COBALT MIRAGE Conducts Ransomware Operations in U.S.
(published: May 12, 2022)
Secureworks researchers describe campaigns by Iran-sponsored group Cobalt Mirage. These actors are likely part of a larger group, Charming Kitten (Phosphorus, APT35, Cobalt Illusion). In 2022, Cobalt Mirage deployed BitLocker ransomware on a US charity systems, and exfiltrated data from a US local government network. Their ransomware operations appear to be a low-scale, hands-on approach with rare tactics such as sending a ransom note to a local printer. The group utilized its own custom binaries including a Fast Reverse Proxy client (FRPC) written in Go. It also relied on mass scanning for known vulnerabilities (ProxyShell, Log4Shell) and using commodity tools for encryption, internal scanning, and lateral movement.
Analyst Comment: However small your government or NGO organization is, it still needs protection from advanced cyber actors. Keep your system updated, and employ mitigation strategies when updates for critical vulnerabilities are not available.

SYK Crypter Distributing Malware Families Via Discord
(published: May 12, 2022)
Morphisec researchers discovered a new campaign abusing popular messaging platform Discord content distribution network (CDN). If a targeted user activates the phishing attachment, it starts the DNetLoader malware that reaches out to the hardcoded Discord CDN link and downloads a next stage crypter such as newly-discovered SYK crypter. SYK crypter is being loaded into memory where it decrypts its configuration and the next stage payload using hardcoded keys and various encryption methods. It detects and impairs antivirus solutions and checks for d |

2021-01-08 20:19:37 | APT Horoscope (lien direct) | This delightful essay matches APT hacker groups up with astrological signs. This is me: Capricorn is renowned for its discipline, skilled navigation, and steadfastness. Just like Capricorn, Helix Kitten (also known as APT 35 or OilRig) is a skilled navigator of vast online networks, maneuvering deftly across an array of organizations, including those in aerospace, energy, finance, government, hospitality, and telecommunications. Steadfast in its work and objectives, Helix Kitten has a consistent track record of developing meticulous spear-phishing attacks... | Conference | APT 35 APT 35 APT 34 | |

2018-04-04 14:00:03 | Breaches Increasingly Discovered Internally: Mandiant (lien direct) | >Organizations are getting increasingly better at discovering data breaches on their own, with more than 60% of intrusions in 2017 detected internally, according to FireEye-owned Mandiant.
The company's M-Trends report for 2018 shows that the global median time for internal detection dropped to 57.5 days in 2017, compared to 80 days in the previous year. Of the total number of breaches investigated by Mandiant last year, 62% were discovered internally, up from 53% in 2016.
On the other hand, it still took roughly the same amount of time for organizations to learn that their systems had been compromised. The global median dwell time in 2017 – the median time from the first evidence of a hack to detection – was 101 days, compared to 99 days in 2016.
Companies in the Americas had the shortest median dwell time (75.5 days), while organizations in the APAC region had the longest dwell time (nearly 500 days).
Data collected by Mandiant in 2013 showed that more than one-third of organizations had been attacked again after the initial incident had been remediated. More recent data, specifically from the past 19 months, showed that 56% of Mandiant customers were targeted again by either the same group or one with similar motivation.
In cases where investigators discovered at least one type of significant activity (e.g. compromised accounts, data theft, lateral movement), the targeted organization was successfully attacked again within one year. Organizations that experienced more than one type of significant activity were attacked by more than one threat actor.
Again, the highest percentage of companies attacked multiple times and by multiple threat groups was in the APAC region – more than double compared to the Americas and the EMEA region.
When it comes to the most targeted industries, companies in the financial and high-tech sectors recorded the highest number of significant attacks, while the high-tech, telecommunications and education sectors were hit by the highest number of different hacker groups.
Last year, FireEye assigned names to four state-sponsored threat groups, including the Vietnam-linked APT32 (OceanLotus), and the Iran-linked APT33, APT34 (OilRig), and APT35 (NewsBeef, Newscaster and Charming Kitten).
