BACKGROUND
BACKGROUND
Due to the challenging pandemic situation in Brunei Darussalam where the population is advised to stay at home, cybercriminals are taking the opportunity to phish sensitive and confidential information by creating a fake website for well-known fast-food chains.
Example:
https:// bn-mcdelivery .ru
This website appears to be hosted in Russia, and offers meals at a very low price, with many menu items that are not available in Brunei outlets.
Modus Operandi
BACKGROUND
Attackers are now actively exploiting Microsoft Exchange Servers using ‘ProxyShell’ vulnerability to install backdoors for later access, which uses three chained MS vulnerabilities to perform unauthenticated, remote code execution. These chained vulnerabilities are exploited remotely through Microsoft Exchange's Client Access Service (CAS) running on port 443 in IIS.
The three chained vulnerabilities used in ‘ProxyShell’ attacks are:
BACKGROUND
In view of the recent directive for organizations to activate their business continuity plan (BCP) protocols, most organizations are requiring employees to work from home (WFH). Remote working creates additional opportunities for cyber threat actors to perform malicious cyber activities by exploring open vulnerabilities in less secured networks, thus gaining access to users’ data or the organization's network.
RECOMMENDATIONS
Below are some security measures that can be applied:

Information-stealing malware was found on a device belonging to one of Microsoft's employees with access to account information for a small number of their customers, and the attacker has used the information in some cases to launch highly targeted attacks as part of a broader campaign.
BACKGROUND
BruCERT has recently received a number of reports on a scam called “MARISEWABANK”. The scammer contacts victims via SMS containing a WhatsApp link. Once the link is clicked, the victim would be lured into online gambling by promising a profit of 100% to 350% depending on the bank that the victim deposits their money into. The victim will then be asked for their personal and banking details, namely:
• Bank
• Name of account holder
• Account number
• Online banking username & password
BACKGROUND
BruCERT has received several complaints recently about a tele-survey phone scam allegedly from a company named Prolific, asking people for their personal email address purportedly to send a survey through email. However, the real purpose is to collect sensitive and personal information.
MODUS OPERANDI
BACKGROUND
According to a study, 91% of cyber-attacks start with an email. Scammers hack email accounts so that they can send messages from a trusted email address in hopes of getting the recipients to take action. Their main goal is to get these email contacts to send money, reveal personal information, or click on a link that installs malware, spyware, or a virus.
IMPACT
BACKGROUND
Trickbot is a malware-as-a-service botnet that is often described as one of the world's largest. It first appeared as banking malware in 2016, used to steal online banking credentials, and is designed to stealthily infiltrate a victim's computer and remain silent thus no particular symptoms are clearly visible on an infected machine.
BACKGROUND
Emotet started as a banking trojan in 2014 and has recently returned as a more dangerous malware targeting local government agencies. It acts as a downloader/dropper to deliver trojans and malicious code to infect devices. Emotet typically spreads through phishing emails or spam that contain Microsoft Word attachments or links along with zip files in order to bypass security filters (i.e. antivirus) to lure victims to click on the link or file.
IMPACT
BACKGROUND
The latest phishing attack has caused a wave of business email account takeovers.
Once an email account is compromised, the account credentials are sent to a remote bot which would then sign into the account and analyse recent emails. For each unique email thread, it would then reply to the most recent email, sending a link to a phishing page to capture credentials. Since the phishing emails are being sent as replies to genuine emails between suppliers, customers, and colleagues, this makes the emails appear trustworthy.
