Centralize logging or auditing using syslog. You can configure the BlackBerry 2FA. This task demonstrates one way to centralize logging. Back up the log4j. Open the log4j. To send log messages to a central syslog server, perform the following actions:. Change the value of log4j. To write log messages only to a syslog server, ALL, syslog.
To write log messages locally and to a syslog server, ALL, logfile, syslog. Phobos attacks have two main infection vectors: email phishing campaigns with malicious attachments, or gaining access to the system over Remote Desktop Protocol RDP. Attackers obtain RDP credentials by a variety of different methods.
They can conduct brute force attacks, leverage stolen credentials purchased from darknet marketplaces, or they can identify open, poorly configured, or vulnerable connections that can be exploited.
After gaining a foothold in the environment, the threat actor will attempt to move laterally via RDP. Phobos actors are known to prefer targeting servers rather than end user computers when deploying their ransomware attack.
The name Phobos is likely inspired by the Greek god who was believed to be the personification of fear and panic. CrySIS was first discovered in , but it gained a new level of popularity among threat actors when the original author released its source code that same year. After its decryption keys were leaked, the malware was rebranded as Dharma. Dharma operates under a Ransomware-as-a-Service RaaS model and is sold by multiple independent actors. Phobos appeared in the threat landscape late in as a successor to Dharma, after decryption tools and keys became available for the Dharma family.
Dharma and Phobos share code similarities and nearly identical ransom notes. The main difference between the two is how they encrypt files during an attack. Currently there is no decryption tool available for Phobos. Phobos is simplistic in design, which makes it popular with threat actors of varying technical abilities. It is also not packed or encrypted when compiled.
But this is not the case with Phobos, and statically analyzing the file gives some insight to its malicious intent. This threat is able to fingerprint a target system, list processes, manipulate files, interact with services, and modify registry keys.
These may include the following situations: The user account is removed from a BlackBerry Enterprise Server and the Desktop service books are manually removed from the BlackBerry smartphone.
An integrated email account is removed from a BlackBerry Internet Service account. Only the calendar database is restored from a backup file. Scenario 1 If there are two email account integration's with a BlackBerry Internet Service account, for example user gmail.
Open the Calendar application. Press the menu key. Choose Options. Type MOVE on the keypad. When prompted to move all appointments in the base system calendar, choose YES to accept the change. All entries in the Device Default calendar will move to the default active calendar. Perform a hard reset of the BlackBerry smartphone by removing and replacing the battery while the BlackBerry smartphone is powered on.
Select Show Keyboard. Scenario 2 If there are two email accounts integrated with the BlackBerry Internet Service account, for example user gmail. In the above scenario, it would be Desktop. Press the back arrow and save the changes if prompted. In the Advanced Options menu, choose Service Book. In the above scenario, it would appear as user gmail.
Press the menu key and choose Delete. Once all associated CICAL service books have been deleted, complete the following steps to merge all entries into the calendar listed in the default calendar as checked above: Open the Calendar application. This will move all entries in the Device Default calendar to the default active calendar. Once the BlackBerry smartphone has reset, resend the service books from the BlackBerry Internet Service to recover the service books that were deleted in the steps above.
