> http://www.symantec.com/connect/site...ropbox%202.jpg
Upon saving or emailing the user's credentials to the scammer, the PHP script simply -redirects- the user to the real Dropbox login page. Although the page itself is served over SSL, and credentials are sent using the protocol, some resources on the page (such as images or style sheets) are not served over SSL. Using non-SSL resources on a page served over SSL shows warnings in recent versions of some browsers. The prominence of the warning varies from browser to browser; some browsers simply change the padlock symbol shown in the address bar, whereas others include a small banner at the top of the page. Users may not notice or understand these security warnings or the associated implications. Symantec reported this phishing page to Dropbox and they immediately took the page down..."

ThetaRay turns to maths to detect cyber threats
- http://www.reuters.com/article/2014/...0IA1JV20141021
Oct 21, 2014 - "As businesses face a growing threat of cyber attacks, Israeli start-up ThetaRay is betting on maths to provide early detection, enabling the shutdown of systems before damage can be done. The year-old company's first investor was venture capital firm Jerusalem Venture Partners. It is now also backed by heavyweights like General Electric, which uses ThetaRay to protect critical infrastructure such as power plants, and Israel's biggest bank, Hapoalim, which deployed the technology to detect bank account anomalies... Cyber security providers are moving away from protecting gateways with defenses such as firewalls to focus on detecting and preventing attacks before they penetrate organizations... Security experts estimate it can take more than -200- days to identify a cyber attack once it's been launched... Once a threat has been detected, ThetaRay leaves it up to humans to decide whether or not to shut down the system..."

Fake Malformed or infected word docs with embedded macro viruses

22 Oct 2014 - "We are seeing loads of emails with Malformed or infected word docs with embedded macro viruses they are what appears to be a genuine word doc attached which is malformed and contains a macro or vba script virus. Modern versions of Microsoft office, that is Office 2010 and 2013 and Office 365 have Macros disabled by default, UNLESS you or your company have enabled them. Opening this malicious word document will infect you if Macros are enabled and simply previewing it in windows explorer or your email client might well be enough to infect you... Do -not- open word docs received in an email without scanning them with your antivirus first and be aware that there are a lot of dodgy word docs spreading that WILL infect you with no action from you if you are still using an outdated or vulnerable version of word. This is a good reason to update your office programs to a recent version and stop using office 2003 and 2007. The risks in using older version are starting to outweigh the convenience, benefits and cost of keeping an old version going... All modern versions of word and other office programs, that is 2010, 2013 and 365, should open word docs, excel files and PowerPoint etc that are downloaded from the web or received in an email automatically in “protected view” that stops any embedded malware or macros from being displayed and running.

Flash Player exploit in-the-wild - CVE-2014-0569
- https://blog.malwarebytes.org/exploi...vulnerability/
Oct 22, 2014 - "... less than a week ago, a critical flaw in the Flash Player (CVE-2014-0569*) was patched and made public:
* https://helpx.adobe.com/security/pro...apsb14-22.html
The vulnerability had been privately reported to Adobe through the Zero Day Initiative group giving the firm the time to fix the issue before it became known to the world. Typically security researchers and criminals will be very attentive to such news and skilled reverse engineers will start looking at the patch to be able to reconstruct the exploit. All things considered, there is normally a certain amount of time before a proof of concept is released and then a little more time before that poc is weaponized by the bad guys... Kafeinee**... stumbled upon that same CVE in a real world exploit kit (Fiesta EK) only one -week- after the official security bulletin had been published... That means we have less and less time to deploy and test security patches. Perhaps this is not too much of a deal for individuals, but it can be more difficult for businesses which need to roll out patches on dozens of machines, hoping doing so will not cause malfunctions in existing applications. In any case, this was our first chance to test CVE-2014-0569 in the wild by triggering the Fiesta EK against Malwarebytes Anti-Exploit:
> https://blog.malwarebytes.org/wp-con...-2014-0569.png
It is crucial to patch any system running outdated Flash Player versions as soon as possible! You can check the version you are running (make sure to do this in all the browsers you use) by going here:
>> http://www.adobe.com/software/flash/about/
The bad guys are not going to run short of vulnerabilities they can weaponize at a quicker rate than ever before. This leaves end-users with very little room for mistakes such as failing to diligently apply security patches -sooner- rather than later..."

New banking details
Dear Bitstamp clients,
We would like to inform you that Bitstamp now has new bank details, please check attached file.
We would like to assure those of you who sent deposits to our old details that our old IBAN is still active and your transfers, if otherwise sent with correct information, should arrive without a problem.
Please note that SEPA transfers usually take 1 to 3 business days to arrive and would kindly ask those waiting for your SEPA transfers longer than usually to please send us a transfer confirmation so that we can examine our bank account log and locate your transfers.
Also for those waiting on deposits we ask for your patience; we have accumulated a long list of transfers which lack information or contain wrong information which means we need to manually go through all of them instead of our system sorting them automatically.
Best regards
CEO, Nejc Kodrič

Two exploit kits prey on Flash Player flaw patched only last week

23.10.2014 - "Two exploit kits prey on Flash Player flaw patched only last week... The integer overflow vulnerability in question (CVE-2014-0569*) can allow attackers to execute arbitrary code via unspecified vectors, and is deemed critical (high impact, easily exploitable)... the time period was very short, and technical information about the vulnerability and exploit code hasn't yet been shared online... The exploit kits are used to deliver the usual assortment of malware, and some of the variants have an extremely low detection rate... If you use Adobe Flash Player, and you haven't implemented the latest patches, now would be a good time to rectify that mistake."

FTC gets courts to shut down tech support scammers

This is a common scam, and the caller will often claim that the victim has a PC-based problem. In some cases people fall for this. It is estimated that PairSys made $2.5m from the scam and that it employed online adverts as well as phone calls as lures. "The defendants behind Pairsys targeted seniors and other vulnerable populations, preying on their lack of computer knowledge to sell ‘security' software and programs that had no value at all," said Jessica Rich, director of the FTC's Bureau of Consumer Protection... The defendants in the case, Pairsys, Uttam Saha and Tiya Bhattacharya, have agreed to the terms of a preliminary injunction, which includes an instruction to shut down their websites and telephone lines and not to sell on their customer data lists."

Oct 29, 2014 - "Cybercriminals and attackers are leveraging Google Drive site and brand to go under the radar and avoid detection. Just last week, a targeted attack* uses Google Drive as a means into getting information from its victims. This time, phishers are using a modified version of the legitimate Google Drive login page to steal email credentials. This attack can be considered an improved version of attacks seen earlier this year, which asked for multiple email addresses**.
Fake Google Drive Site: Users may receive an email that contains links that lead to the spoofed Google Drive site.
Spammed message containing links to fake site:

Fake Google Drive site:
> http://blog.trendmicro.com/trendlabs...akegdrive2.jpg
To trick the user into thinking nothing suspicious is afoot, the phishing site -redirects- the user to a .PDF file from a -legitimate- site about investments. However, this redirection to a site about investments may still raise suspicions as nothing in the email indicates the specific content of the “document” is related to finances.
After logging in, users are redirected to a legitimate site:
> http://blog.trendmicro.com/trendlabs...akegdrive3.jpg
... Mobile Users, Also Affected: Based on our investigation, this attack will also work on mobile devices. When users clicked the “Sign in” button, the PDF file download is prompted and the users’ credentials are sent out to the cybercriminals.
Screenshot of PDF prompt download in mobile devices:
> http://blog.trendmicro.com/trendlabs...drive_fig8.jpg
... Users should exercise caution when opening emails, even those from known contacts. Avoid clicking links that are embedded in emails. Users can also check first by hovering their mouse over the link; doing so can reveal the true URL of the link in the status bar. Users can also check the legitimacy of the site before sharing any personal data, be it login credentials or contact details. They can check if the site address has any discrepancy (misspellings, different domain names) from the original site (e.g., <sitename .com> versus <sitename .org>). They should also check the security of the site before sharing any information... We have notified Google about this phishing page."

Hacks use Gmail Drafts to update their Malware and Steal Data
- http://www.wired.com/2014/10/hackers...re-steal-data/
10.29.14 - "... Researchers at the security startup Shape Security say they’ve found a strain of malware on a client’s network that uses that new, furtive form of “command and control” — the communications channel that connects hackers to their malicious software — allowing them to send the programs updates and instructions and retrieve stolen data. Because the commands are hidden in unassuming Gmail drafts that are never even sent, the hidden communications channel is particularly difficult to detect. “What we’re seeing here is command and control that’s using a fully allowed service, and that makes it superstealthy and very hard to identify,” says Wade Williamson, a security researcher at Shape. “It’s stealthily passing messages back and forth without even having to press send. You never see the bullet fired.” Here’s how the attack worked in the case Shape observed: The hacker first set up an anonymous Gmail account, then infected a computer on the target’s network with malware. (Shape declined to name the victim of the attack.) After gaining control of the target machine, the hacker opened their anonymous Gmail account on the victim’s computer in an invisible instance of Internet Explorer — IE allows itself to be run by Windows programs so that they can seamlessly query web pages for information, so the user has no idea a web page is even open on the computer. 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. The malware responds with its own acknowledgments in Gmail draft form, along with the target data it’s programmed to exfiltrate from the victim’s network. All the communication is encoded to prevent it being spotted by intrusion detection or data-leak prevention. The use of a reputable web service instead of the usual IRC or HTTP protocols that hackers typically use to command their malware also helps keep the hack hidden. Williamson says the new infection is in fact a variant of a remote access trojan (RAT) called Icoscript first found by the German security firm G-Data* in August. At the time, G-Data said that Icoscript had been infecting machines since 2012, and that its use of Yahoo Mail emails to obscure its command and control had helped to keep it from being discovered. The switch to Gmail drafts, says Williamson, could make the malware stealthier still..."

Dangers of opening suspicious emails: Crowti ransomware
- http://blogs.technet.com/b/mmpc/arch...ansomware.aspx
28 Oct 2014 - "... MMPC has seen a spike in number of detections for threats in the Win32/Crowti ransomware this month as the result of new malware campaigns. Crowti is a family of ransomware that when encountered will attempt to encrypt the files on your PC, and then ask for payment to unlock them. These threats are being distributed through spam email campaigns and exploits. Crowti impacts -both- enterprise and home users, however, this type of threat can be particularly damaging in enterprise environments. In most cases, ransomware such as Crowti can encrypt files and leave them inaccessible. That’s why it’s important to back up files on a regular basis... We also recommend you increase awareness about the dangers of opening suspicious emails – this includes not opening email attachments or links from untrusted sources. Attackers will usually try to imitate regular business transaction emails such as fax, voice mails, or receipts. If you receive an email that you’re not expecting, it’s best to ignore it. Try to validate the source of the email first -before- clicking on a link or opening the attachment... The graph below shows how Crowti ransomware has impacted our customers during the past month.
Daily encounter data for Win32/Crowti ransomware:

Crowti is being distributed via spam campaigns with email attachments designed to entice the receiver to open them. We have seen the following attachment names:
VOICE<random numbers>.scr
IncomingFax<random numbers>.exe
fax<random numbers>.scr/exe
fax-id<random numbers>.exe/scr
info_<random numbers>.pdf.exe
document-<random numbers>.scr/exe

The attachment is usually contained within a zip archive. Opening and running this file will launch the malware... Our telemetry and research shows that Win32/Crowti is also distributed via exploits kits such as Nuclear, RIG, and RedKit V2. These kits can deliver different exploits, including those that exploit Java and Flash vulnerabilities... Crowti's primary payload is to encrypt the files on your PC. It usually brands itself with the name CryptoDefense or CryptoWall... we saw a Crowti sample distributed with a valid digital certificate which was issued to Trend... This is not associated with Trend Micro and the certificate has since been revoked. Crowti has used digital certificates to bypass detection systems before - we have previously seen it using a certificate issued to The Nielsen Company... There are a number of security precautions that can help prevent these attacks in both enterprise and consumer machines. As well as being aware of suspicious emails and backing up your files, you should also keep your security products and other applications up-to-date. Attackers are taking advantage of unpatched vulnerabilities in software to compromise your machine. Most of the exploits used by Crowti target vulnerabilities found in browser plugin applications such as Java and Flash. Making a -habit- of regularly updating your software can help reduce the risk of infection... we also recommend running a real-time security product..."
