Siinqee Bank Ransomware Claim by LockBit5 (Sep 2026)

Claim Summary

On or around September 20, 2026, the ransomware group tracked as “lockbit5” allegedly posted Siinqee Bank to its dark web leak site. According to the threat actor, the Ethiopian financial institution was added as a victim on that date. The group claims to hold data belonging to the bank, though it has not disclosed a specific data volume. The listing describes Siinqee Bank as a licensed Ethiopian financial institution offering inclusive and innovative banking services.

This claim has NOT been independently verified. Yazoul Security has not confirmed that any data was exfiltrated, that systems were encrypted, or that the posting is authentic. Ransomware operators frequently post unverified or exaggerated claims to pressure victims into paying.

Threat Actor Profile

The claim is attributed to lockbit5, a name that appears to reference the broader LockBit ransomware lineage. The LockBit brand has historically been one of the most prolific ransomware operations, known for double extortion tactics, affiliate-driven attacks, and a leak site used to shame non-paying victims. However, the “lockbit5” label is not a well-documented, independently tracked variant in public research.

Notably, no public research references, known tooling, or confirmed victim counts are available for this specific actor. This absence of corroborating intelligence is a significant caveat. It is possible that “lockbit5” represents a rebrand, an opportunistic copycat, or an affiliate operating under a familiar name to borrow credibility. Without verified tooling or TTP data, defenders should treat the group’s identity and capabilities as unconfirmed.

Alleged Data Exposure

The leak site entry reportedly names Siinqee Bank and its domain, siinqeeebank.com, and lists Ethiopia (SO) as the country of operation. The group has not published a data volume, sample files, or proof-of-exfiltration beyond the listing itself. No download links, credentials, or data samples are referenced in this report, and none should be sought out.

Because the claimed data volume is “Undisclosed,” there is no reliable basis to assess the scale of any alleged exposure. Claims of this nature are sometimes accompanied by fabricated or recycled samples, so the absence of any proof further weakens the credibility of the posting at this time.

Potential Impact

If the claim were accurate, a breach at a licensed financial institution could expose customer records, internal communications, or operational data. For a bank serving retail and commercial customers, potential consequences include regulatory scrutiny, reputational harm, customer trust erosion, and possible fraud risk if personal or financial data were involved.

However, these are hypothetical outcomes based on an unverified claim. There is currently no confirmed evidence of data theft, encryption, or service disruption at Siinqee Bank. Financial sector organizations in the region should remain alert regardless, as the sector is a frequent target.

What to Watch For

• Any official statement from Siinqee Bank confirming or denying the incident.
• Publication of data samples or proof by the threat actor, which would raise credibility.
• Regulatory notifications from Ethiopian financial authorities.
• Reuse of known LockBit-associated tooling or infrastructure in future postings.
• Whether “lockbit5” accumulates additional victims, which may clarify its legitimacy.
