The Maze ransomware gang has threatened to publish information stolen from an American firm that overhauls airliners and installs flight control software upgrades – because its victim refused to pay a demanded ransom.

In a “press release” published on its leaks website, Maze raged against victims who refused to play its game and cough up vast sums of money to decrypt their illicitly encrypted data.

Among those recent targets was VT San Antonio Aerospace, a maintenance, repair and overhaul (MRO) company in Texas. A subsidiary of ST Engineering, VT San Antonio was said to have lost 1.5TB of data to the Maze criminals. Its MRO customers include Air Canada, Fedex and UPS Airlines.

Earlier this week the Maze gang highlighted ST Engineering for not paying the ransom, a sensible action that busts the gang’s business model.

In its post the gang complained that ST Engineering’s ransom negotiator “lied” before declining to take part in “further negotiation” with them, promising: “Soon it will be the time for weapon contacts, contracts for alteration of airplanes for first persons, contracts with dictatorship countries, contacts for cybersecurity systems for government structures. We just can’t understand what cybersecurity they are talking about as they have an Australia size security hole in their security perimeter.”

Ed Onwe, veep and general manager of VT San Antonio Aerospace, told The Register that local authorities had been informed of the ransomware attack as the firm figured out how to respond to the initial infection, adding: “As part of this process, we are conducting a rigorous review of the incident and our systems to ensure that the data we are entrusted with remains safe and secure. This includes deploying advanced tools to remediate the intrusion and to restore systems.

“We are committed to responding to this incident transparently and proactively, and already have begun notifying potentially affected customers. We will be working with our customers and industry peers to share insights and any lessons learned so that they can learn from our experience.”

The Maze gang has stepped up its public-facing activities in recent weeks, not without cost to itself. Last week it sent a ransom demand to the wrong company, having mixed up two firms’ names. It has also targeted Posh Spice’s perfumers and other celebrity lawyers, about whom El Reg will be writing more soon. Its tactics include leaking selected files publicly to apply further pressure to victims, in the hope they pay the demanded ransom, as well as – it now seems – ranting away when they refuse to play the game.

Current British government advice is never to pay a ransomware demand: it not only encourages and enriches the crooks but there’s no guarantee that they’ll delete your data as they promise. ®
