Bicom Listed by malas Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to pressure organisations by pairing intrusion with public leak-site listings, turning stolen internal material into leverage. In that landscape, a listing dated April 2023 tied the name Bicom to the group malas and to an intrusion path that exploited a Zimbra vulnerability—an attack surface that has repeatedly featured in real-world campaigns against mail and collaboration servers.

Public reporting on the incident is sparse. What is known is that Bicom appeared on a malas listing, that the group claimed internal files had been exfiltrated in a ransomware attack, and that the reported summary pointed to a Zimbra vulnerability. The number of people affected remains unknown, and fuller technical confirmation has not been laid out in the available record. Even with those limits, a claimed exfiltration of internal files matters because such material can contain operational, employee, or customer-related information that retains value long after the initial intrusion.

Inside the incident

According to the breach record, Bicom was listed by the malas ransomware group on April 09, 2023. The record describes internal files as having been exfiltrated in a ransomware attack and summarises the intrusion as using a Zimbra vulnerability. No confirmed figure for people affected is given; that count is unknown. Timing of the underlying intrusion beyond the listing date, the precise scale of data taken, ransom demands if any, and whether encryption was also deployed are not detailed in the available facts. The leak-site listing itself should be read as a claim by the group rather than as independently verified proof of every asserted detail.

Zimbra, as a collaboration and mail platform, has been a recurring target when unpatched or misconfigured instances are reachable. The record does not expand on which specific flaw was used, how initial access was obtained, or how long the actor may have remained inside the environment before any exfiltration. Those operational particulars are undisclosed.

Who is malas?

malas is known publicly as a ransomware actor that has used leak sites to name alleged victims and to threaten or stage the release of stolen data—a pattern consistent with double-extortion tactics seen across several ransomware brands. Such groups typically seek initial access through exposed services, stolen credentials, or known software weaknesses, then move to data theft and, in many cases, encryption. Public reporting on malas has associated the name with opportunistic targeting rather than a single narrow industry focus, though individual campaigns vary.

For this incident, the facts state only that Bicom was listed and that internal files were described as exfiltrated via a ransomware attack tied to a Zimbra vulnerability. No further victim-specific statements, file counts, or sample dumps are included in the record provided here. Claims that appear on a group’s leak site remain attributions by the actor until corroborated by the organisation or by independent investigation.

Bicom and its sector

Bicom is the organisation named in the listing. Public breach records of this type often supply little corporate background; the facts here do not describe Bicom’s legal structure, headcount, or full service catalogue. In general public knowledge, entities operating under the Bicom name have been associated with communications and collaboration technology—areas in which mail, voice, and related platforms are core products or internal tools. Organisations in that space commonly hold employee directories, configuration and support data, partner or customer contact records, and operational documentation.

A breach affecting such an organisation is consequential because internal files can intersect both the company’s own workforce and the external parties who rely on its systems or services. Even when customer databases are not explicitly named, internal repositories frequently contain enough identifying or contextual information to create follow-on risk. The absence of a published affected-person count does not remove that exposure pathway; it only leaves the scope unconfirmed.

What was likely exposed

The facts name the exposed material as internal files exfiltrated in a ransomware attack. They do not itemise folders, record types, or volume. Exact contents are therefore unconfirmed. Organisations that run mail and collaboration stacks such as Zimbra, and that maintain ordinary business operations, typically hold some mix of the following—though none of these can be asserted as proven contents of this incident:

• Internal email, calendars, and shared documents
• Employee directories, HR-related files, or access-related records
• Operational, support, or configuration material
• Partner, vendor, or customer contact and correspondence data

Without a detailed inventory from Bicom or from a verified dump analysis, any more specific claim would be speculation. Readers should treat “internal files” as a broad category whose sensitivity depends entirely on what those files actually contained.

What's at stake

For individuals whose information may have been present in internal files, the practical risks include targeted phishing that references real names, roles, or projects; credential-stuffing attempts if any passwords or reset material were stored insecurely; and social-engineering approaches that sound legitimate because they draw on genuine internal context. For the organisation, stakes include operational disruption, regulatory or contractual notification duties where personal data is involved, erosion of trust with staff and partners, and the longer tail of fraud attempts that can continue months after a listing appears.

Because the affected-person count is unknown and the file-level detail is undisclosed, it is not possible to state how widely those harms might land. The prudent posture is to assume that anyone who exchanged mail, contracts, or support traffic with Bicom around the relevant period could be in scope until clearer inventories are published.

If your data was in this claimed breach

If you believe you had a relationship with Bicom—as staff, partner, or customer—treat the listing as a prompt to tighten basic hygiene rather than as proof that your personal file was taken. Practical first steps include changing passwords on related accounts and enabling multi-factor authentication where available; watching for phishing that cites internal projects, invoices, or colleagues; and reviewing financial and email accounts for unexpected activity. If you were given temporary or shared credentials for any Bicom-related system, retire them and request fresh ones through official channels only.

You can also run a free exposure scan of your email address to check whether that address has already appeared in known breach datasets. That check will not confirm or deny presence in this specific incident, but it can surface other exposures that deserve the same care. Stay with official Bicom communications for any notification or support process; do not trust unsolicited messages that demand payment or urgent credential submission in connection with this event.
