Phishing can take many forms and while email is the most common vector used in these scams, other types of phishing such as voice phishing (vishing), SMS phishing (Smishing), and social media phishing increasing. In particular, there has been a recent spike in social media phishing attempts.
The threat from email phishing can be greatly reduced with an email security solution; however, these solutions will do nothing to block vishing, smishing, and social media phishing attempts. Businesses can improve their defenses by also using a DNS filtering solution. DNS filters block attempts to visit malicious websites and work in tandem with email security solutions to block email phishing and can also block the web-based component of smishing attacks and social media phishing to a certain extent. Unfortunately, since the social media networks where phishing takes place are not malicious websites, it will not prevent people from encountering phishing attempts.
This is why security awareness training is so important. Security awareness training gives employees the skills they need to recognize and avoid phishing attempts, no matter where the phishing attack is conducted. By training the workforce on security threats, risky behaviors can be eradicated, and employees can be taught the signs of phishing to look out for. The SafeTitan Security Awareness Training platform also delivers training in real-time, in response to risky behaviors by employees. This ensures training is delivered instantly when risky behavior is detected and training is likely to have the greatest benefit.
Social Media Phishing
Two social media phishing campaigns have recently been identified by researchers at Malwarebytes, the goal of which is to obtain the credentials for social media accounts. If the credentials are disclosed, the attacker can access the victim’s account and use it to conduct further attacks on the victim’s followers. If the credentials for a corporate social media account are stolen, attacks could be conducted on all the company’s followers. These attacks abuse the trust customers have in the company. The two campaigns have been conducted on Twitter and Discord users. Both use social engineering to trick people into disclosing their account credentials.
Twitter Phishing Campaign
In the Twitter campaign, the scammer sends a direct message to the user informing them that their account has been flagged for hate speech and threatens an immediate suspension of the account unless action is taken. The user is told that they must authenticate the account via the Twitter Help Center, a link for which is provided in the message. The link directs the user to a phishing page that spoofs Twitter where they are asked to log in. If they do, their credentials will be captured.
Discord Phishing Campaign
The Discord campaign sees a message sent from either a contact of the victim using a compromised Discord account or from strangers. The account owner is accused of disseminating explicit photographs and the sender says they are going to block the account until an explanation is provided. A link is provided to a server where the recipient has allegedly been named and shamed. If the message recipient tries to respond to the message, their message will not be sent as they will have been blocked, increasing the likelihood of their clicking the link to the server.
Victims are required to log in via a QR code and once they have attempted that they are locked out of their accounts, which are then under the full control of the scammer. The scammer is then free to use the legitimate account to continue their scam on all the victims’ contacts. Social media scams such as these try to scare or shame users into responding. This tactic can be very effective, even if the user has never said a bad word on Twitter or sent an explicit photograph to anyone on Discord.
Other Social Media Phishing Campaigns
Phishing can – and does – occur on all social media platforms. One scam that has proven successful targets Instagram users and offers them the verified Instagram badge. In order to receive the badge, they are required to log in to verify their identity, naturally via a malicious link. Doing so will allow the scammer to take full control of the user’s Instagram account.
It is a similar story on LinkedIn. One of the most common scams involves impersonating a company and sending a message to an individual about a job offer, or a message suggesting they have been headhunted. Fake connection requests are also common. In this scam, the user is provided with a link to a scam site that spoofs LinkedIn and again is conducted to harvest credentials.
On Facebook, phishing scams are rife but often they seem innocuous. If you use Facebook, you will no doubt have seen countless posts asking site users to determine their band name, porn star name, pirate name, etc., by providing information such as the month and year of birth. Posts asking what was your first car? Where did you grow up? What was your favorite teacher’s name? and many more do not seek credentials, but the information disclosed can be used to answer security questions that are asked in order to recover accounts. These scams also make brute force attacks to guess passwords so much easier.
Dangers of Social Media Phishing
The loss of access to a social media account may not be the end of the world and is likely far better than having a bank account emptied, but the damage caused can be considerable. Many small businesses rely on social media for publicity and generating sales, and the loss of an account or scamming of customers can be devastating. The passwords used for social media accounts are often reused across multiple platforms. Scammers often conduct credential stuffing attacks on other platforms and accounts using the same password. Fall victim to a social media phishing scam and many other accounts could be compromised.
Blocking social media phishing attacks can be a challenge. You should also ensure that two-factor authentication is enabled on social media accounts, consider restricting who can send direct messages to your account, and who can view your profiles. If you encounter a scam, be sure to report it.
For businesses, employees with access to corporate social media accounts should be given specific training on social media phishing to ensure they can recognize and avoid phishing scams. The SafeTitan Security Awareness Training platform makes this simple and helps businesses instantly correct risky behaviors through the automated delivery of a relevant training course in real-time. The platform has a wealth of engaging, gamified training content and a phishing simulation platform for testing resilience to phishing attacks.
