As you gear up to cheer your country in Olympics, cyber-criminals are leaving no stone unturned to trap sports fans by launching various kinds of tactics such as Ransomware, Trojan, Botnet, phishing and lottery scams.
Ransomware
Half of the year has passed by and we have witnessed various Ransomware such as Locky, Petya, Samas, Android.Trojan.SLocker.CV attacking individual computers, psonal mobile phones and business organizations. According to eScan research, cyber-crooks would be relying on social engineering techniques to lure Olympic lovers into clicking on links or giving their account credentials. The email recipients would presume the email to be genuine, unknowingly download the Ransomware by opening the file sent by the cyber crooks or malicious website. Ransomware may also delivered via drive-by download attacks on compromised websites. Drive-by-download are malicious pieces of a program that is downloaded to a computer without the users’ consent or knowledge. The malware delivered by drive-by download is usually classified as a Trojan horse, because it deceives the user about the nature of the website or email.
Botnet
eScan predicts that the wily culprits can also take the help of Botnets to deceive the users into falling prey. Botnet allows hackers to take control of many computers at the same time and turn them into zombies or bots. The word Botnet is coined from two words ‘robot’ and ‘network’. These are used to infect large number of PCs which are often controlled through a server. It acts as a communication resource for other devices. Therefore cyber-criminals can act as the master of a large ‘zombie network’ – or ‘bot-network’ – that is capable of delivering a Distributed Denial of Service (DDOS) attack or a huge spam campaign.
Recently we have come across various scams evolving Rio Olympic Games 2016. We would like to alert our users to restrain them from being victims.
Phishing
According to US-Cert, Phishing is an attempt by an individual or group to solicit personal information from unsuspecting users by employing social engineering techniques. Phishing emails are crafted to appear as if they have been sent from a legitimate organization or known individual. These e-mails often attempt to entice users to click on a link that will take them to a fraudulent website that appears legitimate. The user then may be asked to provide personal information, such as account usernames and passwords that can further expose them to future compromises. The cyber-criminals see opportunities in global events and 2016 Olympic Games are no exception. With the high demand for Olympic Games criminals have sensed this opportunity to create many fake websites by registering such domain names containing “rio” and “rio2016” to sell fake Olympic tickets for luring sports fans. According to the Wall Street Journal, there is an underground market for SSL certificates, which ensure a secure connection between a server and a web browser helps the sites look legitimate. The simple business model used here is where the recipients are asked to provide personal information including sensitive details like bank account details and card details to purchase the tickets.
Lottery Scams
Cyber-crooks are making use of e-mails written in English and Portuguese, to lure victims that they are the winners of ticket lottery organized by International Olympic Committee and the Brazilian Government. The spammers are attempting to convince e-mail recipients that their e-mail addresses have been chosen randomly from a large list. In order to claim their prize, the victims need to reply to the e-mail and furnish their personal information.

- Make sure you either implement MailScan at gateway level or enable Mail Anti-virus on endpoint in order to block extensions such as *.EXE, *.SCR, *.JS, *.VBE etc. These attachments would infect your system.
- Open e-mails only if you are positive about the source.
- Always check for “https” prefix before entering any financial information for electronic transmission over the internet.
