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.

Javascript Miner: Hacker's Wet Dream

Experiencing lags on your computer? You're probably running a miner that consumes 100% of your CPU. Coin Hive (a JavaScript based miner) is becoming rapidly popular among Malware developers.


Coinhive, as a tool, is a JavaScript library that website owners can load on their site. When users access the site, the Coinhive JavaScript code library executes and mines for Monero, but using the user's CPU resources.

Very smart idea as it was meat to be a replacer for publicities. Coinhive launched on September 14, and its authors advertise it as an alternative to classic advertising. Coinhive claims that webmasters can remove ads from their sites, and load the Coinhive library and mine for Monero using a small portion of the user's CPU while the user is navigating the site. Site owners can make money and support their business, but without peppering their visitors with annoying ads.

The idea got some traction, and two days after it launched The Pirate Bay ran it as a tes…

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?






ICEMAN: Banks holes like in Cheese

Operation "Emmenthal" is the nickname for a grand-scale phishing campaign targeting bank clients. The goal of the campaign is to receive fraudulent payments by taking actions (e.g. money transfers) on behalf of the legitimate end user.



By phishing the victims with a mobile application which mimics the bank’s genuine application, the hackers steals the two-factor-authentication tokens used during the login (both user/passwords and SMS verification code) and then issuing money transfers by SMS Services offered by the bank, together with sending these sensitive credentials to the hackers infrastructure.


The ICEMAN group, which first came to knowing after contacting me to claim responsibility for the Banrisul Bank attack in Brazil, now claim they have committed many of the reported "Emmental" attacks as well. The hacker’s intentions and motives are shown at first in this exclusive interview.


What was your goal of the attack?
