Cybercriminals in the APAC region and Australia are targeting enterprises by exploiting vulnerabilities in common platforms such as Atlassian, specifically launching sophisticated phishing attacks on regulatory bodies and companies. These attacks aim to pilfer employee credentials and compromise a company’s robust cybersecurity defenses.
According to Ryan Economos, Mimecast’s APAC discipline chief knowledge officer and expert in email safety, such sophisticated phishing attacks utilizing Atlassian as a cover are relatively rare. Despite the increasing sophistication of phishing attacks, fueled by phishing kits and AI-powered tools, cybercriminals can now carry out their malicious activities with greater ease.
As hackers set their sights on Atlassian workspaces, Japanese ISPs navigate a regulatory labyrinth, while a compliance cloak story unfolds.
According to Mimecast’s latest report, cybercriminals have devised a novel phishing scheme that leverages the threat of regulatory non-compliance as a hook to target employees at government agencies. The phishing assaults:
- Utilizing Atlassian’s standardized workspaces, as well as various unified platforms like Archbee and Nuclino, we successfully deployed a series of authentic-looking yet staff-sensitive email communications.
- To ensure regulatory alignment, the company issued an update to its device policy, prompting employees via email to upgrade their gadgets in order to maintain compliance with our organizational standards.
- Designed to deceive, this malicious link had been engineered to divert unsuspecting clicks to a fake portal, where cybercriminals could secretly gather sensitive information, including login credentials.
- Phishing emails containing malicious hyperlinks are often disguised as legitimate communications, frequently originating from seemingly authentic sources like Japanese Internet Service Providers (ISPs).
According to Mimecast’s report, the emails feature personalized elements that align with specific details about a “gadget” and contain numerous allusions to the respective corporate sphere being targeted, thereby enhancing campaign legitimacy.
“The sender ensures that the identifier remains consistent throughout, referencing the organization’s designated identifier with the intention of misleading customers into believing it is an internal communication.”
Sophisticated phishing attacks are increasingly deceiving victims with their realistic facades, making it crucial to stay vigilant.
While Economos initially targeted Australian regulatory bodies with its marketing campaign, it has since broadened its scope to encompass various industries, no longer limited to the legal sector. He underscored several key findings from the marketing campaign, underscoring the escalating complexity among malicious cyberactors.

What’s behind the curtain? Unpacking Atlassian’s role in fostering collaboration and innovation across diverse workspaces.
Economos highlighted the growing adoption of Atlassian workspaces as a significant innovation driving forward the market.
According to him, Mimecast observes malicious actors leveraging companies like OneDrive and Google Docs to host files or links for their campaigns; however, the abuse of workspaces such as Atlassian has historically been minimal.
A component of the marketing strategy consisted of an email masquerading as if it originated from Atlassian’s Confluence platform. Mimecast attributed a “noteworthy increase” in the use of Atlassian tools to evade detection in recent cyberattacks.
“Abuse of legitimate companies is a persistent and dynamic issue,” Economos noted. Attackers will exploit credible sources to host and disseminate their initiatives, seeking to avoid detection.
Harvesting of tracker information intelligence
The marketing campaign employed postmark URLs to reroute customers to a single workspace interface. Attackers exploiting postmark URLs can gather sensitive data, including geographical location, browser specifications, and click patterns within an email, allowing them to craft more persuasive phishing lures by leveraging this valuable intel.
Encoded URLs employ various techniques to obscure their true nature, rendering them unreadable.
A sophisticated phishing marketing campaign employed multiple techniques to obscure its true destination, according to cybersecurity firm Mimecast. The text rewrites as: This contains multiple redirect URLs, encoded characters, and the inclusion of monitoring parameters.
Enlisting unsuspecting Japanese ISPs
While the exploitation of Japanese ISPs is not unique to this phishing scam, Economos noted that they have fallen prey to such tactics on multiple occasions, mirroring earlier attacks.
“The extent to which malicious actors are willing to push the boundaries to orchestrate effective attacks on organizations is a concerning trend, according to expert analysis.”
Phishing attacks are expected to become even more straightforward to execute – and increasingly believable.
Phishing remains one of the most prevalent and pervasive cyber threats facing organisations, according to Economos.
As generative AI and machine learning advance, they are likely to amplify the complexity and precision of phishing attacks, enabling attackers to craft more convincing and targeted messages that evade even the most vigilant defenses. This requires defenders to stay vigilant in detecting and rapidly responding to emerging and innovative attack techniques.
As Economos noted, the most significant transformation has occurred in the speed and efficacy of phishing attacks, thanks to the proliferation of phishing kits, automation, and AI-driven technologies. “These platforms empower novice hackers to orchestrate massive attacks and enable them to rapidly create highly sophisticated phishing emails that can easily bypass traditional security measures.”
Economos highlighted the emergence of pretexting – a tactic where cybercriminals assume a persona to craft a convincing narrative or “pretext” that deceives phishers – alongside Business Email Compromise, as pivotal developments in the ever-evolving phishing threat landscape.
As our work environments continue to evolve, malicious actors are increasingly exploiting a range of vectors beyond email, targeting social media platforms, collaboration tools like Microsoft Teams, Slack, and OneDrive, as well as phishing attacks via phone calls or text messages designed to deceive unsuspecting victims.
