Cron - The Banking Trojan


Couple of days ago, the world's cyber crime media has announced the arrest of Cron. This "little" gang -

Every day Cron malware attempted to steal money from 50-60 clients of different banks. The gang's infection vector included spam SMS messages and fake applications.







In April 2016, an announcement about the lease of a mobile Trojan called cronbot appeared on a famous hacker forum (http://exploit.in). According to its description, the Trojan had the functionality to intercept SMS messages and calls, send USSD requests, and perform web injections. Group-IB assumed that the criminal group decided to recruit a new member to the team, because according to the author of the announcement, they were ready to provide the Trojan to one person only. At the time, the group consisted of the organizers, operators, "cryptors", "traffickers" and money mules.



Cron planned to start their "international activity" with attacks targeting banks of France. They developed special web injections for the following French financial institutions: Credit Agricole, Assurance Banque, Banque Populaire, BNP Paribas, Boursorama, Caisse d'Epargne, Societe Generale and LCL.

However, by November 2016, Russian legal enforcement with support from Group-IB had managed to identify all members of the group and collect digital evidence of the crimes committed. On November 22, 2016, a large-scale operation was carried out in 6 Russian regions: 16 Cron members were detained. The last active member of the group was detained in early April in St. Petersburg.

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.
