Signal Plans New Security Measures After Russian Hackers Hijack Hundreds of Accounts

 

Following revelations that hackers tied to the Russian government breached numerous German users' accounts via focused phishing schemes, Signal, a secure messaging service, moves to strengthen its defenses. Though the core encryption stays intact, manipulation tactics targeting people - not systems - spark renewed alarm among experts. Some reports suggest around 300 people in 

Germany faced incidents, such as prominent politicians. 
The head of the German parliament ranked among them, showing a shift toward targeting authorities, campaigners, and well-known personalities. Though less common before, such actions now point to more deliberate choices by offenders. What happened did not involve any break-in at Signal’s core security setup. Their encryption methods stayed intact throughout the incidents. Hackers found another path - using deceptive messages aimed directly at people. 

These tricks led some users to hand over private login details without realizing it. The app itself remained untouched, including its built-in privacy safeguards. Reportedly, fake messages came from someone pretending to be "Signal Support," arriving straight in user inboxes. Instead of ignoring them, some people gave up their single-use login codes, personal Signal PINs, along with backup account information. 

With that data in hand, intruders then activated the targeted accounts on separate devices. Private conversations became reachable - all because stolen details allowed full transfer control. Earlier warnings came from security experts across Europe, along with U.S. agencies like the FBI, flagging such tactics recently. Phishing efforts resembling these have drawn attention due to their repeated appearance. 

Targets included individuals speaking out against China’s policies, according to reports. These patterns hint at coordinated monitoring backed by governmental support. Observers note the consistency in techniques points beyond random attacks. Human behavior plays a central role in these breaches, differing from conventional hacks targeting code flaws. 

Instead of cracking software defenses, intruders gain access by persuading individuals to disclose credentials. Once granted entry through trust rather than force, encrypted environments offer little resistance. Security analysts observe a shift: tricking people now works better than overcoming digital barriers. What used to require complex tools now succeeds with conversation. Now working on new protections, Signal aims to make scam detection easier for its users. 

Without revealing exact details, the team mentioned updates targeting phishing-driven breaches. These adjustments will start appearing within weeks. Changes are expected to limit how often accounts get compromised through deceptive messages. Although the group operating Signal emphasizes strong privacy safeguards, these very protections reduce how much information they can gather. 

Because messages are secured with end-to-end coding, personal chats remain hidden even from the service itself. Limited access to usage details means deeper inspection of scam attempts becomes difficult. Only minimal traces of activity stay visible, due to built-in system constraints. Later updates show Signal warning people: real support teams won’t message inside the app, on social platforms, by text, or call asking for logins, access codes, or personal IDs. 

Messages from the team arrive strictly via confirmed accounts ending in @signal.org, according to their statement. Communication like this stays limited - no exceptions appear. Despite strong encryption, hacking through stolen credentials shows weaknesses still exist at the human level. With scams now harder to spot, specialists stress vigilance alongside tools like two-step checks - protection depends on behavior, not code alone.

Phishing Cases Drop in Hong Kong, But Losses Surge as Scammers Turn to Account Takeovers

 

Phishing incidents in Hong Kong declined sharply last year, yet the financial damage caused by such scams rose significantly, according to police. While fewer cases were reported, the total amount lost by victims climbed to HK$110 million (US$14 million), highlighting a shift in cybercrime tactics.

Authorities recorded 1,093 phishing cases in 2025, a 60 per cent drop from 2,731 incidents the previous year. Despite this decline, overall losses jumped by 112.9 per cent, with the average loss per case increasing more than four times to around HK$100,000. Police attributed this rise to increasingly sophisticated methods used by scammers, who are now focusing on gaining control of victims’ accounts instead of merely collecting credit card details.

“Previously, phishing links were sent aiming to obtain credit card information,” said acting senior superintendent Rachel Hui Yee-wai of the cyber security and technology crime bureau, adding that scammers would then simply use the information to make unauthorised purchases
“But in recent years, these links aim to take over accounts – they could be people’s securities accounts, online banking accounts or even WhatsApp accounts to go on and scam friends and family.”

In one example shared by authorities, a fraudster impersonated a WhatsApp administrator and asked a victim to provide a login verification code. The victim complied, unknowingly giving the scammer full access to the account.

“This effectively allowed scammers to take control … the victim basically handed the account over and let others view all the activity and content,” she said.

The attacker then leveraged the compromised account to conduct further scams, ultimately causing the victim to lose HK$19 million. Police noted that such incidents demonstrate how phishing schemes have evolved into more complex operations involving identity theft and social engineering.

Separately, a large-scale phishing simulation conducted by police revealed that employees across Hong Kong remain vulnerable to these attacks, especially when messages appear to originate internally. The exercise, carried out between October and January, involved 301 organisations and more than 53,000 participants who were unknowingly sent simulated phishing emails and SMS messages.

Results showed that 13.4 per cent of participants clicked on malicious email links, up from 11.5 per cent a year earlier. Among those who clicked, nearly half submitted personal information, while 6.4 per cent uploaded data or downloaded files. At least one employee in 89 per cent of participating organisations fell for a phishing email.

Senior staff were found to be more susceptible, with a click rate of 15.5 per cent compared with 13 per cent among general employees. Messages disguised as internal communications proved particularly effective. Emails posing as IT department notifications offering gifts had the highest click rate at 6.7 per cent, followed by file download alerts.

A separate SMS phishing test involving 3,620 participants showed a lower click rate of 5.9 per cent, though 70 per cent of organisations still had at least one employee engage with a malicious link. In real-world scenarios, SMS remains a dominant channel for scammers, accounting for over 90 per cent of phishing attempts, often masquerading as government agencies, banks, or courier services.

Police also highlighted the increasing use of artificial intelligence in crafting phishing attacks, enabling criminals to produce highly realistic messages and fake websites.

“They can use AI or other tools to make the website almost identical to the genuine one … even the logo is the same,” Hui said.

Officials warned that such advancements make it harder for individuals to identify fraudulent communications, particularly when combined with psychological tactics like urgent security alerts designed to lower suspicion.

Authorities said they will continue enhancing prevention and enforcement measures, including using AI to detect suspicious websites and collaborating with telecom providers to block scam messages. The public is advised to stay cautious, avoid clicking on unknown links, and verify requests for sensitive information through official sources.
