Ransomware
Sinclair Broadcast Group says a ransomware attack is still causing problems nearly three weeks after it happened. "Certain disruptions to...and the full extent of the impact on...business, operations and financial results is not known at the present time," the company said in a filing to the US Securities and Exchange Commission. Sinclair is the second-largest broadcast company in the US with 185 television stations that it owns or operates. A Russian cybercrime group known as Evil Corp is believed to be behind the attack. Malwarebytes has a case study that examines the impact of a ransomware attack and how best to respond to one.
The ransomware business model continues to evolve at pace, with the FBI warning that several gangs have been using financial information, including share valuations and mergers and acquisitions, to pressure victims into giving into their demands. “During the initial reconnaissance phase, cyber criminals identify non-publicly available information, which they threaten to release or use as leverage during the extortion to entice victims to comply with ransom demands,” the FBI said. It also warned that one ransomware gang had begun searching their victims’ networks for financial-related information they could use as leverage.
More positively, there has been some progress in law enforcement's efforts to combat ransomware. Europol said an international operation had targeted 12 people believed to be involved in more than 1,800 ransomware attacks on critical infrastructure and large organisations around the world. The suspects were detained in Ukraine and Switzerland and are described as "high-value targets" responsible for "wreaking havoc across the world." And the US government has offered a $10 million reward for information about the gang that disrupted much of the eastern US fuel supply network earlier this year.
