North Korean Hidden Cobra APT targets Turkish financial industry with new Bankshot malware


North Korea-linked APT group Hidden Cobra (aka Lazarus Group) is targeting the Turkish financial system.

Experts from McAfee observed the hackers using the Bankshot implant in targeted attacks against the financial organizations in Turkey. The attack resembles previous attacks conducted by Hidden Cobra against the global payment network SWIFT.

Bankshot was first reported by the US DHS in December, now new variants of the malicious code were observed in the wild  The sample analyzed by McAfee is 99% similar to the variants detected in 2017.

The hackers used spear-phishing messages with a weaponized Word document containing an embedded Flash exploit that triggers the CVE-2018-4878, Flash vulnerability that was disclosed in late January.
Adobe promptly patched the vulnerability with an emergency patch, but many computers are still vulnerable because the owners did not apply the patch.

According to McAfee, the implant’s first target was a major government-controlled financial organization that was targeted on March 2 and 3.
Later, the same malware implant infected a Turkish government organization involved in finance and trade and a large financial institution.
The implant has so far not surfaced in any other sector or country. This campaign suggests the attackers may plan a future heist against these targets by using Bankshot to gather information.

McAfee’s report on the campaign says that one government-controlled financial organization, a government organization involved in finance and trade, and three large financial organizations.

The attackers leveraged the Flash exploit to deliver the Bankshot RAT.
“Bankshot implants are distributed from a domain with a name similar to that of the cryptocurrency-lending platform Falcon Coin, but the similarly named domain is not associated with the legitimate entity.” reads the analysis published by McAfee.

“The malicious domain falcancoin.io was created December 27, 2017, and was updated on February 19, only a few days before the implants began to appear. These implants are variations of earlier forms of Bankshot, a remote access tool that gives an attacker full capability on a victim’s system. “
Spear phishing messaged used a Word document with the filename Agreement.docx, that appears as a template for Bitcoin distribution.
Hidden Cobra bait document
When the open it, the code it contains download malicious DLLs from falcancoin.io domain.

Experts discovered that the DLLs communicate with three control servers whom URLs are hardcoded in the implants’ code.

“The implants (DLLs) are disguised as ZIP files and communicate with three control servers, two of them Chinese-language online gambling sites. These URLs can be found hardcoded in the implants’ code” continues McAfee.
The malicious code is able to perform several malicious operations, including file deletion, process injection, and exfiltration over command and control channel.
Further details, included the Indicators of Compromise (IoCs) are included in the analysis.

NiceHash: security breach leads to 60 million lost - Iceman is behind?

A dark day for crypto currency miners, NiceHash has been hacked. Closely to 60$ millions (4,736.42 BTC) have been stolen while the bitcoin is crossing the 14k$ mark for the first time.













The hacker's bitcoin address cleary shows the steal of  4,736.42 BTC in a window of 48 hours: https://bitinfocharts.com/bitcoin/address/1EnJHhq8Jq8vDuZA5ahVh6H4t6jh1mB4rq




NiceHash users are furious by the time of reaction of the team. It took about 24 hours to realise that big amounts have been stolen.

I've contacted a member of Iceman and knowing this security breach for some reason he explained that NiceHash actually owned their users bitcoin wallets in order to save transactions fees and collect unclaimed BTC. This issue leads to a massive security breach which allow access to all NiceHash wallets. He claimed that by reverse engineering of their miner client, Iceman group was able to access their API. Is Iceman really behind this attack?






NanoCore developper busted and senteced for 33 months

A hacker who was arrested and pleaded guilty last year—not because he hacked someone, but for creating and selling a remote access trojan that helped cyber criminals—has finally been sentenced to serve almost three years in prison.

Taylor Huddleston, 26, of Hot Springs, Arkansas, pleaded guilty in July 2017 to one charge of aiding and abetting computer intrusions by building and intentionally selling a remote access trojan (RAT), called NanoCore, to hackers for $25.

Huddleston was arrested in March, almost two months before the FBI raided his house in Hot Springs, Arkansas and left with his computers after 90 minutes, only to return eight weeks later with handcuffs.
This case is a rare example of the US Department of Justice (DOJ) charging someone not for actively using malware to hack victims' computers, but for developing and selling it to other cybercriminals.
Huddleston admitted to the court that he created his software knowing it would be used by other cybercrimina…

ICEMAN : Infecting Crystal Finance Millennium

Iceman gang member confirms that they are behind the introduction and spreading of malwares that have affected Crystal Finance Millennium, a Ukraine-based accounting software firm. Was this a political based attack? Read more to find out.
I’ve had a chance to speak to one of the gang member on XMMP and he confirmed that the Iceman group is behind this attack. They started by a simple web attack (SQLI which lead to web shell upload, no privilege escalation was needed) in order to gain access to the web servers of the company. He confirmed that the math was simple, the Ukrainian company had many clients in the financial and medical sector which facilitated the propagation of their malware. From the archived web page, it becomes apparent they provide accounting software, personalization of medical records, blood service and "full automation of the doctor's office" - contrary to what their company name suggests, it appears they are (mostly) focused on medical software.
