Microsoft Office 365 is being adopted by businesses at a staggering rate. Office 365 is now the most widely used cloud service in terms of number of users. One in 5 corporate employees use an Office 365 cloud service and, according to Gartner, 56% of businesses using cloud services use Office 365.
Any platform that attracts such high numbers of business users is a major target for cybercriminals. Hackers are developing innovative ways of attacking businesses and bypassing Office 365 protections to get their phishing emails delivered to inboxes.
Campaigns are tested on genuine Office 365 accounts to ensure Office 365 defenses are bypassed, before targeted campaigns are conducted on business users. Microsoft’s standard Exchange Online Protection (EOP) is not sufficient to block these threats. At a minimum, users need to pay for Advanced Threat Protection (APT) to provide the level of protection required to block the types of sophisticated phishing attacks that are fast becoming the norm.
Four campaigns that have recently been identified use novel tactics to evade detection and fool end users into disclosing their login credentials.
Custom 404 Error Pages Used to Host Office 365 Phishing Forms
Microsoft researchers identified a novel tactic being used in a phishing campaign targeting office 365 users – 404 error pages to host phishing forms. 404 error pages are displayed when a website visitor attempts to visit a page that does not exist. By customizing the 404 page and using it to host a phishing form, the attackers have a virtually unlimited supply of phishing URLs to use. Any random URL would bring up the 404 page and the phishing form. Many email security solutions would not detect the link as malicious.
Voicemail Notifications Used as Lure in Office 365 Phishing Campaign
Avanan researchers recently identified a phishing campaign that uses voicemail notifications as a lure to obtain Office 365 credentials. The emails include Microsoft Office 365 logos and notification of the time of a call, the caller number, and the length of the voicemail message.
The text and logos are combined into three images in the email and an HTML file is attached which the email claims is the voicemail message. If opened, the HTML attachment uses meta refresh to redirect a user from the locally stored HTML page to an Internet-hosted page where they are presented with an Office 365 login box. Credentials are required to listen to the message through the spoofed voicemail management system.
Office 365 Admin Credentials Targeted
Office 365 credentials are valuable, but none more so than administrator credentials. A typical employee may have an email account containing sensitive data and their credentials may allow a limited number of cloud resources to be accessed. A set of administrator credentials would give an attacker the ability to create new accounts, access other users’ accounts, send messages from their email accounts, and access a much greater range of resources.
Office 365 admins are being targeted in a campaign that uses Office admin alerts about time-sensitive issues to lure them into disclosing their credentials. Two common lures are a critical problem with the mail service and the discovery of an unauthorized access incident.
Attacks Use Credentials in Real Time
A phishing campaign has been detected in which the attackers use the data captured from fake Office 365 login forms to access the genuine Office 365 account in real-time. If the login fails, a warning is displayed requesting the user re-enter their credentials. When the correct credentials have been entered, the user is redirected to their real Office 365 inbox, most likely totally unaware that their credentials have been stolen.
These are just four new tactics being used by cybercriminals to gain access to the Office 365 credentials of business users. Without advanced anti-phishing defenses in place, many of these sophisticated phishing emails will be delivered to end users’ inboxes. Security awareness training for employees will go a long way toward strengthening your last line of defense, but unless the majority of email threats are blocked, data breaches will occur.
Businesses using Office 365 need to ensure their email security defenses are up to scratch and can detect and block advanced phishing threats. That means paying for Office 365 ATP or using a third-party anti-spam and anti-phishing solution.
With SpamTitan layered over Office 365, businesses will be protected from the full range of email-based threats. Advanced phishing techniques such as those detailed above are detected and neutralized by SpamTItan.
TitanHQ’s DNS filtering solution, WebTitan, adds another layer of security to protect against phishing attacks. WebTitan blocks all known malicious web pages and scans new websites for malicious content. Threats are detected and webpages are blocked before any content can be downloaded.

Hotels in America are being targeted by cybercriminals in a campaign spreading a remote access Trojan (RAT) called NetWiredRC. The RAT is delivered via malicious emails targeting financial staff in hotels in North America.
The campaign uses a typical lure to get recipients to open the attached file. The message claims there are invoices outstanding and the recipient is asked to validate payment. The invoices are included in a zip file attached to the email.
If the file is extracted and the executable is launched, the Trojan will be downloaded by a PowerShell script. The Trojan achieves persistence by loading itself into the startup folder and will run each time the computer boots. The malware gives the attacker full control over an infected computer. Files can be uploaded and downloaded, further malware variants can be installed, keystrokes can be logged, and credentials can be stolen.
The ultimate aim of the threat actors behind this campaign is not known, although most cyberattacks on hotels are conducted to gain access to guest databases and payment systems. If malware can be loaded onto POS systems, card details can be skimmed when guests pay for their rooms. It can be months before hotels discover their systems have been breached, by which time the card details of tens of thousands of guests may have been stolen. Hutton Hotel in Nashville, TN, discovered in 2016 that its POS system had been infected with malware for three years.
There have been several recent cases of cyberattacks on hotels resulting in guest databases being stolen and sold on darknet marketplaces. The data breach at Marriott resulted in the theft of 339 million records and Huazhu Hotels Group in China experienced a breach of 130 million records.
Data breaches can prove incredibly costly. The cost of the data breach at Marriott could well reach $200 million, but even smaller data breaches can prove costly to resolve and can cause serious damage to a hotel’s reputation.
The latest spam campaign shows just how easy it is to gain a foothold in a network that ultimately leads to a 3-year data breach or the theft of more than 300 records: The opening of an attachment by a busy employee.
Hotels can improve their defenses by implementing cybersecurity solutions that block the threats at source. SpamTitan protects businesses by securing the email system and preventing malicious messages from reaching end users’ inboxes. WebTitan is an advanced web filtering solution that allows hotels to block malware downloads and carefully control the websites that can be accessed by staff and guests.

TitanHQ has announced it has entered not a new partnership with one of the United Kingdom’s leading Managed Service Providers (MSPs), OneStopIT.
For more than 16 years, OneStopIT has been helping small to medium sized businesses (SMBs) implement enterprise-class technology solutions. The Edinburgh-based MSP is focused on providing process-driven IT solutions to growing organizations at an affordable price.
Through the company’s dealing with UK businesses it has become clear that one of the biggest problem areas is phishing. Phishing attacks on UK businesses are now occurring at record pace and those attacks are costing businesses dearly.
UK businesses need advanced, enterprise-level cybersecurity solutions, but at an affordable SMB-friendly price. To improve protection against phishing and malware attacks, OneStopIT turned to TitanHQ.
TitanHQ has developed powerful cloud-based solutions for the SMB marketplace that incorporate enterprise-grade security features, but at a price that is affordable for even the smallest business. These solutions have been developed to be delivered by MSPs and can be easily incorporated into MSP auto-provisioning, billing, and management systems.
Under the new partnership, OneStopIT will be offering its customers SpamTItan-powered advanced email security and anti-phishing protection, WebTitan-powered DNS-based web filtering, and an ArcTitan-powered email archiving service.

“ The proliferation of phishing threats across Office 365 is a real problem for SME’s in the UK and we’re partnering with a key vendor in this space to protect our customers and also give them the OneStopIT premium service they are used to,” said Ally Hollins-Kirk, CEO of OneStopIT.
Cabarrus County in North Carolina is the latest victim of a major Business Email Compromise attack. The scammers impersonated a building contractor that was constructing a new high school in the County and succeeded in redirecting a $2.5 million payment to their account.
One of the contractor’s email accounts was compromised and an email was sent to a contact at the County requesting a change to the usual bank account.
Any request for such a change naturally needed to pass checks, but since the scammers had sent through all the appropriate documentation, the banking information was changed. The scammers then waited until the next regular payment was made. That payment was for $2,504,601.
The missing payment was queried by the contractor, Branch and Associates, and an investigation uncovered the scam. The relevant banks were informed to freeze the accounts to prevent the money from being withdrawn, but despite the quick response, the banks were only able to recover $776,518.40. The scammers had managed to divert $1,728,082.60 to a variety of accounts and had pocketed the funds.
The County was protected by an insurance policy, but it only provided $75,000 of coverage. $1,653,082.60 of the funds had to be covered by the County, in addition to the costs of investigating the attack, implementing additional security measures, and the cost increase of its insurance premiums after making such a large claim.
In this case the transfer was substantially larger than the average fraudulent BEC wire transfer, but transfers of this magnitude are far from unusual. Figures released by the U.S. Financial Crimes Enforcement Network (FinCEN) show there has been a 172% increase in losses to BEC attacks since 2016. Attacks are also increasing in frequency. In 2018, 1,100 BEC attacks were reported by businesses and $310 million per month was lost to BEC attacks.
FinCEN’s report shows businesses in the manufacturing and construction industries are the most commonly targeted and face the greatest risk of attack, although all businesses need to be aware of the threat and should take steps to reduce risk.
Defending against BEC attacks requires a variety of technical and administrative safeguards. There is no single solution that can be implemented which will detect and block all BEC attacks.
BEC scams usually start with a phishing email, so steps should be taken to improve email security. Advanced email security solutions such as SpamTitan can identify and block these BEC threats. SpamTitan also provides protection against the second stage of the attack. In addition to scanning all incoming emails, SpamTitan also scans outbound email for potential threats coming from within the organization.
Not all threats can be blocked, even with highly advanced email security defenses, so it is essential for the workforce to be trained how to identify potential email threats. Policies and procedures should also be developed covering amendments to banking credentials and email requests for bank transfers over a certain size.
Companies that fail to take action to reduce risk could well find their losses included in next year’s FinCEN BEC financial losses report.
If you have not implemented an anti-spam solution, if you are unhappy with your current provider, or if you use Office 365 for email, contact the TitanHQ team today to find out more about improving your security posture and increasing your defenses against BEC attacks.
Email archiving solutions have been developed by many cloud service providers, but prices can vary considerably between products, even between products that include a virtually identical set of features. Finding the best value email archiving solution for your business can be a challenge.
While the difference in price may only be a dollar or two per user, when multiplied by the number of employees in the organization the cost difference can be of the order of several thousand dollars a year.
To help you get the best possible price on email archiving, we have created a 2019 email archiving price comparison grid. The grid includes some of the leading names in email archiving and gives a typical price per user per month and per year, along with the total annual cost for a business with 100 mailboxes. The prices were taken from price lists available on 04/05/2018.
As you can see from the grid, TitanHQ’s email archiving solution, ArcTitan, is very competitively priced and is an affordable solution for most businesses. Being cloud-based, an email archive is quick and easy to set up and no hardware or software is required.
