New Clues In Sony Hack Point To Insiders, Away from DPRK

A strong counter-narrative to the official account of the hacking of Sony Pictures Entertainment has emerged in recent days, with the visage of the petulant North Korean dictator, Kim Jong Un, replaced by another, more familiar face: former Sony Pictures employees angry over their firing during a recent reorganization at the company. Researchers from the security firm Norse allege that their investigation of the hack of Sony has uncovered evidence that leads, decisively, away from North Korea as the source of the attack. Instead, the company alleges that a group of six individuals is behind the hack, at least one a former Sony Pictures Entertainment employee who worked in a technical role and had extensive knowledge of the company’s network and operations. [Read Security Ledger coverage of the hack of Sony Pictures Entertainment.] If true, the allegations by Norse deal a serious blow to the government’s account of the incident, which placed the blame squarely on […]

Clues Point to Long-Duration Hack at Sony

With each passing day, evidence mounts that the attack on Sony Pictures Entertainment was a long-duration hacking event that gave malicious actors extensive access to the company’s network and data. The hack started out looking like a particularly nasty example of hacktivism – with thousands of SPE systems wiped of all data. Going on two weeks after revelations of the hack, however, the incident appears to be something much more dire: a massive breach of corporate security that gave malicious attackers access to gigabytes – and possibly terabytes- of sensitive data. With only a fraction of the allegedly stolen data trove released, the ripple effects of the incident are already washing up against other Sony divisions and firms with direct or indirect ties to the company. The latest developments in the saga include publication of some 40 gigabytes of internal files. As described by buzzfeed.com, the files include: “email exchanges with employees regarding specific […]

Report: Sony Fits Pattern of other Destructive Hacks

At a time when companies are warned to be on the lookout for “low and slow” attackers who studiously avoid notice, the Sony breach will be remembered for its unusual ferocity. On Nov. 24, the assailants declared their presence by decorating employee desktops with a belligerent message before erasing the hard drives of computers and servers they compromised as a parting shot. Destructive hacks such as the one on Sony are atypical. But they are not unknown. In fact, the attack on Sony shares many similarities with at least two other recent, destructive cyberattacks: from the methods used to carry out the strike to the software used to compromise Sony’s computer systems. Those earlier hacks also suggest that attackers had access to Sony’s network long before they played their hand. Read more over at The Christian Science Monitor.

DPRK Mum as Hackers Dump Sony Pictures Data Online

The hack of Sony Pictures Entertainment has taken a turn for the worse, as evidence has turned up that suggests hackers have ransacked the networks of the high-profile studio, dumping everything from unreleased films to detailed business and employee records online. A spokesman for the Democratic People’s Republic of Korea (DPRK) did not explicitly deny or take responsibility for the attack when contacted by the BBC, telling the British news agency that “the hostile forces are relating everything to [North Korea]. I kindly advise you to just wait and see.” Sony Pictures’ network was attacked using destructive “wiper” malware last week that stole and exfiltrated data from the company, then erased data on infected PCs and servers. An FBI FLASH alert sent to U.S. firms provided details on the malware, including its use of a hard-coded list of IP addresses and hostnames, and the inclusion of configuration files created on computers […]

FBI: Destructive Malware Used Korean Language Packs

In a first, the F.B.I has issued a warning to U.S. businesses to be on the lookout for destructive malware that was used in an attack last week on Sony Pictures Entertainment. The FBI issued a five-page “FLASH” warning to security professionals at U.S. companies to warn them of the new malware. A copy of the warning viewed by The Security Ledger revealed that the malware deployed a number of malicious modules, including a version of a commercial disk wiping tool on target systems. Samples of the malware obtained by the FBI contained configuration files created on systems using Korean language packs. The use of Korean could suggest a link to North Korea, though it is hardly conclusive. It does appear that the attack was targeted at a specific organization. The malware analyzed by the FBI contained a hard coded list of IP addresses and computer host names. Media reports have linked the malware to the […]
