A highly sophisticated PayPal email scam has been uncovered that is being used to deliver banking malware. Rather than promise the email recipient a sum of money or the opportunity to claim an inheritance from a long lost relative, this PayPal email scam claims a payment has been made to the victims account and that the money needs to be refunded.
The scam emails say that $100 has been fraudulently sent to the victims account and a refund is requested. The emails contain PayPal logos and appear to have been sent directly from PayPal. The emails appear to have been sent from the firstname.lastname@example.org email account. The message contains the subject line “You’ve got a money request”.
It is not clear how the attacker has managed to spoof the PayPal email account, or how the email manages to bypass the spam filter of Gmail.
If the victim responds to the email and makes the payment they will have lost $100; however, that is not all. The victim will also have malware loaded onto their computer. The malware will be loaded automatically regardless of whether the payment is made.
A link is contained in the email which the user must click to find out more about the transaction. The link contains a shortened URL and directs to a document detailing the transaction. The document has a goo.gl address and the link appears to be a jpeg image of the transaction details.
Chthonic Banking Malware Delivered via PayPal Email Scam
The malware that is installed is a variant of the infamous Zeus banking malware – Chthonic. This malware has been programmed to inject its own code and images into banking websites. When the victim visits their online banking website the malware captures login names, passwords, PIN numbers, and answers to security questions. Many banking malware variants target a small number of financial institutions; however, Chthonic is capable of recording information entered into more than 150 different banking websites. Victims are primarily in the UK, US, Russia, Japan, and Italy.
Chthonic isn’t the only malware delivered. Researchers at Proofpoint have determined that an additional previously unknown malware variant called AZORult is also installed onto victims’ computers. Little is known about this new malware variant.
As the sports spectacular fast approaches it is time to be on high alert for Rio Olympics email scams. The Olympics have not yet started, but the scammers have certainly been active. Many new Rio Olympics email scams have been spotted in recent weeks and the number will certainly increase as the opening ceremony draws closer.
Any large sporting event that attracts massive global media interest is a good opportunity for scammers. With sports fans hungry for news of the latest events, information about competitors, or the latest betting odds, it is all too easy for the guard to be let down. A scramble for last minute tickets sees scammers rake in hundreds of thousands of dollars.
Many scammers feel that the Olympics is shooting fish in a barrel season. Which sadly it is.
Kaspersky Lab has reported that the first Rio Olympics email scams were uncovered as early as 2015; however, as the opening ceremony draws closer activity has increased by several orders of magnitude. In the UK, Action Fraud – the National fraud reporting body – has already received reports of 47 cases of fraud relating to the Rio Olympics, which has resulted in attackers gaining more than £300,000 ($392,800) in funds.
Watch out for these Rio Olympics Email Scams
The Rio Olympics email scams are as diverse as the events being competed over the 17-day competition. It is therefore a time to be particularly cautious.
Criminals are after bank details for fraudulent transfers, credit card details to make purchases, personal data for identity theft, and login credentials for all manner of nefarious activities. It is a time for everyone to be on their guard. Be prepared for a barrage of Rio Olympics email scams over the next few weeks and keep your wits about you online.
Fake Tickets Scams
The price of a ticket to the opening ceremony will cost anywhere between $60 to $1,400, although touts are offering tickets at vastly inflated prices. Ticket prices to see the most popular events can cost several thousand dollars. If a scammer can get a victim to part with their hard earned cash it could potentially be a big payday. If you are still planning on attending and you haven’t yet purchased a ticket, only buy from official sellers.
Scammers have already registered a host of official-looking domain names to fool the unwary into purchasing tickets and parting with their credit card numbers. The websites use official logos that have been lifted from the Internet and appear genuine. Fake or cheap SSL certificates are also purchased making the connections appear secure, yet checks may not have been performed on the company. A SSL (website starting with https) does not guarantee it is genuine. Before parting with your money, at least perform a WHOIS search on the domain owner. Fake domains have usually been purchased in the past few weeks or months. Also perform some online checks to make sure the website is genuine.
Be aware that just because a website ranks highly in the search engines it doesn’t mean it is legitimate. Many scammers use search engine poisoning to increase the rank and position of their websites. They may even appear above those of official ticket vendors.
Many Rio Olympics email scams direct sports fans to unofficial ticket sellers and scam websites. You will at best pay over the odds for a ticket, but most likely you will just be giving your money to a scammer and no tickets will ever arrive in the post.
Congratulations! You Have Won!
If you receive an email informing you that you have won (insert amazing prize here), chances are it is a scam. If it sounds too good to be true, it most probably is. While many Rio Olympics email scams attempt to get individuals to disclose bank details and credit card information, a great deal attempt to obtain money by other means.
Many Rio Olympics email scams direct users to official looking scam websites. Be very careful about disclosing any information on any website during the Olympics.
Emails are sent with fake attachments which, if opened, will infect the email recipients’ computer with malware or ransomware. Malware can log keystrokes and obtain login credentials. Ransomware will encrypt files and a ransom must be paid in order to obtain decryption keys. Links contained in websites often direct users to malicious websites where drive-by malware downloads take place.
Olympics and Zika News
If you are a sports fan and you want to follow the latest news, search for sports sites online and bookmark the pages. Do not click links contained in emails that are delivered to your inbox or spam folder. Many people click on any links contained in emails that seem interesting. Doing so could prove very costly. Scammers are sending out fake news emails or links to legitimate stories. Those links do not direct the recipient to news websites, but to sites loaded with exploit kits which download malware and ransomware onto users’ computers.
Fake Prize Draws
Social media is awash with offers to enter prize draws to win tickets to the Olympics. Be exceptionally careful about disclosing any personal information on social media sites. Scammers often use fake prize draws to obtain sensitive personal data. Those data can be used for future email scams, or to gain access to online accounts. Phishing campaigns are rife during the Olympics.
Fake lottery scams are also commonplace. Emails are sent out in the millions telling recipients they have won a prize draw or lottery. To claim the winnings, it is necessary to pay an admin fee and disclose credit card details or provide bank details for the transfer along with other sensitive information. The golden rule is: If you have not entered the draw, you cannot have won it. If you are asked to make a payment in order to receive winnings it is likely a scam.
If in any doubt as to the legitimacy of an email, delete it. Chances are you have not won a competition you have not entered and you are not lucky enough to have won an all-expenses paid trip to Rio to see the Olympics. It is likely to be one of the many Rio Olympics email scams currently circulating cyberspace.

Locky Ransomware Replaces Dridex as the Top Email Security Threat
Locky was first identified in February 2016 and is believed to have been released by the criminal gang behind the Dridex banking malware. In fact, Locky is distributed using the infamous Necurs botnet, one of the largest botnets currently in operation. Necurs was also used to deliver Dridex malware, which was the top email security threat in Q1. Figures from Proofpoint suggest Locky has been used in 69% of email attacks involving malicious documents in Quarter 2, 2016.
Not only is Locky now the top email security threat, malicious message volume also increased significantly in quarter 2. Proofpoint charted the rise in malicious email volume and the Quarterly Threat Summary shows volume has increased by 230% since Q1, 2016.
Bear in mind that the huge rise in malicious emails occurred even though the Necurs botnet went silent in early June and Locky emails essentially stopped being delivered. However, the botnet did not remain inactive for long. By the end of June it was back with a vengeance, with huge volumes of Locky emails delivered as part of a massive new campaign.
Exploit Kits Are Mostly Delivering CryptXXX Crypto-Ransomware
While Locky may be the top email security threat, exploit kits still pose a major risk to businesses and personal computer users. The Angler exploit kit may have died a death in early June, but Neutrino has now taken over as the EK of choice. Neutrino is targeting numerous vulnerabilities and CryptXXX crypto-ransomware is the main threat. The ransomware variant only appeared in Q2, but it has fast become a major problem and the most common EK threat.
CryptXXX may now be the most prevalent EK ransomware variant in use; however, there has been an explosion in the number of ransomware variants in 2016. Since the final quarter of 2015, the number of ransomware variants has increased by a factor of between 5 and 6 according to Proofpoint. The majority of ransomware is delivered via exploit kits, although many users are directed to malicious websites via links delivered by spam email.
Fortunately, EK activity has fallen considerably since April. Angler EK activity started to decline in late April and by the start of June EK activity had dropped by around 96%. Since the end of June, EK activity has started to increase with Neutrino the main EK now in use. Fortunately, EK activity has not returned to pre April levels. So far at least.
CryptXXX has fast become one of the most prevalent strains of ransomware, although until recently infection was only possible via malicious websites. Now researchers at Proofpoint have spotted CryptXXX ransomware emails. The group behind the attacks have added a new attack vector. CryptXXX ransomware emails contain a Word document containing a malicious macro. If the macro is allowed to run it will load a VB script into the memory which will use Powershell to make contact with the attackers’ command and control server. Once a connection has been made, CryptXXX will be downloaded onto the victim’s computer. Authors have realized the benefits to be gained from adopting an affiliate model to help infect machines and now a number of new players have entered the ransomware market.
If a “ransomware kit” is provided, individuals with little hacking skill can conduct their own ransomware campaigns. The ransomware authors can charge a nominal fee for supplying the kit, and can also take a cut on the back end. When an affiliate infects a computer and a ransom is paid, the authors receive a cut of the payment. This model works well and there is no shortage of individuals willing to try their hand at running ransomware campaigns. The CryptXXX ransomware emails are being sent by an affiliate (ID U000022) according to Proofpoint.
Identifying CryptXXX Ransomware Emails
The CryptXXX ransomware emails are being sent with a subject line of “Security Breach – Security Report #Randomnumber.” The emails contain only basic information about a supposed security breach that has occurred. The security report is supplied as an attached Word document. The body of the email contains the date, time of the attack, the provider, location, IP address, and port. The email recipient is instructed to open the file attachment to view details of the attack and find out about the actions that should be taken.
The file attachment is given a name such as “info12.doc” according to Proofpoint. If the attached Word file is opened, a Microsoft Office logo is displayed. The user is informed that the document has been created in a newer version of Microsoft Office. The content of the document will only be displayed if macros are enabled. Enabling the macros will result in the VB script being loaded. Then ransomware will then be downloaded and users’ files encrypted.
There is no fix if files are encrypted. The victim must pay the ransom or lose their files. Once an infection has occurred, files can only be recovered from backups if the victim does not pay the ransom.
CryptXXX Ransomware Still Being Delivered by Neutrino
Since the demise of the Angler exploit kit, CryptXXX was moved over to Neutrino. There was a dramatic fall in infections as activity temporarily stopped; however, Invincea recently reported a surge in activity via compromised business websites. The SoakSoak botnet is being used to scan the Internet for vulnerable websites. The websites being targeted run the WordPress Revslider slideshow plugin. Scripts are appended to the slideshow that redirect visitors to a malicious site containing Neutrino.
CryptXXX will only be downloaded if the endpoint lacks certain security tools that would detect an installation. If Wireshark, ESET, VMware, Fiddler, or a Flash debugging utility is present, the ransomware will not be downloaded.
The Tennessee Board of Professional Responsibility has issued an alert warning of a new phishing scam after a number of attorneys received a fake notification of action phishing email.
The notification of action phishing email appears to have been sent from attorney regulatory agencies and requests the recipient clicks on a link or opens an infected email attachment to view the details of a new legal complaint. If the attachment is opened or the link is clicked, crypto-ransomware will be installed on the email recipient’s device. Files will be locked and a ransom demand will appear demanding payment in exchange for a decryption key.
Alerts Issued After Spate of Phishing Emails Received by U.S Attorneys
The Center for Internet Security also issued a cyber-alert recently after becoming aware of new email scams that were targeting U.S lawyers. Lawyers in Alabama, California, Florida, Georgia, Nevada, and Tennessee have all been targeted.
Last month, more than 50 lawyers reported receiving fake emails about new discipline investigations. The emails appeared to come from state disciplinary bodies and bar associations. The emails were designed to cause concern and prompt the recipient to click on links to find out more information.
In contrast to many phishing emails, this campaign appears to be targeted. The emails contain personal information about the recipient which may fool some attorneys into thinking the messages are authentic. The emails are particularly well written, which makes it harder to identify them as phishing scams.
While personal information is included, that information is likely to have been taken from attorneys’ websites or social media websites such as LinkedIn.
Some of the emails indicate a complaint has been filed against the recipient, some claim that the individual’s bar membership has lapsed. The links contained in the emails direct users to a spoofed website where a drive-by malware download occurs.
How to Identify a Notification of Action Phishing Email
Since the latest emails have been personalized and are well written, identifying them as fake is a little harder than with standard phishing emails.
To prevent a drive-by download of malware it is important to ensure that browsers and plugins are kept up to date. Email links from unknown recipients should not be clicked, and even if the email appears to be genuine care should be exercised.
If a notification of action phishing email appears to have come from a regulatory body, the recipient should visit the appropriate website by entering in the URL directly into their browser. Hovering the mouse arrow over the link will show the real address that that the recipient will be directed to if the link is clicked. Oftentimes this will display an alternate URL.
Anti-spam email solutions such as SpamTitan offer an additional level of protection. SpamTitan blocks 99.97% of spam emails from being delivered.
